Mid-esophageal mucosal impedance reflects mucosal integrity and phenotypes refractory reflux-like symptoms

Key Points

• The aim is to explore how mid-esophageal mucosal impedance relates to mucosal integrity and classifications of patients with reflux-like symptoms.
• Assessment of mid-esophageal mucosal impedance
• Comparison with conventional reflux testing
• Analysis of mucosal integrity in varied patient groups
• Impedance measurements correlate with mucosal integrity.
• Identify patients with phenotypes experiencing refractory reflux-like symptoms.
• Suggest location-specific impedance assessment as a complementary diagnostic tool.
