Abstract
Oesophageal manometry and prolonged ambulatory pH monitoring were performed in 47 patients with the globus sensation, 48 control subjects and 28 patients with documented oesophagitis. Globus patients also underwent video-recorded barium examination and rigid endoscopy. Manometry was normal in 38 of the globus group (94%). The mean percentage time below pH 4 was 4.16 in controls, 5.11 in globus patients (NS) and 18.54 in oesophagitis patients (P less than 0.0005). Oesophageal acid exposure did not correlate with sex, smoking or heartburn and correlated with age only in oesophagitis patients (P less than 0.001). Biopsy showed mild laryngitis in 2 globus patients and distal oesophagitis in 6 (13%). Abnormal oesophageal acid exposure and distal oesophageal dysmotility are not aetiological factors in the majority of patients with globus pharyngis.
