Effect of peritoneal drainage on the prognosis following appendectomy in pediatric patients with appendicitis: a retrospective study based on appendicitis grade

Topic overview

Key takeaways

• Appendicitis grade predicts postoperative intra-abdominal abscess risk and length of hospitalization in pediatric patients.
• Grade I appendicitis: avoid peritoneal drainage—no drainage yields faster recovery and fewer complications than passive or active drainage.
• Grade ≥II appendicitis: active drainage reduces antibiotic duration and hospital stay compared to passive drainage.
• No drainage group had significantly lower wound infection and overall complication rates across all appendicitis grades.
• Active drainage allows earlier drain removal than passive drainage but may increase hospital stay in some higher-grade cases.
