Motility refers to the movement of contents through the gastrointestinal tract from mouth to anus.
Esophageal (esophagus) Motility Study, Antroduodenal (stomach, upper small intestine) Manometry and Colonic (large intestine) Motility Study
These tests are performed by placing catheters with special pressure sensors in the esophagus, stomach, upper small intestine and large intestine to measure the frequency and strength of muscular contractions in these areas of the body. These tests may be performed in children with longstanding swallowing problems, abdominal distention, feeding intolerance or chronic constipation to see if their symptoms are due to a motility problem.
A device with three small balloons is placed in the child's rectum to measure muscle contractions. Younger children are sedated with general anesthesia while older children are usually able to remain awake during the test. This test is performed in children with severe constipation and may also be used to diagnose Hirschprung's disease.
