Esophageal dysfunction has been reported after successful repair of esophageal atresia but its nature has not been clearly defined. We studied esophageal motility in 20 newborns with esophageal atresia by recording intraluminal pressure of both proximal and distal segments. The investigation was made by pressure monitoring of the upper pouch via the mouth and of the distal segment via the gastrostomy. In all cases we found motility disorders. Two patients (12.5%) showed incomplete relaxation of the upper esophageal sphincter. The resting pressure of the esophageal body in both segments was constantly positive in all cases. Lower esophageal sphincter (LES) function was normal in all but two patients (16.7%) in whom the LES pressure was reduced and one case (8.4%) with incomplete relaxation of the LES. These studies suggest that motility disorders are also present in esophageal atresia before surgery.

Abstract

Esophageal dysfunction has been reported after successful repair of esophageal atresia but its nature has not been clearly defined. We studied esophageal motility in 20 newborns with esophageal atresia by recording intraluminal pressure of both proximal and distal segments. The investigation was made by pressure monitoring of the upper pouch via the mouth and of the distal segment via the gastrostomy. In all cases we found motility disorders. Two patients (12.5%) showed incomplete relaxation of the upper esophageal sphincter. The resting pressure of the esophageal body in both segments was constantly positive in all cases. Lower esophageal sphincter (LES) function was normal in all but two patients (16.7%) in whom the LES pressure was reduced and one case (8.4%) with incomplete relaxation of the LES. These studies suggest that motility disorders are also present in esophageal atresia before surgery.
