Baseline impedance measured during high‐resolution esophageal impedance manometry reliably discriminates GERD patients

Background Baseline impedance measured with ambulatory impedance pH monitoring (MII‐pH) and a mucosal impedance catheter detects gastroesophageal reflux disease (GERD). However, these tools are limited by cost or patient tolerance. We investigated whether baseline impedance measured during high‐reso...

Description
Summary:Background Baseline impedance measured with ambulatory impedance pH monitoring (MII‐pH) and a mucosal impedance catheter detects gastroesophageal reflux disease (GERD). However, these tools are limited by cost or patient tolerance. We investigated whether baseline impedance measured during high‐resolution impedance manometry (HRIM) distinguishes GERD patients from controls. Methods Consecutive patients with clinical HRIM and MII‐pH testing were identified. Gastroesophageal reflux disease was defined by esophageal pH
