SECTION 16. UPDATE ON EXPERIENCE IN PAIRED-EXCHANGE DONORS IN MFING DONOR MFER TRANSPLANTATION FOR ADULT PATIENTS AT ASAN MEDICAL CENTER

摘要

Background. An exchange living donor program for liver transplantation, similar to the exchange living donor kidney program, was proposed to avoid ABO-incompatible adult living donor liver transplantation (LDLT). The objective of this study was to present updated changes in exchange adult LDLT program at our institution.Methods. Between January 2003 and December 2011, approximately 2,182 adult LDLT cases were included in this study. During this period, 26 paired-exchange donor LDLT cases were performed (1.2%).Results. Of the 26 paired-exchange donor LDLT cases, 22 pairs were matched due to ABO-incompatibility, and 4 pairs were matched because of cascade allocation of unrelated donors or relatively small graft volume to the recipients. A total of 28 living donors were included in the 26 paired-exchange donor LDLT cases because of inclusion of two dual-graft transplants. Elective surgery was performed in 22 cases, and urgent operation was performed in 4 cases. The overall 1-year and 5-year patient and graft survivals were both 96.2% and 90.1%, respectively. Conclusions. Our experience suggests that the paired-exchange donor program for adult LDLT seems to be a feasible modality to overcome donor ABO incompatibility. Reasonably acceptable indications for donor exchange LDLT will be proposed in near future.
