Between July 1978 and February 1987, 177 pancreas transplants were performed. The 1-year patient and graft survival rates for the first 100 transplants up to October 1984 were 88% and 27%, respectively. Since November 1984, duct drainage has been used for 74 of 77 transplants, bladder (BD) in 36 and enteric (ED) in 38, with 1-year patient survival rates of 89% and 92%, respectively, and graft survival rates of 58% and 42%. The technical failure rate was similar in both groups (31%). Immunosuppression was with antilymphocyte globulin, cyclosporine, azathioprine, and prednisone. Most recipients were nonuremic, without kidney transplants, and 1-year graft survival rates were 69% for BD (n = 21) and 42% for ED (n = 29). The diagnosis of rejection was based on a decline in urine amylase activity in the BD and on an increase in plasma glucose alone in the ED group. For technically successful (TS) grafts, the number of rejection episodes reversed per number diagnosed was 23 of 26 (18 patients) in BD (88%) and six of 15 (14 patients) (40%) in ED (p < 0.05). The advantage of BD with monitoring of urine amylase activity is seen in TS cases; 1-year cadaveric graft survival rates were 90% for BD (n = 23) versus 47% for ED (n = 15) (p = 0.05). In recipients of segmental transplants with ED from living-related donors, 1-year graft survival rates were 57% overall (n = 18) and 88% for TS cases (n = 12), which is identical to cadaveric BD cases. A disadvantage of BD was metabolic acidosis induced by chronic bicarbonate loss in the urine from the pancreas graft. Nevertheless, we conclude that BD is the preferred technique for pancreas transplants from cadaver donors because of the ability to monitor exocrine and endocrine function continuously, thus leading to early diagnosis and treatment of rejection episodes.
