Prolonged 2-Day Esophageal pH-Metry with Impedance Monitoring Improves Symptom-Reflux Association Analysis

Combined pH-metry/impedance monitoring increases the diagnostic yield in patients with atypical gastroesophageal reflux symptoms.

BACKGROUND Globus sensations, hoarseness and chronic cough are suggested to be atypical manifestations of Gastroesophageal Reflux Disease (GERD). The aim of the study was to investigate whether combined pH-metry and multichannel intraluminal impedance monitoring increases the diagnostic yield. METHODS 41 patients with atypical GERD symptoms were included in the study. Globus sensation was the...

Impedance pH Monitoring: Intra-observer and Inter-observer Agreement and Usefulness of a Rapid Analysis of Symptom Reflux Association

BACKGROUND/AIMS Symptom reflux association analysis is especially helpful for evaluation and management of proton pump inhibitor (PPI) re-fractory patients. An accurate calculation requires manual editing of 24-hour multichannel intraluminal impedance-pH (MII-pH) tracings after automatic analysis. Intra- and inter-observer agreement as well as reliability of rapid editing confined to the time a...

Combined Dual Channel Impedance/pH-metry in Patients With Suspected Laryngopharyngeal Reflux

BACKGROUND/AIMS Laryngopharyngeal symptoms of gastroesophageal reflux disease (GERD) such as globus sensation, hoarseness and chronic cough are becoming increasingly recognized. This study was aimed to investigate the diagnostic usefulness of combined dual channel multichannel intraluminal impedance (MII)/pH-metry in 'off-proton pump inhibitor (PPI)' patients with suspected laryngopharyngeal re...

How to Interpret Esophageal Impedance pH Monitoring

Esophageal impedance pH monitoring provides quantitative data on esophageal acid exposure and has the ability to correlate the symptoms with acid exposure events. The nomenclature for the reflux patterns detected in impedance pH monitoring as well as the normal values have been determined. Data interpretation is similar to 24-hour pH monitoring, ie, searching for an increase in the number of re...
