Minimally invasive surgery encompasses many aspects, mainly including minimally invasive laparoscopic surgery, minimally invasive endoscopic surgery, minimally invasive interventional ultrasound surgery, and minimally invasive interventional radiologic surgery. For example, if a patient wants to have an appendectomy, the appendix used to be removed by open surgery, but now the appendix can be removed laparoscopically, with only 2-3 incisions or even only one incision in the abdomen. If a patient wants to have a radical resection of colon cancer, which used to require a long incision of about 20cm, the surgery can now be done down using only 4-5 small incisions. In the past, if there was intestinal bleeding, only conservative treatment could be given or part of the intestinal tube could be removed, which was more traumatic. Currently, interventional embolization of the bleeding vessel can be performed under X-ray, which can solve the fundamental problem and is very traumatic at the same time.
