Abstract

Esophageal pH monitoring, which employs a pH electrode to detect acid reflux in the distal esophagus, was first introduced in 1969 (Br J Surg 56:912–914, 1969). Over the years, the advantages and limitations of traditional, catheter-based esophageal pH monitoring have become better defined, with a subsequent evolution of newer diagnostic techniques. Wireless methods to detect acidic contents in the esophagus have now become available (Bravo pH capsule). Additionally, we have seen the development of the technical capability of measuring both acid and nonacid reflux with multichannel intraluminal impedance. In the present chapter, we will discuss the technical details, clinical indications, and applications of these diagnostic techniques for the dynamic detection of reflux episodes.
