Acute appendicitis is the most common acute abdominal condition in pediatric patients and can occur at any age, but most commonly in the age group of 5 to 12 years. Since the appendix wall is thinner in children than in adults, it is easy to perforate and develop diffuse peritonitis, which can bring serious complications and even death if not diagnosed and treated in time, so early diagnosis is crucial. Infants and young children, because of their inability to express themselves, only show symptoms such as paroxysmal crying, refusal to press on the abdomen, and reluctance to move along with vomiting and diarrhea. In older children, the pain starts around the belly button and gradually becomes fixed in the right lower abdomen. Since appendicitis is mostly associated with obstruction of the appendiceal cavity, this abdominal pain is often paroxysmal and becomes more and more intense. Appendicitis in older children has the same abdominal pain as in adults especially the typical right lower abdominal pain, vomiting, diarrhea, fever, temperature up to 39-40°C, and even severe systemic symptoms such as seizures, high fever, and convulsions. The occurrence of pediatric appendicitis is often associated with cold, upper respiratory tract infection, tonsillitis, diarrhea, gastrointestinal dysfunction, and inappropriate deworming. Parents should pay special attention to the above-mentioned triggers, any child with abdominal pain, especially pain lasting more than 6 hours without relief or even gradually aggravated, accompanied by vomiting, fever and other symptoms, should be highly alert to the possibility of appendicitis, and should promptly go to a hospital in a position to diagnose, preferably to a pediatric surgeon. Since pediatric appendicitis is very prone to perforation, which often develops into diffuse peritonitis, surgery is preferred once pediatric appendicitis is diagnosed. Conservative treatment must be done carefully, only in children with serious illnesses that contraindicate surgery and in children with a history of more than 5 days of appendiceal abscess formation, treatment should be performed under the close supervision of a specialist. There are two options for surgery: traditional open surgery and laparoscopic surgery. Laparoscopic appendectomy is preferred because of the advantages of small hand injury, fast recovery and small or even no postoperative abdominal scarring.
