Lower esophageal ring

Esophagogastric ring; Schatzki's ring; Dysphagia - esophageal ring; Swallowing problems - esophageal ring

A lower esophageal ring is an abnormal ring of tissue that forms where the esophagus (the tube from the mouth to the stomach) and stomach meet.

Causes

A lower esophageal ring is a narrowing of the esophagus that occurs in a small number of people. The cause of the problem is unclear, but many believe that it is caused by acid reflux.

Narrowing of the esophagus may also be caused by:

Symptoms

For most people, a lower esophageal ring does not cause symptoms.

The most common symptom is the feeling that food (especially solid food) is stuck in the lower neck or under the breastbone (sternum).

Exams and Tests

Tests that show the lower esophageal ring include:

Treatment

A device called a dilator is passed through the narrowed area to stretch the ring. Sometimes, a balloon is placed in the area and inflated, to help widen (dilate) the ring.

Outlook (Prognosis)

Swallowing problems may return. You may need repeat treatment.

When to Contact a Medical Professional

Contact your health care provider if you have swallowing problems.

  • Schatzki ring - x-ray - illustration

    A solution containing a dye (barium), which is visible on x-rays, has been swallowed (upper GI series) and x-rays have been taken of the esophagus. There is a narrowing near the stomach (indicated by the arrow). This non-cancerous ring of tissue (Shatzki ring) may cause swallowing problems (dysphagia) and can be treated with dilation of the stricture.
