[Anatomic anomalies in neonatal cholestatic jaundice].
Disorders of the biliary tree are an important cause of cholestatic jaundice in infancy. For the most frequent diseases in this group, biliary atresia and choledochal cyst, prognosis is strongly dependent on timely diagnosis and treatment. In biliary atresia the bile flow is obstructed due to obliteration of the extrahepatic bile ducts. Construction of an hepatic portoenterostomy before 60 days of age will result in restoration of bile flow in the vast majority of patients. When failed, the disease is progressive and ultimately fatal, unless a liver transplantation is performed. For those patients in which restoration of the bile flow succeeds, the subsequent course is strongly dependent on the occurrence of cholangitis. For all patients fat-soluble vitamins should be supplemented and caloric intake should be carefully monitored. Presentation of a choledochal cyst can be either before or after the first year of life. It is mostly characterized by jaundice, with or without abdominal pain. Therapy consists of resection of the cyst, followed by a hepatico-jejunostomy. Paucity of bile ducts is an intrahepatic disorder, in which--almost--no bile ducts can be found in the portal tracts. This anomaly is frequently found in combination with a typical facies, a pulmonary stenosis and vertebral anomalies, a combination which is called Alagille syndrome. Prognosis is generally good.
