Abstract
We report a case of advanced duodenal cancer resected by pancreatoduodenectomy with resection of the portal vein. A 61-year-old man was admitted to our hospital complaining of appetite and weight loss. Gastrointestinal endoscopy showed a type 3 lesion in the duodenal bulb, and abdominal computed tomography (CT) and magnetic resonance imaging (MRI) showed a giant tumor of the duodenum and pancreas head that was 11 cm in size. We performed a laparotomy with a diagnosis of advanced duodenal cancer invading the pancreas and the portal vein. The tumor was adherent to the portal vein, and we resected the tumor by pancreatoduodenectomy with wedge resection of the portal vein. The tumor was histologically diagnosed as a papillary adenocarcinoma of the duodenum with portal invasion. The patient has been followed without adjuvant chemotherapy because diarrea made it unfeasible, and the lack of established chemotherapy for duodenal cancer. He has been free from recurrence as of 2 years and 2 months after the operation.
