Context: Nonoperative treatment (NOT) with antibiotics alone of acute uncomplicated appendicitis (AUA) in children has been proposed as an alternative to appendectomy.
Objective: To determine safety and efficacy of NOT based on current literature.
Data sources: Three electronic databases.
Study selection: All articles reporting NOT for AUA in children.
Data extraction: Two reviewers independently verified study inclusion and extracted data.
Results: Ten articles reporting 413 children receiving NOT were included. Six, including 1 randomized controlled trial, compared NOT with appendectomy. The remaining 4 reported outcomes of children receiving NOT without a comparison group. NOT was effective as the initial treatment in 97% of children (95% confidence interval [CI] 96% to 99%). Initial length of hospital stay was shorter in children treated with appendectomy compared with NOT (mean difference 0.5 days [95% CI 0.2 to 0.8]; P = .002). At final reported follow-up (range 8 weeks to 4 years), NOT remained effective (no appendectomy performed) in 82% of children (95% CI 77% to 87%). Recurrent appendicitis occurred in 14% (95% CI 7% to 21%). Complications and total length of hospital stay during follow-up were similar for NOT and appendectomy. No serious adverse events related to NOT were reported.
Limitations: The lack of prospective randomized studies limits definitive conclusions to influence clinical practice.
Conclusions: Current data suggest that NOT is safe. It appears effective as initial treatment in 97% of children with AUA, and the rate of recurrent appendicitis is 14%. Longer-term clinical outcomes and cost-effectiveness of NOT compared with appendicectomy require further evaluation, preferably in large randomized trials, to reliably inform decision-making.
