抄録

Clinical and histopathological studies were made on 39 cases of erosive gastritis among the 227 cases of resected stomach specimen of benign ulcer.
The results are as follows:
1) Erosive gastritis accompaning ulcer was observed in 17.2%. Highest incidence was observed in gastroduodenal ulcer, followed by duodenal ulcer, gastric ulcer respectively.
2) Erosive gastritis was more common in the male and most of the cases were the patients. between the age of 20 to 60.
3) Commonest complaint of the patient with erosive gastritis was abdominal pain. Bleeding was approximately 10%. Duration of complaint was about 6 months in average.
4) Examining occult blood, the positive rate was greater in the erosive gastritis with ulcer in comparison to the control.
5) Most of the cases of erosive gastritis showed hyperacidity of gastric juice.
6) Macroscopical observation revealed that most of the cases were diffuse protruded verioliform type and no cases of mixed type (protruded and excavated) were present. An exceptional case demonstrated diffuse protruded lesion on all over the mucosal surface from cardia to pylorus. Sometimes it is difficult to differentiate erosive gastritis from early stomach cancer and careful caution is necessary to establish the diagnosis.
7) Histologically, atrophy of pyloric gland and intestinal metaplasia is less common in erosive gasgritis. Lymphfollicular hyperplasia was observed in some degree.
8) It can be considered that erosive gastritis may appear during the course of mucosal atrophy. Repeated changes between erosion and regeneration may finally produce high grade of mucosal atrophy.
