This document discusses endoscopic techniques for treating Barrett's esophagus, including radiofrequency ablation (RFA) and endoscopic mucosal resection (EMR). It emphasizes that technique is important for adequate treatment. RFA and EMR have been shown to be effective at eliminating dysplasia and intestinal metaplasia in Barrett's esophagus. However, treatment requires long-term follow up due to the risk of buried glands and recurrence. Selection of appropriate patients is also key.
