Introduction
Hypopharyngeal multichannel intraluminal impedance pH monitoring
(HEMII-pH) with nasopharyngeal catheter placement is the standard of
care for the diagnosis of gastroesophageal reflux disease (GERD) or
laryngopharyngeal reflux (LPR) [1,2]. The approach is safe but may
be awkward for patients. In a previous study, 61% of patients reported
that the test bothered them most of the time, although 69% said that
they would repeat the test if needed [3]. The placement of the
HEMII-pH probe is made in-office and may be realized by both
gastroenterologist and otolaryngologist. To date, a little number of
studies reported complications of the procedure, which consisted of
pain, discomfort or nose bleeding.
The aim of this paper is to report two unusual complications of
HEMII-pH.
