The 5-year survival rate has been improved, compared with patients who have not undergone routine endoscopic surveillance.
1 Therefore, current practice guidelines recommend endoscopic surveillance of patients with BE in an attempt to detect cancer at an early and potentially curable stage. A cellular atypia confined to the epithelium is called
dysplasia and is considered a histological marker for…
