New study reveals best way to spot dangerous colon growths

NCT ID NCT01521091

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study compared three methods used during colonoscopy to predict whether colorectal growths are cancerous: narrow band imaging (NBI), indigo carmine staining, and acetic acid staining. Researchers studied 565 patients with at least one lesion 6mm or larger. The goal was to see which method most accurately identifies invasive cancer. Results suggest NBI may be the best first choice.
