Summary
Ruptured pyogenic liver abscess presents with septic shock and abdominal pain, distinct from non-ruptured cases. Prompt surgical intervention is crucial for survival, as this condition has a higher mortality rate.
Area of Science:
- Hepatology
- Infectious Diseases
- Surgical Gastroenterology
Background:
- Pyogenic liver abscess (PLA) is a serious condition requiring prompt diagnosis and management.
- Ruptured PLA presents unique clinical challenges compared to non-ruptured abscesses.
Purpose of the Study:
- To investigate the clinical features, treatment, and outcomes of ruptured pyogenic liver abscess.
- To compare ruptured PLA cases with non-ruptured PLA to identify distinguishing characteristics and prognostic factors.
Main Methods:
- A retrospective study of 424 patients with PLA, focusing on 23 cases of ruptured abscess.
- Analysis of clinical manifestations, laboratory findings, etiology, concurrent conditions (e.g., diabetes mellitus), and treatment outcomes.
- Statistical analysis using chi-squared and Student's t-tests for qualitative and quantitative data, respectively.
Main Results:
- Ruptured PLA cases showed higher levels of bilirubin, blood glucose, and aspartate aminotransferase.
- Septic shock and diffuse abdominal pain were key indicators of rupture.
- Klebsiella pneumoniae was the most common pathogen; diabetes mellitus was prevalent in ruptured cases (60.9%).
- Surgical drainage was essential for survival, with a significantly higher mortality rate in the ruptured group (43.5%) versus non-ruptured (15.5%).
Conclusions:
- Ruptured pyogenic liver abscess should be suspected in patients presenting with septic shock, diffuse abdominal pain, and elevated liver enzymes and glucose.
- Aggressive surgical management is the definitive treatment for ruptured PLA.
- Early recognition and intervention are critical to reduce the high mortality associated with ruptured liver abscess.
