    Area of Science:

    • Hepatology
    • Infectious Diseases
    • Surgical Infections

    Background:

    • Liver abscess is a serious intra-abdominal infection with significant morbidity and mortality.
    • Historical etiologies include amebic infections and appendicitis, with varying roles over time.
    • The advent of antibiotics and advanced imaging has influenced diagnosis and treatment.

    Purpose of the Study:

    • To compare the clinical course and etiologies of liver abscess over a 12-year period with a historical cohort.
    • To analyze trends in causative organisms and clinical presentation.
    • To evaluate the impact of diagnostic advancements on patient outcomes.

    Main Methods:

    • Retrospective review of 25 patients treated for liver abscess over 12 years.
    • Comparison with a previous series of 22 patients from 1968.

    Related Experiment Videos

  • Analysis of clinical data, including etiology, presentation, diagnosis, and outcomes.
  • Literature review of liver abscess management over the past four decades.

    • Main Results:

    • Decreased incidence of amebic abscess and appendicitis as etiologies.
    • Increased recognition of immunologic deficiencies and anaerobic bacteria as causes.
    • Shift towards a more chronic clinical presentation.
    • Marked reduction in mortality rates over the past two decades.
    • Earlier diagnosis attributed to liver scanning and other imaging modalities.

    Conclusions:

    • Etiology of liver abscess is evolving, with a rise in non-amebic and non-appendiceal causes.
    • Improved diagnostic imaging techniques are crucial for timely and accurate diagnosis.
    • Advances in diagnostic and supportive care have led to decreased mortality.
    • Continued utilization of advanced imaging and perioperative care is recommended.
