Summary
Purpose
To evaluate the differences in diagnostic rates according to the age and sex of patients
with suspected laryngopharyngeal reflux (LPR) symptoms and completed the 24-hour hypopharyngeal-esophageal
multichannel intraluminal impedance-pH (24h-HEMII-pH) monitoring.
Methods
Patients with LPR symptoms underwent the 24h-HEMII-pH monitoring. We compared the
diagnostic rates of LPR in patients with LPR symptoms according to age and sex. The
number of reflux episodes and type of reflux were compared among patients who were
confirmed to have LPR according to age and sex.
Results
A total of 249 patients with suspected LPR symptoms who completed 24h-HEMII-pH monitoring
were analyzed. A total of 170 patients (68.3%) were diagnosed with LPR after 24h-HEMII-pH
monitoring. There were 57 (67.1%) men and 113 (68.9%) women. The old age group (older
than 55 years) showed a statistically significant higher diagnostic rate than the
young age group (73.5%, 60.8%, p=0.034). Women's diagnostic rate was statistically
higher in the old age group than that in the young age group (75% vs. 58.3%, p=0.026).
There were no specific differences in the number of refluxes in the diagnosed patients
between the age groups, and there were no differences in the initial reflux symptom
index.
Conclusions
Among those who visited the clinic with suspected LPR symptoms and performed 24h-HEMII-pH
monitoring, the diagnostic rate of LPR was higher in the older age group than that
in the younger age group.
