Background
This paper aims to demonstrate if Escherichia coli pyogenic liver abscess (ECPLA) results in adverse outcomes compared to Klebsiella pneumoniae PLA (KPPLA).
Methods
A retrospective review of all patients admitted at a tertiary hospital in Singapore from 2003 to 2011 was performed. Patients with age <18 years, amoebic liver abscess, infected liver cyst, culture negative abscess or ruptured liver abscess requiring urgent surgical intervention were excluded. Only patients with blood or pus culture confirmation of ECPLA (n = 24) or KPPLA (n = 264) were included. Median length of hospital stay, failure of non-operative therapy and 30-day mortality are the reported outcomes.
Results
ECPLA affects older patients (68 vs. 62 years, p = 0.049). Ischemic heart disease was more common in ECPLA (29 vs. 14 %, p = 0.048) and there was no difference in diabetic state (42 vs. 38 %, p = 0.743). ECPLA is more commonly associated with hyperbilirubinemia (60 vs. 34 µmol/L, p = 0.003), increased gamma-glutamyl transpeptidase (236 vs. 16 IU/L, p = 0.038) and gallstones (58 vs. 30 %, p = 0.004). KPPLA are larger in size (6 vs. 4 cm, p = 0.006) and had percutaneous drainage (PD) more frequently (64 vs. 42 %, p = 0.034). There was no difference in median hospital stay (14 vs. 14 days, p = 0.110) or 30-day mortality (17 vs. 10 %, p = 0.307) between ECPLA and KPPLA. Among patients with ECPLA, antibiotic treatment with PD appeared to have higher mortality compared to antibiotic treatment alone (30 vs. 7 %) but this was not significant (p = 0.272).
Conclusion
In the setting of multimodal care, outcomes of ECPLA are comparable to KPPLA.
