Antroduodenal Manometry
Also known as: antro-duodenal manometry.
What is antroduodenal manometry?
If a person has problems digesting food or passing it through the body, an antroduodenal manometry may be performed. This procedure involves passing a catheter into the antrum (lower part of the stomach) and duodenum (upper part of the small intestines) in order to check their function.
What happens during the procedure?
- The catheter is inserted into the nose and guided into the stomach and intestines.
- The catheter has sensors along its length that measure pressure in the stomach and duodenum.
- Once the catheter is in place, it is taped to fix it in position.
- Then the patient rests for a bit prior to the measurements being taken.
- Measurement are taken for 4 to 5 hours, and then for another hour or two after the patient receives a meal.
Is any special preparation needed?
You’ll need to avoid food and drink for a set period of time before the procedure.
What are the risk factors?
Bleeding, infection, tearing of the stomach or intestines or equipment failure are possible complications of antroduodenal manometry.Reviewed by: Carrie Firestone Baum, MD
