To describe factors that may influence adenoma detection rate (ADR), with an emphasis on the indication for colonoscopy.
Consecutive colonoscopies performed by a single endoscopist between January 2008 and December 2014 were reviewed. Indications for colonoscopy were tested for association with ADR after adjusting for age and sex.
A total of 2648 colonoscopies were analyzed. Adenomas were detected in 630 patients (23.8%). Overall ADR was 22.9% in patients undergoing screening colonoscopy. ADR was higher in fecal occult blood test-triggered screening colonoscopies (32%) than colonoscopies performed for patients with a family history of colorectal cancer (21.7%) or asymptomatic average-risk individuals (20.4%) (P=0.05). ADR was 36.1% in patients undergoing surveillance colonoscopy and ranged from 12% to 30% in patients with gastrointestinal symptoms undergoing diagnostic colonoscopy.
ADR differs depending on whether the indication is screening, surveillance, or diagnosis. Within screening colonoscopies, ADR seems to be higher in patients with a positive fecal occult blood test.
描述可能影响腺瘤检出率（ADR）的因素，重点关注结肠镜检查的适应证。
回顾了2008年1月至2014年12月期间由一名内镜医师连续进行的结肠镜检查。在对年龄和性别进行校正后，对结肠镜检查的适应证与ADR之间的关联进行了测试。
共分析了2648例结肠镜检查。630例患者（23.8%）检测到腺瘤。接受筛查结肠镜检查的患者总体ADR为22.9%。粪便潜血试验触发的筛查结肠镜检查的ADR（32%）高于为有结直肠癌家族史的患者（21.7%）或无症状平均风险个体（20.4%）进行的结肠镜检查（P=0.05）。接受监测结肠镜检查的患者ADR为36.1%，接受诊断性结肠镜检查的有胃肠道症状的患者ADR在12%至30%之间。
ADR因适应证是筛查、监测还是诊断而有所不同。在筛查结肠镜检查中，粪便潜血试验阳性的患者ADR似乎更高。
