Background:
Within recent years, more marginal donors have been offered to Eurotransplant. To help identify suitable pancreas donors, the Eurotransplant Pancreas Advisory Committee introduced a donor score system (P-PASS). Little is known about the influence of P-PASS on long-term pancreas graft survival.
Methods:
From June 1994 to September 2009, we performed 405 pancreas transplantations. In a retrospective study we analyzed P-PASS in 318 cases. Pancreas grafts from donors with P-PASS < 17 (n = 146) analyzed for graft and patient survival as well as for surgical complications were compared with donors of a PASS > or = 17 (n = 172). The mean follow-up was 7.2 +/- 4.3 years.
Results:
Recipient characteristics were comparable in both groups. Mean P-PASS was 16.7 +/- 2.7 for both groups: 14.3 +/- 1.5 for P-PASS < 17 and 18.8 +/- 1.6 for P-PASS > or = 17. Pancreas graft survival rates for 1, 5, and 10 years were 85%, 77%, and 73% among P-PASS < 17 and 81%, 73%, and 64% among P-PASS > or = 17 groups (P = .12). There were 12 (8.2%) cases of venous thrombosis in the <17 group and 22 (12.7%) in the > or =17 group (P < .05). The relaparotomy rate was significant higher (38.7% vs 28.7%) and duration of hospital treatment longer (40.2 vs 32 days) in the P-PASS > or = 17 group (P < .05). There was no significant difference in patient or kidney graft survival between groups.
Conclusions:
The data demonstrated that utilization of pancreas grafts from donors with a P-PASS > or = 17 resulted in good overall outcomes and could expand the organ donor pool. There was no correlation between P-PASS and long-term patient or graft outcome. Complications requiring relaparotomy were more frequent among patients after transplantation from donors with higher P-PASS.
