The pig has a particularly high translational value due to its similar overall anatomy and physiology, thus used as a first choice in many fields of surgical research. In cardiovascular procedures, it contributed to stents development, coronary bypass grafting improvement and heart valve xenotransplantation. A particular focus will be done in the future to improve the models and consequently the reliability of the preclinical findings. In digestive surgery, the utility of pigs has been diverse, with the development of meshes for abdominal defects repair or improvement of surgical procedures aiming at compensate functional defects. A particular utilization has been made in liver regeneration and transplantation procedures, for which the future perspectives are wide, and in metabolic surgery research for metabolic diseases interventional therapy. In endocrine surgery, the use of the pig has mainly consisted in the development of pancreas and islets transplantation for type 1 diabetes therapy, whereas the research on the other glands is less represented. Osteoarticular and neurosurgery are fields where the use of the pig is increasing: for ethical reasons instead of non-human primate models in neurosurgery but also because the rapid growth of this species allows to test the biomechanical properties of orthopedic devices in context of skeletal growth. More generally, the pig has a particular present and future involvement for testing new surgical equipment or bioengineering solutions, developing new minimally invasive approaches and robotic surgery training, regardless of the field. Finally, pig-to-human organ xenotransplantation represents a major translational surgery challenge. If the research has reached a milestone with some living patients grafted with heart or kidney from pigs with multiple genetic modifications, additional findings are required to demonstrate the safety and the long-term benefit and to extend it to other organs like the liver. In summary, the pig model has led to many advances in surgical research, with future prospects focusing primarily on xenotransplantation. However, the use of the pig in biomedical research will have to deal with growing societal ethical expectations.</p>","PeriodicalId":12222,"journal":{"name":"European Surgical Research","volume":" ","pages":"1-13"},"PeriodicalIF":1.7,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144005476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One must consider several factors; one of these, of utmost importance, is the translational value of the animal model. The sheep, as a translational surgical model, possesses a multiple of advantages that makes it one of the preferred models in several research domains. Sheep are the state-of-the-art test models for cardiovascular research and safety studies required for approval of cardiovascular implantable devices; the sheep's heart size, cardiac muscle, heart valves and the mechanical, haemodynamic and coagulation parameters are very similar to humans. Furthermore, the pregnant sheep/lamb are robust models for studying neonatal adaptation and placental physiology due to its physiological similarities with humans. Its placental structure supports efficient gas exchange, resembling human oxygen transfer mechanisms. The ovine model is mainly used in studies of adaptation at birth, foetal physiology during labour and in congenital diaphragmatic hernia. The sheep model is also used in several orthopaedic pre-clinical models, mainly in the study of critical bone defects, cancellous bone healing, osteomyelitis and joint replacement surgeries. It is also a preferred model of bone healing in osteoporosis. Moreover, the sheep has gained popularity as a model of osteoarthritis (OA); it is a validated model of surgically induced OA. Several therapeutic modalities can be evaluated using validated outcome measures such as, kinetics, kinematics, imaging, repeated arthroscopic grading, synovial fluid analysis and biomarkers. The ovine model, because of its size, is the closest to humans for the evaluation of spinal surgery techniques, devices and spinal fusion biological enhancers/ cancellous graft replacement. Finally, we will outline the different specificities of sheep analgesia and anaesthesia. Challenges encountered in ruminant anaesthesia are mainly in relation with their digestive physiology that creates a high risk of regurgitation during anaesthesia and a hindrance of diaphragm/respiratory movements due to rumen repletion and meteorism. Fasting regimen and management of recovery should encompass strategies that limit the starving sensation and allow for reduced social isolation. Clarification of the interactions between scientific objectives and anaesthesia-analgesia protocols prevents conflicts between the ethics and the purpose of the experiment while allowing for development of model-specific anaesthesia and pain management protocols. The sheep has become a popular model because of its size, availability, robustness, cost and ease of handling. Furthermore, as a preclinical model, the same validated objective outcome measures used to measure success in humans can apply to sheep.</p>","PeriodicalId":12222,"journal":{"name":"European Surgical Research","volume":" ","pages":"1-9"},"PeriodicalIF":1.7,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143999320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are widely utilized in biomedical research due to their anatomical and physiological similarities to humans. Examples of commonly used species include the genera Macaca (macaques), Papio (baboons), Aotus (owl monkeys), Callithrix (marmosets), Saimiri (squirrel monkeys), and Chlorocebus (vervet monkeys). NHP models have played an instrumental role in the development of surgical techniques, each being balanced with a unique set of advantages and shortcomings. With the appropriate selection of species and anatomy, animal models can be used to provide insight into the pathophysiology of diseases, to confirm the feasibility of new surgery technologies, to assess the potential efficacy of new surgical techniques for specific clinical outcomes, and to establish reasonable safety of new techniques for specified clinical use. Robotics have augmented surgical precision for microinjections and a brain-spine robotic interface used in gait restoration, illustrating the translational potential of NHP models in human neurological research. Recent studies highlight protocols for procedures such as tubectomy and spinal cord access with minimal postoperative risk, expanding surgical possibilities. This review provides an overview of the recent advancements made in surgery in NHP models and the translation of these techniques to the clinical setting. Surgical refinements not only enhance animal welfare but also improve the quality of experimental outcomes.
