Micro- and supermicrosurgeries have become standard techniques for lymphatic reconstruction. As increasingly smaller vessels are being targeted, robotic-assisted surgery has emerged as a new approach to push reconstructive limits owing to its ability of motion scaling and providing better accessibility of deep anatomical regions. The precision of the robot is achieved at the expense of operating speed among other variables; therefore, the surgeon must weigh the enhanced dexterity against the additional operating time and cost required for the robotic surgical system itself to ensure optimal resource utilization. Here we present a case series of 8 patients who underwent robot-assisted lymphatic microsurgery for omental flap transfer to the axilla and lympho-venous anastomosis. The Symani® Surgical System was used with a conventional microscope or 3D exoscope. The use of 3D exoscope provided clear benefits in terms of surgeon positioning. Moreover, access to the recipient vessels near the thoracic wall was significantly improved with the robotic setup. In addition, suture precision was excellent, resulting in patent anastomoses. Operating time for anastomosis was comparable to that for manual anastomosis and demonstrated a steep learning curve. The benefits of robotic systems in operating fields with good exposure require further evaluation. However, owing to longer instruments, additional stability, dexterity, and motion precision, robotic systems offer a marked advantage for operating in deep anatomical planes and on small structures. A potentially new field for the implementation of robotic surgery is central lymphatic reconstruction. Progress in terms of operating time and cost is crucial, and future research should validate the effectiveness of robotic-assisted surgery in larger clinical studies.
