BACKGROUND The adenoma detection rate (ADR) is a widely accepted quality benchmark for screening colonoscopy but can be burdensome to calculate. Previous studies have shown good correlation between polyp detection rate (PDR) and ADR, but this has not been validated in trainees. Additionally, the correlation between PDR and detection rates for sessile serrated polyps (SSPDR) and advanced neoplasia (ANDR) is not well studied. AIMS We investigated the relationship between PDR and ADR, SSPDR, and ANDR in trainees. METHODS We examined 1600 outpatient colonoscopies performed by 24 trainees at a VA hospital from 2014 to 2017. Variables collected included patient demographics, year of fellowship, colonoscopy indication, and endoscopic and histologic findings. We calculated the overall ratios of PDR to ADR, SSPDR, and ANDR to assess the correlation between measured and calculated ADR, SSPDR, and ANDR, which is equivalent to the correlation between PDR and measured ADR, SSPDR, and ANDR. RESULTS The overall PDR, ADR, SSPDR, and ANDR were 72%, 52%, 2%, and 14%. PDR (48%) was highest in the left colon, while ADR (32%) and ANDR (7%) were highest in the right colon (p < 0.001 for all). The overall ADR/PDR, SSPDR/PDR, and ANDR/PDR ratios were 0.73, 0.03, and 0.20. Correlation between PDR and ADR was highly positive overall (r = 0.87, p < 0.0001) and stronger in the right (r = 0.91) and transverse (r = 0.94) colon than the left colon (r = 0.80). Correlation between PDR and overall SSPDR and ANDR were not statistically significant. CONCLUSIONS PDR can serve as a surrogate measure of ADR to monitor colonoscopy quality in gastroenterology fellowship.

见习内窥镜医师的息肉检出率与腺瘤检出率密切相关。

背景 腺瘤检出率 (ADR) 是一种广泛接受的结肠镜筛查质量基准，但计算起来可能很麻烦。先前的研究表明息肉检出率 (PDR) 与 ADR 之间存在良好的相关性，但这尚未在受训者中得到验证。此外，PDR 与无蒂锯齿状息肉 (SSPDR) 和晚期肿瘤 (ANDR) 检出率之间的相关性尚未得到充分研究。目的 我们调查了受训者中 PDR 与 ADR、SSPDR 和 ANDR 之间的关系。方法 我们检查了 2014 年至 2017 年在 VA 医院的 24 名受训者进行的 1600 次门诊结肠镜检查。收集的变量包括患者人口统计数据、研究年限、结肠镜检查指征以及内窥镜和组织学检查结果。我们计算了 PDR 与 ADR、SSPDR、ANDR 来评估实测和计算 ADR、SSPDR 和 ANDR 之间的相关性，相当于 PDR 与实测 ADR、SSPDR 和 ANDR 之间的相关性。结果 总体 PDR、ADR、SSPDR 和 ANDR 分别为 72%、52%、2% 和 14%。左侧结肠的 PDR (48%) 最高，而右侧结肠的 ADR (32%) 和 ANDR (7%) 最高（p < 0.001）。总体 ADR/PDR、SSPDR/PDR 和 ANDR/PDR 比率分别为 0.73、0.03 和 0.20。PDR 和 ADR 之间的相关性总体上呈高度正相关 (r = 0.87, p < 0.0001)，并且在右侧 (r = 0.91) 和横结肠 (r = 0.94) 中比左侧结肠 (r = 0.80) 更强。PDR 与总体 SSPDR 和 ANDR 之间的相关性没有统计学意义。结论 PDR 可以作为 ADR 的替代指标，以监测胃肠病学研究中结肠镜检查的质量。
