[Preliminary application of Dx-pH monitoring system in laryngopharyngeal reflux disease].
Objective:To summarize the application and significance of Dx-pH monitoring system in laryngopharyngeal reflux disease.Methods:Fifty-four patients who had symptoms of laryngopharyngeal reflux disease in our department from February to December in 2015 were retrospectively analyzed in this study. All patients were evaluated with reflux symptoms index(RSI), flexible laryngoscope and reflux finding score(RFS), and larygopharygeal Dx-pH monitoring.Results:Among all 54 patients, there were 26 patients whose Ryan score were positive(48.2%). The positive Ryan score mainly emerged when the patients were upright(24/26, 92.3%). Among 22 patients whose symptoms could not alleviate well by 8 weeks proton pump inhibitors treatment, there were 13 patients(59.1%) with positive Ryan scores. The Ryan scores were not in good accordance with RSI and RFS(κ=-0.013).Conclusions:Although the results were not in good accordance with RSI/RFS, Dx-pH monitoring system could prove laryngopharyngeal reflux events in patients with laryngopharyngeal reflux disease and help physicians to diagnose.
