Bowel obstruction due to internal hernia (IH) is a well-known late complication of a laparoscopic roux-en-y gastric bypass (LRYGBP). The objective of this study is to evaluate if closure of the mesenteric defect and Petersen's space will decrease the rate of internal hernias compared to only closure of the mesenteric defect. ⋯ After descriptive analysis, these results can provide strong recommendation of closure of the mesenteric defect and Petersen's space, as we notice a tendency to lower incidence of internal hernias.
