Long-term esophageal function following repair of esophageal atresia.

Abstract

Primary repair of esophageal atresia restores gastrointestinal continuity, but does not ensure normal esophageal function. To date 22 patients, six to 32 (average 15) years after repair of their esophageal atresias, have been evaluated by personal interview and esophageal manometrics and acid reflux testing. Previous barium swallow examinations had demonstrated varying degrees of anastomotic narrowing (12 patients), abnormal esophageal motor function (11 patients), gastroesophageal reflux (two patients), and hiatal hernia (one patient). Ten patients experience intermittent dysphagia for solid foods. Seven have typical symptoms of gastroesophageal reflux. Esophageal function tests including manometry and intraesophageal pH recording, have demonstrated varying abnormalities of esophageal motility in 21 patients and moderate to severe gastroesophageal reflux in 13. Two patients have required reconstruction of the esophagogastric junction for control of severe reflux esophagitis. The unexpected high incidence of gastroesophageal reflux in these patients, coupled with their abnormal esophageal motility which impairs normal acid clearing, renders them more prone to reflux esophagitis. Careful long-term evaluation for gastroesophageal reflux and its complications is indicated following primary repair of esophageal atresia. Evaluation of esophageal function with intraesophageal pressure and pH recordings is a far more sensitive indicator of esophageal physiology than the barium swallow examination.
