Summary
Liver transplants from non-heart-beating donors (NHBDs) show similar patient survival but higher primary nonfunction and lower allograft survival compared to heart-beating donors (HBDs). Cautious pursuit is encouraged to address donor shortages.
Area of Science:
- Transplantation Surgery
- Organ Donation
- Hepatology
Background:
- Non-heart-beating donors (NHBDs) offer a potential solution to increase the organ donor pool.
- Liver transplantation from NHBDs is less common, with limited reported outcomes.
- This study evaluates liver transplants from controlled NHBDs.
Purpose of the Study:
- To compare outcomes of liver transplantation using organs from controlled non-heart-beating donors (NHBDs) versus heart-beating donors (HBDs).
- To assess differences in complications, patient survival, and allograft survival between the two donor types.
Main Methods:
- A retrospective comparison of 19 liver transplants from controlled NHBDs and 364 from HBDs between 1993 and 1999.
- Evaluation of donor and recipient characteristics, post-transplant complications, and survival rates.
- Statistical analysis to compare outcomes between NHBD and HBD groups.
Main Results:
- No significant differences in hepatic artery, portal vein, or biliary complications were observed.
- Primary nonfunction rate was higher in the NHBD group (10.5%) compared to the HBD group (1.3%; P = .04).
- Patient survival was similar (72.6% vs. 84.8%; P = .36), but allograft survival was lower in recipients of NHBD livers (53.8% vs. 80.9%; P = .007).
Conclusions:
- Liver transplantation from controlled NHBDs yields comparable patient survival and post-transplant complication rates to HBDs.
- Higher rates of primary nonfunction and reduced allograft survival necessitate cautious advancement of NHBD liver transplantation.
- NHBD liver transplantation remains a promising strategy to mitigate the critical shortage of donor organs.
