Definition of Lower 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, incidence, and risk factors

For most people, lower esophageal ring does not cause symptoms.
Signs and tests
Tests that show the lower esophageal ring include:
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.
Swallowing problems may return. Repeated treatments may be needed.
