Diagnosis of LPRD with the Reflux Symptom Index and the Effect of Proton Pump Inhibitors

Abstract

We used the Reflux Symptom Index (RSI) for the diagnosis of laryngopharyngeal reflux disease (LPRD) with 38 patients. Eighteen patients had RSI scores >13. The remaining 20 patients had RSI scores ≤13. We used the Frequency Scale for Symptom of GERD (FSSG) for 20 patients. We prescribed proton pump inhibitors (PPI) for all 38 patients. The RSI score of 38patiens decreased statistically for 4weeks. That of 18 patients (RSI >13) also did for 4 weeks. The FSSG scores also decreased over the same period; however, there is not interrelation between the RSI and FSSG scores. Those findings suggest that RSI is useful for the diagnosis of LPRD.
