Minimally invasive surgery in clinic mainly refers to laparoscopic surgery, which is widely used in clinic due to its small trauma, light pain and fast recovery. However, laparoscopic surgery also has its shortcomings: 1. As laparoscopic surgery requires the establishment of carbon dioxide pneumoperitoneum, prolonged carbon dioxide pneumoperitoneum may cause hypercapnia, which may cause or appear delayed awakening of the patient, or even secondary respiratory diseases. 2. It is better not to use laparoscopic exploration for trauma patients, because the use of laparoscopic exploration of trauma is prone to omission and serious complications, and in severe cases, even endanger the life of the patient. 3. At present, some researches think that for early stage cancer, if laparoscopic treatment is used, it will even affect its long-term survival rate.
