Abstract
A 67-year-old man had previously undergone distal gastrectomy reconstructed by the BillrothII method. He was referred to our hospital complaining of upper abdominal pain. Computed tomography showed emphesyma and an abscess in the retroperitoneal space aroud the pancreatic head and duodenum. Emergency surgery was performed under a diagnosis of duodenal perforation. An abscess was found in the retroperitoneal space around the pancreatic head and duodenum. Perforated duodenal diverticlum at the second portion was revealed via of an incision of the fascia. Diverticulectomy, C-tube drainage and tube duodenostomy were performed. During the postoperative course, minor leakage from the suture line occured but was managed conservatively. We report this case of perforated paraduodenal papillary diverticulum after distal gastrectomy by the BillrothIIreconstruction method.
