Materials and Purpose:
Comparing the x-ray findings of 63 lesions in 58 cases of early gastric cancer with those of 105 cases for control experiment, I have studied x-ray diagnosis of early gastric cancer, especially of superficial types of early gastric cancer. The technique in detecting early gastric cancer, the interpretation of films, the diagnostic ability of x-ray examination, the limitations of x-ray diagnosis and the differential diagnosis were investigated.
Results:
1) In order to find a lesion of superficial, elevated type, compression which belongs to our fluoroscopic table can satisfactorily demonstrate a lesion up to 2 cm. in diameter.
2) For the purpose of detecting a superficial, depressed type, it is the best to use the double contrast method effectively. To get satisfactory radiographic details with double contrast method the stomach of the patient should be distended moderately with an adequate amount of air.
3) A lesion of superficial, depressed type larger than 4 cm. is easily detected with the double contrast method. In detecting a lesion of superficial, depressed type with the size of 2 to 4 cm. in diameter a strict taking of films and a strict interpretation of films should be required. The double contrast method which is effectively performed can clearly demonstrate the findings of the central part of the lesion and the gastric mucosa surrounding the lesion.
4) The double contrast method in the prone position is not only indispensable but very effective to find a lesion on the anterior gastric wall.
5) Supplemental endoscopic examination is needed in order to find a small early cancers and early cancers on the anterior wall of the stomach.
6) All kinds of lesions which have to be differentiated roentgenologically from early gastric cancer have been noted. When we encounter the x-ray findings that suggest an early gastric cancer hereafter, we have to deal with these x-ray findings considering the lesion which have to be differentiated from early gastric cancer.
