1. Preoperative examination

patients need to fast for a certain period of time, usually 8 to 12 hours, to ensure that the stomach is empty, which is conducive to the examination operation and observation results. In addition, patients need to undergo routine examinations, such as blood routine, urine routine, etc., to eliminate contraindications.

2. Intraoperative operation After

At the same time, tissue samples can be taken by gastroscope for pathological examination.
