title: Pancreatic and islet autotransplantation.
abstract: The techniques of segmental pancreatic autotransplantation and intraportal islet autografting have been reported to prevent diabetes after resection of the diseased pancreas. Unless total pancreatectomy is done, transplant function cannot be assessed without measuring insulin in the venous effluent. Islet infusion appears to be a more uncertain technique than segmental autotransplantation, probably because of technical difficulties in obtaining sufficient islets. Both methods have serious potential for morbidity and mortality, which must be balanced against the possible benefits of improved glucose homeostasis. In segmental autografts we recommend an intraperitoneal transplant site with iliac vessel anastomosis, and a lateral pancreaticojejunostomy to provide ductal drainage. For islet transplantation we recommend extreme caution and the use of only very pure islet preparations for portal vein infusions. There is insufficient long-term follow-up of patients with successful auto- or allotransplants to be certain that secondary complications of diabetes will be less than those of patients on insulin therapy. Further experience is necessary before the long-term functional survival of segmental or islet autografts will be known.
