 Usefulness of a contrast method which is routinely applied with our endoscopy in the diagnosis of early gastric cancer was studied. 49.7% of early cancers at our hospital were lesions under 20mm in size. 71.6% of early cancers had mucosal invasion. 86.4% of these early cancers were diagnosed correctly or as suspicious lesions. Only 3.6% of the lesions were overlooked. These results suggest that our contrast method was more useful in the detection of the smaller and earlier lesions than conventional endoscopy.

 After reviewing many reports of pathological studies on cases concerning resected early gastric cancer, it is clear that lesions without lymph node metastasis are as follows; mucosal cancer of I and Ⅱa type, within 20mm in size, and Ⅱc type within 10mm in size, and those lesions without ulcer or ulcer scar. It is possible to treat such lesions by therapeutic endoscopy. The conclusion is that we should aim at the detection of these early-stage cancers. For carrying out this aim, it is desirable to apply the contrast method from the first endoscopic examination.
