Esophageal Web Or Ring

Etiology

  • Relatively fragile esophageal structures that can interfere w/swallowing. Can be solitary or multiple, with degree of symptoms related to extent of narrowing. Precise cause is unknown.
  • Web: thin mucosal fold that protrudes into lumen. Most occur in the cervical esophagus.
  • Rings (aka Schatzki's ring): thin, concentric mucosal protrusion that typically occurs at/near the gastroesophageal junction. Causes intermittent dysphagia to solids, sometimes associated w/chest discomfort, relieved via regurgitation or by forcing food down w/liquid bolus.

Symptoms

  • Chronic, intermitent
  • Non-or slowly progressive
  • Sensation of food getting stuck → occurring more with larger solids
