已经证明，对于有经验的内窥镜医师，延长结肠镜撤出时间（WT; > 6 min）有利于腺瘤检出率（ADR）。然而，很少有数据可以指导受训者适当的结肠镜撤药时间。本研究的目的是确定是否有WT和ADR之间的关系，为第一年的研究员训练在colonoscopic.This是一个前瞻性研究的第一年胃肠病学研究员在一个单一的学术教学医院谁记录每个结肠镜检查的自我报告表在一个学年的过程中（2010年3月至2011年2月）。实习生的内部政策是每次结肠镜检查至少有6分钟的停药时间。一个学术医疗中心的四名一年级胃肠病学研究员完成了1,210次结肠镜检查的自我报告。平均WT为10.2 +/- A 3.4 min。聚集性息肉检出率为33.2%，聚集性ADR为22.3%。对于WT < 10 min的结肠镜检查，ADR为9.5%，对于WT >= 10 min的结肠镜检查，ADR为32.3%（p < 0.001）。当应用25%目标ADR（男性）和15%目标ADR（女性）的质量指标时，WT >= 10 min的筛查结肠镜检查（n = 676）的男女均达到了这一总发生率。如果结肠镜检查WT>= 10 min，则第一年的受训者的ADR显著更高。
It has been demonstrated that prolonged colonoscopic withdrawal times (WT; > 6 min) are beneficial for the adenoma detection rate (ADR) for experienced endoscopists. There are little data, however, to guide the appropriate colonoscopic withdrawal times for trainees. The purpose of this study was to determine whether there is a relationship between WTs and ADR for first-year fellows training in colonoscopy.This is a prospective study of first-year gastroenterology fellows at a single academic teaching hospital who documented each colonoscopy with a self-report form over the course of an academic year (March 2010 to February 2011). The internal policy for the trainees was to have at least a 6-min withdrawal time for each colonoscopy.Four first-year fellows in gastroenterology at an academic medical center completed self-reports for 1,210 colonoscopies. Mean WT was 10.2 +/- A 3.4 min. The aggregate polyp detection rate was 33.2% and the aggregate ADR was 22.3%. For colonoscopies with WT < 10 min, ADR was 9.5%, and for colonoscopies with WT >= 10 min, ADR was 32.3% (p < 0.001). When the quality indicator of 25% goal ADR for males and 15% goal ADR for females is applied, this aggregate rate is achieved for both sexes for screening colonoscopies (n = 676) with WT >= 10 min.First-year trainees had a significantly higher ADR if their colonoscopic WT is >= 10 min.
