Esophageal Manometry

Esophageal manometry is a test used to examine the esophagus of patients with symptoms of heartburn, difficulty swallowing, asthma and chest or stomach pain. There are two types of manometry testing. The type of manometry needed will be determined by your ordering physician.

Standard manometry is a test used to examine the motor or muscle function of the esophagus (swallowing tube) and determines the effectiveness of the valve between the esophagus and the stomach. Before inserting the tube, the nose is anesthetized to make this procedure more comfortable. You will not be sedated for this test as sedation will affect the pressures in the esophagus. The test consists of pulling the tube back very slowly through the esophagus and also performing swallows with water.

Impedance manometry allows the assessment of esophageal pressures like the standard manometry but also assesses esophageal function of bolus movement. Before inserting the tube, the nose is anesthetized to make this procedure more comfortable. You will not be sedated for this test as sedation will affect the pressures in the esophagus. The test consists of passing the tube into the esophagus. A series of swallows with normal saline and viscous swallows with applesauce are performed.

Your physician will prescribe the necessary preparation for this procedure.
