Barrett's Esophagus Definition
Definition
Barrett's esophagus is a complication of chronic esophagitis, which is inflammation of the esophagus.
Barrett's esophagus is characterized by a change in the cells lining the esophagus. Normal cells are flat-shaped (squamous) cells, while Barrett's esophagus cells are shaped like a column. This cell change is called metaplasia . It is a premalignant phase that may eventually result in cancer of the esophagus if untreated.
