Prolonged preservation increases surgical complications after pancreas transplants

Prolonged preservation of the donor organ may result in delayed graft function or nonfunction after most organ transplants. We studied whether or not prolonged preservation increases surgical complications after pancreas transplants.

Between January 1, 1994, and September 30, 1998, a total of 294 recipients underwent cadaver pancreas transplants at our institution. Recipients were analyzed in 2 groups: those with pancreas preservation time < or = 20 hours (n = 211) versus > 20 hours (n = 83).

Demographic data were similar between the 2 groups, except that mean donor age in the prolonged preservation group was significantly lower. Despite use of younger donors, prolonged preservation was associated with an increased incidence of surgical complications, most notably leaks, thrombosis, and wound infections. Grafts with prolonged preservation were more often noted by the transplant surgeon to be edematous after reperfusion, although the incidence of hyperamylasemia posttransplant did not differ between the 2 groups. Graft and patient survival rates also did not differ between the 2 groups. The incidence of early graft loss (< 3 months) was, however, higher in the prolonged preservation group (20.5% versus 9.0%, P = .04).

Prolonged preservation of the donor organ increases the incidence of surgical complications after pancreas transplants. All attempts should be made to minimize preservation time, keeping it below 20 hours, if possible.
