RESUMO
Objective To compare the result of percutaneous or open drainage for muhilocular bacterial liver abscess. Methods The clinical data of 45 patients with multilocular bacterial liver abscess were reviewed retrospectively over the past 5 years. Twenty-one cases underwent B-us or CT-guided pereutaneons drainage (PD) and 24 received surgical drainage (SD) as the first-line treatment. The treatment outcomes in both groups were compared, and clinical end-points included time to defervescence, failure of treatment, secondary procedures, hospital stay, morbidity, and mortality. Results The time of defervesecnce was not statistically different between the two groups (4.85 day vs. 4.38 days, P＞0.05). However, patients in SD group suffered from less treatment failures (2 cases vs. 9 cases, P<0.05), less requirement for secondary procedures (1 cases vs. 11 cases,P<0.01), and shorter hospital stay (8 day vs. 11 days, P<0.05). There was no difference in morbidity or mortality rates between the two groups. Conclusions It was concluded that for multilocular liver abscess, SD provides better clinical outcomes than PD in terms of treatment success, number of secondary procedures, and hospital stay with comparable morbidity and mortality rates. SD should be considered as first-line treatment for multilocular bacterial liver abscesses.
