A gastric ulcer is one of the diseases which show various developments. And also, it is, in many cases, difficult to presume what progresses it would make. It needs medical or surgical treatments, and therefore, many discussions exist concerning with gastric ulcers as interdisciplinary subjects. The author of this paper has made this study from the viewpoint that it is, to some degree, possible to presume what kind of progress a gastric ulcer would make in its prognostic developments, including the progresses after the niche has disappeared, from the radiographs taken at the first detection of the gastric ulcer. As the subjects of my study, I have made all of macroscopic, pathohistological and radiological investigations of 225 resected specimens, 299 gastric ulcers, and radiological fallow-ups of the progresses of of 182 subjects, 192 gastric ulcers. I have had the results to be concluded like the following: 1. In most of the ulcers (the healed ulcers) which show more than five findings, the finding-group A as defined by the author, the disappearance of the niches can be recognized. The duration needed for the disappearance of the niches is, in many cases, less than four months. The radiographs taken at the time of disappearance of the niche do not show, in many cases, remarkable converging folds nor the barium fleck. The recrudescence of a niche is, most of the cases, unrecognized in the follow-ups for more than six months after the disappearance of the first niche. 2. The ulcers (the non-healed ulcers) which show more than five findings, the findings, the finding-group B as defined by the author, show constancy in size in some cases, or repeat retrenchment and enlargement, or show morphological changes into linear shapes and progress as linear ulcers. We cannot expect the disappearance of the niches in these cases. 3. Of the ulcers which belong neither to finding-group A, the healed ulcers, nor to finding-group B, the non-healed ulcers, and which I call here "an in-between group", it needs, in most cases, more than four months of duration until the niche disappears. The radiographs of this group taken at the time of disappearance of the niches show to a considerable degree the convergence of the mucosal folds and the barium flecks. And also, follow-up examinations for more than six months after the disappearance of the niches reveal recrudescence of niches in most of the cases. Therefore, the diagnosis of the prognostic developments of the "in-between group" ulcers can be made easier by considering the duration needed for the disappearance of the niche and by referring to the radiographs taken at the time of disappearance.
