Hepatic abscesses after liver transplant: 1997-2008

Area of Science:

• Hepatology
• Transplant Surgery
• Infectious Diseases

Background:

• Infectious complications, particularly hepatic abscesses, significantly contribute to morbidity and mortality following liver transplantation.
• Current management strategies for post-transplant hepatic abscesses are often extrapolated from non-transplant patients, highlighting a need for transplant-specific data.

Observation:

• A retrospective review identified 7 episodes of hepatic abscess in 5 liver transplant recipients over 11 years.
• Common predisposing factors included biliary anastomosis stricture, diabetes mellitus, and hepatic artery thrombosis.
• Escherichia coli and Aspergillus were the most common pathogens identified in liver aspirates.

Findings:

• Hepatic abscesses occurred 30-240 days post-transplant in recipients of deceased donor livers.
• Mortality was higher in liver transplant recipients with hepatic abscess compared to non-transplant patients.
• Despite drainage and antimicrobial therapy, two patients succumbed to liver and multiorgan failure.

Implications:

• Hepatic abscess is a rare but significant post-liver transplant complication associated with specific risk factors.
• Effective management requires prolonged antibiotic therapy and drainage to improve patient outcomes.
• Further research into transplant-specific risk factors and treatment protocols for hepatic abscess is warranted.
