Definition of Antro-duodenal motility study
Antro-duodenal motility study: An antro-duodenal motility
study is a study for detecting and recording the contractions of the
muscles of the stomach and the first part of the small intestine, the
duodenum. It is performed to diagnose problems with how the muscles
of the stomach and small intestine are working.
An antro-duodenal motility study requires the passage of a tube

tube lies in the small intestine. The tube senses when the muscles of
the stomach and small intestine contract and squeeze the tube
tightly. The contractions are recorded for analysis by a computer.
