What does esophageal ulcer scar change mean?

Esophageal ulcer scar changes refers to the formation of scar tissue on the esophageal mucosa, usually caused by long-term esophageal ulcer.

Esophageal ulcer refers to the ulcerative lesions in the inner mucosa of the esophagus, usually caused by acid reflux, esophageal inflammation, infection and other factors leading to damage to the esophageal mucosa, surface tissue rupture, forming ulcers. When esophageal ulcer heals, scar tissue will gradually form around the ulcer area. Scar is the body's natural reaction to repair damaged tissue, its main component is collagen fibers. Scar tissue is different from normal tissue structure, usually relatively rigid. The scar tissue formed after esophageal ulcer healing can affect the function of esophagus to some extent, resulting in reduced elasticity and tension of esophagus, which may affect food passage.
