MULTICHANNEL INTRALUMINAL IMPEDANCE AND pH.

Esophageal function testing using multichannel intraluminal impedance.

Multichannel intraluminal impedance (MII) is a new technique for evaluation of bolus transport. We evaluated esophageal function using bolus transport time (BTT) and contraction wave velocity (CWV) of liquid, semisolid, and solid boluses. Ten healthy subjects underwent MII swallow evaluation with various boluses of sterile water (pH 5), applesauce, three different sized marshmallows, and iced a...

Multichannel intraluminal impedance and pH-metry for investigation of symptomatic gastroesophageal reflux disease.

BACKGROUND Combined multichannel intraluminal impedance and pH-metry (MII-pH) is a technique that enables monitoring of gastroesophageal reflux independent of its acidity. AIM To investigate the utility of MII-pH in the clinical investigation of patients with gastroesophageal reflux disease (GERD) symptoms. METHODS 32 consecutive patients underwent 24-hour ambulatory MII-pH. 16 patients wer...

Correlation between Reflux and multichannel intraluminal impedance pH monitoring in untreated volunteers.

OBJECTIVES/HYPOTHESIS Although probable causative agents have been identified (e.g., refluxate components, tobacco smoke), the definitive mechanism for inflammation-related laryngeal mucosal damage remains elusive. Multichannel intraluminal impedance combined with pH monitoring (MII/pH) has emerged as a sensitive tool for diagnosis and characterization of gastroesophageal reflux disease with la...
