RESUMEN
BACKGROUND: Acute uncomplicated diverticulitis (AUD) is a common cause of acute abdominal pain. Recent guidelines advise selective use of antibiotics in AUD patients. This meta-analysis aimed to compare the effectiveness of no antibiotics vs antibiotics in AUD patients. METHODS: This review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses to identify randomized controlled trials (RCTs) involving AUD patients which compared the use of antibiotics with no antibiotics. Pooled outcome data was calculated using random effects modeling with 95% confidence intervals (CIs). RESULTS: 5 RCTs with 1934 AUD patients were included. 979 patients were managed without antibiotics (50.6%). Patients in the no antibiotic and antibiotic groups had comparable demographics (age, sex, and body mass index) and presenting features (temperature, pain score, and C-reactive protein levels). There was no significant difference in rates of complicated diverticulitis (OR: .61, 95% CI: 0.27-1.36, P = .23), abscess (OR: .51, 95% CI: .08-3.25, P = .47) or fistula (OR: .33, 95% CI: .03-3.15, P = .33) formation, perforation (OR: .98, 95% CI: .32-3.07, P = .98), recurrence (OR: .96, 95% CI: .66-1.41, P = .85), need for surgery (OR: 1.36, 95% CI: .47-3.95, P = .37), mortality (OR: 1.27, 95% CI: .14-11.76, P = .82), or length of stay (MD: .215, 95% CI: -.43-.73, P = .61) between the 2 groups. However, the likelihood of readmission was higher in the antibiotics group (OR: 2.13, 95% CI: 1.43-3.18, P = .0002). CONCLUSION: There is no significant difference in baseline characteristics, clinical presentation, and adverse health outcomes between AUD patients treated without antibiotics compared to with antibiotics.

INTRODUCTION: acute diverticulitis is one of the most frequent underlying causes behind individuals attending the Emergency Room with abdominal pain. The most widespread therapy for acute uncomplicated diverticulitis includes outpatient treatment with antibiotics; however, several publications indicate that patients can also be successfully treated without antibiotics. The results of the implementation of this more recent protocol in two hospitals in Madrid are presented. METHODS: an observational prospective study was performed. Participants were patients diagnosed with uncomplicated acute diverticulitis at two hospitals in Madrid, Hospital Universitario de Torrejón and Hospital Universitario Puerta de Hierro Majadahonda, between December 2018 and August 2021, treated on an outpatient basis without antibiotic therapy. The study group was compared with a control group, composed of patients diagnosed with uncomplicated acute diverticulitis and treated with outpatient antibiotic therapy at Hospital Universitario Puerta de Hierro between March 2015 and March 2018. RESULTS: three hundred and sixty-one patients were included, 182 in the study group and 179 in the control group. Diverticulitis was persistent in 19 patients (10.4 %) in the study group, who were not treated with antibiotics, and in five patients (2.8 %) in the control group, treated with outpatient antibiotic therapy (p = 0.004). Recurrences occurred in 23 patients (12.6 %) in the study group, and in 53 patients (29.6 %) in the control group (p < 0.0001). The analysis of the complications found no significant differences between both groups (p = 0.109). No urgent surgical intervention or mortality was recorded in the study group. CONCLUSIONS: in our environment, symptomatic non-antibiotic treatment of uncomplicated acute diverticulitis cases is safe, without showing a higher rate of complications. Although, there seems to be a worse initial symptom control.

INTRODUCTION: The incidence of colonic diverticulitis is increasing in Japan. Although antimicrobial chemotherapy is a treatment option, Japanese guidelines for diverticulosis do not recommend any antibiotic in particular and antibiotic selection is left to the discretion of the prescribing physician, who often selects antibiotics with anti-pseudomonal activity. Therefore, this study compared the efficacy of cefmetazole (CMZ) with that of tazobactam/piperacillin (TAZ/PIPC) in hospitalized Japanese immunocompetent patients with uncomplicated colonic diverticulitis. PATIENTS AND METHODS: This retrospective study included Japanese immunocompetent patients hospitalized for colonic diverticulitis between April 2019 and March 2022. Participants were divided into the CMZ and TAZ/PIPC groups. After propensity score matching, the intergroup differences in clinical outcomes, including adverse events, mortality, and re-admission rate, were ascertained. RESULTS: During the study period, 142 Japanese patients were hospitalized with community-onset colonic diverticulitis; 124 of these patients were immunocompetent. Of the 124 patients, 42 were excluded, and the CMZ and TAZ/PIPC groups comprised 62 and 20 patients, respectively. After propensity score matching, there were 16 patients in each group. There was no significant intergroup difference in the mortality and re-admission rates; however, the incidence of liver dysfunction was significantly higher (p = 0.018) in the TAZ/PIPC group. CONCLUSION: In patients with colonic diverticulitis, CMZ therapy should be selected because of the adequate clinical outcomes and lower incidence of adverse events, as this would reduce broad-spectrum antibiotic use and minimize antibiotic-resistant bacteria.

