Abstract

Aims 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 versus antibiotics in AUD patients. Methods This review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses to identify randomised controlled trials (RCTs) involving AUD patients which compared the use of antibiotics with no antibiotics. Pooled outcome data was calculated using random effects modelling with 95% confidence intervals (CI). Results Five 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: 0.61, 95% CI :0.27-1.36, p=0.23), abscess (OR: 0.51, 95% CI: 0.08-3.25, p=0.47) or fistula (OR: 0.33, 95% CI: 0.03-3.15, p=0.33) formation, perforation (OR: 0.98, 95% CI: 0.32-3.07, p=0.98), recurrence (OR: 0.96, 95% CI: 0.66-1.41, p=0.85) need for surgery (OR: 1.36, 95% CI: 0.47-3.95, p=0.37), mortality (OR: 1.27, 95% CI: 0.14-11.76, p=0.82) or length of stay (MD: 0.215, 95% CI: -0.43-0.73, p=0.61) between the two groups. However, the likelihood of readmission was higher in the antibiotics group (OR: 2.13, 95% CI: 1.43-3.18, p=0.0002). 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.
