Radiofrequency Ablation (RFA) is an FDA-approved endoscopic technique in which diseased tissue is exposed to heat energy and destroyed. Specialists at the Massachusetts General Hospital Barrett’s Esophagus Treatment Center offer RFA to treat Barrett's esophagus. RFA was first used to treat Barrett’s esophagus in 2005. Since then, more than 50 clinical studies have demonstrated the safety and efficacy of RFA for complete removal of Barrett's esophagus, as well as reducing progression of dysplasia to esophageal cancer. These studies have demonstrated successful removal of dysplasia in more than 90% of patients undergoing therapy. Gastroenterologists at the Mass General Barrett's Esophagus Treatment Center have been performing RFA since 2008 and have performed hundreds of successful RFA procedures.
