Abstract:
Objective To compare the efficacy of transrectal ultrasonography(TRUS)and spiral computed tomography(SCT)in preoperative staging of rectal carcinoma contrasted with the postoperative pathologic findings.Methods Both TRUS and SCT were performed prior to surgery in 92 patients with rectal carcinoma.After radical operation,the preoperative findings were compared with the histological findings,and the the efficacy of TRUS and SCT in staging the rectal carcinoma were evaluated.Results The accuracy of TRUS for T stage and N stage was 87.0% and 64.1% respectively,while the accuracy of SCT was 68.5% and 66.3%.Conclusions TRUS is superior to SCT for the judgment of tumor infiltration depth,TRUS may become the first choice in preoperative staging of rectal carcinoma.But neither is able to provide satisfaction assessment for lymph node metastases.When both methods are used together,it would be better.
