The advantages of magnifying gastroscopy over ordinary gastroscopy are obvious. However, due to the lack of ideal magnification of the previous magnification gastroscopy, gastrointestinal peristalsis, respiration, arterial pulsation, etc., which hindered magnification observation and lacked unified diagnostic standards, the popularization and application of magnifying gastroscopy in clinical practice was limited. With the improvement of the mechanical and optical properties of the electronic gastroscope, the magnification of the magnifying gastroscope, the image clarity and operability have been greatly improved, the new magnifying gastroscope that came out in recent years is the zoom endoscope, which can magnify 80 273 times, and the outer diameter of the soft mirror body is similar to that of the ordinary electronic gastroscope, the same gastroscope can be used for routine examination first, and the lesion can be zoomed in immediately, and the magnification observation is carried out immediately, and the gastroscope does not need to be replaced, which does not increase the pain of the patient and is convenient for the doctor to approach the observation effect of the solid microscope. The placement of a transparent cap at the front end of the magnifying gastroscope, the application of some drugs that inhibit gastrointestinal peristalsis, and the development of a bitter gastroscope are all more conducive to magnifying observation. The diagnostic criteria for early gastric cancer and its precancerous lesions under magnification gastroscopy are gradually being unified. Therefore, with the continuous progress and in-depth research, magnifying gastroscopy will play an important role in guiding biopsy, avoiding unnecessary biopsy trauma, and even directly diagnosing certain lesions that cannot be diagnosed by ordinary gastroscopy in the past and must rely on pathological examination, which will greatly improve the early diagnosis rate of early gastric cancer and its precancerous lesions.
