J Infect Chemother 2024; 30:118-122. [PMID: 37739180 DOI: 10.1016/j.jiac.2023.09.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Revised: 09/13/2023] [Accepted: 09/18/2023] [Indexed: 09/24/2023]
Abstract
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.

Korean J Intern Med 2023; 38:672-682. [PMID: 37586812 PMCID: PMC10493441 DOI: 10.3904/kjim.2023.133] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/19/2023] [Revised: 05/09/2023] [Accepted: 05/30/2023] [Indexed: 08/18/2023] Open
Abstract
BACKGROUND/AIMS Some management strategies for acute colonic diverticulitis remain controversial in Korean real-world practice because their clinical features differ from those in the West. This study aimed to investigate the opinions of Korean physicians regarding the diagnosis and treatment of acute diverticulitis. METHODS A web-based survey was conducted among gastroenterologists specializing on treating lower gastrointestinal disorders. The questionnaires concerned overall management strategies for colonic diverticulitis, including diagnosis, treatment, and follow-up. RESULTS In total, 209 gastroenterologists responded to the survey. Less than one-fourth of the respondents (23.6%) answered that left-sided colonic diverticulitis is more likely to be complicated than right-sided colonic diverticulitis. Most respondents agreed that immunocompromised patients with diverticulitis have worse clinical outcomes than immunocompetent patients (71.3%). Computed tomography was the most preferred tool for diagnosing diverticulitis (93.9%). Approximately 89% of the respondents answered that they believed antibiotic treatment is necessary to treat acute uncomplicated diverticulitis. Most respondents (92.6%) agreed that emergency surgery is not required for diverticulitis with an abscess or microperforation without panperitonitis. Further, 94.7% of the respondents agreed that colon cancer screening is necessary in patients aged ≥ 50 years with diverticulitis after they have recovered from acute illness. Many respondents (71.4%) agreed that surgery for recurrent diverticulitis should be individualized. CONCLUSION Opinions regarding management strategies for colonic diverticulitis among Korean gastroenterologists were well agreed upon in some areas but did not agree well in other areas. Evidence-based guidelines that meet the practical needs of the Korean population should be developed.

Abstract
PURPOSE In the West, diverticular disease is located mainly in the left colon. However, it can also present in the right colon, with an incidence of 1% to 2% in Caucasians. The purpose of this study was to describe our experience in right-sided acute diverticulitis (RD). METHODS In this retrospective study, 410 patients with acute diverticulitis treated from 2013 to 2020 were included in a university hospital in Córdoba, Argentina. Colonic diverticulitis was stratified into 2 groups; RD and left-sided acute diverticulitis. Demographic and clinical variables, laboratory and imaging findings, type of treatment, follow-up, and recurrence were analyzed. RESULTS Sixteen patients (3.9%) with RD were identified; 62.5% were male and the mean age was 40.7±11.7 years. A total of 81.3% were Caucasian and 18.7% Native American. Significant differences were found between both groups of diverticulitis; patients with RD were younger (P=0.001), with lower BMI (P=0.01), comorbidity rate (P=0.01), Charlson comorbidity index (P=0.02), hospital stay (P=0.01), severity according to the Hinchey classification (P=0.001) and had a lower recurrence rate (P=0.001). There were no significant differences in sex (P=0.95), duration of pain until admission (P=0.05), laboratory findings (P=0.23) and treatment (P=0.34). CONCLUSION Conservative treatment predominated in RD, with a lower rate of complications and recurrences, providing data that support conservative therapy as initial treatment in RD in our environment.

