Patients above 18 years old with chronic esophageal disorders, that require a functional esophageal test such as ph-impedanciometry and/or high-resolution manometry, will be included. Written informed consent will be obtained. All participants will complete the questionnaire before performing the functional esophageal tests and a gastroenterologist specialized on functional esophageal pathology will perform the esophageal tests and analyze the results. Finally, the data from the questionnaire will be compared with the esophageal tests results in order to stablish if there is a correlation between the impact in the quality of life measured by the questionnaire and the tests results.
