Abstract

A new method for combining ultrasonography snd endoscopy, endoscopic ultrasonography (EUS), was developed to improve the diagnostic accuracy of ultrasound by direct image of the target lesion via the gastrointestinal lumen. EUS has the unique ability to provide clear sonographic images of the wall structure of the stomach. This capability can be ultilized in assessing the depth of cancer invasion of the stomach by identifying which layer the ultrasonographic change extends to. However, the depressed types of early gastric cancer(EGC) are often accompanied by ulcerative change in the tumor foci. And the ultrasonographic picture is also influenced by the ulcerative change.
