title: Histopathological Examination may be Useful for Assessment of Fibrosis and Lipomatosis of Pancreas Allograft Prior to Solid Organ Transplantation.
abstract: BACKGROUND
  The results of pancreas transplantation depend in a large degree on appropriate pancreas allograft donor selection. Several risk factors of early surgical complications or pancreas allograft loss following transplantation have been identified, but the final decision on pancreas harvesting for transplantation belongs to the surgeon. In the present study we aimed to assess whether histopathological examination may be utilized for detection of fibrosis and lipomatosis in tissue from a potential pancreas allograft. Additionally, we aimed to test whether presence of pancreatic fibrosis and lipomatosis may be explained solely by donor age and/or body mass index (BMI).
  
  
  METHODS
  Pancreata retrieved from 50 deceased organ donors referred to our institution and not transplanted between 2010 and 2013 were used for the present study. Tissue samples were excised from pancreata, fixed in formalin, and embedded in paraffin. Presence and intensity of pancreatic fibrosis and lipomatosis were assessed semi-quantitatively.
  
  
  RESULTS
  Fibrosis was found in the majority of study samples (72%), but it was usually mild or moderate. Lipomatosis was present in 34% of the study cases. Presence of fibrosis was more frequent in older donors, but was still not rare in donors under 40 years old. Presence of lipomatosis did not seem to be significantly related to donor age. Neither pancreatic fibrosis nor lipomatosis was related to donor BMI.
  
  
  CONCLUSIONS
  There is no clear relationship between histological parenchymal changes in potential pancreas allograft and donor age and BMI. Histopathological assessment of pancreatic fibrosis and/or lipomatosis can potentially facilitate decision making on pancreas allograft acceptance for solid organ transplantation.
