Congenital distal esophageal obstruction caused by intraluminal mucosal web.

Congenital intraluminal mucosal web of the esophagus is a very rare type of esophageal atresia. There are two types of this abnormality: the isolated esophageal membranous atresia and the esophageal membranous atresia with tracheoesophageal fistula. In the isolated esophageal membranous atresia, the esophageal appearance is externally normal in surgical exploration. Previously, only a few cases with an obstructing web had been reported1-5. The choices of treatment are excision by esophagotomy and/or gastrotomy, thoracoabdominal approach or endoscopic perforation of the web and dilatation.
