ABSTRACT
OBJECTIVE: Globus pharyngeus (GP) is a common symptom of laryngopharyngeal reflux disease (LPRD), and proton pump inhibitor (PPI) and rikkunshito, a traditional Japanese medicine having prokinetic effect improve LPRD symptoms. In the present study, we examined the efficacy of high-dose PPI in combination with rikkunshito in patients complaining of GP. METHODS: 106 patients complaining of GP without any organic endoscopic findings were enrolled. RESULTS: Patients were first administrated with high-dose PPI alone for 4 to 8 weeks and the symptom was improved in 65 patients. Among 41 patients with PPI-refractory GP, 22 patients were administrated with high-dose PPI in combination with rikkunshito, and the symptom was improved in 14 of 22 patients 4 weeks later. The average value of a modified reflux symptom index of the responders was similar to that of non-responders. Only a few patients had positive values in reflux finding scores in both groups. CONCLUSION: The present findings suggest the existence of a high prevalence of LPRD in patients complaining of GP. The data also suggest that gastroesophageal dysmotility is involved in GP, in addition to excessive acid reflux. The pre-therapeutic laryngopharyngeal symptoms and endoscopic findings could not predict the efficacy of the treatment for GP. J. Med. Invest. 63: 227-229, August, 2016.