BACKGROUND: Colonic diverticular disease is common and its incidence increases with age, with uncomplicated diverticulitis being the most common acute presentation (1). This typically results in inpatient admission, placing a significant burden on healthcare services (2). We aimed to determine the safety and effectiveness of using intravenous or oral antibiotics in the treatment of uncomplicated diverticulitis on 30-day unplanned admissions, c-reactive protein (CRP), White Cell Count (WCC), pain resolution, cessation of pain medication, return to normal nutrition, and return to normal bowel function. METHODS: This single centre, 2-arm, parallel, 1:1, unblinded non-inferiority randomized controlled trial compared the safety and efficacy of oral antibiotics versus intravenous antibiotics in the outpatient treatment of uncomplicated colonic diverticulitis. Inclusion criteria were patients older than 18 years of age with CT proven acute uncomplicated colonic diverticulitis (Modified Hinchey Classification Stage 0-1a). Patients were randomly allocated receive either intravenous or oral antibiotics, both groups being treated in the outpatient setting with a Hospital in the Home (HITH) service. The primary outcome was the 30-day unplanned admission rate, secondary outcomes were biochemical markers, time to pain resolution, time to cessation of pain medication, time to return to normal function and time to return to normal bowel function. RESULTS: In total 118 patients who presented with uncomplicated colonic diverticulitis were recruited into the trial. Fifty-eight participants were treated with IV antibiotics, and 60 were given oral antibiotics. We found there was no significant difference between groups with regards to 30-day unplanned admissions or inflammatory markers. There was also no significant difference with regards to time to pain resolution, cessation of pain medication use, return to normal nutrition, or return to normal bowel function. CONCLUSION: Outpatient management of uncomplicated diverticulitis with oral antibiotics proved equally as safe and efficacious as intravenous antibiotic treatment in this randomized non-inferiority control trial.

The need for antimicrobial therapy for uncomplicated acute diverticulitis of the colon remains controversial. We conducted a systematic review of the efficacy of antimicrobial agents against this disease, including new randomized controlled trials (RCTs) reported in recent years, and evaluated their efficacy using a meta-analytic approach. RCTs were searched using PubMed, EMBASE, Google Scholar, Cochrane Library, Ichushi-Web, and eight registries. Keywords were 'colonic diverticulitis', 'diverticulitis', 'antimicrobial agents', ''antibiotics, 'complication', 'abscess', 'gastrointestinal perforation', 'gastrointestinal obstruction', 'diverticular hemorrhage', and 'fistula'. Studies with antimicrobial treatment in the intervention group and placebo or no treatment in the control group were selected by multiple reviewers using uniform inclusion criteria, and data were extracted. Prevention of any complication was assessed as the primary outcome, and efficacy was expressed as risk ratio (RR) and risk difference (RD). A meta-analysis was performed using 5 RCTs of the 21 studies that were eligible for scrutiny in the initial search and which qualified for final inclusion. Three of these studies were not included in the previous meta-analysis. Subjects included 1039 in the intervention group and 1040 in the control group. Pooled RRâ =â 0.86 (95% confidence interval, 0.58-1.28) and pooled RDâ =â -0.01 (-0.03 to 0.01) for the effect of antimicrobial agents in reducing any complications. Recurrences, readmissions, and surgical interventions did not significantly show the efficacies of using antimicrobial agents. A meta-analysis of recently reported RCTs did not provide evidence that antimicrobial therapy improves clinical outcomes in uncomplicated acute diverticulitis of the colon.

PURPOSE: Immune checkpoint inhibitors (ICIs) are efficacious for treating various malignancies. In addition to immune-related adverse events (irAEs), growing evidence suggests that ICIs might also be associated with diverticulitis. We aim to assess the clinical presentations and management of colonic diverticulitis among cancer patients after ICI treatment. METHODS: A retrospective study was conducted on ICI-treated adult cancer patients between 01/2010 and 06/2020. Patients were grouped based on when diverticulitis developed relative to ICI treatment, either before (controls) or after (cases). Patient clinical characters, treatment, and outcomes were compared between both groups. RESULTS: 77 eligible patients were included: 63 patients developed diverticulitis after ICI exposure (46 had initial episode after ICI exposure, 17 had a history of diverticulitis prior then recurred after ICI exposure), and 14 had diverticulitis before ICI exposure. Diverticulitis occurred after a median of 129 days after ICI initiation. Clinical characteristics overlapped with traditional diverticulitis. 93% of patients had symptom resolution after treatment, while 23.8% experienced complications. These patients exhibited higher rates of hospitalization (87% vs 48%, P = 0.015) and surgery/interventional radiology procedures (27% vs 0, P = 0.002), and worse overall survival (P = 0.022). History of diverticulitis was not associated with a more severe disease course. Immunosuppressants (e.g., corticosteroids) were rarely required unless for concurrent ICI-mediated colitis. CONCLUSION: Colonic diverticulitis can occur after ICI therapy at very low incidence (0.5%). Its clinical presentation, evaluation, and management are similar to traditional diverticulitis, but associated with higher complication rates requiring surgical intervention and has lower overall survival.

