Liver abscess: catheter drainage v/s needle aspiration

Abstract

Background: The aim of the study was to evaluate the clinical presentation, and to investigate the effectiveness of continuous catheter drainage in comparison to needle aspiration in the treatment of liver abscesses. Methods: This is a comparative study of 121 patients, presented in outpatient and emergency department at the hospital, randomized double blind trial was done and divide into two groups (percutaneous needle aspiration and pigtail catheter drainage.) about which surgeon did not knew about the division it was marked by evaluator. The effectiveness of either treatment was measured in terms of duration of hospital stay, days to achieve clinical improvement, reduction in abscess cavity size and total/near total resolution of abscess cavity. Results: The success rate was significantly better in catheter drainage group. The patients in pigtail catheter drainage group showed earlier clinical improvement and decrease in abscess cavity volume as compared to those who underwent percutaneous needle aspiration. Conclusions: Percutaneous catheter drainage is a better modality as compared to percutaneous needle aspiration especially in larger abscesses which are partially liquefied or with thick pus.
