When is an antro-duodenal motility study used?
An antro-duodenal motility study is used to diagnose a motility disorder of the stomach or small intestine, that is, a condition of abnormal function of the muscles of the stomach and/or small intestine. Such abnormal function usually is suspected when there are symptoms and signs of obstruction to the flow of food through the stomach and intestines. These symptoms usually are nausea, vomiting, and intestinal distention (enlargement). The obstruction is a direct result of the inability of the abnormally functioning muscles to propel food through the stomach and intestines. One common cause of motility disorders of the stomach and intestines is diabetes mellitus.
