The diagnosis of pediatric appendicitis is confirmed with a typical history, physical examination, and ancillary tests. Patients will have significant right lower abdominal pain or metastatic right lower abdominal pain, especially in pediatric patients, and gastrointestinal symptoms such as nausea and vomiting are very evident. Due to the underdevelopment of the greater omentum in pediatric patients, the appendix, if infected, can easily spread and lead to the development of diffuse peritonitis. There will be significant pressure points on examination with rebound pain and muscle tension, increased skin temperature, diminished bowel sounds on auscultation and a drum sound on percussion, and severe effusion will also show a positive mobile turbid sound. The blood picture of pediatric appendicitis can be abnormally high, and early diagnosis should lead to prompt surgical treatment. In some patients, B-mode ultrasonography may reveal significant swelling of the appendix and even changes in the density of fluid exuding from the appendix.
