[Pancreas and islet transplantation]

Pancreas transplantation is a successful and effective procedure resulting in tight glucose control. Due to the postoperative morbidity and the need for immunosuppression pancreas transplantation should be considered in patients with type I diabetes at the time of kidney transplantation. Besides this pancreas transplantation alone can be taken into consideration for patients with very poor metabolic control and quality of life despite optimal medical treatment. Recently, islet transplantation became a less invasive alternative to pancreas transplantation. Due to the lack of long-term follow-up and due to the need of multiple donor grafts for one recipient, islet transplantation should be performed under experimental settings in experienced centers. New developments in protecting transplanted islets and in the induction of donor-specific tolerance could increase the indication to perform the procedure. Therefore alternative sources of beta-cells have to be identified.
