Introduction: The use of lower volume liver grafts has the potential to expand the donor pool in adult-to-adult live donor liver transplantation (LDLT), but is associated with an increased risk for small for size syndrome (SFSS). We investigated the long-term outcomes of LDLT recipients who developed SFSS and examined the efficacy of splenectomy as a strategy to modulate portal venous inflow.

Methods: Retrospective study of 520 adult-to-adult LDLT from April-2000 to June-2015. SFSS was diagnosed by graft dysfunction (persistent hyperbilirrubinemia >60[micro]mol/L and moderate/severe ascites) without an identifiable cause, or presence of intraoperative parenchymal congestion in the context of a low graft volume to portal flow.

Results: 32 LDLT recipients (6.2%) were diagnosed with SFSS. 26 recipients who developed SFSS and underwent splenectomy (group 1) were compared with 6 recipients who developed SFSS but did not undergo splenectomy (group 2) and then compared with 488 LDLT recipients without SFSS (group 3). Group 1 had a significantly higher graft survival (96.2/90.5/90.5% vs 33.3/16.7/16.7%, p=0.0001) and patient survival (100/100/100% vs 66.7/33.3/33.3%, p=0.0001) than Group 2 at 1/3/5 years respectively. Group 1 had a higher incidence of postoperative bacterial infections (46.2% vs 20.5%, p=0.004) and portal vein thrombosis (15.4% vs 2.3%, p=0.005) than group 3, but equivalent incidence of retransplantation (7.7% vs 6.1%, p=0.49) as well as graft and patient survival (96.2/90.5/90.5% vs 90.4/83.7/81.2% and 100/100/100% vs 92.9/86.4/84.7%) at 1/3/5 years.

Conclusion: In patients who develop SFSS after LDLT, splenectomy is a rescue therapy that decreases the chance of graft failure, achieving long-term outcomes comparable to LDLT recipients without SFSS. Poor outcomes in patients with SFSS without splenectomy highlight the importance of performing splenectomy as a method to modulate portal flow in these grafts.
