Lymphedema is a chronic, progressive, and debilitating disease of the lymphatic system with no current cure. Physiologic procedures, which address the underlying pathophysiology of lymphatic dysfunction, have gained traction in both treatment and prevention of lymphedema. This narrative review examines current physiologic lymphedema surgical techniques and emerging developments in this rapidly evolving field. While the two most common physiologic surgeries remain lymphovenous bypass (LVB) and vascularized lymph node transfer (VLNT), newer physiologic surgery techniques such as vascularized lymph vessel transfer (VLVT) and lymph node to vein anastomosis (LNVA) have been described in an effort to reduce donor site morbidity, with early promising clinical outcomes. The use of bioengineering with stem cells, pro-lymphangiogenic growth factors, and biomaterials such as Biobridge can be applied in conjunction with surgery to help promote lymphangiogenesis. Technological advances in robotic surgical systems and 3D exoscopes are helping to make supermicrosurgery more technically feasible and ergonomic, and increasing accessibility to lymphedema surgery. As our surgical armamentarium expands, treatment algorithms must be updated to determine how various surgical techniques can be combined and sequenced, how the indications for physiologic surgery can be expanded, and how surgical treatment can be tailored to the patient and disease process.
