Painless gastroscopy – the new trend of gastroscopy With the change of lifestyle and living environment, the number of patients suffering from esophageal and stomach diseases is gradually increasing. For upper gastrointestinal disorders, the most intuitive and effective way to examine them is gastroscopy. In the past, the painful reaction to gastroscopy often discouraged patients and made them afraid of the test, missing the best time for diagnosis and treatment. Even if the patient reluctantly underwent the examination, the painful sensation was haunting. Now, using the new technology of painless gastroscopy diagnosis and treatment, patients can safely undergo gastroscopy in a short sleep state without any discomfort and adverse sequelae, reducing the mechanical damage caused by unconscious agitation of patients due to pain, and avoiding the organic effects of breath-holding, blood pressure and heart rate changes caused by stimulation of the vegetative nerves. It makes many diseases that need surgical treatment can be treated under gastroscopy. This saves the pain of surgery, saves medical expenses and shortens the treatment time. Precautions for painless gastroscopy Firstly, patients should overcome their fears and consult with gastroenterologists or gastroscopy operators if they have any questions. Secondly, two days before gastroscopy, you should reduce food and stop all transoral medications appropriately. The day before the examination, fasting milk, preferably soft liquid food, the morning of the examination should be fasting, abstaining from water, all drugs and smoking. After the examination, it is best to eat less stimulating food. After two hours, you can eat liquid food. For example, chicken cake, milk, noodles, rice porridge, etc. During the examination, the esophageal mucosa and gastric mucosa are mechanically and transiently stimulated, and the swelling and pain in the throat and discomfort in the stomach and stomach occur momentarily and mechanically and transiently stimulated, and the swelling and pain in the throat and discomfort in the stomach and stomach occur momentarily and vaguely, so smoking, alcohol and overheated food should be abstained. It is not advisable to do excessive physical work, and rest should be taken for 1 – 2 days. Painless gastroscopy is not recommended for the following patients, such as those of advanced age (age >70 years), suffering from obvious heart and lung diseases, mental diseases, etc. Four advantages of painless gastroscopy Painless: Patients do not feel any discomfort during the examination and treatment, and painless gastroscopy is an ideal choice for patients who are nervous or afraid of gastroscopy. Less invasive: Under painless electronic gastroscopy, several minimally invasive treatments can also be performed for gastrointestinal bleeding, polyps and ulcer stenosis, saving patients from the pain of surgical incision. Short time: excluding the preparation time before the examination, it can be completed in a few minutes from the beginning of the examination. More accurate: electronic gastroscopy has the advantage that other examination means cannot replace at present, especially some tiny lesions and even lesions of mucosal layer can be clearly diagnosed. And it has the function of magnification, which further increases the accuracy of diagnosis. At present, painless gastroscopy has gradually been accepted and widely popularized. In some large hospitals such as the General Hospital of the People’s Liberation Army (301 Hospital), the proportion of painless gastroscopy patients in the endoscopy center is over 90% of all gastroscopy patients. Since 2003, the endoscopy unit under the Department of Gastroenterology of Beijing Yanhua Hospital has been the first to carry out painless gastroscopy in the southwest region of Beijing, and has safely operated more than 1800 cases without any obvious adverse reactions or complications, and is the only hospital in the southwest region to carry out painless gastroscopy, which is favored by patients in the southwest region. As a safe and efficient means, gastroparesis has played an increasing role in the diagnosis and treatment of upper gastrointestinal diseases, and has become a new trend in gastroscopy.
