| 摘 要： | 目的 观察螺旋CT检查在术前预测进展期直肠癌环周切缘受累的准确性.方法 39例病理证实直肠癌病人,以空气作为肠腔内对比剂进行螺旋CT扫描,按全直肠系膜切除术原则进行手术,将CT扫描与病理组织学检查结果 进行比较.结果 螺旋CT准确判断出肿瘤在直肠系膜间隙内侵犯的深度.8例环周切缘阳性的病人均可见直肠系膜内明显的肿瘤浸润,7例病人通过螺旋CT准确判断出环周切缘受累.预测环周切缘受累灵敏度为87.5%(7/8),特异度为93.3%(29/31),准确度为92.3%(36/39),阳性预测值为77.8%(7/9),阴性预测值为96.7%(29/30).结论 术前螺旋CT检查可准确预测肿瘤环周切缘状态.

| Abstract: | Objective To evaluate the accuracy of multi-slice spiral computed tomography(SCT) imaging in preoperative prediction of circumferential resection margin(CRM) involvement in advanced rectal cancer. Methods Preoperative SCT was performed with air as contrast medium in 39 patients with rectal cancer confirmed pathologically,and the operation carried out based on total mesorectal resection(TME) principle.CT images were compared with histopathologic sections. Results The depth intruded by the tumor in mesorectal... |
