Advantages of laparoscopic inguinal hernia repair: 1, small wound: only 3 small holes in the abdominal wall with a total length of about 50 px. the advantage of bilateral hernia wound is more obvious. 2, light pain: the abdominal wall tissues do not need to be widely freed, which has the advantage of maintaining the strength of the abdominal wall, and the pain is mild, and you can resume normal life 1-2 weeks after surgery. 3.Less chance of patch infection: the placed patch is not in direct communication with the outside world, which reduces the infection rate of the wound and the patch. 4.Firm repair: The abdominal wall defect can be observed under direct vision, which can not only repair the formed hernia, but also prevent the occurrence of straight hernia, hiatal hernia and femoral hernia in the future. 5.Comprehensive observation: It can take advantage of lumpectomy to find one-time repair of hidden hernia that does not show clinical symptoms on the opposite side. 6.Better management of recurrent hernia: The structure of recurrent hernia hierarchy is destroyed and anatomy is unclear. For recurrent hernia after open surgery, lumpectomy is simpler and more reasonable to avoid the complexity.
