Pyogenic liver abscess--a neglected diagnosis

Area of Science:

• Medicine
• Hepatology
• Infectious Diseases

Background:

• Pyogenic liver abscess (PLA) is a serious intra-abdominal infection with significant morbidity and mortality.
• Historical data suggests challenges in PLA diagnosis and management, particularly in specific patient demographics.

Purpose of the Study:

• To review the clinical features, management, and outcomes of patients with pyogenic liver abscess.
• To identify factors contributing to mortality and to emphasize the importance of timely diagnosis.

Main Methods:

• Retrospective review of 25 patients with pyogenic liver abscess admitted to a single tertiary hospital.
• Analysis of patient demographics, clinical presentation, diagnostic methods, treatment, and outcomes.

Main Results:

• The overall mortality rate was 32%.
• All patients diagnosed prior to death survived, highlighting the critical role of early diagnosis.
• Patients with a history of biliary obstruction or surgery had a higher mortality rate (6/7 deaths).
• Older patients who died were significantly older than survivors, possibly due to misdiagnosis as malignancy.

Conclusions:

• High mortality from pyogenic liver abscess is primarily attributed to diagnostic delays and lack of clinical awareness, not inadequate treatment.
• Clinicians should maintain a high index of suspicion for liver abscess, even when initial investigations are inconclusive.
• Prompt diagnosis and intervention are crucial for improving patient survival rates in pyogenic liver abscess cases.
