Besides，hand over hand cross and parallel techniques are needed to achieve the SILS. All the other operative procedures are the same as conventional laparoscopic surgery.
Conventional Laparoscopic Surgery
In this group，the surgery is performed through 3-5 ports according to the surgeons habits and specific conditions.
