Since Barrett's (and its related concern, esophageal cancer) is a concern for sleevers, this is promising.

ScienceDaily (Aug. 11, 2011) — Radiofrequency ablation (RFA) is a safe and effective option for the treatment of dysplastic Barrett's esophagus that attains lasting response, according to a new study inGastroenterology, the official journal of the American Gastroenterological Association. Progression of disease, which can precede cancer, was rare in patients who underwent RFA treatment, and there was no procedure- or cancer-related mortality.

RFA is a minimally invasive treatment alternative for dysplastic Barrett's esophagus in which the inner lining of the esophagus, which contains the precancerous cells, is destroyed by applying high radiofrequency waves to it, causing a thermal injury or "burn." When these precancerous cells are destroyed, normal tissue usually regenerates in its place.

Study results demonstrated that more than 90 percent of the 119 patients treated with RFA demonstrated complete eradication of abnormal pre-cancerous cells and intestinal metaplasia (cells similar to those lining the intestine) at an average follow-up of greater than three years.

That's a great post which I'm book marking. Thanks!
