Transient mega-esophagus in a neonate with congenital diaphragmatic hernia.
Esophageal dilatation (ED) in neonates is rare. In the present case, ED was detected in a chest radiograph following repair of congenital diaphragmatic hernia (CDH) in a term neonate. A roentgenographic swallow study on the seventh day of life demonstrated ED and a sub-diaphragmatic stomach. The infant thrived adequately on enteral feeding. A swallow study on the twentieth day of life showed a normal-width esophagus with gastroesophageal reflux and small hiatus hernia. The longstanding herniated stomach in the fetus apparently caused kinking, edema, and obstruction of the gastroesophageal junction. This led to a significant ED and concealment of gastroesophageal reflux. We aim to arouse awareness about the occurrence of ED with CDH, and about its benign course under conservative management.
