Brief Summary:
The main purpose of this research is to test the feasibility and tolerability of the tethered capsule Optical Frequency Domain Imaging (OFDI) screening probe in healthy subjects, patients with Barrett's Esophagus and Eosinophilic Esophagitis.

Condition or disease Intervention/treatment Phase
Barrett's Esophagus Eosinophilic Esophagitis Device: OFDI Capsule Not Applicable

Detailed Description:

A total of 54 subjects comprising of healthy volunteers, patients with Eosinophilic Esophagitis (EoE) or Barrett's Esophagus 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.

Imaging of the esophagus using the OFDI Capsule and system


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Feasibility of OFDI Imaging in subjects swallowing the OFDI capsule [ Time Frame: Images will be acquired during the OFDI imaging session which should take an average of 5 minutes ]
    An investigator will assess the quality of the recorded images and movies obtained with each exam after the imaging is completed.


Secondary Outcome Measures :
  1. Tolerability of OFDI Imaging in subjects swallowing the OFDI capsule [ Time Frame: Images will be acquired during the OFDI imaging session which should take an average of 5 minutes ]
    After participating in the study, the subject will be asked for feedback about tolerability of the procedure using a questionnaire.
