Abstract:Objective:To discuss the diagnosis and surgical treatment of hilar cholangiocarcinoma(HCC). Methods:The clinical data of 36 cases of HCC undergoing surgical treatment in the recent 5 years were analysed and summarized retrospectivly. Results:All of the patients in this group underwent operation. Postoperative complications occurred in 8 patients, included biliary fistula in 5, intra-abdominal infection in 2 and upper gastrointestinal bleeding in 1; all of the patients recovered with conservative treatment. There was no operative mortality.Of 20 patients who had received tumor resection , 15 were followed up.The median survival time was 1 year and 9 months, and the 1- and 3-year survival rate was 86.7%(13/15) and 13.3%(2/15) respectively. The shortest survival time was 11 months and the longest survuval time was 3 years and 2 month.Survival time was from 5 to 12 months and jaundice was relieved and life quality was improved in 16 and patients who received internal or external drainage. Conclusions:HCC should be resected energetically,and,whenever possible,internal or external drainage should be done in unresectable patients.
