Barrx (RFA Therapy for Barrett’s Esophagus)

What is Barrx RFA Therapy?

Barrett’s esophagus is a condition in which the esophagus becomes damaged and inflamed by acid reflux. It is associated with an increased risk of esophageal cancer, which is why it is important for these patients to undergo regular checkups, imaging tests and biopsies to check for the presence of precancerous cells. In cases where precancerous cells are identified, the Barrx RFA therapy is a treatment option.

Radiofrequency ablation (RFA) uses heat to remove precancerous tissue damaged by Barrett’s esophagus. The Barrx radiofrequency ablation system technology is designed for the removal of tissue affected by Barrett’s, while preserving the underlying healthy tissue. As the esophagus heals, healthy squamous cells replace the unhealthy cells, helping to prevent progression toward cancer.

How is Barrx RFA Therapy Performed?

This procedure is typically performed under sedation to ensure your comfort.  An endoscope with a needle-like probe will be inserted into the body, and radiofrequency waves will be sent out, causing nearby cells to die. The immune system will naturally remove these dead cells. This treatment typically takes 30 minutes to complete, though may be longer depending on the specific case.

Some patients may need 2-3 treatment sessions over the course of 4-12 months depending on the size of the affected area.

I felt heard. I truly appreciated Dr. Ende's bedside manner and how he really took the time to listen to my whole health picture. It meant a lot to me.

The front staff was immediately attentive as soon as I walked in. The nurses and PAs were professional and very nice, and the doctors were even better. The procedure went smoothly and could not have gone better. Of course, having positive lab results makes it easier to post a glowing report but I got the impression that if I had been diagnosed differently, they would have taken care of me with the same kindness and dedication.
