Barrett esophagus (British English: Barrett’s oesophagus) sometimes called Barrett syndrome or columnar epithelium lined lower oesophagus (CELLO) refers to an abnormal change (metaplasia) in the cells of the lower portion of the esophagus. When the normal stratified squamous epithelium lining of the esophagus is replaced by simple columnar epithelium with goblet cells (cells usually found lower in the gastrointestinal tract) Barrett’s esophagus is diagnosed.
