Recent advance in the treatment of hilar cholangiocarcinoma: hepatectomy with vascular resection

Radical surgical resection has been revealed to be the only hope of cure for the patient with hilar cholangiocarcinoma. Therefore, major efforts have been made to increase the resection rate by surgeons employing combined hepatic resection and vascular resection of the portal vein and the hepatic artery. Especially, the technical feasibility and surgical safety of hepatic resection with combined portal vein resection have recently been reported by several authors. On the other hand, there have been few reports of combined hepatic artery resection in hilar cholangiocarcinoma. There are fears that combined vascular resection with extended hepatectomy for hilar cholangiocarcinoma may lead to high surgical morbidity and mortality. Herein, we describe the results of aggressive surgical approaches in our series, and we also review the outcomes of hepatic resection with combined vascular resection in the previously reported literature.
