The Present and Future of Robotic Surgery in Breast Cancer and Breast Reconstruction.

Background: Breast cancer is the second most common cancer in women with an improving mortality rate and a growing need for reconstruction following oncologic resection. Advancements in robotic surgery and minimally invasive techniques have offered refinement to traditional open techniques of flap harvest for reconstruction, particularly regarding improved donor site morbidity. Methods: The literature review was based on a PubMed database search using the keyword "Robotic breast reconstruction" in conjunction with the Boolean operators "Flap", "Latissimus", and "DIEP" to specify the search. In total, 106 results were generated, which were then manually reviewed and condensed for a comprehensive stance on the current status, technique, variations, and outcomes for robotic breast reconstruction. Results: Robotic technique has been described for the latissimus dorsi (LD) and deep inferior epigastric perforator (DIEP) flaps for breast reconstruction. For LD, robotic flap harvest reduces donor site morbidity, incisional length, and hospital length of stay, with similar complication rates for seroma/hematoma/infection, and longer operative times. Robotic LD procedures have been described in conjunction with single-site nipple-sparing mastectomy and flap elevation leading to a full minimally invasive resection and reconstruction from one lateral incision. Robotic DIEP harvest offers a considerably smaller fascial incision/rectus muscle dissection and has a comparable complication rate to traditional techniques with shorter hospital length of stay, and improved pain, at the expense of longer operating times. Data on hernia/bulge reduction from robotic techniques is limited and not yet available. Conclusions: Robotic breast reconstruction offers great potential for improving breast reconstruction in terms of donor site morbidity, length of incision, hospital length of stay at the cost of longer operating times, and increased technical skill/specialization, but it has yet to be proven on a large scale with long-term outcome data. Multi-center, prospective clinical data and trials are needed to help elucidate the potential for equivalence and superiority of the minimally invasive approach compared to standard open techniques, but the future is promising for robotic surgery in breast cancer and breast reconstruction.
