Study, antro-duodenal motility


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 through the nose, throat, esophagus, and stomach until the tip of the 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.
