RESUMEN
Background: The outcomes of dual graft living donor liver transplantation (DGLDLT) in high acuity patients remain underreported. The objective of this study was to report long-term outcomes from a single center in this select group of patients. Methods: This was a retrospective review of patients who underwent DGLDLT between 2012 and 2017 (n = 10). High acuity patients were defined as patients with model for end stage liver disease (MELD) ≥30 or Child Pugh score ≥11. We looked at 90-day morbidity and mortality and 5-year overall survival (OS). Results: The median MELD score and Child Pugh score were 30 (26.7-35) and 11 (11-11.2). The median recipient weight was 105 (95.2-113.7) and ranged from 82 to 132 kg. Out of 10 patients, 4 (40%) required perioperative renal replacement therapy, and 8 (80%) required hospital admission for optimization. The estimated graft to recipient weight ratio (GRWR) with right lobe graft alone was <0.8 in all patients, between 0.75 and 0.65 in 5 (50%) patients, and <0.65 in 5 (50%) patients. The 90-day mortality was 3/10 (30%), and there were 3/10 (30%) deaths during long-term follow-up. Among 155 high acuity patients, the 1-year OS with standard LDLT, standard LDLT with GRWR <0.8, and DGLDLT was 82%, 76%, and 58%, respectively (P = 0.123). With a median follow-up of 40.6 (1.9-74.4) months, the 5-year OS for DGLDLT was 50%. Conclusion: The use of DGLDLT in high acuity patients should be prudent and low GRWR grafts should be considered a viable alternative in selected patients.
