Tracheoesophageal Fistula

What is TEF?

There are four types of Tracheoesophageal abnormalities.

Type B: Esophageal Atresia with Tracheoesophageal Fistula. The upper segment of the esophagus forms a fistula (connection) with the trachea. The lower segment leads from the stomach to a blind pouch.

Type C: Esophageal Atresia with Tracheoesophageal Fistula. The upper segment of the esophagus ends in a blind pouch, whereas the lower segment attaches from the trachea to the stomach.

Type D: Esophageal Atresia with Tracheoesophageal Fistula. The upper segment of the esophagus forms a fistula with the trachea, similar to Type B. The lower segment, however, connects from the trachea to the stomach.

Type H: Tracheoesophageal Fistula. Unlike the previous types, the esophagus does connect from the mouth to the stomach. A connection is made, however, between the trachea and the esophagus.