Abstract
Non-operative treatment is the mainstay of colonic diverticulitis, but some patients require surgery due to non-operative treatment failure. This study aims to identify risk factors for the failure of non-operative treatment of colonic diverticulitis. From January 2011 to December 2020, we retrospectively reviewed 2362 patients with non-operative treatment for first-attack acute diverticulitis. Patients were categorized into non-operative treatment success or failure groups. Clinical characteristics and serum inflammatory markers were analyzed by multivariable logistic regression to determine risk factors for non-operative treatment failure of colonic diverticulitis. Overall, 2.2% (n = 50) of patients underwent delayed surgery within 30 days (median 4.0 [3.0; 8.0]) due to non-operative treatment failure. Multivariable logistic regression identified that platelet to lymphocyte ratio (odds ratio [OR], 4.2; 95% confidence interval [CI], 0.05-0.13; p < 0.001), diabetes mellitus (OR, 2.2; 95% CI, 0.01-0.09; p = 0.025), left-sided colonic diverticulitis (OR, 4.1; 95% CI, 0.04-0.13; p < 0.001), and modified Hinchey classification (OR, 6.2; 95% CI, 0.09-0.17; p < 0.001) were risk factors for non-operative treatment failure. Platelet to lymphocyte ratio (PLR) is a potential risk factor for the non-operative treatment failure of acute first-attack colonic diverticulitis. Therefore, patients with higher PLR during non-operative treatment should be monitored with special caution.

Abstract
Background There is no sufficient overview of outcomes in right-sided and left-sided colonic diverticulitis (CD) following non-operative management. This systematic review was conducted to evaluate the recurrence/treatment failure in right-sided and left-sided CD. Methods A systematic review was conducted following PRISMA guidelines. MEDLINE, Embase, and Cochrane Library from inception to Dec 2021 were searched. The study characteristics, recurrence/treatment failure, and risk factors for recurrence/treatment failure were extracted. Proportional meta-analyses were performed to calculate the pooled recurrent/treatment failure rate of right-sided and left-sided CD using the random effect model. Logistic regression was applied for the factors associated with the recurrence/treatment failure. Results Thirty-eight studies with 10,129 patients were included, and only two studies comprised both sides of CD. None of the studies had a high risk of bias although significant heterogeneity existed. The pooled recurrence rate was 10% (95% CI 8–13%, I2 = 86%, p < 0.01) in right-sided and 20% (95% CI 16–24%, I2 = 92%, p < 0.01) in left-sided CD. For the uncomplicated CD, the pooled recurrence rate was 9% (95% CI 6–13%, I2 = 77%, p < 0.01) in right-sided and 15% (95% CI 8–27%, I2 = 97%, p < 0.01) in the left-sided. Age and gender were not associated with the recurrence of both sides. The treatment failure rate was 5% (95% CI 2–10%, I2 = 84%, p < 0.01) in right-sided and 4% (95% CI 2–7%, I2 = 80%, p < 0.01) in left-sided CD. The risk factors for recurrence and treatment failure were limited. Conclusion Non-operative management is effective with low rates of recurrence and treatment failure for both right-sided and left-sided CD although left-sided exhibits a higher recurrence. The recurrence rates did not differ between patients receiving antibiotics or not in uncomplicated CD. Age and sex were not associated with the recurrence although other risk factors were dispersing. Further risk factors for recurrence and treatment failure would be investigated for precise clinical decision-making and individualized strategy.

