Abstract

A unique case of newborn biliary atresia associated with esophageal atresia and tracheoesophageal fistula, ano-rectal atresia, Reovirus type 3 infection and an early switch of fetal into adult hemoglobin is reported. At birth, the infant, who had only one umbilical artery, was operated on by primary anastomosis of the esophagous, and descending colostomy. At six weeks of age the baby underwent a "Kasai hepatic portoenterostomy-Type I" for a EHBA Type III, Subtype C2, Subgroup O ("aplasia" of all extrahepatic biliary ducts, including the gallbladder). The absence of an artery branch for the left lobe of the liver was observed. Histologically, the liver showed a hyperplasia of the intrahepatic bile ducts due to persistence of an excess of embryologic bile ducts in "ductal plate malformation" (DPM). Specific Reovirus type 3 antibodies were found in both the mother's and baby's sera. In the postoperative period the infant developed rapid and severe liver failure and underwent a successful liver transplantation. Although in most cases EHBA appears to be a perinatal event due to a necro-inflammatory process of unknown etiology, cases associated with complex extrahepatic anomalies, may be due to different pathogenetic mechanisms supported by different causative agents operating very early in the fetal period. Viral infection seems to be the most reliable etiology.
