Over-the-Scope Clips Show Higher Success Rates for Bariatric Surgery Leaks

A meta-analysis of five studies found that the pooled proportion of successful closure with over-the-scope clips (OTSC) for leaks and fistulae following bariatric surgery was 81.1% (95% CI 67.3 to 91.7). Observational reports suggest that patients managed with OTSC had higher rates of defect healing compared to those treated with endoscopic suturing. Larger controlled studies are recommended to further evaluate the ideal endoscopic approach for bariatric surgery complications.
