Extended right hepatic lobectomy with resection of inferior vena cava and portal vein for intrahepatic cholangiocarcinoma

We report a case of intrahepatic cholangiocarcinoma treated by extended right lobectomy and resection of the inferior vena cava (IVC) and portal vein. A 53-year-old man was referred with elevated serum alkaline phosphatase (ALP) and γ-glutamyl transpeptidase (γ-GTP) levels on April 23, 1999. He was not jaundiced and did not have any symptoms. Endoscopic retrograde cholangiopancreatography (ERCP) revealed irregular strictures in both the anterior and posterior segmental ducts. Contrast-enhanced computed tomography (CT) scan demonstrated a low-density tumor with an unclear margin in the right lobe of the liver. The patient underwent extended right hepatic lobectomy and total caudate lobectomy. Partial resection of the IVC (6 cm) was performed under total hepatic vascular exclusion. The main portal trunk and left portal vein were resected and reconstructed with an end-to-end anastomosis. Macroscopically, a 5.0 × 5.0 × 4.5-cm periductal infiltrating-type tumor occupied the right hepatic parenchyma along the posterior and anterior segmental ducts. Histological examination revealed moderately differentiated tubular adenocarcinoma with marked perineural invasion. Lymph node metastasis was observed in the hepatoduodenal ligament and posterior surface of the pancreatic head. The resected margins of the common bile duct and left hepatic duct were free of tumor. The patient's postoperative course was uneventful, and he was discharged from hospital on the 28th postoperative day. Nine months after the operation, he suddenly developed obstructive jaundice, and died with recurrent disease. This is the first reported case of intrahepatic cholangiocarcinoma treated with major hepatectomy and resection of the IVC and portal vein except ex situ procedure. This aggressive surgical approach may offer hope for patients with intrahepatic cholangiocarcinoma involving the IVC. Received: March 27, 2000 / Accepted: August 8, 2000
