Objective: To find a better screening test by correlating between history and video-laryngoscopy in patients with laryngopharyngeal reflux disease. To compare the Reflux Symptom Index (RSI) and the Reflux Finding Score (RFS).
Method: Patients with the signs and symptoms of LPRD were scored based on RSI. Those with RSI above 13 were included in study and evaluated further by videolaryngoscopy examination and rated according to RFS. The correlation between RSI and RFS was analysed.
Result: Out of the 107 patients included in study 55% were females. Among these patients positive RFS score (i.e. > 7) was seen in 58.3%. The average RSI was 18.22, and average RFS was 7.45. According to RSI the most common symptom was heartburn/indigestion (44.5%) and from RFS the most common finding was posterior commissure hypertrophy (95%). Correlation between RSI and total RFS was found to be 0.184 with a p value of 0.159 which was not significant.
Conclusion: LPRD is more common in females and in the middle age group. A correlation of RSI and RFS was not found to be significant suggesting that both should be used for diagnosis of LPRD instead of relying on only one. RFS and RSI are easy, quick and out patient based screening tools and when used together can be more reliable for LPRD diagnosis.
