High-resolution esophageal manometry: Principles, technique, and interpretation

Abstract

There are many upper and lower gastrointestinal (GI) disorders in which either the cause or the result is abnormal motility. Naturally, the study of motor functions of the gut in normal and abnormal conditions is of great help in understanding the pathophysiology and management of these disorders. Motor functions of the GI tract can be assessed by a variety of recording techniques including radiology, scintigraphy, manometry, and most recently intraluminal electrical impedance monitoring. In many instances the techniques are complementary to each other. However, manometry is the most reliable and reproducible method of studying motor functions of the esophagus. In this chapter we will elaborate principles, technique, and interpretation of esophageal manometry.
