Perforated Appendicitis and Postoperative Antibiotics Pilot Trial

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.

Use of Antibiotic Irrigation to Decrease Wound Infections in Pediatric Perforated Appendicitis

The proposed study will investigate whether antibiotic irrigation using a gentamicin/clindamycin solution during laparoscopic appendectomy is superior in preventing postoperative wound infections and IAA in perforated appendicitis compared to suction without irrigation. This will be the first prospective study to compare these two options in pediatric PA.

APPI-Cost Trial for Perforated Appendicitis

The purpose of this study to assess the clinical effectiveness and cost-effectiveness of povidone-iodine (PVI) irrigation in perforated appendicitis, to investigate barriers and facilitators to future implementation of PVI irrigation, and to collect costs and clinical and patient-reported outcomes among patients with non-perforated appendicitis.

Effect of Intraperitoneal Drain Placement on Postoperative Outcomes Following Laparoscopic Appendectomy in Adult Patients With Perforated Appendicitis

Acute appendicitis is the most common acute abdomen, and a small number of patients can progress to perforated appendicitis, which has significantly higher complications than non-perforated appendicitis. Appendectomy is the only option for treating perforated appendicitis. Optimizing the diagnosis and treatment of perforated appendicitis is of great significance to improve its clinical outcomes and save medical resources. There is a consensus that drainage should not be placed after surgery for non-perforated appendicitis, but the decision to place drainage for perforated appendicitis remains controversial. Several retrospective studies have shown no benefit in postoperative recovery and hospital stay, and may lead to increased infectious complications and longer hospital stays. A small number of prospective studies have shown similar conclusions, but the sample size is too small, most of them are children, and there is a lack of large-scale multicenter studies. The investigators' preliminary retrospective survey suggests that in China, most surgeons still commonly place drains for peace of mind after surgery with perforated appendicitis in adults without seeing a clear benefit, so there is a need for a multicenter prospective randomized controlled study to evaluate the need for drainage placement after perforated appendicitis and to guide clinical practice with evidence. To study the effect of abdominal drainage on the postoperative clinical outcomes of adult patients with perforated appendicitis, mainly including: infectious complications (residual infection or abscess in the abdominal cavity, incision infection, fecal fistula, etc.), case fatality rate, pain score, length of hospital stay (LOS), quality of life (QOL) score, etc.
