摘要
目的探讨多排螺旋CT仿真结肠镜(CT virtual colonoscopy,CTVC)对结直肠占位诊断的临床价值。方法41例经结肠镜诊断为结肠占位的患者,经肛门注气后行16排螺旋CT腹盆腔连续薄层扫描,应用多排螺旋CT仿真结肠镜软件对获取的数据进行三维仿真结肠镜图像重建,与结肠镜和临床病理结果进行对照分析。结果结肠镜诊断结肠息肉12例共21枚息肉,仿真结肠镜发现10例共15枚息肉;结肠镜诊断结肠癌29例,仿真结肠镜诊断结肠癌27例,并发现2例肝转移,1例腹膜后淋巴结转移。结论CTVC对结肠占位性病变是一种无创、有效的检查方法,它不仅可以显示结肠占位的部位、大小,而且还可以显示结肠壁及结肠外的转移情况,对结肠癌的临床分期和手术方案的选择具有重要意义。
Objective To study the value of multi-slice spiral CT virtual colonoscopy （CTVC） in diagnosing colorectal neoplasms. Methods Forty-one patients with colorectal neoplasms proven by colonoscopy were further scanned successively by a 16-slice spiral CT with thin-section after intra-anal air insufflation. Then the data were 3D reconstructed simulating in virtual endoscopy and the results were compared with what seen with the conventional colonoscopy and the clinic pathological findings. Results A total of 21 polyps in 12 patients were discovered by colonoscopy, while 15 polyps in 10 patients by CTVC. In addition, 29 cases of colorectal cancer were diagnosed by colonoscopy, and 27 cases of colorectal cancer were discovered by CTVC. Besides, two cases of liver metastasis and one case of lymph node metastasis in posterior peritoneal cavity were demonstrated in colonic cancer by CTVC. Conclusion CTVC is a non-invasive and valid technique for colonic occupying lesion, which can demonstrate not only the location and the size of colorectal neoplasms, but also the invasive depth and extracolonic metastasis. CTVC has an important value in clinical stage and choice of surgery for colorectal cancer.
