Ten cases who were precise followed up from the initial stage were studied among patients with the acute gastric ulcers of the antrum. Seven cases were males and three females. Age of the patients ranged from 14 to 73. Predominant clinical symptoms were sudden onset of epigastralgia, vomiting or hematemesis. Roentgenologic studies performed at very early stage after the onset of symptoms revealed the remarkable mucosal edema of the gastric antrum and angulus, and sometimes irregular barium flecks without distinct niches. As the time passed, faint ill-defined barium flecks gradually changed to big irregular distinct niches. Ulcers were often multiple. Enboscopic studies demonstrated mucosal edema with dark reddish hemorrhagic erosions in the antrum which changed gradually to ulcers in necrotic area, becoming fused and developing big distinct ulcers. This process took about 24 hours. Two to three weeks after the onset of symptoms (clinical signs) the ulcers gradually healed, demonstrating the obvious convergence of mucosal folds and II c-ilke pattern with mild marginal elevation. About one month after the onset of symptoms, some lesions became scarred or Ha-like pattern with granular basis of the center.
