Background and Objectives:A 24-hour ambulatory dual probe for pH monitoring is the most specific and sensitive test for laryngopharyngeal reflux (LPR) disease. However, the use of this probe is not well tolerated in some patients due to discomfort and the invasive nature of the procedure. Thus, the diagnosis of LPR is usually made according to symptomatic responses to empirical treatment using a proton-pump inhibitor for patients with high score of reflux symptom index (RSI) and reflux finding score (RFS). The aim of this study is to evaluate the relationship between the RSI and RFS and pH monitoring using a 24-hour ambulatory dual probe, and determine the role of RSI and RFS in the diagnosis of LPR.
Subjects and Method:We studied 100 patients who underwent pH monitoring using a 24-hour dual probe because of laryngopharyngeal reflux related symptoms or laryngoscopic findings. The various parameters of the 24-hour dual probe pH monitoring were compared with the scores of RSI and RFS.
Results:In 24-hour dual probe pH monitoring, 64 of 100 patients tested positive for LPR. The mean of RSI score was significantly higher in the positive LPR group than in the negative group. However, RFS did not differ between the two groups. RSI scores were significantly associated with the reflux number in the upright position of the 24-hour dual probe pH monitoring. There was no correlation between RFS and the parameters of the 24-hour dual probe pH monitoring.
Conclusion:RSI can be a reliable diagnostic tool for laryngopharyngeal reflux disease instead of the 24-hour ambulatory dual probe pH monitoring.
