Inguinal hernia is a common and frequent disease in general surgery. The traditional surgical treatment method uses the abdominal wall’s own muscle as the repair material, which has led to postoperative tension pain, slow recovery, many complications and high recurrence rate due to the defects in the design of this procedure. In 1989, Lichtenstein introduced the new concept of “tension-free” hernia repair. Tension-free hernia repair has been popularized because it conforms to the physiological anatomy. The postoperative results of the tension-free hernia repair group showed that it has the advantages of simple operation, mild postoperative pain, rapid recovery, low recurrence rate, and few complications compared with traditional surgery; the disadvantage is that some patients have a hard local sensation and sometimes have local tissue reaction, and in severe cases, the patch needs to be removed. In addition, there are still shortcomings from the minimally invasive point of view, because large incisions and separation of tissues are still needed to displace the spermatic cord. Third, laparoscopic minimally invasive inguinal hernia repair has now become the most widely used surgical procedure. Laparoscopic inguinal hernia repair is performed through two 5-mm and one 10-mm “keyholes” in the abdominal wall, where the laparoscope and hernia repair material (patch) are inserted to increase the strength of the abdominal wall for the purpose of healing the inguinal hernia. This procedure is a minimally invasive laparoscopic treatment and a type of tension-free repair, thus offering the advantages of both minimally invasive laparoscopy and tension-free hernia repair. Moreover, the surgical approach of this method is different from that of traditional hernia repair, especially in bilateral hernia, occult hernia and recurrent hernia. Compared with traditional hernia repair and tension-free hernia repair, laparoscopic hernia repair has the following advantages: 1. 3.Postoperative pain is light and analgesics are used sparingly; 4.Treatment of bilateral inguinal hernia does not require additional incisions, so it can achieve twice the effect with half the effort; 5.Concealed hernia can be found and repaired at the same time during surgery; complications are low, because laparoscopic surgery does not need to separate and destroy the perihilar tissue, so it does not cause scrotal edema and rarely causes urinary retention; 6.Treatment of recurrent hernia can avoid The original surgical incision can be avoided, making the operation simpler. 7. It fully conforms to the principle of tension-free repair. The disadvantages are: general anesthesia and high price. With the improvement of people’s living standard, minimally invasive has become a treatment trend accepted by people for sure.
