Diverticular Disease

Diverticular disease is the general name for a common condition that involves small bulges or sacs called diverticula that form from the wall of the large intestine (colon). Although these sacs can form throughout the colon, they are most commonly found in the sigmoid colon, the portion of the large intestine closest to the rectum. Diverticulosis refers to the presence of diverticula without associated complications or problems. The condition can lead to more serious issues including diverticulitis, perforation (the formation of holes), stricture (a narrowing of the colon that does not easily let stool pass), fistulas (abnormal connection or tunneling between body parts), and bleeding. Diverticulitis refers to an inflammatory condition of the colon thought to be caused by perforation of one of the sacs. Several secondary complications can result from a diverticulitis attack, and when this occurs, it is called complicated diverticulitis.

Analysis of the Epidemiological Trends on Inpatient Diverticulosis Admissions in the US: A Longitudinal Analysis From 1997-2018.

Cureus, 15(2):e34493.

Background Diverticulosis of the colon is characterized by outpouchings of mucosa and serosa through the muscular layer of the large intestinal wall. It is classically associated with increasing age with older individuals having a higher prevalence and greater density of diverticula secondary to its progressive disease nature. Also, diverticular disease is associated with dietary habits, low fiber intake in western society as well as obesity. The aim of this study was to investigate the epidemiological trends associated with diverticular disease in the United States in a 21-year interval from 1997 to 2018. Methods Using the Nationwide Inpatient Sample, all hospitalizations between 1997 and 2018 were analyzed. We examined annual data for hospitalization rate, the average length of stay (LOS), mean age and interval age groups, and hospital charges for inpatient admissions for diverticular disease (diverticulitis and diverticulosis). Results Between 1997 and 2018, the number of hospitalizations for patients with a primary discharge diagnosis of diverticular disease (diverticulosis and diverticulitis) increased 32% from 220,896 to 293,530 with 89.7 discharges per 100,000 persons in 2018 versus 81.0 discharges per 100,000 persons in 1997. Overall, the average age of patients decreased from 67.55 ± 0.15 years in 1997 to 64.59 ±0.08 in 2018, [t-value (t) 12.56, degrees of freedom (df) 514424, 95% confidence interval (CI) 2.497-3.423, P<0.0001]. On further evaluation, the mean average age in males decreased from 63.16±0.21 years in 1997 to 61.31±0.12 years in 2018, (t 8.16, df 217981, 95% CI 1.404-2.295 P<0.0001), while in females it decreased from 70.53±0.14 years to 67.15±0.10 years, (t 20.13, df 296422, 95% CI 3.050-3.709 P<0.0001), in the same interval time. While evaluating different subgroups of age in this time interval, the prevalence rate of diverticular disease diagnosis per 100,000 persons increased in the interval age between 18-44 years from 20.1 to 29.8, [relative risk (RR) 0.848, CI 95% 0.834-0.863, P< 0.0001) and 45-64 years from 107.1 to 125.3, (RR 0.761, CI 95% 0.754-0.769 P<0.0001) while it decreased in the interval age between 65-84 years from 357.6 to 259.7, (RR 1.211, CI 95% 1.206-1.226, P<0.0001) as well as > 85 years from 746.2 to 523.6, (RR 1.130, CI 95% 1.112-1.147, P<0.0001) The length of stay (LOS) mean average in days decreased from 5.8 ± 0.04 days in 1997 to 4.4±0.021 days in 2018, (t 33.08 df 514424, 95%CI 1.316-1.483, P< 0.0001). Hospital Inpatient National Statistics data over hospital mean charges, available from the period between 1997 to 2015, shows that the mean hospital charges in US dollars increased over 100%, from $19,735.17 in 1997 to $39,575 in 2015 (P<0.001) even after adjusting values to 2015 inflation. Conclusion There is an overall trend of decreased mean age of patients admitted with diverticular disease in the US over the past 21 years with a respective significant increased rate of disease in younger age groups. We postulate that these changes may be associated with poor dietary habits and obesity epidemics worsened in the last two decades in the US. In addition, despite the decreased length of stay over the same time period, the mean hospital charges more than double likely reflecting the increased access to expensive diagnostic methods such as computed tomography and colonoscopies.

Smoking, Alcohol consumption, and 24 Gastrointestinal Diseases: Mendelian Randomization Analysis.

eLife, 12: pii:84051 [Epub ahead of print].

Background: Whether the positive associations of smoking and alcohol consumption with gastrointestinal diseases are causal is uncertain. We conducted this Mendelian randomization (MR) to comprehensively examine associations of smoking and alcohol consumption with common gastrointestinal diseases. Methods: Genetic variants associated with smoking initiation and alcohol consumption at the genome-wide significance level were selected as instrumental variables. Genetic associations with 24 gastrointestinal diseases were obtained from the UK Biobank, FinnGen study, and other large consortia. Univariable and multivariable MR analyses were conducted to estimate the overall and independent MR associations after mutual adjustment for genetic liability to smoking and alcohol consumption. Results: Genetic predisposition to smoking initiation was associated with increased risk of 20 of 24 gastrointestinal diseases, including 7 upper gastrointestinal diseases (gastroesophageal reflux, esophageal cancer, gastric ulcer, duodenal ulcer, acute gastritis, chronic gastritis and gastric cancer), 4 lower gastrointestinal diseases (irritable bowel syndrome, diverticular disease, Crohn's disease and ulcerative colitis), 8 hepatobiliary and pancreatic diseases (non-alcoholic fatty liver disease, alcoholic liver disease, cirrhosis, liver cancer, cholecystitis, cholelithiasis, acute and chronic pancreatitis), and acute appendicitis. Fifteen out of 21 associations persisted after adjusting for genetically-predicted alcohol consumption. Genetically-predicted higher alcohol consumption was associated with increased risk of duodenal cancer, alcoholic liver disease, cirrhosis, and chronic pancreatitis; however, the association for duodenal ulcer did not remain after adjustment for genetic predisposition to smoking initiation. Conclusion: This study provides MR evidence supporting causal associations of smoking with a broad range of gastrointestinal diseases, whereas alcohol consumption was associated with only a few gastrointestinal diseases.

Birth weight, childhood body mass index, and risk of diverticular disease in adulthood.

International journal of obesity (2005) [Epub ahead of print].

OBJECTIVE: Adult overweight is associated with increased risk of diverticular disease (DD). We investigated associations between birthweight and childhood body mass index (BMI) and DD.

METHODS: Cohort study of 346,586 persons born during 1930-1996 with records in the Copenhagen School Health Records Register. Data included birthweight, and height and weight from ages 7 through 13. We used Cox proportional hazard regression to examine associations between birthweight and BMI z-scores and DD registered in the Danish National Patient Registry. Due to non-proportionality, we followed participants from age 18-49 and from age 50.

RESULTS: During follow-up, 5459 (3.2%) women and 4429 (2.5%) men had DD. For low and high BMI in childhood, we observed a higher risk of DD before age 50. Among women with z-scores <0 at age 13, the hazard ratio (HR) was 1.16 [95% confidence interval (CI): 0.98-1.39] per one-point lower z-score. For z-scores ≥0 at age 13, the HR was 1.30 (95% CI: 1.11-1.51) per one-point higher z-score. Among men with z-scores <0 at age 13, the HR was 1.02 (95% CI: 0.85-1.22). For z-scores ≥0 at age 13, the HR was 1.54 (95% CI: 1.34-1.78). Z-scores ≥0 were not associated with DD after age 50. Among women only, birthweight was inversely associated with DD before age 50 [HR = 0.90 (95% CI: 0.83-0.99) per 500 g higher birthweight].

CONCLUSION: BMI z-scores below and above zero in childhood were associated with higher risk of DD before age 50. In addition, we observed lower risk of DD among women, the higher their birthweight.

Faecalibacterium prausnitzii is not decreased in symptomatic uncomplicated diverticular disease of the colon.

Bioscience of microbiota, food and health, 42(1):1-2.

In this letter, assessment of the amount of fecal Faecalibacterium prausnitzii in symptomatic uncomplicated diverticular disease (SUDD) is described. Among 44 consecutive patients, comprising 15 SUDD patients, 13 patients with asymptomatic diverticulosis (AD), and 16 healthy controls (HC), the fecal amount of Faecalibacterium prausnitzii was not found to be significantly different between HC, AD and SUDD subjects (p=0.871). Moreover, its count in the HC microbiota (-4.57 ± 2.15) was lower compared with those in the AD (-4.11 ± 1.03) and SUDD subjects (-4.03 ± 1.299). This behavior seems to be different from that occurring in inflammatory bowel disease (IBD) and similar to that of other mucin-degrading species in a SUDD setting.

Management of Acute Uncomplicated Diverticulitis: Inpatient or Outpatient.

Sisli Etfal Hastanesi tip bulteni, 56(4):503-508.

OBJECTIVES: Diverticular disease is a highly frequent condition and affects 50% of the population in the 9th decade in Western society. Acute diverticulitis is the most prevalent complication. The patients who are clinically stable and tolerate fluid should be hospitalized if fluid intake tolerance worsens, fever occurs, or pain increases. Bowel rest, intravenous fluid therapy, and empiric antibiotic therapy are the traditional treatments for patients admitted to the hospital. This retrospective study aimed to determine the parameters that will affect the outpatient or inpatient treatment of patients diagnosed with uncomplicated acute diverticulitis.

METHODS: Patients who presented to the emergency department with abdominal pain between January 2018 and December 2020 and were diagnosed with uncomplicated diverticulitis (modified Hinchey 1a) on computed tomography (CT) taken after intravenous contrast material shoot up were included in the study. Patient records were recorded retrospectively in the Excel file. After being seen in the emergency department, a comparison was performed between the inpatient group (Group 1) and the outpatient follow-up group (Group 2).

RESULTS: The study comprised 172 patients with acute uncomplicated diverticulitis (modified Hinchey 1a). While 110 (64.0%) patients were followed up and treated as inpatients (Group 1), 62 (36.0%) patients were followed up as outpatients (Group 2). There was no statistically significant difference between the two groups in terms of patients readmitted to the hospital in the first 30 days after discharge (both for outpatient follow-up in the emergency department and after treatment in the inpatient group).

CONCLUSION: In this retrospective study, in which we evaluated the hospitalization criteria in uncomplicated Modified Hinchey 1a patients, it was found that patients can be safely treated as an outpatient if they have poor physical examination findings. Although there was no difference between the two groups in terms of hospital readmission after discharge and it was thought that follow-up of patients with Modified Hinchey 1a diverticulitis with outpatient oral antibiotic therapy might be reliable, prospective studies with larger numbers of patients are needed.

IATROGENIC URETEROCOLIC FISTULA IN PEDIATRIC AGE GROUP: A CASE REPORT AND REVIEW OF THE LITERATURE.

Ureteral injury is one of the major complications related to colorectal and gynaecologic procedures. Injuries are sometimes identified intraoperatively, but the diagnosis of ureteral injury is often delayed. Ureterocolic fistula is a relatively rare condition and mostly due to obstructing calculi, diverticular disease of the colon, radiotherapy, cancer, or trauma. Here in, we present a boy with an iatrogenic left ureterocolic fistula following multiple colonic surgeries that were complicated by an un-noticed left ureteric injury. This injury was not diagnosed early and the patient presented later with recurrent UTIs and decreased left differential renal function which necessitated open left nephroureterectomy.

Colonoscopic findings in patients with pelvic floor dysfunction.

ANZ journal of surgery [Epub ahead of print].

BACKGROUNDY: Colonoscopy is often performed in the initial workup of pelvic floor dysfunction, even in the absence of red flag symptoms. Current guidelines suggest colonoscopy is only required in the presence of rectal bleeding, diarrhoea or change in bowel habit. The aim of this study was to evaluate the prevalence of significant pathology found at colonoscopy in patients with pelvic floor dysfunction.

METHODS: Retrospective chart review was performed on all patients presenting to a functional colorectal outpatient clinic between May 2018 and August 2019. Information was collected on presenting symptoms, whether colonoscopy had been performed within 5 years, quality of bowel preparation, withdrawal time, number of polyps detected, histology, presence of diverticular disease, colorectal malignancy, inflammatory bowel disease, solitary rectal ulcer or rectal prolapse.

RESULTS: There were 260 patients seen within the study period, of which 67% had undergone recent colonoscopy within the last 5 years. The mean age was 53 and 219 (84%) patients were female. Average withdrawal time was 13 min. Polyps were found in 48.7% and adenomas in 32.4% of all colonoscopies. The adenoma detection rate was 32.7%. None of the colonoscopies found evidence of malignancy. A new diagnosis of inflammatory bowel disease was discovered in two patients.

CONCLUSION: There was low rates of serious pathology such as malignancy or inflammatory bowel disease in patients referred to a functional clinic. However, colonoscopy is still useful in workup of pelvic floor dysfunction, as many patients have erratic bowel habits or vague symptoms, and will have adenomas found.

Long-term functional outcome after tubular laparoscopic sigmoid resection for diverticular disease.

International journal of colorectal disease, 38(1):14.

PURPOSE: Sigmoid resection for diverticular disease is a frequent surgical procedure in the Western world. However, long-term bowel function after sigmoid resection has been poorly described in the literature. This study aims to assess the long-term bowel function after tubular sigmoid resection with preservation of inferior mesenteric artery (IMA) for diverticular disease.

METHODS: We retrospectively identified patients who underwent sigmoid resection for diverticular disease between 2002 and 2012 at a tertiary referral center in northern Germany. Using well-validated questionnaires, bowel function was assessed for fecal urgency, incontinence, and obstructed defecation. The presence of bowel dysfunction was compared to baseline characteristics and perioperative outcome.

RESULTS: Two hundred and thirty-eight patients with a mean age of 59.2 ± 10 years responded to our survey. The follow-up was conducted 117 ± 32 months after surgery. At follow-up, 44 patients (18.5%) had minor LARS (LARS 21-29) and 35 (15.1%) major LARS (LARS ≥ 30-42), 35 patients had moderate-severe incontinence (CCIS ≥ 7), and 2 patients (1%) had overt obstipation (CCOS ≥ 15). The multivariate analysis showed that female gender was the only prognostic factor for long-term incontinence (CCIS ≥ 7), and ASA score was the only preoperative prognostic factor for the presence of major LARS at follow-up.

CONCLUSION: Sigmoid resection for diverticular disease can be associated with long-term bowel dysfunction, even with tubular dissection and preservation of IMA. These findings suggest intercolonic mechanisms of developing symptoms of bowel dysfunction after disruption of the colorectal continuity that are so far summarized as "sigmoidectomy syndrome."

Feasibility and safety of a robotic approach to diverticular disease: a retrospective series of short-term outcomes.

ANZ journal of surgery [Epub ahead of print].

BACKGROUNDS: Robotic colorectal surgery is a method of performing complex surgery in a minimally invasive manner. In diverticular disease, chronic inflammation obscures tissues planes and increases difficulty of resection. This study aims to assess feasibility and safety of application of a robotic approach to diverticular disease, by reviewing short-term outcomes from a series of diverticular resections.

METHODS: Forty-one patients underwent robotic colorectal surgery for diverticular disease across three centres within Melbourne from June 2016 to June 2022. Demographic, operative, and clinicopathological data were collected. Descriptive statistics were used to evaluate primary and secondary outcomes. Comparative analysis between simple and complex diverticular disease was performed to identify differences in groups regarding short term outcomes. The primary outcome in this study is to determine conversion rate from minimally invasive to open surgery. Secondary outcomes include major complication rates and length of stay.

RESULTS: Of the 41 patients, 24 (58.5%) had simple disease, and 17 (41.5%) had complex disease. One patient (2.4%) required conversion to open resection. The median length of stay for complex disease was 7 days, for simple disease 5 days (P = 0.05). Four surgical Clavien-Dindo III or above complications occurred (9.8%), one patient required return to theatre. There were no anastomotic leaks or collections requiring radiological drainage. Thirteen patients (31.7%) underwent ureteric stenting and intraoperative indocyanine green dye ureteric identification.

CONCLUSION: Robotic diverticular resections in this series are safe and associated with a low conversion rate of 2.4%. Robotic resection of complex disease was feasible with an acceptable safety profile.

Anastomotic Considerations in Diverticulitis.

Clinics in colon and rectal surgery, 36(1):57-62.

Diverticulitis is a common indication for colorectal surgery, both in the acute and the elective setting. The anastomosis between the colon and rectum is a critical component of colectomy for diverticular disease and should be approached thoughtfully. This article reviews important surgical considerations when creating a colorectal anastomosis in the setting of diverticular disease, whether following the reversal of an end colostomy, during an acute episode of diverticulitis, or electively for chronic or complicated disease. Timing of surgery and preoperative assessment, minimally invasive approaches, and intraoperative maneuvers and considerations are discussed.

What's in a Number? Assessing the Burden of Diverticular Disease.

Annals of surgery open : perspectives of surgical history, education, and clinical approaches, 3(4):e202.

In this prospective observational cohort of patients with a history of diverticulitis, we assessed the correlation between the diverticulitis quality of life survey (DVQOL) and other patient-reported expressions of disease measures including work and activity impairment, and contentment with gastrointestinal-related health. Then, we assessed whether the DVQOL is better correlated with these measures than diverticulitis episode count. Our study results showed that the DVQOL has a stronger correlation with other disease measures than diverticulitis episode count, and our findings support the broader use of the DVQOL in assessing the burden of diverticulitis and monitoring response to management.

Increased accuracy in diagnosing diverticulitis using predictive clinical factors.

Upsala journal of medical sciences, 127:.

BACKGROUND: The aim of this study was to identify clinical factors leading to increased diagnostic accuracy for acute colonic diverticulitis.

METHODS: Patients with clinical suspicion of acute colonic diverticulitis verified with computed tomography (CT) from two hospitals in Sweden between 9 January 2017 and 31 October 2017 were prospectively included. Symptoms, comorbidities, and laboratory results were documented. Candidate variables were analyzed using logistic regression, and the final variable set that yielded the most accurate predictions was identified using least absolute shrinkage and selection operator regression and evaluated using the area under the receiver operating characteristic (ROC) curve.

