Mucosal Impedance and Eosinophilic Esophagitis

Overview

About this study

Do patients with eosinophilic esophagitis have baseline increased esophageal mucosal impedance? And will treatment that reverses esophageal eosinophilia in patients, correct abnormalities in mucosal impedance?

  • Patients undergoing clinically indicated upper endoscopy for indications other than dysphagia or GERD with normal appearing esophageal mucosa.

 Exclusion criteria:

  • Medical conditions such as severe heart or lung disease that preclude safe performance of endoscopy
