[Therapy of pyogenic liver abscess]

Area of Science:

• Internal Medicine
• Gastroenterology
• Interventional Radiology

Background:

• Pyogenic liver abscess (PLA) is a serious intra-abdominal infection.
• Treatment options for PLA include antibiotics, percutaneous drainage, and surgical drainage.

Purpose of the Study:

• To evaluate the efficacy of percutaneous needle aspiration or drainage compared to surgical drainage for treating pyogenic liver abscesses.

Main Methods:

• Retrospective analysis of 11 patients with PLA treated between 1980 and 1986.
• Comparison of outcomes between patients treated with percutaneous methods (n=9) and surgical drainage (n=2).

Main Results:

• Percutaneous aspiration or drainage was successful in 7 out of 9 patients.
• Two patients initially treated with percutaneous methods required secondary surgical drainage.
• Both patients who underwent primary surgical drainage were successfully treated.

Conclusions:

• Percutaneous aspiration or drainage is a viable and effective first-line treatment for pyogenic liver abscess.
• Minimally invasive percutaneous techniques should be prioritized over surgical intervention for PLA management.
