摘要
AIM： TO evaluate the diagnostic accuracy, sensitivity, specificity of contrast-enhanced computed tomographic colonography in detecting local recurrence of colorectal cancer. METHODS： From January 2000 to December 2004, 434 patients after potentially curative resection for invasive colorectal cancer were followed up for a period ranging from 20 to 55 mo. Eighty of the four hundred and thirty-four patients showing strong clinical evidence for recurring colorectal cancer during the last followup were enrolled in this study. Each patient underwent contrast-enhanced computed tomographic colonography and colonoscopy on the same day. Any lesions, biopsies, identified during the colonoscopic examination, immediate complications and the duration of the procedure were recorded. The results of contrast-enhanced computed tomographic colonography were evaluated by comparing to those of colonoscopy, surgical finding, and clinical follow-up. RESULTS： Contrast-enhanced computed tomographic colonography had a sensitivity of 100%, a specificity of 83% and an overall accuracy of 94% in detecting local recurrent colorectal cancer. CONCLUSION： Conventional colonoscopy and contrastenhanced tomographic colonography can complement each other in detecting local recurrence of colorectal cancer.
瞄准：评估诊断精确性，敏感，在检测颜色的本地复发的提高对比的计算 tomographic colonography 的特性表面的癌症。方法：从 2000 年 1 月到 2004 年 12 月， 434 个病人在以后潜在地药品为侵略颜色的切除术表面的癌症被跟随在上面为从 20 ～ 55 瞬间的经期。为复发显示出充分临床的证据的 434 个病人中的八十个在最后后续期间渲染表面的癌症在这研究被注册。每个病人在一样的天经历了提高对比的计算 tomographic colonography 和结肠镜检查。任何损害，活体检视，在 colonoscopic 期间鉴别检查，立即的复杂并发症和过程的持续时间被记录。提高对比的计算 tomographic colonography 的结果被结肠镜检查，发现的 surgical，和临床的后续比作那些评估。结果：提高对比的计算 tomographic colonography 在检测本地周期性的颜色有 100% ， 83% 的特性和 94% 的全面精确性的敏感表面的癌症。结论：常规结肠镜检查和提高对比的 tomographic colonography 能在检测颜色的本地复发补充对方表面的癌症。
