Nonspecific ulcerated jejunitis as an unusual complication of laparoscopic cholecystectomy: report of a case.

We describe herein the case of a 65-year-old man in whom a lower gastrointestinal hemorrhage developed a few days after he underwent an elective laparoscopic cholecystectomy. A laparotomy was performed on postoperative day 16 and a jejunal segment containing mucosal changes and oozing ulcers was resected. Pathologic examination of the specimen revealed "nonspecific ulcerated jejunitis." There is no explanation for the etiopathogenesis of this pathology; however, we concluded that this clinical picture may be attributed to ischemia-reperfusion injury that occurred following an ischemic period caused by the pneumoperitoneum during laparoscopic surgery.
