[Radiographic and endoscopic diagnosis of gastric cancers in the esophago-gastric region].

The basic study for x-ray diagnosis and endoscopic one of early gastric cancer in the cardiac region was made. 30 cases of early gastric cancer were investigated for this purpose. The half-standing prone right anterior oblique projection and the half-standing supine left anterior oblique one were indispensable in routine x-ray examinations to detect the early gastric cancer in the cardiac region. Such findings as irregularly shaped barium fleck or irregular collection of the barium with faint granularity should carefully be checked up in terms of x-ray diagnosis of early gastric cancers in the cardiac region. Such findings as reddish discoloration and mucosal unevenness should carefully be checked up in terms of endoscopic diagnosis of early gastric cancers in the cardiac region.
