Review
Diverticulitis is a complication to the common condition diverticulosis. Uncomplicated diverticulitis has traditionally been treated with antibiotics. Risk factors for diverticulitis, however, may suggest, that the condition is inflammatory rather than infectious. The evidence on antibiotic treatment for uncomplicated acute diverticulitis suggests, that antibiotics have no effect on complications, emergency surgery, recurrence, elective colonic resections and long-term complications. The evidence is based on three randomised clinical trials on the need for antibiotics, which is summarised in this review.

<b> Objective: </b> Cecal diverticulitis may be encountered as a real etiological factor in 1/300 appendectomies. Differential diagnosis of acute appendicitis and cecal diverticulitis is crucial because of the different treatment methods. Our aim is to reveal the importance of distinguishing acute appendicitis from cecal diverticulitis. <p> <b>Methods: </b> The data of patients who were admitted to the hospital between 2015 and 2019 with the complaint of abdominal pain and then finally diagnosed with colon diverticular disease, colon diverticulitis, or acute appendicitis, analyzed retrospectively. <p><b>Results: </b> A total of 19 cecum diverticulitis patients were detected during surgery for acute appendicitis or during clinical and radiological evaluation. 1247 appendectomies were evaluated; the final diagnosis was observed as cecal diverticulitis in 5 patients (0,4%). One hundred nineteen patients diagnosed with colonic diverticulitis at admission were evaluated, while 105 (88,2%) of them had left-sided diverticulitis, 14 (11,7%) of them had solitary cecal diverticulitis. All of the solitary cecal diverticulitis patients were treated conservatively, except one patient who has Hinchey 3 diverticulitis.<p><b> Conclusion: </b> Differential diagnosis of cecum diverticulitis with acute appendicitis is important because cecum diverticulitis can be managed as conservatively in most cases. In order to prevent unnecessary surgical interventions, this importance has increased, especially during the COVID-19 pandemic period.

Meta-Analysis
PURPOSE
Antibiotics have long been recommended as a form of conservative therapy in patients with acute uncomplicated diverticulitis despite no supporting evidence. This meta-analysis aims to assess the difference in outcomes between observational therapy and antibiotics regime in patients with acute uncomplicated diverticulitis.
METHODS
Medline and Embase electronic databases were reviewed. A comparative meta-analysis in odds ratios (ORs) or mean difference (MD) was conducted using a random effects model for dichotomous and continuous outcomes, respectively. Randomized controlled trials comparing outcomes in patients with acute uncomplicated diverticulitis on observational therapy compared to antibiotics regime were selected. Outcomes of interest included all-cause mortality, complications, emergency surgery rates, length of stay, and recurrence.
RESULTS
A total of 7 articles looking at 5 different randomized controlled trials were included. A total of 2959 patients with acute uncomplicated diverticulitis comprising of 1485 patients on antibiotics therapy and 1474 patients on observational therapy were included in the comparison. We found that there was no statistically significant difference in all-cause mortality (OR = 0.98; 95% CI 0.53;1.81; p = 0.68), complications (OR = 1.04; 95% CI 0.36;3.02; p = 0.51), emergency surgery (OR = 1.24; 95% CI 0.70;2.19, p = 0.92), length of stay (M.D: -0.14, 95% CI -0.50;0.23, p < 0.001), and recurrent diverticulitis (OR 1.01; 95% CI 0.83;1.22, p < 0.91) between the two arms.
CONCLUSION
This systemic review and meta-analysis found that there is no statistically significant difference in outcomes between patients with acute uncomplicated diverticulitis who were put on observational therapy compared to the antibiotics regime. This suggests that observational therapy is an equally safe and effective therapy as compared to antibiotics therapy.

