Pediatric inguinal hernia is a congenital anomaly that is familial, but there is no medical evidence of heredity. Hernia is mostly painless when there are no complications, but at any time big trouble can happen – an ingrown hernia, that is, the intestines in the stomach or the fallopian tubes of the girl’s ovaries enter the hernia sac and are tightly strangled and stuck back! The child will be in severe pain, crying, vomiting, not even eating or pooping, and the intestines or ovaries will be necrotic. Therefore, hernia is a minor disease on the surface, but it is still a tragedy that children lose their lives due to negligence and delay in medical treatment. The best way to treat pediatric inguinal hernia is surgery. There is no age limit for surgery and it is best to operate early if there is a hernia to avoid incarcerated hernia. In terms of the choice of surgical modality, laparoscopic minimally invasive is especially preferred, with small incisions and the possibility of detecting contralateral occult hernias and avoiding reoperation. Myths about the treatment of pediatric inguinal hernia: ① Hernia belt therapy, which is called card, is generally not used. The use of hernia belt makes local muscle atrophy and adhesion by long-term compression, which makes surgery difficult. ② Injection therapy, which is absolutely undesirable. Blind injection of sclerosing agent can cause serious consequences such as testicular atrophy, cryptorchidism, intestinal adhesions and intestinal necrosis.
