Causes, incidence, and risk factors:

The esophagus is the tube that normally carries food from the mouth to the stomach. In most cases of esophageal atresia, the upper esophagus ends blindly and does not connect with the lower esophagus and stomach. In these cases, the top end of the lower esophagus is connected with the trachea (windpipe). This connection between the lower esophagus and the trachea is called a tracheoesophageal fistula (often abbreviated TEF).

Over 30% of people affected by this condition will also have other abnormalities, such as heart disorders or other gastrointestinal tract disorders. Other types of esophageal atresia involve narrowing of the esophagus and may also be associated with other birth defects.

This condition is frequently complicated by the infant's breathing saliva and secretions into the lungs, causing pneumonia, choking, and possibly death. It is considered a surgical emergency.

The disorder is usually detected shortly after birth when feeding is attempted and the infant coughs, chokes, and turns blue (cyanosis). Immediate surgical repair of this disorder is required so that the lungs are not damaged and the baby can be fed.
