Congenital and acquired tracheoesophageal fistulas in children.

Tracheoesophageal fistulas (TEF) are an anomalous communication between airway and esophagus. There are several types of TEF. Congenital are mainly associated to an esophageal atresia. The type III or C, in which the upper segment of the esophagus ends in a blind pouch and there is distal tracheoesophageal fistula above the carina, accounts for 85% of esophageal atresias. The other are extremely infrequent. H-type or N-type TEF, classified as type 5 or E, is an uncommon variant and accounts for less than 4%. Recurrent TEF is a serious complication after first surgery of esophageal atresia and TEF. The rate of recurrence of TEF is estimated between 3-15%. The treatment is a challenge with a high rate of recurrence after surgery. Classical symptoms of RTEF include coughing especially after drinking, abdominal distension, repeated cyanosis, and respiratory infections. In the case of H-type fistula the symptoms are similar but appear during the first month of life. In this chapter we presented the management and alternative treatments of the congenital and acquired TEF.