RESULTS: In total, 146 patients were included (73% women; median age 68 years; age range, 50-94 years). The clinical diagnostic accuracy was 70.5%. In the multiple logistic regression analysis, gender (female vs male odds ratio [OR]: 4.82; confidence interval [CI], 1.56-14.91), age (OR, 0.92; 95% CI, 0.87-0.98), pain on the lower left side of the abdomen (OR, 15.14; 95% CI, 2.65-86.58), and absence of vomiting (OR, 14.02; 95% CI, 2.90-67.88) were statistically significant and associated with the diagnosis of CT-verified diverticulitis. With seven predictors (age, gender, urinary symptoms, nausea, temperature, C-reactive protein, and pain left lower side), the area under the ROC curve was 0.82, and a formula was developed for calculating a risk score.

CONCLUSION: We present a scoring system using common clinical variables that can be applied to patients with clinical suspicion of colonic diverticulitis to increase the diagnostic accuracy. The developed scoring system is available for free of charge at https://phille-wagner.shinyapps.io/Diverticulitis_risk_model/.

Ureteral identification with indocyanine green in laparoscopic colorectal surgery.

Asian journal of endoscopic surgery [Epub ahead of print].

INTRODUCTION: Fluorescence-guided surgery has emerged as a complement of traditional laparoscopic surgery with the advantage that is adaptable to existent platforms. The purpose of this article is to describe our technique for ureteral identification with indocyanine green (ICG) during laparoscopic colorectal surgery.

We report a case series of all patients who underwent laparoscopic colorectal surgery and ureteral injection of ICG in a private third level hospital.

RESULTS: We performed 30 laparoscopic colorectal surgeries in which we used this technique to identify the ureters. Mean age was 52.6 ± 15.28 years; 16 (53.3%) were men. The indication for surgery was diverticulitis in 18 patients. Mean urological operative time was 22.4 minutes. There were no immediate or delayed adverse effects attributable to intra-ureteral ICG administration.

DISCUSSION: Although ureteric iatrogenic injury is uncommon, when it does happen, it significantly increases the patient's morbidity. We consider this technique has the potential to make laparoscopic surgeries safer mostly in patients with cancer, diverticular disease or endometriosis who have extensive fibrosis, adhesions, and inflammation.

Mesh Migration and Bowel Perforation as a Late Complication of Transabdominal Preperitoneal Laparoscopic Hernia Repair.

Cureus, 14(12):e32683.

Minimally invasive surgery is increasingly used in the treatment of inguinal hernias, with two main techniques described: transabdominal preperitoneal (TAPP) and totally extraperitoneal (TEP). In both techniques, a prosthetic mesh is placed in a preperitoneal position. However, in TAPP, the peritoneum flap must be completely closed. The TAPP technique is associated with more intra-abdominal complications. This article describes a case of bowel occlusion due to migration and erosion of a mesh after a TAPP repair in a 57-year-old patient with a history of colonic diverticular disease. The patient complained of abdominal discomfort and constipation, having undergone a colonoscopy and CT scan that demonstrated the presence of a foreign body partially in the lumen of the sigmoid colon. The treatment was surgical, with bowel resection and partial removal of the mesh, complicated by a deep tissue collection. The patient maintained follow-up in a surgery consultation, with no evidence of hernia recurrence. This is a rare complication of the laparoscopic approach in the treatment of inguinal hernia, more frequent in the TAPP technique. It is intended to draw attention to the type of closure of the peritoneum.

Microbiota of the Colonic Diverticula in the Complicated Form of Diverticulitis: A Case Report.

Life (Basel, Switzerland), 12(12):.

Intestinal microbiota appears to be implicated in the pathogenesis of diverticular disease. We present the case of a patient with diverticular colon disease complicated by a pelvic abscess. During the successful surgical treatment, two specimens were taken from the resected colon segment for the microbiota analysis: an inflamed and perforated diverticulum and a diverticulum without signs of inflammation. Culturing and 16S rRNA gene sequencing revealed significant changes in the microbial community structure and composition associated with the acute inflammation and perforation of the colonic diverticulum. The characteristics that are usually associated with the inflammatory process in the gut, namely reduced microbial diversity and richness, decreased Firmicutes-to-Bacteroidetes (F/B) ratio, depletion of butyrate-producing bacteria, and Enterobacteriaceae blooming, were more pronounced in the non-inflamed diverticulum rather than in the adjacent inflamed and perforated one. This is the first study of the intraluminal microbiota of the diverticular pockets, which is more relevant to the etiology of diverticular disease than mucosa-associated microbiota via biopsies and luminal microbiota via fecal samples.

Hartmann's Reversal: A Single-Centre Experience.

Cureus, 14(11):e31654.

A proctosigmoidectomy, commonly called Hartmann's procedure (HP), is the surgical resection of the rectosigmoid colon with the closure of the anorectal stump and creation of an artificial stomal opening (ostomy) on the abdomen (colostomy). It is generally performed with the intention of reversal once the underlying cause is treated. The aim of this study is to assess the predictive factors and intra-operative difficulties that might influence the decision to indicate or contra-indicate stomal reversal after HP. Patients who underwent HP between January 2010 and December 2017 were retrospectively evaluated in a single institution. Preoperative, intraoperative, and postoperative data were analysed for patients who underwent HP for benign as well as malignant conditions. The reversal rate was comparable with the proportion of benign cases, consistent with published evidence that reversal rates for diverticular disease are higher as compared to colorectal cancer. Disease progression/metastasis, advanced age, multiple co-morbidities, and procedure abandonment (frozen pelvis /leak) were the most common contra-indications for reversal.

Yield of Post-Acute Diverticulitis Colonoscopy for Ruling Out Colorectal Cancer.

Techniques and innovations in gastrointestinal endoscopy, 24(3):254-261.

BACKGROUND AND AIMS: Colonoscopy is recommended post-acute diverticulitis (AD) to exclude underlying adenocarcinoma (CRC). However, post-AD colonoscopy utility remains controversial. We aimed to examine yield of post-AD colonoscopy in our majority-Hispanic patient population.

METHODS: Patients undergoing post-AD colonoscopy between 11/1/2015-7/31/2021 were identified from a prospectively maintained endoscopic database. AD cases without computed tomography confirmation were excluded. Pertinent data, including complicated vs uncomplicated AD, fecal immunochemical test (FIT) result post-AD/pre-colonoscopy, and number/type/location of non-advanced adenomas, advanced adenomas, and CRC, were abstracted. Analyses were conducted using two-sample Wilcoxon rank-sum and Fisher's exact tests.

RESULTS: 208 patients were included, of whom 62.0% had uncomplicated AD. Median age was 53, 54.3% were female, and 77.4% were Hispanic. Ninety non-advanced adenomas were detected in 45 patients (21.6%), in addition to advanced adenoma in eight patients (3.8%). Two patients (1.0%) had CRC, both of whom had complicated AD in the same location seen on imaging, and one of whom was FIT+ (the other had not undergone FIT). Patients with uncomplicated versus complicated AD had similarly low rates of advanced adenomas (4.7% vs. 2.5%, p=0.713). FIT data were available in 51 patients and positive in three (5.9%); non-advanced adenomas were found in all three FIT+ patients. No FIT- patient had an advanced adenoma or CRC.

CONCLUSION: Colonoscopy post-AD is generally low yield, with CRC being rare and found only in those with complicated AD. Colonoscopy post-complicated AD appears advisable, whereas less invasive testing (e.g. FIT) may be considered post-uncomplicated AD to inform the need for colonoscopy.

The Characteristics of Diverticular Disease in Caribbean Population: A Control Group Study.

Canadian journal of gastroenterology & hepatology, 2022:8360837.

BACKGROUND: Diverticulosis is not well characterized in the Caribbeans. Our aim was to compare the anatomical presentation of colonic diverticulosis in African Caribbeans (group AC) versus Europeans (group E) and severity.

METHODS: We conducted a prospective controlled study involving 274 patients admitted for lower gastrointestinal haemorrhage (LGIH) in France (center 1: Guadeloupe; center 2: La Roche-sur-Yon); 179 cases with diverticular haemorrhage, including 129 in group AC and 40 in group E. Exploration of the colon included a detailed assessment of diverticula using a dedicated endoscopic grid.

RESULTS: AC and E had similar characteristics in terms of age, gender, previous history of LGIH, body mass index, dietary habits, and medications, but AC had significantly poorer hemodynamic parameters at admission and required more blood transfusions (66.7% vs. 42.5%; p=0.01) during hospitalization. Out of the 169 patients included in the study, a complete exploration of the colon was achieved in 81% (N = 137) (AC, n = 106; E, n = 31), and revealed right-side diverticulosis in AC (in 90.6%, included into a pancolonic form in 73.6% vs. 35.5%; p=0.0002) and left-side diverticulosis in E (in 96.8%, isolated form in 58.1% vs. 9.4%, p=0.0002). These data were confirmed by a sensitivity analysis using an endoscopic grid in 92 patients, achieving a higher frequency and larger size of diverticula in AC.

CONCLUSION: Our study has shown that diverticulosis was pancolonic in AC and more frequently associated with more severe haemorrhage than the left-sided diverticulosis of Europeans. This anatomical presentation may be driven by the genetic background more than the environment and diet.

Secondary Aorto-Colonic Fistula: A Case Report and Literature Review of a Rare Complication after EVAR.

Case reports in surgery, 2022:8412460.

Background: Aorto-enteric fistula (AEF) is a rare but fatal condition. The incidence of the overall AEF was approximately 0.36-2%, but the incidence of the aorto-colonic fistula was scarcely reported. A history of abdominal pain, fever, or gastrointestinal bleeding (GIB) in a patient with a history of aortic intervention should be highly suspected of this condition. This report describes a patient with lower GIB after an endovascular aneurysm repair (EVAR) for a symptomatic abdominal aortic aneurysm (AAA). Case Presentation: A 65-year-old man with a history of EVAR for symptomatic AAA presented with a massive lower GIB for two weeks. He also had a history of left lower quadrant pain and low-grade fever. Diverticular disease was suspected, and medical treatment was administered. After the initial conservative treatment, a colonoscopy was performed. The findings showed a fistula that exposed an aortic stent graft at the left-sided colon. An aorto-colonic fistula was diagnosed. After administering intravenous (IV) antibiotics, a staged axillo-bifemoral bypass graft with aortic stent graft explantation was performed. The patient recovered well and was discharged home after a month of hospitalization and IV antibiotics. Conclusion: In a patient with a history of aortic intervention, any abdominal pain, unknown fever, or even GIB should be suspected of complications of aortic intervention. Highly suspicious of this rare condition is the key to an early diagnosis and prompt treatment.

[Diverticular disease: treatment and management by general practitioners in Germany - high importance of probiotics in primary care].

MMW Fortschritte der Medizin, 164(Suppl 8):16-26.

INTRODUCTION: The symptomatic uncomplicated diverticular disease (SUDD) is often difficult to treat and guidelines only provide few evidence-based treatment options.

METHOD: For the German-wide survey, a questionnaire was sent to 13790 physicians. It contained questions concerning the status of medical care for patients with diverticula and queried their individual option in regards to current treatment options and challenges for the daily medical routine.

RESULTS: In total, 526 questionnaires were sent back for analysis. The biggest challenge for doctors handling patients with chronic diverticular disease (SUDD) is to make the correct diagnosis (17%) and the distinction to the irritable bowel syndrome (22%). Despite the high abundance of SUDD pathology, only 6% of the medical practitioners feel themselves sufficiently informed about it. The support for general practitioners by medical specialists (gastroenterologists) is limited: In the case of a SUDD or a diverticulitis diagnosis, the physicians sometimes receive an acute therapy plan (27%), but rarely get recommendations for diverticulitis pre- and post-care (11% and 18%), or assisting information for patient education (4%). For primary prophylaxis for persons with asymptomatic diverticula, practitioners give nutrition (41%) and life style (37%) recommendations, as well as probiotics (18%). After an acute diverticulitis, 42% recommend life style and nutrition modifications and 26% the intake of probiotics. For the treatment of SUDD symptoms, they advise mostly life style and nutrition modifications (45%) and probiotics (30%). About 60% of the doctors are satisfied with the efficacy of probiotics. Another 15% stated that they have not yet used them to treat SUDD. The main reasons for it seem to be the lack of reimbursability for probiotics (31%), the poor adherence of patients to therapy (20%) due to the slow onset of positive effects, and the difficulty of finding an evidence-based probiotic (16%).

CONCLUSION: In the daily medical routine the correct diagnosing of SUDD is a major challenge and supporting information by medical specialist is scarce. Physicians frequently choose life style and nutrition recommendations and the use of probiotics as treatment options. The majority of the general practitioners is thereby satisfied with the efficacy of probiotics for patients with chronic diverticular disease, even though the choice of an evidence-based probiotic is an obstacle.

Microbiota Composition in Diverticular Disease: Implications for Therapy.

International journal of molecular sciences, 23(23): pii:ijms232314799.

Gut microbiota (GM) composition and its imbalance are crucial in the pathogenesis of several diseases, mainly those affecting the gastrointestinal tract. Colon diverticulosis and its clinical manifestations (diverticular disease, DD) are among the most common digestive disorders in developed countries. In recent literature, the role of GM imbalance in the onset of the different manifestations within the clinical spectrum of DD has been highlighted. This narrative review aims to summarize and critically analyze the current knowledge on GM dysbiosis in diverticulosis and DD by comparing the available data with those found in inflammatory bowel disease (IBD). The rationale for using probiotics to rebalance dysbiosis in DD is also discussed.

Metronidazole and Peripheral Neuropathy: A Report of Two Cases of (Unusual) Side Effects.

Cureus, 14(10):e30889.

Metronidazole is an antibiotic commonly prescribed for anaerobic and protozoan infections. Despite its good safety profile, this drug frequently causes a series of well-known side effects (nausea and intestinal transit disorders, dysgeusia, headaches, and alcohol intolerance). However, there are few data in the literature, mainly case reports and case series, about the onset of peripheral neuropathy with a generally self-limiting course after drug withdrawal. Thus, we herein describe two cases of peripheral neuropathy due to treatment with metronidazole. A 69-year-old woman treated with a total of 55 g of metronidazole for diverticular disease and a 52-year-old male patient on a long course of antibiotic therapy for hepatic abscesses (a cumulative dose of 168 g) developed peripheral neuropathy. The suspicion of metronidazole side effects was raised after the exclusion of other causes. After the suspension of the drug, different degrees of improvement were observed. Metronidazole is an effective antibiotic for treating infections caused by anaerobic or protozoan pathogens, and it has a good pharmacological and economic safety profile. However, in the existing literature, prolonged therapy regimens (>4 weeks of treatment and/or 42 g cumulative dose) may increase the risk of developing neurological complications, in particular peripheral polyneuropathy.

German guideline diverticular disease/diverticulitis: Part II: Conservative, interventional and surgical management.

United European gastroenterology journal [Epub ahead of print].

Diverticulosis and diverticular disease are ranked among the most common gastroenterological diseases and conditions. While for many years diverticulitis was found to be mainly an event occurring in the elder population, more recent work in epidemiology demonstrates increasing frequency in younger subjects. In addition, there is a noticeable trend towards more complicated disease. This may explain the significant increase in hospitalisations observed in recent years. It is not a surprise that the number of scientific studies addressing the clinical and socioeconomic consequences in the field is increasing. As a result, diagnosis and conservative as well as surgical management have changed in recent years. Diverticulosis, diverticular disease and diverticulitis are a complex entity and apparently an interdisciplinary challenge. To meet theses considerations the German Societies for Gastroenterology and Visceral Surgery decided to create joint guidelines addressing all aspects in a truely interdisciplinary fashion. The aim of the guideline is to summarise and to evaluate the current state of knowledge on diverticulosis and diverticular disease and to develop statements as well as recommendations to all physicians involved in the management of patients with diverticular disease.

Metastatic Hepatocellular Carcinoma Masquerading as Acute Diverticulitis.

ACG case reports journal, 9(11):e00913.

Colorectal cancer may masquerade as acute diverticulitis. Our case is a 71-year-old man who presented to the emergency department with abdominal pain and was diagnosed with acute diverticulitis. He was ultimately found to have metastatic hepatocellular carcinoma to the colon without any evidence of diverticular disease on colonoscopy. Although the most common malignancy to masquerade as diverticulitis is colorectal cancer, metastatic deposits should also be considered, especially in patients with a history of extracolonic malignancy.

Diverticulitis and Diverticulosis of the Appendix: A Case Series.

Cureus, 14(10):e30786.

Introduction Diverticula of the appendix is a rare entity, may be complicated by inflammation/infection, and clinically mimics acute appendicitis. The reported associated risk factors include male gender, Hirschprung's disease, cystic fibrosis and adult age, where some reports claim that they are also associated with an increased risk of appendiceal malignancy. Imaging has a place in pre-operative diagnosis, however, most of the cases were diagnosed during a pathological examination after surgery. They are associated with a higher rate of perforation (more than four times compared with classical acute appendicitis). In this review, we present a case series of five patients diagnosed with diverticulitis and one with diverticulosis of the appendix that were managed at a single centre. Our aim is to explore the common clinical, radiological, and intra-operative findings associated with this disease as well as the outcome of management. Materials and methods A total number of six cases of diverticular disease of the appendix diagnosed and managed at Basildon University hospital in the period between 2016 and 2020 were studied. The demographic details and clinical data including presenting symptoms, laboratory results, radiological characteristics, intraoperative findings and histopathological features were analysed. Results The study group included four males and two females, with an age range of 20-84 years. The most common presenting clinical symptoms were right iliac fossa abdominal pain, nausea, anorexia, and diarrhoea. Half of the cases showed a thickened appendix in the pre-operative CT scan. An inflamed or perforated appendix was seen in five cases as well as inflammation of the diverticula. Conclusion Appendiceal diverticulitis is an uncommon pathology that imitates acute appendicitis, and appendicectomy is the standard treatment. Prophylactic appendicectomy is recommended for non-inflamed diverticula - this is due to the potential risk of inflammation, perforation, and the risk of developing an appendiceal neoplasm.

