|Condition or disease||Intervention/treatment||Phase|
|Gastro-esophageal Reflux Disease (GERD)||Device: Mucosal Impedance||Not Applicable|
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||0 participants|
|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|
|Official Title:||Baseline Impedance Measured on High Resolution Esophageal Impedance Manometry to Discriminate GERD From Non GERD Patients|

Experimental: Mucosal Impedance
Patient's having a clinically indicated endoscopy, a high resolution impedance manometry and a 24 hour pH impedance study.
During the clinical endoscopy, the 2.13 mm catheter will be passed through the channel of the standard endoscope this is called an Intraluminal Impedance. This device has not been approved by the Food and Drug Administration (FDA) but it is considered to be minimal risk related to using it.
Device: Mucosal Impedance
During the clinical endoscopy, the 2.13 mm catheter will be passed through the channel of the standard endoscope this is called an Intraluminal Impedance. The Intraluminal impedance (made by Sandhill Scientific) has not been approved by the Food and Drug Administration (FDA) but it is considered to be minimal risk related to using it. The catheter gives the investigators a reading at each level.
Other Name: Impedance
- The mean impedance [ Time Frame: 2 years ]The mean impedance measured in Ohms as a measure of mucosal integrity and surrogate for GERD
- Maximal impedance measured on HRIM in GERD patients compared to minimal impedance in patients without GERD to determine a potential diagnostic cutoff value [ Time Frame: 2 years ]Evaluate the measurement of HRIM and mucosal impedance in patients that did not show gastroesophageal reflux disease per the HRIM and impedance testing
