[Surgical treatment of patients with hilar cholangiocarcinoma in a single center].

Objective: To study the experience of preoperative evaluation, surgical planning and postoperative treatment of hilar cholangiocarcinoma (HCC) in our center. Method: The clinical data of 70 patients with HCC who underwent resection at the First Affiliated Hospital of Bengbu Medical College, from January 2011 to December 2017 were analyzed retrospectively. The treatment experience of HCC from the aspects of preoperative evaluation and treatment, surgical methods, postoperative recovery and prognosis were discussed. Results: The accurate evaluation of HCC by three-dimensional visualization technology was beneficial to the formulation of surgical plan preoperatively. Extended hemihepatectomy or combined resection of caudate lobe or portal vein was effective for type Ⅲ-Ⅳ HCC. The R0 resection rate was 93% (53/57). Postoperative pathology showed that high/middle/low differentiated adenocarcinoma of 21/30/16, adenoma in 2 cases, inflammatory lesion in 1 case. The 1/3/5-year overall survival rates of patients with adenocarcinoma after chemotherapy were 87%(60/69)/47.0%(31/66)/30.2%(19/63) respectively. Conclusion: HCC patients who under radical surgery after preoperative evaluation and postoperative chemotherapy can obtain a good prognosis. Expanding hepatectomy can improve R0 resection rate and prognosis in patients with type Ⅲ-Ⅳ HCC.
