目的探讨影像学诊断肝门部胆管癌的价值及术前评估肿瘤切除的准确性。方法对71例经病理或临床证实的肝门部胆管癌病人,进行影像学检查资料总结。结果肝门部胆管癌:B超、CT、PTC、ERCP、MRCP 术前临床诊断准确率分别为:81.7,87.3,96.4,96.3,100％,实际切除与术前评估能够切除数比率分别为:40.4,36.2,78.3,71.4,93.3％。结论肝门部胆管癌在定性诊断上 MRCP、PTC 和 ERCP 虽高于 B 超及 CT,但无统计学意义(P>0.05);在评估切除准确率上MRCP、ERCP 和 PTC 明显高于 B 超和 CT(P<0.05)。
Objective To investigate the value of imaging diagnosis of hilar cholangiocarcinoma and the accuracy of preoperative evaluation of tumor resection. Methods Totally 71 cases of pathologically or clinically confirmed cases of hilar cholangiocarcinoma were studied by imaging examination. Results The accuracy of preoperative diagnosis of hilar cholangiocarcinoma was 81.7%, 87.3%, 96.4%, 96.3%, 100% respectively. The rates of resection and preoperative evaluation of resectability were as follows: 40.4, 36.2, 78.3, 71.4, 93.3%. Conclusions The diagnostic accuracy of MRCP, PTC and ERCP in hilar cholangiocarcinoma is higher than that of B-ultrasound and CT, but there is no statistical significance (P> 0.05). MRCP, ERCP and PTC in evaluating hilar cholangiocarcinoma are significantly higher than those in B- And CT (P <0.05).
