Resection of intrahepatic bile duct carcinoma with hilar bile duct and portal vein invasion--a case report.

A case of resected intrahepatic bile duct cancer with hilar bile duct and portal vein invasion is presented. Percutaneous transhepatic biliary drainage was performed to alleviate jaundice and evaluate the biliary system. Intraductal tumor extension was determined, and an accurate histological diagnosis was made in biopsy material obtained under percutaneous transhepatic cholangioscopy. Preoperative surgical planning was carried out on the basis of an evaluation of the findings of ultrasonography, computed tomography, arteriography, portography and percutaneous transhepatic cholangioscopy. Curative surgery, which included right hepatic lobectomy with total caudate lobectomy and combined resection and reconstruction of the portal vein, was performed. Bilioenteric continuity was re-established by a Roux-en-Y jejunal loop. The histological diagnosis was moderately differentiated tubular adenocarcinoma originated in the right posterior branch of the intrahepatic bile duct. Postoperative recovery was very good, and the patient has now been enjoying a good active social life for the past three years with no signs of tumor recurrence. This case report discusses the accurate diagnosis and rational surgical treatment for intrahepatic bile duct carcinoma with hilar invasion.
