Isolated esophageal atresia with spontaneous recanalization: case report

Isolated esophageal atresia is characterized by a long segment between the 2 esophageal pouches. The authors describe a case of pure esophageal atresia that showed spontaneous recanalization in the waiting period for primary esophageal anastomosis. Regurgitation of gastrostomy formula surprisingly was seen in her mouth. The patency of the esophagus was confirmed with thoracic computed tomography (CT) and an esophagogram. A strictured area in the proximal upper third of the esophagus was managed with baloon dilatation. She was discharged in normal condition, feeding by mouth, and with a normal esophagogram. This interesting event led us to speculate about a different type of pure esophageal atresia with the feasibility of the ends recanalizing after some events such as inflammation. This could be the subtype II5 of type 2 in Kluth's atlas of esophageal atresia in which they described 2 blind esophageal ends and a cyst occupying the intervening space. Another speculation about this subject is the presence of double membranes associated with esophageal atresia with a normal outer appearance of the esophagus as was first described by A. F. van Loosbroek.
