Esophageal manometry

An esophageal manometry test is designed to check the motility (movement capabilities) of the esophagus and the function of the esophagus’s upper and lower sphincter muscles (that open and close, controlling the flow of acid and bodily fluids).

The clinician performing the test inserts a thin, flexible catheter (tube) containing a monitor through the nostril into the esophagus. The monitor measures the pressure in the esophagus, and assesses if the patient is experiencing motility problems that may be causing various symptoms.

Anorectal manometry

Anorectal manometry assesses the pressure and function of the anal sphincter (muscle that opens and closes) and rectum.

The clinician performs the test by inserting a thin, flexible tube (catheter) with a small balloon at its tip into the anus. Rectal sphincter pressure is measured in various states of contraction and relaxation, and the sensation in the anus and muscle synchronization are also checked.
