Endoscopy in esophageal atresia and tracheoesophageal fistula.

Between 1970 and 1979 152 infants born with the anomaly of esophageal atresia with or without tracheoesophageal fistula or of congenital tracheoesophageal fistula without atresia were treated at the Royal Alexandra Hospital for Children, Sydney. Recent developments in endoscopic equipment and new techniques of anesthesia allow detailed examination of the respiratory tract and esophagus with minimum trauma and maximum safety. Symptomatology relating to the airway and to the esophagus after surgical repair often occurs in patients who may have tracheomalacia, esophageal anastomotic stricture, esophageal reflux and sometimes recurrent or residual fistula. A definite diagnosis of tracheomalacia can be made by finding the typical triad of anteroposterior narrowing of the tracheal lumen, weakening of the semicircular-shaped cartilages and forward ballooning of the widened posterior membranous tracheal wall. Careful examination of the trachea and esophagus allows identification of an elusive recurrent fistula or an H-type fistula. As the primary results of surgery for esophageal atresia and tracheoesophageal fistula improve, long-term problems are becoming increasingly important. The role of the pediatric endoscopist is vital in the care of these patients.
