Meticulous cecal image documentation at colonoscopy is associated with improved polyp detection

Area of Science:

• Gastroenterology
• Endoscopy
• Medical Imaging

Background:

• No prior studies have correlated cecal image quality with colonoscopy outcomes.
• Colonoscopy is a key procedure for colorectal cancer screening and diagnosis.

Purpose of the Study:

• To investigate the relationship between the quality of cecal image documentation and polyp detection rates (PDR).
• To test the hypothesis that better image documentation leads to higher PDR.

Main Methods:

• Retrospective analysis of 651 colonoscopies performed by 16 experienced endoscopists.
• Development and application of a novel Cecal Image Documentation Score (CIDS) to quantify image quality.
• Assessment of the correlation between CIDS and PDR, including right-sided PDR.

Main Results:

• A mean CIDS > 2.0 was associated with a significantly higher PDR (27.8%) compared to a mean CIDS < 2.0 (15.2%).
• Higher CIDS was an independent predictor of increased PDR (OR 2.53) and right-sided PDR (OR 3.67).
• Endoscopists with higher CIDS had a higher mean polyps per procedure (PPP).

Conclusions:

• Meticulous cecal image documentation is linked to improved polyp detection during colonoscopy.
• Enhanced quality of cecal imaging is associated with better detection of polyps, particularly in the right colon.
