Devices for Esophageal Function Testing

Esophageal symptoms are commonly encountered in clinical practice from a variety of conditions including GERD, motility abnormalities, functional disorders, structural anomalies, and behavioral conditions. Esophageal function testing has become an integral component for evaluation of selected individuals with these disorders. This technology document provides an overview of the current esophageal function technologies including functional luminal imaging probe (FLIP), high-resolution esophageal manometry (HRM), and multichannel intraluminal impedance (MII) and pH monitoring.
