Transient Lower Esophageal Sphincter Relaxations and High Resolution Manometry
Recruitment status was: Recruiting
Transient lower esophageal sphincter relaxations (tLESr) are the main mechanism of gastro-oesophageal reflux disease. They occur without any deglutition in patients but also in healthy volunteers. They are induced by meal.
The gold standard to detect tLESr is esophageal manometry using perfused Dentsleeve probe.
Esophageal high resolution manometry with solid state sensors was developed in the 90s. The examination is easier and more accurate than perfused manometry. The aim of this study is to validate in healthy volunteers the use of high resolution manometry (Sierra Scientific Instruments, California CA) to detect tLESr.
|Healthy Volunteers||Device: Esophageal high resolution manometry associated or not with manometry with perfused Dentsleeve probe (as determined by randomization)|
|Study Design:||Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
|Official Title:||Transient Lower Esophageal Sphincter Relaxations Detection Using High Resolution Manometry. Validation in Healthy Volunteers.|
- The primary outcome is to demonstrate that high resolution manometry allows the detection of meal-induced tLESr. All recordings will be analyzed at the end of each examination and reviewed at the end of the enrolment.
- To compare the number of tLESr detected by high resolution manometry and those detected by manometry with perfused dentsleeve probe.
- To define the characteristics (duration, relaxation amplitude) of high resolution manometry-detected tLESr.

|Estimated Primary Completion Date:||December 2009 (Final data collection date for primary outcome measure)|
This is a descriptive study to compare two techniques (manometry with perfused dentsleeve probe vs high resolution manometry for the identification of tLESr). Each subject is his own control.
The date of perfused manometry is randomized to avoid bias due to examinations' order.
Device: Esophageal high resolution manometry associated or not with manometry with perfused Dentsleeve probe (as determined by randomization)
