Abstract：Objective To investigate the value of TRUS (Transrectal Ultrasonography) with annular 360 array
probes in the preoperative TN staging of rectal carcinoma. Methods Sixty cases of clinically-diagnosed
rectal carcinoma were staged pre-operatively by TRUS with annular 360 array probes and compared with
postoperative pathological staging respectively. Results The overall accuracy ratio of TRUS with annular
array probes was 75% (45/60). The accuracy of TRUS for PT1, PT2, PT3 and PT4 tumors was 84.6% (11/13),
70.1% (12/17), 70.0% (14/20) and 80% (8/10) respectively. The sensitivity, specificity and accuracy of TRUS
in lymph node metastasis were 74% (20/27), 76% (25/33) and 75% (45/60) respectively. Conclusion As
an effective pre-operative diagnosis method, TRUS with annular array probes demonstrated its accuracy in
preoperative staging of the rectal carcinoma, which offered important evidences for clinical diagnosis and
treatment of the rectal carcinoma.
