Autotransplantation

Certain abdominal tumors involving the mesenteric root and major vasculature are generally considered unresectable with conventional surgical approaches. Using techniques developed for abdominal organ transplantation, surgeons have successfully resected such tumors in cold preservation solution after removing the tumor-visceral bloc, followed by reimplantation of the involved organs. This method, known as ex vivo resection and autotransplantation, can allow for margin-free resection and complex vascular reconstruction in carefully selected patients. The perioperative management and surgical technique of intestinal and multivisceral autotransplantation is described in this chapter.
