ESD surgery for intestinal flat polyps is not risky, ESD surgery, also known as endoscopic submucosal dissection, enables endoscopic dissection of intestinal flat polyps and has certain advantages and disadvantages. 1.Advantages. Minimally invasive surgery, less traumatic surgery, less intraoperative bleeding than open surgery, can avoid the risk of infection and bleeding that may arise from open surgery, better prognosis and faster recovery. 2. Disadvantages: ESD surgery can only strip the mucosa of the lesion, and cannot radically resect the lesion in a larger and deeper part of the lesion, so there is a possibility of recurrence, and there is a possibility of perforation complicating ESD surgery. It is recommended that patients stay in bed for 24 hours after ESD surgery and communicate with the attending physician if they have any physical discomfort. In addition, the cost of ESD surgery is relatively high, so it is recommended to choose according to their own conditions.
