Schatzki ring
Alerts and Notices
Synopsis

Patients with esophageal rings often present with dysphagia to solid food, typically meat or bread. When the diameter of rings is less than 13 mm, patients may present with acute food impaction.
Although the clinical presentation can be similar, esophageal webs are caused by normal esophageal mucosa and submucosa growing in a circumferential and obstructive nature within the esophagus.
Esophageal rings are associated with a lower risk of Barrett esophagus, a precancerous condition.
Most esophageal rings can be managed endoscopically with improvement in symptoms. The most severe complications of the rings are food impactions, which require emergent upper endoscopy for food bolus disimpaction, or complications of the endoscopic procedure itself – primarily bleeding, infection, or the risk of perforation.
