Abstract
BACKGROUND: The association between laryngopharyngeal reflux (LPR) and abnormalities of upper esophageal sphincter (UES) and esophageal motility is not clearly known. High-resolution esophageal manometry (HREM) has allowed accurate measurement and evaluation of UES and esophageal function. GOALS: To evaluate the UES function and esophageal motility using HREM in patients with LPR and compare them to patients with typical gastroesophageal reflux disease (GERD). STUDY: All patients evaluated for GERD or LPR symptoms with esophageal function testing including HREM, ambulatory distal pH monitoring and upper endoscopy between 2006 and 2014 were retrospectively studied (n = 220). The study group (group A, n = 57) consisted of patients diagnosed with LPR after comprehensive evaluation. They were compared to patients who had typical GERD symptoms only (group B, n = 98) and patients with both GERD and LPR symptoms (group C, n = 65). RESULTS: Abnormalities in UES pressures and relaxation were found in about one-third of patients in all groups. There were no significant differences between the groups. Group B had higher prevalence of abnormal esophageal motility compared to others (group A vs. B vs. C = 20.8% vs. 28% vs. 12.5%, p = .029). Group B patients also had higher prevalence of Barrett's esophagus compared to others (group A vs. B vs. C = 0% vs.12.2% vs. 4.6%, p = .01). Distal pH testing revealed no significant differences between the three groups. CONCLUSIONS: Abnormal UES function was noted in one-third of patients with LPR or GERD. However, there were no abnormalities on esophageal function testing specific for LPR.
