[Sonography in the diagnosis of lymphogranulomatosis].

With a rate of 87.7% of exact diagnoses, sonography is a proven method to find intraperitoneal and retroperitoneal manifestations of malignant system diseases. It is not stressing or invasive and can be frequently repeated; needing less expenditure and involving no risks, it can bear comparison with lymphographic methods and is important in the classification of stages of lymphatic system diseases. During one examination, enlarged organs and infiltrations in form of focuses in the parenchymatous organs can be diagnosed, and vessels and formations of lymphomas can be seen within their topographic connection. Independently from their drainage ways, all enlarged lymph nodes, also those situated in areas not accessible by lymphography like the hilus of liver, spleen, kidney, and retrohepatic, mesenteric, and intraperitoneal regions, can be visualized even without administration of a contrast medium. The method offers the possibility of frequent control examinations during radiotherapy or chemotherapy; possible recurrences can be early detected. However, manifestations of a malignant system disease in the lymph nodes can be hardly discerned from metastases of a primary tumor localized in another region. Despite this disadvantage, sonography keeps the first rank in the gradual application of image-producing diagnostic methods (sonography, CT, lymphography).

[Extensive lymphadenectomy in gastrectomy and gastric resection in cancer].

When using routine methods of lymphadenectomy the excisable parietal groups of lymph nodes are left intact. This is considered to be an unjustified ground for refusal of a curative operation for gastric cancer Metastases to lymph nodes of these groups are frequently found in gastric cancer. The authors recommend to use extensive lymphadenectomy when the removed preparation includes the lymph nodes of parietal groups. It was shown that the degree of the operative risk did not increase in this case. Five year survival was achieved in certain patients having metastases to lymph nodes of parietal groups.
