What is antro-duodenal manometry?
The term antro-duodenal comes from the two words "antrum" and "duodenum." The antrum is the area at the bottom of the stomach, which prepares food to go into the small intestine. The duodenum is the first part of the small intestine, which receives the food. (Figure 1)
Manometry is the measurement of pressure or contractions in the small intestine. The purpose of antro-duodenal manometry is to determine how well the antrum and the duodenum work together.
