Structured Approach to Colonoscopy Technique Optimization: A Single-Center Experience with Novice Endoscopists
Published on: July 11, 2025
EQUIPping ourselves for future quality improvements in colonoscopy.
Colonoscopy significantly reduces colorectal cancer (CRC) mortality, but quality improvements are needed. Future efforts should focus on detecting and removing serrated pathway lesions, not just adenomas, to further reduce interval cancers.
Area of Science:
- Gastroenterology
- Oncology
- Cancer Prevention
Background:
- Colonoscopy is a key tool for colorectal cancer (CRC) screening, with an estimated 50% reduction in mortality.
- Current quality improvement initiatives primarily target the adenoma detection rate (ADR).
- While ADR improvements have been achieved, their sufficiency in reducing CRC is debated.
Discussion:
- The focus on ADR may overlook other significant pathways to CRC, such as the serrated pathway.
- Interval cancers, occurring after a negative colonoscopy, suggest limitations in current detection strategies.
- The serrated pathway is increasingly recognized as a critical contributor to post-colonoscopy CRC.
Key Insights:
- Improving ADR alone may not be sufficient to maximize the benefits of colonoscopy.
- Detecting and completely removing serrated lesions is crucial for reducing interval CRC.
- A balanced approach to quality improvement, encompassing both adenoma and serrated lesion detection, is warranted.
Outlook:
- Future research should evaluate the impact of serrated lesion detection and resection on CRC mortality.
- Developing standardized methods for identifying and managing serrated polyps during colonoscopy is essential.
- Enhanced training and quality metrics focusing on the serrated pathway could further optimize colonoscopy effectiveness.
