Evaluation of resectability of hilar cholangiocarcinoma with 64-slice CT angiography combined with negative-contrast CT cholangiography / 中国基层医药

ABSTRACT

Objective To investigate the 64-slice spiral CT angiography combined with negative contrast CT cholangiography in the evaluation of resectability of hilar cholangiocarcinoma.Methods The clinical data of 46 patients with hilar cholangiocarcinoma were analyzed.The resectability was observed by the 64-slice spiral CT angiography combined with negative contrast CT cholangiography,and compared with the postoperative results.Results Preoperative CT Bismuth-Corlette classification and postoperative results showed no significant difference (x2 =0.00,0.53,1.96,0.59,2.63,all P ＞ 0.05).Preoperative CT assessed the resectability of 26 cases with hilar cholangiocarcinoma,The intraoperation evaluated resectable 22 cases,the difference was not significant (x2 =1.51,P ＞ 0.05).Conclusion 64-slice spiral CT angiography combined with negative contrast CT cholangiography can make a good evaluation of hilar cholangiocarcinoma involving the degree of blood vessels and bile ducts,provide an important basis for the selection of clinical protocols.
