Surgical Tips and Tricks for Performing Porcine Pancreas Transplantation

Despite the promising results of pancreas transplantation in type 1 diabetes mellitus and metabolic syndrome, the biggest concern around this state-of-the-art technique remains the paucity of organs deemed fit for transplantation. High intravascular resistance, delicate intraparenchymal capillary framework, and complex lobular anatomy around the mesenteric vasculature are what make this organ more susceptible to injury and less tolerant to trivial trauma compared to organs such as the liver and kidney. Meticulous surgical dissection and judicious tissue handling form the cornerstone of the entire exercise of pancreas transplantation. Owing to morphological similarity between the anatomy of the porcine pancreas to the surrounding mesenteric vessels and the organs when compared to the human anatomy, demonstration of the technique in the porcine model could help to most accurately extrapolate this to a human setting. The present article aims to outline the essential surgical tips and tricks that need to be followed, in order to ensure a higher success rate of transplantation of this highly susceptible organ in a porcine 3-day survival model.
