At the present stage use only standard visual endoscopy and a radiological method of research of a pathology of a stomach does not meet the requirements of oncologists. In spite of the fact that these techniques continue to remain base and prime in inspection of a digestive tract, the leading part in specification of character of pathology of GI tract is taken now endosonography method. A research objective: to establish endoscopic ultrasonic criteria of diagnostics indolentics and aggressive NHL of stomach.
Materials and methods: For studying of possibilities endosonography in diagnostics NHL of a stomach 46 patients have been analysed, during the period since 2005 for 2009 to all patients after videogastroscopy was carried out endoscopic scanning, and the tumour biopsy further was made.
Results: Are defined by us endosonography criteria NHL of a stomach: the tumor starts with deep layers mucous and submucosal layer, extends mainly on submucosal layer, it is marked multicentrial defeats, echoic tumors is always lowered or heteroechoic with hypo echoic inclusions. On the basis of this data by us are defined endosonography criteria various morphoimmunological variants of NHL of a stomach. Estimating possibilities endoscopic ultrasonic diagnostics it has been revealed that its diagnostic accuracy makes 87.7%. In 84.9% at use EUS it is possible to assume authentically presence lymph proliferative process of a stomach and in 94.7% endosonography will allow to exclude authentically pathological process in a stomach.
