Background: Pyogenic liver abscesses have become common in emergency departments (EDs) in recent years in Shanghai, China due to a variety of risk factors contributory to the disease.
Objective: To review our experience in managing pyogenic liver abscesses to aid in the current management of this complex condition.
Methods: This retrospective study was conducted to collect and analyze information from adult patients diagnosed with liver hepatic abscesses who were admitted to Ren Ji Hospital during the period from January 1, 2010 to December 31, 2015. The demographic data, etiology, underlying diseases, clinical presentation, imaging features, laboratory examinations, microbiological tests, treatment, and clinical outcomes were analyzed.
Results: The data of a total 105 patients were retrospectively analyzed. The mean age of the patients was 62.0 ± 13.5 years. The etiology was predominantly hepatobiliary disease (43/105, 40.1%) or diabetes mellitus (42/105, 40.0%). During hospitalization, 12 patients (11.4%) with septic shock required intensive care. One patient died, yielding a 0.9% fatality rate. In addition to empiric antimicrobial therapy, 66/105 (62.9%) patients underwent ultrasound-guided percutaneous drainage of the liver abscess at diagnosis. Only 3 patients required surgical intervention. Bacterial culture of pyogenic fluids revealed 25 positive results of 66 cases (37.9%). Among them, Klebsiella pneumoniae was the primary pathogen detected in 15 cases (60.0%).
Conclusions: Pyogenic liver abscesses have become common in EDs in Shanghai, China. The early recognition of the disease, prompt use of empirical antimicrobial therapy, initiation of drainage in the appropriate patients, and controlling the underlying conditions were crucial for preventing severe sepsis and improving the outcome.
