Gastroesophageal reflux disease (GERD) is defined as the abnormal transit of gastric contents into the esophagus. It is caused by an alteration of the anti-reflux barrier, causing multiple symptoms or complications. In order to achieve accurate diagnosis and proper therapeutic approach, integration of clinical findings, endoscopic findings and 24-hour esophageal pH monitoring, with or without impedancometry, is required. These tests must be performed following technical specifications and their interpretation must be based on the best clinical evidence available to obtain accurate diagnoses that allow making the best decisions to the benefit of patients.

Recently, the Lyon Consensus incorporated new guidelines for the diagnosis of GERD by esophageal pH monitoring, which are reviewed in this paper.

Keywords : pH-impedance monitoring; Gastroesophageal reflux disease; Proton-pump inhibitor.