Laparoscopic Welti's Maneuver: A Single-Center Experience.

Journal of laparoendoscopic & advanced surgical techniques. Part A [Epub ahead of print].

Purpose: Left hemicolectomy is the standard surgical operation for a variety of colonic diseases, both benign and malignant. When colonic resection is extended, relocation of the small bowel loops can be difficult. Several techniques have been described to reposition the small intestine. Welti's technique consists in the passage of the entire small bowel to the left side of the abdomen, below the descending colon that is positioned on the right side. Methods: We retrospectively evaluated 23 patients who underwent extended left hemicolectomy and reconstruction according to the Welti's technique at our hospital. We assessed the recovery of intestinal function and the length of hospital stay; in the mid-term follow-up we searched for episodes of acute or chronic intestinal obstruction. Results: Median operative time was 215 minutes; median resumption of gas and stool emission were, respectively, 3 days (interquartile range [IQR]: 2-6) and 4 days (IQR: 2-9) after surgery. Median hospital stay was 8 (IQR: 5-37) day. After a median follow-up of 15 months (IQR: 3-132) we did not observe any episode of acute or chronic bowel obstruction. Conclusions: Welti's technique is safe and does not cause a delay in resumption of bowel functions or a delayed hospital discharge; it is a useful technique that the colorectal surgeon can use when needed.

Diverticulitis during pregnancy: A review of the reported cases.

Frontiers in medicine, 9:942666.

BACKGROUND: Diverticular disease of the colon represents a common clinical condition in the western world. Its prevalence increases with age and only 5% of cases occur in adults younger than 40 years of age, making it a rare condition during pregnancy. The aim of this review was to provide an overview of the reported cases of diverticulitis during pregnancy.

METHODS: We conducted a systematic review of the literature based on preferred reporting items for systematic review and meta-analysis (PRISMA) guidelines. We searched three different electronic databases namely PubMed, Scopus and Web of Science from inception to December 2021. Literature search and data extraction were completed in duplicates.

RESULTS: The initial search yielded 564 articles from which 12 were finally included in our review. Ten articles were case reports and two were observational studies. The mean age of the cases was 34 years. The presenting complain was provided for 11 cases. The majority of the patients (10/11, 91%) presented with abdominal pain located mainly on the left (6/11, 55%) or right (4/11, 36%) iliac fossa. The most common diagnostic modality used for the diagnosis of the condition was ultrasonography in nine cases (9/12, 75%) followed by magnetic resonance imaging (MRI) in two cases (2/12, 17%). In spite of clinical and radiological evaluation, the initial diagnosis was inaccurate in seven cases (7/12, 58%). The therapeutic approach was available for 11 cases and it was based on the administration of intravenous antibiotics in six cases (6/11, 55%) and surgical management in five cases (5/11, 45%). Data for the type of delivery was provided in nine studies with five patients (5/9, 56%) delivering vaginally and four patients (4/9, 44%) delivering with cesarean section.

CONCLUSION: As advanced maternal age becomes more common, the frequency of diverticulitis in pregnancy may increase. Although available guidelines do not exist, the clinical awareness, early recognition of the disorder, using diagnostic modalities such as ultrasound and MRI, and rapid therapeutic approach with antibiotics, may improve maternal and neonatal outcomes.

Right-sided colopleural fistula secondary to diverticular disease: a case report.

Journal of medical case reports, 16(1):442.

BACKGROUND: Colopleural fistulas are mostly left-sided and related to trauma, Crohn's disease, or gastrointestinal malignancy. However, a diverticular fistula between the colon and right pleural space has not been reported and is rare considering the liver forms a natural anatomical barrier on this side. Colopleural fistulas often present with respiratory symptoms ranging from mild cough and dyspnea to sepsis from empyema caused by the leakage of gastrointestinal content into the pleural space. Although colopleural fistulas are rare, maintaining low suspicion is pivotal for timely investigation and appropriate surgical planning, particularly in the context of previous intra-abdominal infections or trauma.

CASE PRESENTATION: A 67-year-old Chinese male presenting with prolonged respiratory symptoms was found to have a right-sided colopleural fistula confirmed by computed tomography imaging and a colonoscopy. It was addressed surgically after multidisciplinary consensus was reached, with a right hemicolectomy and repair of the diaphragmatic defect. The patient recovered remarkably well with resolution of respiratory symptoms.

CONCLUSION: Appropriate work-up of a suspected colopleural fistula with radiological and endoscopic investigations to determine anatomy and etiology is crucial. Most cases will require surgical management, and involvement of the respiratory and cardiothoracic teams is important to optimize lung function preoperatively and plan for possible chest complications.

Colovesical Fistula: An Uncommon Cause of Hematuria and Rectal Bleeding.

Case reports in gastrointestinal medicine, 2022:1419250.

Colovesical fistula is an infrequent complication of diverticular disease that presents with pneumaturia, fecaluria, dysuria and, rarely, hematuria or hematochezia. Here we present a case of concurrent hematuria and rectal bleeding arising from a diverticular bleed traversing a previously undiagnosed colovesical fistula. Other causes of colovesical fistula include Crohn's disease, radiation, and malignancy, though it is most commonly caused by complicated diverticulitis as in this case. Computed tomography (CT) imaging, cystoscopy, and gastrograffin enema have been described as high-yield diagnostic tests. Interestingly, colonoscopy is only successful in diagnosing colovesical fistula in approximately 55% of cases. Management often requires surgical intervention, as in this case, given limited success with conservative management. Colovesical fistula should be considered in patients presenting with fecaluria, pneumaturia, and dysuria as well as in cases of hematuria.

How to manage lower gastrointestinal bleeding in 2022?.

Journal of visceral surgery, 159(6):486-496.

Lower gastrointestinal bleeding (LGIB), originating mainly in the colon, rectum and anus, occurs most often in older patients (7th decade) with co-morbidity, half of whom have coagulation abnormalities due to anti-coagulant or anti-aggregant therapy. In three cases out of four, bleeding regresses spontaneously but can recur in up to one third of patients. The main causes are diverticular disease, vascular disorders (hemorrhoids, angiodysplasia) and colitis. Ten to 15% of patients present in hypovolemic shock. The main problem is to determine the precise location and etiology of bleeding. First-line steps include correction of hemodynamics, correction of coagulation disorders and transfusion, as necessary. Rectal digital examination allows differentiation between melena and hematochezia. In patients with severe LGIB, upper endoscopy can eliminate upper gastro-intestinal bleeding (UGIB). Computerized tomography (CT) angiography can pinpoint the source. If contrast material extravasates, the therapeutic strategy depends on the cause of bleeding and the general status of the patient: therapeutic colonoscopy, arterial embolization and/or surgery. In the absence of severity criteria (Oakland score≤10), ambulatory colonoscopy should be performed within 14 days. Discontinuation of anticoagulant and/or antiplatet therapy should be discussed case by case according to the original indications.

Hartmann's procedure versus primary anastomosis for Hinchey stage III diverticulitis: a prospective case-control study.

Revista de gastroenterologia de Mexico (English), 87(4):509-512.

INTRODUCTION: Hartmann's procedure (HP) is the conventional treatment in patients with complicated diverticulitis. Segmental resection with primary anastomosis (PA) is a treatment alternative for those patients. Our aim was to compare the postoperative results of HP and PA in patients with complicated diverticulitis (Hinchey stage III).

METHODS: A case-control study was conducted on patients operated on for purulent Hinchey stage III diverticulitis, within the time frame of 2000 and 2019.

RESULTS: Twenty-seven patients that underwent PA were compared with 27 that underwent HP. The patients that underwent HP had a greater probability of morbidity at 30 days (OR 3.5; 95% CI 1.13-11.25), as well as a greater probability of major complications (OR 10.9; 95% CI 1.26-95.05).

CONCLUSION: The patients that underwent segmental resection and PA presented with lower morbidity rates and higher stoma reversal rates than the patients that underwent HP.

A National Inpatient Sample Analysis of Racial Disparities After Segmental Colectomy for Inflammatory Colorectal Diseases.

The American surgeon [Epub ahead of print].

BACKGROUND: Racial disparities and poor access to care are common among African Americans (AA), potentially adversely affecting surgical outcomes in inflammatory bowel conditions. We aimed to analyze the effect of race on outcomes in patients undergoing segmental colectomy for inflammatory bowel conditions.

METHODS: Retrospective review of data from the National Inpatient Sample between 2010 and 2015 identified patients who underwent segmental colectomy without ostomy for Crohn's or diverticular disease. AA patients were compared with Caucasians using a multivariable analysis model. Primary outcomes of interest were overall complications, mortality, and extended hospital stay.

RESULTS: 38,143 admissions were analyzed; AA patients constituted 8% of the overall cohort. Diagnoses included Crohn's (11%) and diverticular disease (89%). After multivariable analysis, AA patients had significantly higher overall risk of complications (OR = 1.27; 95% CI, 1.15-1.40) and extended hospital stay (OR = 1.59; 95% CI, 1.45-1.75) than Caucasians. On bivariate analysis, there was no significant difference in mortality between AA and Caucasian patients. AA patients had significantly higher rates of Medicaid insurance (14% vs 6%, P < .001), lower rates of private insurance (35% vs 47%, P < .001), and were less likely to undergo surgery at a private hospital (31% vs 41%, P < .001).

CONCLUSIONS: AA patients requiring segmental colectomy for inflammatory colorectal conditions experience significantly higher rates of postoperative complications, longer hospital stays, and lower rates of private insurance. Direct correlation between insurance status and postoperative outcomes could not be established, but we speculate such great disparity in outcomes may stem from these socioeconomic differences.

Muscle mass and quality as predictors for complications, recurrence and length of hospital stay in acute uncomplicated diverticulitis: a retrospective cohort study.

Scandinavian journal of gastroenterology [Epub ahead of print].

OBJECTIVES: The aim of this study was to investigate the potential correlation between muscle mass/muscle quality and risk of complications or recurrence in patients presenting with acute uncomplicated diverticulitis. It was also to study if low muscle mass/quality correlated to prolonged hospital stay.

MATERIALS AND METHODS: The study population comprised 501 patients admitted to Helsingborg Hospital or Skåne University Hospital between 1 January 2015 and 31 December 2017, who had been diagnosed with acute uncomplicated diverticulitis and undergone computed tomography upon admission. The scans were used to estimate skeletal muscle mass and muscle radiation attenuation (an indicator for muscle quality). Skeletal muscle index was obtained by adjusting skeletal muscle mass to the patients' height. Values of below the fifth percentile of a normal population were considered low.

RESULTS: There were no differences between the patients with normal versus those with low skeletal muscle mass, skeletal muscle index or muscle radiation attenuation regarding risk of complications or recurrence of diverticular disease. However, as only 11 patients had complications, no conclusion as to a potential correlation can be made. Low muscle quality correlated to longer hospital stay, also when adjusting for other potential confounders.

CONCLUSIONS: Muscle mass/quality do not seem to serve as predictor of risk for recurrent disease in patients with acute uncomplicated diverticulitis. However, low muscle radiation attenuation was associated with prolonged hospital stay. This indicates that muscle quality, assessed by computed tomography scan, might be used in clinical practise to identify patients at risk of longer hospitalisation.

When to Perform a Colonoscopy in Diverticular Disease and Why: A Personalized Approach.

Journal of personalized medicine, 12(10):.

Colonoscopy is a crucial diagnostic tool in managing diverticular disease (DD). Diverticulosis can often be an unexpected diagnosis when colonoscopy is performed in asymptomatic subjects, generally for colorectal cancer screening, or it could reveal an endoscopic picture compatible with DD, including acute diverticulitis, in patients suffering from abdominal pain or rectal bleeding. However, alongside its role in the differential diagnosis of colonic diseases, particularly with colon cancer after an episode of acute diverticulitis or segmental colitis associated with diverticulosis, the most promising use of colonoscopy in patients with DD is represented by its prognostic role when the DICA (Diverticular Inflammation and Complication Assessment) classification is applied. Finally, colonoscopy plays a crucial role in managing diverticular bleeding, and it could sometimes be used to resolve other complications, particularly as a bridge to surgery. This article aims to summarize "when" to safely perform a colonoscopy in the different DD settings and "why".

Mortality risk increased in colonic diverticular disease: a nationwide cohort study.

Annals of epidemiology, 76:39-49.

INTRODUCTION: There are limited population cohort data on overall and cause-specific mortality in colonic diverticular disease.

OBJECTIVE: To measure overall and cause-specific mortality in colonic diverticular disease, compared to matched reference individuals and siblings.

METHODS: Population-based cohort study ("the ESPRESSO study") in Sweden. There were 97,850 cases with a medical diagnosis of diverticular disease (defined by international classification of disease codes) and colorectal histology identified in 1987-2017 from histopathology reports. The mortality risk between individuals with colonic diverticular disease and matched reference individuals (n = 453/634) from the general population was determined. Cox regression models adjusted for comorbidity estimated hazard ratios (HRs) for all-cause mortality.

RESULTS: During follow-up, there were 32,959 deaths in individuals with colonic diverticular disease (44/1000 person-years) compared with 127,153 in matched reference individuals (34/1000 person-years), resulting in an HR of 1.27 (95%CI 1.25-1.29). Also compared to siblings, colonic diverticular disease patients were at increased risk of death, HR 1.39 (95%CI 1.33-1.45). Mortality risks were further increased in colonic diverticular disease patients with a colorectal biopsy showing any mucosal inflammation HR 1.36; (95%CI 1.33-1.38), with the most significant increase during the first year after diagnosis HR 2.18; (95%CI 2.05-2.32).

CONCLUSIONS: Mortality in colonic diverticular disease is increased over reference individuals in the general population. The presence of mucosal inflammation on colorectal biopsies is a predictor of increased risk of mortality.

Ileocolic Thrombophlebitis and Lymphadenitis Mimicking Acute Appendicitis as a Late Manifestation in a COVID-19 Patient: A Case Report.

Cureus, 14(9):e29019.

Coronavirus disease 2019 (COVID-19) is an infectious viral disease, manifesting primarily as a lung infection with fever and respiratory symptoms. However, it also has a wide range of gastrointestinal symptoms, including nausea, vomiting, abdominal pain, and diarrhea. Right lower quadrant (RLQ) abdominal pain is a common complaint for patients seeking care at emergency departments. In addition to appendicitis, the other possible causes include diverticular disease, epiploic appendagitis, Crohn's disease, or mesenteric lymphadenitis, among others. Mesenteric ischemia is an uncommon, but crucial cause of abdominal pain, necessitating early diagnosis and treatment. Herein, we report a 47-year-old man who presented to our emergency department complaining of RLQ abdominal pain following recovery from COVID-19. CT was performed due to concern for acute appendicitis. However, mesenteric thrombophlebitis and lymphadenitis in the ileocolic branch were noted on CT. His abdominal pain improved after receiving anticoagulation therapy. This case describes an uncommon etiology of RLQ abdominal pain that should be considered as a late complication of COVID-19.

Time Trend and Association of Early-Onset Colorectal Cancer with Diverticular Disease in the United States: 2010-2021.

Cancers, 14(19):.

PURPOSE: To examine time trends of incidence rates of EOCRC from 2010 to 2021 among patients with and without diverticular disease and to examine whether diverticular disease is associated with increased risk of EOCRC.

METHODS: This is a retrospective cohort study of 46,179,351 young adults aged 20-49, including 298,117 with diverticular disease. We examined yearly incidence rate of first diagnosis of EOCRC from 2010 through 2021 among patients with and without diverticular disease. The 5-year risk of EOCRC among patients with pre-existing diverticular disease was compared to propensity-matched patients without diverticular disease and EOCRC and odds ratio (OR) and 95% confidence interval (CI) were calculated.

RESULTS: The yearly incidence rate of new diagnosis of EOCRC (measured as new cases per 100,000 people per year) in young adults with pre-existing diverticular disease increased from 100 in 2010 to 402 in 2021, 4-6 times higher than in those without diverticular disease (24 in 2010 to 77 in 2021) (p < 0.001). Patients with diverticular disease were at higher risk for EOCRC than those without (OR: 1.76, 95% CI: 1.40-2.32).

CONCLUSION: The incidence of EOCRC continuously increased from 2010 through 2021 in patients with and without diverticular disease and was 4-6 times higher among patients with diverticular disease. Patients with pre-existing diverticular disease were at a significantly increased risk for EOCRC.

Which factors influence the decision to perform Hartmann's reversal in various causative disease situations? A retrospective cohort study between 2006 and 2021.

Colorectal disease : the official journal of the Association of Coloproctology of Great Britain and Ireland [Epub ahead of print].

AIM: Our aim was to investigate the predictive factors for Hartmann's reversal and to describe the differences in the rates and timings of Hartmann's reversal for various causative diseases.

METHOD: In this multicentre retrospective cohort study patients who underwent Hartmann's procedure (HP) between 2006 and 2018 were enrolled. To describe the demographic patterns of Hartmann's reversal through to 2021, we analysed the cumulative incidence rate of Hartmann's reversal over time based on the Kaplan-Meier failure estimate. Multivariable Cox proportional hazard analysis was performed with cluster-adjusted robust standard errors to calculate hazard ratios (HRs) for the assessment of variables associated with colostomy reversal.

RESULTS: Of 250 patients who underwent the index HP and survived to discharge, 112 (45%) underwent subsequent Hartmann's reversal (36% for malignant and 51% for benign disease). The causative diseases with the highest probability of colostomy reversal were trauma (85%) and diverticular disease (73%). Conversely, colostomy reversal was performed in only 16% for colonic volvulus and 17% for bowel ischaemia. Home discharge after index HP (HR 5.22, 95% CI 3.31-8.23) and a higher body mass index (HR 1.03, 95% CI 1.01-1.04) were associated with a higher probability of Hartmann's reversal, whereas older age, malignant disease and a history of cardiovascular and psychoneurological diseases were independently associated with a lower probability of colostomy reversal.

