Antecolic versus retrocolic alimentary limb in laparoscopic Roux-en-Y gastric bypass: a comparative study

A greater incidence of intestinal obstruction and internal hernia was observed in the retrocolic technique group than in the antecolic technique group undergoing LRYGB. The results of our study have shown that the use of the retrocolic technique is a risk factor for intestinal obstruction after LRYGB.
