The principle of treatment for appendicitis in a ten-year-old child is early surgery with fluids and other treatments. Ten-year-old children due to the large omentum is not yet fully developed, and can not play a sufficient protective role; and at this time the child’s expression and cognitive ability is not yet fully mature, the provision of medical history is likely to be biased, so children’s appendicitis is characterized by rapid and severe development of the disease, signs are not obvious and atypical, the rate of perforation is high, and there are many complications. Therefore the principle of treatment is mainly early surgery. For appendicitis in 10-year-old children, it is now generally accepted that early surgery should be performed to avoid delay and serious consequences. Surgical methods include open and laparoscopic appendectomy, the choice of which should be based on the specific condition of the child. Surgery should be accompanied by fluids to correct dehydration and fight infection. If a child develops appendicitis-related symptoms, it is recommended to consult a doctor promptly to avoid delaying the disease.
