Recommended management of a pyogenic liver abscess?

• A. Broad-spectrum antibiotics alone
• B. Open surgical drainage
• C. Broad-spectrum antibiotics with image-guided percutaneous drainage
• D. Percutaneous drainage alone

Answer: (C)

Effective management of a pyogenic liver abscess requires addressing both the infection and the source of pus. Start broad-spectrum IV antibiotics to cover enteric Gram-negative bacteria and anaerobes, then obtain image-guided drainage to remove the purulent material. Image-guided percutaneous drainage (via ultrasound or CT) is preferred because it is minimally invasive, has high success rates, and reduces morbidity compared with open surgery. Draining the abscess also improves antibiotic penetration and helps prevent ongoing sepsis.

Open surgical drainage is reserved for situations where percutaneous drainage isn’t feasible or has failed, or if there are other intra-abdominal problems that require surgery. Antibiotics alone are often insufficient for larger or loculated abscesses, and drainage without antibiotics misses ongoing systemic infection. So the best approach combines broad-spectrum antibiotics with image-guided percutaneous drainage.
