METHODS A total of 45 treatment-naïve patients treated with PC for early or very early stage HCCs were included in this retrospective study. The safety of PC was assessed by evaluating procedure-related complications and comparing hepatic function before and after the procedure. The effectiveness was assessed by evaluating technical success, LTP rates, and disease progression (DP) rates. Prognostic factors associated with LTP after PC were also analyzed. RESULTS Technical success and complete response were achieved in all patients (100%) by 1 month after PC. During a mean of 28.1±15.6 months of follow-up, the incidences of LTP and DP were 11.1% and 37.8%, respectively. The LTP-free and DP-free survival rates were 93.3% and 84.4% at 1 year and 88.9% and 62.2% at 2 years, respectively. Hepatic function was normalized within 3 months after PC. There were no major complications and only one minor complication of small hematoma. On univariate and multivariate analysis, minimal ablative margin less then 5 mm was the only significant risk factor associated with LTP. CONCLUSION PC is a safe and effective therapy for patients with early or very early stage HCC. Minimal ablative margin less then 5 mm was a significant prognostic factor for LTP.PURPOSE We aimed to evaluate the success and failure rates and minor and major complications of percutaneous drainage of retroperitoneal abscesses. METHODS Between 1990 and 2010, percutaneously drained 170 retroperitoneal abscesses in 150 patients (83 males, 67 females, median age 44.2 years, age range, 1-86 years) were included retrospectively. Percutaneous drainage of retroperitoneal abscesses was performed under the guidance of ultrasonography an
