Piperacillin/Tazobactam Versus Ceftriaxone and Metronidazole for Children With Perforated Appendicitis

The ALPACA-MC trial is a blinded, multicentre randomized controlled trial comparing two postoperative antibiotic treatments for children undergoing laparoscopic appendectomy for perforated appendicitis. Perforated appendicitis occurs when the appendix has developed a hole or has burst. The study will include 180 children from several pediatric hospitals. After surgery, participants will be randomly assigned to receive either piperacillin/tazobactam (PT) or ceftriaxone plus metronidazole (CM). The child, family, healthcare team, and researchers assessing the outcomes will not know which treatment was received. The main purpose of the study is to determine whether PT reduces hospital length of stay compared with CM. The study will also compare other important outcomes, including surgical site infections, the need for additional imaging or procedures, emergency department visits, and hospital readmissions. Children will be followed for 30 days after surgery. At 30 days, families will be contacted to ask about any additional complications and how well the child has recovered. This will include questions about returning to school, sports or other physical activities, and the child's overall health and quality of life. The results of this study will help determine which antibiotic treatment is most appropriate for children with perforated appendicitis and may help guide future clinical practice and antibiotic stewardship.

Piperacillin/Tazobactam Versus ceftriAxone and Metronidazole for Children With Perforated Appendicitis (ALPACA)

This study is an internal pilot for a multicenter, blinded randomized controlled trial. The purpose of the multicenter trial is to determine whether post-operative piperacillin/tazobactam is more effective than ceftriaxone and metronidazole for children treated with laparoscopic appendectomy for perforated appendicitis. We plan to conduct an internal pilot study to determine whether a blinded multicenter randomized controlled trial is feasible.

Enhanced Recovery After Surgery (ERAS) for Complicated Appendicitis

The exploratory objective of this pilot study is to evaluate the feasibility and safety of an enhanced recovery protocol that will allow adult patients to be discharged to home on an oral antibiotic regimen for three days following a laparoscopic appendectomy for complicated appendicitis. Feasibility will be determined by high compliance and adherence of patients to the postoperative instructions, while safety will be assessed by the incidence of postoperative infectious complications and requirement for re-admission.
