Barrett's Esophagus is classified into two types: non-dysplastic Barrett's Esophagus and dysplastic Barrett's Esophagus.
- Non-dysplastic Barrett's Esophagus: This benign condition is characterized by replacing the normal lining of the Esophagus with columnar cells. It is further classified into three types based on the type of columnar cells present: gastric cardia-type, gastric fundic-type, and intestinal metaplasia-type.
- Dysplastic Barrett's Esophagus: is a pre-cancerous condition where the abnormal cells can become cancerous. It is further classified into low-grade dysplasia, high-grade dysplasia, and intramucosal carcinoma.
Diagnosing the type of Barrett's disease is critical for treatment planning and managing Barrett's Esophagus. Patients with non-dysplastic Barrett's Esophagus have a lower risk of developing oesophagal cancer than those with dysplastic Barrett's Esophagus.
