Pancreas Transplantation and Outcomes Management

Pancreas transplantation represents a definitive surgical intervention for selected patients with insulin‐dependent diabetes and, in many cases, concurrent renal failure. The principal approaches include pancreas transplant alone (PTA), simultaneous pancreas–kidney transplantation (SPK) and combinations involving living or deceased donor kidneys (such as SPLK). Outcomes management encompasses donor selection, organ preservation, surgical technique, perioperative care and long‐term surveillance of graft function. Immunological challenges—chiefly acute and chronic rejection mediated by cellular and antibody pathways—remain a leading cause of graft loss. Early postoperative complications such as graft thrombosis and thromboinflammatory activation require prompt recognition through imaging and biomarker monitoring. Over the longer term, maintenance of normoglycaemia reduces microvascular and macrovascular complications, improving patient survival and quality of life. Advances in surgical approaches, immunosuppressive regimens and organ‐allocation strategies are expanding access, while integrated outcome registries and patient‐reported measures are refining selection criteria and aftercare protocols on a global scale.

Research from Nature Portfolio

Recent studies have compared outcomes between conventional SPK and split donor models combining deceased‐donor pancreas with living‐donor kidney grafts. Analysis of cohorts undergoing SPK versus SPLK revealed comparable patient survival but identified a higher incidence of biopsy‐proven acute rejection and reduced pancreas graft survival in the SPLK group, underscoring the need to optimise immunosuppression and donor matching in alternative allocation schemes. In addition, large‐scale registry analyses over extended follow‐up have demonstrated that donor–recipient sex mismatch constitutes an independent risk factor for pancreatic graft failure. These findings suggest that sex pairing should be considered alongside established donor and recipient characteristics to improve allocation algorithms and graft longevity.

Technical terms

Simultaneous pancreas–kidney transplantation (SPK): Combined grafting of a pancreatic and renal allograft in a single operative session to treat diabetes with end‐stage renal disease.

Pancreas transplant alone (PTA): Transplantation of a pancreatic graft without concurrent kidney transplantation, typically reserved for brittle diabetes without renal failure.

Donor–recipient sex mismatch: A transplant scenario in which donor and recipient are of opposite biological sex, shown to influence graft survival through immunological and hormonal factors.

Thromboinflammatory response: The interplay of coagulation and innate immune activation that can precipitate early vascular thrombosis and graft loss.

Graft survival rate: The proportion of transplanted organs that remain functional over a defined follow‐up period, serving as a key metric of transplant success.
