Overview
The goal of this clinical study is to evaluate the effectiveness and safety of a novel breast reconstruction technique combining endoscopic nipple-sparing mastectomy (E-NSM) with immediate multistage fat grafting (IMFG) in female patients aged 18 years or older with clinical stage 0 to II breast cancer who desire immediate breast reconstruction. The main questions it aims to answer are: Does the combined E-NSM and IMFG approach improve patient-reported outcomes, including satisfaction with breasts and physical well-being, as measured by the BREAST-Q questionnaire? What is the frequency and nature of surgical complications associated with this technique, such as wound healing, hemorrhage, and need for reoperation? Participants will undergo endoscopic nipple-sparing mastectomy with lymph node surgery followed by immediate multistage fat grafting for total breast reconstruction via a small cosmetic axillary incision. They will also complete the BREAST-Q questionnaire and receive clinical and photography-based assessments at follow-up visits to evaluate aesthetic and quality-of-life outcomes.
Interventions
- Procedure endoscopic nipple-sparing mastectomy (E-NSM) with immediate implant-based reconstruction
The patient was positioned supine, with the operative-side arm wrapped and elevated to expose the axillary fossa endoscopically. After SLN excision and frozen-section analysis, the lateral edge of the pectoralis major was exposed. A sterile glove finger was used to sheath a wound retractor.Using the electrosurgical hook, the retromammary fat was dissected from the pectoralis major to a defined boundary, carefully preserving the serratus anterior fascia laterally and inferolaterally. Dissection t
Primary outcome measures
