Balloon catheter dilatation of peptic pyloric stenosis in children.

In the past 3 years, three children (ages 2, 4, and 8 years) suffering from peptic pyloric stenosis and repeated vomiting were treated in our department with balloon dilatation followed by H2-receptor antagonist therapy. After the dilatation, all three patients could take solid food without vomiting. There were no complications as a result of the procedures. During a mean follow-up of 17 months (range, 5-30) there was no recurrence of symptoms. The method of dilatation is described, and we recommend it as an option for the initial nonoperative treatment of pediatric peptic pyloric stenosis. The long-term results of balloon dilatation of peptic pyloric stenosis will, however, require further evaluation.
