This research study will look at a newer treatment option for Barrett's Esophagus (BE) which uses nitrous oxide to freeze unwanted tissue. The most commonly used treatment method is Radiofrequency Ablation (RFA) which uses heat to destroy the pre-cancerous tissue. Nitrous Oxide ablation using the C2 CryoBalloon Focal Ablation System, an FDA-cleared…
The purpose of the study is to compare two types of endoscopic treatments in patients with Barretts esophagus (BE) with abnormal cells (dysplasia); radiofrequency ablation (RFA) and hybrid argon plasma coagulation (H-APC). H-APC is a newer technique in the treatment of BE and has not been adequately studied and is not approved by the FDA for routine use.…
