Role of CT and MRI on preoperative evaluation of hepatic hilum cholangiocarcinoma
Objective To explore the value of CT and MRI on preoperative evaluation of hepatic hilum cholangiocarcinoma. Methods CT/MRI and CTA, MRCP findings in 23 patients of hepatic hilum cholangiocarcinoma proved pathologically were retrospectively analyzed. Imaging classification and clinical classification were compared, as well preoperative evaluations and operative results were compared. Results All patients were found to have soft tissue mass at porta hepatis with delayed enhancement, and intrahepatic biliary duct dilation was seen. CT/MRI and CTA, MRCP imaging could find infiltrated bile duct and blood vessel objectively, metastatic tumor also could be seen availably. The classification was of no significant difference between CT/MRI and operation findings（P＞0.05）. The sensitivity and specificity and accuracy of preoperative evaluation in all patients of hepatic hilum cholangiocarcinoma were 81.8％ and 91.6％ and 86.9％ in our study. Conclusions CT combined with MRI was valid method in the anatomical analysis of hilar cholangiocarcinoma, and they were helpful in clinical classification and preoperative evaluation.
