The technique of intraductal ultrasonography (IDUS) of the bile duct with a thin-caliber probe and a ropeway system has provided excellent images of the bile duct and periductal structures and is an easy transpapillary approach. In addition, once the guide wire is inserted into the bile duct, IDUS and transpapillary biopsy after endoscopic retrograde cholangiopancreatography can be performed in a single session. Here, we review the usefulness of IDUS in the diagnosis of cholangiocarcinoma and IgG4-related sclerosing cholangitis.
使用细口径探头和索道系统的胆管内超声检查(IDUS)技术可提供胆管及胆管周围结构的优质图像,且是一种简便的经乳头途径。此外,一旦导丝插入胆管,在内镜逆行胰胆管造影术后可在同一次操作中进行IDUS和经乳头活检。在此,我们回顾IDUS在胆管癌和IgG4相关硬化性胆管炎诊断中的应用价值。
