Antroduodenomanometrie

Antroduodenomanometrie is a diagnostic procedure used to evaluate the motor function of the antrum of the stomach and the duodenum. It involves measuring the pressure waves and muscle contractions within these regions. The procedure typically requires the placement of a specialized catheter through the nose or mouth, down into the stomach and duodenum. This catheter is equipped with pressure sensors that record the electrical and mechanical activity of the smooth muscles. The patient may be given a meal or specific medications to stimulate contractions, allowing for the assessment of normal or abnormal responses. Antroduodenomanometrie can help diagnose conditions such as gastroparesis, intestinal pseudo-obstruction, and other motility disorders. The data collected can assist in determining the underlying cause of symptoms like nausea, vomiting, abdominal pain, and feeling full quickly. Interpretation of the manometric findings is performed by a trained gastroenterologist to guide treatment decisions.