Objective Treatment for uncomplicated diverticulitis (UD) is not well established. We evaluated the strategy of reviewing intravenous antibiotics for hospitalized Japanese patients with UD. Methods Treatment was based on the physician's choice until August 2018; the indications for hospitalization and treatment have been standardized since September 2018. In this study, we monitored the use of intravenous antibiotics administered to patients hospitalized for UD and then reviewed the need for them on hospital day 3. We compared patients' length of antibiotic use, hospital stay, health care cost, and complications via the review strategy from September 2018 to December 2020 and via the previous physicians' choice strategy from January 2016 to August 2018. Results Two hundred and forty-seven patients were admitted to our hospital because of acute colonic diverticulitis from January 2016 to December 2020. After excluding complicated cases, 106 individuals were enrolled during the period of physician's choice; 87 were enrolled when treatment review was employed. There were no significant differences in age, sex, inflammation site, or severity during the first hospital visit. The median duration of antibiotic use was significantly reduced from 5 to 4 days (p=0.0075), with no marked increase in rates of transfer to surgery, mortality, or readmission due to recurrence. A more significant proportion of patients completed 3-day antibiotic treatment with the review strategy than with the physician's choice strategy (6.6% vs. 25.3%, p=0.0004). However, the length of hospital stay and total medical costs did not decrease. Conclusion The strategy of reviewing treatment on day 3 after hospitalization for UD safety reduced the duration of antibiotic use, but the hospital stay and health care costs did not decrease.

The American College of Physicians (ACP) developed this guideline to provide clinical recommendations on the diagnosis and management of acute left-sided colonic diverticulitis in adults. This guideline is based on current best available evidence about benefits and harms, taken in the context of costs and patient values and preferences. The ACP Clinical Guidelines Committee (CGC) developed this guideline based on a systematic review on the use of computed tomography (CT) for the diagnosis of acute left-sided colonic diverticulitis and on management via hospitalization, antibiotic use, and interventional percutaneous abscess drainage. The systematic review evaluated outcomes that the CGC rated as critical or important. This guideline was developed using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) methodology.

BACKGROUND: The purpose of this study was to determine if observational therapy is noninferior to antibiotics for acute uncomplicated diverticulitis according to clinically relevant margins. METHODS: MEDLINE, EMBASE, and Cochrane were systematically searched by 2 independent reviewers to identify comparative studies of observational therapy versus antibiotics for acute uncomplicated diverticulitis. Non-inferiority margins (ΔNI) for each outcome were based on Delphi consensus including 50 patients and 55 physicians: persistent diverticulitis (ΔNI = 4.0%), progression to complicated diverticulitis (ΔNI = 3.0%), and time to recovery (ΔNI = 5 days). Risk differences and mean differences were pooled using random-effects meta-analysis. One-sided 90% confidence intervals and Z-tests were used to determine non-inferiority. A sensitivity analysis was performed, excluding patients post hoc determined to have complicated diverticulitis. RESULTS: Nine studies (3 randomized controlled trials, 6 observational studies) met inclusion criteria: observational therapy (n = 2,011) versus antibiotics (n = 1,144). Observational therapy was noninferior to antibiotics regarding the risk of persistent diverticulitis (pooled risk differences: -0.39%, 90% CI -3.22 to 2.44%, ΔNI: 4.0%, PNI < 0.001; I2 = 66%) and progression to complicated diverticulitis (pooled risk differences: -0.030%, 90% CI -0.99 to 0.92%, ΔNI: 3.0%, PNI < 0.001; I2 = 0%). On sensitivity analysis, observational therapy remained noninferior for both outcomes. When stratified by study design, observational therapy also remained noninferior for both outcomes among randomized controlled trials only. Only 1 study reported on time to recovery as a continuous outcome, with no statistical difference between antibiotics and observational therapy. CONCLUSION: According to clinically relevant ΔNIs, observational therapy was noninferior to antibiotics for the treatment of acute uncomplicated diverticulitis with regard to persistent diverticulitis and progression to complicated diverticulitis.

