Abstract
Objective To evaluate the safety and efficacy of endoscopic balloon dilatation in children with anastomotic strictures after a repair of congenital esophageal atresia.Methods From June 2006 to June 2013,59 children underwent balloon dilatation for anastomotic stricture after a repair of congenital esophageal atresia.Indication for dilatation was dysphagia of varying degree.The evaluation indices included age,anastomotic size and location,number of dilatations,response to dilatation and complications.Based on dysphagia assessment 6 months after the last dilatation,the efficacy was classified as better effect,effect and no effect.Results A total of 141 dilatations were performed with an average of 2.4±1.9 sessions.The age of the first dilatation was 15.1±14.2 months.follow-up time was 6-92 months.The outcomes were better effect （n=46,78.0%）,effect （n=9,15.2%）and no effect （n=4,6.8%）.There were no procedure-related mortalities. Conclusions Endoscopic balloon dilatation may be accomplished safely and effectively as a first-line therapy for anastomotic strictures after a repair of congenital esophageal atresia.
