[Ultrasonic diagnosis of 22 gastric tumors]

A report is presented on 22 patients with advanced stomach cancer in whom echography revealed the characteristic signs ("pseudokidney", "cockade", "target", "doughnut", etc.). Though not considered wholly specific indicators of gastric neoplasm (they may be artefacts or errors of interpretation) they are helpful in the diagnosis of the stomach. Ultrasound has made it possible to identify the site (antrum and body) and spread of the cancer both locally and at a distance and only a few forms (not encountered in the present series) have presented characteristic images. Endoscopic ultrasonography and the high resolution intraoperative type offer the chance for significant progress in this diagnostic field.
