Abstract
PURPOSE: We carried out this study to evaluate the usefulness of contrast-enhanced intraductal ultrasonography (ceIDUS) in the differentiation of thickened bile duct wall at the hepatic bifurcation caused by malignant tumor from that caused by cholangitis. METHODS: Seven patients (two with primary sclerosing cholangitis [PSC], one with secondary sclerosing cholangitis [SSC], and four with bile duct carcinomas [BDC] at the hepatic bifurcation underwent endoscopic ceIDUS, in which we used Levovist. The recorded images of echo-brightness were analyzed histographically. RESULTS: The bile duct wall, in PSC and SSC, but not in BDC, was enhanced by Levovist. CONCLUSION: ceIDUS with histographic analysis may be useful for distinguishing thickened bile duct wall caused by malignant tumor from that caused by cholangitis.
