摘　　要：胆道占位性病变是引起梗阻性黄疸的主要原因,但由于其位置特殊,传统的影像学诊断较为困难,超声内镜(EUS)利用消化道自然腔道,有效避开腹壁脂肪和肠道气体的干扰,使胆道系统呈现清晰的显像;尤其是近年来开展的EUS引导下的细针穿刺、造影增强超声内镜对胆道占位性病变有较高的诊断价值,在其鉴别诊断方面也发挥着越来越重要的作用。The space-occupying lesions of biliary tract is the main cause of obstructive jaundice. Because of the special location of the biliary system, traditional imaging is difficult to diagnose. Endoscopic ultrasonography(EUS) can effectively avoid the interference of abdominal fat and intestinal gas, and clearly show the biliary system. In recent years, EUS guided fine needle aspiration and contrast-enhanced endoscopic ultrasonography techniques have high diagnostic value in the space-occupying lesions of biliary tract and play an important role in the differential diagnosis of biliary tract diseases.
