梗阻性黄疸几种影像学诊断方法的评价

Evaluation of several imaging modalities in the diagnosis of obstructive jaundice

目的 评价常用的影像学检查方法对梗阻性黄疸的诊断价值。方法 回顾性分析 83例梗阻性黄疸患者的临床资料。结果 梗阻性黄疸定位和定性诊断的正确率 ,B超分别为 87.7%和5 9 .6% ;彩超为 95 .5 %和 81.8% ;CT为 94.2 %和 76.9% ,PTC为 92 .9%和 85 .7% ,ERCP为96.9%和 78.1% ,MRI/MRCP为 90 .0 %和 80 .0 %。各种诊断正确率在各种方法之间差异无显著性(P >0 .0 5 )。内镜超声仅用于 4例胆管远端梗阻的诊断 ,定位和定性诊断正确率均为 10 0 %。结论 每种影像学方法均有其优缺点 ,无一可完全替代其他方法 ,应根据患者情况选择。

Objective To evaluate the value of frequently used imaging modalities in the diagnosis of obstructive jaundice. Methods The clinical data of 83 patients with obstructive jaundice were analyzed retrospectively. Results The correct rates of localization and difinitive diagnosis were 87.7% and 59.6% by US , 95.5% and 81.8% by CDUS, 94.2% and 76.9% by CT, 92.9% and 85.7% by PTC,96.9% and 78.1% by ERCP,90.0% and 80.0% by MRI/MRCP. The differences of the correct diagnostic rates between US,CDUS,CT,PTC,ERCP and MRI/MRCP were not significant(P>0.05). EUS was only applied in 4 patients who had obstructions of the distal bile duct, the correct diagnostic rates of localization and difinitive diagnosis were both 100%. Conclusions Each imaging modality has its advantages and disadvantages, and no one can instead of the others. Proper imaging modalities should be chosen depending on patient′s conditions.
