Assessing AI's Role in Colonoscopy Withdrawal Time and Adenoma Detection
A Prospective Evaluation of the Correlation Between Real Time 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 and improve the time they spend checking the colon in people aged 40 and older.

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 aged 40 and above will undergo outpatient colonoscopy, where their bowel preparation will be monitored, and the colonoscopy video will be analyzed by AI to determine the EWT. The study will compare the AI-derived EWT with standard withdrawal times and assess various colonoscopy outcomes, including polyp detection rates. The goal is to enhance the effectiveness of colonoscopy procedures through real-time AI monitoring.
Who should consider this trial
Good fit: Ideal candidates are adults aged 40 or older who are scheduled for outpatient colonoscopy.
Not a fit: Patients with a history of inflammatory bowel disease, colorectal cancer, or other significant gastrointestinal conditions may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could improve adenoma detection rates during colonoscopy, leading to better early detection of colorectal cancer.
How similar studies have performed: While the use of AI in colonoscopy is a growing field, this specific approach to measuring withdrawal time and its correlation with adenoma detection rates is relatively novel.
