Introduction: Several endoscopic methods can be employed to manage post-bariatric leaks. However, endoluminal vacuum therapy (EVT) and endoscopic internal drainage (EID) are relatively new methods, and studies regarding these methods are scarce. We performed a systematic review of the literature and a meta-analysis to evaluate the efficacy of EVT and EID. Methods: Databases were searched for eligible studies. The clinical success of leak closure was the primary outcome of interest. A proportional meta-analysis was performed for pooling the primary outcome using a fixed-effects model. A meta-analysis or descriptive analysis of other outcomes was performed based on the data availability. Results: Data from 3 EVT and 10 EID studies (n = 279) were used for evidence synthesis. The leak closure rates (95% confidence interval [CI]) of EVT and EID were 85.2% (75.1%-95.4%) and 91.6% (88.1%-95.2%), respectively. The corresponding mean treatment durations (95% CI) were 28 (2.4-53.6) and 78.4 (50.1-106.7) days, respectively. However, data about other outcomes were extremely limited; thus, a pooled analysis could not be performed. Conclusions: Both EVT and EID were effective when used as the first-line treatment for post-bariatric leaks. However, larger studies must be conducted to compare the efficacy of the 2 interventions.
