A large auto manufacturer screened its workers who belonged to the Pattern Makers (wood and metal workers) League of North America for colon cancer. Four-hundred nine asymptomatic workers were screened. Our group was only involved in performing most of the fiberoptic sigmoidoscopies in this study. This provided us with an opportunity to evaluate the practicality of the use of fiberoptic sigmoidoscopy for mass screening at a work place. The average extent of insertion of the sigmoidoscopy was 55 cm, and the average time required was 10 min. The prevalence of polyps was 10.76%, and only one in situ carcinoma was reported. This prevalence of both colon polyps and colon cancer is similar to that reported in other studies. Fiberoptic sigmoidoscopy is a valuable tool for mass screening of populations at risk for colon cancer. It is superior to rigid sigmoidoscopy not only in patient tolerance, but also the extent of examination and consequently the diagnostic yield.
一家大型汽车制造商对其隶属于北美制模工人工会（木工和金属工）的工人进行了结肠癌筛查。409名无症状工人接受了筛查。在这项研究中，我们团队只负责进行大部分的纤维乙状结肠镜检查。这为我们提供了一个机会，来评估在工作场所使用纤维乙状结肠镜进行大规模筛查的实用性。乙状结肠镜检查的平均插入深度为55厘米，平均所需时间为10分钟。息肉患病率为10.76%，仅报告了一例原位癌。结肠息肉和结肠癌的这种患病率与其他研究报告的相似。纤维乙状结肠镜检查是对有患结肠癌风险人群进行大规模筛查的一项有价值的工具。它不仅在患者耐受性方面优于硬式乙状结肠镜检查，而且在检查范围以及诊断率方面也更具优势。
