This study will evaluate the role the balloon mucosal impedance may have in diagnosing and monitoring the patients with Eosinophilic Esophagitis. We will compare the results of the balloon mucosal impedance in patients with Eosinophilic esophagitis and controls.
The standard diagnostic evaluation for EoE includes upper endoscopy with esophageal biopsies. Recently we completed the study "Mucosal impedance in eosinophilic esophagitis and the effect of treatment" using a new technology allowing for direct assessment of mucosal impedance at the time of routine upper endoscopy to assess esophageal integrity and disease activity and alevate the need for biopsies. For this study, Sandhill Scientific has customized a Mucosal Impedance balloon (MI) assembly to provide precise measurements over a broad area of esophageal epithelium, while eliminating the fluids and spanning across a 10 mm luminal area using the same direct assessment as the mucosal impedance at the time of routine upper endoscopy.
Study Type
OBSERVATIONAL
Enrollment
28
During the clinical endoscopy (a standard procedure that allows your doctor to look at the inside of your swallowing tube), the 2 mm catheter (tiny tube), called an Intraluminal Impedance Balloon, will be passed through the channel of the standard endoscope. o The catheter (tiny tube) will be placed through the endoscope in your esophagus (swallowing tube) for two minutes, readings from the catheter will be recorded.

Diminished mucosal impedance in patients with Eosinophilic Esophagitis
Patient with eosinophilic esophagitis have diminished mucosal impedance, reflecting increased permeability to allergens occurring in the esophagus. The impedance measurements are also variable throughout the esophageal mucosa reflecting the patchy histology of eosinophilic esophagitis.
