In the early steps, careful retrieval and preservation of the pancreas arecrucial for the viability of the organ and ultimate success of the transplant. Thepancreas is a low-flow gland, making it highly sensitive to transplantationconditions and presenting risk of pancreatitis due to periods of ischemia. The twogroups of donors - after brain death (DBD) or after cardiac arrest (DCD) - requiredifferent strategies of retrieval and preservation to avoid or reduce the risk ofcomplications developing during and after the transplantation.

Asystole donor (DCD) transplantation, in contrast, can benefit from thenewest technologies, such as hypothermic and especially normothermicpreservation machines (referred to as NECMO), to optimize organ preservation.The latter has led to an increase in the pool of donors by facilitating recuperationof organs for transplantation that would have been discarded otherwise.展开更多
