ObjectivesTo report the results of endoscopic dilatation of esophageal strictures in children, its complications, and their management. The outcomes of esophageal dilatation differ according to the underlying etiology.MethodsThe study included 46 patients who underwent esophageal dilatation between 2014-2019. All patients underwent a contrast study of the esophagus before endoscopic dilation to determine the location, number, and length of the narrowing. In addition, the type of dilators (balloon versus semi-rigid dilators), the number of dilatation sessions, the interval between them, and the duration of follow-up were also documented. The median age was 2.47 years, and 26 patients were females. Dysphagia was the main presenting symptom, and the leading cause of stricture was esophageal atresia.ResultsThe main treatment modality was endoscopic balloon dilatation (n=29, 63%). The esophageal diameter was significantly increased after dilation (9 [7-11] versus 12 [10-12.8]) mm; p less than 0.001). Topical mitomycin-C was used as adjuvant therapy in 3 patients (6.5%). Esophageal perforation was reported in 2 cases (4.3%). Patients needed a median of 3 dilatation sessions, 25-75th percentiles: 1-5, and the median duration between the first and last dilatation was 2.18 years 25-75th percentiles: 0.5-4.21.ConclusionEsophageal dilatation is effective for the management of children with esophageal stricture; however, repeated dilatation is frequent, especially in patients with corrosive strictures. Complications are not common, and open surgery is not frequently required.
