利用结肠镜息肉检出率估算腺瘤检出率的可行性探索

Feasibility of estimating adenoma detection rate based on polyp detection rate in colonoscopy

目的探索利用结肠镜息肉检出率(polyp detection rate,PDR)估算腺瘤检出率(adenoma detection rate,ADR)的可行性。方法采用单中心回顾性研究,利用2017年全年结肠镜数据计算PDR与ADR的换算系数,利用PDR和换算系数估算结肠镜医师的ADR,并与实际ADR进行一致性验证。结果最终纳入25112例结肠镜和20名结肠镜医师,换算系数为0.483,实际ADR和估算ADR的组内相关系数(ICC)为0.818(95%CI:0.596~0.924,P<0.01)。结论利用PDR估算ADR可行,但该方法仅是权宜之计,仍应重视建立规范电子数据库。

Objective To explore the feasibility of estimating adenoma detection rate(ADR)based on polyp detection rate(PDR)in colonscopy.Methods In the present single⁃center retrospective study,the conversion coefficient was calculated based on the total colonoscopy cases in 2017.ADR of each colonoscopists was estimated based on PDR and conversion coefficient,which was then verified compared with the actual ADR for consistency.Results A total of 25112 colonoscopies with 20 experienced colonoscopists were included.The overall conversion coefficient was 0.483.The intraclass correlation coefficient of the actual ADR and the estimated ADR was 0.818(95%CI:0.596⁃0.924,P<0.01).Conclusion It is feasible to estimate ADR based on PDR,but this method is only an expediency.More attention should be paid to the establishment of a standardized electronic database.
