MULTICHANNEL INTRALUMINAL IMPEDANCE AND pH.

Correlation of Gastroesophageal reflux disease Assessment Symptom Questionnaire to impedance-pH measurements in children

Background Esophageal multichannel intraluminal impedance-pH monitoring has become one of the preferred tests to correlate observed reflux-like behaviors with esophageal reflux events. The Gastroesophageal reflux disease Assessment Symptom Questionnaire is a validated tool used to distinguish infants with gastroesophageal reflux disease from healthy children. The aim of this study was to determ...

Esophageal Multichannel Intraluminal Impedance and pH Monitoring in the Evaluation of Achalasia and Gastroesophageal Reflux Disease in a Child with Down Syndrome: a Case Report.

We report the case of a rare association between achalasia and Down syndrome in a child presenting with symptoms that suggest a gastroesophageal reflux. Evaluation of the patient with 24-hour multichannel intraluminal impedance and pH recording and upper endoscopy lead to the diagnosis of achalasia. However, the persistence of the symptoms after the concurrent surgical myomectomy and fundoplica...

Clinical Applications of Esophageal Multichannel Intraluminal Impedance Testing.

Multichannel intraluminal impedance is a relatively new technology that allows detection of bolus movement in the gastrointestinal tract without the use of radiation. In clinical applications it is combined with manometry, allowing a better evaluation of the functional characteristics (ie, bolus transit) of esophageal motility abnormalities. When combined with pH monitoring, it provides more co...

Principles of Combined Esophageal Impedance-ph Monitoring in Children: Indications, Benefits and Limitations

The standard test for suspected gastroesophageal refl ux is pH monitoring. However, the majority of gastroesophageal refl ux episodes in infants and children are nonacidic (pH > 4) and extraesophageal symptoms apparently can be caused by both acidic (pH < 4) and nonacidic refl ux. In order to overcome these aspects, a new technique has been developed and placed under scrutiny in the past twenty...
