A Schatzki ring , also called Schatzki-Gary ring , is symptomatically narrow esophageal B-ring occurring in the distal esophagus and usually associated with a hiatus hernia. Most commonly it presents as intermittent dysphagia, especially to solid food. A history of food impaction is also very common. Dysphagia is more common in patients with an associated motility disorder. The pathogenesis of the Schatzki ring is unclear with conflicting hypotheses that include redundant pleats of mucosa, congenital abnormalities and modified peptic strictures.

Interestingly, there is a reduced incidence of Barrett esophagus in patients with a Schatzki ring. Depending on its luminal diameter, an esophageal B-ring may be symptomatic or asymptomatic 4 :. Schatzki rings are located at the gastro-esophageal junction, illustrated by the fact that there is squamous epithelium above and columnar epithelial below the ring.

Schatzki ring

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. Patients with Schatzki rings can develop intermittent difficulty swallowing or, more seriously, a completely blocked esophagus. The ring is named after the German-American physician Richard Schatzki. Not all patients with Schatzki rings have symptoms; barium swallow tests of the esophagus sometimes show Schatzki rings in patients with no swallowing difficulties.
