Comparing cold and hybrid techniques for removing large colon polyps
Official title: Randomized Trial of Cold EMR Compared to Hybrid Cold EMR.
Run by The Cleveland Clinic · NCT06937671 · Data updated 2026-11-12
This study is testing if a new way of removing large colon polyps that combines two techniques can lower the chances of the polyps coming back and reduce complications for adults with certain types of polyps.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 years or older with large colon polyps measuring at least 20 mm and specific morphological characteristics.
✕Probably not a fit
Patients with previous failed resection attempts, suspected deep submucosal invasion, or inflammatory bowel disease may not benefit from this study.

What this trial studies
This clinical trial aims to determine whether a hybrid approach combining cold endoscopic mucosal resection (EMR) with traditional cold EMR can reduce the risk of polyp recurrence while minimizing complications in patients with large colon polyps. Participants will undergo EMR and will return for a follow-up endoscopy in 3-6 months to assess for any recurrence of polyps. The study focuses on adults with specific polyp characteristics, ensuring a targeted approach to treatment.
Why it matters
Potential benefit: If successful, this study could lead to improved outcomes for patients by reducing the likelihood of polyp recurrence after removal.
How similar studies have gone: While this approach is innovative, similar studies have shown promise in improving outcomes with EMR techniques.
