| Abstract |
|
Esophageal stenosis due to tracheobronchial remnants is a rare cause of congenital esophageal stenosis. The cause is thought to be esophageal sequestration of tracheobronchial remnants during embryonic separation. Errors in diagnosis are common and high index of suspicion is required for accurate diagnosis, and resection of primary site with anastomosis is recommanded. Although a rare entity, esophageal stenosis due to tracheobronchial remnants should be considered in patients with esophageal stenosis, when esophageal stenosis fails to respond to standard therapy including bougienage and balloon dilatation, and esophagoscopy shows normal mucosa on the stenotic segment.
Four cases of congenital esophageal stenosis due to tracheobronchial remnants were reported, the first case without accompanied anomaly, the second case accompanied by tracheoesophageal fistula, the third case accompanied by Down syndrome, and the last case accompanied by tracheoesophageal fistula and congenital heart disease. |
