Overview
Liver abscesses are localized collections of pus within the liver parenchyma, often caused by bacterial infections, and can present with symptoms such as fever, abdominal pain, and jaundice 1.Diagnosis
Clinical Presentation: Fever, right upper quadrant pain, jaundice, and signs of systemic infection 1.
Imaging: Ultrasound and CT scans are crucial for identifying abscesses and assessing their size and number 1.
Laboratory Tests: Elevated liver enzymes, leukocytosis, and positive blood cultures when feasible 1.
Definitive Diagnosis: Often requires imaging confirmation and sometimes percutaneous aspiration for microbiological analysis 1.Management
Antibiotics: Initial broad-spectrum coverage followed by targeted therapy based on culture results (specific drug classes not detailed in 1).
Percutaneous Drainage: Recommended for larger abscesses or those not responding to antibiotics 1.
Surgical Intervention: Reserved for cases refractory to medical and percutaneous management 1.
Supportive Care: Includes fluid management, nutritional support, and monitoring for complications 1.Special Populations
Pregnancy: Management requires careful consideration of teratogenic risks; antibiotics with safer profiles during pregnancy should be prioritized 1.Key Recommendations
Use imaging (ultrasound, CT) for definitive diagnosis of liver abscesses (Evidence: Expert opinion 1).
Initiate broad-spectrum antibiotics and tailor based on culture results (Evidence: Expert opinion 1).
Consider percutaneous drainage for large or unresponsive abscesses (Evidence: Expert opinion 1).
In pregnant patients, select antibiotics with minimal teratogenic risk (Evidence: Expert opinion 1).References
