Esophageal stenosis due to cartilaginous tracheobronchial remnants

In cases of congenital esophageal stenosis, tracheobronchial remnants in the distal esophagus should be considered a possible diagnosis. The cause is thought to be esophageal sequestration of a tracheobronchial anlage before embryologic separation. Primary resection of the stenotic portion of the esophagus with re-anastomosis is recommended. Such a case is reported.
