    A retrospective study found that a careful history, physical exam, and basic tests can lower negative appendectomy rates. This approach achieved a 7.4% negative exploration rate without increasing perforations.

    Area of Science:

    • Surgical outcomes
    • Gastrointestinal surgery

    Background:

    • Acute appendicitis is a common surgical emergency.
    • Negative exploration rates in appendectomy vary and impact healthcare costs and patient outcomes.

    Purpose of the Study:

    • To evaluate the incidence of negative explorations in appendectomies performed using a conservative diagnostic approach.
    • To determine if a lower negative exploration rate can be achieved without increasing perforation rates.

    Main Methods:

    • Retrospective analysis of 282 appendectomy cases for suspected acute appendicitis.
    • Review of patient history, physical examinations, and basic laboratory and X-ray studies.
    • No advanced diagnostic imaging or tests were utilized.

    Main Results:

    Related Experiment Videos

    • An overall negative exploration rate of 7.4% was observed.
    • This rate is significantly lower than previously reported literature values.
    • The incidence of perforation remained at 22%, showing no significant increase.

    Conclusions:

    • A conservative diagnostic strategy, relying on clinical assessment and basic tests, can effectively reduce negative appendectomy rates.
    • The accepted negative exploration rate of 15%-20% may be reduced through meticulous clinical evaluation.
    • This approach offers a cost-effective method for improving appendectomy outcomes.
