Robotic-Assisted Microsurgery in Lymphatic Reconstruction.

Abstract

Lymphatic reconstruction entails microsurgery of the smallest human vessels with little microsurgical error tolerance. Surgical outcomes are therefore tightly tied to microsurgical performances and can be restricted by physiologic tremor or muscle tiring throughout extensive procedures. Recently introduced highly specialized microsurgical robots are promising to help overcome these human limitations, particularly relevant for lymphatic microsurgery. Ideal indications and setups for these robotic systems, however, are not yet well established. Reviewing the first 5 years of clinical experience with these microsurgical robots revealed a total of 204 robotically performed lymphatic anastomoses. Most reported use cases (84.4%) involved microsurgical reconstructions of lymphatic flow at the upper and lower extremities, of which 42% of patients were treated for breast cancer-related lymphedema. Considering rising cancer incidences and survival rates, these numbers highlight the potential of robotic-assisted microsurgery for this patient group, whereas the concept of robotic-assisted microsurgery per se can aid surgeons to achieve a new level of microsurgical excellence.
