Liver Transplantation from Voluntary Organ Donor System in China: A Comparison between DBD and DCD Liver Transplants

الملخص EN

Background.

In China, the cases of liver transplantation (LT) from donation after citizens’ death have rose year by year since the citizen-based voluntary organ donor system was initiated in 2010.

The objective of our research was to investigate the early postoperative and late long-term outcomes of LT from donation after brain death (DBD) and donation after circulatory death (DCD) according to the current organ donation system in China.

Methods.

Sixty-two consecutive cases of LT from donation after citizens’ death performed in our hospital between February 2012 and June 2017 were examined retrospectively for short- and long-term outcomes.

These included 35 DCD LT and 27 DBD LT.

Result.

Subsequent median follow-up time of 19 months and 1- and 3-year graft survival rates were comparative between the DBD group and the DCD group (81.5% and 66.7% versus 67.1% and 59.7%; P=0.550), as were patient survival rates (85.2% and 68.7% versus 72.2% and 63.9%; P=0.358).

The duration of ICU stay of recipients was significantly shorter in the DBD group, in comparison with that of the DCD group (1 versus 3 days, P=0.001).

Severe complication incidence (≥grade III) after transplantation was identical among the DBD and DCD groups (48.1% versus 60%, P=0.352).

There was no significant difference in postoperative mortality between the DBD and DCD groups (3 of 27 cases versus 5 of 35 cases).

Twenty-one grafts (33.8%) were lost and 18 recipients (29.0%) were dead till the time of follow-up.

Malignancy recurrence was the most prevalent reason for patient death (38.8%).

There was no significant difference in incidence of biliary stenosis between the DBD and DCD groups (5 of 27 cases versus 6 of 35 cases, P=0.846).

Conclusion.

Although the sample size was small to some extent, this single-center study first reported that LT from DCD donors showed similar short- and long-term outcomes with DBD donors and justified the widespread implementation of voluntary citizen-based deceased organ donation in China.

However, the results should be verified with a multicenter larger study.
