The extension of liver transplantation to new oncologic indications might exacerbate the shortage of grafts. Living donor liver transplantation (LDLT) may emerge as a viable resource, although its diffusion in the Western world is still very limited. Several groups have advocated for minimizing the impact on donors by reducing the extent of donor hepatectomy, i.e., shifting from right-lobe to left-lobe or left-lateral segment donation ("shift-to-left"). This is particularly relevant when dealing with non-established indications and could make it more acceptable both for potential donors and for the recipients. Left grafts can be transplanted straightforward, despite a higher risk of small-for-size syndrome, or they can be used in the setting of dual-graft LDLT or RAPID procedures, despite technical complexity. This review will expose the most relevant features of each technique, highlighting their strengths and pitfalls and focusing on outcomes. This wide set of tools should be available at high-volume transplant centers, to propose the best technique to adapt to donor-recipient matching.
