What's the difference between surgery and minimally invasive surgery?

Condition analysis: Minimally invasive surgery is mainly carried out by using advanced equipment such as laparoscopy and hysteroscopy, and the incision is reduced to a few millimeters at a time, which greatly reduces the trauma and scar caused by the operation. Suggestion: Compared with traditional open surgery, minimally invasive surgery has the following incomparable advantages: 1. The patient's pain is small: due to intravenous anesthesia, the patient can complete the surgical treatment in his sleep; 3. Fast postoperative recovery: short hospitalization time after minimally invasive surgery, and discharge in 2-4 days; 4. Reduction of surgical expenses: the probability of surgical infection is small, the hospitalization time is short, and the surgical expenses are relatively reduced.
