title: Reflux monitoring: current status.
abstract: Gastroesophageal reflux monitoring is a key investigation in managing gastroesophageal reflux disease. Esophageal pH monitoring is used to quantify esophageal acid exposure and the association of symptoms with acidic reflux episodes. Recently available wireless pH monitoring systems allow reflux monitoring over prolonged periods and increase patient comfort during the procedure. Combined impedance-pH monitoring offers the ability to identify reflux episodes independently of their acid content, an important advantage when evaluating patients with symptoms persisting during acid-suppressive therapy.
