Summary
Percutaneous abdominal abscess drainage is best for simple, unilocular abscesses, requiring careful CT guidance and catheter care to prevent sepsis. This method may be less effective than previously reported, with surgery preferred for complex cases.
Area of Science:
- Gastroenterology
- Interventional Radiology
Background:
- Percutaneous abdominal abscess drainage (PAAD) is a minimally invasive technique.
- Its efficacy and ideal indications require further clarification.
Purpose of the Study:
- To evaluate the effectiveness and optimal use of PAAD.
- To identify factors influencing PAAD success and complications.
Main Methods:
- Retrospective review of 21 patients undergoing PAAD.
- Analysis of abscess characteristics, imaging, and outcomes.
Main Results:
- PAAD is suitable for unilocular, non-septated abscesses with safe access.
- Computerized tomographic (CT) scans are crucial for safe access and identifying synchronous abscesses.
- PAAD is recommended for postsurgical abscesses, not spontaneous ones.
- Frequent catheter irrigation (every 4-6 hours) with high antibiotic levels is vital to prevent sepsis.
- The procedure can cause morbidity, and its efficacy may be lower than previously suggested.
Conclusions:
- PAAD is a viable option for select abdominal abscesses, particularly postsurgical ones.
- Careful patient selection, imaging, and meticulous catheter management are critical for success and complication avoidance.
- Surgical drainage remains superior for multiple, viscous, inaccessible, spontaneous, or refractory abscesses.
