Which is better, ordinary gastroscope or painless gastroscope?

Disease analysis: Hello, both methods have their advantages and disadvantages. Ordinary gastroscope has no anesthesia risk, but the process will be more painful. It is likely that the patient can't bear to stop the examination and treatment, and it is easy to damage the digestive tract mucosa. Painless gastroscope adopts general anesthesia, and patients have no pain, but they need to bear the risk of anesthesia. Now most of them are painless gastroscopes. Suggestion: Gastric polyp must be removed, because it may become malignant, so it is generally recommended to remove it. You can choose which gastroscope to use according to my analysis above.
