Gastrojejunostomy stricture rate: comparison between antecolic and retrocolic laparoscopic Roux-en-Y gastric bypass

A significant lower gastrojejunal stricture rate was observed in the retrocolic group, with no increased risk of internal hernia, when mesenteric defects were closed. The antecolic technique seems to be a risk factor for gastrojejunal stricture development after laparoscopic gastric bypass.
