Laparoscopic inguinal hernia repair is performed through two 5-mm and one 10-mm “keyholes” in the abdominal wall, where a laparoscope and hernia repair material (patch) are inserted to increase the strength of the abdominal wall and heal 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. The specific advantages are as follows: 1. light postoperative pain; 2. fast postoperative recovery: patients can be discharged in 2-3 days after laparoscopic surgery; 3. cosmetic effect: traditional open surgery requires an incision of about 7-8 CM in the inguinal region, while laparoscopic surgery requires only three small incisions of 0.5-1.0 CM in the abdominal wall, with remarkable cosmetic effect; 4. treatment of bilateral inguinal hernia does not require additional incisions. Therefore, the effect can be achieved with half the effort; 5. hidden hernia can be found and repaired at the same time; 6. treatment of recurrent hernia can avoid the original surgical incision and make the operation simpler.