CONCLUSION: The probability and timing of Hartmann's reversal varied considerably with the surgical indications for colostomy creation. Our results could help surgeons counsel patients and their families regarding stoma closure surgery to set realistic expectations.

The optimal timing of elective surgery in sigmoid diverticular disease: a meta-analysis.

Langenbeck's archives of surgery, 407(8):3259-3274.

PURPOSE: The aim of this meta-analysis was to investigate the optimal time point of elective sigmoidectomy regarding the intraoperative and postoperative course in diverticular disease.

METHODS: A comprehensive literature research was conducted for studies comparing the operative outcome of early elective (EE) versus delayed elective (DE) minimally invasive sigmoidectomy in patients with acute or recurrent diverticular disease. Subsequently, data from eligible studies were extracted, qualitatively assessed, and entered into a meta-analysis. By using random effect models, the pooled hazard ratio of outcomes of interest was calculated.

RESULTS: Eleven observational studies with a total of 2096 patients were included (EE group n = 828, DE group n = 1268). Early elective sigmoidectomy was associated with a significantly higher conversion rate as the primary outcome in comparison to the delayed elective group (OR 2.48, 95% CI 1.5427-4.0019, p = 0.0002). Of the secondary outcomes analyzed only operative time (SMD 0.14, 95% CI 0.0020-0.2701, p = 0.0466) and time of first postoperative bowel movement (SMD 0.57, 95% CI 0.1202-1.0233, p = 0.0131) were significant in favor of the delayed elective approach.

CONCLUSIONS: Delayed elective sigmoid resection demonstrates benefit in terms of reduced conversion rates and shortened operative time as opposed to an early approach. Conversely, operative morbidities seem to be unaffected by the timing of surgery. However, a final and robust conclusion based on the included observational cohort studies must be cautiously made. We therefore highly advocate larger randomized controlled trials with homogenous study protocols.

Cancer risk in patients with diverticular disease: a nationwide cohort study.

Journal of the National Cancer Institute pii:6749573 [Epub ahead of print].

BACKGROUND: There are little data on diverticular disease and cancer development, other than colorectal cancer.

METHODS: We conducted a population-based, matched cohort study with linkage of nationwide registers to the ESPRESSO histopathology cohort. We included 75,704 patients with a diagnosis of diverticular disease and colorectal histopathology and 313,480 reference individuals from the general population matched on age, sex, calendar year, and county. Cox proportional hazards models estimated multivariable-adjusted hazard ratios (HRs) for associations between diverticular disease and overall cancer and specific cancers.

RESULTS: Over a median follow-up of 6 years, we documented 12,846 incident cancers among patients with diverticular disease and 43,354 incident cancers among reference individuals from the general population. Compared to reference individuals, patients with diverticular disease had significantly increased overall cancer incidence (24.5 vs. 18.1 per 1,000 person-years), equivalent to 1 extra cancer case in 16 individuals with diverticular disease followed for ten years. After adjusting for covariates, having a diagnosis of diverticular disease was associated with a 33% increased risk of overall cancer (95% confidence interval (CI)=1.31-1.36). The risk increases also persisted compared to siblings as secondary comparators (HR = 1.26; 95%CI = 1.21-1.32). Patients with diverticular disease also had increased risk of specific cancers, including colon cancer (HR = 1.71; 95%CI = 1.60-1.82), liver cancer (HR = 1.72; 95%CI = 1.41-2.10), pancreatic cancer (HR = 1.62; 95%CI = 1.42-1.84), and lung cancer (HR = 1.50; 95%CI = 1.39-1.61). The increase in colorectal cancer risk was primarily restricted to the first year of follow-up, and especially early cancer stages.

CONCLUSIONS: Patients with diverticular disease who have colorectal histopathology have an increased risk of overall incident cancer.

Removal of Indwelling Urinary Catheter Two Days After Colovesical Fistula Repair: a Single-Arm Prospective Trial.

Journal of gastrointestinal surgery : official journal of the Society for Surgery of the Alimentary Tract, 26(12):2597-2599.

BACKGROUND: Colovesical fistulas are uncommon but associated with significant morbidity and reduced quality of life. In cases with diverticular etiology, surgical management involves single-stage colonic resection with anastomosis and simple or no bladder repair. No single approach to postoperative bladder management has been widely accepted. Although historically a Foley catheter remained in place for about 2 weeks, elevated risk of the attendant complications has motivated exploring shorter durations. This study examined the feasibility and safety of removing the Foley catheter on postoperative day two.

METHODS: Patients with colovesical fistula due to diverticular disease undergoing colectomy with simple or no bladder repair were enrolled in this single-arm prospective trial conducted at a large community health system. The primary outcome was removal of the Foley catheter on postoperative day two after negative cystogram without re-insertion prior to hospital discharge. Secondary outcomes were complications after Foley catheter removal and hospital length of stay. Ninety-five percent confidence intervals were calculated for the outcomes.

RESULTS: Twenty-four patients were enrolled. About half (54%) of procedures were open, with 33% requiring simple bladder repair. Ninety-six percent (95% confidence interval, 79-99%) of patients had their Foley catheter removed on postoperative day two after a negative cystogram. There were no complications. Mean (range) hospital length of stay was 4.3 (2-6) days.

DISCUSSION: Foley catheter removal after negative cystogram on postoperative day two appears to be feasible and safe in the setting of diverticulitis-related colovesical fistula repair. Further research on a larger number of patients should confirm these findings.

Pyometra and Pyogenic Spondylitis with Suspected Involvement of Diverticulitis of the Sigmoid Colon: A Case Report.

Internal medicine (Tokyo, Japan) [Epub ahead of print].

Pyometra is a rare disease in which pus accumulates in the uterus and is typically caused by stenosis of the cervix. Only a few case reports have indicated that diverticular disease causes pyometra. We herein report an 83-year-old woman presented to our hospital with a fever, loss of appetite, general fatigue and back pain. After some inspections, she was diagnosed with pyometra and lumbar pyogenic spondylitis secondary to diverticulitis of the sigmoid colon. We performed transvaginal drainage and continued antibiotic administration for about three months. The pyometra and pyogenic spondylitis successfully resolved, and she did not experience any recurrence.

Laparoscopic Hartmann's reversal has better clinical outcomes compared to open surgery: An international multicenter cohort study involving 502 patients.

Health science reports, 5(5):e788.

BACKGROUND: Hartmann's procedure (HP) is used in surgical emergencies such as colonic perforation and colonic obstruction. "Temporary" colostomy performed during HP is not always reversed in part due to potential morbidity and mortality associated with reversal. There are several contributing factors for patients requiring a permanent colostomy following HP. Therefore, there is still some discussion about which technique to use. The aim of this study was to evaluate perioperative variables of patients undergoing Hartmann's reversal using a laparoscopic and open approach.

METHODS: The multicenter retrospective cohort study was done between January 2009 and December 2019 at 14 institutions globally. Patients who underwent Hartmann's reversal laparoscopic (LS) and open (OS) approaches were evaluated and compared. Sociodemographic, preoperative, intraoperative variables, and surgical outcomes were analyzed. The main outcomes evaluated were 30-day mortality, length of stay, complications, and postoperative outcomes.

RESULTS: Five hundred and two patients (264 in the LS and 238 in the OS group) were included. The most prevalent sex was male in 53.7%, the most common indication was complicated diverticular disease in 69.9%, and 85% were American Society of Anesthesiologist (ASA) II-III. Intraoperative complications were noted in 5.3% and 3.4% in the LS and OS groups, respectively. Small bowel injuries were the most common intraoperative injury in 8.3%, with a higher incidence in the OS group compared with the LS group (12.2% vs. 4.9%, p < 0.5). Inadvertent injuries were more common in the small bowel (3%) in the LS group. A total of 17.2% in the OS versus 13.3% in the LS group required intensive care unit (ICU) admission (p = 0.2). The most frequent postoperative complication was ileus (12.6% in OS vs. 9.8% in LS group, p = 0.4)). Reintervention was required mainly in the OS group (15.5% vs. 5.3% in LS group, p < 0.5); mortality rate was 1%.

CONCLUSIONS: Laparoscopic Hartmann's reversal is safe and feasible, associated with superior clinical outcomes compared with open surgery.

Adjunctive endoscopic clip marking enhances non-operative management of massive lower gastrointestinal bleeding.

ANZ journal of surgery [Epub ahead of print].

BACKGROUNDS: Massive lower gastrointestinal bleeding (LGB) is common especially in elderly patients. Controversy in the approach to management stems from location of bleeding and morbidity of surgery. Colonic diverticula disease (CD) is the leading cause of painless haematochezia and haemodynamic instability.

METHODS: The use of a novel technique of endoscopic pre-marking (EPM) with radiopaque metal clips to localize is described. EPM guided superselective active transarterial embolization (A-TAE) when active vascular blush was seen. When no active contrast extravasation was seen, EPM also guided prophylactic superselective transarterial embolization (P-TAE).

RESULTS: From May 2004 to December 2021, there were 36 patients with massive LGB from diverticular disease encompassing 44 separate bleeding episodes. Spontaneous haemostasis was observed in 18.2% (8/44). The overall success rate in non-operative management was 83.3% (30/36) patients. Three patients proceeded for emergency surgery. Of the 36 patients, six patients had documented EPM followed by TAE due to recurrent bleed in the same episode. A-TAE was performed in two patients. P-TAE was performed in the four patients without active contrast extravasation. Initial haemostasis was successful in five out of six patients. One patient failed embolization and proceeded to emergency surgery. Three months later, one patient encountered late rebleeding and was scheduled for elective colectomy. None of the six developed intestinal infarction from embolization. The 30-day mortality was 0%.

CONCLUSION: A consistent approach to LGB and defined protocol of endoscopic haemostasis, with routine EPM and embolization, has the potential to mitigate the morbidity and mortality in this group of vulnerable patients.

Single-incision laparoscopic ileocolectomy for solitary cecal colon diverticulitis with calcified fecalith: a case report.

Journal of surgical case reports, 2022(8):rjac323.

The prevalence of colonic diverticular disease has been on the increase in Japan due to an increase in westernized diet and a rapidly aging population. However, solitary cecal diverticulum is rare and considered congenital in etiology. Solitary cecal diverticulitis with calcified fecaliths is even rarer. Herein, we report a case of cecal colon diverticulitis caused by a calcified fecalith in a 38-year-old woman treated with single-incision laparoscopic surgery. To the best of our knowledge, this report describes the first case of cecal colon diverticulitis caused by a calcified fecalith that was successfully treated with single-incision laparoscopic ileocolectomy.

Recurrent diverticulitis after elective surgery.

International journal of colorectal disease, 37(10):2149-2155.

PURPOSE: Elective sigmoid resection is proposed as a treatment for symptomatic diverticular disease for the possible improvement in quality of life achievable. Albeit encouraging results have been reported, recurrent diverticulitis is still a concern deeply affecting quality of life. The aim of this study is to determine the rate of recurrent diverticulitis after elective sigmoid resection and to look for possible perioperative risk factors.

METHODS: Patients who underwent elective resection for DD with at least a 3-year follow-up were included. Postoperative recurrence was defined as left-sided or lower abdominal pain, with CT scan-confirmed findings of diverticulitis.

RESULTS: Twenty of 232 (8.6%) patients developed CT-proven recurrent diverticulitis after elective surgery. All the 20 recurrent diverticulitis were uncomplicated and did not need surgery. Eighty-five percent of the recurrences occurred in patients with a preoperative diagnosis of uncomplicated DD, 70% in patients who had at least 4 episodes of diverticulitis, and 70% in patients with a history of diverticulitis extended to the descending colon. Univariate analysis showed that recurrence was associated with diverticulitis of the sigmoid and of the descending colon (p = 0.04), with a preoperative diagnosis of IBS (p = 0.04) and with a longer than 5 years diverticular disease (p = 0.03). Multivariate analysis was not able to determine risks factors for recurrence.

CONCLUSION: Our study showed that patients with a preoperative diagnosis of IBS, diverticulitis involving the descending colon, and a long-lasting disease are more likely to have recurrent diverticulitis. However, these variables could not be assumed as risk factors.

Trends in the Management of Non-emergent Surgery for Diverticular Disease and the Impact of Practice Parameters.

The American surgeon [Epub ahead of print].

BACKGROUND: Due to the rise in diverticular disease, the ASCRS developed practice parameters to ensure high-quality patient care. Our study aims to evaluate the impact of the 2014 practice parameters on the treatment of non-emergent left-sided diverticular disease.

METHODS: This is a retrospective cohort study using the ACS-National Surgical Quality Improvement Project (ACS-NSQIP). Elective sigmoid resections performed by year were evaluated and compared before and after practice parameters were published.

RESULTS: Overall, 46,950 patients met inclusion criteria. There was a significant decrease in the number of non-emergent operations when evaluating before and after guideline implementation (P < .001). There was a significant decrease in the number of patients younger than 50 years of age operated electively for diverticular disease (25.8% vs. 23.9%, P = .005). Adoption of minimally invasive surgery continued to increase significantly throughout the study period.

CONCLUSIONS: Publication of the 2014 ASCRS practice parameters is associated with a change in management of diverticular disease in the non-emergent setting.

The relationship between Parkinson's disease and gastrointestinal diseases.

Frontiers in aging neuroscience, 14:955919.

An increasing number of studies have provided evidence for the hypothesis that the pathogenesis of Parkinson's disease (PD) may derive from the gut. Firstly, Lewy pathology can be induced in the enteric nervous system (ENS) and be transported to the central nervous system (CNS) via the vagal nerve. Secondly, the altered composition of gut microbiota causes an imbalance between beneficial and deleterious microbial metabolites which interacts with the increased gut permeability and the gut inflammation as well as the systemic inflammation. The activated inflammatory status then affects the CNS and promotes the pathology of PD. Given the above-mentioned findings, researchers start to pay attention to the connection between PD and gastrointestinal diseases including irritable bowel syndrome, inflammatory bowel disease (IBD), microscopic colitis (MC), gastrointestinal infections, gastrointestinal neoplasms, and colonic diverticular disease (CDD). This review focuses on the association between PD and gastrointestinal diseases as well as the pathogenesis of PD from the gut.

Defining diverticular fistula through inpatient admissions: a population study.

Surgical endoscopy [Epub ahead of print].

BACKGROUND: Diverticular fistula, a pathologic connection from the colon to the skin or another organ, is an uncommon sequela of diverticular disease. It is generally considered an indication for surgery. The current literature is limited in terms of defining the epidemiology of this disease process. This analysis defines the demographics of fistulous diverticular disease on a national level.

METHODS: A retrospective review of the 2018 National Inpatient Sample (NIS) was conducted, using ICD-10 codes for diverticular disease, diverticular-associated fistulas, and associated surgeries. Demographic factors were compared between groups, and several sub-group analyses were performed.

RESULTS: A total of 7,105,498 discharges were recorded: 119,115 (1.68%) with non-fistulizing diverticular disease and 3,843 (0.05%) with diverticular fistula. Patients with diverticular fistula were more likely to be younger (64.7 v 68.2 years, p < .0001) and female (57.3% v 55.4%, p = 0.028) than patients with non-fistulizing disease. They were also more likely to undergo surgery (64.9% v 25.7%, p < .0001), to be admitted electively (44.7% v 12.0%, p < .0001), and to have a longer length of stay (LOS) (mean 8.07 v 5.20 days, p < .0001). Diverticular fistula patients that underwent surgery were more likely to be male (44.8% v 39.0%, p = 0.003), to be admitted electively (65.3% v 6.7%, p < .0001), and to have longer LOS (mean 8.74 v 6.81 days, p < .0001) than those who received medical treatment alone.

CONCLUSION: Diverticular fistula is a rare diagnosis, accounting for 0.05% of total admissions and 3.12% of admissions for diverticular disease. However, this is more common than the previously reported rate of < 0.1% of diverticular disease admissions. While surgery is generally indicated for diverticular fistula, only 64.9% of patients underwent surgical treatment. Although this study is limited by its retrospective nature and use of administrative data, our findings elucidate the prevalence and patterns of inpatient admissions for diverticular fistula in the United States.

Risk Factors for the Failure of Non-operative Management Among Patients Admitted for Colonic Diverticulitis.

The American surgeon [Epub ahead of print].

BACKGROUND: Diverticulitis is one of the most diagnosed gastrointestinal diseases in the country, and its incidence has risen over time, especially among younger populations, with increasing attempts at non-operative management. We elected to look at acute diverticular disease from the lens of a failure analysis, where we could estimate the hazard of requiring operative intervention based upon several clinical factors.

MATERIALS AND METHODS: The National Inpatient Sample (NIS) was queried between 2010 and 2015 for unplanned admissions among adults with a primary diagnosis of diverticulitis. We used a proportional hazards regression to estimate the hazard of failed non-operative management from multiple clinical covariates, measured as the number of inpatient days from admission until colonic resection. We also evaluated patients who received percutaneous drainage, to investigate whether this was associated with decreasing the failure rate of non-operative management.

RESULTS: A total of 830,993 discharges over the study period, of whom 83,628 (10.1%) underwent operative resection during the hospitalization, and 35,796 (4.3%) patients underwent percutaneous drainage. Half of all operations occurred by hospital day 1. Among patients treated with percutaneous drainage, 11% went on to require operative intervention. The presence of a peritoneal abscess (HR 3.20, P < .01) and sepsis (HR 4.16, P < .01) were the strongest predictors of failing non-operative management. Among the subset of patients with percutaneous drains, the mean time from admission to drain placement was 2.3 days.

CONCLUSION: Overall 10.1% of unplanned admissions for diverticulitis result in inpatient operative resection, most of which occurred on the day of admission. Percutaneous drainage was associated with an 11% operative rate.

