Abstract
A Schatzki ring also known as Schatzki–Gary ring is a narrowing of the lower esophagus that can cause dysphagia. The narrowing is caused by a ring of mucosal tissue which lines the esophagus or muscular tissue. Schatzki ring was first observed in asymptomatic patient in 1944 by Richard Schatzki who was a renowned radiologist. A Schatzki ring is a specific type of "esophageal ring". Schatzki ring is described as a circular membrane of submucosa or mucosa or appear as a thin membranous structure that does not contain any muscularis propria. It is restricted to squamocolumnar junction at the esophagogastric junction. In this article, we will discuss Schatzki ring as a cause of dysphagia, its symptoms, associated presentations, differential diagnosis, treatment, and management.
