Objectives: Owing to an imbalance between demand and supply, which is more prominent in pediatric transplant, every year more patients lose their lives on waiting lists. In addition to the use of deceased-donor split and living-donor organs, xenotransplant could provide a solution if associated problems, such as immunologic and physiologic ones, are solved. This study sought to analyze the surgical aspects for liver xenotransplant in a porcine model. Materials and Methods: Landrace pigs (n=22, 23 to 37 kg) underwent a laparotomy under general anesthesia. The hepatic hilum was prepared and the common bile ducts, common hepatic artery, portal vein, supra- and infrahepatic inferior vena cava were identified. The length and diameter of each vessel and bile duct and the weight of the liver were measured. Results: Pearson tests showed a clear correlation between the increase of the pigs’ weight and the livers’ weight, and the length of the vessels and the bile ducts. We did not find a clear correlation between the increase of the pigs’ liver weight and the diameters of the vessels and the bile duct. Conclusions: As the first reporting, this study on xenotransplants from the surgical point of view, we postulate that it could be possible to estimate the size of the liver and the proper length of its vessels and bile duct by weighing only the pigs. It was not feasible to match the diameter of mentioned structures by the livers’ weight. However, the weight of pig’s liver as well as vascular anatomy of pigs appeared to be suitable alternative for the human liver.
