Brief Summary

Current breast cancer surgery is achieving minimally invasive approach to reduce incision while providing better surgical vision and freedom in mastectomy. Breast reconstruction with free deep inferior epigastric artery perforator (DIEP) flap was considered the gold standard, however, the donor site morbidity remains an endless concern. Here we applied robotic-assisted surgery in both mastectomy and free DIEP flap harvest, so-called Oncoplastic Entirely Robot-Assisted Approach (OPERA). A retrospective chart review identified 14 patients with unilateral breast cancer received robotic-assisted mastectomy and robotic assisted free DIEP flap harvest for breast reconstruction. The patient demographics and mastectomy and flap characteristics were reviewed.
