Esophageal Manometrics (Esophageal MANO)

What is the Esophageal Manometrics test?

This test examines the movement and pressures of your esophagus. This test will involve the placement of a tube through your nasal passage, or nostril, and then swallowed into your esophagus with drinks of water.

What will happen during the test?

You will be able to swallow, talk, and breathe without any difficulty during the test. We will record the movement and pressures of your esophagus as you drink small amounts of water. Acid testing will be done to document any acid coming from your stomach into your esophagus.

What are the instructions prior to the test?

This test will take between 1 to 2 hours to run. You should not eat or drink after midnight the night before your test when scheduled for a morning appointment. If scheduled for an afternoon appointment, you may have clear liquids until 9 a.m. on the day of your exam, then nothing by mouth after that time. Do not take any oral medications on the day of the exam. Please notify the nurse if you have diabetes and take insulin.

Where is the test performed?

This test will be run in the GI Physiology and Manometry Laboratory in the Medical Procedures Unit, located at University Hospital level 2B353.

If you are unable to keep your appointment or if you have questions regarding the test or medications, please call the GI Physiology Lab in the MPU at (734) 936-9250, option 2.
