This study reviewed liver abscess cases, finding a shift from amoebic to pyogenic abscesses over time. Improved treatment strategies led to zero mortality in later cases, highlighting effective management of liver abscesses.

Area of Science:

Hepatology
Infectious Diseases
Internal Medicine

Background:

Liver abscesses represent a significant clinical challenge, with varying etiologies and treatment outcomes.
Understanding the changing trends in liver abscess types and their associated risk factors is crucial for effective patient management.

Purpose of the Study:

To review liver abscess cases, analyze trends in etiology (amoebic vs. pyogenic), and evaluate treatment outcomes.
To identify demographic, clinical, and laboratory features associated with different types of liver abscesses.

Main Methods:

Retrospective review of 40 consecutive liver abscess cases at Singapore General Hospital (1978-1983).
Analysis of patient demographics, clinical presentation, laboratory investigations, abscess characteristics, treatment modalities, and outcomes.

Comparison of findings between amoebic and pyogenic abscesses, and between early and later case series.

Main Results:

A shift from amoebic (60%) to pyogenic (50%) liver abscesses was observed over the study period.
Indian ethnicity and male gender showed a predilection; peak incidence was in the 40-70 age group.
Pyogenic abscesses were frequently polymicrobial (Klebsiella, E. coli), often multiple, and associated with higher initial mortality (30%) compared to amoebic abscesses.

Conclusions:

Liver abscess etiology can shift over time, necessitating ongoing epidemiological surveillance.
Prompt diagnosis and appropriate management, including antibiotics and drainage when indicated, are critical.
Improved treatment strategies implemented after 1981 resulted in a significant reduction in mortality, demonstrating effective management of liver abscesses.
