Staple line reinforcement in laparoscopic bariatric surgery: does it actually make a difference? A systematic review and meta-analysis.

Background: Staple line leaks represent a major concern in all laparoscopic operations but are particularly important in bariatric surgery, where leak complications carry significant morbidity and mortality. Therefore, several means of staple line reinforcement have been described, but none is totally accepted. In this study, we attempt to illuminate any clear benefit of staple line reinforcement through a systematic review and meta-analysis of reported articles.
