First, the anatomical characteristics of pediatric inguinal hernia 1, the inguinal canal is short. The distance between the inner and outer ring mouths is only 1cm, and there is no need to open the inguinal canal. The spermatic cord is raised, and the hernia sac is found to be simple to free to the extraperitoneal fat. 2, the hernia sac is the unclosed sheath, which is the main cause of the disease, so as long as the high ligation of the unclosed sheath to achieve the therapeutic purpose. In contrast, adult hernia etiology is due to weakness of the inguinal canal wall and abdominal pressure. The intact peritoneum bulges into the inside of the inguinal canal. 3, pediatric inguinal hernia characteristics and surgical treatment: due to its pathogenesis only need to be treated with high ligation, and the inguinal canal is short, so the surgery is simple. However, because in addition to avoiding surgical complications such as recurrence, infection, and pain, the protection of the reproductive system should come first, including the vas deferens, vas deferens vessels, testes, and spermatic cord vessels. Second, pediatric inguinal hernia treatment indications 1, surgical treatment: is the basic method of pediatric inguinal hernia treatment. Surgery after 6 months of age. Repeatedly incarcerated people are not limited by time. 2, non-surgical treatment: children with serious diseases that are not suitable for surgical treatment can be treated with a hernia belt. Injectable treatment is not suitable because of the many complications and serious. Many places still have propaganda hernia belt compression treatment, hernia belt compression treatment complications are traditionally thought to be easy to cause hernia out of the intestinal tube is compressed necrosis, in fact, the greater danger is the compression of the spermatic cord, we are familiar with the inguinal structure, hernia belt compression treatment of hiatal hernia is through the external compression of the inguinal canal, the spermatic cord, and the hernia sac inside the hernia sac, so that hernia sac adhesion to achieve the therapeutic purpose. The vas deferens, spermatic cord blood vessels can hardly be said to be able to avoid damage by compression, which can not be tolerated. And the compression time is long, strong, I have seen a case of compression for 2 years, the affected side of the lower limbs become thin. And it is relatively difficult to operate on a child who has had a hernia belt compression. In addition the age of surgery we recommend that the earlier the treatment after detection after 6 months the better, the reason is to prevent the appearance of incarceration. We also take into account another reason, which is the temperature of the scrotum on the affected side, the temperature inside the scrotum should be similar to the abdominal cavity, which will affect the development of the testicles. Third, the operation methods and procedures of pediatric inguinal hernia 1, transinguinal hernia sac high ligation. 2.Transabdominal hernia sac high ligation. 3, Laparoscopic hernia sac high ligation. The aim of all three methods is to high ligate the hernia sac. Repair and strengthening of the inguinal canal wall is rarely necessary.
