Background: The role of gastropharyngeal reflux in patients with globus pharyngeus and hoarseness remains unclear.
Objective: To evaluate patients with complaints of globus, hoarseness, or globus and hoarseness combined for the presence of gastropharyngeal and gastroesophageal reflux.
Design: Prospective clinical cohort study of 3 groups of patients undergoing ambulatory 24-hour double-probe pH monitoring. In patients with pathologic gastroesophageal reflux, an upper gastrointestinal endoscopy was also performed.
Setting: Tertiary care, outpatient clinic.
Patients: Twenty-seven patients with globus alone, 20 patients with hoarseness alone, and 25 patients with globus and hoarseness combined.
Results: Patients with well-defined pathologic reflux (ie, gastroesophageal reflux with or without gastropharyngeal reflux) were present mainly in the group of patients with globus combined with hoarseness: 18 (72%) of 25 patients, compared with 7 (35%) of 20 patients with hoarseness alone and 8 (30%) of 27 with globus alone. Seven (10%) of all 72 patients had prolonged acid exposure at the laryngopharyngeal junction in the presence of a normal gastroesophageal pH registration. Abnormal findings in the esophagus were found at endoscopy in 17 (65%) of 26 patients with pathologic gastroesophageal reflux (with or without gastropharyngeal reflux).
Conclusions: We found a high prevalence of pathologic reflux in patients with both globus and hoarseness. Based on these findings, we strongly advise upper gastrointestinal endoscopy for symptomatic otolaryngological patients with pathologic gastroesophageal reflux.
