A mouse model of SBTX would allow investigators to apply the knowledge of the well‐defined genetics in the mouse to this field of study. Therefore, we have developed a mouse model of heterotopic SBTX using syngeneic C57BL6/J mice. Animals were anesthetized with a combination of ketamine and xylazine. Donor animals underwent midline laparotomy, with isolation of a segment of bowel as an isograft for transplantation to a recipient animal. The bowel was flushed in situ prior to removal of the graft with a Carrel patch of aorta and portal vein. The recipient animal underwent midline laparotomy and preparation of its infrarenal aorta and inferior vena cava for end‐to‐side anastomosis of the graft with 10‐0 nylon. After vascular reperfusion of the graft the ends of the isografted bowel were brought out as stomata. Successful grafts were later assessed for viability by laparotomy or histological examination at the time of sacrifice. Areas of technical difficulty in this model and issues that might improve the experimental results are discussed. This model should allow investigators to apply the well‐defined genetics of the mouse to probe the challenging field of intestinal transplantation. © Wiley‐Liss, Inc.</jats:p>