BACKGROUND: Patients treated nonsurgically for complicated diverticulitis are managed by antibiotics. However, there are no recommendations concerning their duration. We aimed to determine the impact of the duration of antibiotic therapy on the risk of failure of nonsurgical treatment of complicated acute diverticulitis. PATIENTS AND METHODS: This was a single-center retrospective study of patients with computer tomography (CT)-diagnosed complicated diverticulitis between January 2015 and April 2020. Treatment failure was defined as early recurrence and/or a persistent abscess by control CT. RESULTS: In total, 148 patients fulfilled the inclusion criteria [87 men (58.8%), mean age 55±15 y]. The diverticulitis was classified as Hinchey I in 41.9%, Hinchey II in 9.5%, and pericolic free air in 48.6% of cases. The median abscess size was 2.9±1.7 cm. The median duration of antibiotic treatment was 10±4.2 days. The median follow-up was 64±60 months. The rate of failure was 12.8%. In univariate analysis, treatment >10 days (P=0.015) and an abscess >3 cm (P=0.032) were associated with a risk of treatment failure. In multivariate analysis, only the diameter of the abscess remained associated with a risk of failure (odds ratio: 1.6, 95% confidence interval: 1.09-2.4, P=0.01). CONCLUSION: This study suggests that there is no need to extend the duration of antibiotic treatment beyond 10 days in nonsurgically treated complicated acute diverticulitis.

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.

Pyoderma gangrenosum is characteristically associated with inflammatory bowel disease. However, the association between this neutrophilic dermatosis and diverticular disease is scarcely mentioned in the literature. Diverticulitis should be included in the differential diagnosis in patients with pyoderma gangrenosum and gastrointestinal complaints, or even in asymptomatic patients, particularly in the elderly. Misdiagnosis can lead to inadequate treatments and serious complications.

BACKGROUND: Despite the existing evidence, the omission of antibiotics in the management of acute uncomplicated diverticulitis has not gained widespread acceptance. OBJECTIVE: This study aims to incorporate the input of both patients and physicians on the omission of antibiotics in uncomplicated diverticulitis to generate noninferiority margins for 3 outcomes. DESIGN: This was a mixed-methods study, including in-person interviews with patients and a Delphi process with physicians. SETTINGS: North American patients and physicians participated. PATIENTS: Consecutive patients undergoing colonoscopy, 40% of whom had a previous history of diverticulitis, were selected. INTERVENTIONS: Informational video (for patients) and evidence summaries (for physicians) regarding antibiotics in diverticulitis were reviewed. MAIN OUTCOMES MEASURES: Noninferiority margins were generated for time to reach full recovery, persistent diverticulitis, and progression to complicated diverticulitis in the context of a nonantibiotic strategy. Consensus was defined as an interquartile range <2.5. RESULTS: Fifty patients participated in this study. To avoid antibiotics, patients were willing to accept up to 5.0 (3.0-7.0) days longer to reach full recovery, up to an absolute increase of 4.0% (4.0-6.0) in the risk of developing persistent diverticulitis, and up to an absolute increase of 2.0% (0-3.8) in the risk of progressing to complicated diverticulitis. A total of 55 physicians participated in the Delphi (round 1 response rate = 94.8%; round 2 response rate = 100%). Consensus noninferiority margins were generated for persistent diverticulitis (4.0%, 4.0-5.0) and progression to complicated diverticulitis (3.0%, 2.0-3.0), but could not be generated for time to reach full recovery (5.0 days, 3.5-7.0). LIMITATIONS: Patients were recruited from a single institution, and Delphi participants were invited and not randomly selected. CONCLUSION: Noninferiority margins were generated for 3 important outcomes after the treatment of acute uncomplicated diverticulitis in the context of a nonantibiotic strategy.

QUESTION: Does surgery or conservative management of recurring diverticulitis/ongoing symptoms results in a higher quality of life (QoL) at 5-year follow-up. DESIGN: Randomized controlled trial. SETTING: Multicenter trial in the Netherlands. PATIENTS: Patients aged 18 to 75 years, who presented with either ongoing abdominal complaints (for >3 months) and/or frequently recurring left-sided diverticulitis (>2 episodes in 2 years) after an objectified (via Computed Tomography, Ultrasound or Endoscopy) episode of diverticulitis were included in this study. INTERVENTION: Elective Sigmoid Resection within 6 weeks vs. Conservative Management MAIN OUTCOME:: QoL at 5-year follow-up, as measured by the Gastrointestinal Quality of Life Index (GIQLI). Secondary outcomes included additional QoL assessments (including the EuroQoL-5D-3L, Visual Analogue Score for pain, and the short form 36 health survey) RESULTS:: The intention to treat analysis showed the surgical group had a higher quality of life (GIQLI) score than the conservative group (mean difference 9.7, 95% confidence interval 1.7-17.7, P = 0.018), which approached but did not meet the minimum important difference of 10. This difference was achieved in 67% of those in the operative group versus 57% in the conservative group (many of who eventually underwent surgery). CONCLUSIONS: The study results demonstrate that HRQOL at 5-year follow-up may be improved in patients undergoing surgical resection, although this difference did not meet the MID for the GIQLI.
