The goal of this clinical trial is to learn if not giving antibiotics is as effective as giving antibiotics after surgery for patients who have surgery for a perforated (burst) appendix. This pilot study will also help determine whether a larger, multi-centre study can be successfully conducted. The main questions it aims to answer are:
* Do patients who do not receive antibiotics after surgery have similar rates of infection after surgery as patients who do?
* Is it feasible to enroll and randomize patients and collect complete health data for a larger multi-centre study?
Researchers will compare patients who do not receive antibiotics after surgery to patients who do to see whether avoiding antibiotics is as effective as using antibiotics for preventing infections after surgery.
Participants will:
* Be randomly assigned to either receive or not receive antibiotics after surgery for their perforated (burst) appendix.
* Be contacted 30 and 90 days after surgery to check for infections and other health outcomes.