INTRODUCTION
Most lung transplant patients are older than 50 years. Complications from colonic diverticula are not uncommon, especially with chronic immunosuppression. However, limited data exist regarding the optimal management of these patients. We sought to investigate the incidence, risk factors, and outcomes of diverticulitis after lung transplant.
METHODS
We conducted a retrospective study to review patients undergoing lung transplant between 2007 and 2016 with posttransplant acute colonic diverticulitis. Patients were grouped based on medical or surgical management.
RESULTS
Of 512 transplant recipients, 17 (3.32%) developed 26 episodes of diverticulitis over a median follow-up of 39 months. Nine patients had documented diverticulosis on pretransplant colonoscopy. These patients had a higher incidence of surgical intervention for diverticulitis, were more likely to have recurrent diverticulitis, and had longer lengths of stay than patients without pretransplant diverticulosis. Six (35.3%) of 17 patients required surgery (ie, Hartmann procedure; 4 during the initial episode and 2 during their third and fourth episodes); 11 patients (64.7%) were managed with antibiotics alone. Patients in the surgical group presented earlier posttransplant ( = .004) and were on higher doses of tacrolimus ( = .03). Six (46.1%) of 13 patients with medically managed first episodes of diverticulitis experienced recurrence. No recurrence occurred after surgical management. No deaths were attributable to diverticulitis in either group.
CONCLUSIONS
Patients with pretransplant diverticulosis experienced earlier, more complicated episodes of diverticulitis posttransplant than patients without. Surgical patients received higher doses of tacrolimus and presented earlier than medical patients. Uncomplicated diverticulitis in posttransplant patients can be managed medically, even in the case of recurrent, uncomplicated disease.

Review
INTRODUCTION
Our aim was to determine the incidence of diverticulitis recurrence after sigmoid colectomy for diverticular disease.
METHODS
Consecutive patients who benefited from sigmoid colectomy for diverticular disease from January 2007 to June 2021 were identified based on operative codes. Recurrent episodes were identified based on hospitalization codes and reviewed. Survival analysis was performed and was reported using a Kaplan-Meier curve. Follow-up was censored for last hospital visit and diverticulitis recurrence. The systematic review of the literature was performed according to the PRISMA statement. Medline, Embase, CENTRAL, and Web of Science were searched for studies reporting on the incidence of diverticulitis after sigmoid colectomy. The review was registered into PROSPERO (CRD42021237003, 25/06/2021).
RESULTS
One thousand three-hundred and fifty-six patients benefited from sigmoid colectomy. Four hundred and three were excluded, leaving 953 patients for inclusion. The mean age at time of sigmoid colectomy was 64.0 + / - 14.7 years. Four hundred and fifty-eight patients (48.1%) were males. Six hundred and twenty-two sigmoid colectomies (65.3%) were performed in the elective setting and 331 (34.7%) as emergency surgery. The mean duration of follow-up was 4.8 + / - 4.1 years. During this period, 10 patients (1.1%) developed reccurent diverticulitis. Nine of these episodes were classified as Hinchey 1a, and one as Hinchey 1b. The incidence of diverticulitis recurrence (95% CI) was as follows: at 1 year: 0.37% (0.12-1.13%), at 5 years: 1.07% (0.50-2.28%), at 10 years: 2.14% (1.07-4.25%) and at 15 years: 2.14% (1.07-4.25%). Risk factors for recurrence could not be assessed by logistic regression due to the low number of incidental cases. The systematic review of the literature identified 15 observational studies reporting on the incidence of diverticulitis recurrence after sigmoid colectomy, which ranged from 0 to 15% for a follow-up period ranging between 2 months and over 10 years.
CONCLUSION
The incidence of diverticulitis recurrence after sigmoid colectomy is of 2.14% at 15 years, and is mostly composed of Hinchey 1a episodes. The incidences reported in the literature are heterogeneous.

Review
INTRODUCTION
Diverticulitis and appendicitis are common emergency general surgical conditions. Both can be treated with antibiotics alone; however, no antibiotic regimen has been identified as superior to others. In this study, we review different antibiotic regimens and their rates of failure.
METHODS
Retrospective cohort study of patients treated empirically with antibiotics for diverticulitis or appendicitis from January 1, 2018, to December 31, 2020, at an independent academic hospital in the Midwest.
RESULTS
A total of 587 (appendicitis, n = 43; diverticulitis, n = 544) patients were included in the cohort. They were equally male (49%) and female (51%) with a median age of 59 y. Three major antibiotic classes were compared: cephalosporin + metronidazole (C + M), penicillins, and quinolone + metronidazole. Appendicitis patients were more likely to receive C + M for empiric treatment (73%, P < 0.001), while diverticulitis patients were more likely to receive quinolone + metronidazole (45%, P < 0.001). Patients empirically treated with antibiotics for appendicitis were more likely than those treated for diverticulitis to require additional antibiotics or procedure within 90 d (33% versus 13%, respectively; P = 0.005). Empiric treatment with C + M for diverticulitis was more likely to be associated with the need for additional antibiotics or procedures within 90 d than treatment with other regimens (P = 0.003). Choice of antibiotic for empiric treatment did not correlate with death at 90 d for appendicitis or diverticulitis. Diverticulitis patients who were initially treated as inpatients and were prescribed C + M at hospital discharge had a higher rate of death than those who were prescribed the other antibiotics (P = 0.04).
CONCLUSIONS
Empiric antibiotic treatment of appendicitis is more likely to be associated with additional antibiotics or procedure when compared with diverticulitis; however, antibiotic choice did not correlate with any of the other outcomes. Empiric treatment with a C + M for diverticulitis was more likely to be correlated with the need for additional antibiotics or procedure within 90 d.

