Controversies over the extent of surgical resection for hilar cholangiocarcinoma and research advances in diagnosis and treatment / 临床肝胆病杂志

ABSTRACT

Hilar cholangiocarcinoma (HCCA) is a common malignant tumor of the extrahepatic bile duct and has the features of special anatomical location, tumor growth along the bile duct, high degree of malignancy, and easy involvement of liver parenchyma. At present, the treatment methods for HCCA include surgical resection, non-surgical biliary drainage, neoadjuvant chemoradiotherapy, and photodynamic therapy, but surgical resection is still the preferred method. There are still controversies over the need for preoperative biliary drainage, portal vein thrombosis, and extent of surgical resection. This article elaborates on the research advances in the clinical typing of HCCA, preoperative examination and diagnosis, and treatment methods.
