Disease characteristics: pediatric inguinal hernia, also known as “hernia”, “small bowel prolapse”, almost always caused by congenital hernias. Families often find a lump in the groin or scrotum when examining their baby, which is soft and elastic, and can be returned to the abdominal cavity by gently squeezing the lump upward with a finger. The mass can also appear when crying, coughing, straining to defecate, playing activities, and can disappear automatically when lying down quietly. The disease is more common in boys and less common in girls, and is the most common disease in pediatric surgery. Hiatal hernia can appear both on the right side and on the left side, bilateral lesions account for 10-20%, so sometimes it can be found, originally the right side of the hernia of the patient, soon after the completion of the surgical treatment, the left side of the emergence, of course, this situation is still more common. The danger of this disease: incarcerated hernia : inguinal or scrotal painful lumps, lumps of hard texture, the surface of the late congestion and redness. The baby appeared to cry and restlessness, nausea and vomiting gradually, if not treated in time, there can be a manifestation of intestinal obstruction, abdominal distension, the anus stops defecation. Disease duration within 12 hours, can first ask the physician manipulation reset, disease duration, the possibility of successful reset will be correspondingly reduced. Failure of repositioning or disease duration more than 12 hours, the baby’s general condition is poor need emergency surgery, and intussusception may lead to intestinal tubes, testicles, ovaries necrosis. Therefore, all babies with a history of intussusception should be operated on as soon as possible. Self-healing: This disease has a self-healing phenomenon, the overall chance is very low, almost always need surgery, in general, if the hernia block can not appear for 2-3 months, then continue to keep not appearing for a longer period of time, the more likely to be self-healing. Second, pre-operative preparation 1, no infectious diseases, such as: cold, pneumonia, diarrhea, etc.; no cough, chronic constipation. 2, before the operation, you need to wash the skin of the surgical area. The skin of the surgical area is not infected. Third, the risk of surgery: overall, the risk of surgical anesthesia is small. IV. Surgical method – high hernia sac ligation Optimal age for surgery: 6 months of age or older, preferably weighing 10 kg. incarcerated need immediate surgery. Elective surgery: â‘ Conventional surgery: make a transverse incision of about 1cm in length in the inguinal area and ligate the hernia sac in a high position. The incision is closed with cosmetic sutures and does not require suture removal. â‘¡ Minimally invasive laparoscopic surgery : It can detect hidden hernia on the other side, avoiding the situation that a patient with hernia on one side will have it again on the other side soon after completing the surgical treatment. Hospitalization time is 3-4 days. Rural cooperative medical care and urban residents’ insurance can report 50% of the cost in our hospital. V. Post-operative precautions 1. Disinfect the wound with complex iodine and change the band-aid every two days after discharge from the hospital. On the seventh day after surgery, remove the band-aid and take a bath. 2.Rest for 2 weeks (preferably in bed), and reduce the exercise within half a year, especially strenuous exercise, can be conducive to wound healing. 3, postoperative should pay attention to respiratory infections (such as colds, pneumonia, etc. due to cough); avoid lifting heavy objects (children); avoid violent crying and noise. 4, postoperative nutrition can be strengthened (improve malnutrition), enhance the physical fitness of children. Keep the bowel clear and prevent constipation. 5, 2 months after discharge from the hospital can come to the hospital for follow-up. Sixth, personal experience 1, the body is thin and easy to get sick and long-term constipation of children after surgery is easy to recurrence, this point needs to be avoided. 2.Frequently incarcerated children can be early surgery (less than half a year old)
