    Abstract:
    Intraoperative cholangiography revealed biliary tracts in 11 of 25 (44%) patients with biliary atresia. The outcome of these 11 patients was analyzed based on the cholangiographic patterns. In these 11 patients, 4 cases were the 1-cyst type, 3 showed a "cloudy shadow" pattern in the intrahepatic biliary tract, and 4 were subtype "a" pattern (distally patent common bile duct). Four patients showing the I-cyst type underwent hepaticojejunostomy with Rouxen-Y anastomosis, and all of the 4 became jaundice-free a few weeks after surgery. Three patients with the "cloudy shadow" pattern gained good bile drainage after hepatic portoenterostomy with Suruga II modification, all were complicated by ascending cholangitis. Three of the 4 subtype "a" pattern underwent hepatic portoenterostomy with Suruga II modification. Two became jaundice-free, while jaundice persisted in one. The subtype "a" patient who underwent hepatic porto-cholecystostomy showed poor bile drainage, and died of hepatic failure 17 months after surgery despite further surgery. From these results, we conclude that 1) hepatico-jejunostomy with Roux-en-Y anastomosis is indicated for I-cyst biliary atresia. 2) Prevention of ascending cholangitis is important in patients with the "cloudy shadow" pattern. 3) Hepatic porto-jejunostomy is indicated for the subtype "a" pattern rather than hepatic porto-cholecystostomy.
