LDLT covers all standard indications for liver transplantation, and the results are similar or even better than for standard DDLT. Due to the donor shortage and long waiting time, LDLT has become a relevant option for patients with liver tumors, provided the expected five-year survival rate is comparable to that of patients receiving a DDLT. Nowadays, LDLT offers the possibility to extend the standard morphometric selection by considering the biological parameters. In the setting of LDLT, we are not only faced with surgical morbidity in the donor, but long-term non-medical problems like psychological complications and financial burden also have to be considered. On the other hand, the benefits to the donor are mainly social and psychological. In LDLT, the donor's altruism is the fundamental ethical principle and it is based on the principles of (1) beneficence (doing good), (2) non-maleficence (avoiding harm), (3) respect for autonomy, and (4) respect for justice (promoting fairness). On top of that, the concept of double equipoise of living organ donation evaluates the relationship between the recipient's need, the donor's risk, and the recipient's outcome. It considers each donor-recipient pair as a unit, analyzing whether the specific recipient's benefit justifies the specific donor's risk in particular oncologic indications. In this light, it is essential to seek adequate informed consent focused on risk, benefits and outcome benefits of both donor and recipient supported by an independent living donor advocate. Finally, the transplant team must protect donors from donation if harm does not justify the expected benefit to the recipient.
LDLT 涵盖了所有肝移植的标准适应证,其结果与标准 DDLT 相似甚至更好。由于供体短缺和等待时间长,LDLT 已成为肝肿瘤患者的一种相关选择,只要预期的五年生存率与接受 DDLT 的患者相当。如今,LDLT 提供了通过考虑生物学参数来扩展标准形态学选择的可能性。在 LDLT 中,我们不仅面临供体的手术发病率,而且还必须考虑长期的非医疗问题,如心理并发症和经济负担。另一方面,供体的获益主要是社会和心理方面的。在 LDLT 中,供体的利他主义是基本的伦理原则,它基于(1)善行(做好事)、(2)不伤害(避免伤害)、(3)尊重自主权和(4)尊重正义(促进公平)的原则。除此之外,活体器官捐献的双重平衡概念评估了受者需求、供者风险和受者结果之间的关系。它将每个供者-受者对视为一个单位,分析在特定的肿瘤学适应证中,特定受者的获益是否证明了特定供者的风险是合理的。从这个角度来看,寻求充分的知情同意至关重要,重点是关注风险、供者和受者的获益,同时由独立的活体供者倡导者提供支持。最后,如果对供者造成的伤害不能证明对受者的预期获益合理,移植团队必须保护供者免受捐献。
