BACKGROUND/AIMS: The aim of this study was to assess the effects of endoscopy nurse participation on polyp detection rate (PDR) and adenoma detection rate (ADR) of second-year fellows during screening colonoscopies.
This was a single-center, prospective, randomized study comparing a fellow alone and a fellow plus an endoscopy nurse as an additional observer during afternoon outpatient screening colonoscopies. The primary end points were PDR and ADR.
One hundred ninety-one colonoscopies performed by a fellow alone and 192 colonoscopies performed by a fellow plus an endoscopy nurse were analyzed. The PDR was significantly higher when the nurse was involved (53.1% vs. 41.3%, p<0.05); however, there was no significant difference in the ADR between the two groups (38.5% vs. 29.8%, p=0.073). There was no difference in the percentage of patients with ≥2 polyps, advanced adenomas, polyp size, polyp location, and polyp shapes between the two groups. There was no difference in the PDR according to the level of experience of the endoscopy nurse.
Endoscopy nurse participation as an additional observer during screening colonoscopy performed by second-year fellow increases the PDR; however, the level of experience of the nurse was not an important factor.
背景/目的：本研究旨在评估内镜护士参与对第二年住院医师行筛查性结肠镜检查时息肉检出率（PDR）和腺瘤检出率（ADR）的影响。
这是一项单中心、前瞻性、随机研究，比较了第二年住院医师单独进行和在下午门诊筛查性结肠镜检查中增加一名内镜护士作为额外观察者时的情况。主要终点是 PDR 和 ADR。
分析了由一名住院医师单独进行的 191 例结肠镜检查和由一名住院医师加一名内镜护士进行的 192 例结肠镜检查。当护士参与时，PDR 显著升高（53.1% vs. 41.3%，p<0.05）；然而，两组之间的 ADR 没有显著差异（38.5% vs. 29.8%，p=0.073）。两组之间患者的≥2 个息肉、高级别腺瘤、息肉大小、息肉位置和息肉形状的比例没有差异。护士的经验水平与 PDR 没有差异。
内镜护士作为额外观察者参与第二年住院医师进行的筛查性结肠镜检查可提高 PDR；然而，护士的经验水平不是一个重要因素。
