Screening colonoscopy: should we focus more on technique and less on technology?

Area of Science:

• Gastroenterology
• Endoscopy
• Cancer Prevention

Background:

• High-quality colonoscopic surveillance is proven to reduce colorectal cancer (CRC) incidence and mortality.
• Technological advancements such as high-resolution scopes and chromoendoscopy aim to enhance adenoma detection rates.
• However, factors beyond equipment significantly influence the quality of colonoscopic surveillance.

Purpose of the Study:

• To review recent studies on non-technological factors impacting adenoma detection during colonoscopy.
• To highlight the importance of endoscopist experience, patient positioning, withdrawal techniques, and bowel preparation in colonoscopic surveillance quality.
• To underscore the role of these factors in improving adenoma or polyp detection rates.

Main Methods:

• Review of recent scientific literature focusing on colonoscopy quality metrics.
• Analysis of studies investigating the impact of endoscopist experience on adenoma detection.
• Evaluation of research on the influence of procedural techniques (withdrawal, position changes) and bowel preparation on polyp detection.

Main Results:

• Endoscopist experience is a significant determinant of adenoma detection rates.
• Optimal withdrawal time and patient repositioning maneuvers can enhance visualization and polyp detection.
• Effective bowel preparation is essential for clear visualization and accurate adenoma detection during colonoscopy.

Conclusions:

• Improving colonoscopic surveillance quality requires a multifaceted approach, integrating technological advancements with optimized procedural techniques and endoscopist expertise.
• Attention to factors such as endoscopist skill, patient positioning, withdrawal technique, and bowel preparation is critical for maximizing adenoma detection.
• These non-technological aspects are vital for enhancing the effectiveness of colonoscopy in reducing colorectal cancer rates.
