Emory University Study on Restech Airway pH Probe Shows Promising Outlook for Innovative Test
SAN DIEGO, CA -- 05/11/2007 -- Laryngopharyngeal reflux (LPR) was
among the most discussed issues at April's worldwide Combined Otolaryngology
Spring Meeting (COSM) in San Diego. The only medical device designed
to detect LPR, the Restech Dx-pH Measurement System™ was
featured in a comparative study presented during a poster session
of the American Bronchoesophagological Association (ABEA) by the
Emory University Voice Center.
Justin Golub, M.D., Michael Johns, III, M.D., John DelGaudio, M.D.,
and Adam Klein, M.D. displayed the poster "Preliminary Comparison
of an Oropharyngeal pH Probe and a Traditional Dual Channel Probe
for Diagnosis of Laryngopharyngeal Reflux."
Dr. Golub presented the preliminary study findings and answered
questions at COSM on Friday, April 27, posed by Otolaryngologists
from around the world. The head of Emory's Voice Center, Dr. Michael
Johns, III, summarized his experience with the device and the preliminary
outcome of the study:
"Initial data using the oropharyngeal pH probe are promising.
There was a high correlation to acid reflux events above the upper
esophageal sphincter as measured by a traditional probe, and patient
comfort and tolerance were much higher."
The study commenced in early 2006 after Emory researchers were
granted funds from AstraZeneca through their Investigator Initiated
Research program. The overall study will include sixty-five patients
whose laryngopharyngeal reflux activity will be monitored with
the Dx-System for a period of twenty-four hours. Through this study,
the researchers hope to further establish the value of the Dx-pH
Measurement System as a diagnostic modality for LPR.
Restech's Dx-pH Measurement System is a promising device for Otolaryngology
practice due to the absence of a specific test for LPR. While current
technology has been useful for diagnosing esophageal reflux, it
is incapable of measuring aerosolized supraesophageal reflux, which
can have deleterious effects on the very sensitive laryngeal tissue.
