Esophageal Manometry Test
At the Metabolic and Bariatric Surgery Program in Fresno, CA, we’re committed to matching the right bariatric surgery procedure with the right patient – that’s why our surgeons often order specialized medical tests for weight-loss surgery candidates. One of the tests we use is the esophageal manometry test, also known as a esophageal manometry study.
This video demonstrates how the esophageal manometry test is performed. Dr. Daniel Swartz, Assistant Clinical Professor of Surgery, at USCSF-Fresno performs the procedures on our own bariatric surgeon, Dr. Kelvin Higa.

What Is Esophageal Manometry Testing?
This non-invasive, non-surgical test allows our doctor to measure the strength of your esophageal sphincter and esophageal muscles, check for abnormal spasms, and check the movement (motility) of food from your mouth down into your stomach.
Your esophagus is a long, muscle-lined tube that runs between your throat and your stomach. In order to swallow and digest your food, the muscles of your esophagus need to create a gentle, wave-like motion; otherwise, you may experience regurgitation and severe gastric reflux. The same issues can occur if your esophageal sphincter is too tight, too loose, or does not contract as it should.
Why Bariatric Surgeons Use Esophageal Testing
Our bariatric surgeons may order an esophageal manometry test to determine if you are a good candidate for sleeve gastrectomy surgery, especially if you have trouble swallowing, experience severe gastric reflux, or have other issues that may indicate a problem with your esophageal sphincter or muscles.
What To Expect During An Esophageal Manometry Test
If you’ve been asked to complete an esophageal manometry test, be sure to tell your bariatric surgeon if you’re currently taking any medications since some drugs can impact the test results.
To prepare, you’ll need to refrain from eating or drinking to prevent vomiting.
During the test, you’ll be given a nasal numbing spray. This helps to reduce sensation in your throat and nose, making the procedure more comfortable. As you can see in the video above, this spray may cause a brief stinging sensation; however, this discomfort quickly passes.
A nurse will then insert a thin, well-lubricated, sterile surgical manometry probe with a series of metallic catheters into one of your nasal passages and down your throat. This probe is connected to a computer that measures pressure inside your esophageal sphincter and muscles.
The testing will take a total of about 10 to 15 minutes. During that time, you’ll be asked to lay as still as possible and refrain from speaking. You will be given one teaspoon of water at a time to swallow – this allows the nurse performing the test to monitor the movement through your esophagus and record the results for analysis.
Once the testing is complete, the nurse will gently remove the catheter. You may feel a slight soreness in your throat for a brief amount of time, otherwise, you can resume eating and drinking in 1 to 2 hours.
Your bariatric surgeon will review the results of your esophageal manometry study, discuss your options, and explain how the results impact your weight-loss journey.
