[Metabolic sequelae of pancreatic transplantation using two different surgical techniques].
BACKGROUND
By transplantation of the pancreas in diabetics type 1 long-term-term independence on exogenous insulin can be achieved. The extent of normalization of the carbohydrate metabolism can depend on the applied surgical technique. The objective of the submitted work was to compare indicators of compensation of diabetes one year after combined transplantation of the kidney and pancreas, using the method of transplantation of a segment of the pancreas with obliteration of the pancreatic duct by a polymer and the method of transplantation of the whole pancreas with drainage of the pancreatic duct into the urinary bladder.


RESULTS
The authors examined two groups of recipients, 13 subjects each with full function of the pancreatic graft one year after transplantation where a combined transplantation of the kidney and pancreatic segment (group SP) had been performed or of the kidney and whole pancreas (group CP). The authors investigated the blood sugar level, glycated haemoglobin, intravenous glucose tolerance test, free insulin level and C-peptide as well as some indicators of the lipid metabolism and acid base balance. In both groups normal blood sugar levels were achieved, though the mean values in the course of the day were higher in group SP than in group CP (mean +/- SE 5.48 +/- 0.11 as compared with 4.98 +/- 0.09; p < 0.01). Glycated haemoglobin declined in group SP from the pretransplantation value of 9.31 +/- 0.09 to 6.40 +/- 0.10% and in group CP from 9.49 +/- 0.15 to 4.92 +/- 0.08%. In group CP the glycated haemoglobin after transplantation was significantly lower (p < 0.01), similarly as the coefficient of glucose assimilation (1.83 +/- 0.03 as compared with 1.25 +/- 0.15; p < 0.05). Indicators of the acid base balance did not differ. Recipients in group CP were however permanently treated with bicarbonate.


CONCLUSIONS
With both transplantation method it is possible to achieve compensation of diabetes close to normal. The carbohydrate tolerance is however better after transplantation of the whole pancreas.
