Overview
Isolated tracheoesophageal fistula (also called isolated TEF or H-type tracheoesophageal fistula) is a rare birth defect in which there is an abnormal connection (called a fistula) between the trachea (windpipe) and the esophagus (the tube that carries food from the mouth to the stomach). Unlike the more common forms of tracheoesophageal fistula, the isolated type occurs without esophageal atresia — meaning the esophagus is fully formed and continuous, but there is still a small passage linking it to the airway. This abnormal connection allows food, saliva, or stomach contents to pass into the lungs, and air to enter the digestive tract. Babies and children with this condition often experience repeated episodes of coughing or choking during feeding, recurrent lung infections (pneumonia), and abdominal bloating from air entering the stomach. Because the esophagus is intact, this type of fistula can sometimes be harder to diagnose than other forms, and diagnosis may be delayed weeks, months, or even years after birth. The main treatment is surgery to close the abnormal connection between the trachea and esophagus. When diagnosed and repaired early, most children do very well and go on to live normal, healthy lives. After surgery, some children may need follow-up care for breathing or swallowing issues. The condition is considered a congenital anomaly, meaning it develops before birth during the formation of the digestive and respiratory systems.
