title: Detection of large intrahepatic cholangiectases in patients with primary sclerosing cholangitis by endoscopic retrograde cholangiography.
abstract: Cholangiographic features of primary sclerosing cholangitis are multiple strictures and alternating dilated and normal segments of both intra- and extrahepatic bile ducts. Formerly, intrahepatic cholangiectases have been shown only in explanted livers, but we now describe the presence of large intrahepatic cholangiectases in a 22-year-old male patient with primary sclerosing cholangitis, visualized using a balloon catheter at endoscopic retrograde cholangiography. Cholangiectases in this patient appear to have been caused by the disease and not as a result of prestenotic dilatations. To treat possible early complications of this condition, we recommend looking for these cholangiectases when diagnostic endoscopic retrograde cholangiography is performed in primary sclerosing cholangitis.
