Circumferential ablation of Barrett's esophagus that contains high-grade dysplasia: a U.S. Multicenter Registry.

Background: The management strategies for Barrett's esophagus (BE) that contains high-grade dysplasia (HGD) include intensive endoscopic surveillance, photodynamic therapy, thermal ablation, EMR, and esophagectomy.

Objective: To assess the safety and effectiveness of endoscopic circumferential balloon-based ablation by using radiofrequency energy for treating BE HGD.

Design: Multicenter U.
