Evaluation of Tethered Capsule Endomicroscopy as a Screening Tool for Barrett's Esophagus in the Primary Care Setting

Participants will be asked to swallow the TCE device. Participants may use mild numbing spray, and lubrication spray to help swallowing. Imaging will be conducted once the TCE device is past the pharynx. The TCE device will be advanced until the stomach and then slowly pull the TCE back up the esophagus. This may be repeated twice.
