Caustic esophageal stricture (CES) in children still occurs frequently in developing countries. We aimed to evaluate the long-term outcomes of endoscopic balloon dilatation (EBD) in treating CES in children and the influencing factors associated with outcome. We retrospectively reviewed the data of all patients who had a diagnosis of CES and underwent EBD from August 1, 2005, to December 31, 2014. The primary outcome was EBD success, which was defined as the maintenance of dysphagia-free status for at least 12 months after the last EBD. The secondary outcome was to analyze influencing factors associated with EBD success. Forty-three patients were included for analysis (29 males; mean age at first dilatation 44 months with range 121 months). 26 (60.5%) patients had long segment (>2 cm) stricture. A total of 168 EBD procedures were performed. Twenty-six (60.5%) patients were considered EBD success. Seventeen (39.5%) patients failed EBD and required stent placement and/or surgery. Patients in the EBD success group had significantly shorter stricture segments when compared to the EBD failure group ( t  = 2.398,  P  = 0.018, OR = 3.206, 95% OR: 1.228–8.371). Seven (4.4%) esophageal perforations occurred in 6 patients after EBD. Stents were placed in 5 patients, and gastric tube esophagoplasty was performed in 14 patients. In conclusion, 26 (60.5%) of 43 children with CES had EBD success. Length of stricture was the main influencing factor associated with EBD treatment outcome.
