    Abstract:
    OBJECTIVE: To explore the prognosis factors of hilar cholangiocarcinoma, and investigate the relation between operative procedure and prognosis of it. METHODS: A retrospective cohort study was investigated in 198 patients with hilar cholangiocarcinoma, who were treated in our hospital from December 1997 to December 2002. There were 117 males and 81 females. The age ranged from 27 to 81 years old with a mean of 56. Jaundice (94.5%), pruritus (56.6%) and abdominal pain (33.8%) were the main present symptoms. According to Bismuth-Corlette classification, there were 14 type I cases, 19 type II cases, 12 type IIIa cases, 15 type IIIb cases, 112 type IV cases and 26 unclassifiable cases. One hundred and forty four cases received open operative treatment, and the others only were treated with endoscopic approach (including ERBD or EMBE 21 cases, ENBD 31 cases) or percutaneous transhepatic cholangiodrainage (2 cases). Tumor resection was performed on 120 cases with a resection rate of 83.3%, included radical resection 59 cases (41.0%). Twenty-four cases underwent paunched biliary exploration and drainage. RESULTS: The Cox's regression model analysis showed that occupation, preoperative maximum total serum bilirubin level, operative procedure and postoperative adjuvant radiation affected postoperative survival significantly, but gender, age, choledocholithiasis, hepatitis, preoperative serum CA19-9 level, Bismuth-Corlette type, histopathologic grading and postoperative chemotherapy were not significant prognostic factors. The postoperative survival of biliary drainage group, palliative resection group and radical resection group, which statistically differed pairwise. Between ERBD or EMBE group and palliative resection group, there was no statistical difference. So was between ERBD or EMBE group and biliary drainage group, or between ENBD group and biliary drainage group. The survival differed statistically between ERBD or EMBE group and ENBD group. CONCLUSIONS: Operative procedure was the most important prognosic factor of hilar cholangiocarcinoma, radical resection still was the primary measure to cure and long term survival. For irresectable hilar cholangiocarcinoma, the effect of ERBD or EMBE could not be considered to be worse than that of open operative treatment.
