Current status of pancreas transplantation.

Pancreas transplantation for the treatment of diabetes mellitus is being done with increasing frequency. Refined operative techniques, an improved immunosuppression regimen, and an earlier recognition of rejection have led to dramatic increases in both graft and patient survival rates. Preliminary data suggest that a functioning pancreatic allograft may arrest or reverse most of the complications of diabetes, although the effects on retinopathy remain controversial. Patients also acquire a strong sense of well-being after successful pancreas transplantation.
