The adenoma detection rate (ADR) is a quality benchmark for colonoscopy, influenced by several factors including bowel preparation, withdrawal time, and withdrawal technique.
To assess the impact of video recording of all colonoscopies on the ADR.
Comparison of two cohorts of patients undergoing colonoscopy before and after implementation of video recording.
Academic outpatient endoscopy facility.
This study involved asymptomatic, average-risk adults undergoing screening colonoscopy.
Video recording of all colonoscopy procedures. Polyp findings and withdrawal times were recorded for 208 consecutive screening colonoscopies. A policy of video recording all colonoscopies was implemented and announced to the staff. Data on another 213 screening colonoscopies were subsequently collected.
Adenoma detection rate, withdrawal time, advanced polyp detection rate, hyperplastic polyp detection rate.
At least one adenoma was found in 38.5% of patients after video recording versus 33.7% before video recording (P = .31). There was a significant increase in the hyperplastic polyp detection rate (44.1% vs 34.6%; P = .046). Most endoscopists had a numerical increase in their ADRs, but only one was significant (57.7% vs 22.6%; P < .01). There were trends toward higher detection of adenomas of <5 mm (59.1% vs 52%; P = .23) and right-sided adenomas (40.2% vs 30.4%; P = .11) in the video recorded group.
No randomization, confounding of intervention effects, and sample size limitations.
Video recording of colonoscopies is associated with a nonsignificant increase in the ADR and a significant increase in the hyperplastic polyp detection rate. There may be a benefit of video recording for endoscopists with low ADRs.
腺瘤检出率（ADR）是结肠镜检查的质量基准，受多种因素影响，包括肠道准备、退出时间和退出技术。
评估所有结肠镜检查录像对 ADR 的影响。
比较实施录像前后两组接受结肠镜检查的患者。
学术门诊内镜设施。
本研究纳入了接受筛查性结肠镜检查的无症状、平均风险的成年人。
所有结肠镜检查程序的录像。记录了 208 例连续筛查性结肠镜检查的息肉发现和退出时间。随后实施并向工作人员宣布了所有结肠镜检查录像的政策。随后收集了另外 213 例筛查性结肠镜检查的数据。
腺瘤检出率、退出时间、高级息肉检出率、增生性息肉检出率。
录像后，38.5%的患者至少检出一个腺瘤，而录像前为 33.7%（P =.31）。增生性息肉检出率显著升高（44.1%比 34.6%；P =.046）。大多数内镜医生的 ADR 数值有所增加，但只有一位显著增加（57.7%比 22.6%；P <.01）。录像组中，直径<5mm 的腺瘤（59.1%比 52%；P =.23）和右侧腺瘤（40.2%比 30.4%；P =.11）的检出率呈上升趋势。
无随机分组、混杂干预效果和样本量限制。
结肠镜检查录像与 ADR 的无显著增加和增生性息肉检出率的显著增加相关。录像可能对 ADR 较低的内镜医生有益。
