How is management of barett's esophagus?

A. Barrett without dysplasia: surveilled with endoscopy and biopsy every 3 years B. Low-grade dysplasia - Can be surveilled annually or progression to high-grade dysplasia - Endoscopic radiofrequency ablation (RFA) or fundoplication: may cause dysplasia to regress but there has been an inconsistent response C. High-grade dysplasia - Esophagectomy: common management method due to risk of progression to cancer - Endoscopic mucosal resection and RFA: aggressive, but these therapies are in their nascent stages
