Antroduodenal Manometry

An antroduodenal manometry, sometimes called a small bowel manometry, provides information about the muscle and nerve activity of the stomach and small bowel. The test can measure how strong and how well your child’s muscle contractions coordinate between the two organs.

To perform the test, a small flexible tube is inserted into your child’s nose, down the esophagus, through the stomach and into the small intestine. The tube is inserted when your child is asleep (from sedation or general anesthesia), but generally the manometry is completed when your child is awake. This test is administered by our specially trained team of physicians and nurses at the Lustgarten Center for GI Motility.

This test is only available at CHOP’s Main Campus.
