Esophageal atresia

• Overview

• Treatment

Definition:

Esophageal atresia is a disorder of the digestive system, in which the esophagus does not develop properly. The disorder is a congenital defect, which means it occurs before birth. There are several types of esophageal atresia.

Alternative Names:

Tracheoesophageal fistula

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 and does not connect with the lower esophagus and stomach. In these cases, the top end of the lower esophagus is connected to the windpipe. This connection 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 digestive 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. Immediate surgical repair of this disorder is required so that the lungs are not damaged and the baby can be fed.
