[Potentialities of ultrasound study in diagnosis of endophytic carcinoma of stomach].

The data of studies of 45 patients with gastric cancer are used to consider the potentialities of ultrasonography (USG) in the diagnosis of its endophytic forms. Its use in the diagnosis of "small" gastric carcinomas is evaluated. The USG semiotics of endophytic tumors of the stomach, including its "small" and early forms, is presented. The place of USG in the diagnostic algorithmic of gastric cancer is specified. In the authors' opinion, gastric USG along with traditional X-ray and endoscopic studies should take an appropriate place as it is beneficial in solving a great deal of differential diagnostic problems associated with the intramural spread of tumors.
