What this trial studies

This study aims to enhance the detection of colorectal polyps during colonoscopy by combining a balloon device that flattens folds in the colon with an artificial intelligence system designed for polyp detection. The research will involve an international multicenter prospective interventional cohort of 194 adult patients scheduled for various types of colonoscopy. By utilizing this combined approach, the study seeks to improve the adenoma detection rate, which is crucial for reducing the risk of interval colorectal cancer. Outcomes will be analyzed using regression modeling to account for confounding factors.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old who are scheduled for diagnostic, screening, or surveillance colonoscopy.

Not a fit: Patients with inflammatory bowel disease, known polyps or tumors, or those requiring therapeutic procedures may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly increase the detection rates of colorectal adenomas, leading to earlier intervention and better patient outcomes.

How similar studies have performed: While the combination of AI and visualization techniques in colonoscopy is a novel approach, previous studies have shown promise in improving detection rates with AI-assisted systems.
