 A macroscopic (visible) diagnosis and related examination in screening for gastric cancer by endoscopy without biopsy were analyzed in 246 lesions in 219 cases. The rates of correct macroscopic diagnosis were 71.0%and 95.5%in superficial and non-superficial carcinoma, respectively. The rates of correct diagnosis and detection of cancer were high, and the results of visible diagnosis were good that did not use antispasmodic agents. Diagnostic errors occurred more frequently in the area of lesser curvature and lower gastric body, and were detected at high rates in the cases of well-differentiated, type of early gastric cancer with a central depression. The outcome of endoscopic examination was compared with X-ray examination in 62 lesions. The results indicated that lesions 8 mm or less in diameter were difficult to depict, and those measuring 8-16 mm were difficult to characterize. Therefore, macroscopic diagnosis by endoscopy was more useful in screening for gastric cancer in cases with lesions measuring 16 mm or less as compared to X-ray examination.
