Lower esophageal ring
Definition
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.
Alternative Names
Esophagogastric ring; Schatzki's ring
Causes, incidence, and risk factors
A lower esophageal ring is a birth defect of the esophagus that occurs in 4% of people. It causes narrowing of the lower esophagus.
Narrowing of the esophagus may also be caused by:
- Injury
- Tumors
- Other causes (See: Esophageal stricture)
Symptoms
For most people, lower esophageal ring does not cause symptoms.
The most common symptom is a sensation that food, especially solids, is stuck in the lower neck or under the breastbone (sternum) when it is swallowed.
Signs and tests
Tests that show the lower esophageal ring include:
- EGD (esophagogastroduodenoscopy)
- Upper GI (x-ray with barium)
Treatment
Treatment involves stretching the ring by passing a device called a dilator through the area. Sometimes, a balloon is placed in the area and inflated, which helps widen the abnormal ring.
Support Groups
Expectations (prognosis)
Swallowing problems may return. Repeated treatments may be needed.
Calling your health care provider
Call for an appointment with your health care provider if you have swallowing problems.
