The gastroscope in Qilu Hospital of Shandong University needs to be reserved in advance. Blood routine and electrocardiogram need to be tested before making an appointment. The gastroscope room decides whether it can be done according to the examination results. If you can, you can make an appointment. Gastroscopes are generally divided into two types: pain type and painless type. The pain is about four or five hundred, and the pain is about 1800. After the appointment, I'll prescribe some medicine for clearing your stomach. I will start eating at 7: 00 a.m. on the day of gastroscopy and take it every seven or eight minutes. I need to finish all the medicine in three hours until it is filled with clean water, and then it will be ready in the afternoon. I'm not allowed to eat it that morning or lunch. I just got back from Qilu Hospital two days ago. I hope my answer can help you.
