Our objective was to evaluate the clinical success rates of percutaneously drained intra-abdominal abscesses using a risk stratification score for severely ill patients (APACHE III; Acute Physiology, Age, Chronic Health Evaluation). In 75 patients CT-guided percutaneous abscess drainage was performed to treat intra-abdominal abscesses. The clinical success rate based on a 1-year follow-up was correlated with abscess etiology, size, and structure, as well as with the initial APACHE III score. Clinical success, i.e., the complete removal of the abscess without surgical treatment, was observed in 62 of 75 patients (83%). Abscess size (<200 cm(3)) and abscesses with a simple structure correlated with higher clinical success rates. Patients presenting with APACHE III scores below 30 were treated by percutaneous abscess drainages (PAD) alone significantly more often than patients presenting with higher APACHE scores. The percutaneous drainage of intra-abdominal abscesses shows good long-term results as long as abscesses are singular, small (<200 cm(3)), and located in well accessible regions in combination with low APACHE scores (<30).
