BACKGROUND/PURPOSE: The intussusception-type antireflux valve is a mechanism introduced by Nakajo, who reported the results of his initial 17 cases in 1990. This report summarizes our further experience with new @entity1 , together with follow-up results of the cases previously reported by Nakajo. METHODS: In total, 46 new @entity1 who had @entity2876 underwent portoenterostomy at the authors' two units. The authors hoped to construct the intussuscepted antireflux valve in the Roux-en-Y loop, whenever possible, at the time of hepatic portoenterostomy. RESULTS: Among the 46 @entity1 , one case each was found to be too young or too old to have the valve constructed during the surgery. In another case, the Roux-en-Y loop became too short after repeated revisions of the portoenterostomy. In another @entity1 , the valve was first constructed but later removed because of jejunal perforation near the valve. In the last @entity1 , the valve was not constructed for unspecified reasons. The authors constructed the antireflux valve in 42 @entity1 , but it was maintained in 41. In one case, the valve truly prevented reflux of the intestinal juice during an episode of @entity1321 . The valve was found to be incompetent in one @entity1 5 years after the initial surgery. CONCLUSION: The incidence of @entity255 was high in @entity1 with @entity384 of the intrahepatic bile ducts, and low in those without it.
