超声显像对胆总管下段梗阻病变诊断价值的探讨

目的 评估超声分辨胆总管下段梗阻病变的价值。方法 对64例胆总管下段梗阻性病变的超声诊断结果进行回顾性分析，并与手术及病理诊断作对照研究。结果 超声可清晰显示胆总管下段梗阻部位及病变特征。其定位诊断正确率为100％(64／64)，定性诊断正确率为82．81％(53／64)。结论 超声对胆总管下段梗阻的病因诊断具有重要价值，且价格低廉，无放射损伤，可作为诊断胆总管下段梗阻性病变的首选检查方法。

Discussion of diagnosis of ultrasonography in obstruction of distal common bile duct

Objective To evaluate the clinical value of ultrasonographic diagnosis for obstruction of distal common bile duct. Methods 64 cases obstruction of distal common bile duct involved in the study. They were all examined by ultrasonic, and the result compared with pathology. Results The locational accuracy rate was 100% and the qualitative accuracy rate was 82, 81 %. Conclusions Ultrasonography have important value for distal common bile duct, and would be considered as the first choice for dignostic purpose.
