Brief Summary
Endoscopic video-assisted nipple-sparing mastectomy (E-NSM) is an advancement in minimally invasive breast surgery designed to reduce surgical trauma and improve cosmetic outcomes while maintaining strict oncologic safety. The procedure will be carried out by a dedicated surgical team in which at least one operator holds certified laparoscopic surgical training issued by a recognized scientific society, ensuring appropriate technical expertise and adherence to surgical safety standards.

Outcome Measures
Primary Outcomes (3)
Rate of completion of the procedure endoscopically without conversion to open surgery.
Number of procedure not converted to open surgery on the total of study procedures.
At surgery
Surgery time
Average and median duration of endoscopic dissection, including creation of the working space.
At surgery
Feasibility of immediate reconstruction
The feasibility and type of immediate reconstruction performed (direct-to-implant or two stage) measured as the number immediate rescotruction on the number of total surgery performed.
At surgery
Study Arms (1)
Endoscopic video-assisted nipple-sparing mastectomy (E-NSM)
EXPERIMENTALAll enrolled patients will undergo endoscopic video-assisted nipple-sparing mastectomy (E-NSM) with immediate breast reconstruction (implant-based or pre-planned alternative reconstruction).
Interventions
Endoscopic video-assisted nipple-sparing mastectomy (E-NSM) is an advancement in minimally invasive breast surgery designed to reduce surgical trauma and improve cosmetic outcomes while maintaining strict oncologic safety. Recent prospective studies and meta-analyses have shown encouraging results in terms of technical feasibility, reduced flap-related complications, and higher patient satisfaction compared with the conventional open approach.
Eligibility Criteria
You may qualify if:
- Female patients aged ≥18 years
- Candidates for nipple-sparing mastectomy (NSM) with immediate reconstruction
- Histologically confirmed invasive carcinoma cT1N0, or carriers of pathogenic germline mutations undergoing prophylactic mastectomy
- Breast size I-III and absence of significant glandular ptosis
- Signed informed consent
You may not qualify if:
- Inflammatory breast cancer
- Locally advanced clinical stage (cT2-T4 or N+)
- Ductal carcinoma in situ (DCIS) without invasive component
- Previous radiotherapy to the affected breast
- Locoregional recurrence
- Clinical conditions contraindicating prosthetic reconstruction
- Indication for skin-sparing (SSM) or skin-reducing mastectomy (SRM)
- Ongoing or completed neoadjuvant chemotherapy before surgery
- Refusal or inability to sign informed consent
- Inability to complete scheduled follow-up
