BACKGROUND: Laparoscopic appendicectomy (LA) in the obese population has been controversial. A recent SAGES guideline and a Cochrane Review have suggested a benefit for LA over the open approach but did not provide supporting data. This study is the first systematic review and meta-analysis to compare the LA with open surgery in the obese population to provide a quantitative estimate of the relative benefits. METHODS: A comprehensive search of the online databases identified seven retrospective and prospective randomized studies that contained sufficient data on obese patients. Analysis was based on intention-to-treat. We calculated pooled odds ratios (ORs) and 95 % confidence intervals using a random-effects model. RESULTS: The LA group contained more females (43 vs. 32 %, p < 0.001), had fewer perforations (18 vs. 23 %; p < 0.001), and fewer overall complications (OR: 0.49; 95 % CI: 0.37-0.63), including fewer wound infections (OR: 0.34; 95 % CI: 0.18-0.66). There was no difference in the intra-abdominal abscess rate between the groups (OR: 0.99; 95 % CI: 0.29-3.37). The LA group had a shorter length of stay (2.46 vs. 3.63 days; p < 0.001) but a longer operation time (96 vs. 78 min, p < 0.001). There was no heterogeneity between the studies. CONCLUSIONS: This meta-analysis of the current published data establishes the laparoscopic approach to appendicectomy as the preferred technique for the obese population, delivering a 50 % reduction in morbidity, with a 66 % reduction in wound infections and a significantly shorter inpatient hospital stay without increasing the intra-abdominal abscess rate.
