Esophageal dilatation and reflux in neonates supported by ECMO after diaphragmatic hernia repair.
Extracorporeal membrane oxygenation (ECMO) for survivors of surgical repair of congenital diaphragmatic hernia was used in 14 neonates. All showed marked esophageal dilatation on postoperative chest radiographs; the dilated esophagus simulated an air- or fluid-filled mass. All patients were later shown to have marked gastroesophageal reflux as well. The finding suggests a problem in swallowing exists before birth, which may explain the recent correlation between diaphragmatic hernia and hydramnios. The observation of a mediastinal mass in neonates with congenital diaphragmatic hernia may represent esophageal ectasia and may be related to significant gastroesophageal reflux.
