Brief summary

The main purpose of this research is to test the feasibility and tolerability of the tethered capsule Optical Frequency Domain Imaging (OFDI)

Detailed description

A total of 56 subjects with Barrett's Esophagus, EoE and healthy volunteers will be asked to swallow the OFDI capsule while being unsedated. The capsule is attached to a tether that allows the capsule operator to navigate the capsule as it progresses down the esophagus using natural propulsion called peristalsis as well as to bring it back up to pulled out of the mouth when the procedure is done. As the capsule progresses down the esophagus, multiple, two dimensional, microscopic cross- sectional images of the esophagus are acquired.

Pre-assignment details

In this feasibility study we try to establish the overall number of participants who are able to swallow the capsule and provide us with quality imaging using this new technology. At this point we do no distinguish tolerability separately in each of the three groups and are treating them as one.
