The improved results with pancreas transplantation in general, and the emerging evidence that the procedure favorably influences the course of secondary diabetic complications, given an impetus to retransplant patients whose initial graft has failed. In order to determine whether a pancreas retransplant policy is justified, we analyzed the results at our own institution. From 1978 through 1989, 327 pancreas transplants were performed in 261 patients, including 259 primary (79%) and 68 retransplants (21%) after a previous one failed (including 2 primary transplants performed elsewhere), with 48 second (15%), 18 third (5%), and 2 fourth (1%) transplants. The surgical techniques used in the 261 primary PxTxs were open-duct free drainage into the peritoneal cavity in 15 recipients, of whom 3 (20%) were retransplanted: duct occlusion in 34, of whom 9 (26%) were retransplanted intestinal drainage in 78, of whom 23 (29%) were retransplanted; and bladder drainage in 134, of whom 13 (10%) were retransplanted. The surgical techniques used for the 68 pancreas retransplants were duct occlusion in 11 (10 second, 1 third), intestinal drainage in 12 (9 second, 3 third), and bladder drainage in 45 (29 second, 14 third, and 2 forth); bladder drainage has been used nearly exclusively for the most recent pancreas retransplants. The recipient categories in the 261 primary transplants were pancreas alone in 115, of whom 29 (25%) were retransplanted, pancreas after kidney in 81, of whom 17 (21%) were retransplanted, and simultaneous pancreas and kidney transplants in 63, of whom 2 (3%) were retransplanted. Of the 68 pancreas retransplants, 32 (47%) were pancreas alone (26 second, 6 third), 24 (35%) were pancreas after kidney (17 second, 6 third, 1 fourth), and 12 (18%) were simultaneous pancreas and kidney (5 second, 6 third, 1 fourth). Overall patient survival rates were similar (P = 0.48), at 1 month (actual [98% after primary and 94% after retransplantation]) and at 1 year (actuarial [91% vs. 89%]). Overall graft functional rates were also similar, at 1 month (actual [76% for all primary and 79% for all retransplants - P = 0.9]), and at 1 year (actuarial [46% vs. 43% - P = 0.9]). Causes of graft losses at 1 months were similar for primary (18% were technical failures, 6% were rejected) and retransplant (16% were technical failures, 3% were rejected) cases.(ABSTRACT TRUNCATED AT 400 WORDS)
