Halo Barrx is a recent new development in the treatment of Barrett’s esophagus. Barrett’s esophagus is a precancerous change at the end of esophagus related to gastric reflux symptoms. In gastric reflux, the stomach acid refluxes up into the esophagus, causing inflammation. In response to the inflammation, the lining at the end of the esophagus mutates to make itself more resistant to acid. This mutation in the cells results in the Barrett’s esophagus. Overtime, the Barretts esophagus continues to change, ultimately resulting in Esophageal adenocarcinoma. Halo Barrx is an ablation technique where the patient is sedated and undergoes an upper gastrointestinal endoscopy. The Halo Barrx catheter is advanced through the endoscope and cauterizes the Barretts lining to “burn off” the precancerous cells. The procedure takes approximately 20-25 minutes to perform and at most, the patient have have some burning or discomfort in the lower chest/upper abdomen from the cauterization effect. Often a combination of prescription carafate and liquid Tylenol is enough to manage the discomfort. This procedure is often repeated another one or two times to ensure complete eradication of the Barrett’s cells. The procedures, in general, are performed 8 weeks apart.
