Assessing AI's Role in Colonoscopy Withdrawal Time and Adenoma Detection
A Prospective Evaluation of the Correlation Between Artificial Intelligence-derived Effective Withdrawal Time and Adenoma Detection Rate
This study is testing if using artificial intelligence during colonoscopy can help doctors find more polyps by improving the time they spend looking around before finishing the procedure.

What this trial studies
This observational study aims to evaluate the relationship between artificial intelligence-derived effective withdrawal time (EWT) during colonoscopy and the adenoma detection rate (ADR) of endoscopists. Participants will undergo a colonoscopy where their bowel preparation will be monitored, and the AI system will assess the mucosal examination in real-time. The study will involve experienced endoscopists performing the procedure with high-definition equipment, and all detected polyps will be documented and removed during the withdrawal phase. The results will help determine if AI can enhance polyp detection rates by optimizing withdrawal times.
Who should consider this trial
Good fit: Ideal candidates are adults aged 40 and above who are scheduled for outpatient colonoscopy.
Not a fit: Patients with a history of inflammatory bowel disease, colorectal cancer, or other significant comorbidities may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved adenoma detection rates during colonoscopy, potentially reducing colorectal cancer incidence.
How similar studies have performed: While the use of AI in colonoscopy is gaining traction, this specific approach to correlating EWT with ADR is relatively novel and has not been extensively tested.
