[Pancreas transplantation in dogs, effect on the endocrine pancreas of pancreatic duct obliteration and the mode of pancreas preservation. Histological study by surface analysis in dogs].
The effects of organ preservation and of canal obliteration on the endocrine pancreas were investigated in three groups of dogs. A control group of 6 animals were used for the histological examination of the normal pancreas. Two randomized groups (A and B) of 7 dogs the caudal pancreas was autotransplanted; a fibrin glue was injected into the pancreas canals 28 days before organ removal. In the group A, each graft was rinsed in a Euro-Collins solution and immediately transplanted. In group B, each graft was rinsed and held in a preservation solution for 24 hours before transplantation. On histological slices the ratio between of the total surface area of Langerhans islets to the mean surface area of each islet was greater in the control group than in group A (p = 0.011 and 0.023); the ratio was not significantly different between the control group and the group B (p = 0.334 and 0.099). The histological surface area study suggested that the mode of organ preservation affects the endocrine pancreas and that blocking the canals has little effect.
