[Advantages of pH-impedance monitoring in gastroesophageal reflux and dysphagia investigations].
ENT symptoms of gastro-esophageal reflux are frequent. pH-impedance can detect acid and non-acid reflux and measure their proximal extension. The technique identifies the refluxate by changes in impedance. We discuss 2 clinical situations where correlation of symptoms could be explained by a non-acid reflux in the first case, and a lack of acid suppression in the second case, respectively. These results lead to a specific additional treatment to proton pump inhibitors (PPI). This technology provides a better understanding of the pathogenesis of reflux laryngitis, and affords the prescription of PPI on a proven diagnosis. Detection of non-acid reflux leads to an optimized medical treatment.
