Esophagitis and stricture

The esophagus is the tube that carries food and liquid from the mouth to the stomach. The esophagus has a mechanism for preventing the reflux of juices and acid from the stomach back into the esophagus. But when stomach acid and digestive enzymes repeatedly reflux into the esophagus, the tissues become inflamed and ulcerated. This inflammation is known as esophagitis. In some cases, this can lead to ulcers within the esophagus.

When recurrent inflammation occurs in the esophagus, scarring develops. Underlying tissues become fibrous, and the opening of the esophagus near the stomach can narrow. This is known as stricture. In some cases, the opening may be reduced to the diameter of a pencil or smaller. As a result, a large piece of food may completely block the esophagus.