Investigation of the clinical features and recurrence patterns of acute right-sided colonic diverticulitis: A retrospective cohort study. Ann Med Surg (Lond) 2022; 81:104431. [PMID: 36147058 PMCID: PMC9486599 DOI: 10.1016/j.amsu.2022.104431] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Revised: 08/06/2022] [Accepted: 08/12/2022] [Indexed: 11/26/2022] Open
Abstract
Background Right-sided colonic diverticulitis (RCD) and left-sided colonic diverticulitis (LCD) are considered distinct diseases. However, separate guidelines for RCD do not exist. Since the establishment of RCD management would first require evaluation of disease characteristics and recurrence patterns, this study has aimed to investigate the differences in the clinical characteristics between RCD and LCD and the recurrence patterns of RCD. Methods Patients admitted for colonic diverticulitis between January 2012 and August 2020 were retrospectively reviewed. Clinical characteristics and recurrence rates in RCD and LCD patients, and predictors for recurrence and the recurrence patterns of RCD were analyzed. Results In total, 446 colonic diverticulitis patients (343 RCD, 103 LCD) were included in this study. RCD patients were more likely to be male, younger, taller, heavier, smoke, drink alcohol, have better physical performance scores, lower modified Hinchey stages and better initial laboratory findings. LCD patients were more likely to receive invasive treatments, have longer fasting and hospital days, higher mortality and cumulative recurrence rates (20.5% vs. 30.4%, P = 0.007). Recurrences in most RCD patients were of similar disease severity and received the same treatments for initial attacks, with rates of recurrence increasing after each recurrence. Predictors of the recurrence of RCD were complicated diverticulitis (hazard ratio[HR] 2.512, 95% confidence interval[CI] 0.127–5.599, p = 0.024) and percutaneous drainage (HR 6.549, 95% CI 1.535–27.930, p = 0.011). Conclusion RCD is less severe and has a lower recurrence rate than LCD, suggesting that RCD should be treated conservatively. Patients with complicated diseases and those requiring percutaneous drainage are more likely to experience a disease recurrence, suggesting nonsurgical management may be insufficient. Right-sided colonic diverticulitis patients were more likely to be male, younger, taller, heavier, smoke and drink alcohol. Right-sided colonic diverticulitis is less severe and has a lower recurrence rate than left-sided colonic diverticulitis. Patients with complicated disease and those requiring percutaneous drainage are more likely to experience disease recurrence.

Abstract
PURPOSE Right-sided diverticulitis has different epidemiologic features compared to left-sided diverticulitis. However, data on the appropriate treatment of right-sided diverticulitis are lacking. This systematic review aimed to examine the outcomes of conservative treatment for uncomplicated right-sided diverticulitis. METHODS MEDLINE, Embase, and the Cochrane Library were searched for articles published from January 1, 1990, to May 31, 2020. A total of 21 studies were included in the systematic review. We calculated proportions and 95% confidence intervals (CIs) to assess the outcomes of individual studies and pooled the results using a random effects model. RESULTS A total of 2811 patients (59.1% men; mean and median age, 37-54 years) with right-sided diverticulitis were included. The pooled rate of treatment failure was 2.5% (95% CI 1.2-4.3%; p <0.01; I2 = 64.0%). The recurrence rate ranged from 0 to 26.9%, and the pooled recurrence rate was 10.9% (95% CI 8.1-14.1%; p <0.01; I2 = 78.2%). The pooled rate of complicated diverticulitis at recurrence was 4.4% (95% CI 1.4-9.0%; p = 0.84; I2 = 0%). The pooled rate of emergency surgery at recurrence was 9.0% (95% CI 4.6-14.7%; p = 0.12; I2 = 30.3%). CONCLUSIONS Conservative treatment of uncomplicated right-sided diverticulitis results in a low rate of recurrence and complicated diverticulitis at recurrence. Based on these results, unnecessary surgery may be avoided and a new treatment paradigm for uncomplicated right-sided diverticulitis may be introduced.

Abstract
BACKGROUND Once considered to be a congenital condition, the epidemiology of right-sided colonic diverticulosis (RCD) is evolving. Acute diverticulitis (AD) is a complication of RCD which is frequently misdiagnosed as appendicitis, resulting in unnecessary surgery, as there is strong evidence supporting medical management for right-sided AD. In general, the incidence of AD correlates with the prevalence of RCD, which shows marked geographic variation. Few data reporting RCD prevalence come from Western countries, so the aim of this study is to define the prevalence of RCD in a New Zealand population. METHODS Independent review of the imaging from 1000 consecutive patients undergoing a computed tomography Kidney/Ureter/Bladder scan for suspected urolithiasis at Christchurch Hospital between January and November 2017 was undertaken, to determine the presence or absence, and distribution of colonic diverticulosis. Patients were excluded if they had a history of colonic resection, known IBD, or were less than 18-years old. RESULTS Thirty-one patients were excluded, leaving 969 eligible patients. Overall, 95 patients (9.8%) had RCD identified. The prevalence of RCD increased significantly with advancing age, being present in 2.3% of those aged 18-29, increasing to 20.3% in those greater than 70-years old (p < 0.001). CONCLUSION The prevalence of RCD in a New Zealand population is relatively high and increases significantly with age. This adds support to the role of cross-sectional imaging in the evaluation of suspected appendicitis, to exclude right-sided AD. The association with advancing age supports RCD being an acquired condition rather than a congenital condition as was previously thought.

