To study the relationship between laryngopharyngeal reflux (LPR) and gastroesophageal reflux disease (GERD) using clinical scoring and endoscopy. Data was collected from a sample of 100 patients with GERD symptoms who presented to ENT out-patient department, for a duration of 2 years. Patients were evaluated using Reflux Symptom Index (RSI) questionnaire and Reflux Finding Score (RFS). All patients underwent videolaryngoscopy and upper gastrointestinal endoscopy. Patient with positive findings underwent treatment with proton pump inhibitors and were followed up for 3 months. Out of 100 patients, 23 had LPR, 19 had GERD, 40 had LPR + GERD, 18 were normal. Among the LPR group, the predominant symptoms were hoarseness of voice, globus sensation and heartburn. Majority of GERD group had globus sensation, dysphagia and heartburn as their predominant symptoms. On laryngoscopy, in both LPR and LPR + GERD group, most common finding was interarytenoid erythema and vocal cord edema. On esophagogastroduodenoscopy, in both GERD and LPR + GERD group, esophagitis was the most common finding. RSI value was highest in patients with LPR + GERD. RFS value was high in LPR group followed by groups of LPR + GERD and GERD. RSI and RFS are easily administered, highly reproducible, low cost clinical scoring symptom questionnaire which can identify the patients with LPR. 82.6% of LPR patients had significant RFS scoring but with no significant findings in OGD. This study also illustrates the importance of PPI therapy in LPR patients with no evidence of GERD.
