Treatment of P yogenic Liver Abscess by Percutaneous Needle Aspiration and / or Percutaneous Catheter Drainage
Abstract
-
BACKGROUND/AIMS: The availability of percutaneous needle aspiration and catheter drainage under the guidance of ultrasound, computed tomography (CT) have resulted in changes in diagnosis and treat-ment of pyogenic liver abscess. The present study was performed to investigate the usefulness opercutaneous aspiration and/or catheter drainage in the treatment of pyogenic liver abscess.
METHODS
This study was carried out retrospectively involving 42 consecutive patients with pyogenic liver abscess. The patients underwent percutaneous needle aspiration and/or catheter drainage under the guidance of ultrasound or CT for 7 years. The mean age of the patients was 55 years, and the mal to female ratio was 1.3:1. In the major part of patients, the abscess was located in the right lobe (61.9%) and single in number (69%). All patients were received broad spectrum antibiotics. Percuta neous needle aspiration was performed in 10 patients and percutaneous catheter drainage was em ployed in 36 patients including 4 patients who did not respond to needle aspiration.
RESULTS
Mean durations of antibiotic therapy and catheter drainage were 22 and 20 days, respectively. Percutaneous needle aspiration and catheter drainage were successful in 60% and 86.1% of patients, respectively Five patients who did not respond to percutaneous drainage had surgical drainage. Procedural com plications were noted in 11.1% of patients who underwent percutaneous catheter drainage but none after needle aspiration. One patient with biliary tract cancer died from sepsis and there was no death due to a complication of the procedures.
CONCLUSIONS
Our study suggests that percutaneous needle aspiration and/or catheter drainage under the guidance of ultrasound or computed tomography are safe and effective treatment modality for pygenic liver abscess.
