Esophageal manometry is a test that determines how well a person’s esophagus is functioning. An esophagus is a muscular, lengthy tube that links the throat to the stomach.
Esophagus contracts when one swallows, forcing food into the stomach. The contractions are measured by esophageal manometry. The esophageal muscles’ strength and coordination as they transport food to your stomach are also measured by the test.
During the procedure, a catheter (a thin, flexible tube) that contains pressure sensors is passed through the patient’s nose, down the esophagus, and into the stomach. The test can be useful in identifying some esophageal diseases.
Ideal Candidate for Esophageal Manometry Test
The manometry test is commonly used for people who have:
Possible Risks of Esophageal Manometry Test
Esophageal manometry is often painless and rarely causes difficulties. However, one might experience some discomfort while having the test, such as:
An individual could experience minor adverse effects following esophageal manometry, but these usually go away within a few hours. Included among the side effects are:
Preparation for the Esophageal Manometry Test
One might need to avoid eating and drinking for a given time before the test. The doctor will issue specific instructions. The patient needs to inform the doctor about the medication he/she is currently taking. The patient might be asked not to take some medications before the procedure.
What to Expect
High-resolution manometry can be used to measure the esophagus. In comparison to traditional manometry, high-resolution manometry employs more pressure sensors and is more accurate at determining pressure changes.
Without sedation, this test is performed as an outpatient procedure. Most people tolerate it well. Before the test begins, the patient might be requested to change into a hospital gown.
During the Procedure
The esophageal manometry test usually lasts about 30 minutes
Expected Results After Esophageal Manometry
In one to two days, the doctor will get the results of the patient’s esophageal manometry. The test results can aid in determining the cause of esophageal symptoms or be used as part of a preoperative evaluation.
Esophageal manometry is a diagnostic test used to evaluate the function and movement of the esophagus (the muscular tube connecting the throat to the stomach) and the lower esophageal sphincter (LES). It measures the pressure and coordination of muscle contractions in the esophagus during swallowing and at rest.
During an esophageal manometry test, a thin, flexible tube with pressure sensors called a manometry catheter is passed through the nose and into the esophagus. The catheter is connected to a computer system that records the pressure changes in the esophagus as you swallow. You will be asked to swallow saliva, water, or small amounts of a special liquid to stimulate the esophageal contractions while the sensors measure the pressure.
The duration of an esophageal manometry test typically ranges from 30 minutes to an hour, depending on the specific protocol and individual factors. The actual time for catheter insertion, testing, and removal is usually shorter, while additional time is allocated for preparation and instructions.
It is important to discuss your medications with your healthcare provider before the test. In general, you may be asked to avoid certain medications, such as antacids, muscle relaxants, and medications that affect the esophageal motility, for a specified time before the test. However, it is crucial to follow your healthcare provider's instructions regarding medication use.
