РОЛЬ КОМПЛЕКСНОГО ЭНДОСКОПИЧЕСКОГО И ЭНДОСОНОГРАФИЧЕСКОГО ИССЛЕДОВАНИЯ В ДИАГНОСТИКЕ ПРОКСИМАЛЬНОГО РАКА ЖЕЛУДКА

Gastric cancer occupies the 5th place in the structure of total cancer incidence worldwide. In 2015, Russia diagnosed about 35 thousand new cases of rye. Mortality from this disease and its complications remains high. Numerous studies conducted in different countries of the world have shown that the dominant role among all anatomical forms of gastric cancer is played by endophytic tumors (more than 65% of all detected cases), which are the most difficult to diagnose. Even with the latest diagnostic tools, it is often not possible to obtain enough information to clearly speak in favor of the existence of an intra-neoplastic process. Optimization of diagnosis of gastric cancer continues to be one of the important problems of Oncology. The absence of changes in the mucous membrane, usually makes it impossible to determine the boundaries of the standard endoscopic and radiological methods. The possibilities of standard ultrasound examination of the stomach wall, and especially the esophagus wall, are also limited. The most promising in terms of complex diagnosis of intramural and lymphogenic prevalence of tumor process is the use of endoscopic ultrasound.
