摘　　要：目的 探讨多层螺旋CT（MSCT）在直肠癌术前手术方式评估的应用价值.方法 收集经肠镜、临床诊断为直肠癌的146例病例资料,术前进行MSCT平扫及三期动态增强扫描检查.通过MSCT术前手术方式评估与手术结果进行比较,判断MSCT术前手术方式评估的价值.结果 130例手术患者中：3例经肛门局部切除术,28例腹会阴联合直肠癌根治术（Miles术）,3例直肠切除乙状结肠造口术（Hartmann术）,96例经腹直肠癌切除术（Dixon术）.MSCT术前评估：33例行Miles术,4例行Hartmann术,88例行Dixon术,5例经肛门局部切除术.MSCT手术方式评估符合率为84.62%.MSCT术前手术方式评估与术后结果一致性较好（k=0.653、χ^2=225.352、P=0.000）.结论 MSCT在直肠癌术前手术方式评估中有较高的准确性,对于术前手术方案选择有着重要意义.Objective To study the application value of MSCT in preoperative evaluation of rectal cancer before surgery.Methods Clinical materials of 146 patients with colonoscopy and clinical proved rectal cancer were recruited.MSCT were performed with plain and triphasic dynamic contrast enhancement before surgery.The value of MSCT was evaluated by comparing the results of pre-operative evaluation with the surgical results.Results 130 cases accepted surgical treatment：3 cases of transanal local excision,28 cases of Miles operation,3 cases of Hartmann operation,96 cases of Dixon.Preoperative evaluation of MSCT：33 cases of Miles,4 cases of Hartmann,88 cases of Dixon,5 cases of local excision of the anus.The accuracy on MSCT preoperative evaluation was 84.62%. MSCT preoperative evaluation consistency was consistent with postoperative outcome（k=0.653,χ^2=225.352,P=0.000）.Conclu-sion It is high accuracy for MSCT in preoperative evaluation of rectal cancer,and it can provide important significance for preopera-tive selection of surgical procedures.
