{Abstract}: Omental infarction is a rare phenomenon that can be idiopathic or secondary to a surgical intervention. Greater omentum division has been advocated to decrease tension at the gastro-jejunal anastomosis during laparoscopic Roux-en-Y gastric bypass (RYGB). We report a case of omental infraction complicated by liquefied infected necrosis presenting 3 weeks after antecolic antegastric RYGB. The patient underwent laparotomy and subtotal omentectomy with a protracted hospital course due to intra-abdominal abscesses, acute kidney injury and small bowel obstruction that were successfully managed non-operatively. We reviewed the available literature on omental infarction after RYGB, focusing on associated symptoms, possible etiology, timing of presentation, management and propose an alternative technique without omental division.
