Long-term safety and efficacy of closure of mesenteric defects in laparoscopic gastric bypass surgery. A randomized clinical trial.

JAMA Surg 2023; 158: 709-717.

This study included 2507 patients undergoing laparoscopic gastric bypass. Reoperation for small bowel obstruction over the next 10 years was 14.9 per cent in those having non-closure and 7.8 per cent in those with closure of the mesenteric defect: hazard rate 0.42, 95 per cent confidence interval 0.32 to 0.55.

Comment: Great study. Well powered and definitive.
