ESD surgery is also known as endoscopic mucosal stripping, and normally, gastric endoscopic mucosal stripping returns to normal within 1 week. Gastric endoscopic mucosal stripping is mostly used in the treatment of early gastric cancer and gastric polyps, etc. It is mainly performed by stripping the gastrointestinal mucosa in the lesion area so as to maximize the preservation of gastric integrity and to achieve the purpose of early treatment. Gastric endoscopic mucosal stripping surgery is less invasive, and after the surgery, it is necessary to place a gastric tube to drain the stomach, and by observing whether there are any traumatic bleeding, perforation and other serious complications, and giving the injection of omeprazole sodium to inhibit acid therapy, and giving the injection of hemocoagulase to prevent bleeding, usually it can be returned to normal within 1 week after the surgery, and can be put on a semi-fluid diet. After gastric endoscopic mucosal stripping, gastroscopy should be reviewed regularly to prevent further progression of the disease, and if gastrointestinal discomfort occurs, go to the hospital in time.
