Barrx Halo Ablation
Barrx Halo Ablation is a radiofrequency ablation (RFA) therapy that has been shown to be safe and effective for treating Barrett’s esophagus. Radiofrequency energy (radio waves) is delivered via a catheter to the esophagus to remove diseased tissue while minimizing injury to healthy esophagus tissue. This is called ablation, which means the removal or destruction of abnormal tissue.
While you are sedated, a device is inserted through the mouth into the esophagus and used to deliver a controlled level of energy and power to remove a thin layer of diseased tissue. Less than one second of energy removes tissue to a depth of about one millimeter. The ability to provide a controlled amount of heat to diseased tissue is one mechanism by which this therapy has a lower rate of complications than other forms of ablation therapy.
Larger areas of Barrett’s tissue are treated with the balloon-mounted catheter. Smaller areas are treated with the endoscope-mounted catheter. Both are introduced during an upper endoscopy procedure, which is a thin, flexible tube inserted through a patient’s mouth.
