[Gastric carcinoma--the sentinel node concept: initial experience].

Gastric cancer is a serious malignant disease. The only hope for long time survival is radical surgery. It consists of gastrectomy and also resection of adjacent lymphatic tissues. The extent of lymphadenectomy is one of the currently discussed questions. D2 lymphadenectomy is now becoming standard also in our country. This extensive procedure can be quite difficult and needs an experienced surgeon. It is also connected with prolonged operation time and higher costs. According to some authors, this procedure is also associated with a higher morbidity. The question, whether D2 lymphadenectomy should be performed, could be answered by the sentinel node concept, which is the topic of our work.
