HALO360 BARRX Radiofrequency Ablation of Barretts Esophagus


HALO360  BARRX Radiofrequency Ablation of Barrett’s Esophagus  

Treatment of Barrett's esophagus using the BARRX HALO360 ablation technique:

Barrett's esophagus is a pre-cancerous condition affecting the lining of the esophagus, the swallowing tube that carries foods and liquids from the mouth to the stomach. It is estimated that 3.3 million adults in the United States will suffer from this condition. This disorder develops when the lining of the esophagus is consistently damaged by stomach acid that continues to cause injury to the esophagus. Our physicians perform the Barrx procedure called the HALO360 which provides a circumferential, 360 degrees, 3 cm long ablation for treating short and long segments of Barrett's epithelium. The components of this system are designed to work together to achieve the removal of the Barrett's tissue in a short, well-tolerated endoscopic procedure with consistent and effective results. If you suffer from consistent symptoms such as heartburn, regurgitation, and chest pain, you may want to schedule an appointment to meet with one of our physicians. 

Five Days Before Procedure:

Please discontinue any coumadin, aspirin, Plavix, or NSAIDS (advil, nuprin, etc.). Tylenol or acetaminophen is o.k.

Preparation for the Procedure:

  1. If your procedure is in the morning, do not eat or drink anything after midnight the night prior to the procedure.
  2. If your procedure is in the afternoon, you may have clear liquids up to 8am (coffee, tea, soda, water, clear juices, clear broth, popsicles and jello).

Purpose of Procedure:

To get rid of the first layer of cells in Barrett’s esophagus (with or without dysplasia) which may progress to esophageal cancer if left untreated. Low heat is applied to the affected area and these cells will shed as with skin peeling after a sunburn. New healthy cells will then replace the Barrett’s cells within the next few weeks and remain healthy as long as the acid reflux is under control.
