Early Vs Late Liver Retransplantation: Different Characteristics and Prognostic Factors

Area of Science:

• Hepatology
• Transplantation Surgery
• Gastroenterology

Background:

• East Asia has a high prevalence of hepatitis B, a leading indication for living donor liver transplantation.
• Increasing organ shortages necessitate a focus on liver retransplantation (ReLT).
• This study addresses the unique challenges of early versus late ReLT in East Asian populations.

Purpose of the Study:

• To compare early and late liver retransplantation outcomes.
• To identify specific circumstances and disease backgrounds influencing ReLT in East Asians.
• To determine prognostic factors for ReLT success.

Main Methods:

• Retrospective analysis of 51 patients who underwent ReLT between 1996 and 2015.
• Investigation of clinical characteristics, indications, mortality causes, survival rates, and prognostic factors.
• Multivariate analysis to identify risk factors for mortality.

Main Results:

• One-year survival rates were comparable: 51.5% for early ReLT (n=18) and 50.1% for late ReLT (n=33).
• Early ReLT associated with higher rates of continuous venovenous hemodialysis, mechanical ventilation, and longer pre-transplant ICU stays.
• Late ReLT involved longer operation times and greater intraoperative blood loss; higher C-reactive protein predicted mortality in early ReLT, while higher total bilirubin predicted mortality in late ReLT.

Conclusions:

• Early ReLT patients are often sicker pre-transplantation, requiring aggressive management of infectious diseases.
• Late ReLT presents greater technical challenges and necessitates timely intervention before significant increases in total bilirubin levels.
