title: Splitting livers - balancing the gain and the pain.
abstract: Division of donor livers has allowed effective expansion of the donor pool and has been associated with a reduction in the mortality of children awaiting liver transplantation. However, adult recipients of a split graft tend to have inferior transplant survival, compared with recipients of a whole graft. We have analysed the impact of the splitting programme at a particular centre on the life-years lost or gained in both adult and paediatric recipients. We estimate that at 1 year after transplantation, splitting livers has resulted in a gain of five life-years for the paediatric recipients with a loss of six adult patient years; at 5 years post-transplant, a gain of 25 life-years for the paediatric recipients balances a loss of 30 life-years for adult recipients. While this analysis is based on a number of assumptions, and so the results must be treated with caution, it does give rise to a number of ethical considerations which require open and public debate.
