Abstract
A 76-year-old female patient was referred to our hospital with diagnosis of suspicious acute cholecystitis. CT study revealed retroperitoneal emphysema and possible duodenal perforation or retroperitoneal abscess was suspected and an emergent operation was performed. A necrotic cystic mass of 2cm in diameter was found in the descending part of the duodenum and the wall of the cystic mass was incised and a drainage was performed. Possible perforation of the duodenal diverticulum was considered but the definite diagnosis was not established without proof in the intraopretive image findings. Postoperative image study through the drain visualized duodenum and the presence of a duodenal diverticulum. We report a case of perforation of paraduodenalpapillary diverticulum managed with a drainage.
