    Abstract:
    The aim of the study was to assess the diagnostic value of transrectal ultrasonography (TRUS) in detecting the depth of tumor infiltration as well as the involvement of lymph nodes in patients with rectal carcinoma diagnosed after rectoscopy and proven by examination of the biopsy specimen. TRUS was performed on thirty-three patients with rectal carcinoma prior to surgery, the first assessment of tumor growth, and extension by pathological examination of the operative specimen. TRUS correctly assessed perirectal growth in 18 out of 22 cases proven by pathology (two understaged, accuracy 86 percent), while in 12 cases with no perirectal growth proven by pathology this method was correct in 9 cases (three overstaged, accuracy 75 percent). The results of this study indicate that TRUS, combined with endoscopy and biopsy, is a useful procedure in the preoperative staging of malignant rectal lesions and provides valuable data for the therapeutic planning of patients with rectal carcinoma.
