Endoscopic dilatation of esophageal strictures in children and adolescents

To assess the causes of esophageal stricture in pediatric patients and their response to endoscopic dilatation.Retrospective analysis of clinical and endoscopic data obtained from children and adolescents with esophageal stricture submitted to endoscopic dilatation between July 1993 and January 2003.A total of 125 patients aged between 1 month and 16 years were included in the study. Among the types of stenosis, postoperative (43.2%), corrosive (27.2%) and peptic (21.6%) strictures were the most prevalent. Those patients with corrosive esophageal stricture needed more dilatation sessions. Five cases of esophageal perforation and one case of hemorrhage occurred due to complications during the procedure. Good response to endoscopic treatment was described in 74.4% of cases, but better results were obtained from patients with peptic esophageal stricture.Endoscopic treatment of esophageal strictures in children and adolescents yields good results and has a low rate of complications. Corrosive esophageal strictures have a higher morbidity and require more dilatation sessions.
