Objective: To report initial experience with the combination of a novel technique of portal-enteric pancreas transplantation with newer immunosuppressive strategies that eliminate antilymphocyte induction therapy. Background A new surgical technique of pancreas transplantation has been developed with portal venous delivery of insulin and enteric drainage of the exocrine secretions (portal-enteric). The introduction of potent immunosuppressive agents may allow simultaneous kidney and pancreas transplants (SKPT) to be performed without antilymphocyte induction. Methods: From September 1996 to November 1998, the authors performed 28 primary SKPTs with portal-enteric drainage and no antilymphocyte induction. All patients received triple immunosuppression with tacrolimus, mycophenolate mofetil, and steroids. The study group had a mean age of 38 years and a mean preoperative duration of diabetes of 25 years. Four patients (14%) had prior kidney transplants. Results: All patients had immediate renal allograft function. Actual patient, kidney, and pancreas graft survival rates were 86%, 82%, and 82%, respectively, after a mean follow-up of 12 months. Four patients died, three as a result of cardiac events unrelated to SKPT. Five kidney and five pancreas grafts were lost; including five deaths with function and three cases of chronic rejection. The mean length of stay and total charges for the initial hospital stay were 12.5 days and $99,517. The mean number of readmissions was 2.9, and 10 patients (36%) had no readmissions. Six patients (21%) developed acute rejection, with five (18%) receiving antilymphocyte therapy. Seven patients (25%) underwent relaparotomy, including two (7%) for intraabdominal infection. Nine patients (32%) had major infections, including three (11%) with cytomegaloviral infection. Of the 24 surviving patients, 22 (92%) are both dialysis- and insulin-free. Conclusion: These preliminary results suggest that SKPT with portal-enteric drainage without antilymphocyte induction can be performed with excellent outcomes.
