However, esophageal manometry is usually not the first test used to diagnose these conditions.
Limitations
While manometry is useful in identifying motility problems, it does have its limitations.
This may lead to inconclusive or ambiguous results.

It is for this reason that expert consultation is needed if the findings are anything less than conclusive.
Occasionally, during insertion, the tube may enter the larynx (voice box) and cause choking.
Before the Test
An esophageal manometry does require some preparation on your part.
Timing
The test itself takes around 15 to 30 minutes to perform.
Barring delays, you should be in and out of the office within 60 to 90 minutes.
Esophageal manometry is often performed in the morning to ensure your stomach is empty.
It is best to arrive a half hour in advance to sign in and settle.
Location
Esophageal manometry is an in-office produce typically performed by agastroenterologist.
The catheter itself is equipped with eight sensors able to detect subtle changes in esophageal pressure.
What to Wear
It is best to wear a loose-fitting outfit.
If this instruction is not followed, the healthcare provider may have to cancel and reschedule your appointment.
Medications
There are a number of medications that can affect the motility of your esophagus.
Some need to be stopped to ensure they do not interfere with the testing.
These costs may be covered in part or in full by your health insurance.
The test requires insurance pre-authorization, which your gastroenterologist can submit on your behalf.
If approved, it is important to know what your co-pay and out-of-pocket expenses will be.
If you are denied coverage, ask your insurer for a written reason for the denial.
Your gastroenterologist should also intervene and provide additional motivation as needed.
Other Considerations
Sedatives are not used for an esophageal manometry test.
You would then be taken to an examination room.
Pre-Test
The esophageal manometry test is usually performed by a specially trained gastrointestinal (GI) motility nurse.
A nursing assistant may provide support.
Upon entering, you will be provided a hospital gown and asked to sit on an examination table.
Sedatives are not used because they can over-relax the esophagus and interfere with the test results.
A topical numbing agent may be used to help ease discomfort.
You will likely be given the choice of which nostril to use for the test.
(The nasal route is preferred as it is less likely to cause gagging than the throat.)
A GI motility nurse is highly trained in this procedure.
attempt to relax by slowing your breathing, relaxing your shoulders, and unclenching your fists.
If you feel any discomfort, let the nurse know without panicking.
you’ve got the option to resume your normal diet and any medications you regularly take.
The irritation will usually go away in a day or so.
It is also not uncommon to have blocked sinuses and minor nosebleeds.
Antihistamines don’t usually help since the swelling is due more to inflammation than allergy.
At times, the answers may not be so clear.
Esophageal manometry is a technically challenging test prone to variables that can sway the results.
Clinical experience and expertise are, therefore, central to obtaining an accurate diagnosis.
Sometimes it helps to be walked through the procedure and see what the catheter actually looks like.
Knowing what to expect can relieve a lot of the fear.
take a stab at focus on the benefits and aims of the test.
As a relatively fast and safe procedure, the benefits of esophageal manometry will almost always outweigh the downsides.
An esophageal diverticulum is a small pouch that can develop in weak areas of the esophageal lining.
The exact cause of esophageal spasms is unknown.
Some researchers believe it occurs due to faulty nerves that control the muscles of the esophagus.
Spasms may also be because of too much acid in the esophagus due to heartburn.
