Schatzki's Ring

Schatzki's Ring

Described by Richard Schatzki, M.D., in 1953, Schatzki’s ring is a narrowing of the lower part of the esophagus caused by changes in the esophageal mucosa (lining of the esophagus).  In the majority of cases, Schatzki’s ring is benign and asymptomatic; the condition is associated with hiatal hernias and can disrupt the normal esophageal functions.

Causes

It has been suggested that long-term gastroesophageal reflux disease causes chronic inflammation and thus chronic damage to the lower esophagus. The damage will heal and form a scar that is the Schatzki’s ring. 

Symptoms

Patients with a Schatzki’s ring are usually asymptomatic. Any symptoms are directly associated with the extent of narrowing caused by the ring. Usually rings of 13 millimeters (0.5 inches) in diameter or narrower are the ones that cause symptoms. Patients can present with severe chest pain and intermittent dysphagia (difficulty swallowing). This condition can cause complete blockage of the esophagus and therefore food impaction. Patients will need to regurgitate the undigested foods to feel better.
