BARRX is a minimally invasive endoscopic procedure that is able to successfully treat Barrett’s esophagus, thus minimizing the patients risk for developing esophageal cancer. Barrett’s esophagus is a serious condition that is often the result of frequent heartburn that is generally caused by Gastroesophageal Reflux Disease, or GERD. The BARRX procedure treats Barrett’s esophagus by removing the abnormality in the tissue of the esophageal lining. This is completed in an outpatient procedure with the use of an endoscope.
The first step of BARRX procedure is the placement of a sizing balloon into your esophagus. The dilated balloon is attached to the tip of a catheter that is inserted into your esophagus alongside the endoscope. Once the catheter and balloon are successfully within the esophagus near the area in need of treatment the balloon is inflated. The balloon, together with a HALO energy generator are able to correctly measure the diameter of your esophagus, which allows your physician to choose the best treatment catheter for your needs. Once this is accomplished the sizing balloon will be removed and the HALO ablation catheter is inserted in its place.
Much like the catheter used to measure your esophagus, the HALO ablation catheter also has a balloon at its tip. This balloon however is used in the treatment of the abnormal tissue due to the band of radiofrequency electrodes that surrounds it. The HALO Energy Generator and ablation catheter treat the abnormal tissue by delivering a short burst of energy to the circumference of your esophagus. This burst of energy is delivered at 360 degrees and removes the diseased tissue that causes Barrett’s esophagus, therefore reducing your risk of developing esophageal cancer.
