    Managing lung abscesses remains challenging. While antibiotics improved cure rates and reduced mortality initially, recent data show increased overall mortality, particularly with medical treatment, underscoring the need for timely surgical intervention.

    Area of Science:

    • Pulmonology
    • Thoracic Surgery
    • Infectious Diseases

    Background:

    • Lung abscess management presents ongoing challenges for clinicians.
    • A 50-year retrospective analysis (1928-1975) at Toronto General Hospital provides insights into treatment evolution.

    Purpose of the Study:

    • To analyze a 50-year experience with lung abscesses.
    • To define challenges and clarify treatment recommendations.
    • To illustrate the impact of antibiotics and understanding of aspiration/anaerobic infections.

    Main Methods:

    • Retrospective analysis of 413 lung abscess patients.
    • Categorization into three chronological treatment periods (1928-1954, 1955-1961, 1962-1975).
    • Comparison of cure rates and mortality between medical and surgical interventions over time.

    Main Results:

    • Antibiotics (1936-1954) increased cure rates (30% to 61%) and decreased mortality (47% to 21%).
    • Recent period (1962-1975) shows improved medical (73%) and surgical (89%) cure rates.
    • Overall mortality increased (12% to 25%), with medical treatment mortality rising (10% to 27%) while surgical mortality decreased (14% to 11%).

    Conclusions:

    • Despite advances, lung abscess management remains complex.
    • Increased mortality with medical therapy necessitates prompt surgical consideration when resolution is poor or complications arise.
    • Timely surgical intervention is crucial for improving outcomes in complicated lung abscess cases.
