Barrett's esophagus - Definition

Ask a question


Barrett's esophagus is the cellular reorganization that occurs at the base of the esophagus. The esophageal tissue is gradually replaced by a form of intestinal mucus membrane that does not belong there. This type of pathology may be due to chronic gastroesophageal reflux which, in irritating the esophagus, leads it to protect itself by establishing new cells. Men are more affected by Barrett's esophagus, particularly when they are around 60 years old. Barrett's esophagus can be complicated by ulceration or cancer in the base of the esophagus.
