Colonoscopy Quality and Strategies for Improvement

Area of Science:

• Gastroenterology
• Oncology
• Preventive Medicine

Background:

• Colonoscopy is vital for colorectal cancer (CRC) screening, but its effectiveness relies on endoscopist skill.
• Variations in colonoscopist performance can lead to missed lesions, resulting in post-colonoscopy CRC (PCCRC).
• High-quality colonoscopy is essential for maximizing CRC prevention benefits.

Purpose of the Study:

• To review the significance of colonoscopy quality indicators for improving CRC screening.
• To highlight practices that enhance colonoscopist performance and reduce PCCRC.
• To emphasize the role of adenoma detection rate (ADR) as a key quality metric.

Main Methods:

• Review of key process indicators: bowel preparation, cecal intubation, and withdrawal time.
• Focus on adenoma detection rate (ADR) as the primary quality metric and predictor of PCCRC.
• Evaluation of interventions and technologies aimed at improving ADR, including withdrawal techniques and AI.

Main Results:

• Key process indicators are linked to ADR and PCCRC risk.
• Adenoma detection rate (ADR) is the most reliable predictor of PCCRC.
• Serrated polyp detection is inversely associated with PCCRC risk.
• Interventions like enhanced withdrawal techniques and technology increase ADR.
• AI shows promise but fundamental techniques remain critical.

Conclusions:

• Continuous improvement in colonoscopist performance is necessary for effective CRC prevention.
• Understanding and implementing quality indicators are vital for daily practice.
• High-quality colonoscopy, focusing on complete mucosal exposure, leads to better CRC prevention outcomes.
