Role of Reflux Symptom Index and Reflux Finding Score in Diagnosing Laryngopharyngeal Reflux: A Prospective Study


Laryngopharyngeal Reflux Disease (LPRD) is caused due to reflux of gastric content into the larynx and pharynx. The present study was done to assess the role of Reflux Symptom Index (RSI) and Reflux Finding Score (RFS) in the treatment outcomes in symptomatic patients with LPRD. This is a prospective analytical study conducted on 200 patients for a period of 2 years, from January 2020 to February 2022. Patients suspected with LPR were evaluated using RSI and RFS, and both pre and post treatment scores were compared to assess the change in scores of RSI and RFS following 8 weeks of treatment with PPI (Proton pump inhibitor). The patients experienced a greater incidence of moderate symptoms in RSI. Wilcoxon signed-rank test showed significant difference between pre and post treatment scores with respect to reflux symptoms and reflux findings (p < 0.05). Implementation of RSI and RFS scoring system helped for early diagnosis of LPR, and a significant difference was seen between pre and post treatment scores in both RSI and RFS.
