Minimally invasive surgery can be performed for bowel cancer. At present, many hospitals and departments basically adopt minimally invasive surgery for bowel cancer surgery, that is, radical surgery for bowel cancer under laparoscopy. This includes laparoscopic radical treatment of right hemicolectomy, laparoscopic radical treatment of left hemicolectomy, laparoscopic radical treatment of rectal cancer, etc. The decision is mainly based on the location of the tumor, because laparoscopic radical treatment of intestinal cancer has obvious advantages, compared with traditional open surgery, laparoscopy has the function of magnification, so the local anatomy is very good during the surgery, and it can clearly distinguish the blood vessels, tracts, and even It is possible to clearly distinguish the vessels, tracts and even the nerves. The operation is very delicate and basically does not bleed during the operation, and the nerves can be preserved after the operation, so that many functions of the patient can be preserved, and after the patient’s operation, the abdominal pain is significantly reduced and the gastrointestinal function recovers more quickly.
