The cost of ESD is about 10,000 RMB. ESD is short for endoscopic submucosal resection, which is a minimally invasive procedure that is performed mainly under gastroscopy and colonoscopy to remove lesions in the stomach or colon, such as lesions within polyps or stage T1 tumors. The cost includes the cost of inpatient tests such as routine blood tests, biochemical tests, coagulation tests, hepatitis B tests and electrocardiograms, abdominal CT, gastroscopy or chest X-ray. The cost of surgery is also included. Of course, the cost of treatment after surgery is also included, because there is a possibility of bleeding from the trauma, which requires hemostatic drugs or prophylactic application of antibiotics, etc.
