what kind of test is an esophageal motility test
Esophageal manometry is a diagnostic test that uses tiny transducers or receivers that are integrated into a thin catheter or tube that is inserted into the esophagus to measure pressure. This device is used to measure the LES length and resting pressure, its ability to relax with swallowing, the contractile strength and coordination of the esophageal body, and the upper esophageal sphincter characteristics.
