Following are features of Barrett&;s oesophagus
Histologic changes of the distal oesophagal mucosa from its normal squamous epithelium to a columnar configuration (intestinal metaplasia). Barrett oesophagus in endoscopy appears as velvety-red "tongues" of mucosa that extend cephalad from the GEJ. These patients carry a higher risk to Adenocarcinoma oesophagus compared to normal population. Reference: Sabiston 20th edition page: 1074
