What are the causes of Esophageal Atresia?

Esophageal atresia (EA) is a congenital defect. This means it occurs before birth. There are several types of EA. In most cases, the upper esophagus ends and does not connect with the lower esophagus and stomach.

Most infants with EA have another defect called tracheoesophageal fistula (TEF). This is an abnormal connection between the esophagus and the windpipe (trachea).

Often, infants with EA/TEF also have tracheomalacia. When this occurs, the walls of the trachea are weak and floppy, causing high-pitched or noisy breathing.

At least half of babies with EA/TEF have other defects as well, most often heart defects.

What are the symptoms of Esophageal Atresia?

Symptoms of EA may include:

  • Bluish coloration to the skin (cyanosis), often with attempted feeding
  • Coughing, gagging, and choking with attempted feeding
  • Drooling or vomiting
  • Poor feeding

What are the current treatments for Esophageal Atresia?

EA is an emergency. Surgery is done as soon as possible after birth.

  • First, any connection between the esophagus and the airway must be blocked. This will prevent damage to the lungs.
  • The esophagus will be connected to the stomach. This may take time to complete, depending on the gap between the esophagus and the stomach.

Before the surgery, and for some time afterward, the baby is not fed by mouth. Instead, the baby is fed either:

  • Through a gastrostomy tube (G-tube) so that the baby can be fed directly into the stomach, or
  • Nutrition given through the veins

Care is taken to keep the baby from breathing saliva or other fluids into the lungs.

What is the outlook (prognosis) for Esophageal Atresia?

An early diagnosis gives a better chance of a good outcome.

What are the possible complications of Esophageal Atresia?

The infant may breathe saliva or other fluids into the lungs, causing aspiration pneumonia, choking, and possibly death.

Other complications may include:

  • Feeding problems
  • Reflux (the repeated bringing up of food from the stomach) after surgery
  • Narrowing (stricture) of the esophagus due to scarring from surgery

Prematurity may complicate the condition. As noted above, there may also be defects in other areas of the body.

When should I contact a medical professional for Esophageal Atresia?

This disorder is usually diagnosed shortly after birth.

Contact your baby's provider right away if the baby vomits repeatedly after feedings, or if the baby develops breathing difficulties.
