About this study

Patients undergoing ablative therapy for management of dysplastic Barrett's Esophagus (BE) will have decreased distensibility over the course of treatment, but improvement in mucosal impedance as BE epithelia is replaced by neosquamous epithelia. This information may lead to further research in predicting therapeutic response and complications. The purpose of this research is to collect information while measuring changes related to the esophagus in patients that receive radiofrequency ablation (RFA) for dysplastic Barrett's Esophagus (BE) or esophageal cancer. Study participation includes measurements of the esophagus with the use of two different devices. This takes place during clinically indicated upper endoscopies during the timeframe the participant is receiving RFA treatments. This process will take up to an additional 10 minutes during the upper endoscopy and be done while the participant is sedated.
