Pyogenic liver abscesses are often caused by biliary tract disease. While percutaneous drainage can be effective, open drainage combined with definitive procedures showed no mortality in this study.

Area of Science:

  • Hepatology
  • Infectious Diseases
  • Surgical Gastroenterology

Background:

  • Pyogenic liver abscess (PLA) is a serious intra-abdominal infection.
  • Etiology and optimal management strategies for PLA require ongoing investigation.

Purpose of the Study:

  • To evaluate trends in etiology of pyogenic liver abscess.
  • To assess the efficacy of percutaneous drainage versus open drainage for PLA treatment.

Main Methods:

  • Retrospective review of 24 patients treated for pyogenic liver abscess.
  • Analysis of causative organisms, primary etiologies, and treatment outcomes.
  • Comparison of mortality rates between percutaneous drainage and open drainage with definitive procedures.

Main Results:

  • Biliary tract disease was the most frequent etiology (29%).
  • Klebsiella (33%) and Enterococcus (29%) were the predominant pathogens.
  • Overall mortality was 25%; however, no deaths occurred with open drainage plus definitive surgery (e.g., cholecystectomy, bowel resection).

Conclusions:

  • Biliary tract disease remains a significant cause of pyogenic liver abscess.
  • Percutaneous drainage alone is recommended only for select PLA patients.
  • Combined open drainage and definitive surgical procedures offer the best survival outcomes for pyogenic liver abscess.
