What is esophageal dilatation?

The esophagus is the tube that carries food and liquid from the mouth to the stomach. If it becomes too narrow, swallowing food or liquid may be difficult. Esophageal dilatation (also called dilation) is a technique used to stretch or open portions of the esophagus that are too narrow.

There are different causes of esophageal strictures (narrowing), including allergies and injury. Your primary physician is responsible for finding out what is causing the problem. He or she will refer you to the interventional radiologist, who will perform the dilatation.

How is esophageal dilatation performed?

Using live X-ray (fluoroscopy) for guidance, a doctor places a flexible wire into the mouth and down the esophagus, past the narrowed area. Then a deflated balloon is threaded over the wire and inflated into a sausage shape to stretch and enlarge the narrowed area. Sometimes more than one balloon will be used. Your child will be protected by an X-ray shield during this procedure.

Will my child be awake for the procedure?

No. All children are given general anesthesia for the procedure.

What are the risks of esophageal dilatation?

The procedure is considered low-risk. However, potential complications include:

Will my child have pain after the procedure?
