All patients should be treated with medications to decrease acid reflux into the esophagus. Some patients with dysplasia or early stage esophageal cancer may be candidates to have an endoscopic procedure called ablation to remove the diseased tissue to avoid progression to cancer. BARRX is a procedure performed during upper endoscopy to ablate (or coagulate) abnormal Barrett’s tissue by heating it until it is no longer viable or alive. Cryospray Ablation is a procedure performed during upper endoscopy. This technique removes unwanted tissue by freezing it with a spray of liquid nitrogen.
