AbstractThe current treatment for acute appendicitis is an appendectomy. Several studies have, however, assessed the efficacy of an antibiotic for treating acute appendicitis that is either uncomplicated or complicated by local peritonitis. A meta-analysis in 2007 that collected the results of 44 prospective studies showed that antibiotics were efficacious in 92.8% of cases of appendicitis complicated by local peritonitis, with percutaneous drainage of an abscess when necessary. No predictive factor for failure was identified. The failure of antibiotic treatment did not increase morbidity. Over time and on the whole, the recurrence rate was only 8.9%. The risk of cancer of the appendix (1.5%) nonetheless led to the recommendation of an interval appendectomy for adults. Four randomized controlled trials have compared antibiotic treatment with an appendectomy for the treatment of uncomplicated acute appendicitis. The efficacy of the antibiotic treatment ranged from 86 to 100% and the recurrence rate from 10.4 to 35%. These studies have had various methodological impediments; however, too few patients were included (40 and 80 patients), or only a clinical diagnosis was made before inclusion, or important protocol violations occurred, in particular for almost half the patient in the antibiotic therapy group in the 2009 study. These problems prevent us from relying on these authors' findings. Antibiotics have a role in the initial treatment of acute appendicitis complicated by local peritonitis. In uncomplicated acute appendicitis, the methodological inadequacy of the currently available randomized trials makes it impossible to reach a definitive conclusion about the efficacy of antibiotics.
