Cholangiographic abnormalities in patients with inflammatory bowel disease

Abstract

Twenty patients with inflammatory bowel disease, abnormal liver function tests and abnormal endoscopic retrograde cholangiograms were found to have a spectrum of abnormalities affecting the intra- and extrahepatic biliary trees. The intrahepatic systems were abnormal in all patients and demonstrated ductal stenosis, ectasia, decreased arborization and major duct obstruction. The extrahepatic systems were abnormal in 75 percent of cases with stenosis, diverticula formation and mural irregularity being the most frequent abnormalities. The value of endoscopic retrograde cholangiography in this patient group is to exclude extrahepatic obstruction, establish a nonoperative diagnosis, and assist in determining the method of treatment.
