Barrett's Esophagus

Device, OFDI, Tethered Capsule Endomicroscopy
Brief summary
The goal of this research is to test a distal scanning capsule and a compact redesigned version of the OFDI imaging system in healthy and BE participants to assess ease of use, safety and feasibility in preparation for its use in a multicenter clinical trial.
Detailed description
Ten healthy participants and ten participants with a previous diagnosis of Barrett's Esophagus (BE) will be enrolled in the study. The capsule is attached to a string-like tether which allows the operator to control as well as navigate the capsule as it progresses down the esophagus using peristalsis. Images of the esophagus will be acquired in real time to be analyzed later.

Inclusion criteria
* A previous diagnosis of BE (not an inclusion criteria for healthy volunteers) * Participants 18 years and older with a previous diagnosis of GERD * Participants 14 years and older with a previous diagnosis of EoE (not an inclusion criteria for healthy volunteers) * Health participants over the age of 18 but less than 85 years of age * Participants must be able to give informed consent * Participants must have no solid food for 4 hours prior to the procedure, and only clear liquids for 2 hours prior to the procedure.
