Background:
The experience of application of robotic surgery platform in the management of breast cancer was limited. The preliminary experience and results of robotic nipple-sparing mastectomy (R-NSM) and immediate breast reconstruction (IBR) with Gel implant was reported.
Methods:
The medical records of patients who underwent R-NSM and IBR with Gel implant for breast cancer during the period March 2017 to October 2017 were collected from single institution. Data on clinicopathologic characteristics, type of surgery, method of breast reconstruction, complications, and recurrence were analyzed to determine the effectiveness and oncologic safety of R-NSM. Patients' oriented cosmetic outcome report was also obtained.
Results:
A total of 15 patients was analyzed, and the mean age of them was 46.5 ± 10.0 years. The pathologic stage was 30.8% ductal carcinoma in situ, 30.8% stage I, 30.8% stage II, and 7.7% stage III. The mean operation time was 282.8 ± 70.4 minutes, and mean hospital stay was 6.7 ± 1.2 days. The positive surgical margin rate was 0%. One patient suffered from delayed axillary wound healing. Two patients (13.3%) with transit nipple ischemia change, but no total nipple areolar complex necrosis case was observed. No local recurrence, distant metastasis, or case mortality was found during mean 6.3 ± 2.1 months follow-up. All 15 patients were satisfied with the postoperative aesthetic outcome.
Conclusion:
From our preliminary experience, R-NSM and IBR with Gel implant is a safe procedure, with good cosmetic results, and could be a promising new technique for breast cancer patients indicated for mastectomy.
