Favorable internal hernia rate achieved using retrocolic, retrogastric alimentary limb in laparoscopic Roux-en-Y gastric bypass

IH is a serious complication of LRYGB that can lead to catastrophic morbidity and mortality. We advocate vigilant screening for this complication and laparoscopic exploration for patients with worrisome symptoms. Our data have indicated that a routine and consistent technique to securely close the mesenteric defects can significantly reduce the risk of IH associated with retrocolic, retrogastric placement of the alimentary limb during LRYGB.
