Reflux strictures of the esophagus in children

Abstract

Although the therapeutic approach to gastroesophageal reflux in children is well established, there are differences of opinion regarding the management of esophageal strictures, viz bougienage with medical therapy, fundoplication without dilatation, preoperative dilatation followed by fundoplication with intraoperative and postoperative dilatation, or resection and interposition. Sixteen consecutive children (mean age, 30.2 months) with reflux strictures were evaluated, constituting 12% of children operated on for gastroesophageal reflux. The strictures became clinically apparent 22.4 months (mean) from the onset of symptoms and were diagnosed by contrast studies and endoscopy. At first endoscopy all the patients had well-established fibrotic strictures. The strictures were mostly situated in the middle or lower esophagus and 7 were longer than 3 cm in length. All 16 were treated with antacids, H 2-receptor blockers (Cimetidine), prokinetic agents, and intense nutritional resuscitation, together with preoperative stricture dilatations (average, 3.6 times). This was followed by fundoplication when nutritional parameters had been restored, esophagitis improved, and the strictures dilated to adequate size. Seven children required concomitant gastrostomies for prograde esophageal dilatations. Twelve children needed postoperative esophageal dilatations. The results were satisfactory in 14 (88%). Two required endoesophageal resection for localized unyielding strictures. One child responded only after failed reflux surgery was corrected at a second procedure. During an average follow-up of 8.2 years (range, 3 to 11) there has been no stricture recurrence and growth velocity was restored in all. We conclude that our preferred method is preoperative in-hospital management of gastroesophageal reflux with maximum nutritional support and careful evaluation of the degree and extent of esophagitis and fibrous scarring. Antire-flux surgery is delayed until nutritional deficiencies have been corrected, the esophagus adequately dilated, and acute esophagitis controlled. Long-term follow-up with endoscopic surveillance is advocated.
