Thirty consecutive patients with GERD symptoms and an acid exposure time (AET) measured by impedance measurement/pH between 4 and 6% will be included.~A 96-hour off IBP wireless pH monitoring capsule will be performed. The worst day, the average of the 4 days and the presence of 2 or more days with AET>6% and the 4 days with AET<4% will be recorded.~Patients will be categorized into GERD, reflux hypersensitivity, and functional heartburn. A treatment will be established based on these categories and the GERDq will be measured at 8 weeks of treatment.
Gastroesophageal reflux disease (GERD) is extremely common in our environment. Its diagnosis is complex. The Lyon Consensus defined, based on 24-hour pH monitoring, that an acid exposure time greater than 6% is definitely abnormal, less than 4% is normal, and between 4 and 6% is a gray area.~The objective of this study is to describe the change in therapeutic behavior based on the result of prolonged pH recording performed with a 96-hour wireless pH measurement capsule in patients with GERD symptoms and an acid exposure time measured by impedanciometry/pH of 24 hours in the gray area. Also, describe the therapeutic outcomes.
