    Abstract:
    BACKGROUND: Most solitary pancreas transplants (SPTx) fail due to unrecognized rejection episodes. Consequently, SPTx are monitored by drainage into the bladder or by surveillance biopsies. METHODS: Between April 2001 and June 2003, a consecutive series of 48 SPTx were performed using portal enteric drainage (PED). Rejection episodes were diagnosed empirically, based on the elevated pancreatic enzymes without a surveillance biopsy. Immunosuppression consisted of basiliximab (n = 42) or ATG (n = 6), low-dose steroids, MMF, and tacrolimus. Donors (mean age 28.9 year; range 9 to 54 year) were selected according to standard criteria irrespective of HLA match, although the best HLA matching was considered at the time of graft allocation. RESULTS: After a mean cold ischemia time of 676 minutes (range 475 to 900 minutes), all but two pancreata (95.8%) functioned immediately. Relaparotomy was required in seven cases (14.6%). Three grafts were lost in the early posttransplant period due to hyperacute rejection. Two additional grafts were lost later due to arterial thrombosis or to chronic rejection. After a median follow-up period of 12.2 months (range 0.2 to 27 months) three further recipients were diagnosed with rejection episodes that were reversed with steroid boluses. Actuarial 1-year patient and graft survival rates were 100% and 93.1% and 2-year figures 100% and 88.7%, respectively. At the longest follow-up no recipient was diagnosed with a malignancy. CONCLUSIONS: With current immunosuppression protocols SPTx achieves high rates of insulin independence even without surveillance biopsy or routine use of T-cell-depleting therapies.
