Safety and long-term outcomes of endoscopic papillary balloon dilation in children with bile duct stones

BackgroundAlthough experience with diagnostic and therapeutic ERCP in children is growing, little is known about the safety and technical outcomes of endoscopic papillary balloon dilation (EPBD) in pediatric patients with bile duct stones (BDSs).ObjectiveTo assess the safety and long-term outcomes of EPBD in pediatric patients with BDSs.DesignCase study.SettingTertiary referral center.Patients and InterventionsThis study involved 5 children who had BDSs combined with gallstones who underwent EPBD.Main Outcome MeasurementsSuccessful EPBD, successful stone removal, procedure-related complications, and long-term outcomes.ResultsERCP was successful in all cases, with cannulation and subsequent EPBD. Stone removal was performed in 1 session in all patients. No EPBD-related complications were observed in any patient. After EPBD, 1 patient subsequently underwent laparoscopic cholecystectomy for gallstones. The remaining 4 were followed without surgery. In 2 patients, gallstones were spontaneously passed from the bile duct into the duodenum. During the follow-up period, over a mean of 7.1 years (range 3.7-9.3 years), no recurrence of BDSs was observed in any patient.LimitationsSmall number of patients.ConclusionsAlthough BDSs are rare in pediatric patients, EPBD may be a safe and effective technique for the management of such stones in some children.
