Ultrasonographic diagnosis of gastric carcinoma.

Among various gastric carcinoma diagnosis including upper gastrointestinal radiography, computed tomography (CT) and angiography, scintigram using isotope, endoscoi:;e method and ultrasonography (US), the only one that gives on harm nor pain to the patient is the ultrasonography. Moreover, the US equipment has been so remarkably improved that a sufficient US diagnosis will be able to provide more useful information than others will. Recently, we performed US on 10 gastric carcinoma patients and diagnosed invasion of carcinoma into gastric wall and other organs and its lymphatic and hepatic metastasis. The information thus obtained was very useful in determining the presence of operative indication and the operational method. This fact led us to consider US the first choice of examination methods, as reported hereunder.
