增强MRI及MRCP术前评估肝门胆管癌的可切除性

Preoperative evaluation of hepatic hilar cholangiocarcinoma with enhanced MRI and MR cholangiopancreatography

目的研究肝门区胆管癌的MRI表现,探讨增强MRI及MRCP对肝门区胆管癌可切除性评估价值。方法回顾性分析经手术病理证实的30例肝门区胆管癌MRI增强扫描、MRCP表现,将MRI术前可切除性评估与手术结果进行比较。结果 30例肝门区胆管癌均显示肝门区肿块,增强以延迟强化为主,肝内胆管不同程度扩张;MRI增强扫描结合MRCP可有效显示胆管受侵范围、门静脉血管受侵情况、肝实质及淋巴结有无转移。MRI综合评价肿瘤是否可切除的敏感度、特异度及准确度分别为82.4%、84.6%及83.3%。结论增强MRI结合MRCP,能在术前较为客观地对肝门区胆管癌的可切除性进行评价。

Objective：To study enhanced MRI and MR cholangiopancreatography （MRCP） findings of hepatic hilar cholangiocarcinoma and evaluate the preoperative evaluation value of MRI and MRCP. Materials and Methods：Enhanced MRI and MRCP findings in 30 patients with hepatic hilar cholangiocarcinoma proved pathologically were retrospectively analyzed,the preoperative evaluations and operative results were compared. Results：All patients were found to have soft tissue mass at porta hepatis with delayed enhancement in MRI,and intrahepatic biliary duct dilation was seen. Enhanced MRI and MRCP could find infiltrated bile duct and blood vessels objectively,metastatic tumor also could be seen availably. The sensitivity,specificity and accuracy of preoperative evaluation in all patients were 82.4%,84.6% and 83.3% respectively. Conclusion：Enhanced MRI and MRCP were valid method in the preoperative evaluation of hilar cholangiocarcinoma.
