Although carcinoma of hepatic hilus is generally a slow-growing tumor, the results of treatment continue to be poor, mainly, because of the low resectability rates. A case of resected carcinoma of hepatic hilus with portal vein bifurcation and proper hepatic artery invasion is presented. Preoperatively 3 seperate percutaneous transhepatic biliary drainage was made to right anterior, right posterior segment and left lobe of the liver to control cholangitis and alleviate jaundice. Curative surgery, which included extended right hepatic lobectomy with total caudate lobectomy, and combined resection of hepatoduodenal ligament and regional lymphatic tissue was performed, while an autogenous external iliac vein was interposed between root of portal vein trunk and umbilical portion of left portal vein. The use of hepatectomy with combined resection of portal vein and/or hepatic artery using vascular reconstruction allows curative surgery in the treatment of advanced carcinoma of the hepatic hilus which was previously thought to be inoperable
