Abstract :
Background: The use of ABO incompatible (ABOi) graft in living donor liver transplantation (LDLT) has not been an established procedure worldwide. Methods: Four hundred and eight adult LDLTs, using ABOi (n=19) and non-ABOi (n=389) grafts, were performed as a single center experience. Results: In ABOi-LDLT group (n=19), median isoagglutinin titer before plasma exchange (PE) at LDLT and after LDLT (max) was ×256, ×32 and ×32, respectively. Rituximab was given at 21.8±6.1 days before LDLT and PE was performed 3.7±1.6 times. Although ABOi-LDLTs had increased rate of splenectomy (89.4% vs. 44.7%, P 0.001) and lower portal venous pressure (PVP) at the end of surgery (13.8±1.1 vs. 16.9±0.2 mmHg, P=0.003), other operative factors including graft ischemic time, operative time and blood loss were not different between the groups. Although ABOi-LDLTs had increased incidence of cytomegalovirus infection (52.6% vs. 22.9%, P=0.007), other post-transplant complications including bacterial sepsis and acute rejection were not different between the groups. The 5-year graft survival rate was 87.9% in ABOi-LDLTs and 80.3% in non-ABOi-LDLTs (P=0.373). Conclusions: ABOi-LDLT could be safely performed, especially under rituximab-based protocol.
