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.
