Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older diagnosed with Barrett's esophagus who have confirmed dysplasia or intra-mucosal cancer and have achieved complete eradication of intestinal metaplasia.

Probably not a fit

Patients who are unable to provide consent, have refractory Barrett's esophagus, or have significant comorbidities that prevent safe participation will not benefit from this study.

What this trial studies

This clinical trial investigates the effectiveness of Wide-Area Trans-Epithelial Sampling (WATS-3D) in improving the detection of recurrent Barrett's esophagus (BE) after endoscopic eradication therapy (EET). The study aims to compare the results of WATS-3D tissue sampling with traditional forceps biopsies to determine if the new method can reduce missed diagnoses of dysplasia and prevent progression to esophageal cancer. Participants will include adults diagnosed with BE who have achieved complete eradication of intestinal metaplasia. The trial will be conducted at multiple leading medical institutions across the United States.

Why it matters

Potential benefit: If successful, this study could lead to earlier detection and treatment of Barrett's esophagus recurrence, potentially preventing the progression to esophageal cancer.

How similar studies have gone: Preliminary studies have shown that similar approaches using WATS-3D technology have improved detection rates in Barrett's esophagus surveillance.
