Abstract
Nine patients, 6 weeks to 17 years of age with esophageal atresia (EA), developed esophageal strictures and were treated with 26 balloon catheter dilatations over a period of 3 years; 6 are now asymptomatic. Five of the 9 patients had suspected reflux esophagitis, confirmed in 3 by biopsy and treated medically prior to dilatation. Seven of the 9 patients had a primary anastomosis, 1 a gastric tube, and 1 a colonic interposition. Most dilatations in the group of 7 were performed with balloon (B) ≥ the diameter of the distal esophagus (E) (B/E≥1). The 3 residually symptomatic patients include an infant dilated conservatively (B/E<1) to facilitate later bouginage, 1 patient with a recurrent stricture after stopping medical therapy and home bouginage, and 1 infant who had a persistent anastomotic stricture, suspected but untreated reflux esophagitis, and a perforation during the second balloon dilatation. Balloon catheter esophageal dilatation, as an alternative to bouginage, is usually a safe and effective procedure when reflux esophagitis is diagnosed and treated prior to dilatation.
