Pyogenic liver abscess diagnosis and treatment have evolved. Percutaneous drainage offers an alternative to surgery, emphasizing careful diagnostic workup for better patient outcomes.

Area of Science:

  • Hepatology
  • Infectious Diseases
  • Radiology

Context:

  • Pyogenic liver abscess (PLA) diagnosis and management have undergone significant changes.
  • This study analyzes 50 PLA patients treated over 13 years.

Purpose:

  • To report a retrospective analysis of PLA diagnosis and treatment outcomes.
  • To evaluate the effectiveness of different diagnostic modalities and treatment strategies.

Summary:

  • Ultrasound, CAT scan, and angiography showed diagnostic sensitivities of 68%, 89%, and 75%, respectively.
  • The biliary tree was the origin in 46% of cases; 38% remained unknown.
  • Treatments included surgery (31 patients), percutaneous drainage (13), and antimicrobials alone (5).
  • Septic complications occurred in 40%, with an 8% mortality rate. Abscess recurrence was noted in seven patients, two with gallbladder carcinoma.

Impact:

  • Percutaneous drainage is a viable alternative to surgical intervention for PLA.
  • A thorough diagnostic workup is crucial for optimal PLA management.
  • Findings contribute to understanding PLA epidemiology, diagnostic accuracy, and treatment efficacy.
