A 39-year-old male with elevated serum transferases consulted our hospital in September 2010. Since 1999, he had worked at a printing company using organic solvents. Cholangiography revealed stenosis of the left hepatic duct with peripheral dilation, stricture of the right hepatic duct, and irregularity of the extrahepatic bile duct. As a preoperative diagnosis of sclerosing cholangitis and cholangiocarcinoma was made, extended left hepatectomy with resection of the extrahepatic bile duct and anastomosis of the anterior and posterior branches of the bile duct and the jejunum (Roux-en Y reconstruction) were performed. A histological examination showed papillary carcinoma of the medial hepatic bile duct with intraductal growth, and biliary intraepithelial neoplasia-2/3 lesions from the medial hepatic bile duct to the right hepatic and the common bile ducts. Chronic cholangitis was shown around the tumors. Postoperatively, the patient was treated with adjuvant chemo-radiation, and he is doing well 30 months after the operation, without recurrence. Unknown causes, including exposure to organic solvents, might have induced chronic bile duct injury and contributed to the development of cholangiocarcinoma.
