Introduction

Abdominal organ transplantation stands as a beacon of hope in the realm of modern medicine, offering transformative solutions for individuals grappling with end-stage organ failure. This comprehensive overview delves into the recent advancements that have propelled the field forward, encompassing the intricacies of liver, kidney, pancreas, and small intestine transplantation [1-3]. The landscape of abdominal organ transplantation has witnessed remarkable progress, driven by breakthroughs in surgical techniques, organ preservation technologies, and innovative immunosuppressive strategies. As the demand for donor organs continues to outpace supply, the quest for optimizing transplant outcomes has become more urgent than ever. One pivotal aspect of these advancements lies in the evolution of organ preservation methods [4]. Hypothermic machine perfusion and normothermic perfusion have extended the preservation window, enabling medical professionals to salvage and transplant organs that were once deemed unsuitable. These technologies have not only increased the pool of viable organs but also enhanced post-transplant graft function [5,6]. Immunosuppression, a cornerstone of transplantation, has undergone a paradigm shift with the advent of precision medicine and targeted therapies. Researchers and clinicians are now navigating the delicate balance between preventing rejection and minimizing the side effects associated with immunosuppressive regimens. This personalized approach holds the promise of improving long-term graft survival and enhancing the overall quality of life for transplant recipients [7]. Liver transplantation, a field marked by its own set of challenges, has seen groundbreaking developments. Living donor transplantation and the utilization of split liver grafts have addressed the scarcity of donor organs, providing novel avenues for expanding the donor pool. Additionally, the integration of artificial intelligence and machine learning in organ allocation systems has optimized the matching process, ensuring a more efficient and equitable distribution of organs [8,9]. In the realm of kidney transplantation, innovations such as paired kidney exchange programs and the acceptance of marginal and extended criteria donors have revolutionized the landscape. These initiatives have not only increased the availability of kidneys but have also paved the way for better outcomes and reduced waiting times. Pancreas transplantation, often performed concomitantly with kidney transplantation in diabetic patients, has seen refinements in both surgical techniques and immunosuppressive protocols. Emerging technologies, including bioengineered pancreas constructs and islet transplantation,offer novel avenues for enhancing the treatment of diabetes through transplantation [10,11]. The transplantation of the small intestine remains a complex and challenging frontier, with ongoing research focused on overcoming graft rejection and improving intestinal graft survival. This comprehensive overview aims to provide a glimpse into the dynamic and evolving field of abdominal organ transplantation, highlighting the collaborative efforts of multidisciplinary teams [12]. As the journey of advancements continues, addressing ethical, social, and economic dimensions will be crucial to ensuring that the benefits of these innovations are accessible to all in need of this life-saving therapy.
