title: Influence of preservation time on outcome and metabolic function of bladder-drained pancreas transplants.
abstract: The influence of cold storage preservation time on graft survival and metabolic function of pancreatic transplants was studied in 130 recipients of bladder-drained grafts (47 simultaneous with, 33 after, and 50 without a kidney transplant) between October 1, 1984 and May 1, 1989. The recipients were divided into four groups according to the preservation time: less than 6 hr (n = 11), 6-12 hr (n = 24), 12-24 hr (n = 75), and greater than 24 hr (n = 20). Twenty-six grafts were procured by other transplant teams and sent to us. Silica gel fractionated plasma was used for preservation in 104 cases and the University of Wisconsin solution in 25 (1 in the less than 6 hr, 2 in the 6-12 hr, 16 in the 12-24 hr, and 6 in the greater than 24 hr groups). The technical failure rate at 1 month was 13% (17 grafts), 1 (9%) in the less than 6 hr, 5 (21%) in the 6-12 hr, 9 (12%) in the 12-24 hr, and 2 (10%) in the greater than 24 hr groups. At 1 month, 107 (82%) of the grafts were functioning, 10 (91%) in the less than 6 hr, 18 (75%) in the 6-12 hr, 62 (83%) in the 12-24 hr and 17 (85%) in the greater than 24 hr groups, the longest preserved for 30 hr. The respective 1-year graft survival rates were 51%, 50%, 57%, and 70%. Ninety patients (10 in the less than 6 hr, 16 in the 6-12 hr, 51 in the 12-24 hr, and 13 in the greater than 24 hr groups) had metabolic studies between 2 and 6 weeks postransplant. The results of 24-hour profiles (14 blood glucose determinations) were similar in each preservation time group; the means of the mean (+/- SD) profile glucose (mg/dl) values were 130 +/- 19, 126 +/- 31, 130 +/- 24, and 129 +/- 30, respectively (P greater than 0.6). Mean plasma glucose levels at 2 hr during OGTT were 141 +/- 32, 145 +/- 43. 163 +/- 49, and 184 +/- 100 in the respective preservation groups (P greater than or equal to 0.064). According to the National Diabetes Data Group classification, 75% of recipients in the less than 6 hr, 50% in the 6-12 hr, 44% in the 12-24 hr, and 33% in the greater than 24 hr groups had normal OGTT results.(ABSTRACT TRUNCATED AT 400 WORDS)
