Abstract
To determine the advantages and effectiveness of modern methods for diagnosing extraesophageal manifestations of GERD in relation to the classical ones. Methodology. This paper presents a literature review from Pubmed, Web of Science, Willey Online Library and Google Scholar sources over the past 10 years on the diagnosis of extraesophageal manifestations of GERD. We selected 73 articles on the epidemiology and diagnosis of GERD, of which 13 were on a new oropharyngeal pH probe (Restech). Based on the literature sources studied by us, we analyzed the effectiveness and accuracy of a new method for diagnosing extraesophageal manifestations of GERD by the pharyngeal probe test (Restech) in comparison with more classical research methods – a symptom questionnaire, a scale of clinical manifestations, a test with proton pump inhibitors and 24-hour pH probe testing of the esophagus.
