Correlation between reflux symptoms score -12 and reflux finding score
in patients with laryngopharyngeal reflux symptoms
Abstract
Background and aim: The reflux symptoms score -12 (RSS-12) is a
validated questionnaire with good sensitivity and specificity for
diagnosing laryngopharyngeal reflux disease (LPRD). However, the
correlation between RSS-12 and reflux finding score (RFS) in patients
with clinical symptoms suggestive of LPR has not been investigated. In
this study, we examined such correlation. Patients and methods:
We conducted cohort cross sectional study over 6 months duration in
total of 105 patients with typical gastroesophageal reflux disease (GERD
) symptoms associated with LPR symptoms based on RSS-12.We excluded
patients with any medical problems or lifestyle habits that could induce
similar symptoms. The study participants underwent a telescopic
laryngeal examination and the RFS was calculated. Results: The
prevalence of LPRD (RFS > 7) in patients with clinical
symptoms of GERD and LPR was 14.2% (15 patients). Laryngoscopic
abnormalities unrelated to LPRD were present in 16 patients (15.2%).
RSS-12 had strong positive correlation with RFS. Conclusion: In
patients with clinical symptoms of LPR, RSS-12 strongly predicts the
diagnosis of LPRD.
