Surgical treatment for type Ⅳ hilar cholangiocarcinoma / 中国普通外科杂志

ABSTRACT

Objective To explore the surgical management in patients with Bismuth Ⅳ hilar cholangiocarcinoma.Methods Retrospective study was used to analyze the clinical data with operative and pathologic diagnosis of Bismuth Ⅳ hilar cholangiocarcinoma in the recent five years.Results Of the 22 patients,there were 13 males and 9 females,with M∶F=1.4∶1.In the group of non-liver transplantation(NLTX),5 cases(31.3%) underwent resection(radical resection in 2 cases;palliative resection in 3 cases),and 11 cases had nonresectional internal or external drainage.In the liver transplantation group(LTX),the resection rate was 100 %(6/6).Five LTX cases survived for 28,19,17,12 and 9 months respectively,and one died from chronic rejection in 11 months after operation.In the NLTX group,the 1-and 2-yr survival rate was 32.1 % and 0% respectively.The 1-and 2-yr survival rate of LTX was 80.0 %(4/5)and 50.0 %(1/2)respectively.There was significant difference between the two groups in average survival rate(P=0.041).Conclusions Aggressive surgical treatment should be adopted for Bismuth Ⅳ hilar cholangiocarcinoma,and radical resection is crucial to enhance survival rate.LTX is a good choice for the patients with unresectable Bismuth Ⅳ hilar cholangiocarcinoma and the prognosis is satisfactory.
