Mesenteric Defect Closure Decreases the Incidence of Internal Hernias Following Laparoscopic Roux-En-Y Gastric Bypass: a Retrospective Cohort Study

摘要

Laparoscopic Roux-en-Y gastric bypass (LRYGB) is one of the most effective bariatric procedures. Internal hernia (IH) is the commonest long-term complication seen after LRYGB. We analyzed the impact of closure of mesenteric defect at primary surgery on the incidence of IH. We also studied the effectiveness of pre-operative abdominal contrast-enhanced computerized tomography (CECT) in diagnosing IH.
