To introduce an surgical technique of endoscopic nipple-sparing mastectomy (NSM) combined with immediate breast reconstruction through simple single-port access that placed in axillary incision.

Between January 2017 and February 2018, 15 female patients with breast cancer (stageⅠ in 5 cases and stage Ⅱ in 10 cases) were treated with endoscopic NSM combined with immediate breast reconstruction through simple single-port access that placed in axillary incision. They were 27-45 years old (mean, 37.5 years). The disease duration ranged from 1 to 24 months (mean, 8 months). The tumor located at the left breast in 8 cases and at the right breast in 7 cases. The diameter of tumor ranged from 1.5 to 3.0 cm (mean, 2.6 cm). The distance between tumor and nipple was 1.8-4.0 cm (mean, 2.3 cm).

After operation, the nipple epidermal necrosis occurred in 1 case, and subcutaneous effusion in 1 case. No subcutaneous emphysema or skin flap necrosis occurred. Postoperative pathological examination showed that 1 case was nipple involvement and was treated with nipple resection. All patients were followed up 7-17 months (mean, 11 months). According to the Harris assessment criteria for appearance of reconstructed breast, there were 4 cases of excellent, 10 cases of good, and 1 case of poor. No tumor recurrence or metastasis occurred during follow-up.

It is a safe and feasible method of endoscopic NSM combined with immediate breast reconstruction through simple single-port access that placed in axillary incision, and can obtain good cosmetic results. It is a new option to breast reconstruction.
