PetersenÓ?s space hernia after gastric bypass

Abstract

Petersen's space hernia is the most frequent location of internal hernia after a laparoscopic gastric bypass. The diagnosis or a high suspicion of internal herniation is indications for urgent surgery. We present the case of a patient who required an exploratory laparoscopy. He had a computed tomography compatible with internal herniation. We found a Petersen's space hernia and a jejunojejunostomy defect. We reduced the protruded loops and we closed both mesenteric defects. The closure of mesenteric defects in primary surgery is a controversial matter. Overall, it is recommended to close them.
