Perforated Ulcer of the Gastrojejunal Anastomosis and Concomitant Internal Hernia After One Anastomosis Gastric Bypass.

purposeThe management of concomitant complications after OAGB is challenging. We aim to show the surgical management of two concomitant complications after one anastomosis gastric bypass: internal hernia and anastomotic ulcer perforation. MATERIALS AND

methodsWe present the case of a 32-year-old woman with BMI of 51 kg/m2, who underwent OAGB. Three years later, she presented with intense and brutal epigastric pain. She was a heavy smoker. Her weight and BMI were 75 kg and 26 kg/m

resultsA generalized biliary peritonitis secondary to a perforated ulcer on the gastrojejunal anastomosis and internal hernia of the common loop into a large Petersen orifice were diagnosed. The internal hernia was reduced, and a perforation of the posterior surface of the gastrojejunal anastomosis was identified. Surgical treatment consisted in the placement of a Kehr's drain into the perforation, closure of the Petersen orifice, and lavage-drainage of the peritoneal cavity. The postoperative course was uneventful, and she was discharged on postoperative day 12. The Kehr's drain was removed 1 month after discharge.

conclusionThe combination of two different complications after OAGB can make the pre- and intra-operative judgment difficult and hamper the therapeutic approach. The initial reduction of the internal hernia made it possible to reduce the pressure in the surgical assembly and facilitated the treatment of the anastomotic perforation.
