[Staging of rectal carcinoma by endorectal ultrasonography].

Staging of rectal carcinoma is essential for its management. 23 patients with rectal lesions were examined by endorectal ultrasonography. Of these 19 had rectal carcinoma and in 4 there was an abscess of the rectal wall, previously diagnosed by sigmoidoscopic biopsy. 10 of those with carcinoma were examined by computerized tomography as well, and 10 were operated on. In most cases the staging of rectal carcinoma by endorectal ultrasonography was accurate and compared well with the operative histological results. We conclude that endorectal ultrasonography is the method of choice for staging of rectal carcinoma prior to treatment.