Abstract
AIM The aim of this work was to compare demographic factors, outcomes and prognosis for right-sided versus left-sided acute colonic diverticulitis. METHOD We searched MEDLINE, CINAHL, EMBASE, CENTRAL, Scopus and unpublished literature to identify all observational studies comparing demographic factors and outcomes of right-sided versus left-sided acute colonic diverticulitis (PROSPERO registration number CRD42020180075). We used the QUIPS tool to assess the risk of bias of included studies. Random effects modelling was applied to calculate pooled outcome data. RESULTS Analysis of 2933 patients from nine studies suggests that right-sided diverticulitis affects younger patients [mean difference (MD) -14.16 (-17.19, -11.14), P < 0.00001] and more male patients [odds ratio (OR) 1.33 (1.04, 1.71), P = 0.02] compared with left-sided diverticulitis. Smoking [OR 2.23 (1.50, 3.32), P < 0.0001], alcohol consumption [OR 1.85 (1.26, 2.71), P = 0.002] and comorbidity [OR 0.21 (0.15, 0.30), P < 0.00001] were more common in patients with right-sided diverticulitis. The risk of complicated diverticulitis was lower in the right-sided group [OR 0.21 (0.08, 0.55), P = 0.001]. More patients in the right-sided diverticulitis group had modified Hinchey Stage I disease [OR 10.21 (3.34, 31.22), P < 0.0001] while more patients in the left-sided group had Stage II [OR 0.19 (0.10, 0.38), P < 0.00001], Stage III [OR 0.08 (0.01, 0.54), P = 0.009] or Stage IV disease [OR 0.02 (0.00, 0.08), P < 0.00001]. Right-sided diverticulitis was associated with a lower risk of recurrence [OR 0.49 (0.25, 0.98), P = 0.04], failure of conservative management [OR 0.14 (0.04, 0.43), P = 0.0006], the need for emergency surgery [OR 0.13 (0.05, 0.36), P < 0.00001] and a shorter length of hospital stay [MD -1.70 (-3.08, -0.33), P = 0.02]. CONCLUSION Right-sided acute diverticulitis predominantly affects younger male patients compared with left-sided disease and is associated with favourable outcomes as indicated by the lower risk of complications, failure of conservative management, need for emergency surgery, recurrence and shorter length of hospital stay. More studies are required to compare the postoperative outcomes in patients with right-sided and left-sided diverticulitis undergoing emergency surgery.

[PMID: 32111862 PMCID: PMC7048749 DOI: 10.1038/s41598-020-60397-5] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2019] [Accepted: 02/12/2020] [Indexed: 12/11/2022] Open
Abstract
Right colonic diverticulitis (RCD) and left colonic diverticulitis (LCD) may have different clinical features due to the different embryologic origins and anatomical locations of each colon. Therefore, we aimed to compare RCD and LCD in terms of the associated clinical features. We retrospectively collected clinical data from patients who were diagnosed with acute colonic diverticulitis based on computed tomography findings between 2011 and 2017. RCD was defined as colonic diverticulitis extending from the caecum to the transverse colon, and LCD was defined as extending from the splenic flexure to the sigmoid colon. These analyses included 667 patients with RCD and 58 patients with LCD. Relative to the patients with LCD, the patients with RCD were younger (P < 0.001), were more likely to be male (P = 0.033), were taller (P < 0.001), had lower body mass index values (P < 0.001), had less advanced modified Hinchey stages (P < 0.001), and had shorter hospital stays (P < 0.001). Having LCD rather than RCD was a predictor of recurrent colonic diverticulitis (P = 0.003). Relative to LCD, RCD occurs at younger ages, is expressed at less advanced modified Hinchey stages, and is associated with lower risks of recurrence.

