PURPOSE:To compare the efficacy of different types of solutions (Belzer or Euro-Collins) for the preservation of rat pancreas during cold ischemia. METHODS:Thirty Wistar rats were divided into three groups according to the perfusion or storage solution: Group E (perfusion and storage in Euro-Collins solution); Group B (perfusion and storage in Belzer solution) and Group BE (Perfusion in Belzer solution and storage in Euro-Collins solution). After perfusion, the pancreas was excised and stored at 4˚C for 18 hours. Amylase was measured at 6, 12 and 18h, and histological analysis of the pancreas was performed after 18h of cold storage.RESULTS:Amylase was elevated and comparable in Groups E and BE after 12 and 18 hours of ischemia (p<0.05). In the exocrine pancreas, histological differences in the amount of necrosis (p=0.049), lymphocytic infiltrate (p<0.001) and neutrophilic infiltrate (p=0.004) were observed, with more favorable features present in Group B. In the endocrine pancreas, Group B showed less edema (p<0.001), but other parameters were similar among all groups. CONCLUSION:The Euro-Collins solution is inferior to the Belzer solution for the preservation of rat pancreas during cold ischemia.
