There are several synonyms for the term "esophageal web," which refers to a condition where a thin membrane or layer of tissue forms in the esophagus. Some of the common synonyms include esophageal stricture, Schatzki's ring, and plummer-vinson syndrome. Esophageal stricture refers to a narrowing of the esophagus due to scar tissue or inflammation, while Schatzki's ring is a narrow band of tissue that develops at the lower end of the esophagus. Plummer-Vinson syndrome is a rare condition that occurs when webs develop near the upper end of the esophagus, leading to difficulty swallowing. Regardless of the type, esophageal webs can cause significant discomfort and difficulty eating, and may require medical intervention to resolve.
