New Barrett's Esophagus Treatment Now Available

An effective and safe technology for treating Barrett’s esophagus, including long segment BE and areas with dysplasia, has been added to our list of endoscopic procedures, as a FDA approved technique, and is available to our patients at this time.

The BARRX RF ablation system is designed to remove the Barrett’s esophageal epithelium in a short endoscopic procedure that patients tolerate well and that reduce risks of progression to CANCER.

This technique provides a uniform and controlled ablative therapy at a consistent depth. It can remove the layer of diseased tissue while sparing healthy underlying tissue. This allows regrowth of new, healthy tissue within 8 weeks.

This innovative endoscopic procedure will replace the “watch and wait” Barrett’s esophagus management protocol with a “diagnose and treat” standard of care.

Please contact our office for initial evaluation and coordinated protocol of treatment to be offered to you . We will be more than happy to assist you.

Q - I have a long history of heartburn and my physician told me I could have Barrett's esophagus. What is this?

A - This is a condition in which the inner lining of the esophagus is replaced by tissue that is similar to the lining of the intestine, a process calle intestinal metaplasia. Barrett's esophagus affects about 1 percent of the adults in the United States and is diagnosed by EGD (upper endoscopy) with biopsy. The condition is found about three to five times more often in people who also have acid reflux disease. Therefore, we recommend treating acid reflux symptoms with acid-reducing drugs. People with Barrett's esophagus are at risk for developing cancer and therefore, patients should undergo repeat EGD at regular intervals.


Premier Endoscopy Center Savings (continued)

Independent surgery centers procedures are covered by Medicare and other insurance’s. Especially now that many patients have very high deductible’s these cost savings go directly to the patient. Today, payments under the formula are on average are about 67 percent of what the rates would be for the same procedure at an outpatient surgical center in a hospital. You have the right to ask what a Hospital is going to charge you for a procedure !! Having your procedure at Premier Endoscopy Center will save Patient’s, Insurance companies and reduce the overall cost of health care for all Americans!!
