Abstract

Between 1961 and 1983, 1207 cases of early gastric cancer were resected at our hospital. Out of 1207, 78 lesions (6.5%) showed benign appearance ; in which were included 8 cases of the type IIb (61.5%) and 6 cases of the type III+IIc (30.0%). Such cases have been increasing year by year. From April to October in 1984, 1775 lesions were biopsied. Out of 1775, 272 lesions were diagnosed as grade C (low suspicion) and 1644 lesions as grade D (benign) Fifty three lesions (19.5%) in grade C were diagnosed as malignancy by biopsic examinations. On the other hand, in grade D only 2 lesions (0.1%) were cancerous. All were depressed type with ulcerative change. With endoscopic Congo red-methylene blue test, cancerous lesions were observed as bleeched areas. Diagnostic accuracy of early gastric cancer by this method was superior to that by the routine endoscopic examination.
