Painless gastroscopy is usually performed without nausea and other uncomfortable symptoms, so from the experience of using it is better than ordinary gastroscopy, but the diagnostic effect of the two diseases is the same. In general, compared with ordinary gastroscopy, painless gastroscopy requires intravenous anesthesia, after which the patient can lose consciousness, which is conducive to the entry of the gastroscope, and at the same time, the patient will not experience nausea and other discomforts. Therefore, for patients, the experience of painless gastroscopy is superior to that of ordinary gastroscopy. However, painless gastroscopy carries a higher risk and has higher requirements for patients’ age and past medical history. Both plain and painless gastroscopy can smoothly visualize the esophagus, stomach and duodenal bulbous descent, and their diagnostic and therapeutic effects are consistent. The choice of ordinary gastroscopy or painless gastroscopy should be decided by a professional doctor according to the patient’s specific situation, do not make blind judgment on your own.
