Summary
Sessile serrated lesion detection rates (SSLDR) significantly improved from 2008 to 2020, reaching 7.94%. While detection rates increased, variations among endoscopists persist, highlighting the need for continuous reevaluation of targets.
Area of Science:
- Gastroenterology
- Endoscopy
- Cancer Prevention
Background:
- Sessile serrated lesions (SSLs) are precursors to colorectal cancer.
- Accurate detection of SSLs during colonoscopy is crucial for effective cancer prevention.
- Variability in SSL detection rates among endoscopists is a known challenge.
Purpose of the Study:
- To assess the trend of sessile serrated lesion detection rate (SSLDR) from 2008 to 2020.
- To model a local, aspirational target SSLDR for an academic medical center.
- To analyze SSLDRs among gastroenterology fellows and their relation to colonoscopy volume.
Main Methods:
- Retrospective analysis of screening colonoscopies for average-risk patients (2008-2020).
- Calculation of unadjusted and model-adjusted SSLDRs for individual endoscopists and fellows.
- Use of mixed effects logistic regression to identify predictors of SSL detection.
Main Results:
- Model-adjusted SSLDRs demonstrated a significant increase from 0.37% in 2008 to 7.94% in 2020.
- Gastroenterology fellows showed lower SSL detection odds in their first year compared to their second year.
- Variance in SSLDRs among endoscopists remained a notable finding.
Conclusions:
- SSLDR has shown consistent and significant improvement over the study period.
- The 2020 SSLDR of 7.94% is proposed as a benchmark for current endoscopists and trainees.
- Ongoing monitoring and reevaluation of SSLDR targets are recommended to address persistent inter-endoscopist variability.
