Intraductal ultrasound (IDUS) used during endoscopic retrograde cholangiopancreatography (ERCP) can facilitate reliable evaluation of biliary and pancreatic disorders. The smaller diameter, flexibility, and the image quality offered by IDUS devices makes them ideal for evaluating a variety of difficult biliary and pancreatic diseases, especially in undefined strictures, luminal filling defects, and ampullary neoplasms. This article examines the numerous possible roles for IDUS in the evaluation of biliary and pancreatic conditions, as well as in ampullary neoplasms. IDUS is a simple, easy to learn, and safe technique that should be considered an integral tool in the therapeutic endoscopist's armamentarium.
在内镜逆行胰胆管造影（ERCP）过程中使用的导管内超声（IDUS）有助于对胆道和胰腺疾病进行可靠评估。IDUS设备较小的直径、灵活性和图像质量使其成为评估各种疑难胆道和胰腺疾病的理想选择，尤其是在不明原因的狭窄、管腔内充盈缺损和壶腹肿瘤方面。本文探讨了IDUS在评估胆道和胰腺疾病以及壶腹肿瘤方面的众多可能作用。IDUS是一种简单、易于学习且安全的技术，应被视为治疗内镜医师工具库中的重要工具。
