Segmental pancreas transplantation from living related and cadaver donors: a clinical experience.

: Between July 25, 1978, and January 25, 1981, 20 segmental pancreas transplants from 14 cadaver (cad) and six related (rel) donors were performed. All but two recipients had previously received renal allografts for treatment of end-sage diabetic nephropathy. The grafts were placed intraperitoneally-13 with open ducts, 4 with prolamine-injected ducts, and 3 with silicone rubber-injected ducts. At this writing six patients have functioning grafts (3 silicone, 3 open duct) at less than 1 (cad), 2 (cad), 3 (rel), 15 (cad), 20 (rel), and 31 (cad) months. Five open-duct grafts failed for technical reasons. Two prolamine-injected grafts lost function between 1 and 3 months; biopsy specimens showed severe fibrosis. The others lost function between 2 and 4 months. Three patients died 1 to 3 months after transplantation. Metabolic test results were normal or nearly normal in most recipients with functioning grafts. Splenectomy was required in one related donor; there were no other complications of donation. Technical problems and rejection are impediments to application of pancreas transplantation, but a sustained correction of the metabolic defect has been achieved in a few patients, and the effect on secondary complications are studied.
