目的评价胆管内超声造影（ceIDUS）在鉴别肝分叉部胆管壁增厚中的应用价值。方法7例患者（2例原发性硬化性胆管炎[PSC]，1例继发性硬化性胆管炎[SSC]，1例原发性硬化性胆管炎[PSC]，1例继发性硬化性胆管炎[SSC]），4例肝分叉部胆管癌患者行内镜下ceIDUS检查，我们使用了利声显。结果：利声显可使PSC和SSC的胆管壁明显增强，而胆管癌的胆管壁无明显增强。结论：组织学分析有助于鉴别胆管癌和胆管炎引起的胆管壁增厚。
PurposeWe 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.
