Laparoscopic surgery has the following advantages compared with traditional surgery: 1. Laparoscopic surgery disturbs little of the organs in the abdominal cavity and avoids the irritation and pollution of the abdominal cavity by air and dust bacteria in the air. Intraoperative ultrasonic knife, bipolar electrocoagulation operation is the main operation, the blood vessels are first coagulated and then broken, hemostasis is complete, bleeding is minimal, rinsing is thorough before the end of the operation to keep the abdominal cavity clean. Thus, the postoperative intestinal function recovers quickly, can eat earlier, and greatly reduces the factors of postoperative intestinal adhesions. 2, laparoscopic surgery is a representative of real minimally invasive surgery, trauma is greatly reduced, the surgical process and postoperative recovery is easy and less painful. 3, after surgery can be early out of bed, sleep position is relatively free, greatly reducing the intensity of family members accompanying care. 4.The abdominal wall poke holes are small (ranging from 3-10mm), scattered and concealed, and do not affect the aesthetics after healing. 5.General anesthesia is generally used, the monitoring is complete, and the safety is greatly increased. 6, poke hole infection is far less than the traditional open incision infection or fat liquefaction. 7, abdominal wall poke hole instead of abdominal wall incision, avoid the injury of abdominal wall muscles, blood vessels and the corresponding nerves, postoperative weakness of the abdominal wall and abdominal wall incision hernia will not occur, will not affect the motor function because of abdominal wall muscle scarring, will not cause the corresponding skin numbness because of abdominal wall nerve cut.
