Transrectal ultrasound (TRUS) was performed preoperatively in 32 patients with rectal carcinoma. Compared with the Duke's classification modified by Astler-Coller, TRUS correctly staged 30/32 patients (accuracy, 93.7%); 1 was understaged and 1 overstaged. In perirectal fat infiltration, accuracy was 96% (25/26). 21 out of 32 patients undergoing anterior resection, were stadied with TRUS and transvaginal altrasound (TVUS) at 6-24 months after surgery. Recurrent local tumour developed in 2 out of 22 patients; in each case, TRUS and TVUS identified recurrence, histologically confirmed. This study demonstrates that TRUS is accurate in preoperative 'T' staging of rectal carcinoma. TRUS and TVUS may be employed in the follow-up for detection of local recurrence.

Abstract
Transrectal ultrasound (TRUS) was performed preoperatively in 32 patients with rectal carcinoma. Compared with the Duke's classification modified by Astler-Coller, TRUS correctly staged 30/32 patients (accuracy, 93.7%); 1 was understaged and 1 overstaged. In perirectal fat infiltration, accuracy was 96% (25/26). 21 out of 32 patients undergoing anterior resection, were stadied with TRUS and transvaginal altrasound (TVUS) at 6-24 months after surgery. Recurrent local tumour developed in 2 out of 22 patients; in each case, TRUS and TVUS identified recurrence, histologically confirmed. This study demonstrates that TRUS is accurate in preoperative 'T' staging of rectal carcinoma. TRUS and TVUS may be employed in the follow-up for detection of local recurrence.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
