Abstract: Objective: To strive to standardize the radical resection of hilar cholangiocarinoma,and have better curative effects as well as better survivals. Methods: A retrospective analysis was performed in 134 patients from 1999 to 2002,of whom 48 cases had received radical resection of hilar cholangiocarcinoma. Results: Of the 134 patients,69 under resection （radical resection in 48;palliative in 21）,47 subjected to internal or external drainage and 18 only laparotomy. The total excision rate and the radical resection rate was 86.6%（116/134）and 41.2%（48/116）, the survival of the radical resection was 88.6%（39/44）. The 1,2,3-year survival rate was 75.0%、45.8%、25.0% in radical resection group,and 50%、16.7%、0 in palliative resection group respectively,there is a remarkable difference between them. Whereas in unresectional internal and external drainage group,the 1,2,3-year survival rate was 25%、 10%、 0,All the patients with only laparotomy died within one year. Conclusion: The main treatment of hilar cholangiocarinoma is operation,and radical resection plays an important role for curative effect and long term survival rate in patients with H-CC.
