[Ultrasonic examination and lymphography in the diagnosis of metastases of rectal cancer]. / Ul'trazvukovoe issledovanie i limfografiia v diagnostike metastazov raka priamoi kishki.

The diagnostic effectiveness of ultrasound and lymphographic investigations was assessed in 89 rectal cancer patients. Lymphography was shown to be a more informative method as it permitted the detection of metastases in 6 patients in whom USI results were negative, metastatic involvement in 2 patients, specifying the type of pathological changes of the enlarged lymph nodes in 14 patients. In a normal lymphographic picture metastatic involvement was detected in 37 cases using echography. More extended metastatic spreading was found on USI (as compared to lymphography) in one patient. The combined use of echography and lymphography improved the diagnosis of rectal cancer lymphogenous metastases.

[Diagnosis of tumors of the bladder and rectum by the method of high-resolution transvaginal echography]. / Diagnostika opukholei mochevogo puzyria i priamoi kishki metodom transvaginal'noi ékhografii vysokogo razresheniia.

Analysis of the results of high resolution transvaginal US-tomography in 32 women with malignant bladder and rectal tumors made it possible to assess the potentialities of this new method for the diagnosis of a degree of local spreading of these tumors. As compared to transabdominal echography UST proved to be more informative in tumors of the cervix, basis and anterior wall of the bladder and in calcifications on the tumor surface which were detected in 3 patients. Transvaginal US-tomography with a contrast study of the rectal walls provided good diagnostic information on a degree of local spreading of malignant rectal tumors. The transvaginal approach showed its advantages in noticeable tumor stenosis of the rectum. Tumor assessment in 3 women with stenosis was made possible owing to this method.

[Transrectal and transvaginal echography in cancer of the rectum]. / Transrektal'naia i transvaginal'naia ékhografiia pri rake priamoi kishki.

To assess the diagnostic value of ultrasonography in rectal carcinoma, the procedure was performed in 48 such cases. Stage was reliably established in the majority (95.8%) of patients. False--negative conclusion on the muscular layer integrity was made in one case and inflammatory infiltrate was misdiagnosed as cancer in another. Pararectal lymph nodes were visualized in 62% of patients whereas regional ones--in 5 (10.4%); their metastatic origin was confirmed with fine--needle aspiration biopsy and lymphography. Ultrasonic scintigraphy identified nodular lesions in the liver parenchyma in 10 cases; the malignant nature of those foci was verified in 90% by histo- and cytologic examination of samples obtained by fine--needle aspiration biopsy.
