Summary
Percutaneous drainage is safe and effective for pyogenic liver abscesses, including single, multiple, and multiloculated types. This minimally invasive procedure shows high success rates regardless of abscess complexity.
Area of Science:
- Interventional Radiology
- Hepatology
- Infectious Diseases
Background:
- Pyogenic liver abscesses (PLAs) are serious infections requiring effective treatment.
- Percutaneous drainage is a primary intervention for PLA management.
- Assessing drainage effectiveness across different PLA types is crucial for treatment optimization.
Purpose of the Study:
- To compare the efficacy of percutaneous abscess drainage for various pyogenic liver abscess classifications.
- To evaluate outcomes in single, single multiloculated, multiple, and multiple multiloculated liver abscesses.
Main Methods:
- Retrospective analysis of 109 patients with 149 PLAs treated with percutaneous drainage over 11 years.
- Patients categorized into single vs. multiple abscess groups, and further into simple vs. multiloculated subgroups.
- Technical success (catheter placement) and clinical success (symptom improvement) were primary endpoints.
Main Results:
- High technical success rates (94-96%) across all abscess types (single, multiple, simple, multiloculated).
- Clinical success rates were also high (87-92%) irrespective of abscess complexity or multiplicity.
- No significant differences in hospital stay or major complications/mortality were observed between groups.
Conclusions:
- Percutaneous drainage is a safe and highly effective treatment for pyogenic liver abscesses.
- The procedure's success is independent of abscess complexity (single, multiple, multiloculated).
- This minimally invasive approach offers reliable outcomes for diverse PLA presentations.
