Only gastroscopy renders it possible to recognize the different forms of tumor. Through it we shall probably be forced to revise our ideas regarding the symptomatology of new growths. Much investigation is still necessary to reach determinate results.
My observations were made in 400 gastroscopic examinations performed in the Munich-Schwabing hospital. They were made with a gastroscope of my own modification. Examination with this instrument if expertly used is almost without discomfort to the patient. The technic is not easy, and much practice is necessary to apply it safely and painlessly, but the diagnostic results are so excellent that the
