Abstract
BACKGROUND: Biliary atresia is a progressive biliary injury which occurs only in infants. AIMS: To review the experience of patients surviving into adulthood without the need for liver transplantation in childhood. METHODS: A multicentre review of patients with biliary atresia treated surgically who survived into adulthood without the need for transplantation. RESULTS: Twenty-two patients were identified across four centres. Median age at the last follow-up was 25 years (range: 18-46), and 21 patients had clinical features of portal hypertension. At last follow-up values of liver enzymes varied from normal to 15 x the upper limit of normal (ULN) for ALT (median 2.11 x ULN) and 9 x the ULN for ALP (median 2.02 x ULN). Six patients had a serum bilirubin > 50 mumol/l. Pruritus and jaundice were noted in 8 of 20 patients (40%) and 11 of 22 patients (50%) respectively. Thirteen patients (59.1%) were shown to have imaging features of sclerosing cholangitis, with strictures of intrahepatic bile duct(s) (IHBD), dilatation of IHBD (n = 8), or stone(s) within the IHBD (n = 5). A history of presumed bacterial cholangitis was present in 11 patients (50%). Successful pregnancies were recorded in three of fourteen female patients. Four patients underwent transplant between the ages of 20-27 years. Twenty-one patients (95.5%) were alive, including 18 (81.8%) with their native liver at the time of last follow-up. CONCLUSIONS: Some patients treated for biliary atresia will survive into adulthood with their native liver, but commonly with secondary biliary disease including cholangitis and portal hypertension.
