Dye spray boosts Colonoscopy's hidden polyp detection
NCT ID NCT07601217
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether spraying a mix of acetic acid and indigo carmine dye during colonoscopy helps doctors find more precancerous polyps (called sessile serrated lesions) in the right side of the colon compared to standard white-light colonoscopy. About 2,689 adults aged 45-85 getting a screening colonoscopy will take part. The goal is to see if this simple dye technique can catch polyps that are often missed, potentially preventing more colorectal cancers.
