摘　　要：目的探讨肝外胆管疾病的超声诊断价值及漏误诊原因。方法对经内窥镜逆行胰胆管造影(ERCP)、外科手术、病理确诊的685例肝外胆管疾病进行回顾性分析,分析肝外胆管疾病超声诊断漏误诊原因。结果685例肝外胆管疾病,超声诊断诊断符合率89.34%。其中肝外胆管结石符合率88.64%(468/528),肝外胆管癌88.16%(67/76),胆道蛔虫92.59%(50/54),胆总管囊状扩张100%(27/27),漏误诊73例。结论超声对肝外胆管疾病具有较高的诊断价值。Objective To investigate the value of ultrasonic diagnosis and the reasons of missed diagnosis or misdiagnosis of extrahepatic biliary diseases. Methods We assessed 685 patients with extrahepatic biliary diseases diagnosed via ERCP, surgical operation and pathology and investigated the role of ultrasonic diagnosis and the reasons of missed diagnosis or misdiagnosis. Results In all the 685 cases, the total diagnostic coincidence rate was 89.34% in extrahepatic biliary calculi was 88.64% in cholangiocarcinoma, 88.16% in biliary tract ascariasis, 92.59%, and in choledochocele, 100%. Seventy-three cases were missed diagnosed and misdiagnosed. Conclusions Ultrasound may be worthy for diagnosis of extrahepatic biliary diseases.
