RAPID procedure for colorectal cancer liver metastasis.

Liver transplantation for colorectal cancer has regained renewed interest with reported good overall survival in selected patients. The scarcity of grafts is a major obstacle to wider implementation and exploration of this field of transplant oncology. The use of small segmental auxiliary grafts from deceased or living donors might be one way to expand the donor pool with minimal negative impact on the waiting list for deceased donor transplantation and minimal risk for the donor in case of living donor liver transplantation. This review provides an insight into the physiological background for this technique and summarizes technical and surgical considerations and the experiences with this novel concept. Although the international experience still is very limited, the short term outcome could suggest that this is technically feasible. There is not sufficient data to assess long term oncological outcome. The RAPID concept (i.e. resection and partial liver segment 2-3 transplantation with delayed total hepatectomy) is still an experimental surgical procedure and should be reserved for prospective clinical trials. Herein, we describe the main technical issues of RAPID procedure from deceased and from living donor as well and report preliminary results of the first cases performed worldwide.
