Split liver transplantation (SLT) represents a valuable strategy to increase the donor pool for liver transplantation. We report the first national experience with full left-full right SLT in a single center.

A retrospective analysis of the first 14 split liver transplantations performed in 2023 using 7 dead brain donor grafts was conducted. Demographics, technical aspects, early postoperative outcomes, and complications were analyzed, comparing left and right lobe recipients.

Seven left lobes and seven right lobes were transplanted. Right lobe recipients weighed more than left lobe recipients (63.3 kg vs 52.4 kg, p=0.04), while MELD scores were similar (15.4 vs 14.6, p=0.62). Overall patient and graft survival were both 86%. Left lobe recipients had lower patient and graft survival (71% vs 100%, p=0.13) and more vascular complications (43% vs 0%, p=0.04). Biliary complications occurred in 64% of all recipients (71% left vs 57% right, p=0.58). Left lobe recipients required significantly more interventions (9.7 vs 2.4, p=0.03) and had longer hospital stays (52.9 vs 30.1 days, p=0.01). The re-transplantation rate was 14%, exclusively in left lobe recipients.

Full left-full right SLT is a feasible procedure with acceptable outcomes, effectively doubling the number of liver grafts available for transplantation. Left lobe recipients experienced higher complication rates and lower survival, suggesting the need for careful recipient selection and specific technical considerations for left lobe transplantation.
