A new type of hernia treatment surgery is performed completely outside the peritoneum, without contacting the abdominal organs, without creating abdominal adhesions, with small incisions and less susceptible to infection, which is the future trend of hernia surgery. Since the artificial mesh repair is performed at the weakest point, the artificial mesh can be fused with the abdominal wall tissues without sutures to form a highly tension-resistant union. The recurrence rate is low, generally around 1%, and doctors with rich experience in laparoscopic surgery can further reduce the recurrence rate to 0.1%. 2. Fast recovery, not easy to be infected: because of the small wound, the postoperative pain is light, the discomfort reaction is small, the recovery is fast, the chance of wound infection is low, and the surgeon can go home for daily life on the second day after the operation, and can resume work one to two weeks after the operation. Scope of application It is most suitable for bilateral inguinal hernia and recurrent hernia; the operation is technically difficult and requires a surgeon with rich experience in laparoscopic surgery to perform.
