Swallowing Disorders Read more. Sedatives are not used for an esophageal manometry test. As a result, you can usually drive yourself to and from the healthcare provider's office without concern.
On the day of your test, after signing in and confirming your insurance information, you may be asked to sign a liability form stating that you understand the purpose and risks of the test. You would then be taken to an examination room.
The esophageal manometry test is usually performed by a specially trained gastrointestinal GI motility nurse. Either a doctor or a GI registered nurse certified by the Society of Gastroenterology Nurses and Associates or other certifying bodies is qualified to oversee the procedure. A nursing assistant may provide support. Upon entering, you will be provided a hospital gown and asked to sit on an examination table. You will need to remove your glasses and anything in your mouth that could be dislodged, such as a tongue piercing.
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. Try to relax by slowing your breathing, relaxing your shoulders, and unclenching your fists.
If you feel any discomfort, let the nurse know without panicking. Throughout the Test. An esophageal manometry test can vary by the type of equipment used but more or less follows the same basic steps:.
Once completed, you will be given a tissue to blow your nose but otherwise will be well enough to return home. You can resume your normal diet and any medications you regularly take. Side effects of esophageal manometry tend to be minor and may include a mild sore throat, coughing, minor nosebleeds, and sinus irritation. If your throat is sore following an esophageal manometry test, you can either gargle with salt water or use a benzocaine throat lozenge like Cepacol.
The irritation will usually go away in a day or so. It is also not uncommon to have blocked sinuses and minor nosebleeds. You can often help clear sinuses with an over-the-counter corticosteroid nasal spray or a sterile saline nasal spray. Antihistamines don't usually help since the swelling is due more to inflammation than allergy.
Nosebleeds can be treated by pinching the soft part of your nose above the nostril, leaning forward, and breathing through your mouth.
While serious side effects are uncommon, you should call your healthcare provider immediately if you experience any unusual symptoms, including fever, severe reflux, vomiting, arrhythmia, shortness of breath, or bloody sputum.
A few days after the test is performed, your healthcare provider will review the results with you. While the tests can provide valuable insights into how well your esophagus and sphincters are functioning, clinical judgment may be needed to interpret the results. At times, the answers may not be so clear. Esophageal manometry is a technically challenging test prone to variables that can sway the results. While the tests may provide irrefutable evidence of a motility problem such as dysphagia , other conditions like achalasia may be far more difficult to pin down.
Clinical experience and expertise are, therefore, central to obtaining an accurate diagnosis. If you are not fully convinced of what is being told you, do not hesitate to seek a second opinion. Sometimes a fresh set of eyes can add new insights and bring you that much closer to an effective treatment. If you are feeling nervous about undergoing an esophageal manometry, don't wait until last minute to share these concerns with your healthcare provider or a member of the medical staff.
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. Try to 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.
