| 【 要旨 】 | 米国では，virtual endoscopy(VE)は大腸スクリーニング法としての応用がもっとも注目されている．しかし，診断能に関するprospective studyのほとんどは，高リスク症例を対象としたものである．また，public perceptionの調査結果に反して，実際の手技に対するtorelanceは，大腸鏡のそれに比べて優れているとはいえない．さらに大腸鏡を用いたスクリーニングと比べて費用効果に劣るなどの問題点も指摘されている．VEによる大腸スクリーニングが実用化されるには，さらなる手技の改良と手技料の低価格化，さらにスクリーニング症例を対象とした大規模な臨床試験が必要と考えられている． | |

| [ Summary ] | Virtual colonoscopy (VC) has been tested as a tool for colorectal cancer screening in the United States. In most of the prospective studies, only patients at high risk for colorectal cancer were included. Although public perception is favorable towards virtual colonoscopy, the tolerance of patients towards VC is similar to that of colonoscopy. Studies to date have suggestedless cost efficacy in using VC in comparison with using colonoscopy as a screening tool for colorectal cancer. Further improvements in technology, decreases in the cost of VC and large scale clinical trials, performed on the average risk screening population, are required to further define the role of VC in screening for colorectal cancer. | |
