Congenital esophageal obstruction by intraluminal mucosal diaphragm

Congenital intraluminal esophageal diaphragm causing complete obstruction is a rare anomaly. By esophagoscopy, a complete membranous diaphragm was demonstrated, perforated, and excised. In the English language literature, this case represents the first report of an isolated membranous atresia at the lower end of the esophagus. A brief review of the world literature and the classification of membranous atresia of the esophagus is discussed.
