结肠癌的高患病率和目前推荐的筛查指南的低遵从性解释了结肠癌死亡率持续高企的原因。在50岁以上无症状的患者中使用虚拟结肠镜(VC)的策略，结合光学结肠镜(OC)随访切除发现的腺瘤性息肉可能会降低结肠癌死亡率。然而，VC的筛选潜力尚未被广泛认识。自从1994年VC首次报道以来，关于其潜在好处的争论和怀疑一直在文献中频繁出现。本文综述了目前可用的筛查方法，并讨论了它们的优点和缺点。与现有的筛查方式相比，VC有许多优点，它的几个缺点可以得到缓解，因此它将成为一种有价值的筛查方式。一种策略，利用VC进行50岁以上人群筛查，使用OC筛查高危个体和VC结果阳性的人，将显著降低结肠癌死亡率。
The high prevalence of colon carcinoma combined with the low compliance of currently recommended screening guidelines explains the continued high mortality rate of colon cancer. Utilizing a strategy of virtual colonoscopy (VC) in asymptomatic patients over 50, with optical colonoscopy (OC) follow-up for removal of detected adenomatous polyps may result in lowering the colon cancer death rate. However, the screening potential of VC has not yet been widely recognized. Debates and doubts of its potential benefits have been frequently seen in the literature since VC was first reported in 1994. This article reviews the currently available screening options and discuss their advantages and drawbacks. VC has many advantages over the existing screening options and its several drawbacks can be mitigated so that it would become a valuable screening modality. A strategy that utilizes VC for population-based screening over the age of 50 and OC for screening high-risk individuals and those with positive VC findings would result in a significantly reduced rate of colon cancer deaths.
