Biliary tract obstruction in the acquired immunodeficiency syndrome.
Three patients with the acquired immunodeficiency syndrome had biliary obstruction resulting from benign strictures of the biliary tract. Stenosis of the distal common bile duct with differing degrees of irregularity of the smaller intrahepatic and extrahepatic ducts was seen in association with either cryptosporidial or cytomegaloviral infection of the biliary tree. We review cytomegaloviral and cryptosporidial infections of the biliary system, as well as possible relationships with idiopathic primary sclerosing cholangitis. Stenotic biliary tract disease appears to be yet another complication of the acquired immunodeficiency syndrome.
