What is esophageal manometry?
Esophageal manometry is a diagnostic test that shows how well your esophagus is working. Your esophagus is the tube that moves food and liquids from your mouth to your stomach. This test measures the strength and rhythm of the muscles in your esophagus as you swallow.
At MedStar Health, our team of highly experienced gastroenterologists works together to diagnose and treat both simple and complex digestive (GI) conditions, including esophageal motility disorders. We take the time to understand each patient’s unique symptoms, health history, and personal needs. Whether you’re dealing with trouble swallowing, acid reflux, achalasia, or other esophageal issues, we use advanced testing like esophageal manometry to help guide your care and get you the relief you deserve.
Who might benefit from esophageal manometry?
Your doctor may recommend esophageal manometry if you have:
-
Difficulty swallowing (dysphagia)
-
Frequent or severe acid reflux or heartburn
-
A known or suspected condition like achalasia, which affects how the esophagus muscles work
-
Chest pain unrelated to your heart
-
A feeling that food gets stuck in your throat or chest
-
Plans for certain types of esophagus or stomach surgery
This test helps your care team better understand your symptoms and plan the right treatment.
Benefits and possible risks
This simple test is quick, easy, and non-invasive, allowing your care team to get necessary answers to address the root cause of your symptoms. Other benefits include:
- Provides detailed information about how your esophagus muscles are working
- Helps diagnose swallowing disorders and reflux problems
- Can guide treatment decisions or help prepare for surgery
Esophageal manometry is a safe, well-tolerated procedure. Most people feel only mild discomfort. Possible side effects include:
- A brief gagging feeling when the tube is inserted, although your doctor may use a lidocaine spray to help prevent this.
- A sore throat or stuffy nose afterward, which usually goes away quickly.
How it works
A small, flexible tube (called a catheter) is gently placed through your nose and guided down into your esophagus and stomach. Before the tube is inserted, your care team will apply a medication to your nose and throat to make them numb and help you feel more comfortable.
The catheter is connected to a computer that measures the strength and pattern of muscle movements in your esophagus. As the test begins, a nurse will ask you to swallow small sips of water. The computer records how your esophagus muscles move the liquid toward your stomach.
The entire test usually takes about 30 minutes.
