Esophageal Manometry
What Is Esophageal Manometry?
Esophageal manometry is a specialized test that measures how well the muscles of your esophagus work when you swallow.
The test evaluates:
- Muscle strength of the esophagus
- Coordination of swallowing muscles
- Movement of food from the throat to the stomach (peristalsis)
- Function of the Lower Esophageal Sphincter (LES), the valve between the esophagus and stomach
This test helps identify disorders that can cause difficulty swallowing, chest discomfort, or reflux symptoms.
Why Is Esophageal Manometry Performed?
Your provider may recommend esophageal manometry if you experience:
- Difficulty swallowing (dysphagia)
- Food getting stuck when swallowing
- Chronic heartburn or reflux
- Chest pain not related to the heart
- Regurgitation of food or liquids
- Suspected esophageal motility disorders
It is also commonly performed before certain anti-reflux procedures or surgery.
What Does the Test Measure?
The study evaluates:
- Strength of esophageal muscle contractions
- Coordination of swallowing
- Pressure within the esophagus
- Relaxation and function of the LES
This information helps diagnose conditions such as:
- Achalasia
- Esophageal spasms
- Ineffective esophageal motility
- Other swallowing disorders
How Is the Test Performed?
- A thin, flexible pressure-sensitive catheter is gently passed through the nose
- The catheter travels through the esophagus and into the stomach
- You will be asked to swallow small amounts of water
- Specialized equipment records pressure and muscle activity
The test creates a detailed map of how your esophagus functions during swallowing.
How Long Does It Take?
- Approximately 20–30 minutes
- Performed as an outpatient office procedure
Will I Be Awake?
Yes.
- No sedation is used
- You remain awake throughout the procedure
- A topical numbing medication may be applied inside the nose to improve comfort
Is It Painful?
Most patients tolerate the procedure well.
You may experience:
- Mild pressure in the nose or throat
- Temporary gagging
- Mild coughing
- Brief nausea during catheter placement
These sensations typically improve quickly once the catheter is in position.
Will the Tube Affect My Breathing?
No.
- The catheter does not interfere with breathing
- You will be able to breathe normally throughout the procedure
Do I Need Preparation?
Preparation may include:
- Fasting before the procedure
- Avoiding food and drinks for a specified period
- Temporary discontinuation of certain medications if instructed
Some medications can affect test results, including:
- Proton Pump Inhibitors (PPIs)
- H2 Blockers
- Other medications that affect esophageal function
Be sure to discuss all medications with our office before your procedure.
Can I Drive Home?
Yes.
- No sedation is used
- You may drive yourself home
- Most patients return to normal activities immediately
Risks and Safety
Esophageal manometry is a very safe procedure.
- Serious complications are extremely rare
- No radiation is used
- No anesthesia is required
- Most patients experience only temporary mild discomfort
Possible side effects include:
- Mild nasal irritation
- Sore throat
