The role of hypervigilance in chronic esophageal diseases: a scoping review.

Background: Hypervigilance has emerged as an important construct in esophageal symptom reporting, but a review of the literature does not currently exist. This scoping review aimed to generate a comprehensive overview of the literature on hypervigilance in esophageal diseases and summarize the evidence for each esophageal disease. Methods: Guided by the Joanna Briggs Institute scoping review methodology, articles that were peer-reviewed original studies, published in English, and included adult patients with at least one esophageal disease were included. Articles were retrieved from PubMed and Embase databases and screened first by title and abstract for an initial round of exclusions, and then again by full text for a second round of exclusions. Results: Nineteen studies were included. Studies were categorized by primary diagnosis: achalasia (1, 5%), eosinophilic esophagitis (1, 5%), gastroesophageal reflux disease (GERD) (6, 32%), laryngopharyngeal reflux (3, 16%), non-cardiac chest pain (3, 16%), and multi-disorder samples (5, 26%). Studies primarily evaluated associations between hypervigilance and symptom severity, psychosocial functioning, health-related quality of life, and physiological disease variables. A number of studies also evaluated hypervigilance across esophageal diseases or presentations (e.g., across motility disorders, across GERD phenotypes). Conclusions: The role of hypervigilance in symptom reporting has been investigated in multiple esophageal conditions. Findings suggest potential clinical utility in assessing hypervigilance, such as for disease conceptualization and treatment planning. Future research is needed in larger samples, with consistent measures of hypervigilance, and using data synthesis methodology (i.e., systematic reviews) to better compare and contrast findings across studies.
