Congenital atresia of the extrahepatic biliary system has seldom been described in more than one member of a family. This note records the condition in two brothers.
Case ReportsThe unequivocal diagnosis was made in both brothers at operation and therefore details of the special investigations are not given. The results of these were, however, similar to those frequently described for sporadic cases of the same condition. between the fifth and sixth months of the pregnancy which had been otherwise normal. There was no previous foetal loss. Four generations of the family, comprising, in addition to the parents, 19 second degree relatives and 69 more distant kin, were reviewed without uncovering any significant findings.Jaundice, which rapidly deepened, was present at birth. Laparotomy at 6 weeks showed the liver to be enlarged, smooth, and tense, with thin fibrous cords representing the hepatic, the common bile, and the cystic ducts which were all completely free of bile. The gall-bladder was small and collapsed though the lumen contained some thick green bile. A diagnosis of extrahepatic biliary atresia was made and a cholecystgastroenterostomy was successfully performed.The patient was readmitted at 9 months with a respiratory infection, deep jaundice, and colourless faeces: despite antibiotic therapy he died 10 days later. Necropsy was not performed.Case 2. The second boy in the sibship, bom June 22, 1967, weighed 2876 g. at birth which followed an uneventful pregnancy and normal delivery. He was jaundiced, had colourless faeces, and his abdomen was distended by an enlarged liver. Laparotomy at 5 weeks showed a rudimentary cystic duct and a small lax gallbladder containing 2 ml. of bile-stained viscous fluid. Other parts of the portal duct system were not identified.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
