Internal hernia is a known complication after gastric bypass, especially when performed laparoscopically. Potential internal locations include a transverse mesocolon defect; Petersen’s space, the area between the mesentery of the Roux limb and the transverse mesocolon; and a jejunojejunostomy mesenteric defect. Herewith is the description of our standard technique of routine closure of Petersen's space with 2/0 non-absorbable sutures.
