About HALO Radiofrequency Ablation


HALO radiofrequency ablation is an outpatient procedure that delivers bursts of heat-energy in a very precise and controlled manner to remove pre-cancerous cells in the esophagus without damaging the lining or underlying structure, thus protecting the healthy tissue and cells.


Our experienced team has been performing approximately 30 to 40 cases annually since 2007. The procedure is often performed in conjunction with endoscopic mucosal resection (EMR).
