Abstract

An 88-year-old man, visited our hospital due to jaundice. Duodenal endoscopic findings revealed the orifice of Vater's papilla to be full of mucin. Endoscopic retrograde cholangiogra-phy (ERC) revealed a filling defect in the common bile duct and dilatation extending from the intrahepatic bile ducts to the common bile duct. Obstructive jaundice resulting from mucin-like material retention in the biliary duct was suggested. Percutaneous transhepatic cholangioscopy (PTCS) revealed tumorous lesions in the bilateral intrahepatic biliary ducts and upper common bilialy duct. The histological diagnosis of PTCS biopsy specimens was atypical epithelium which was suspicious of adenocarcinoma. The patient received microwave coagulation therapy to reduce mucus that was produced by biliary carcinoma. Obstructive jaundice had not occurred for 3 months after microwave therapy. Microwave coagulation therapy is considered to be useful for high-risk patients with mucus-producing biliary carcinoma.
