Since the application of double Contrast method into the routine X-ray examination of the stomach, diagnosis of advanced Cancer of the stomach has become much easier. Particularly, very fine morphological changes of advanced Cancer can be well demonstrated by this method.
Therefore, diagnosis of the proximal limit of infiltration in stomach Cancer can be made very effectively, which is mostly helpful for surgeon preoperatively. With combined contrast and double contrast studies as its chief technique, to which compression technique is added, this system permits us to take so-called fine relief and read it, and discover far more minute changes than those caught by conventional method. According to this newly established and systematized theory of diagnostics, compression technique is most useful in diagnosis of protruded or elevated lesion while double contrast studies are most effective in that of excavated or depressed lesion, Ceaseless efforts in recent years, furthermore, have gradually raised the ceiling in diagnosis and it is now possible to discover early-stage cancers of the stomach as small as less than l0m across and less than lm thick. It may be said that we have now reached the limit of diagnosis using bare eyes.
There are two main uses for X-ray diagnosis of the stomach. First, it is used for determination of the presence or absence of abnormal changes over the whole field of the stomach to disclose any lesion present in the area, the process being usually called survey or scout diagnosis. Secondly, it is used for through identification of the abnormalities discovered or suspected, the process being called qua1itative diagnosis.
We would like to emphasize that such a step-by-step accumulation of everyday experiences leads directly to correct and confident diagnosis.
