The role of transvaginal sonography as compared with endorectal sonography in the evaluation of rectal cancer: preliminary study.

We carried out a preliminary study on the efficacy of endovaginal sonography (EVS) in the evaluation of rectal cancer. The study included 12 women with endoscopically documented rectal cancer, 10 of which were treated surgically. We found that EVS evidenced metastasized lymph nodes (7/9) and infiltration of the rectovaginal space more clearly; moreover, this technique can also be performed in cases of stenosing cancer. Endorectal sonography (ERS) evidenced infiltration of the rectal wall but was less accurate both in detecting metastasized lymph nodes (6/9) and for exploration of the rectovaginal space. We concluded that the two methods complement one another and improve ultrasonographic staging of rectal cancer.

Evaluation Studies as Topic↗

[Ultrasound studies of the portal vein system in liver tumors].

The study was carried out on a group of 21 patients with liver tumours (20 of them primary) and thrombosis of the portal venous system. Thrombosis in the left portal vein system was found in 10 patients, in the portal vein stem in 9 patients and in the portal confluence in 2 patients. In 15 patients thrombosis developed in the presence of a multicentric liver neoplasm. Proaf of the presence of a thrombus on the main portal trunk in patients with documented liver tumour contraindicates surgical or non-surgical therapeutic manoeuvres. If a thrombus is incidentally found in the portal venous system, a careful search for a tumour in the portal vein systems is imperative. In case of any suspicious modification, fine needle-aspiration should be performed.

[The value and limits of endorectal sonography in the preoperative stage classification of rectal cancer].

The article deals with the valuation of endorectal and abdominal sonography in preoperative staging of rectal carcinoma. Data processing of 40 patients suffering from tumours of the rectum examined rectoscopically, by biopsy and via sonography showed that endorectal sonography can achieve preoperative staging (T) with a sensitivity of 89%, a specificity of 100%, a positive predictive value of 89% and a negative predictive value of 100%, the overall accuracy being 81%. Identification of pararectal adenopathies can be performed with a sensitivity of 16% and a specificity of 100%. Liver metastases were determined with a sensitivity and specificity of 100%. Hence, endorectal sonography is a valuable method for preoperative staging of carcinoma of the rectum.

Adenocarcinoma↗

[Ultrasonic diagnosis of echinococcal cholangitis].

The role of sonographic examination in echinococcal cholangitis is stressed based on a clinical case. Due to perforation of the hepatic hydatid cyst into the bile ducts the clinical picture of acute cholangitis occurred, this being difficult to differentiate from that of choledochal stones. The correct diagnosis was made by sonographic examination and was confirmed intraoperatively. The importance of emergency sonographic examination in severely ill patients is stressed.

[Cystic echinococcosis of the liver--problems of ultrasound diagnosis].

The authors examined 100 patients with a total of 119 cysts of the liver. The diagnosis was subsequently confirmed via scintigraphy, radiology and laparotomy. This paper reports on a sonographic analysis of cystic echinococcosis of the liver, its sonographically demonstrable types, structures and complications and their differential diagnosis. In 58% of the cases the classical aspect of cystic echinococcosis was seen (Type A). 22.7% of the cases pointed toward a sediment within the cyst (Type B). 8.4% of the cysts were septated (Type C), whereas 6.7% had daughter cysts (Type D). However, only 4.2% of the cysts were important for differential diagnosis, since they had to be set off against other space-occupying growths on account of their solid tumorous structure.
