Introduction

Pancreatic transplantation stands at the forefront of innovative medical interventions for individuals grappling with the complexities of end-stage diabetes mellitus. As the prevalence of diabetes continues to rise globally, the demand for effective and sustainable treatment options becomes ever more pressing. Among the array of therapeutic avenues, pancreatic transplantation holds the promise of not merely managing but potentially curing diabetes, offering recipients a renewed lease on life [1-3]. This comprehensive review aims to navigate the landscape of recent advancements in pancreatic transplantation, providing a synthesis of breakthroughs in surgical techniques, immunosuppressive strategies, and emerging technologies. By delving into the intricacies of simultaneous pancreas-kidney (SPK) and solitary pancreas transplantation, we unravel the nuanced benefits and challenges inherent in each approach [4,5]. The immunological aspects of pancreatic transplantation form a cornerstone of this exploration. The review scrutinizes the evolution of immunosuppressive protocols, emphasizing the delicate balance between preventing rejection and minimizing adverse effects. In an era where precision medicine tailors interventions to individual patient profiles, we investigate the potential for personalized immunosuppression to enhance graft survival and long-term patient outcomes. As an alternative to whole organ transplantation, islet transplantation has garnered significant attention [6-8]. The paper elucidates recent advancements in islet isolation techniques, encapsulation technologies, and the application of biomaterials to create a conducive microenvironment for islet engraftment. The burgeoning field of stem cell-based therapies is also examined as a futuristic avenue, offering potential solutions to the persistent challenge of donor organ shortages. Beyond the technical aspects, this review contemplates the economic and ethical dimensions of pancreatic transplantation [9]. A critical analysis of the costeffectiveness of transplantation compared to conventional diabetes management is presented, alongside an exploration of the ethical considerations inherent in organ allocation and donor procurement processes. In a paradigm where technology converges with medicine, artificial intelligence (AI) and machine learning have emerged as powerful tools. This review evaluates the current state and future prospects of AI applications in predicting graft outcomes, optimizing patient selection, and revolutionizing post-transplant monitoring [10]. As we embark on this comprehensive journey through the advancements in pancreatic transplantation, the synthesis of multidisciplinary research endeavors aims to contribute to the evolving landscape of transplantation science. By consolidating knowledge from surgery, immunology, bioengineering, and data science, this review endeavors to serve as a compass guiding future research and innovations in the dynamic field of pancreatic transplantation.
