A 10-month old boy transplanted with a left lateral segment for extrahepatic biliary atresia developed progressive increases of serum -glutamyltransferase and intrahepatic biliary tree distension three months after transplant. Transhepatic cholangiography was performed and a biliary stent was placed (1). Eighteen days later the cholangiography showed a patent hepaticojejunostomy, with an intestinal stricture a few centimeters below the bilioenterostomy, where an intestinal valve had been created at the time of Kasai portoenterostomy (2). The child underwent laparotomy with resection of the intestinal loop and revision of the hepaticojejunostomy. Four months after surgical revision, liver chemistries showed persistence of cholestasis. Percutaneous transhepatic cholagiography was performed with evidence of intrahepatic biliary ducts distension (3), balloon dilation was performed (4) and a stent was left in place (5). The control cholangiography performed 46 days later demonstrated a patent hepaticojejunostomy and the stent was removed (6).
