Outcomes of extended donors in pancreatic transplantation with portal-enteric drainage

Objective. Limited data are available on extended (EX) donor criteria in pancreatic transplantation (PTX). Methods. This retrospective study from February 2007 through April 2007 compared 2 cohorts of simultaneous kidney-pancreas transplantations (SKPT): the first from EX donors, which were defined as age <10 years or >= 45 years, or donation after cardiac death [DCD]), and the second from conventional (CONV) donors. Results. Among 79 SKPT, 19 (24%) were from EX donors (12 older than age 45 [mean age, 50.2 years], 3 pediatric donors <10, and 4 DCD donors) and the remaining 60 SKPT from CONV donors. The mean donor age was higher in EX than CONV donors (38 vs 25 years, P < .05). There were no other differences between the 2 cohorts. With a similar median follow-up of 29 months, patient, kidney and pancreatic graft survival rates were 89%, 89%, and 79%, for the EX, whereas corresponding outcomes for CONV donors were 93%. 87%, and 80%, respectively (all P = NS). The incidences were similar for delayed kidney graft function (5% in each group), early pancreatic graft loss due to thrombosis (5% EX vs 8% CONV donors), acute rejection (16% EX vs 18% CONV donors), surgical complications, and infections. There were no significant differences in 1-year mean serum creatinine (1.4 mg/dL in each group) or glycohemoglobin (5.2% vs 5.5%) levels between the EX and CONV donor groups, respectively. Conclusion. Short-term outcomes among SKPT from selected EX donors were comparable to CONV donors. Donors at the extremes of age and DCD donors may represent underused resources in SKPT.
