Research output: Contribution to journalArticlepeer-review


The following paper on functional testing of the pharynx includes commentaries on the use of 24-h pH-impedance testing to identify patients with nonacid reflux and the caveats associated with automatic and visual analysis; the potential diagnostic yield of ambulatory high-resolution manomentry (HRM), particularly in identifying non-cardiac chest pain and transient lower esophageal sphincter relaxations; the differential manometric identification of conditions facilitated by using solid swallows, and the advantages of the newly developed ResTech oropharyngeal pH probe in the detection of proximal reflux events.
