How many adults with acute appendicitis needed surgery within 10 years after taking antibiotics?
For adults with uncomplicated acute appendicitis, antibiotics are a safe alternative to surgery in the short term. However, the risk of recurrence over a decade is significant. A 10-year follow-up of a major clinical trial found that nearly half of patients initially treated with antibiotics eventually needed an appendectomy.
What the research says
The best long-term data comes from the APPAC trial, which followed 257 adults with CT-confirmed uncomplicated appendicitis who received antibiotics. At 10 years, 44.3% of patients had undergone appendectomy, and 37.8% had a recurrence of appendicitis 5. Most recurrences happened within the first year: a separate meta-analysis of 6 trials found that 34% of antibiotic-treated patients required delayed appendectomy within one year 3. Other studies report lower short-term rates: one prospective study found that 12.2% of patients needed readmission and surgery within one year 6. The risk of recurrence is a key consideration when choosing between antibiotics and surgery.
What to ask your doctor
- Based on my CT scan and symptoms, am I a good candidate for antibiotic therapy for uncomplicated appendicitis?
- What is my personal risk of recurrence or needing surgery later if I choose antibiotics?
- How will we monitor me for recurrence if I choose antibiotics instead of surgery?
- What are the pros and cons of antibiotics versus surgery for my specific health situation?
