Abstract

TORO-MONJARAZ, Erick Manuel et al. Esophageal impedance monitoring for the diagnosis of gastroesophageal reflux disease in children. Acta pediatr. Méx [online]. 2015, vol.36, n.1, pp.43-49. ISSN 2395-8235.

Gastroesophageal reflux is defined as the presence of gastric content towards the esophagus, and the gastroesophageal reflux disease is when it manifests with signs and symptoms. pH monitoring remains the primary diagnostic tool for detecting gastroesophageal reflux, but new technology has been developed to support this diagnose. The impedance-pH monitoring is based in the changes of the electric impedance at the gastrointestinal lumen given by the passing of the bolus (air, food, saliva, gastroduodenal content). With this study, we can evaluate the movement pattern antegrade or retrograde, bolus presence time, direction and velocity of bolus movement within the esophagus and detect any acid or non acid event. The objective of this revision is to evaluate this method in children, technique, indications and benefits of the impedance-pH monitoring.

Keywords : Gastroesophageal reflux; gastroesophageal reflux disease; impedance monitoring; acid gastroesophageal reflux; nonacid gastroesophageal reflux.
