Definition: A Schatzki ring or Schatzki–Gary ring is a narrowing of the lower esophagus that can cause difficulty swallowing (dysphagia). The narrowing is caused by a ring of mucosal tissue (which lines the esophagus) or muscular tissue.

A Schatzki ring is a specific type of "esophageal ring", and Schatzki rings are further subdivided into those above the esophagus/stomach junction (A rings), and those found at the squamocolumnar junction in the lower esophagus (B rings).

Patients with Schatzki rings can develop intermittent difficulty swallowing or, more seriously, a completely blocked esophagus.


- Smooth, concentric narrowing of the lumen at the esophagogastric junction.
- Schatzki ring is often seen in the setting of reflux esophagitis.