Diverticular Disease: Rapid Evidence Review.

American family physician, 106(2):150-156.

Diverticulitis should be suspected in patients with isolated left lower quadrant pain, abdominal distention or rigidity, fever, and leukocytosis. Initial laboratory workup includes a complete blood count, basic metabolic panel, urinalysis, and C-reactive protein measurement. Computed tomography with intravenous contrast is the preferred imaging modality, if needed to confirm diagnosis and assess for complications of diverticulitis. Treatment decisions are based on the categorization of disease as complicated vs. uncomplicated. Selected patients with uncomplicated diverticulitis may be treated without antibiotics. Complicated diverticulitis is treated in the hospital with modified diet or bowel rest, antibiotics, and pain control. Abscesses that are 3 cm or larger should be treated with percutaneous drainage. Emergent surgery is reserved for when percutaneous drainage fails or the patient's clinical condition worsens despite adequate therapy. Colonoscopy should not be performed during the flare-up, but should be considered six weeks after resolution of symptoms in patients with complicated diverticulitis who have not had a high-quality colonoscopy in the past year. Diverticulitis prevention measures include consuming a vegetarian diet or high-quality diet (high in fruits, vegetables, whole grains, and legumes), limiting red meat and sweets, achieving or maintaining a body mass index of 18 to 25 kg per m2, being physically active, and avoiding tobacco and long-term nonsteroidal anti-inflammatory drugs. Partial colectomy is not routinely recommended for diverticulitis prevention and should be reserved for patients with more than three recurrences or abscess formation requiring percutaneous drainage.

Diverticular disease in a pediatric patient with Crohn's disease mimicking a perforated post-appendectomy appendiceal stump.

Journal of surgical case reports, 2022(8):rjac355.

We present the finding of a diverticulum in the colonic wall of the cecum, arising in the context of ileocecal stricture in a child with Crohn disease mimicking a post-appendectomy perforated appendiceal stump. To our knowledge, a non-Meckel diverticulum in a pediatric patient with Crohn disease has not yet been reported and we examine the mechanics behind it. According to the Laplace Law, the pressure inside a container with curved walls is inversely proportional to its radius. A diverticulum forms at the point of maximum stricture and at the locus of least resistance (weakness) in the bowel wall due to the inflammatory bowel disease. The long-time interval between diagnosis of ileocecal stricture and surgery (9 months) is important to allow the formation of this diverticulum. Continued follow-up in adulthood is warranted due to an increased risk of intestinal diverticular disease and neoplasms in patients with Crohn disease.

Plant-based diets and long-term health: findings from the EPIC-Oxford study.

The Proceedings of the Nutrition Society, 81(2):190-198.

The concept of plant-based diets has become popular due to the purported benefits for both human health and environmental impact. Although 'plant-based' is sometimes used to indicate omnivorous diets with a relatively small component of animal foods, here we take it to mean either vegetarian (plant-based plus dairy products and/or eggs) or vegan (100% plant-based). Important characteristics of plant-based diets which would be expected to be beneficial for long-term health are low intakes of saturated fat and high intakes of dietary fibre, whereas potentially deleterious characteristics are the risk of low intakes of some micronutrients such as vitamin B12, vitamin D, calcium and iodine, particularly in vegans. Vegetarians and vegans typically have lower BMI, serum LDL cholesterol and blood pressure than comparable regular meat-eaters, as well as lower bone mineral density. Vegetarians in the EPIC-Oxford study have a relatively low risk of IHD, diabetes, diverticular disease, kidney stones, cataracts and possibly some cancers, but a relatively high risk of stroke (principally haemorrhagic stroke) and bone fractures, in comparison with meat-eaters. Vegans in EPIC-Oxford have a lower risk of diabetes, diverticular disease and cataracts and a higher risk of fractures, but there are insufficient data for other conditions to draw conclusions. Overall, the health of people following plant-based diets appears to be generally good, with advantages but also some risks, and the extent to which the risks may be mitigated by optimal food choices, fortification and supplementation is not yet known.

Single-Center Results of Colorectal Procedures Performed with Fully Articulated Laparoscopic Artisential® Devices.

Surgical technology international, 41: pii:sti41/1605 [Epub ahead of print].

INTRODUCTION: The ArtiSential® line of products from LivsMed (Seongnam, Republic of Korea) are fully articulated hand-held laparoscopic instruments, possessing end-effectors that closely imitate those of surgical robots with regard to shape and dexterity. Feasibility and safety studies describing the initial experiences with these devices in upper and lower gastrointestinal as well as thoracic surgery have been published. This report presents the outcomes of the largest cohort to date of colorectal procedures performed with Artisential® instruments in a single center.

MATERIALS AND METHODS: Between September 2020 and May 2022, prospective data were collected from patients undergoing ArtiSential®-assisted laparoscopic surgery. A retrospective data analysis was performed for all patients who underwent ArtiSential®-assisted surgery for colorectal indication. Indications for colorectal surgery included rectal and colon cancer, complicated diverticular disease, inflammatory bowel disease, obstructed defecation syndrome, endoscopically nonresectable adenomas and chronic anastomotic fistula following a low anterior resection (LAR).

RESULTS: A total of 73 patients (49 males, 24 females) underwent Artisential®-assisted colorectal surgery. The median age of the patients was 62 years (range 34-88) and the median body mass index (BMI) was 27 kg/m2 (range 19-51). Indications for surgery were colorectal malignancy (n=55, 75%), complicated diverticular disease (n=11, 15%), obstructed defecation syndrome (n=3, 4.1%), inflammatory bowel disease (n=2, 2.7%), endoscopically nonresectable adenomas (n=1, 1.4%) and chronic anastomotic fistula following LAR (n=1, 1.4%). The median operative time was 240 minutes (range 95-458). There were no conversions to standard straight-stick laparoscopy or to laparotomy, and no intraoperative complications. All patients who were operated upon for colorectal malignancy had an adequate oncological resection (R0=100%). The median length of stay was 7 days (range 3-36). The overall complication rate was 10.9 % (Clavien-Dindo II: 1 patient, Clavien-Dindo IIIb: 7 patients). There were two readmissions, one unrelated, and no mortalities.

CONCLUSIONS: This larger series confirms the results of previous reports on the safety and feasibility of Artisential® use in complex laparoscopic colorectal surgery. To examine potential benefits in outcome, comparative studies involving Artisential®, robotic-assisted and standard laparoscopic surgery are needed.

Impact of the first wave of COVID-19 on outcomes following emergency admissions for common acute surgical conditions: analysis of a national database in England.

The British journal of surgery, 109(10):984-994.

BACKGROUND: This study assessed the impact of the first COVID-19 wave in England on outcomes for acute appendicitis, gallstone disease, intestinal obstruction, diverticular disease, and abdominal wall hernia.

METHODS: Emergency surgical admissions for patients aged 18 years and older to 124 NHS Trust hospitals between January and June in 2019 and 2020 were extracted from Hospital Episode Statistics. The risk of 90-day mortality after admission during weeks 11-19 in 2020 (national lockdown) and 2019 (pre-COVID-19) was estimated using multilevel logistic regression with case-mix adjustment. The primary outcome was all-cause mortality at 90 days.

RESULTS: There were 12 231 emergency admissions and 564 deaths within 90 days during weeks 11-19 in 2020, compared with 18 428 admissions and 542 deaths in the same interval in 2019. Overall, 90-day mortality was higher in 2020 versus 2019, with an adjusted OR of 1.95 (95 per cent c.i. 0.78 to 4.89) for appendicitis, 2.66 (1.81 to 3.92) for gallstone disease, 1.99 (1.44 to 2.74) for diverticular disease, 1.70 (1.13 to 2.55) for hernia, and 1.22 (1.01 to 1.47) for intestinal obstruction. After emergency surgery, 90-day mortality was higher in 2020 versus 2019 for gallstone disease (OR 3.37, 1.26 to 9.02), diverticular disease (OR 2.35, 1.16 to 4.73), and hernia (OR 2.34, 1.23 to 4.45). For intestinal obstruction, the corresponding OR was 0.91 (0.59 to 1.41). For admissions not leading to emergency surgery, mortality was higher in 2020 versus 2019 for gallstone disease (OR 2.55, 1.67 to 3.88), diverticular disease (1.90, 1.32 to 2.73), and intestinal obstruction (OR 1.30, 1.06 to 1.60).

CONCLUSION: Emergency admission was reduced during the first lockdown in England and this was associated with higher 90-day mortality.

Polygenic Risk Prediction in Diverticulitis.

Annals of surgery pii:00000658-990000000-00180 [Epub ahead of print].

OBJECTIVE: To derive and validate a polygenic risk score (PRS) to predict the occurrence and severity of diverticulitis and to understand the potential for incorporation of a PRS in current decision-making.

SUMMARY BACKGROUND DATA: PRS quantifies genetic variation into a continuous measure of risk. There is a need for improved risk stratification to guide surgical decision-making that could be fulfilled by PRS. It is unknown how surgeons might integrate PRS in decision-making.

METHODS: We derived a PRS with 44 SNPs associated with diverticular disease in the United Kingdom Biobank and validated this score in the Michigan Genomics Initiative (MGI). We performed a discrete choice experiment of practicing colorectal surgeons. Surgeons rated the influence of clinical factors and a hypothetical polygenic risk prediction tool.

RESULTS: Among 2,812 MGI participants with diverticular disease, 1,964 were asymptomatic, 574 had mild disease, and 274 had severe disease. PRS was associated with occurrence and severity. Patients in the highest PRS decile were more likely to have diverticulitis (OR=1.84 (95%CI 1.42-2.38)) and more likely to have severe diverticulitis (OR=1.61 (95% CI 1.04-2.51)) than the bottom 50%. Among 213 surveyed surgeons, extreme disease-specific factors had the largest utility (3 episodes in the last year, +74.4; percutaneous drain, + 69.4). Factors with strongest influence against surgery included 1 lifetime episode (-63.3), outpatient management (-54.9), and patient preference (-39.6) PRS was predicted to have high utility, (+71).

CONCLUSIONS: A PRS derived from a large national biobank was externally validated, and found to be associated with the incidence and severity of diverticulitis. Surgeons have clear guidance at clinical extremes, but demonstrate equipoise in intermediate scenarios. Surgeons are receptive to PRS, which may be most useful in marginal clinical situations. Given the current lack of accurate prognostication in recurrent diverticulitis, PRS may provide a novel approach for improving patient counseling and decision-making.

Value of computed tomography scores in complicated acute diverticulitis.

ANZ journal of surgery, 92(11):2935-2941.

BACKGROUND: Diverticular disease remains one of the most common conditions in the western world. Up to 25% of patients with diverticular disease require hospitalization, 15-30% of those of which require surgical intervention. CT scoring systems have been proposed as means to drive assessment and stratify patients necessitating hospital intervention. To assess and correlate CT scoring systems with clinical and surgical outcomes.

METHODS: Retrospective cohort analysis at a single institution. Single institutional assessment with patients presenting to emergency with a CT diagnosed episode of acute diverticulitis. One hundred and eighty-nine patients were included in the study, 61% of which were male. Patient demographics, comorbidities, medications, biochemistry and inflammatory markers, type of complication following acute diverticulitis, operative/procedural intervention, hospital outcome and mortality were measured. CT scoring systems assessed included modified Hinchey, modified Neff, World Society of Emergency Surgery (WSES) and modified Siewert scoring systems.

RESULTS: Majority of patients had left-sided diverticulitis (91%) with localized air (88%) and pericolic abscess (49%) the most common radiological findings. 28% of patients required radiological and/or surgical management with 12% requiring intensive care unit (ICU) admission. There was a general trend for surgical/radiological intervention as the scores increased in severity. The four scoring systems were found to be statistically significant predictors of any intervention and of ICU admission with minimal statistical differences across the different scoring systems.

CONCLUSION: Radiological CT scores for complicated diverticulitis are at best, moderate predictors of clinical and surgical outcomes and may serve to guide management with minimal statistical differences across different scores.

Enterolith Causing Small Bowel Obstruction: Report of a Case and Review of Literature.

Clinical and experimental gastroenterology, 15:101-104.

Enterolithiasis, also known as gastro-intestinal concretions, is an uncommon medical disorder that arises from intestinal stasis. Enteroliths are commonly caused by tuberculosis-related constriction and arise from intestinal diverticula. Small bowel obstruction caused by an enterolith is extremely uncommon and might be difficult to diagnose. The mortality rate of uncomplicated enterolithiasis is relatively low, but it rises to 3% in patients who have background comorbid illness, have significant bowel obstruction, and are diagnosed late. We present a rare case of an uncomplicated partial intestinal obstruction caused by an enterolith in an elderly male patient with small bowel diverticular disease who was treated nonoperatively and did not develop further symptoms in the six-month follow-up and discuss the difficulty in diagnosis and its management.

Intraoperative bowel perfusion quantification with hyperspectral imaging: a guidance tool for precision colorectal surgery.

Surgical endoscopy, 36(11):8520-8532.

BACKGROUND: Poor anastomotic perfusion can cause anastomotic leaks (AL). Hyperspectral imaging (HSI), previously validated experimentally, provides accurate, real-time, contrast-free intestinal perfusion quantification. Clinical experience with HSI is limited. In this study, HSI was used to evaluate bowel perfusion intraoperatively.

METHODS: Fifty-two patients undergoing elective colorectal surgeries for neoplasia (n = 40) or diverticular disease (n = 12), were enrolled. Intestinal perfusion was assessed with HSI (TIVITA®, Diaspective Vision, Am Salzhaff, Germany). This device generates a perfusion heat map reflecting the tissue oxygen saturation (StO2) amount. Prior to anastomose creation, the clinical transection line (CTL) was highlighted on the proximal bowel and imaged with HSI. Upon StO2 heat map evaluation, the hyperspectral transection line (HTL) was identified. In case of CTL/HTL discrepancy > 5 mm, the bowel was always resected at the HTL. HSI outcomes were compared to the clinical ones.

RESULTS: AL occurred in one patient who underwent neoadjuvant radiochemotherapy and ultralow anterior resection for rectal cancer. HSI assessment was feasible in all patients, and StO2-values were significantly higher at proximal segments than distal ones. Twenty-six patients showed CTL/HTL discrepancy, and these patients had a lower mean StO2 (54.55 ± 21.30%) than patients without discrepancy (65.10 ± 21.30%, p = 0.000). Patients undergoing neoadjuvant radiochemotherapy showed a lower StO2 (51.41 ± 23.41%) than non-neoadjuvated patients (60.51 ± 24.98%, p = 0.010).

CONCLUSION: HSI is useful in detecting intraoperatively marginally perfused segments, for which the clinical appreciation is unreliable. Intestinal vascular supply is lower in patients undergoing neoadjuvant radiochemotherapy, and this novel finding together with the clinical impact of HSI perfusion quantification deserves further investigation in larger trials.

Colonic Diverticulosis Is Not Associated With Painful Abdominal Symptoms in a US Population.

Gastro hep advances, 1(4):659-665.

BACKGROUND AND AIMS: Symptomatic uncomplicated diverticular disease is a controversial diagnosis defined as chronic gastrointestinal symptoms in patients with diverticulosis. We assessed whether individuals with diverticulosis had an increased risk of abdominal pain, irritable bowel syndrome, or altered bowel habits.

METHODS: We performed a prospective cohort study of participants who had a first-time screening colonoscopy at the University of North Carolina between 2013 and 2015. The colonoscopy included a detailed assessment for diverticulosis. Participants completed a follow-up interview between 2019 and 2020 to measure bowel habits and gastrointestinal symptoms. Poisson regression was used to estimate relative risk and 95% confidence intervals (CIs).

RESULTS: Among the 310 participants, 128 (41%) had diverticulosis at baseline. Follow-up interviews were performed a mean of 6.8 years after the baseline colonoscopy. After adjustment for confounders, there was no association between diverticulosis and abdominal pain lasting >24 hours (relative risk [RR], 0.40; 95% CI, 0.05-3.45) or symptoms of irritable bowel syndrome (RR, 1.30; 95% CI, 0.69-2.42) at the time of follow-up. Compared to those with no diverticulosis, participants with diverticulosis were more likely to have more frequent bowel movements per day (RR, 1.60; 95% CI, 1.05-2.44). The association was stronger in participants with >10 diverticula (RR, 2.03; 95% CI, 1.19-3.48). Diverticulosis was not associated with altered stool consistency.

CONCLUSION: These findings suggest that diverticulosis is associated with more frequent bowel movements contrary to the widespread belief that patients with diverticulosis are constipated. Diverticulosis was not associated with abdominal pain or symptoms of irritable bowel syndrome. The diagnosis of symptomatic uncomplicated diverticular disease must be reconsidered.

Distant free air is not a contraindication for definitive laparoscopic treatment of acute perforated diverticulitis: a multi-center experience.

Updates in surgery, 74(5):1665-1673.

The paradigm of emergency laparotomy with sigmoid resection and protective stoma has been challenged for perforated diverticular disease (PDD) with free extraluminal air. Early clinical stabilization could lead to interval laparoscopic resection without stoma within 2 weeks from perforation. Patients admitted for acute diverticulitis underwent abdominal computed tomography (CT) scan. When free air was seen, endoluminal enema was administred. All patients underwent assessement of clinical stability. In unstable patients, upfront emergency surgery was performed. Stable patients underwent a conservative management consisting in fasting, central line intravenous fluids, antibiotic therapy, pain management, O2 therapy and percutaneous radiological drainage when indicated. In successful conservative management early interval surgery was planned within 15 days. Early delayed definitive laparoscopic treatment (EDDLT) was defined as laparoscopic resection of the affected colon without ostomy. A total of 235 patients were admitted to the emergency department for PDD. Among these, 142 had pericolic free air and were excluded from the study. Ninety-three had distant free air. Thirty-seven were hemodynamically unstable and underwent upfront surgery. Fifty-six patients showed a clinical stability and started on EDDLT. EDDLT was successfully performed in 36 patients (64.3%). In 20 patients (35.7%) EDDLT was unsuccessful. At multivariate analysis, distant CT extravasation of endoluminal contrast was independently associated with unsuccessful EDDLT (OR 2.1, CI 0.94-5.32). Patients with distant extraluminal free air after PDD may be treated with early delayed surgery after intensive medical therapy. Distant spread of endoluminal contrast at CT was a risk factor for unsuccessful EDDLT often indicating fecal peritonitis.

