Compared with traditional surgery, its main advantages are: 1. small incision: the laparoscopic incision is only 0.3-0.4 cm, no suture is needed, the scar is very small and it is a cosmetic incision. 2. 2, good efficacy: for patients with dominant hernia on one side and recessive hernia on the other side, laparoscopic surgery can detect the contralateral recessive hernia and solve the problem at the same time, avoiding re-operation. 3.Low injury: This procedure does not require dissection of the inguinal canal and separation of the spermatic cord, so it will not damage the levator muscle, spermatic cord, blood vessels and nerves. 4.Low recurrence: According to the statistics, the recurrence rate of traditional surgery is 2% to 4%, while the recurrence rate of laparoscopic surgery is less than 1%. 5.Short operation time: laparoscopic surgery is easy and quick, and the operation time is short, only 10-15 minutes, and you can eat and get out of bed after 6 hours.
