Extent of liver resection for hilar cholangiocarcinoma.

The article discusses a study which examines the efficacy of minor and major hepatectomy in patients with hilar cholangiocarcinoma (HC). The study shows that major liver resection must be reserved for Bismuth-Corlette type HC with vascular invasion due to its higher operative morbidity rate. It notes that patients with Bismuth-Corlette type I, II or III HC should undergo minor hepatectomy and patients with type III HC with hepatic arterial invasion should have major hepatectomy.
