Hernia causes great disturbance to the child’s normal development and life, and when it is serious, it has to be treated by open surgery, which is harmful to the child’s body. In order to prevent children from suffering from the disease, parents should do a good job in preventing pediatric hernia: 1. Parents should always pay attention to the child’s body to see if there is a swollen sac or a block that appears from time to time in the groin or scrotum of the child, and consult the doctor when in doubt. Methods: 55 cases of single-hole double-cannula three-instrument laparoscopic cholecystectomy were performed by taking an incision at the right edge of the umbilicus, placing a Trocar, establishing an artificial pneumoperitoneum, placing a 5mm Trocar at the upper edge of the umbilical observation hole about 3mm, and establishing an orifice at the lower edge of the umbilical observation hole 3mm and then directly placing a 3mm non-invasive grasping forceps, and completing cholecystectomy with ordinary laparoscopic instruments and ultrasonic knife. 2, Some parents worry about their children’s abdomen getting cold leading to illness, and often wrap their children’s abdomen up, but they should be careful not to wrap their children’s abdomen too tightly to avoid aggravating intra-abdominal pressure. Do not let the child learn to stand prematurely or stand for a long time to avoid the intestinal tube falling down to form an inguinal hernia. 3. Pay attention to arranging the child’s diet and let the child eat more easily digestible and fiber-rich foods to keep the stool open. When the child has dry stools, take laxative measures and do not let the child use force to relieve the stool. 4. Pay attention to weather changes and temperature differences between morning and evening, and increase and decrease your child’s clothing as needed to avoid your child catching a cold. If your child has a cold and cough, take some cough medicine under the guidance of a doctor and avoid crying loudly to prevent the abdominal pressure from rising due to violent coughing or crying, which may cause a hernia. 5. If your child has had a hernia but has been cured, after treatment, you must do a good job of protection to prevent recurrence, pay attention to exercise and diet, and do a good job of protection according to the doctor’s orders.
