摘要 目的探讨MSCT在直肠癌术前保肛评估中的应用价值。方法对130例拟接受外科手术治疗的直肠癌患者于术前行MSCT平扫及三期动态增强扫描。术前评估可保肛的标准包括肿瘤下缘至肛提肌的距离≥1cm、直肠周围脏器未受侵、直肠周围无广泛淋巴结及癌结节转移。以手术结果为标准,评价MSCT直肠癌术前保肛评估的效能。并对MSCT术前评估与手术结果的一致性进行分析。结果 MSCT术前保肛评估的敏感度为94.12%(96/102),特异度为57.14%(16/28),准确率为86.15%(112/130),阳性预测值为88.89%(96/108),阴性预测值为72.73%(16/22)。MSCT术前评估与手术结果具有较好的一致性(Kappa=0.57,P<0.05)。结论 MSCT直肠癌术前保肛评估具有较高的准确率。 Objective To investigate the application value of MSCT in preoperative evaluation of anus-preserving in rectal carcinoma patients.Methods A total of 130 patients with rectal carcinoma were enrolled.Surgical operation was the planed treatment.All the patients underwent preoperative plain and triphasic dynamic contrast enhanced MSCT.MSCT preoperative assessment standard of anus-preserving included the distance from the tumor to anal verge≥1cm,and without surrounding organs invaded and local lymph nodes metastasis by rectal carcinoma.Taking the results of surgical operation,the diagnostic efficiency of preoperative evaluation using MSCT was studied.And the consistency analysis between MSCT and surgical operation results was performed.Results The sensitivity,specificity,accuracy,positive predictive value and negative predictive value of MSCT preoperative evaluation of anus-preserving was 94.12%(96/102),57.14%(16/28),86.15%(112/130),88.89%(96/108) and 72.73%(16/22),respectively.Preoperative evaluation outcome of anus-preserving using MSCT was mainly consistent with surgical operation(Kappa=0.57,P0.05).Conclusion MSCT can be used in preoperative evaluation of anus-preserving for rectal carcinoma patients with high accuracy.