Review
This article reviews epidemiological evidence of heritability and putative mechanisms in diverticular disease, with greatest attention to 3 recent studies of genetic associations with diverticular disease based on genome-wide or whole-genome sequencing studies in large patient cohorts. We provide an analysis of the biological plausibility of the significant associations with gene variants reported and highlight the relevance of ANO1, CPI-17 (aka PPP1R14A), COLQ6, COL6A1, CALCB or CALCA, COL6A1, ARHGAP15, and S100A10 to colonic neuromuscular function and tissue properties that may result in altered compliance and predispose to the development of diverticular disease. Such studies also identify candidate genes for future studies.

AIM
Immunosuppressed patients are more likely to fail nonoperative management of acute diverticulitis and have more postoperative complications than the immunocompetent. Transplant recipients form a subcategory among the immunosuppressed with unique challenges. The aim of this work is to report 30-day postoperative complications after colectomy for acute diverticulitis and success rates of nonoperative management in pre- and post-transplant patients.
METHOD
This is a retrospective cohort study at a single-institution tertiary referral centre. Patients with a history of acute diverticulitis were extracted from a database of 6152 recipients of solid-organ abdominal transplant between 2000 and 2015 and stratified by the index episode of diverticulitis: before or after solid-organ transplant surgery. Outcomes included 30-day postoperative complications and failure of nonoperative management.
RESULTS
Acute diverticulitis occurred in 93 patients, 69 (74%) posttransplant. Postcolectomy complications were higher posttransplant than pretransplant (43% vs. 13%, p = 0.04). Posttransplant status was not an independent risk factor for complications (odds ratio 3.59, 95% CI 0.79-16.31) when adjusting for sex and surgical acuity. Immediate urgent colectomy (29% vs. 31%, p = 0.84) and failure of nonoperative management (7% vs. 9%, p = 0.82) were similar. Complications occurred equally in those requiring urgent colectomy after nonoperative management and those undergoing immediate urgent colectomy.
CONCLUSION
Urgent colectomy rates are similar in solid-organ abdominal transplant recipients pre- and posttransplant. Posttransplant complication rates appear to be increased but transplant status as an independent factor is not significantly associated with an increased risk in this study cohort. These findings should be considered when counselling patients on the relative risks and benefits of surgical intervention for diverticulitis before versus after solid-organ transplantation.

Review
BACKGROUND AND AIMS
The role of the microbiota in diverticulosis and diverticular disease is underexplored. This systematic review aimed to assess all literature pertaining to the microbiota and metabolome associations in asymptomatic diverticulosis, symptomatic uncomplicated diverticular disease (SUDD), and diverticulitis pathophysiology.
METHODS
Seven databases were searched for relevant studies published up to September 28, 2022. Data were screened in Covidence and extracted to Excel. Critical appraisal was undertaken using the Newcastle Ottawa Scale for case/control studies.
RESULTS
Of the 413 papers screened by title and abstract, 48 full-text papers were reviewed in detail with 12 studies meeting the inclusion criteria. Overall, alpha and beta diversity were unchanged in diverticulosis; however, significant changes in alpha diversity were evident in diverticulitis. A similar Bacteroidetes to Firmicutes ratio compared with controls was reported across studies. The genus-level comparisons showed no relationship with diverticular disease. Butyrate-producing microbial species were decreased in abundance, suggesting a possible contribution to the pathogenesis of diverticular disease. Comamonas species was significantly increased in asymptomatic diverticulosis patients who later developed diverticulitis. Metabolome analysis reported significant differences in diverticulosis and SUDD, with upregulated uracil being the most consistent outcome in both. No significant differences were reported in the mycobiome.
CONCLUSION
Overall, there is no convincing evidence of microbial dysbiosis in colonic diverticula to suggest that the microbiota contributes to the pathogenesis of asymptomatic diverticulosis, SUDD, or diverticular disease. Future research investigating microbiota involvement in colonic diverticula should consider an investigation of mucosa-associated microbial changes within the colonic diverticulum itself.
