title: [Pyogenic liver abscess. Experience with 50 cases].
abstract: During the last years the diagnosis and treatment of pyogenic liver abscess has changed substantially. The aim of this work is to report a retrospective analysis of 50 patients aged 24 to 87 years old, that presented with a pyogenic liver abscess and were treated in the last 13 years. The sensitivity for diagnosis of ultrasound examination, CAT scan and angiography was 68, 89 and 75% respectively. The origin of the abscess was detected at the biliary tree in 46% and remained unknown in 38%. Thirty one patients were operated, 13 were subjected to percutaneous drainage and 5 were treated only with antimicrobials. Forty percent of patients had a septic complication and 4 (8%) died. Mean hospital stay was 31 days for operated patients and 21 for the rest. The abscess recurred in seven patients and two of these had a gallbladder carcinoma. It is concluded that percutaneous drainage is an alternative to surgical treatment that must be accompanied by a careful diagnostic workup.
