Gastroenteroscopy in Japan is actually done using endoscopy. An endoscope is a tube equipped with a light, which can enter the stomach through the mouth or other natural orifices into the body, and can be used to see lesions that cannot be shown by X-rays, and with the help of endoscopy the doctor can observe ulcers or tumors in the stomach, and accordingly formulate an optimal treatment plan, which can be said to be very useful to the doctor,. In the physical examination, it is usually used to do gastroscopy or enteroscopy.
Gastroscope Gastroscope, with the help of a thin, soft tube into the stomach, the doctor can directly observe the esophagus, stomach, duodenum internal situation, especially for small and early lesions have the most intuitive judgment.
The front end of the gastroscope tube is equipped with an endoscope, which emits a strong light from a light source, and turns it through an optical fiber, allowing the doctor to clearly observe the condition of various parts of the upper gastrointestinal tract from the display screen at the other end. If necessary, a clip can be inserted through a small hole in the gastroscope to take cell sections for examination (biopsy).
Gastroscopy using endoscopes
The commonly used gastroscopy equipment within China is the oral-entry type, where the diameter of the gastroscope hose is thicker and passes through a sensitive part of the throat, which tends to produce a feeling of vomiting and makes many people fearful of gastroscopy. Many examiners will choose the painless method of general anesthesia, but anesthetics, after all, have damage to the human nervous system.
Gastroscopy in fact, the examination, as long as the relaxation, correct and rhythmic whistle can be effective in relieving the discomfort, for the gastroscopy of the way, role and benefits of sufficient understanding, effective cognition can eliminate a lot of psychological anxiety and pain.

Japan is the first country in the world to invent and use medical endoscopy technology, and at present, gastroscopes for medical checkups in Japan have been used with nasal-entry equipment, with a thinner endoscopic tube that is slightly thinner than a pinky thumb.
Doctors debugging equipment before a colonoscopy
No food is allowed for eight hours before a gastroscopy. The examination was preceded by a cup of medicated water used to eliminate air bubbles in the stomach, and then some drops of medication to help ventilation in the nasal cavity, choosing the side that is more open to drops of anesthetic solution, which will flow down the nostrils into the mouth, and which needs to be swallowed to reduce the sensitive reaction of the throat, so that it won't be difficult to put in the endoscopic tube afterwards.
The gastroscopy doctor will slowly put the endoscopic tube into the nasal cavity, and then go deeper into the esophagus and stomach, he will put the endoscope into the deepest part of the duodenum first, and then slowly check from deep to shallow.
Overall, the inside of the digestive tract should be smooth. If a foreign object is encountered, water will be sprayed through a miniature nozzle on the endoscope's head to determine whether it is something growing inside the digestive tract, such as a polyp, or undigested food sticking to the inner wall. When it is not clear, iodine will also be sprayed for staining, and if any problems are found, the doctor will use the head micro device to take a sample, which will subsequently be examined by laboratory tests. The whole process is about 20-30 minutes or so, the endoscope will take a lot of photos so that when the second observation to confirm.
