Summary:

The aims: to compare the state of carbohydrate metabolism in animals after pancreatectomy with autotransplantation of the pancreatic segment and with organization of the venous outflow in the inferior vena or portal vein. Material and methods. Proximal resection of the pancreas (group 1), pancreatectomy with autologous transplantation of the pancreas and with reconstruction of the venous outflow from the transplant into the inferior vena cava (group 2) and pancreatectomy with autologous transplantation of the pancreas and with reconstruction of the venous outflow from the transplant into the portal vein (group 3) were performed in 45 animals in the experiment. Examining the status of carbohydrate metabolism was performed by intravenous test for glucose tolerance. Results. Primary higher increase in glucose concentrations as compared to the values obtained at the intact animals and its slower decrease have been observed in animals after pancreatectomy with autotransplantation of the segment of the pancreas on iliac vessels (group 2), as well as on the mesenteric vessels (group 3). Higher blood glucose compared to animals subjected proximal pancreatectomy after 40 minutes after administration of glucose was detected in animals undergoing autotransplantation of the pancreas on iliac vessels (group 2) and in animals after autotransplantation of the pancreas on mesenteric vessels (group 3)— 11.82 (11,39-12,26) mmol/l and 10.65 (10,03-11,32) mmol/l, respectively. The glucose concentration in the blood plasma was lower in the animals of groups 2 and 3 below in comparison with the animals in group 1 to 120 minutes of the experiment. Significant differences in plasma glucose concentration between animals of groups 2 and 3 were not found. Conclusion. Significant effects of the ways of organization of the venous outflow from pancreatic transplant on the concentration of the glucose in the blood plasma by the carbohydrate load after pancreatectomy with autotransplantation of the pancreas were not found.
