Can Antibiotic Therapy Replace Surgery in Pediatric Acute Uncomplicated Appendicitis? An Updated Meta-Analysis of...

The efficacy of nonoperative management (NOM) for pediatric uncomplicated appendicitis (UA) remains controversial, with a paucity of large-sample randomized controlled trials (RCTs). This study aims to evaluate the efficacy of NOM for pediatric UA through a meta-analysis of updated RCTs.

We systematically searched the Web of Science, Embase, Cochrane Library, and PubMed databases from their inception to April 18, 2025. RCTs comparing NOM with operative management (OM) for pediatric UA were included. Meta-analysis was performed using RevMan 5.3 software. Primary outcomes included initial treatment failure, 1-year post-discharge treatment failure, and overall treatment failure. Quality of life and treatment costs were analyzed qualitatively.

Five RCTs involving 1423 patients were included (NOM: 738; OM: 685). Meta-analysis demonstrated significantly higher rates of initial treatment failure (OR: 3.14, 95 % CI: 2.10-4.71; P < 0.00001; I² = 0 %), 1-year post-discharge treatment failure (OR: 20.53, 95 % CI: 5.37-78.48; P < 0.0001; I² = 19 %), and overall treatment failure (OR: 8.47, 95 % CI: 5.82-12.35; P < 0.00001; I² = 0 %) in the NOM group compared with the OM group. NOM was associated with higher adverse event incidence rates, prolonged hospitalization duration, and increased rehospitalization frequency, but reduced school absence days. No significant difference was observed in days to normal activity between the two groups.

Current evidence from updated large-scale RCTs confirms the inferior efficacy of NOM compared to OM for pediatric UA. OM remains the primary treatment strategy, while NOM may be considered for select cases with careful risk-benefit evaluation.
