Experience with pancreatic transplantation in Stockholm.

Eight attempts at segmental pancreatic transplantation were made in 6 diabetic patients. While the indications for transplantation differed all the patients were severely incapacitated by the disease. None was uremic. The body and tail of the pancreas from cadaveric donors was used, the grafts were revascularized to the recipient's iliac vessles. Six of the grafts provided control of blood glucose for 7-51 days. Five of the grafts then failed owing to rejection, and one had to be removed while still functioning, because of arterial bleeding. Important lessons have been learned concerning both surgical and immunological aspects of this form of treatment : 1) Ducto-jejunostomy should be used to provide exocrine pancreatic drainage. 2) HLA-DR typing for donor-recipient selection and thoracic-duct drainage as an adjunctive immunosuppressive measure should be used to reduce the incidence of graft rejection. 3) An elevation of the postprandial blood glucose concentration is a first sign of rejection and should cause treatment. 4) Graft rejection can be reversed by conventional steroid medication.
