Barrett's epithelium is a term used to describe a change in the lining of the lower esophagus. Normally, the esophagus is lined by pink, squamous type epithelium (lining) and the stomach is lined by darker, reddish, columnar type epithelium. When the lower esophagus is damaged by acid, its pink lining can be replaced by the darker, reddish lining.
If the lining on biopsy appears more like the intestinal lining, it is called intestinal metaplasia. Intestinal metaplasia has been associated with the development of esophageal adnocarcinoma (cancer) of the lower esophagus. For all practical purposes, Barrett's esophagus and Barrett's epithelium are the same thing.
It is controversial whether Barrett's esophagus can revert to a normal lining (mucosa).
Currently patients with Barrett's esophagus are screened by endoscopy and biopsy every two years to verify that there has been no evolution towards malignant change of the mucosa.
I strongly encourage you to continue with your screening at least every 2 years and sooner if you feel you need.
