Description of intervention(s) / exposure
Treatment: Drugs - Non-operative management group (NOM)
Experimental: Non-operative management group (NOM) - Children in the NOM group will receive intravenous Piperacillin with Tazobactam (Tazocin) 100mg/kg/dose every 8 hours for at least 24 hours, and they will be observed and reassessed within 24 hours after randomisation. A further 24 hours of intravenous Piperacillin with Tazobactam therapy will be offered to children in invariable condition. A clinical decision will be made by the attending surgeon to offer OM if a patient's condition deteriorates at any time, or if a patient has failed to improve after 48 hours of intravenous antibiotic therapy. Once the patient is clinically improving and tolerating oral intake, the antibiotic regimen will be changed to oral Amoxicillin plus Clavulanic acid (Augmentin) 22.5mg/kg/dose twice per day to complete a total seven day course of antibiotics. Oral Ciprofloxacin 15mg/kg/dose twice daily and oral Metronidazole 10mg/kg/dose twice daily will be offered to children who are known to have an intolerance or allergy to Amoxicillin or Clavulanic acid.
Active comparator: Appendectomy group (Operative management, OM) - Children allocated to OM may receive preoperative antibiotic prophylaxis as clinically indicated. Appendicectomy will be performed laparoscopically, or via open surgery according to the surgeon's standard practice. Postoperative antibiotic treatment will be determined on the basis of intraoperative findings in accordance with the institutional practice. The appendix specimen will be examined by a paediatric pathologist, and the formal histopathology report will be recorded.

Summary
Brief summary
This study is designed to determine the safety and efficacy of non-operative antibiotic management of clinically diagnosed acute uncomplicated appendicitis in children. Enrolled patients will be randomised and an allocation ratio of 1:1 will be made via weighted minimisation, where half of the patients will receive non-operative management with intravenous Piperacillin with Tazobactam, while the other half will have an appendicectomy.
