Abstract
We studied combined gastric and duodenal ulcers grouping the cases in radiological and endoscopical diagnosis, and obtained the results below. In the total ulcers, the incidence of the combined ulcer was 9.4% in the cases of radiological diagnosis and 13.1% in the cases of endoscopical diagnosis. The latter was higher than the former. It was considered that the duodenofiberscopy was used in patients who have some abnormal findings in duodenum, pancreas and bile duct radiologically. The number of the male was more than the female. The proportin of the male to the famale was 5 to 1. At the first examination, the one both gastric and duodenal ulcers were fresh was most frequent in the cases of radiological and endoscopical diagnosis. In the cases which were observed the process, as compared with gastric ulcer and duodenal ulcer in combined ulcers, recurrent cases were same numbers, but duodenal ulcers were more in cured cases. The bulbus of duodenum make a stenosis by scarred healing. In duodenal ulcer proceeding cases, the one which has clear stenosis was only one case in the cases of radiological and endoscopical diagnosis. So, the stenosis does not appear to be a major factor in the pathogenesis of combined ulcers. In atrophic gastritis of com-bined ulcers, the one both gastric and duodenal ulcer were scarred was most frequent. In endoscopical diagnosis, the combination of gastric angle and the anterior wall of duodenal bulbus was most frequent. Adding advanced endoscopic examination to X-ray studies, we should examine coexistent ulcers more exactly and should clear the true form more minutely.
