多排螺旋CT检查对结直肠癌诊断的特殊价值

Multislice spiral CT examination of the special value of colorectal cancer diagnosis

目的探讨多排螺旋CT检查对结直肠癌诊断的特殊价值。方法回顾性分析笔者所在医院近4年来对均为术前进行螺旋CT检查的术后病理证实的结直肠癌患者56例,总结螺旋CT检查在结直肠癌诊断中的特殊价值,并与结肠镜、气钡双对比造影、B超等3种检查方法进行回顾性分析。结果多排螺旋CT检查与气钡双对比造影、结肠镜对病灶的发现率几乎一致,明显高于B超。多排螺旋CT检查对发现患者浆膜层受侵及腔外肿块、腹腔淋巴结转移、肝转移、腹膜转移等明显高于其他三种检查手段。并且多排螺旋CT(结直肠充气后)扫描于工作站进行三维处理后对受侵肠管范围可以进行大致测量,比较直观显示病变形态范围,为术前手术计划制定提供参考。结论多排螺旋CT检查对结直肠癌诊断具有特殊价值,应作为结直肠癌术前必备检查之一。

Objective To investigate the multi-slice spiral CT examination of the special value of colorectal cancer diagnosis.Methods Retrospective analysis of hospital after nearly four years of pathologically confirmed colorectal cancer patients（both helical CT examination before surgery） for 56 people,summed up helical CT examination in the diagnosis of colorectal cancer special value,and with colonoscopy,double contrast barium,B-ultrasonic et al.Comparison of three test results were reviewed.Results Helical CT examination with double contrast barium,colonoscopy is almost the same detection rate of lesions was significantly higher than B-ultrasonic.Multislice spiral CT examination found that serosal invasion and tumor cavity,abdominal lymph node metastasis,liver metastasis,peritoneal metastasis was significantly higher than the other three inspection methods.And multi-slice spiral CT（after inflation colorectal） scan in three-dimensional post-processing workstation,the scope of involvement can be roughly measured intestine,lesions form of visual display and compare the scope of preoperative surgical planning for the help.Conclusion multislice spiral CT examination of particular value in diagnosis of colorectal cancer,colorectal cancer before surgery should be used as one of the necessary checks.
