Objective: To describe the characteristics of liver abscesses, bacteriology and evaluate the results of percutaneous drainage. Methods: Retrospective observational study, were included 23 patients with liver abscess, hospitalized and underwent percutaneous drainage, in the Hospital de Clinicas (University school hospital) FCM-UNA, from June 2014 to June 2016. Results: They were located in the right lobe 82.6%, cryptogenic were 26%, 21.7% biliary caused by bacteremia 17.4%, 13% diverticulitis, liver cyst infected 13%, gastric fistula 4.3 % and colon cancer 4.3%, the culture was positive in 69.56%, Klebsiella was isolated in 17.3%, it was found in 95.6% leukocytosis and elevated alkaline phosphatase in 69.56%. The result was satisfactory drainage in 82.6%, with the placement of a single catheter. The average length of stay was 19.3 days and mortality was 4.3%. Conclusion: Most abscesses were located in the right lobe and the most frequent cause was cryptogenic. The most frequently isolated germ was Klebsiella pneumoniae. Percutaneous drainage was successful in most patients and the mortality round was low. Percutaneous drainage is a simple and safe technique, which could now be considered the "gold standard" in the treatment of liver abscesses.
