Abstract
BACKGROUND: Minimally invasive surgery (MIS) is the technique of choice in selected patients for the treatment of liver tumors. The robotic approach is considered today the natural evolution of MIS. The application of the robotic technique in liver transplantation (LT) has been recently evaluated, especially in the living donation. The aim of this paper is to review the current role of the MIS and robotic donor hepatectomy in the literature and to evaluate the possible future implication in the transplant field. METHODS: We conducted a narrative review using PubMed and Google Scholar for reports published so far, using the following keywords: minimally invasive liver surgery, laparoscopic liver surgery, robotic liver surgery, robotic living donation, laparoscopic donor hepatectomy and robotic donor hepatectomy. RESULTS: Several advantages have been claimed in favor of robotic surgery: three-dimensional (3-D) imaging with stable and high-definition view; a more rapid learning curve than the laparoscopic one; the lack of hand tremors and the freedom of movements. Compared to open surgery, the benefits showed in the studies evaluating the robotic approach in the living donation are: less postoperative pain, the shorter period before returning to normal activity despite sustaining longer operation time. Furthermore, the 3-D and magnification view makes the technique excellent in distinguishing the right plane of transection, vascular and biliary anatomy, associated with high precision of the movements and a better bleeding control (essential for donor safety) and lower rate of vascular injury. CONCLUSIONS: The current literature does not fully support the superiority of the robotic approach versus laparoscopic or open method in living donor hepatectomy. Robotic donor hepatectomy performed by teams with high expertise and in properly selected living donors is safe and feasible. However, further data are necessary to evaluate properly the role of robotic surgery in the field of living donation.
