The Study of the hemodynamic, histological and laboratory changes after extended hepatectomy in porcine model

Abstract

Background/Purpose: After extensive hepatectomy with an insufficient liver volume or after liver transplantation with a small-for-size liver graft, the patient’s survival is dependent on liver regeneration. A large animal model, such as pig, is extremely useful in order to reproduce and understand the small-for-size syndrome (SFSS). This study had three main aims. Firstly, to investigate the hemodynamic, biochemical and histological changes after extended hepatectomy. Secondly, it was carried out in order to create a new porcine model for SFSS after extensive hepatectomy. Last but not least, to examine the role of simultaneous splenectomy in the prevention of SFSS.Methods: In the present study we used twenty-three domestic Landrace pigs, weighing 28.3 ± 3 kg (aged 19-21 weeks). We describe our detailed surgical procedure for 75-80% partial hepatectomy in porcine model, using for the hepatectomy the saline-coupled bipolar sealing device (Aquamantys®). Eighteen pigs were randomly divided ...
