ABSTRACT
ObjectiveTo explore the efficacy of an antibiotic ertapenem for the treatment of bacterial liver abscess. MethodThe clinical data of 134 hospitalized bacterial liver abscess patients were retrospectively analyzed to evaluate the clinical and bacteriological efficacy of ertapenem from March 2009-2011in our hospital. ResultFever was present in 122 (91％)cases,abdominal pain was complained in 70 (52.2％ ) cases and rigor in 66 (49.3％ ) cases.In 92(68.7％ ) cases the abscess was located in the right lobe of the liver.Leukocytosis and liver dysfunction were found in 73 cases(54.8％ ) and 84 cases (62.7％ ),respectively.Ultrasonography was the most effective diagnostic means for liver abscess.Fortyone cases(30.6％ )were treated conservatively with ertapenem and 82(61.2％ )were treated with ertapenem associated with percutaneous liver puncture aspiration and 11cases (8.2％ )were treated with ertapenem associated with surgery.The clinical success rate was respectively 89％,87.8％,90.9％.The average duration of medication and length of stay were respectively ( 7.0 ± 2.4 ) d and 14.2 d.Ninety-seven pathogens were isolated from samples and predominant strains were Klebsiella species.Bacterial eradication rate was 92.8％.The sensitivities of isolated bacteria to ertapenem were 94.8％.ConclusionsErtapenem administration is effective therapy for bacterial liver abscess.
