The conventional wisdom that appendicitis requires immediate surgical removal is being challenged by mounting evidence that many patients can avoid the operating room entirely. This shift could spare hundreds of thousands of people annually from unnecessary surgery and its associated risks, recovery time, and costs. Two landmark clinical trials have demonstrated that antibiotic therapy successfully treats uncomplicated acute appendicitis in roughly half to two-thirds of patients over multiple years. The European APPAC trial found that 61% of patients treated with a 10-day antibiotic regimen (intravenous ertapenem followed by oral levofloxacin and metronidazole) remained surgery-free at five years. The American CODA trial, which included more complex cases with appendicoliths, showed 51% of antibiotic-treated patients avoided appendectomy at three to four years. Both studies confirmed antibiotics were non-inferior to surgery for initial treatment outcomes. This represents a paradigm shift from the historical 'emergency surgery or bust' approach that has dominated appendicitis care for over a century. The findings suggest that for many patients, antibiotics offer a viable first-line treatment that preserves the appendix while avoiding surgical complications like infection, bleeding, or bowel obstruction. However, the approach requires careful patient selection through CT imaging to confirm uncomplicated disease and exclude perforation or abscess formation. The durability of antibiotic treatment—maintaining effectiveness in roughly half of patients years later—indicates this conservative approach could become standard care for appropriately selected cases, fundamentally changing how emergency departments and surgeons approach one of the most common surgical emergencies.
