title: Long-term results after pancreas transplantation.
abstract: With the advances in technique and immunosupression, not only the short- but the long-term outcomes of pancreas transplantation have improved significantly. This retrospective study describes the long-term outcomes of simultaneous pancreas and kidney (SPK) transplants, pancreas after kidney (PAK), and pancreas transplants alone (PTA). An overall analysis was performed for all deceased donor (DD) primary pancreas transplants performed in the United States between 1988 and 1999. In addition, the long-term outcome for pancreas transplants performed at the University of Minnesota (UM) was analyzed. For SPK transplants performed in the United States between 1998 and 1999, the half-life of the pancreas was almost 12 years, and was 12.5 years for kidneys. For SPK cases where the pancreas was functioning at 1 year, the half-lives of both the pancreas and the kidney grafts extended more than 14 years. The half-lives of solitary pancreas transplants were between 7 years for PAK and 9 years for PTA cases. For US solitary transplants with at least 1 year of graft function, the half-lives extended to almost 9 years. Pancreas transplants performed at the UM showed the same significant improvements over time. Of special interest is the excellent long-term graft function of pancreas transplants from a living donor, which in the early years clearly surpassed that of solitary DD pancreas transplants. A multivariate analysis showed that the factor with the highest impact on long-term graft function in all three transplant categories was the use of a young donor. In SPK cases, the most frequent reason for late graft loss was death with a functioning graft. In solitary pancreas transplants, most late graft losses were still due to immunological reasons.
