Esophageal Ring
Esophageal Ring Definition
An esophageal ring, also known as Schatzki's ring, is a cluster of fiber tissues that surround the lower esophagus. It is not malignant, but it can cause stomach acid reflux to the esophagus during the onset of a hiatus hernia. It can be treated by dilation to allow food to pass down the esophagus towards the stomach.
