| Outline of Final Research Achievements |
To evaluate pancreas volumetric function (PVF) of the graft and live donor residual pancreas using 11C-methionine PET/CT in pancreas transplantation. Pre- and post-operative pancreas volume in donor was 29.3±7.5 and 38.0±7.9ml. Pre- and post-operative SUV in donor was 16.0±1.1and 16.9±5.0. PVF was elevated 1.38-times postoperatively. Assuming that the normal PVF is 100%, pre- and post-operative PVF in donor was 113% and 57%. Insulin independent PVF with brain-death and live donor was 70% and 24%. Insulin dependent PVF and graft failure was 12% and 0%.Pancreas regeneration was observed volumetric 38%, but functional 6% in donor pancreas.
