Abstract
Of 88 cases of extrahepatic biliary atresia, satisfactory bile flow has been established in 46% of the patients who have undergone portoenterostomies and in 25% of patients with hepaticojejunostomies. Histological analysis of the extrahepatic biliary tissue has not shown a consistent correlation with outcome of operation, except that the patients with one or two large residual ducts lined with columnar epithelium have a better chance of developing bile flow. Cholangitis developed in 43% of the cases, and co-trimoxazole was not shown to have any beneficial effect in a small prospective trial in 18 patients. Severe haemorrhage from oesophageal varices has occurred in 4 jaundice-free survivors. Seventeen patients are now over 3 years of age and thriving but many show persistent elevation of liver enzymes.
