Both traditional and minimally invasive surgery are done with local anesthesia, and the pain is similar if the anesthesia is effective, and both are not very painful. The difference between them is: 1. Traditional surgery has a large surface wound, which is designed according to the size and mobility of the mass, while minimally invasive surgery has a small surface wound, about 0.5cm; 2. Traditional surgery is an extraperitoneal excision of the mass, which will not destroy the structure of the mass itself and the excision is relatively complete; minimally invasive surgery uses a needle with a groove of about 2*0.5cm for rotary cutting, and the mass will be cut into a strip of If the mass is larger, it may remain. 3, the cost of traditional surgery is at most 900 yuan, outpatient surgery can not be reimbursed; minimally invasive surgery requires about 6000, of which 5000 is the cost of needles and hemostatic materials, can not be reimbursed. 4, post-operative recovery problems, traditional surgery stitches to stop bleeding and pressure bandage, relatively few cases of hematoma; minimally invasive surgery can not be stitched, can only fill absorbable hemostatic gauze and pressure bandage; post-operative must be half a month can not be strenuous activities.
