肝外胆管癌的影像学诊断及评价

THE VALUE OF DIAGNOSTIC IMAGING ON THE DIAGNOSIS OF PRIMARY CHOLANGIOCARCINOMA

由于原发性胆管癌少见,早期不易确诊,常使患者失去手术机会。本文收集我院经手术、病理证实的31例胆管癌,进行影像学分析,结果是B超、PTC、CT对胆管癌的定位诊断准确率分别为71.0％、83.3％、72％。定性准确率分别为58.1％、63.1％、60％,较文献报道的低。通过误诊病例原因分析,提出了影像学综合分析对提高胆管癌确诊的重要性。

In this paper, the value of BUS, PTC and CT on the diagnosis of 31 patients with primary cholangiocarcinoma (PC), which was comfirmed by surgery and pathologic examination, was analysed retrospectively. The results showed that: (1) the accurrance rate on the location of the. disease in BUS, PTC and CT was 71. 0% , 83. 3% and 72.0% respectively. (2) the accurrance rate on diagnosis of malignancy in BUS, PTC and CT was 58.1%, 63.1 % and 60. 0 % respectively. Authors suggest that it is important to make diagnosis of PC by combine analysing the data of BUS, PTC and CT.
