    Abstract:
    OBJECTIVE: To analyze the surgical treatment result and clinical characteristics of hilar cholangiocarcinoma in order to improve the rate of early diagnosis and radical resection. METHODS: Between 1986 and 2004,84 hilar cholangiocarcinoma patients underwent surgery, and their data were retrospectively reviewed. RESULTS: According to the Bismuth-Corlette staging system, 7 were type I, 18 type II, 22 type II a, 12 type IlI b, 20 type IV and 5 unclassified. 32 patients (38.1%) had had the history of operation for cholelithiasis before or were found to have cholelithiasis simultaneously at the time of diagnosis. The rate of making correct diagnosis by ultrasound, CT and MRCP was 71.4% , 84.0% and 91.4% , respectively. Of these 84 patients, 24 (28.6%) underwent radical resection, 14 (16.7%) palliative resection and 30 (35.7%) only internal or external drainage, while 16 patients was found to have contraindication for any further surgical intervention. The overall operation rate was 81.0% (68/84) with a radical resection rate of 35.3% (24/68). The 1-, 3- and 5-year survival rates was 70.8%, 50.0% and 20.8% in the radical resection group, and 50.0%, 21.4% and 0 in the palliative resection group, respectively. There was a statistically significant difference in the survival between two groups. Whereas in the internal or external drainage group, the 1-, 3- and 5-year survival rates was 20.0% ,10.0% and 0. All of the patients who did not undergo surgical intervention died within one year. CONCLUSION: Cholelithiasis may play an important role in the pathogenesis of hilar cholangiocarcinoma. Early diagnosis and radical resection are two important factors to improve the prognosis of hilar cholangiocarcinoma. Skeletonization of hepatoduodenal ligament with partial liver resection can improve the rate of radical resection for hilar cholangiocarcinoma.
