Robotic-assisted microsurgery for lymphedema treatment

The recent development of robotic-assisted microsurgery and supermicrosurgery has raised great expectations to support some of the most demanding microsurgical procedures, which are applied in lymphatic reconstructive surgery to restore lymphatic vascular integrity and treat lymphedema. Procedures such as the establishment of lymphovenous anastomosis (LVA), the harvest of lymph nodes from anatomic locations that reduce donor-side morbidity and the transplantation of the vascularized lymph node flaps (VLNT) present procedures necessitating extreme precision and dexterity in often difficult-to-reach areas, thus pushing the physical limitations of the performing microsurgeon. Despite being limited in number, recent preclinical and clinical studies of independent groups using different robotic systems demonstrate the feasibility of robotic technology to perform supermicrosurgical procedures successfully. The robotic assistance offers unparalleled precision, refining the surgical techniques and minimizing potential side effects, with clinical outcomes comparable to the conventional techniques. Although the relative disadvantages of robotic assistance mostly appear to be related to adequate training and the prolonged learning curve, the technology promises to revolutionize the field of supermicrosurgery and improve the clinical outcomes of lymphatic reconstructive surgery.
