Abstract:
Objective To evaluate the role of transrectal ultrasonography (TRUS) in preoperative evaluation of the depth of invasion in rectal carcinoma.Methods Fifty-eight cases with rectal carcinoma confirmed by pathology underwent TRUS before surgery.Preoperative staging was performed using the T staging system on the basis of TRUS sonogram.The T staging results by TRUS were compared with those of postoperative pathologic staging.Results The preoperative overall accuracy rate of TRUS was 82.76％ (48/58).The diagnostic accuracy rates in T1-T4 stage by TRUS were 94.83％(55/58),86.21％(50/58),86.21％ (50/58) and 98.28％ (57/58).Staging rectal carcinoma with TRUS showed better consistency with postoperative pathologic staging.Conclusions TRUS has a better accuracy in preoperative evaluation of the depth of invasion in rectal carcinoma.TRUS is an important factor in rational treatment.
