Abstract

Tracheobronchial remnants and formation of cartilaginous ring are rare causes of congenital esophagealstenosis. Symptoms are nonspecific and many patients with presumed congenital esophageal stenosis subsequentlyhave been demonstrated to have inflammatory stricture due to hiatus hernia or esophagitis. Characteristicradiological findings of this disease are linear intramural clefts projecting from the are of stenosis and theseclefts represent pathologically communicating intramural cystic spaces lined by respiratory epithelium. Resistanceot instrumental dilatation and the absence of inflammatory mucosal changes are characteristic endoscopic findings.Authors experienced 3 cases of tracheobronchial remnant associated with esophageal stenosis(2 cases) andesophageal duplication with tracheobronchial remnants in gastric fundus from 1974 until recently.
