Innovation and practice of endoscope-assisted nipple-sparing mastectomy combined with immediate subpectoral implant breast reconstruction without gas and mesh through small skin incisions / 中华内分泌外科杂志

ABSTRACT

Objective:To examine the feasibility and safety of endoscopic subcutaneous mastectomy and immediate reconstruction via a small skin incision approach without gas and mesh for early breast carcinomas.Methods:We analyzed 7 patients diagnosed with breast cancer who underwent an endoscopic subcutaneous mastectomy and immediate reconstruction from Jun. to Nov. 2021 using a gasless and meshless small skin incision approach at the Department of Thyroid and Breast Surgery, the First Affiliated Hospital of USTC. Mean age was 44.9 (29-63) years. Clinical stage, postoperative complications and other data of patients were collected. Patients were required to fill in BREAST-Q scale anonymously before and during postoperative follow-up. The difference was considered significant for P < 0.05. Results:The tumors were all unilateral and solitary lesions, with a mean diameter of 1.74 (0-5) cm. The average distance of mass from the nipple on imaging was 2.11cm (range 0 to 4) . Postoperative pathological clinical stage,1 patient was in Tis, 3 patients were in stage I, 2 patients were in stage II and a pathological complete response was achieved in one patient (ypT0pN0cM0 CR) . The mean operative time was 245.3 (195-316) min, the mean intraoperative bleeding volume was 37.1ml, the mean postoperative hospital stay was 5.1 d, and the median follow-up time was 8.8 (6-11.2) months. All the 7 patients had incision healing at the first stage, and no complications such as infection, incision complications, capsular contracture, nipple-areola complex or skin flap necrosis, removal or displacement of breast implant occurred. No local recurrence or metastasis was detected during the follow-up period. Compared with preoperative, the scores of postoperative psychosocial status, chest wall status were lower ( P<0.05) , but still ideal, while breast satisfaction and sexual satisfaction scores were not significantly different from preoperative baseline ( P>0.05) . Conclusion:This study indicates that endoscope-assisted breast reconstruction with gasless and meshless is a safe and feasible surgical intervention method for early breast cancer, with good cosmetic effects, and can be promoted as a new type of breast reconstruction.
