1.Safety: Since laparoscopic surgery is both gently operated and shortens the operation time. Therefore there is no wound pain. In addition, the use of high-brightness illumination and camera technology magnifies the tissue, making the scope of the surgical field of view increase, greatly avoiding the omission of lesions and tissue damage. 2.Little trauma and fast recovery of patients after surgery: The operator’s hand operates outside the body and does not enter the body, and what enters the body is only tiny and fine surgical instruments, avoiding the pulling of the instruments of open surgery, reducing the damage to the plasma membrane layer of the abdominal organs and avoiding the adhesions of the abdominal organs after surgery. Patients can move freely 1 day after surgery, and there is no obstacle to urination and venting. 3.Less bleeding: Since laparoscopic surgery is a refined operation, it makes various tissues easier to identify, which can shorten the operation time and reduce bleeding. 4, short hospitalization: laparoscopic surgery does not require a long hospital stay, generally 3 days after surgery can be discharged, a week after resuming normal life, work. 5, abdominal wall cosmetic effect: laparoscopic surgery only in the umbilical port and lower abdomen to do 5-10mm puncture, small incision, beautiful, especially suitable for female beauty needs. 6, less pelvic adhesions: laparoscopic surgery on the pelvic cavity interference is small, no gauze or sutures and other contact with the tissue, so that the postoperative pelvic and abdominal adhesions are far less than the transabdominal surgery. 7, save medical costs: laparoscopic surgery after the reduction of hospital days, rapid postoperative recovery, the reduction of medication, all make the patient cost reduction. 8, both diagnostic and therapeutic role: laparoscopy can replace most of the transabdominal dissection, so that patients and physicians to avoid blind open abdominal surgery, on the other hand, laparoscopic technology diagnosis at the same time can carry out surgical treatment, especially in acute appendicitis, intestinal adhesions and other diseases, its superiority is more obvious.
