Background: Laryngopharyngeal reflux (LPR) is a highly prevalent disease and commonly encountered in the otolaryngologist’s office. Study to evaluate the presentation of different signs and symptoms of LPR along with evaluating the role of empiric PPI (proton pump inhibitor) in the management of LPR by observing its effect on RFS and RSI.
Methods: A prospective observational study was conducted on 100 cases having different symptoms of LPR. Reflux symptom index (RSI) and Reflux finding score (RFS) were used to diagnose LPR. Patients were put on PPI (Pantoprazole 40 mg OD for 12 weeks) and followed up at 4,8 and 12 weeks and successive RSI and RFS scores were evaluated. The results were compiled and analyzed statistically.
Results: Among all symptoms, most common presenting symptom of LPR was foreign body/sensation of something sticking in throat (80%). Upon pharmacological therapy with PPIs (Pantoprazole), the mean RSI score changed from 22.94±5.83 to 11.19±2.97 at 12 weeks of PPI therapy. The mean RFS score changed from 12.93±3.55 to 6.86±2.86 at 12 weeks of PPI therapy. The change in the RFS and RSI score was highly significant (p=0.001).
Conclusions: LPR is a common condition presenting in ENT settings, the symptoms and signs of which may be complex. RFS and RSI score are valuable tools for diagnosing LPR. PPIs are proven to be effective therapy for LPR, more studies are encouraged to affirm the efficacy of PPIs over other management options.
