Esophageal and Gastric Diseases Ambulatory 24 - hour Esophageal pH Monitoring

The incidence of gastroesophageal reflux disease (GERD) is increasing and if left untreated can lead to significant patient morbidity and even death. The disease results from the abnormal reflux of gastric contents into the distal esophagus causing symptoms in most and subsequent mucosal damage in some. Several investigations can be used to confirm the diagnosis, but most are dependent on the p...

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...

Ambulatory esophageal pH monitoring: new directions.

pH testing remains a commonly used evaluative tool in clinical practice. However, the original tool that included a nasally placed pH catheter was plagued with a variety of shortcomings, primarily the effect of the procedure on patients' lifestyle and thus on reflux-provoking activities. The miniaturization of evaluative techniques in gastroenterology was the impetus for the development of the ...

Esophageal pH and Combined Impedance-pH Monitoring in Children

Esophageal pH monitoring is considered the gold standard for the diagnosis of gastroesophageal reflux disease because of the normal ranges across the pediatric age range. However, this method can only detect acid reflux. Multichannel intraluminal impedance-pH (MII-pH) monitoring has recently been used for the detection of bolus reflux in infants and children. This method allows for the detectio...
