Radiofreqeuncy ablation and complete endoscopic resection equally effective for dysplastic Barrett's esophagus
Date:5/21/2014

DOWNERS GROVE, Ill. May 21, 2014 According to a new systematic review article, radiofrequency ablation and complete endoscopic resection are equally effective in the short-term treatment of dysplastic Barrett's esophagus, but adverse event rates are higher with complete endoscopic resection. The article comparing the two treatments appears in the May issue of GIE: Gastrointestinal Endoscopy, the monthly peer-reviewed scientific journal of the American Society for Gastrointestinal Endoscopy (ASGE).

Barrett's esophagus is a condition in which the lining of the esophagus changes and becomes more like the lining of the small intestine. It is believed that Barrett's esophagus (BE) occurs because of chronic inflammation resulting from long-standing Gastroesophageal Reflux Disease (GERD). Barrett's esophagus is more common in Caucasian males older than the age of 50 who have had GERD for greater than five years. Most patients with Barrett's esophagus will not develop cancer. However, in some patients further precancerous change in the tissue, called dysplasia, will develop. Those patients that develop dysplasia, especially high grade dysplasia, are significantly more likely to develop esophageal cancer.

Esophagectomy (surgery to remove part or all of the esophagus) has previously been the recommended treatment for BE with high grade dysplasia (HGD) or intramucosal cancer (cancer limited to the most superficial layer of the esophagus), but this surgery is associated with significant morbidity and mortality. As a result, endoscopic therapies for treatment of HGD or superficial cancers have been developed which minimize treatment-related morbidity. Ideally, endoscopic treatments need to target the entire segment of Barrett's mucosa (lining of the esophagus) in order to maximally reduce the risk of developing esophageal cancer.

To date, two distinct endoscopic approaches have been widely used for this purpose. The first is complete
