Abstract
We have studied differences in reperfusion between the pancreas and the duodenum after 6 hr of cold storage in a porcine whole-organ pancreaticoduodenal allograft transplantation model. Two different flush-out and storage solutions, Perfadex and EuroCollins, were compared. Graft duodenal mucosal pH (pHi) was measured as an indicator of duodenal mucosal reperfusion. Pancreatic reperfusion was estimated indirectly using a ratio between the release of immunoreactive cationic trypsin (irCT) to serum 10 and 60 min following reperfusion. Twelve pigs (Perfadex n = 6, EuroCollins n = 6) were transplanted and all showed preserved endocrine and exocrine function postoperatively. Our data support the concept that reperfusion of a pancreaticoduodenal graft can be estimated using duodenal pHi and that the ratio of irCT at 10 and 60 min gives an indirect estimate of pancreatic reperfusion. The results also show that grafts stored in EuroCollins reperfuse more slowly than grafts stored in Perfadex.
