Study Type : Observational
Estimated Enrollment : 15 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Assessment of Normal Values of Esophagogastric Junction (EGJ) Distensibility in Healthy Volunteers
Study Start Date : November 2013
Estimated Primary Completion Date : August 2014
Estimated Study Completion Date : August 2014

Healthy volunteers

Primary Outcome Measures :
  1. normal values of esophagogastric junction (EGJ) distensibility (mm2/mmHg) in healthy volunteers as measured with the EndoFLIP device [ Time Frame: 3 months ]
    EGJ distensibility as measured by the index of the narrowest cross sectional area (mm2) and the corresponding intrabag pressure (mmHg)

Secondary Outcome Measures :
  1. Establishing a cut-off value of EGJ distensibility (mm2/mmHg) based on the 90% percentile distribution of measurements performed in healthy volunteers. [ Time Frame: 3 months ]
