Antro-pyloro-duodenal Motility in Idiopathic Gastroparesis
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.

Impaired gastric emptying may cause dyspeptic symptoms including nausea, vomiting and even nutritionnal impairment. Delay in gastric emptying may result from antro-pyloro-duodenal motility impairement.
Condition or disease
The aim of this study is therefore to measure antro-pyloro-duodenal motor activity in patients with idiopathic gastroparesis.
the main outcome is the pressure measured using pressure sensors within the antrum, the pylorus, and the first part of the duodenum. This will be measured during 3h fast. Pressures measured in the antrum, the pylorus, and the duodenum wiil be compared between healthy volunteers and gastroparetic patients
