Application of MSCT in the evaluation of surgical operation for rectal cancer / 实用放射学杂志

ABSTRACT

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 treatment3 cases of transanal local excision,28 cases of Miles operation,3 cases of Hartmann operation,96 cases of Dixon.Preoperative evaluation of MSCT33 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,χ2=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.
