About Your Esophageal Manometry

This information will help you get ready for your esophageal manometry procedure at Memorial Sloan Kettering (MSK).

Esophageal manometry measures the function of your esophagus (food pipe). It’s done to find out why you have symptoms such as difficulty or pain when you swallow or chest pain. It’s also done before anti-reflux surgery. You don’t need anesthesia (medication to make you fall asleep) for this procedure.

Where to park

MSK’s parking garage is located on East 66th Street between York and First Avenues. If you have questions about prices, call 212-639-2338.

To reach the garage, turn onto East 66th Street from York Avenue. The garage is located about a quarter of a block in from York Avenue, on the right-hand (north) side of the street. There is a pedestrian tunnel that you can walk through that connects the garage to the hospital.

There are also other garages located on East 69th Street between First and Second Avenues, East 67th Street between York and First Avenues, and East 65th Street between First and Second Avenues.

Where to go

Your procedure will take place in the Endoscopy Unit. It’s located in Memorial Hospital (MSK’s main hospital). The address is:

1275 York Avenue (between East 67th and East 68th Streets)
New York, NY 10065

Once you arrive at Memorial Hospital, take the M elevator to the 2nd floor.

What to expect

Once you arrive at the hospital, doctors, nurses, and other staff members will ask you to say and spell your name and date of birth many times. This is for your safety. People with the same or a similar name might be having a procedure on the same day.

Your doctor will explain the procedure to you and answer your questions. They will ask you to sign a consent form.

When it’s time for your procedure, you will be brought into the room where it will be done. An anesthetic (numbing) gel will be put in your nose with a cotton swab (Q-tip®). Once your nose is numb, your doctor will pass a thin tube through your nose and into your stomach. You might have some mild gagging or discomfort, but these feelings will go away quickly.

When the tube is in place, your doctor will ask you to swallow small sips of water. The pressure of the muscle contractions that happen after you swallow will be measured along several sections of your esophagus. The tube will be removed after the procedure is completed.

The procedure takes about 15 minutes.
