Balloon Catheter Dilatation of Benign Esophageal Strictures in Children

Abstract

This retrospective study evaluated the safety and efficacy of fluoroscopically guided balloon dilatation of benign pediatric esophageal strictures. Between 2000 and 2005, 272 esophageal balloon dilatations were performed in 49 children, aged 18 days to 18 years. Chart and primary physician record reviews were used to assess complications, age-appropriate food intake, and dysphagia. Efficacy was calculated by time to recurrent symptoms requiring repeat balloon dilatation. Durability was assessed by the frequency of dilatations. Seventy-seven percent of patients required a second dilatation within 9 months. Survival analysis (Kaplan-Meier) demonstrated no significant difference for efficacy in relation to patient age (P = .76) or stricture cause (P = .56). A decrease in the number of dilatations occurred over time to achieve longer symptom-free intervals. Patients underwent an average of 5.6 dilatations with an average total intervention time of 2 years. Patients were able to remain symptom free for a mean of 110 days. The procedure had a success rate of 100%, the only major complication being an esophageal perforation (complication rate, 0.37%) in a patient with a stricture secondary to correction of a tracheoesophageal fistula. Balloon esophageal dilatation in children is an effective and safe first-line therapy. Complications are quite rare and manageable. Although cures are unusual, most children require less than one dilatation every 6 months. It is concluded that fluoroscopically guided balloon dilatation should be the primary method of treating benign esophageal strictures.
