[Resection for a Locally Advanced Duodenal Adenocarcinoma with Obstructive Jaundice and Hepatic and Pancreatic Invasion - A Case Report].

A 64-year-old woman diagnosed with duodenal adenocarcinoma with duodenal stenosis and obstructive jaundice was referred to our hospital. Computed tomography revealed a tumor measuring 9×6 cm in the second portion of the duodenum that had invaded the liver(S6)and head of the pancreas. After percutaneous transhepatic biliary drainage for obstructive jaundice, the patient underwent subtotal stomach-preserving pancreaticoduodenectomy, partial resection of the liver(S6), and partial resection of the colon. Histologic examination showed the primary tumor to be moderately and poorly differentiated adenocarcinoma with hepatic and pancreatic invasion; lymph node metastasis was not found. The patient received S-1 for 1 year and remains alive and well with no evidence of disease 15 months after resection.
