Deceased after cardiac death donors represent an important source of organs to reduce organ shortage in transplantation. However, these organs are subjected to more ischaemia-reperfusion injury (IRI). Reducing IRI by targeting coagulation is studied here in an experimental model. ⋯ Peritransplant anticoagulation therapy was beneficial to graft outcome, in both the acute and chronic phases. Moreover, specific inhibition of coagulation Xa protease further protected kidney grafts, with better recovery and decreased expression of chronic lesion markers. Surgical relevance The increasing use of marginal donors highlights the importance of organ quality in transplantation. Renal ischaemia-reperfusion injury (IRI), which includes a deleterious activation of coagulation, plays a central role in determining graft quality and outcome. Using an established porcine renal autotransplantation preclinical model with high clinical relevance, the benefits of anticoagulation therapy using an antifactor Xa molecule were evaluated. Peritransplantion anticoagulation treatment, specifically with an anti-Xa compound, protected marginal kidney grafts, improving functional recovery and reducing chronic lesions. This study demonstrates the benefits of anticoagulation therapy at the time of organ collection, particularly for marginal organs, encountered in cases of extended criteria and deceased after circulatory death donors. This anticoagulation strategy could be an important addition to current donor and organ management protocols in order to limit IRI and improve outcome.

Review Meta Analysis Comparative Study
Systematic review and meta-analysis comparing three techniques for pancreatic remnant closure following distal pancreatectomy.
Established closure techniques for the pancreatic remnant after distal pancreatectomy include stapler, suture and anastomotic closure. However, controversy remains regarding the ideal technique; therefore, the aim of this study was to compare closure techniques and risk of postoperative pancreatic fistula (POPF). ⋯ The use of stapler closure or anastomotic closure for the pancreatic remnant after distal pancreatectomy significantly reduces POPF rates compared with suture closure. The combination of stapler and suture closure shows superiority over suture closure alone.