Gut Microbiota Association with Diverticular Disease Pathogenesis and Progression: A Systematic Review.

Digestive diseases and sciences [Epub ahead of print].

INTRODUCTION: Growing evidence supports the role of the intestinal microbiome in the development of different intestinal and extraintestinal diseases. Diverticular disease (DD) is one of the most common disorders in western countries. In the last years, different articles have suggested a possible role of the intestinal microbiome in DD pathogenesis and in the development of acute diverticulitis (AD). This systematic review aimed to clarify the current knowledge on the role of the intestinal microbiome in colonic diverticulitis in different stages according to the 2009 PRISMA guidelines.

MATERIALS AND METHODS: Two independent reviewers searched the literature in a systematic manner through online databases, including Medline, Scopus, Embase, Cochrane Oral Health Group Specialized Register, ProQuest Dissertations and Theses Database, and Google Scholar. Patients with any stage of disease were included. The Newcastle-Ottawa scale for case-control and cohort studies was used for the quality assessment of the selected articles.

RESULTS: Overall, nine studies were included in the review. Only one article was focused on patients with AD, while all other articles only considered patients with DD without acute inflammation signs. Enterobacteriaceae seems to be the microbiota most associated with the disease, followed by Bifidobacteria.

CONCLUSIONS: All the included studies showed great heterogeneity in population characteristics and sampling methods. Therefore, given the high prevalence of colonic diverticulitis in the general population, further studies are needed to clarify the role of the intestinal microbiome, paving the way to new target therapies with important social implications.

Concomitant brain and liver abscesses: a rare complication of acute diverticulitis.

Journal of surgical case reports, 2022(6):rjac297.

Diverticular disease is one of the most common colonic pathologies in the Western world. In the UK, ~80% of the population aged over 85 years are diagnosed with it. Most of these cases are asymptomatic. Yet, they can become problematic when the diverticula bleed, become infected (diverticulitis) or perforate. Other well-known complications of diverticular disease are acute inflammation, stenosis, fistulation and abscess formation. In this case report, we describe a delayed presentation of metastatic abscesses (liver and brain) from a prior acute diverticulitis with contained perforation and abscess formation.

Diagnoses after newly recorded abdominal pain in primary care: observational cohort study.

The British journal of general practice : the journal of the Royal College of General Practitioners, 72(721):e564-e570.

BACKGROUND: Non-acute abdominal pain in primary care is diagnostically challenging.

AIM: To quantify the 1-year cumulative incidence of 35 non-malignant diagnoses and nine cancers in adults after newly recorded abdominal pain in primary care.

DESIGN AND SETTING: Observational cohort study of 125 793 Clinical Practice Research Datalink GOLD records.

METHOD: Participants, aged ≥40 years, had newly recorded abdominal pain between 1 January 2009 and 31 December 2013. Age- and sex-stratified 1-year cumulative incidence by diagnosis is reported.

RESULTS: Most (>70%) participants had no pre-specified diagnoses after newly recorded abdominal pain. Non-malignant diagnoses were most common: upper gastrointestinal problems (gastro-oesophageal reflux disease, hiatus hernia, gastritis, oesophagitis, and gastric/duodenal ulcer) in males and urinary tract infection in females. The incidence of upper gastrointestinal problems plateaued at age ≥60 years (aged 40-59 years: males 4.9%, 95% confidence interval [CI] = 4.6 to 5.1, females 4.0%, 95% CI = 3.8 to 4.2; aged 60-69 years: males 5.8%, 95% CI = 5.4 to 6.2, females 5.4%, 95% CI = 5.1 to 5.8). Urinary tract infection incidence increased with age (aged 40-59 years: females 5.1%, 95% CI = 4.8 to 5.3, males 1.1%, 95% CI = 1.0 to 1.2; aged ≥70 years: females 8.0%, 95% CI = 7.6 to 8.4, males 3.3%, 95% CI = 3.0 to 3.6%). Diverticular disease incidence rose with age, plateauing at 4.2% (95% CI = 3.9 to 4.6) in males aged ≥60 years, increasing to 6.1% (95% CI = 5.8 to 6.4) in females aged ≥70 years. Irritable bowel syndrome incidence was higher in females (aged 40-59 years: 2.9%, 95% CI = 2.7 to 3.1) than males (aged 40-59 years: 2.1%, 95% CI = 1.9 to 2.3), decreasing with age to 1.3% (95% CI = 1.2 to 1.5) in females and 0.6% (95% CI = 0.5 to 0.8) in males aged ≥70 years.

CONCLUSION: Although abdominal pain commonly remains unexplained, non-malignant diagnosis are more likely than cancer.

[Adrenal myelolipoma, review of the literature in Mexico apropos of two cases].

Revista medica del Instituto Mexicano del Seguro Social, 60(2):229-235.

BACKGROUND: Adrenal myelolipomas (ML) are rare benign neoplasms compound of adipose and myeloid tissue. Clinically they are usually asymptomatic, being diagnosed generally by incident. In Mexico, there are only 32 published cases of ML, these occur between 37 and 65 years, with the male-female ratio being 1:1.1, clinically they present with abdominal or lumbar pain, open surgery being the main surgical approach (89%).

CLINICAL CASE: We made a literature review of ML in Mexico and present two clinical cases: a 67-year-old man in followup for diverticular disease and a 40-year-old woman with pain in the left upper quadrant. In both cases, tumor resection was performed measuring 9.5 cm and 13.3 cm long respectively.

CONCLUSIONS: We present two new cases in our country that correspond to incidentalomas. In both cases, surgery was performed to confirm the diagnosis, as well as to prevent possible complications.

[Diagnosis and Treatment of Colonic Diverticular Disease].

The Korean journal of gastroenterology = Taehan Sohwagi Hakhoe chi, 79(6):233-243.

Colonic diverticulosis is one of the most common conditions of the digestive system and patients generally remain asymptomatic. However, about 20% of patients develop symptomatic diverticular disease such as acute diverticulitis or diverticular hemorrhage, and these have become a huge burden on healthcare systems worldwide. Recent understanding of the pathophysiology of diverticulosis and diverticular disease suggests the role of multiple factors including genetic and environment. Based on this understanding, a preventive strategy to reduce the risk factors of diverticulosis and diverticular disease is highly recommended. The diagnosis of the acute diverticulitis relies on imaging modalities such as an abdominal-pelvic CT scan together with symptoms and signs. Treatment of diverticular disease should be individualized and include modification of lifestyle, use of antibiotics, and surgery. Recent guidelines recommend pursuing less aggressive treatment for patients with acute diverticulitis. This review will provide an overview of both the existing and evolving understanding regarding colonic diverticulosis and diverticular disease and can help clinicians in the management of their patients with diverticular disease.

Pathophysiology of Diverticular Disease: From Diverticula Formation to Symptom Generation.

International journal of molecular sciences, 23(12):.

Diverticular disease is a common clinical problem, particularly in industrialized countries. In most cases, colonic diverticula remain asymptomatic throughout life and sometimes are found incidentally during colonic imaging in colorectal cancer screening programs in otherwise healthy subjects. Nonetheless, roughly 25% of patients bearing colonic diverticula develop clinical manifestations. Abdominal symptoms associated with diverticula in the absence of inflammation or complications are termed symptomatic uncomplicated diverticular disease (SUDD). The pathophysiology of diverticular disease as well as the mechanisms involved in the shift from an asymptomatic condition to a symptomatic one is still poorly understood. It is accepted that both genetic factors and environment, as well as intestinal microenvironment alterations, have a role in diverticula development and in the different phenotypic expressions of diverticular disease. In the present review, we will summarize the up-to-date knowledge on the pathophysiology of diverticula and their different clinical setting, including diverticulosis and SUDD.

A systematic review and meta-analysis of robotic resections for diverticular disease.

Colorectal disease : the official journal of the Association of Coloproctology of Great Britain and Ireland, 24(10):1105-1116.

AIM: Resection of diverticular disease can be technically challenging. Tissue planes can be difficult to identify intraoperatively due to inflammation or fibrosis. Robotic surgery may improve identification of tissue planes and dissection which can facilitate difficult minimally invasive resections. This systematic review and meta-analysis evaluates the role of robotic surgery compared to laparoscopic surgery in diverticular resection.

METHODS: A systematic review and meta-analysis was performed in accordance with the PRISMA statement. The search was completed using PubMed, OVID MEDLINE and EMBASE. A total of 490 articles were retrieved, and studies reporting primary outcomes for robotic diverticular resection were included in the final analysis. A meta-analysis of studies comparing robotic and laparoscopic surgery was performed on rate of conversion to open surgery and complications.

RESULTS: Fifteen articles (8 cohort studies and 7 case series) reporting 3711 robotic diverticular resections were analysed. In comparison to laparoscopic, robotic surgery for diverticular disease was associated with a reduced conversion to open and a longer operating time. Meta-analysis showed robotic resection was associated with a lower conversion rate compared to laparoscopic surgery (OR: 0.57; 95% CI: 0.49-0.66, p < 0.001). There was no significant difference in grade III and above complications (OR: 0.74; 95% CI: 0.49-1.13, p = 0.17). Operating time was longer with a robotic approach (Hedge's G: 0.43; 95% CI: 0.04-0.81, p = 0.03).

CONCLUSION: Robotic resection is a feasible and safe option in diverticular disease. Although associated with a longer operating time, robotic surgery may render diverticular disease resectable with a minimally invasive approach that would have otherwise necessitated a laparotomy. Randomised controlled data is required to better define the role of robotic surgery for diverticular disease resections.

Total collagen content and distribution is increased in human colon during advancing age.

PloS one, 17(6):e0269689.

BACKGROUND: The effect of ageing on total collagen content of human colon has been poorly investigated. The aim of this study was to determine if ageing altered total collagen content and distribution in the human colon.

METHODS: Macroscopically normal ascending colon was obtained at surgery from cancer patients (n = 31) without diagnosis of diverticular disease or inflammatory bowel disease. Masson's trichrome and Picrosirius red stains were employed to identify the total collagen content and distribution within the sublayers of the colonic wall for adult (22-60 years; 6 males, 6 females) and elderly (70 - 91years; 6 males, 4 female) patients. A hydroxyproline assay evaluated the total collagen concentration for adult (30-64 years; 9 male, 6 female) and elderly (66-91 years; 8 male, 8 female) patients.

KEY RESULTS: Histological studies showed that the percentage mean intensity of total collagen staining in the mucosa, submucosa and muscularis externa was, respectively, 14(1.9) %, 74(3.2) % and 12(1.5) % in the adult ascending colon. Compared with the adults, the total collagen fibres content was increased in the submucosa (mean intensity; 163.1 ± 11.1 vs. 124.5 ± 7.8; P < 0.05) and muscularis externa (42.5 ± 8.0 vs. 20.6 ± 2.8; P < 0.01) of the elderly patients. There was no change in collagen content of the mucosa. The total collagen concentration was increased in the elderly by 16%. Sex-related differences were not found, and data were combined for analysis.

CONCLUSIONS: Greater total collagen content was found in the submucosa and muscularis externa of the elderly human male and female colon. These changes may contribute to a possible loss of function with ageing.

Cardiovascular Risk Factors and Physical Fitness Among Subjects with Asymptomatic Colonic Diverticulosis.

Digestive diseases and sciences [Epub ahead of print].

BACKGROUND: The association between diverticular disease and atherosclerotic cardiovascular disease (ASCVD) has been demonstrated previously, mainly in symptomatic subjects.

AIMS: To evaluate 10 years cardiovascular risk, exercise performance and association to ASCVD among subjects with asymptomatic diverticulosis.

METHODS: A retrospective cross-sectional cohort of self-referred participants in a medical screening program, who underwent a screening colonoscopy. Demographics, clinical and laboratory variables, ASCVD score, and metabolic equivalents (METs) during treadmill stress test were compared between subjects with and without diverticulosis as diagnosed on screening colonoscopy.

RESULTS: 4586 participants underwent screening colonoscopy; 799 (17.4%) had diverticulosis. Among 50-69 yo participants, diverticulosis subjects had a higher ASCVD score compared to non-diverticulosis subjects. Exercise performance was comparable between the groups, across all age groups. Using logistic regression analysis, advanced age group (50-59 yo Adjusted odds ratio (AOR) [95% confidence interval (CI)] 2.57 (1.52-4.34), p < 0.001; 60-69 yo, AOR 2.87 (2.09-3.95), p < 0.001; ≥ 70 yo AOR 4.81 (3.23-7.15), p < 0.001; compared to < 50 yo age group), smoking [AOR 1.27 (1.05-1.55), p = 0.016], HTN [AOR 1.27 (1.03-1.56), p = 0.022], obesity [AOR 1.36 (1.06-1.74), p = 0.014] and male sex [AOR 1.29 (1.02-1.64), p = 0.036] were associated with diverticular detection during screening colonoscopy. Among males, achieving METs score ≥ 10 was inversely associated with diverticular detection during screening colonoscopy [AOR 0.64 (0.43-0.95), p = 0.027].

CONCLUSIONS: Ten years probability for ASCVD estimated by the ASCVD score is higher among subjects with asymptomatic diverticulosis compared to subjects without diverticulosis. Improved exercise performance is demonstrated for the first time to correlate with decreased probability for diverticular disease in screening colonoscopy.

Clostridium tertium Bacteremia: A Marker of an Underlying Perforated Colonic Diverticular Disease in a Non-Neutropenic Patient With COVID-19.

Journal of medical cases, 13(5):212-218.

Clostridium tertium (C. tertium) is an aero-tolerant, gram-positive, endospore-forming, and non-exotoxin-producing bacillus that has colonized the gastrointestinal tract of animals and humans. It is considered a rare pathogen of humans, possibly because of its low virulence. Most C. tertium infections in the reviewed literatures were predominately reported among neutropenic hosts with hematological malignancies. A 66-year-old female patient with a past medical history of type II diabetes mellitus and chronic obstructive pulmonary disease was admitted with coronavirus disease 2019 (COVID-19) that initially required non-invasive ventilation. The patient developed septic shock due to C. tertium bacteremia. Computed tomography of the abdomen depicted free intraperitoneal gas and sigmoid colon perforation. Exploratory laparotomy revealed perforated sigmoid diverticulitis, and Hartmann's procedure was performed. The patient received a prolonged course of susceptibility-guided antibiotics to clear C. tertium bacteremia. The authors described a rare case of C. tertium bacteremia as a marker of underlying perforated colonic diverticulitis in a non-neutropenic patient with COVID-19 that necessitated operative procedure intervention for primary source control and an extended course of targeted antibiotic therapy to treat the Clostridial infection. Our case reaffirmed the available literature that suggested the presence of C. tertium bacteremia in non-neutropenic patients raises suspicion of an associated gastrointestinal tract pathology that should warrant a diagnostic workup to identify the infection source culprit.

Medical decision making : an international journal of the Society for Medical Decision Making, 42(8):1010-1026.

BACKGROUND: Electronic health records (EHRs) offer opportunities for comparative effectiveness research to inform decision making. However, to provide useful evidence, these studies must address confounding and treatment effect heterogeneity according to unmeasured prognostic factors. Local instrumental variable (LIV) methods can help studies address these challenges, but have yet to be applied to EHR data. This article critically examines a LIV approach to evaluate the cost-effectiveness of emergency surgery (ES) for common acute conditions from EHRs.

METHODS: This article uses hospital episodes statistics (HES) data for emergency hospital admissions with acute appendicitis, diverticular disease, and abdominal wall hernia to 175 acute hospitals in England from 2010 to 2019. For each emergency admission, the instrumental variable for ES receipt was each hospital's ES rate in the year preceding the emergency admission. The LIV approach provided individual-level estimates of the incremental quality-adjusted life-years, costs and net monetary benefit of ES, which were aggregated to the overall population and subpopulations of interest, and contrasted with those from traditional IV and risk-adjustment approaches.

RESULTS: The study included 268,144 (appendicitis), 138,869 (diverticular disease), and 106,432 (hernia) patients. The instrument was found to be strong and to minimize covariate imbalance. For diverticular disease, the results differed by method; although the traditional approaches reported that, overall, ES was not cost-effective, the LIV approach reported that ES was cost-effective but with wide statistical uncertainty. For all 3 conditions, the LIV approach found heterogeneity in the cost-effectiveness estimates across population subgroups: in particular, ES was not cost-effective for patients with severe levels of frailty.

CONCLUSIONS: EHRs can be combined with LIV methods to provide evidence on the cost-effectiveness of routinely provided interventions, while fully recognizing heterogeneity.

HIGHLIGHTS: This article addresses the confounding and heterogeneity that arise when assessing the comparative effectiveness from electronic health records (EHR) data, by applying a local instrumental variable (LIV) approach to evaluate the cost-effectiveness of emergency surgery (ES) versus alternative strategies, for patients with common acute conditions (appendicitis, diverticular disease, and abdominal wall hernia).The instrumental variable, the hospital's tendency to operate, was found to be strongly associated with ES receipt and to minimize imbalances in baseline characteristics between the comparison groups.The LIV approach found that, for each condition, there was heterogeneity in the estimates of cost-effectiveness according to baseline characteristics.The study illustrates how an LIV approach can be applied to EHR data to provide cost-effectiveness estimates that recognize heterogeneity and can be used to inform decision making as well as to generate hypotheses for further research.

Effectiveness of emergency surgery for five common acute conditions: an instrumental variable analysis of a national routine database.

Anaesthesia, 77(8):865-881.

