ABSTRACT
Objective To explore the factors related to effects and prognosis of surgical treatment of hilar cholangiocarcinoma.Methods The clinical data of 41 patients with hilar choIangiecarcinoma(HCCA) admitted in recent seven years were investigated and anlyzed retrospectively.Results Among 41 patients with HCCA,the accuracy rate of diagnosis by imaging technology was 95.1% before operation.Thirty-two cases were treated by surgical resection,of which 15 cases had radical resection and 17 cases had palliative resection,the total resection rate was 78.1%,and 9 cases had biliary internal drinage procedure.Two cases died during hospitilization.The rate of one-,three-and five-year survival for surgical resection was 70.0%,40.0% and 23.3% respectively,and for palliation drainage was 44.4%,11.1%,and 0%,respectively.The median survial time was 28 months and 8 months for surgical resction and palliation drainage,respectively.The difference between surgical resction and palliation drainage on survival rate and median survival time was signigicant(P
