[A case report of intraabdominal bleeding in unresectable pancreatic cancer after intraoperative radiotherapy].

We report a death case of 56-year-old male with unresectable pancreatic cancer. Its diagnosis was locally-advanced cancer of pancreatic head (Stage IVa) in February 2006. However, he desired no medical treatment until obstructive jaundice (T-Bil 25 mg/dL) appeared. In September 2006, endoscopic biliary metallic stenting was performed and the obstructive jaundice had improved. In November 2006, systemic chemotherapy (S-1 +gemcitabine) was performed. After the chemotherapy, vomiting had appeared because of duodenal stenosis. In December 2006, gastrojejunostomy and intraoperative radiotherapy (IORT) were performed, and the dose of oxicodon was decreased. However, in January 2007, he was suddenly in a state of bleeding-shock and died because of intraabdominal bleeding. The autopsy demonstrated the rupture of splenic pseuoaneurysm due to necrotizing pancreatitis of pancreatic tail, and cancer of pancreatic head was almost viable and IORT was not effective.
