Abstract

Abstract: Perihilar cholangiocarcinoma (phCC) is the most common type of cholangiocarcinoma, accounting for approximately 60 % of cases, followed by the distal and then the intrahepatic forms. There is not a staging system that allows comparation of all series and extract some conclusions to increase the long-survival rate in this dismal disease. The extension of the resection, which theoretically dependes on the type of phCC, is not closed subject. As surgery is the only known way to achieve a cure, many aggressive approachs have been adopted. Despite extended liver resections and even vascular resections, margins are positive in around one third of patients. In the past two decades, with advances in diagnostic and surgical techniques, the surgical outcomes and survival rates have gradually improved, although variability is the rule, with morbidity and mortality rates ranging from 14% to 76% and from 0% to 19%, respectively. Extended hepatectomies and portal vein resection even right hepatic artery reconstruction for the left side tumors are frequently needed. Salvage procedures when arterial reconstruction is not feasible, as well as hepatopancreatoduodenectomy, are still under evaluation too. In this article, we discuss the aggressive surgical approach to phCC focused on vascular resection. Disparate results on the surgical treatment of phCC made it impossible to reach clear-cut conclusions.
