[Omental infarct after a gastric by-pass].

The authors describe the case of a 56 year old woman 25 days status post laparoscopic gastric bypass who presented with an acute onset of severe epigastric pain with signs of inflammation and localized peritoneal irritation. Although her findings suggested a late anastomotic leak, an abdominal CT scan revealed only necrosis of the greater omentum beneath the left hepatic lobe. This finding permitted a non-surgical approach; after observation over several days, the patient's symptoms resolved completely.
