Testing a new imaging capsule for Barrett's Esophagus

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

Not applicable Interventional Massachusetts General Hospital · NCT02947971

This study is testing a new imaging capsule to see if it can safely and easily take pictures of the esophagus in both healthy people and those with Barrett's Esophagus.

What this trial studies

This research aims to evaluate a novel distal scanning capsule and a compact optical frequency domain imaging (OFDI) system in both healthy individuals and those diagnosed with Barrett's Esophagus (BE). The study will enroll ten healthy volunteers and ten BE patients to assess the ease of use, safety, and feasibility of the imaging system. The capsule, tethered for controlled navigation, will capture real-time images of the esophagus, which will be analyzed post-procedure. This pilot study serves as a precursor to a larger multicenter clinical trial.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 to 70 with a previous diagnosis of Barrett's Esophagus or healthy volunteers meeting the study criteria.

Not a fit: Patients over 70 years of age or those with swallowing difficulties, strong gag reflex, or esophageal conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this imaging technique could enhance the diagnosis and monitoring of Barrett's Esophagus, leading to better patient outcomes.

How similar studies have performed: While this approach is innovative, similar imaging techniques have shown promise in other studies, indicating potential for success.
