Effect of the surgical technique on long-term outcome of pancreas transplantation

To date there is no general consensus as to the best surgical technique for pancreas transplantation. Patients with a pancreas transplant functioning for 3 years or more were retrospectively investigated to compare three surgical techniques: segmental graft with duct obstruction (DO), whole graft with bladder drainage (BD), and whole graft with enteric drainage (ED). Several parameters were studied: patient and graft survival, rejection, long-term surgical and medical complications, and endocrine function. The best results in terms of graft survival and quality of metabolic control were obtained in the group that underwent whole graft transplantation with ED. At 3 years, overall pancreas graft survival was 65% for ED, 60% for BD, and 47% for DO. This surgical method has become the preferred technique in our unit.
