Background/Aims: Hilar cholangiocarcinoma (HC) is a tumor that invades the confluence of the left and right hepatic bile ducts. Surgery is the definitive treatment but is also technically demanding. Here, we report our experience on 42 patients who underwent surgical resection for HC. The aim of the present study was to evaluate the margin status of resected specimens on frozen sections and the impact of R1 resection margin on survival.
