Researchers conducted a randomized controlled trial to see if adding a small amount of indigo carmine during endoscopy improved the detection of precancerous growths. The study included 366 patients who were at high risk for colorectal cancer, including those with inflammatory bowel disease.
The results showed that using this technique significantly increased the adenoma detection rate compared to standard white-light endoscopy. Specifically, it helped doctors find more flat adenomas and sessile serrated lesions, which are types of growths that can lead to cancer. The study suggests a clear link between the use of indigo carmine and better visibility for these specific types of polyps.
While the results are promising for improving screening accuracy, this is a specific clinical finding regarding endoscopic techniques. Patients with inflammatory bowel disease or other risk factors should discuss these findings with their doctors to see if this method is appropriate for their specific care plan.
