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 birth defect of the esophagus that occurs in a small number of people. It causes narrowing of the lower esophagus.
Narrowing of the esophagus may also be caused by:
- Injury

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.
