Esophogeal Motility System
|
|
Description:
An Esophogeal Motility System is used to
measure pH levels during swallowing,
continually throughout the length of the
esophogus, and so indicates if there is a
specific section of the esophagus where
motility (i.e. movement of swallowed
material) is hindered. The standard
technique at the time was to force a probe
through the nasal cavity to reach the
esophogus. Dr. Richard Jones developed
a system which required the patient to
swallow a thin probe, a significant
improvement for the comfort of the patient.
