Hilar cholangiocarcinoma (HCCA) occurs at the confluence of the right and left hepatic bile ducts. Because of the unique anatomical position and the biological behaviour of HCCA, hepatic vessels, nerves, lymph nodes and adjacent tissues are easily invaded by HCCA. The operation for HCCA is difficult, and the prognosis of patients is poor. Extended hepatectomy guided by imaging techniques shed light on the management of HCCA, while controversies on extended hepatectomy exist at home and abroad, and a standard treatment is needed to be formulated. Therefore, the surgical management for HCCA should be standardized for improving the radical resection rate, reducing the incidence of complications and mortality.
