? Laparoscopic inguinal hernia repair is a minimally invasive surgery developed in recent years on the basis of tension-free hernia repair, and its biggest advantage is that it can laparoscopically examine both inguinal triangles at the same time and repair them at the same time. For recurrent hernia, laparoscopic hernia repair can avoid damage to the nerves and spermatic cord and vas deferens through the original incision, especially for bilateral hernia, recurrent hernia, and concomitant diseases that can be dealt with laparoscopically at the same time. Currently, there are the following common types of microscopic surgery: ① Transabdominal Preperitoneal Patch Implantation (TAPP); ② Totally Extraperitoneal Patch Implantation (TEP). Since Lichtenstein first proposed the concept of tension-free hernia repair in 1986, the classic anterior tension repair has gradually withdrawn from the stage of history, and open tension-free hernia repair has become the gold standard for inguinal hernia in modern clinical surgery, while laparoscopic inguinal hernia repair is a new type of inguinal hernia treatment surgery, which is performed completely outside the peritoneum without contacting the intra-abdominal organs and without producing abdominal mucosa. It is a new type of inguinal hernia treatment surgery, which is performed completely outside the peritoneum, without contacting the intra-abdominal organs, without producing abdominal adhesions, with small incisions and less susceptible to infection, and it is the development trend of hernia surgery in the future. Modern surgical anatomy has confirmed: the breakage or loosening of the transversal abdominal fascia is the most fundamental cause of inguinal hernia (hernia or small intestinal gas), to restore the anatomical integrity of the transversal abdominal fascia is the basic principle that any kind of hernia repair should follow. Operations that violate this principle are an important factor in hernia recurrence after inguinal hernia repair. Laparoscopic hernia repair is designed to follow this principle, utilizing a large patch to cover the entire abdominal wall defect area, including hiatal hernia, rectal hernia, femoral hernia, etc., effectively restoring the integrity of the transversal abdominal fascia, and providing a more thorough repair with a lower recurrence rate. With the traditional open tension-free hernia repair, it can completely avoid the postoperative chronic pain, patch foreign body sensation, wound infection, scrotal redness and swelling, scrotal effusion and blood accumulation, orchitis, testicular pain, testicular atrophy, discomfort in sex life, varicose veins of the spermatic cord, adhesion between the patch and the spermatic cord caused by vasovaginal obstruction of azoospermia and other serious complications of the traditional surgery. The procedure is technically difficult and needs to be performed by a surgeon with extensive experience in laparoscopic surgery. The development of this technology has greatly improved the level of minimally invasive surgery in our hospital, and our minimally invasive surgery department has routinely carried out two types of laparoscopic hernia surgeries, TAPP and TEP, which have produced good social and economic benefits. At present, the direction of surgical development has gradually shifted from traditional surgery to minimally invasive development, and most of the general surgical procedures can be performed by minimally invasive surgery. Laparoscopic hernia repair surgery through laparoscopic equipment and instruments for the treatment of extra-abdominal hernia disease has been widely carried out abroad, and the number of cases in China is also increasing year by year. Compared with traditional surgery, laparoscopic hernia repair surgery has great technical advantages, high technical content, in line with today’s trend of minimally invasive development of surgery, and has high academic value. The maturity of this technology in our hospital, breaking the traditional concept of targeted repair of hernia repair, a mesh patch to completely repair the inguinal hernia, straight hernia, femoral hernia of the weak area, it can be said that a “net” hit all! Moreover, there is no long scar on the abdominal wall after surgery, which is more in line with the principle of medical aesthetics. It is a practical technology worth learning and popularizing.
