目的 探讨CT仿真内镜(CT virtual endoscopy,CTVE)在低位直肠癌术前分期中的价值。
方法 收集我院2008年8月1日至2011年3月1日期间的直肠癌患者57例,术前行直肠CTVE检查,详细记录患者直肠癌周围组织浸润和淋巴结转移的情况;患者术后常规进行病理检查,比较两者结果的差异。
结果 术前直肠CTVE检查与术后石蜡病理检查对直肠癌周围淋巴结转移的判断经四格表χ2检验,差异无统计学意义(χ2=2.5,P>0.05),其对直肠癌周围淋巴结转移预测的敏感性为66.67%,特异性为93.94%。术前直肠CTVE预测直肠癌周围组织浸润和术后病理检查结果经四格表χ2检验,差异有统计学意义(χ2=4.4,P<0.05),其对直肠癌周围组织浸润判断的敏感性为27.78%,特异性为42.86%。
结论 CTVE在术前评估直肠癌周围淋巴结转移有较高的可信性,但对直肠癌周围组织浸润的评价较差。
