Objective To evaluate the long-term result of jejunum-interpositioned choledochoduodenostomy with a antireflux valve after resection of choledochocele in 178 patients.Methods Postoperative patients were followed up by barium series of the upper digestive tract at different interval. To observe whether reflux remains and the severity of the reflux.Results142 out of the 178 cases (798%) were followed up, among them 21 cases (48%) without reflux, 26 cases (83%) with mild reflux, 51 cases (359%) with moderate reflux,and 28 severe cases(9%).16 cases(11.3%) had to undergo reoperation.Conclusion The technique has the effect of anti-reflux temporarily.Long-term follow-up found an increased morbidity of biliary infection, obstruction, perforation and stone formation.Severe postoperative complications necessitates a reoperation in some cases.
