Pancreas transplant alone.

Pancreas transplant alone (PTA) represents a growing proportion of overall pancreas transplantations, with 1-year patient and graft survivals of almost 100% and higher than 80%, respectively. PTA can restore normoglycemia without exogenous insulin administration and eliminate acute diabetic complications. In our series of 28 PTA, performed with portal-enteric drainage, 2-year patient and pancreas survivals were 100% and 87%, respectively. In patients with successful transplantation, rapid normalization of blood glucose level and HbA1c concentration was observed, due to restored endogenous insulin secretion. Several classical cardiovascular risk factors were measured before and after transplant, with significant improvements shortly after transplantation. Diabetic retinopathy improved in 58.8% of examined eyes, stabilized in 35.3%, and worsened in 5.9%. In conclusion, PTA represents a clinically relevant option for patients with type 1 diabetes without advanced renal disease. It restores normoglycemia in the vast majority of patients and seems to have a positive impact on late diabetic complications.
