The adenoma detection rate (ADR) is the most important quality indicator for the prevention of colorectal cancer but serrated polyps are also precursor lesions of the disease. The aim of our study was to compare the detection rate of proximal serrated polyps (PSPs) and that of clinically significant serrated polyps (CSSPs) between endoscopists and analyze the relation of those parameters to the ADR.
An observational, prospective, cross-sectional study was conducted on all patients that underwent colonoscopy at the Policlínico Peruano Japonés within the time frame of July 2015 and August 2016. The ADR and PSP and CSSP detection rates between endoscopists were compared through multivariate logistic regression and the association between those parameters was calculated through the Pearson correlation coefficient.
The study included 15 endoscopists and 1,378 colonoscopies. The PSP detection rate ranged from 1.8-17% between endoscopists and had an almost perfect correlation with the CSSP detection rate (p = 0.922), as well as strongly correlating with the ADR (p = 0.769).
There was great variability in the PSP detection rate between endoscopists. It also had an almost perfect correlation with the CSSP detection rate and strongly correlated with the ADR. Those results suggest a high CSSP miss rate at endoscopy and a low PSP detection rate.
腺瘤检出率（ADR）是预防结直肠癌最重要的质量指标，但锯齿状息肉也是该疾病的前驱病变。我们研究的目的是比较内镜医师之间近端锯齿状息肉（PSP）和临床显著锯齿状息肉（CSSP）的检出率，并分析这些参数与ADR的关系。
对2015年7月至2016年8月期间在秘鲁日本综合医院接受结肠镜检查的所有患者进行了一项观察性、前瞻性横断面研究。通过多因素逻辑回归比较内镜医师之间的ADR以及PSP和CSSP的检出率，并通过Pearson相关系数计算这些参数之间的关联。
该研究纳入了15名内镜医师和1378例结肠镜检查。内镜医师之间的PSP检出率在1.8%至17%之间，与CSSP检出率几乎呈完美相关（p = 0.922），与ADR也呈强相关（p = 0.769）。
内镜医师之间的PSP检出率存在很大差异。它与CSSP检出率几乎呈完美相关，与ADR呈强相关。这些结果表明内镜检查时CSSP漏诊率高，PSP检出率低。
