[Robot-assisted Microsurgery for Autologous Breast Reconstruction - Robotic Breast Reconstruction].

Background: With the introduction of novel surgical robots and surgical microscopes for the special needs of open microsurgery, the concept of robotic-assisted microsurgery is gaining popularity. While initial preclinical studies indicate a steep learning curve, favourable ergonomics and improved precision, albeit with an increased operating time, data on the clinical application of the new systems is still limited. This study describes our first clinical experience with robotic-assisted autologous breast reconstruction and outlines the opportunities and limitations of the approach.

Patients and methods: Our retrospective data analysis included a total of 28 patients who underwent unilateral robotic-assisted autologous breast reconstruction between July 2022 and August 2023. We applied a combined approach using the Symani Surgical System together with the RoboticScope. Descriptive evaluation of patient characteristics, surgical data and complications was performed.

Results: Average patient age was 54.3±11.1 years and average BMI was 26.5±3.5 kg/m². Twenty-six patients received a DIEP flap and 2 patients received a PAP flap, the flaps being connected to the internal mammary artery in 22 cases, to a perforator of the internal mammary artery in 5 cases, and to a branch of the thoracodorsal artery in one case. The average incision-suture time was 267±89 min, with an average ischaemia time of 86±20 min and duration of the arterial anastomosis of 29±12 min. In two cases, immediate intraoperative anastomosis revision was performed, but no flap loss occurred.

Conclusion: The results of this study demonstrate the safe feasibility of robot-assisted autologous breast reconstruction using a combination of Symani and RoboticScope. In the future, special attention should be paid to minimally invasive techniques of flap harvest and connecting vessel preparation.
