[Transrectal and transvaginal ultrasonic diagnosis of rectal cancer].

Abstract

In 48 patients with rectal carcinoma diagnostic means for ultrasound investigation USU were tested. The high quality of transrectal and transvaginal ultrasound scanning (US) facilitated a detailed evaluation. The stage of the malign tumor was correctly evaluated in 95.8% of the cases. In one case a false negative evaluation of the function of the muscular layer was given and in another inflammatory infiltration was seen as a tumour. Changes of the pararectal lymph nodes were found in 62% of the patients, of the regional lymph nodes in 5 patients (10.3%). Their metastatic status was proven with fine needle puncture aspiration biopsy (FNPAB) under sonographic and lymphographic control. In 10 patients with US-scanning the found focuses in the liver parenchyma. In 90% of the cases by aspiration biopsy the malignity was cytologically and histologically proven.
