Pilot Study for TCE Imaging of the Esophagus Using an OFDI Capsule With a Compact Imaging System

October 20, 2025 updated by: Guillermo Tearney, Massachusetts General Hospital

Pilot Study for TCE (Tethered Capsule Endomicroscopy) Imaging of the Esophagus Using an OFDI (Optical Frequency Domain Imaging) Capsule With a Compact Imaging System

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.

Accepts Healthy Volunteers

Yes

Description

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)
