目的：探讨内镜超声检查术（EUS）对胆管下端狭窄的定性诊断价值。方法2010年1月至2012年6月，因胆管狭窄于天津市南开医院内镜诊疗中心行 EUS 检查患者83例，收集其 EUS定性诊断结果及最终确诊结果，统计 EUS 判断恶性胆管下端狭窄的准确性。结果经组织病理学确诊恶性胆管下端狭窄55例，病理阴性或无病理证据者经临床随访12～36个月证实良性胆管下端狭窄28例。EUS 定性诊断胆管下端狭窄的敏感度、特异度、阳性预测值、阴性预测值和准确率分别为98．2％（55／56）、81．5％（22／27）、91．7％（55／60）、95．6％（22／23）和92．8％（77／83）。结论EUS 判断恶性胆管下端狭窄的敏感度和准确率均较高，可用于胆管下端狭窄的定性诊断，具有较好的临床应用价值。

Objective To study the diagnostic value of endoscopic ultrasonography (EUS)for biliary stenosis.Methods Data of 83 patients with bile duct stenosis who underwent EUS from January 2010 to June 2012 at endoscopic center of Tianjin Nankai Hospital were reviewed.The EUS qualitative diagnosis and final diagnosis,and the accuracy of EUS for the lower malignant bile duct stenosis were analyzed.Results Malig-nant stenosis were confirmed histopathologically in 55 patients;benign stenosis were confirmed in 28 patients based on negative tissue sampling or extended clinical follow-up.Sensitivity,specificity,positive predictive val-ue,negative predictive value and accuracy of EUS for malignant bile duct stenosis were 98.2%(55 /56), 81.5%(22 /27),91.7%(55 /60),95.6%(22 /23)and 92.8%(77 /83),respectively.Conclusion The sensitivity and accuracy of EUS for the lower malignant bile duct stenosis is high,which is of clinical value.