Prospective randomized clinical trial of uncomplicated right-sided colonic diverticulitis: antibiotics versus no antibiotics. Int J Colorectal Dis 2019; 34:1413-1420. [PMID: 31267222 DOI: 10.1007/s00384-019-03343-w] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 06/26/2019] [Indexed: 02/04/2023]
Abstract
PURPOSE Antibiotics are widely used in the treatment of uncomplicated left-sided colonic diverticulitis. In Asian countries, however, right-sided colonic diverticulitis is more common than left-sided colonic diverticulitis. The aim of the present study was to evaluate the need for antibiotics in the treatment of uncomplicated right-sided colonic diverticulitis in an Asian population. METHODS Patients were randomized to two management strategies: antibiotics and no antibiotics. At 4-6 weeks after discharge, the patients in both groups underwent computed tomography or were contacted by phone to confirm the effectiveness of the treatment. The primary end point was the treatment failure rate of the initial treatment, and secondary end points were the length of hospital stay and total admission costs. RESULTS Patients were randomized to treatment with (61 patients) or without (64 patients) antibiotics. The rates of treatment failure in the antibiotics and no antibiotics groups were 1.7% and 4.6%, respectively, with no significant difference (P = 0.619). There was also no significant difference in the length of hospital stay between the groups (P = 0.983). Total admission costs were lower in the no antibiotics group than in the antibiotics group (US$1004.70 vs US$1112.40, respectively, P = 0.037). CONCLUSION Conservative management of uncomplicated right-sided colonic diverticulitis without antibiotics shows similar treatment failure rates and length of hospital stay, and is associated with lower hospital costs, compared with standard antibiotic treatment. Therefore, conservative management can be considered as a safe treatment option. TRIAL REGISTRATION ClinicalTrial.gov No. NCT02314013.

Effects of Burdock tea on recurrence of colonic diverticulitis and diverticular bleeding: An open-labelled randomized clinical trial. Sci Rep 2019; 9:6793. [PMID: 31043657 PMCID: PMC6494891 DOI: 10.1038/s41598-019-43236-0] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2018] [Accepted: 04/17/2019] [Indexed: 01/22/2023] Open
Abstract
Colonic diverticular bleeding (CDB) and acute colonic diverticulitis (ACD) show high recurrence rates. The establishment of optimal strategies that prevent the recurrence of CDB and ACD is a major concern among gastroenterologists. This study aimed to assess the efficacy of burdock tea for preventing CDB and ACD recurrences. Newly diagnosed patients with CDB (n = 91) or ACD (n = 70) were randomly assigned into two groups. The experimental group received 1.5 g of burdock tea three times a day, whereas the control group did not receive any treatment. The median (interquartile range) of observation for recurrence of CDB or ACD was 22.0 (14.1) months and 30.3 (18.6), respectively. The burdock tea treatment showed significant preventive effects on recurrence of ACD. A lower ACD recurrence rate (5/47 [10.6%] vs. 14/44 [31.8%]) and longer recurrence-free duration was observed in the burdock tea group (59.3 months [95% CI: 54.0–64.7] vs. 45.1 months [95% CI: 37.1–53.0] by the Kaplan-Meier analysis; p = 0.012 by log rank test) than in the control group, although there was no significant preventive effects on the CDB recurrence. This randomized clinical trial demonstrated that daily intake of burdock tea could be an effective strategy for prevention of ACD recurrence, but not for CDB recurrence.