The effectiveness of emergency surgery vs. non-emergency surgery strategies for emergency admissions with acute appendicitis, gallstone disease, diverticular disease, abdominal wall hernia or intestinal obstruction is unknown. Data on emergency admissions for adult patients from 2010 to 2019 at 175 acute National Health Service hospitals in England were extracted from the Hospital Episode Statistics database. Cohort sizes were: 268,144 (appendicitis); 240,977 (gallstone disease); 138,869 (diverticular disease); 106,432 (hernia); and 133,073 (intestinal obstruction). The primary outcome was number of days alive and out of hospital at 90 days. The effectiveness of emergency surgery vs. non-emergency surgery strategies was estimated using an instrumental variable design and is reported for the cohort and pre-specified sub-groups (age, sex, number of comorbidities and frailty level). Average days alive and out of hospital at 90 days for all five cohorts were similar, with the following mean differences (95%CI) for emergency surgery minus non-emergency surgery after adjusting for confounding: -0.73 days (-2.10-0.64) for appendicitis; 0.60 (-0.10-1.30) for gallstone disease; -2.66 (-15.7-10.4) for diverticular disease; -0.07 (-2.40-2.25) for hernia; and 3.32 (-3.13-9.76) for intestinal obstruction. For patients with 'severe frailty', mean differences (95%CI) in days alive and out of hospital for emergency surgery were lower than for non-emergency surgery strategies: -21.0 (-27.4 to -14.6) for appendicitis; -5.72 (-11.3 to -0.2) for gallstone disease, -38.9 (-63.3 to -14.6) for diverticular disease; -19.5 (-26.6 to -12.3) for hernia; and - 34.5 (-46.7 to -22.4) for intestinal obstruction. For patients without frailty, the mean differences (95%CI) in days alive and out of hospital were: -0.18 (-1.56-1.20) for appendicitis; 0.93 (0.48-1.39) for gallstone disease; 5.35 (-2.56-13.28) for diverticular disease; 2.26 (0.37-4.15) for hernia; and 18.2 (14.8-22.47) for intestinal obstruction. Emergency surgery and non-emergency surgery strategies led to similar average days alive and out of hospital at 90 days for five acute conditions. The comparative effectiveness of emergency surgery and non-emergency surgery strategies for these conditions may be modified by patient factors.

A Rare Presentation of Recurrent Diverticulitis in a Patient with Ulcerative Colitis.

European journal of case reports in internal medicine, 9(4):003271.

UNLABELLED: Diverticulitis and ulcerative colitis (UC) are two separate colonic pathologies with different underlying mechanisms. Diverticulosis involves herniation of mucosal and submucosal tissue through muscular tissue in response to increased intraluminal pressure. In contrast, it is believed that the muscular tone in patients with UC is reduced due to chronic inflammatory changes. Thus, it has been reported that there may be an inverse relationship between the presence of diverticulosis in patients with UC, in that UC may possibly be protective against developing diverticular disease. Consequently, the co-presence of both pathologies is uncommon. Here we present a case in which a woman with a history of UC and recurrent diverticulitis after elective partial colectomy was admitted for recurrent acute diverticulitis. It is quite challenging to diagnose diverticulitis in ulcerative colitis patients given the usually similar presentation with abdominal pain, diarrhoea and hematochezia. A level of high suspicion is required for diagnosis.

LEARNING POINTS: Colonic diverticulitis is not commonly associated with ulcerative colitis.The diagnosis of colonic diverticulitis in the setting of ulcerative colitis is challenging and requires a high level of suspicion.

Associations of sedentary time and physical activity with adverse health conditions: Outcome-wide analyses using isotemporal substitution model.

EClinicalMedicine, 48:101424.

BACKGROUND: As one of the most common lifestyles today, sedentary behaviour is a risk factor for many health conditions. To inform potential behavioural guideline development, we aimed to estimate the theoretical effects of replacing sedentary behaviour with different intensity of physical activity on risks of 45 common non-communicable diseases (NCDs).

METHODS: A total of 360,047 participants (aged 37-73 years) in the UK Biobank free of the 45 common non-communicable diseases (NCDs) were included. Information on sedentary time (sum of television watching, computer using and driving behaviour) and physical activity (measured by International Physical Activity Questionnaire questionnaire) were collected by self-reported at baseline. Participants were followed up for 45 NCDs diagnosis according to the ICD-10 code using linkage to national health records until 2020. Isotemporal substitution models were used to investigate substituting sedentary time with light physical activity (LPA), moderate physical activity (MPA) and vigorous physical activity (VPA) after adjusting for potential confounders.

FINDING: Participants who reported > 6 h/day compared with ≤ 2 h/day sedentary time had higher risks of 12 (26.7%) of 45 NCDs, including ischemic heart disease, diabetes, chronic obstructive pulmonary disease, asthma, chronic kidney disease, chronic liver disease, thyroid disorder, depression, migraine, gout, rheumatoid arthritis and diverticular disease. Theoretically, replacing sedentary time with equivalent LPA, MPA and VPA was associated with risk reductions in 4, 6 and 10 types of NCDs, respectively. Among long sedentary time (> 6 h/day), replacing 1 h/day sedentary time with equivalent VPA showed stronger associations with 5 NCDs (diabetes, depression, chronic liver disease, diverticular disease and sleep disorder), with a larger risk reduction of 11%-31%.

INTERPRETATION: Sedentary time is associated with multiple adverse health conditions, replacing sedentary time with any equivalent amounts of VPA than LPA and MPA could be associated with risk reductions of more types of NCDs.

Association of frailty with outcomes after elective colon resection for diverticular disease.

Surgery, 172(2):506-511.

BACKGROUND: Frailty has been associated with greater postoperative morbidity and mortality but its impact has not been investigated in patients with diverticulitis undergoing elective colon resection. Therefore, the present study examined the association of frailty with perioperative outcomes following elective colectomy for diverticular disease.

METHODS: The 2017-2019 American College of Surgeons-National Surgical Quality Improvement Program data registry was queried to identify patients (aged ≥18 years) undergoing elective colon resection for diverticular disease. The 5-factor modified frailty index (mFI-5) was used to stratify patients into non-frail (mFI 0), prefrail (mFI 1), and frail (mFI ≥2) cohorts. Major adverse events, surgical site infection, and postoperative ileus as well as prolonged length of stay, nonhome discharge, and unplanned readmission were evaluated using multivariable logistic models.

RESULTS: Of the 20,966 patients, 10.0% were frail. Compared to others, frail patients were generally older (non-frail: 55 years, [46-63], prefrail: 62, [54-70], frail: 64, [57-71]) and more commonly female (non-frail: 53.1%, prefrail: 58.6, frail: 64.4, P < .001). Frail patients more frequently underwent open colectomy and stoma creation compared with others. Frailty was associated with greater adjusted odds of major adverse event (adjusted odds ratio 1.25, 95% confidence interval 1.06-1.48), surgical site infection (adjusted odds ratio 1.28, 95% confidence interval 1.06-1.54), and postoperative ileus (adjusted odds ratio 1.59, 95% confidence interval 1.27-1.98). Similarly, frailty portended greater odds of prolonged length of stay, nonhome discharge, and unplanned readmission.

CONCLUSION: Frailty as defined by the mFI-5 was associated with greater morbidity and hospital resource use. Deployment of frailty instruments may augment traditional risk calculators and improve patient selection for elective colectomy.

Right-sided diverticulitis in a Western population.

International journal of colorectal disease, 37(6):1251-1256.

BACKGROUND: While left-sided colonic diverticular disease is common in Western Caucasian populations, right-sided colonic disease (RCD) is rare. The present study aimed to determine the rate of RCD and to identify the symptoms, clinical features, treatment, and outcomes in a single medical center in Israel.

METHODS: Data for this descriptive retrospective analysis were collected from the electronic medical records of all patients diagnosed with colonic diverticulitis from January 2014 to June 2019.

RESULTS: During the study period, 1000 patients with diverticulitis were admitted to our institution, of which 99 had RCD (10%). Mean age was 50.2 years. The main presenting symptom was acute onset of right-sided abdominal pain. The diagnosis was made almost exclusively by computed tomography scan and the cecum was the most frequent site. The clinical course was benign, without major complications for most patients (90.1%). Nine patients presented with abscess (n = 1), covered perforation (n = 7), or partial obstruction (n = 1). All patients were treated with intravenous antibiotics with a median length of hospital stay of 3 days and a median 9 days of antibiotic treatment. Only 1 patient underwent diagnostic laparoscopy due to suspected intestinal perforation. Three patients experienced disease recurrence after a median follow-up of 48 months. Upon recovery, half of the patients underwent colonoscopy; no further pathology was found in any.

CONCLUSION: Unlike sigmoid colon diverticulitis, the incidence of RCD in Western populations is low. The clinical course is benign, with conservative treatment without the need for surgery. The complication and recurrence rates are low.

Venous thromboembolism in chronic gastrointestinal disorders.

Expert review of gastroenterology & hepatology, 16(5):437-448.

INTRODUCTION: Chronic gastrointestinal disorders (including autoimmune gastritis, celiac disease, inflammatory bowel disease, and diverticular disease) are highly prevalent disorders, that may be associated with unpredictable, life-threatening complications, such as thromboembolic events. Venous thromboembolism (VTE) is one of the major causes of morbidity and mortality worldwide. Several conditions, including cancer, major trauma, surgery, prolonged immobilization, are well-established risk factors for VTE. Over the past decade, chronic inflammation has also been identified as an independent risk factor for VTE due to the prothrombotic effects of inflammatory cytokines and oxidative stress on the coagulation cascade. Other several mechanisms were shown to be associated with a higher incidence of VTE in patients with gastrointestinal disorders.

AREAS COVERED: We critically discuss the latest insights into the mechanisms responsible for thromboembolic manifestations in chronic gastrointestinal disorders, also focusing on the recognition of risk factors and treatment.

EXPERT OPINION: The occurrence of thrombotic complications is underestimated in patients with chronic gastrointestinal disorders. Identifying potential risk factors and concomitant predisposing conditions and to prevent VTE and guide treatment require a multidisciplinary approach, and this is critically important for clinicians, in order to provide the best care for such patients.

Nationwide Analysis of Hospital Admissions Prior to Hartmann's Procedure for Acute Diverticulitis.

The American surgeon, 88(9):2148-2157.

INTRODUCTION: Diverticular disease is one of the most common gastrointestinal diseases that require hospital admission. This study aims to identify trends in prior hospital admissions for patients that ultimately require a Hartmann's procedure for complicated diverticulitis.

METHODS: The Nationwide Readmissions Database for 2010-2014 was queried for all patients aged 18 years or older admitted with an ICD-9 code for colonic diverticulitis and end colostomy creation. Patients with prior hospital admissions were identified. The primary outcome was mortality after Hartmann's procedure. Secondary outcomes were prior hospital admission and previous percutaneous drain placement. Multivariable logistic regression was performed to control for confounding factors for each outcome and results were weighted for national estimates.

RESULTS: There were 90,162 patients admitted with complicated diverticulitis requiring end colostomy creation. Prior hospital admissions were found in 28.1% (n = 25,307) and 14.4% (n = 12,947) had a previous percutaneous drain placed during a prior admission. The overall mortality rate was 5.9% (n = 5314) after Hartman's procedure. The mortality rate for patients with prior hospital admissions was 8.7% (P < .001), and the mortality rate for patients with previous percutaneous drain placement was 4.3% (P < .001). After controlling for confounding factors including comorbidities, patients with prior admission had an increased risk of mortality (OR 1.48 [1.40-1.58], P < .001) and patients with previous percutaneous drain placement had a decreased risk of mortality (OR .66 [.60-.72], P < .001).

CONCLUSIONS: Hospitalizations for complications of diverticulitis are a costly burden to our healthcare system. By identifying those patients at high risk for readmission and emergency surgery, perioperative outcomes may be improved.

Appendiceal Diverticulitis Presenting as Acute Appendicitis and Diagnosed After Appendectomy.

Cureus, 14(3):e23050.

Introduction Diverticular disease of the appendix (DDA) is a rare appendiceal pathology. It is usually present similar to acute appendicitis. Because of its rarity, the DDA is poorly comprehended. This study evaluates the incidence, clinical and pathological characteristics of appendiceal diverticulitis diagnosed after appendectomy. Methods We performed a retrospective analysis of patients who underwent appendectomy between January 2016 and January 2022 at the Istanbul Sultanbeyli State Hospital General Surgery Clinic. The following parameters were analyzed: age and gender, preoperative diagnosis, laboratory results, radiological imaging findings, surgical technique, histopathological examination of specimens, and complications. Results A total of 1586 patients were analyzed. In the pathology, diverticular disease of the appendix was detected in 10 patients (0.63%). The DDA patients' mean age was 34.4 years, and the male to female ratio was 4:1. We detected low-grade appendiceal mucinous neoplasia in one of our patients. Conclusion Appendiceal diverticulitis is rare and usually presents as acute appendicitis. Most DDAs are detected incidentally during the postoperative period and are associated with an increased risk of appendiceal neoplasm. Appendectomy specimens should be carefully examined histopathologically to detect diverticular disease of the appendix.

A vastagbél-diverticulosis veszélyei és kezelése.

Orvosi hetilap, 163(16):614-623.

Összefoglaló. A vastagbél-diverticulosis előfordulási gyakorisága világszerte növekszik, aminek hátterében elsősorban diétás és életmódbeli változások állnak. Az esetek jelentős hányadában a vastagbél-diverticulosis semmiféle panaszt nem okoz, véletlenül fedezik fel, így kezelést sem igényel. Tünetek az esetek mintegy 25%-ában jelentkeznek: ez az ún. diverticularis betegség, melynek különböző súlyosságú és lefolyású formái ismertek. A 2000-es évek elejétől a diverticulosis kialakulásában szerepet játszó patofiziológiai folyamatok - úgymint a genetikai háttér, az alacsony fokú krónikus gyulladás és a béldysbiosis jelenléte - jobb megértése elősegítette a megelőzés, a diagnosztika és a kezelés eszközeinek fejlődését. Főbb megállapítások: A tüneteket okozó szövődménymentes diverticulosis elkülönítése az irritábilisbél-szindrómától egyértelműen kihívást jelent. Az akut diverticulitis előfordulási gyakorisága alacsonyabb, mint korábban feltételezték. A képalkotóknak, különösen a hasi komputertomográfiának a szerepe előtérbe került a gyors és megfelelő diagnózis felállításában és a betegség súlyosságának meghatározásában. A magas rosttartalmú étrend az egészséges táplálkozás fontos része, ugyanakkor nincs bizonyíték arra, hogy gyorsítaná az akut diverticulitis során a felgyógyulást, vagy megelőzné annak kiújulását. Újabban vitatják azt a hagyományos álláspontot, miszerint a szövődménymentes akut diverticulitist mindenképpen antibiotikummal kell kezelni, és kórházi felvételt igényel. Akut diverticulitis esetén nem ajánlott kolonoszkópia végzése a perforációveszély miatt. Elektív kolonoszkópia 6 héttel később javasolt, colorectalis carcinoma kizárására, amennyiben 3 éven belül nem került rá sor. Bizonyos esetekben a rutinkolonoszkópia azonban el is hagyható. A szövődményes akut diverticulitis kezelése során nem mindig szükséges sürgős sebészeti beavatkozás. A műtétre szoruló, hemodinamikailag stabil, immunkompetens betegekben diverticulumperforáció és diffúz peritonitis esetén pedig a reszekció és a primer anasztomóziskészítés egyre inkább teret nyer a Hartmann-műtéttel szemben. A szerzők a jelen összefoglalóval a diverticulosis korszerű, egyénre szabott ellátását kívánják elősegíteni a mindennapi klinikai gyakorlatban. Orv Hetil. 2022; 163(16): 614-623. Summary. The prevalence of colonic diverticulosis is growing worldwide due to dietary and lifestyle changes. Colonic diverticulosis does not cause any complaints in a significant proportion of individuals; therefore, it is usually diagnosed by accident and does not require any treatment. Diverticular disease, which constitutes about 25% of the cases, is associated with presenting symptoms, and has various forms based on the course and severity of the disease. From the early 2000s, the better understanding of the pathophysiologic pathways which play a role in the development of the diverticular disease (genetic background, low-grade chronic inflammation and intestinal dysbiosis) promoted prevention, diagnostics and finding treatment options. The main conclusions: It is a challenge to distinguish uncomplicated but symptomatic diverticular disease from irritable bowel syndrome. The prevalence of acute diverticulitis is lower than it was previously assumed. The role of diagnostic imaging, mainly abdominal computer tomography, has become more important to aid the rapid and correct diagnosis of acute diverticulitis and to determine its severity. Although a high-fiber diet may be recommended for general health purposes, there is little evidence that it benefits recovery during acute diverticulitis episodes or prevents recurrent episodes. Traditional antibiotic therapy as the mainstay of treatment of acute uncomplicated diverticulitis such as routine hospital admission has been challenged recently. In an acute episode of diverticulitis, performing colonoscopy should be avoided as it is associated with an increased risk of colonic perforation. If there was no screening colonoscopy within 3 years, it is strongly recommended at least 6 weeks after the acute episode to exclude colorectal carcinoma. Routine colonoscopy may be omitted in certain cases. Complicated acute diverticulitis should not necessarily be treated by emergency surgery. In the case of hemodynamically stable and immunocompetent patients, resection with primary anastomosis may be preferred over a Hartmann's procedure for the treatment of perforated diverticulitis and diffuse peritonitis. With this review, the authors intend to facilitate providing up-to-date and customized treatment of diverticular disease in the daily practice. Orv Hetil. 2022; 163(16): 614-623.

Lactobacillus paracasei CNCM I 1572: A Promising Candidate for Management of Colonic Diverticular Disease.

Journal of clinical medicine, 11(7):.

