Summary
Although laryno-pharyngeal reflux (LPR) and gastroesophageal reflux disease (GERD) differ in
symptoms and treatment, they are diagnosed by the same standard 24-hour pH monitoring system
which measures liquid reflux in the esophagus. The investigators are evaluating a new 24-hour
pharyngeal pH monitoring system by Restech which can measure acid exposure in the airway and
can be used specifically for LPR diagnosis. The purpose of this study is to determine whether
the Restech device is more effective than standard pH monitoring in predicting the response
to proton pump inhibitor (PPI) acid suppression therapy using Dexlansoprazole in patients
with symptoms and/or manifestations of LPR.
