Can low volume liver transplant centers be successful? The Regional Transplant Center of Willis-Knighton & Louisiana State University Medical Center. The first 120 liver transplants.
The development of orthotopic liver transplantation represents this century's most significant advance in the management of liver disease. In the 1980s the vast majority of liver transplants were performed at several large centers; however, in this decade, improvements in techniques and success rates have allowed live transplantation to expand to regional centers across the country, particularly in the southeast. This proliferation of regional centers and the widening disparity between organ availability and numbers of recipients have created tremendous controversy at the national level regarding the allocation scheme used to distribute livers to recipients. The large programs today are advocating change to a national waiting list which would eliminate local priority and jeopardize the existence of smaller regional centers. Furthermore, the large programs favor establishing a limited number of megacenters where all liver transplants would take place, arguing that low volume centers cannot perform liver transplants with acceptable complication and survival rates. At the Regional Transplant Center of Willis-Knighton Hospital and Louisiana State University Medical Center in Shreveport (WK/LSUMC) we performed 122 liver transplants between July 1, 1991 and December 31, 1997. The purpose of this study was to examine our complication and survival rates and compare them to national averages. The actuarial graft survival at 1, 2, and 3 years in this series compared to the national average respectively was 76% and 70%, 66% and 66%, 62% and 62%. The actuarial patient survival (WK/LSUMC vs National) at 1, 2, and 3 years was 80% and 80%, 75% and 75%, 70% and 74%. The rate of retransplantation was 8% with a national average of 10% to 20%. Our rate of graft primary non-function was 5% with the national average being 2% to 10%. The rate of vascular thrombosis of the graft in this series was 2% with a national rate of 5%. The differences in these results were not statistically significant (P < .05). Low volume transplant centers can perform liver transplant successfully, allowing the regionalization of the treatment of choice for end-stage liver disease.
