    Many appendectomies are unnecessary, leading to significant costs and complications. Further research is needed to reduce negative appendectomy rates while ensuring patient safety and accurate diagnoses.

    Area of Science:

    • Surgical outcomes
    • Diagnostic accuracy in abdominal surgery

    Background:

    • Negative appendectomy, where the appendix is removed but found to be normal, presents diagnostic and economic challenges.
    • Many conditions can mimic acute appendicitis, complicating surgical decision-making.

    Purpose of the Study:

    • To evaluate the outcomes and implications of negative appendectomies in a prospective patient cohort.
    • To identify potential strategies for reducing the rate of unnecessary appendectomies.

    Main Methods:

    • A prospective study involving 107 patients undergoing appendectomy with negative findings.
    • Analysis of symptom causes, diagnostic clarity, complication rates, and long-term follow-up.

    Main Results:

    • Appendectomy was unnecessary in 94% of patients.

  • A cause for symptoms was identified in only 43 patients (32 intraoperatively, 11 postoperatively).
  • A substantial financial cost and a 14% complication rate were associated with negative appendectomies. Later diagnoses occurred in 9.3% and persistent pain in 12.1% of patients.

    • Conclusions:

    • Negative appendectomies are frequent and associated with considerable morbidity, cost, and diagnostic uncertainty.
    • Careful examination of all abdominal organs during surgery is crucial when the appendix appears normal.
    • Regular patient follow-up is essential after negative appendectomy to ensure timely diagnosis and management of persistent symptoms.
