Hernia is a common disease, commonly known as “small intestine hernia”, whose main cause is a weakness or defect in the transverse abdominal fascia. When the pressure in the abdominal cavity increases, the organs in the abdominal cavity protrude outward from the weakness or defect to form a hernia. The main hazard of hernias is that they can easily lead to embedded necrosis of the small intestine, which is especially dangerous when working in the field or traveling long distances. Therefore, repairing the weak or defective abdominal wall becomes a fundamental part of the treatment. Hernia can be classified according to the site of occurrence: inguinal hernia, umbilical hernia, and white line hernia. There are also incisional hernias and parastomal hernias that form as a result of surgery. Traditional inguinal hernia repair, in which the defect is repaired with its own tendon tissue. The main disadvantages are large incision, postoperative pain, high tension, high incidence of long-term postoperative pain, weak tendon tissue (such as the elderly), and the biggest disadvantage of this operation is the suspicion of “tearing down the east wall to repair the west wall”, so the recurrence rate after surgery is high; in recent years, tension-free hernia repair for hernias has been gradually developed at home and abroad, which uses This method uses polymer material to repair the abdominal wall defect from the place. The problem of long-term postoperative pain has been solved, but a small number of patients may experience a significant foreign body sensation, and a very small number of patients may experience rejection of the patch or infection, which may lead to long-term wound non-healing and even require a second operation to remove the patch. As a new type of surgery, what is the advantage of laparoscopic inguinal hernia repair? It is the most suitable surgical approach for inguinal hernia anatomy, as it replaces the previous two approaches of “plugging” the defect from outside and “patching” the defect from inside the abdominal cavity in front of the transverse abdominal fascia. Compared with the first two surgical methods, it has 1. aesthetic wound and less damage; 2. fast postoperative recovery and short hospital stay; 3. mild postoperative pain; 4. unilateral and bilateral inguinal hernias (straight, oblique and femoral) can be treated in one method without additional incisions; 5. low complications, no scrotal edema and very little urinary retention; 6. no destruction of the natural structure of the inguinal region; 7. 7. It conforms to the principle of tension-free repair and no long-term postoperative pain. 8 .Low recurrence rate after surgery. It is especially suitable for the treatment of recurrent hernia and incisional hernia, and is the best treatment for all kinds of hernia in the future. Of course, compared with traditional surgery, the cost of laparoscopic hernia repair is slightly higher.
