NCT ID: NCT01854970 Completed - Clinical trials for Laryngopharyngeal Reflux

Benefit of Pharyngeal and Oesophageal pH-impedance of Patients With High Suspicion of Laryngopharyngeal Reflux

PHARO
Start date: May 2013
Phase: N/A
Study type: Interventional

Laryngopharyngeal reflux (LPR) is the retrograde movement of gastric contents into the larynx, pharynx and upper aerodigestive tract. The symptoms and manifestations are very changeable and non specific. Pharyngeal and Oesophageal pH-impedance may help to detect these reflux and to identify patients with abnormal LPR. To compare and describe the results of pharyngeal and oesophageal pH-impedance of patients with high suspicion of laryngopharyngeal reflux, with the results of healthy patients.
