After EMR surgery, the following points should be noted: 1. It is recommended to fast for 1 day and to have a liquid diet for 1-3 days, and gradually transition to a normal diet; 2. Because the wall of the digestive tract will become thin after mucosal resection, an artificial ulcer will be formed. It takes at least 1 month for the ulcer in the upper digestive tract to heal, and it may take longer for the lower digestive tract, 1.5-2 months for the wound to heal. Therefore, the postoperative diet should be well digested soft food or liquid or semi-liquid food; patients should not be strenuously active, in order to prevent bleeding and inhibit perforation, the trauma is closed with titanium clips, if strenuous movement of titanium clips may cause medical damage to the wall of the digestive tract and even perforation. EMR or ESD are currently the better minimally invasive surgical methods for endoscopic solution of digestive tract tumors, early cancer, benign tumors, etc., which have benefited many patients. It has benefited many patients, and many patients who originally needed surgical operation can now be solved by minimally invasive endoscopic surgical methods. With the improvement of people’s awareness, more and more patients are undergoing gastrointestinal examination and more and more early lesions are found. The incidence of gastrointestinal tumors is very high, reaching 40%-50% of all tumors, so it is recommended that people should raise their health awareness and have regular medical checkups. Without gastroscopy, lesions cannot be detected. Only by performing gastroscopy, discovering early lesions and treating them in time, can we avoid tumor progression and improve people’s health.
