Value of esophageal impedance monitoring in clinical diagnostics

Introduction: pH-monitoring is the standard diagnostic tool for proving acid regurgitation in gastroesophageal reflux disease (GERD) patients. Multichannel intraluminal impedance (MII) is a new technique for the evaluation of non-acid, volume, liquid or gas reflux, regardless of its acidic content, or combined with pH-metry (pH-MII). Impedance measurement is used to show the bolus transit in the esopahgus (without X-ray). Aims, methods and result: Diagnostic and therapeutic values of pH-MII method were investigated in 2 (F) patients suffering from non-erosive form of GERD (NERD), with atypical extraesophageal sy…
