Indication for redo hepatic portoenterostomy for insufficient bile drainage in biliary atresia: re-evaluation in the era of liver transplantation.
To determine the role of redo hepatic portoenterostomy (HPE) in biliary atresia (BA) patients with insufficient bile excretion after the initial HPE, 25 patients (type I, correctable: 2; type III, uncorrectable: 23) undergoing the initial HPE at 25 to 119 days of age were studied. Four patients achieved disappearance of jaundice (total bilirubin [T.Bil] < 2 mg/dl) postoperatively. A redo HPE was performed at 2 to 8 months of age with sufficient and extensive removal of granulation and scar tissue at the hepatic hilum. Five patients became free of jaundice in 3 to 6 months (group 1), while the remaining 20 did not (group 2). Disappearance of jaundice after the initial HPE had been achieved in 2 of 5 patients (40%) in group 1 and 2 of 20 (10%) in group 2 ( P < 0.05). Age, serum T.Bil, aspartate aminotransferase albumin, prothrombin time, cholinesterase, total cholesterol, and Fischer's ratio at redo HPE showed no significant differences between the two groups. On liver histology obtained at redo HPE, cirrhosis and hepatocyte degeneration were seen in 1 of 5 cases (20%) in group 1 and 12 of 20 (60%) in group 2 ( P < 0.05). Redo HPE may thus be effective in BA patients with insufficient bile drainage who achieved disappearance of jaundice after the initial HPE and have not developed cirrhosis.
