Salvage Islet Auto Transplantation After Relaparatomy.

Background: To assess feasibility, safety and metabolic outcome of islet auto transplantation (IAT) in patients undergoing completion pancreatectomy because of sepsis or bleeding following pancreatic surgery. Methods: From November 2008 to October 2016, 22 patients were candidates to salvage IAT during emergency relaparotomy because of postpancreatectomy sepsis (n=11) or bleeding (n=11). Feasibility, efficacy, and safety of salvage IAT were compared to those documented in a cohort of 36 patients who were candidate to simultaneous IAT during nonemergency preemptive completion pancreatectomy through the pancreaticoduodenectomy. Results: The percentage of candidates that received the infusion of islets was significantly lower in salvage IAT than simultaneous IAT (59.1% vs 88.9%; p=0.008), mainly due to a higher rate of inadequate islet preparations. Even if microbial contamination of islet preparation was significantly higher in candidates to salvage IAT than in those to simultaneous IAT (78.9% vs 20%, p
