Pyogenic liver abscess treatment has evolved. Early diagnosis with imaging and minimally invasive methods like antibiotics, aspiration, or catheter drainage are effective alternatives to open surgical drainage.

Area of Science:

  • Hepatology
  • Infectious Diseases
  • Surgical Innovation

Background:

  • Open surgical drainage was historically the primary treatment for pyogenic liver abscess.
  • Advancements in diagnostic imaging and interventional techniques prompt re-evaluation of treatment strategies.

Purpose of the Study:

  • To assess the efficacy of non-operative and minimally invasive treatments for pyogenic liver abscess.
  • To compare outcomes of antibiotics, aspiration, and percutaneous catheter drainage versus open surgical drainage.

Main Methods:

  • Retrospective review of 54 patients diagnosed with pyogenic liver abscess.
  • Analysis of treatment modalities including antibiotics, diagnostic aspiration, percutaneous catheter drainage, and open surgical drainage.
  • Evaluation of patient recovery, complications, and mortality rates.

Main Results:

  • Antibiotics with aspiration led to uneventful recovery in 79% of patients; 6 required further drainage.
  • Percutaneous catheter drainage resulted in recovery for 83% of patients; 4 needed open surgery.
  • Four patients were successfully treated with antibiotics alone. Mortality was low (2%), associated with treatment failure.

Conclusions:

  • Pyogenic liver abscess can be effectively managed with broad-spectrum antibiotics combined with aspiration or percutaneous catheter drainage.
  • Open surgical drainage should be reserved for cases refractory to less invasive methods or for concurrent surgical indications.
  • Early diagnosis and targeted minimally invasive interventions improve patient outcomes for pyogenic liver abscess.
