Leaks from the gastrojejunostomy after laparoscopic Roux-en-Y gastric bypass (LRYGB) have the potential for significant morbidity and mortality. When intraoperative leaks are discovered, we choose to perform omental reinforcement around the gastrojejunostomy and pouch after suture repair of the leaks. This study examined the hypothesis that omental reinforcement would be useful after intraoperative leaks during LRYGB. Omental reinforcement was performed on gastrojejunostomies, in which leaks were seen, created using a circular stapler during LRYGB. Data were reviewed retrospectively on these patients. There were a total of 387 patients with 32 (8.26%) patients who had a staple line dehiscence or evidence of gastric pouch or gastrojejunostomy leak intraoperatively. Leaks/dehiscences were repaired with sutures and then reinforced with omentum. None of these patient developed anastomotic leak postoperatively. Of the other 365 patients, there were four (1.1%) leaks from the gastrojejunostomy and/or gastric pouch. Omental reinforcement may be useful in decreasing the incidence of postoperative leaks when an intraoperative leak is encountered during LRYGB. However, omental reinforcement does not completely prevent a postoperative leak. Consideration of reinforcement with omentum may be given for patients in whom an intraoperative leak is noted.
