Antibiotics are a safe and effective alternative to surgery for uncomplicated appendicitis in many patients, with lower long-term complication rates and similar quality of life at 10 years.
For more than a century, surgery has been the standard treatment for acute appendicitis. If your appendix became inflamed, it was removed. But growing evidence now shows that for uncomplicated acute appendicitis, antibiotics alone can be a safe and acceptable alternative for many people. A major 10-year follow-up study recently published in JAMA helps clarify the long-term pros and cons of both options.
Uncomplicated appendicitis means the appendix is inflamed but has not burst, formed an abscess, or caused widespread infection. In these cases, antibiotics may calm the infection and allow the appendix to heal without surgery.
What the Research Shows
The long-term follow-up of the APPAC trial tracked patients for 10 years after treatment. About 38% of patients treated with antibiotics had a confirmed recurrence of appendicitis during that time. That means over 60% did not have another episode. Importantly, more than half of patients who started with antibiotics avoided surgery altogether.
Complications were actually higher in the surgery group. Over 10 years, about 27% of patients who had their appendix removed experienced complications, compared with only 8.5% in the antibiotic group. Quality of life was similar in both groups, and cancer rates were low and not meaningfully different.
Pros and Cons of Antibiotics
Pros
- Avoids surgery and anesthesia
- Lower long-term complication rates
- Faster recovery for many patients
- Can often be treated as an outpatient
- Lower overall healthcare costs
Cons
- About 4 in 10 patients may have appendicitis return
- Some patients will still need surgery later
- Requires access to follow-up medical care
- Uncertainty may cause anxiety for some patients
For patients who never needed surgery after antibiotics, satisfaction was very high. More than 90% said they would choose antibiotics again.
Pros and Cons of Surgery
Pros
- Definitive treatment with no risk of recurrence
- Removes uncertainty about future appendicitis
- High satisfaction rates for many patients
Cons
- Higher complication rates over time
- Surgical risks such as infection or hernia
- Longer recovery and time away from work
- Higher upfront costs
Surgery remains the best option for patients with complicated appendicitis or those who strongly prefer a permanent solution.
The Bottom Line
Today, treating uncomplicated appendicitis is no longer about “right versus wrong.” Both antibiotics and surgery are medically acceptable choices with different risks and benefits. The best option depends on the patient’s values, access to care, and comfort with the possibility of recurrence. Shared decision-making between patients and clinicians is now the standard—and that is good news.