Diverticular disease (DD) is a common gastrointestinal condition. Patients with DD experience a huge variety of chronic nonspecific symptoms, including abdominal pain, bloating, and altered bowel habits. They are also at risk of complications such as acute diverticulitis, abscess formation, hemorrhage, and perforation. Intestinal dysbiosis and chronic inflammation have recently been recognized as potential key factors contributing to disease progression. Probiotics, due to their ability to modify colonic microbiota balance and to their immunomodulatory effects, could present a promising treatment option for patients with DD. Lactobacillus paracasei CNCM I 1572 (LCDG) is a probiotic strain with the capacity to rebalance gut microbiota and to decrease intestinal inflammation. This review summarizes the available clinical data on the use of LCDG in subjects with colonic DD.

Segmental Colitis Associated With Diverticulosis Masquerading as Polyploid-Appearing Mucosa in the Rectosigmoid Area on Endoscopy and as Focal Thickening on Imaging.

Cureus, 14(3):e22930.

Segmental colitis associated with diverticulosis (SCAD) is an inflammatory disease affecting segments of the large bowel with diverticular disease. SCAD presents several challenges in diagnoses and treatment because it often mimics a range of disorders including inflammatory bowel disease and malignancy. Here, we present the case of a 72-year-old man with lower abdominal pain and bloody stools whose initial abdominal workup showed nonspecific large bowel thickening and concerns for malignancy. Ultimately, the patient was diagnosed with mild SCAD and treated conservatively with a resolution of symptoms. He had no symptoms at the three-month and 1-year follow-ups. This case highlights the importance of including SCAD in the initial differential diagnosis to allow accurate identification and treatment.

Jejunal diverticulosis - A case series and literature review.

Annals of medicine and surgery (2012), 75:103477.

INTRODUCTION: Scant literature is available regarding in vivo jejunal diverticulosis, in part due to its typically asymptomatic course. This is made more difficult by the difficulty in establishing its diagnosis. This case series examines a number of patients presenting to our hospital with jejunal diverticular disease, and their varying clinical courses.

METHODS: A number of cases that had presented to our hospital with jejunal diverticulosis were reviewed retrospectively in keeping with PROCESS guidelines. Their presentations, investigations, and management rationale are discussed in brief.

DISCUSSION: The presentation of jejunal diverticulosis is varies significantly along a spectrum, with a number of symptoms similar to other common intra-abdominal pathologies. The imaging modalities of choice are a barium small bowel series, CT scans, and enteroclysis, varying in sensitivity and complexity. Decision making with regards to operative vs. non-operative management is typically in line with that of colonic diverticulosis, though no strict guidelines have been established.

CONCLUSION: Jejunal diverticulosis is an uncommon, with scarce data available on the appropriate investigation and management pathways. Its presentation is difficult to differentiate from other intra-abdominal pathology, and its investigations either poorly sensitive or costly and technically challenging. The general consensus on its management is similar to that of colonic diverticula, though more research needs is warranted.

Small bowel volvulus is a rare occurrence in adults as it most commonly occurs within the first year of life as a complication of malrotation, an embryologic anomaly. When occurring in any age group, restriction of blood flow can lead to ischemia and eventual infarction of bowel making any suspected volvulus a surgical emergency. We present a case of a middle-aged patient with acute small bowel obstruction with small bowel volvulus. Following oral administration of water-soluble contrast as part of a single contrast upper gastrointestinal tract (UGI) study and changes in positioning, the patient experienced spontaneous resolution of the small bowel volvulus.

Severe Obesity Contributes to Worse Outcomes After Elective Colectomy for Chronic Diverticular Disease.

Journal of gastrointestinal surgery : official journal of the Society for Surgery of the Alimentary Tract, 26(7):1472-1481.

BACKGROUND: Both obesity and chronic diverticular disease (DD) are on the rise. Understanding surgical outcomes for patients with obesity undergoing colectomy for DD is imperative to improve care and minimize complications. Our objective was to investigate the impact of obesity on outcomes after elective colectomy specifically for chronic DD.

METHODS: Using the American College of Surgeons National Surgical Quality Improvement Program database from 2012 to 2018, patients who underwent elective colectomy for chronic DD were grouped into four body mass index categories. Baseline characteristics, surgical approach and procedure, and 30-day morbidity and mortality were assessed.

RESULTS: Of 24,559 patients, 21.7% were of normal weight, 35.8% were overweight, 35.9% were obese, and 6.6% were severely obese. Patients with severe obesity were younger, more functionally dependent, and had more comorbidities (all P [Formula: see text] 0.0001). Patients with severe obesity were more likely to have unplanned conversion to open surgery from laparoscopic and robotic approaches (AOR 2.15, 95% CI 1.24-3.70). Obesity class did not significantly affect the type of surgical procedure patients underwent (Hartmann's, colectomy with anastomosis and diversion, or colectomy with primary anastomosis). There were increased odds of any perioperative complications (AOR 1.43, 95% CI 1.19-1.71) and non-home discharge (AOR 2.39, 95% CI 1.59-3.57) in patients with severe obesity compared to normal weight patients.

CONCLUSIONS: Obesity is associated with poorer outcomes in patients undergoing elective colectomy for chronic DD. Futures studies to examine the impact of preemptive weight loss to improve outcomes after elective colectomy for chronic sequelae of DD are needed.

Risk factors of re-bleeding within a year in colonic diverticular bleeding patients.

DEN open, 2(1):e22.

BACKGROUND/AIMS: Although colonic diverticular bleeding (CDB) is common, few reports have described the effects of antithrombotic agents (ATs) on CDB. This study aimed to clarify the risk factors of re-bleeding within a year in CDB patients.

METHODS: We retrospectively analyzed the risk of re-bleeding in CDB patients. Among 324 patients who were hospitalized for acute lower gastrointestinal bleeding at our institution during the period from 2015 to 2019, we used 76 patients who were diagnosed as CDB. Risk factors for re-bleeding were determined by Cox proportional hazard models.

RESULTS: Of 76 patients analyzed, 32 were taking ATs, nine of whom were taking multiple agents. Twenty-six patients re-bled within a year. Compared with the patients without re-bleeding, patients with re-bleeding within a year had been treated by antithrombotic therapy more frequently (62% vs. 32%, p = 0.013). Cox proportional hazard model revealed that treatment with ATs (hazard ratio 3.89, 95% confidence interval 1.53-10.74, p = 0.004) was an independent risk factor for re-bleeding within a year.

CONCLUSION: ATs were found to be an independent risk factor related to re-bleeding within a year in patients with CDB.

Minerva gastroenterology, 68(2):216-222.

BACKGROUND: Symptomatic uncomplicated diverticular disease (SUDD) is a recognized clinical condition characterized by abdominal pain and changes in bowel habits, attributed to diverticula but without macroscopic signs of diverticulitis. There is no consensus about the management of these patients. Enteroflegin[®], an association of natural active ingredients, could be effective in the treatment of those patients.

METHODS: We conducted a retrospective observational study to evaluate the performances of Enteroflegin[®] in patients with SUDD. Patients were treated with Enteroflegin[®] 2 cp/day for 10 days per month for 6 months. Primary endpoint was the clinical remission rate, defined as the absence of any symptoms; secondary endpoints were the impact of the treatment on reduction of symptoms, on fecal calprotectin (FC) expression, and the prevention of acute diverticulitis.

RESULTS: Three hundred and fifty patients were retrospectively enrolled (183 males, median age 64 years, IQR 54-70). Enteroflegin[®] was effective in inducing remission in 9.34% and 17.64% of patients at 3 and 6 months respectively (P<0.001). Reduction of symptoms occurred in 92.3% and in 85.3% of patients at 3 and 6 months respectively (P<0.001), and symptoms' recurrence or worsening was recorded in only 1.71% of patients during the follow-up. FC expression dropped from 181.3 μg/g at baseline to 100.2 μg/g (P<0.001) and to 67.9 μg/g (P<0.001) at 3 and 6 months of follow-up respectively. No adverse event was recorded during the follow-up. Finally, acute diverticulitis occurred in just 2% of patients during the follow-up.

CONCLUSIONS: Enteroflegin[®] seems to be an effective nutraceutical compound in obtaining remission and symptom relief in SUDD patients. Further randomized, placebo-controlled clinical trials are needed to confirm these preliminary data.

Oxidative imbalance and muscular alterations in diverticular disease.

Digestive and liver disease : official journal of the Italian Society of Gastroenterology and the Italian Association for the Study of the Liver, 54(9):1186-1194.

BACKGROUND: It is still a matter of debate if neuromuscular alterations reflect a primary event in diverticular disease (DD).

AIMS: This study aimed to assess colonic wall layers from both stenotic and non-stenotic complicated DD, bio-phenotypic alterations, inflammatory and oxidative status.

METHODS: A systematic analysis of colonic specimens obtained from stenotic and non-stenotic DD specimens was conducted and compared with controls. Biological activity and qPCR analysis were performed on longitudinal and circular muscles. Western blot analysis was performed throughout colonic wall layers to quantify oxidative and inflammatory markers.

RESULTS: A homogenous increase in oxidative stress was observed through all the layers, which were more sharpened in the longitudinal muscle for a loss in antioxidant defenses. In both stenotic and non-stenotic colon, the longitudinal muscle presented an impaired relaxation and a cellular phenotypic switch driven by transforming growth factor-β with an increase in mRNA expression of collagen Iα and a decrease in myosin heavy chain. The circular muscle, as the mucosa, was less affected by molecular alterations. No peculiar increase in inflammatory markers was observed.

CONCLUSION: A longitudinal colonic myopathy is present in DD, independently from the disease stage associated with an oxidative imbalance that could suggest new therapeutic strategies.

The Dilemma of the Level of the Inferior Mesenteric Artery Ligation in the Treatment of Diverticular Disease: A Systematic Review of the Literature.

Journal of clinical medicine, 11(4):.

BACKGROUND AND AIM: Although sigmoidectomy is a well-standardized procedure for diverticular disease, there are still unclear areas related to the varying morphology and vascular supply of the sigmoid colon. The level of vascular ligation could affect the functional outcomes of patients operated on for diverticular disease. The aim of this review is to primarily evaluate sexual, urinary and defecatory function outcomes, as well as postoperative results, in patients who underwent surgery for diverticular disease, with or without inferior mesenteric artery (IMA) preservation.

MATERIALS AND METHODS: The MEDLINE/PubMed, WOS and Scopus databases were interrogated. Comparative studies including patients who underwent sigmoidectomy for diverticular diseases were considered. Bowel function, genitourinary function, anastomotic leak, operation time, conversion to open surgery, anastomotic bleeding, bowel obstruction were the main items of interest.

RESULTS: Twelve studies were included in the review, three randomized and nine comparative studies. Bowel and genitourinary function are not differently affected by the level of vascular ligation. The site of ligation of IMA did not influence the rate of functional complications, anastomotic leak and bleeding. Of note, the preservation of IMA is associated with a higher conversion rate and longer operative time.

CONCLUSIONS: Despite the heterogeneity of patient groups, and although the findings should be interpreted with caution, functional and clinical outcomes after sigmoidectomy for diverticular disease do not seem to be affected by the level of vascular ligation as long as the IMA is ligated far from its origin.

Diversion colitis in inflammatory bowel disease (IBD) is distinct from that in non-IBD: Reappraisal of diversion colitis.

Human pathology, 123:31-39.

The significant histologic overlap between diversion colitis and inflammatory bowel disease (IBD) poses a diagnostic challenge. We aimed to identify histologic features that are characteristic of diverted colon segments among patients with IBD and compare them with histologic features identified in IBD colectomies. Archived slides from resected diverted colon segments from patients with (n = 79) and without (n = 80) IBD and the corresponding prior colectomies (n = 52) of the IBD patients were reviewed. Clinical and endoscopic data were collected, and a series of histologic features were evaluated and graded. Compared to the non-IBD group, IBD patients were more likely to be symptomatic and present with abnormal endoscopic findings (P < .05). The severity of inflammatory activity, crypt architectural distortion, mucosal atrophy, transmural inflammation, intramucosal lymphoid aggregates (IMLAs), and transmural lymphoid aggregates (TMLAs) were significantly greater in diverted segments in IBD cases than controls (P < .001). The severity of inflammatory activity, IMLAs, TMLAs, and transmural inflammation and the presence of ulcer(s) in the diverted colon segments of IBD patients were associated with the histologic features reflective of IBD activity such as inflammatory activity, transmural inflammation and ulcer(s) in the preceding colectomies (P < .05). Diversion colitis developing in the setting of IBD is endoscopically and histologically distinct from that observed among individuals without IBD. Inflammatory activity, presence of ulcer(s), IMLAs, TMLAs, and transmural inflammation in diverted colon segments of IBD patients may, in part, reflect the severity of underlying IBD rather than pure diversion colitis.

Early elective versus elective sigmoid resection in diverticular disease: not only timing matters-a single institutional retrospective review of 133 patients.

Langenbeck's archives of surgery, 407(4):1613-1623.

PURPOSE: The optimal timing of elective surgery in patients with the colonic diverticular disease remains controversial. We aimed to analyze the timing of sigmoidectomy in patients with diverticular disease and its influence on postoperative course with respect to the classification of diverticular disease (CDD).

METHODS: Patients who underwent elective laparoscopic sigmoidectomy were retrospectively enrolled and subdivided into two groups based on the time interval between the last attack and surgery: group A, early elective (≤ 6 weeks), and group B, elective (> 6 weeks). Multivariate regression models were used to identify factors which predict conversion to laparotomy, postoperative course, and length of hospital stay.

RESULTS: A total of 133 patients (group A (n = 88), group B (n = 45)) were included. Basic demographic data did not differ between groups except for a higher rate of diabetes in group B (p = 0.009). The conversion rate was significantly higher in group A in comparison to group B (group A vs. group B: n = 23 (26.1%) vs. n = 3 (6.7%), p = 0.007). Logistic regression analysis revealed the timing of surgery and CDD stage as significant predictors for intraoperative conversion. Moreover, the postoperative course was influenced by high age as well as intraoperative conversion and length of hospital stay by conversion, preoperative CRP levels, and elective surgery.

CONCLUSIONS: Both, timing of surgery and the disease stage, influence the conversion rates in laparoscopic sigmoidectomy for diverticular disease. Accordingly, patients with complicated acute or chronic sigmoid diverticulitis should be operated in the inflammation-free interval.

Type 2 diabetes and risk of diverticular disease: a Danish cohort study.

BMJ open, 12(2):e059852.

OBJECTIVES: To investigate the association between type 2 diabetes and risk of diverticular disease. Unlike previous studies, which have found conflicting results, we aimed to distinguish between diabetes types and adjust for modifiable risk factors.

DESIGN: Observational cohort study.

SETTING: Population-based Danish medical databases, covering the period 2005-2018.

PARTICIPANTS: Respondents of the 2010 or the 2013 Danish National Health Survey, of which there were 15 047 patients with type 2 diabetes and 210 606 patients without diabetes.

Hazard ratios (HRs) for incident hospital diagnosis of diverticular disease adjusted for survey year, sex, age, body mass index (BMI), physical activity intensity, smoking behaviour, diet and education based on Cox regression analysis. As latency may affect the association between type 2 diabetes and diverticular disease, patients with type 2 diabetes were stratified into those with <2.5, 2.5-4.9 and ≥5 years duration of diabetes prior to cohort entry.

RESULTS: For patients with and without diabetes the incidence rates of diverticular disease were 0.76 and 0.54 events per 1000 person years, corresponding to a crude HR of 1.08 (95% CI 1.00 to 1.16) and an adjusted HR of 0.88 (95% CI 0.80 to 0.96). The HR was lower among patients with ≥5 years duration of diabetes (adjusted HR: 0.76, 95% CI 0.67 to 0.87) than among those with 2.5-4.9 years or <2.5 years duration.

CONCLUSION: We found that patients with type 2 diabetes had a higher incidence rate of diverticular disease compared with patients without diabetes. However, after adjustment for modifiable risk factors, driven by BMI, type 2 diabetes appeared to be associated with a slightly lower risk of diverticular disease. Lack of adjustment for BMI may partially explain the conflicting findings of previous studies.

Diverticulosis Is Associated With Internal Hemorrhoids on Colonoscopy: Possible Clues to Etiology.

Clinical gastroenterology and hepatology : the official clinical practice journal of the American Gastroenterological Association [Epub ahead of print].

Hemorrhoids are a common but poorly understood gastrointestinal condition.[1] Bowel habits and fiber consumption are frequently cited as risk factors for hemorrhoids, but research has been inconclusive.[2] Recent genome-wide association studies (GWAS) have suggested an association between diverticular disease and hemorrhoids.[3] We sought to investigate the association between colonic diverticulosis and internal hemorrhoids to validate the prediction from the GWAS.

Risk factors for short-term re-bleeding in patients with colonic diverticular bleeding: a multicenter retrospective study.

Scandinavian journal of gastroenterology [Epub ahead of print].

BACKGROUND AND AIM: Few studies have evaluated risk factors for short-term re-bleeding in patients with colonic diverticular bleeding (CDB). We aimed to reveal risk factors for re-bleeding within a month in patients with CDB.

METHODS: We retrospectively analyzed clinical course of patients with CDB diagnosed at 10 institutions between 2015 and 2019. Risk factors for re-bleeding within a month were assessed by Cox proportional hazards models.

RESULTS: Among 370 patients, 173 (47%) patients had been under the use of antithrombotic agents (ATs) and 34 (9%) experienced re-bleeding within a month. Multivariate analysis revealed that the use of ATs was an independent risk factor for re-bleeding within a month (HR 2.38, 95% CI 1.10-5.50, p = .028). Furthermore, use of multiple ATs and continuation of ATs were found to be independent risk factors for re-bleeding within a month (HR 3.88, 95% CI 1.49-10.00, p = .007 and HR 3.30, 95% CI 1.23-8.63, p = .019, respectively). Two of 370 patients, who discontinued ATs, developed thromboembolic event.

CONCLUSIONS: Use of ATs was an independent risk factor for short-term re-bleeding within a month in patients with CDB. This was especially the case for the use of multiple ATs and continuation of ATs. However, discontinuation of ATs may increase the thromboembolic events those patients.
