Improving Adenoma Detection and Resection: The Role of Tools, Techniques and Simulation-Based Mastery Learning

This comprehensive review addresses the critical role of colonoscopy in colorectal cancer (CRC) prevention. With CRC as one of the most common cancer types in men and women, high-quality colonoscopy is vital to reduce CRC incidence and mortality. Persistent gaps in quality, evidenced by interval CRCs and large variations in both provider adenoma detection rate (ADR) and resection methods, highlight the need to prioritize colonoscopy quality improvement through feedback and training.

This review delves into key factors influencing colonoscopy quality with lesion detection and removal. Excellent bowel preparation is necessary for effective colonoscopy, impacting lesion detection, ADR, procedure time, and complication risk. Optimal inspection techniques, encompassing provider maneuvers and utilization of technological devices such as distal attachment devices and artificial intelligence, hold promise in enhancing inspection quality. For optimal lesion resection, we explore cold snare polypectomy as a safe, cost-effective, and efficacious technique, particularly for diminutive and small polyps, and endoscopic mucosal resection for large (≥20 mm) polyps.

We outline the importance and critical need for quality assurance programs and to implement education science principles into endoscopy training. Innovative simulation-based mastery learning training, which includes various educational strategies to engage endoscopists in deliberate practice with assessment and feedback, holds great potential to efficiently scale the practice of high-quality colonoscopy to improve ADR and resection methods.
