title: Benign esophageal strictures in children and adolescents: etiology, clinical profile, and results of endoscopic dilation.
abstract: BACKGROUND
  The problem of dysphagia in children and adolescents differs from that in adults, and therefore requires special consideration.
  
  
  METHODS
  Forty-one consecutive children and adolescents 16 years of age or younger (mean, 7.2 years), with benign esophageal strictures were evaluated in a prospective manner over a 7-year period. The most frequent causes of esophageal strictures were caustic ingestion and complications of endoscopic sclerotherapy of esophageal varices. Dilation was done on a weekly basis using bougies and was considered adequate if the esophageal lumen could be dilated to 15 mm diameter (11 mm in children less than 5 years old) with complete relief of dysphagia.
  
  
  RESULTS
  Of the 30 patients who could be adequately followed after initial dilation, 16 had corrosive strictures and 14 had strictures due to other causes. Patients with corrosive strictures required a significantly higher number of sessions for adequate initial dilation (7.8 +/- 2.5 sessions vs 1.86 +/- 0.48 sessions; p < 0.01). Patients with corrosive strictures had a higher number of mean symptomatic recurrences per patient month as compared to the noncorrosive stricture group (0.15 +/- 0.01 vs 0.087 +/- 0.03, p < 0.01). Six esophageal perforations occurred during a total of 327 dilation sessions (1.8%); there was one fatality.
  
  
  CONCLUSIONS
  From our experience, we conclude that benign esophageal strictures in young patients can be treated effectively and with acceptable safety by means of endoscopic dilation.
