In our routine X-ray examinations of the stomach we do no longer encounter much difficulty in the diagnosis of the case. By virtue of a marked improvement of the X-ray instruments as well as by a great advance in techniques of the diagnosis we now can use endoscope, fibrinoscope, cytological examinations among others that our diagnosis is betting more and more accurate, as revealed by many reports. Nonetheless, the difficulty we encounter in our X-ray diagnosis is in those cases with contracture or deformation in the pyloric antrum. Of course, in the cases with malignant pathological changes or ulcers, we face relatively less problems, but in those cases with various pathological changes on the mucous coat such as an irregular relief, a partial hypertropy or lacking in any definite finding, we find it difficult to decide whether such changes have been elicited by gastritis or other causes. We discussed about how we might handle when we meet such cases with contracture of the pyloric antrum.
