Assessment of Esophageal Epithelium Integrity With Use of a Novel Mucosal Impedance Device

Enrolling by invitation

The objective of this study is to design and use a novel, minimally invasive mucosal impedance (MI) technology to inexpensively and accurately test mucosal health in suspected gastroesophageal reflux disease (GERD) and nonerosive reflux disease (NERD) patients as compared to those without GERD.
