Limited diagnostic value of laryngopharyngeal lesions in patients with gastroesophageal reflux during routine upper gastrointestinal endoscopy.

Background And Aims: There is growing evidence that gastroesophageal reflux disease (GERD) may cause typical laryngeal/pharyngeal lesions secondary to tissue irritation. The prevalence of those lesions in GERD patients is not well established. The aim of this study was to evaluate the prevalence of GERD signs in the laryngopharyngeal area during routine upper gastrointestinal endoscopy.
