Gastroesophageal Reflux Clinical Trial
Official title:
Usefulness of Wireless pH Monitoring in the Diagnosis of Gastroesophageal Reflux Disease
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.
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. ;
