A Study to Evaluate Endoflip Normal Ranges Data in Healthy Volunteers

Normative EndoFlip Data on the Diameter and Distensibility of the Pylorus During Fasting and Postprandially in Healthy Females and Male Adults

The purpose of this research is to establish the normal range of diameter and distensibility of pylorus and the fasting and postprandial antro-pyloric motility in healthy adults.

An Endoflip catheter will be placed through the mouth into the stomach in order to measure distal antral contractile activity and pyloric diameter and distensibility during fasting and after the ingestion of a standard meal
