Abstract:
Objective:The aim of this study is to determine the accuracy of RSI and RFS in the diagnosis of hypopharyngeal reflux （LPR）, the scores of RSI and RFS were compared in different age groups. To explore the RSI and RFS scoring thresholds for diagnosis of LPR in different age groups.
Method:From January 2017 to March 2019, 258 patients with suspected LPR in our hospital outpatient clinic completed the RSI and RFS scales. According to their age, 258 patients with RSI>13 and RFS>7 were selected. They were divided into group A （18-<40 years, n=86）, group B （40-<60 years, n=107） and group C （≥60 years, n=65）. The diagnosis was confirmed by 24 h pH-metry. The diagnostic rate, RSI and RFS scores were compared among the three groups. ROC curve was used to analyze the optimal thresholds for the diagnosis of LPR by RSI and RFS scores.
Result:Among the three groups, group C had the highest diagnostic rate（93.85%）. There was no significant difference in RFS score among the three groups （P>0.05）, RSI score was significantly different （P<0.05）, RSI score of group A and group B was higher than that of group C （P<0.05）. According to ROC analysis, the best RSI cutoffs for diagnosing LPR in group C was 11, and the area under the ROC curve was 0.866.
Conclusion:The RSI score is a good criterion for the diagnosis of LPR. The diagnostic threshold of RSI in elderly patients is different from that in young patients. For elderly patients, the diagnostic threshold for the recommended RSI score is 11.
