The concept of extraesophageal manifestations sec­ ondary to gastroesophageal reflux disease (GERD) is complex and not always clear. Although several extra­ esophageal symptoms have been associated with GERD, only asthma, cough, and hoarseness have evidence­based support [1]. The role of upper gastrointestinal endoscopy (UGIE) in GERD is that of screening in certain high­risk groups in particular overweight white males with chronic GERD symptoms and aged > 50 years [2]. In the context of suspected extraesophageal manifestations of GERD, UGIE has a low diagnostic yield and therefore poor pre­ dictive value for determination of GERD as the cause of these symptoms [1]. However, despite the foregoing, UGIE is still frequently requested and little is known about endoscopic findings in this context. In this issue of GE Portuguese Journal of Gastroenterology, Zullo et al. [3] present us the first study with data on the prevalence of relevant gastroesophageal lesions in pa­ tients with extraesophageal GERD manifestations. The authors concluded that clinically relevant lesions namely Barrett’s esophagus, erosive esophagitis, and hiatal hernia are uncommon among young (< 50 years) patients with only extraesophageal GERD manifestations, and the use­ fulness of UGIE in these patients is questionable. One of the major factors that contributes to the con­ troversy of GERD­associated extraesophageal manifesta­ tions is that other potential causes have not been ade­ quately evaluated and/or treated before [4]. In Zullo et al. [3], UGIE was prescribed by different specialists and nothing was told about other previous tests done in inves­ tigation and its results. Additionally, the specificities about present or past proton pump inhibitors therapy (dosage, duration, response) have not been given. On the
