Abstract
Background
Adenoma detection rate (ADR) is correlated with the risk of interval colorectal cancer and is considered as a quality benchmark for colonoscopy. Serrated polyp detection rate (SPDR) might be a more stringent indicator of quality in polyp detection.
Aims
To evaluate in a 2-year monocentric observational study patient-dependent and endoscopist-dependent factors influencing ADR and SPDR in daily practice.
Methods
We determined ADR and SPDR. We collected patient-dependent factors and endoscopist-dependent factors. Links between these data and detection rates were assessed by uni- and multivariate analysis.
Results
A total of 11682 colonoscopies were performed (female: 54.3%; male: 45.7%; median age 58) by 30 endoscopists (female: 9; male: 21). ADR and SPDR were 29.2% and 8%, respectively. In multivariate analysis, ADR was associated with patient-dependent factors: age (OR 1.044, CI 95% 1.040–1.048), male gender (OR 1.7, CI 95% 1.56–1.85), personal history of polyp/cancer (OR 1.53, CI 95% 1.3–1.9), and positive fecal immunochemical test (OR 2.47, CI 95% 2.0–3.1). In multivariate analysis, SPDR was associated with withdrawal time (OR 1.25, CI 95% 1.17–1.32), low volume activity (OR 1.3, CI 95% 1.1–1.52), and personal history of polyp/cancer (OR 1.61, CI 95% 1.15–2.25).
Conclusion
In this large series of routine colonoscopies, we found that ADR was mainly driven by patient-dependent conditions, i.e., age, male gender, colonoscopy indication for positive FIT, and a personal history of polyp or cancer. In contrast, SPDR was mainly related to endoscopist-dependent factor, i.e., withdrawal time and low volume activity.
