Summary
Proximal serrated polyp detection rate (pSPDR) did not differ between screening and other colonoscopy indications, unlike adenoma detection rate (ADR). pSPDR may serve as a complementary quality indicator for colonoscopists.
Area of Science:
- Gastroenterology
- Endoscopy
- Cancer Screening
Background:
- Colonoscopy quality is crucial for colorectal cancer (CRC) screening effectiveness.
- Adenoma detection rate (ADR) is a primary quality indicator.
- Proximal serrated polyp detection rate (pSPDR) is a potential complementary indicator.
Purpose of the Study:
- To compare ADR and pSPDR between screening colonoscopies and those for other indications (surveillance, diagnosis).
- To evaluate pSPDR as a quality metric independent of indication.
Main Methods:
- Historical cohort study of 981 patients undergoing colonoscopy.
- Patients divided into screening (n=428) and other indications (n=553) groups.
- Comparison of ADR and pSPDR between the two groups.
Main Results:
- Adenoma detection rate was higher in the 'other indications' group (50.6%) versus the screening group (44.6%; P=0.03).
- Proximal serrated polyp detection rate showed no significant difference between groups (13.6% vs 13.7%; P=0.931).
- No significant differences in mean age or sex distribution between groups.
Conclusions:
- Proximal serrated polyp detection rate is comparable across different colonoscopy indications.
- pSPDR can serve as a complementary quality indicator to ADR.
- This finding supports pSPDR's utility for endoscopists, particularly those with lower colonoscopy volumes.
