Pancreas graft quality directly affects morbidity and mortality rates after pancreas transplantation (PTx). The criteria for pancreas graft allocation are restricted, which has decreased the number of available organs. Suitable pancreatic allografts are selected based on donor demographics, medical history, and the transplant surgeon's assessment of organ quality during procurement. Quality is assessed based on macroscopic appearance, which is biased by individual experience and personal skills. Therefore, the aim of this study is to assess the histopathological quality of unallocated pancreas organs to determine how many unallocated organs are of suitable quality for PTx, based on histopathologic evaluations. The reasons for allocation rejection will be reported and the correlation between cause of allocation rejection and histopathological quality of the allocated organ will be evaluated. This is a multicenter cross-sectional explorative study. The demographic data and medical history of donor and cause of rejection of the allocation of graft will be recorded. Organs of included donors will be explanted and macroscopic features such as weight, color, size, and stiffness will be recorded. A tissue sample of the organ will be fixed for further microscopic assessments. Histopathologic assessments will be reported 6 hours (or at time of organ delivery if later than 6 hours), 9 hours, 12 hours, 15 hours, and 18 hours after procurement. 100 pancreases will be evaluated in this study.
