Abstract:
Pyogenic liver abscess is a serious condition with a high mortality rate. New diagnostic techniques have improved the diagnostic accuracy. Alternative therapeutic methods to open surgical drainage, such as percutaneous drainage and in certain cases antibiotics alone, are now available. Have changes in management of liver abscesses at our hospital improved the outcome? Two 5-year periods (I: n = 12; II: n = 14) were compared concerning diagnostic procedures, principles of treatment, and outcome. A shift from scintigraphy in the first period (I) to ultrasonography (US) in the second period (II) as prime diagnostic procedure was obvious. In I open surgical drainage dominated. 4/12, major surgical risks, were treated by anti-aerobic drugs alone, and died. In II US-guided percutaneous drainage was performed in 7/14, together with antibiotics active against aerobes as well as anaerobes, without complications. 4/14 were treated by an antibiotic combination alone and only 3/14 were treated by open surgical drainage. The change in management during these two periods has resulted in improved diagnostic and therapeutic routines as demonstrated by reduction in mortality rate.
Insights
Improved diagnostic and treatment strategies for pyogenic liver abscesses have significantly reduced mortality rates. The study highlights the shift towards ultrasonography (US) and percutaneous drainage, leading to better patient outcomes.
Area of Science:
- Hepatology
- Infectious Diseases
- Surgical Management
Background:
- Pyogenic liver abscesses present a significant clinical challenge with high mortality.
- Advancements in diagnostic imaging and therapeutic interventions offer alternatives to traditional surgical approaches.
Purpose of the Study:
- To evaluate the impact of evolving management strategies on patient outcomes for pyogenic liver abscesses.
- To compare diagnostic procedures, treatment principles, and mortality rates between two distinct 5-year periods.
Main Methods:
- Retrospective comparison of two 5-year cohorts (Period I and Period II) of patients with pyogenic liver abscess.
- Analysis of diagnostic modalities (scintigraphy vs. ultrasonography) and treatment approaches (surgical drainage, percutaneous drainage, antibiotics alone).
Main Results:
- A notable shift occurred from scintigraphy to ultrasonography (US) as the primary diagnostic tool.
- Period II saw increased utilization of US-guided percutaneous drainage and antibiotic therapy, with a decrease in open surgical drainage.
- Mortality rates were reduced in Period II compared to Period I, correlating with changes in management.
Conclusions:
- The adoption of advanced diagnostic techniques like US and less invasive treatments such as percutaneous drainage has demonstrably improved outcomes for pyogenic liver abscesses.
- Updated therapeutic routines, including targeted antibiotic regimens and minimally invasive procedures, are crucial for reducing mortality in this serious condition.
