Five robot-assisted breast surgeries
What each operation actually involves, who it is for, how it is performed, and the recovery to expect. Written for patients and treating physicians reviewing options.
Robotic nipple-sparing mastectomy
Complete removal of breast tissue through an axillary or inframammary port while preserving the skin envelope and the nipple-areolar complex. The robotic approach reaches the plane between the skin and the breast tissue at angles the human wrist cannot, so the skin's blood supply and the nipple's sensory nerves are protected.
Who it is for
- Early-stage breast cancer with tumours up to ~5 cm
- No direct involvement of skin, nipple, or chest wall
- Good-responders after neo-adjuvant chemotherapy
- Bilateral risk-reducing surgery in BRCA carriers
- Not suitable when the tumour sits within 2 cm of the nipple, or in advanced skin-involving disease
Outcomes
- 100% negative margins in the published series
- 0% re-excision
- 0% recurrence at follow-up in the published cohort
- Preserved nipple sensation in the large majority of cases
How it is performed
Under general anaesthesia, a concealed circumareolar or inframammary port is created and the da Vinci system is docked. Working from within the breast cavity, the surgeon dissects the plane beneath the skin and around the nipple-areolar complex. Sub-areolar tissue is sent for frozen-section pathology intra-operatively - if the margin is involved, the operation is safely converted to skin-sparing. The mastectomy specimen is delivered en bloc through the port, and reconstruction (implant or robotic LD flap) is carried out in the same anaesthesia.
Recovery
Two to three nights in a private hospital room, then oral analgesia at home. Most patients drive at 10-14 days, return to office work at 3-4 weeks, and reach a full recovery around 6 weeks. Follow-up MRI is scheduled at 6 months and annually thereafter.
Robotic skin-sparing mastectomy
When the nipple-areolar complex has to be sacrificed - because of tumour proximity, Paget's disease, or an involved sub-areolar frozen section - the skin envelope is still preserved and reconstruction is carried out in the same operation. The cosmetic result is materially better than a conventional total mastectomy, and the oncological safety is unchanged.
Who it is for
- Sub-areolar involvement discovered on frozen section during a planned NSM
- Paget's disease of the nipple
- Central-quadrant tumours abutting the nipple-areolar complex
- Locally advanced disease with skin edema but not skin infiltration
- Not suitable when there is direct skin infiltration or an inflammatory carcinoma pattern
Outcomes
- Equivalent local recurrence and survival to radical mastectomy in appropriately selected patients
- Cosmetic outcome materially better than a conventional total mastectomy
- Reconstruction options are not compromised by the SSM approach
How it is performed
The dissection plane and robotic approach mirror the NSM technique above, except the nipple-areolar complex is included with the mastectomy specimen. The remaining skin envelope is preserved and immediate reconstruction (implant, LD flap, or delayed with tissue expander) is performed. Nipple reconstruction can be considered as a separate stage 6-9 months later once the reconstructed breast has settled.
Recovery
Similar to NSM: two to three nights in hospital, driving at 10-14 days, office work at 3-4 weeks. Full-contact sport is deferred to 8 weeks. A nipple-tattoo or 3D-nipple option is discussed later.
Robotic oncoplastic lumpectomy
Breast-conserving surgery combined with immediate reshaping - so the breast is not left with the collapsed contour that follows a conventional wide local excision. Robotic assistance improves precision at the excision margin and enables reshaping techniques that are difficult through an open approach.
Who it is for
- Early-stage cancers where breast conservation is oncologically feasible
- Tumours up to ~4 cm relative to breast volume (roughly < 20% of the breast)
- Patients who want to retain the natural breast rather than proceed to mastectomy
- Adjuvant radiotherapy after surgery is planned (a lumpectomy standard)
- Not suitable when tumour-to-breast ratio makes an acceptable cosmetic result impossible, or when the patient cannot tolerate post-op radiation
Outcomes
- Cosmetic outcome measurably better than conventional wide local excision
- No compromise on breast conservation safety when patient selection is right
- Reduces the psychological gap between diagnosis and normal life
How it is performed
Under general anaesthesia, the tumour is localised (by clip, radioactive seed, or ICG-Firefly for non-palpable lesions) and excised with adequate margins under robotic guidance. The residual cavity is filled by rotating adjacent glandular tissue, and the skin is closed along Langer's lines for a scar that fades into a natural crease. Sentinel-node biopsy is performed through the same anaesthesia when indicated.
Recovery
Day-care to one-night hospital stay. Most patients drive at 3-5 days and return to office work in the same week. Full recovery around 3 weeks. Adjuvant radiotherapy typically begins 4-6 weeks post-op.
ICG-Firefly guided excision of non-palpable lesions
A technique pioneered by this programme for excision of lesions that cannot be felt on examination - post-chemo residuals, DCIS, screen-detected cancers, and benign lesions in dense breasts. Fluorescent indocyanine-green dye is injected around the lesion and made to glow under the da Vinci's near-infrared Firefly camera, so the surgeon can excise exactly the labelled tissue rather than a wide field around a wire-guided location.
Who it is for
- Non-palpable cancers picked up on mammography or MRI
- DCIS and other pre-invasive lesions where wide margins matter but wide dissection does not
- Residual disease after neo-adjuvant chemotherapy where the tumour has clinically vanished
- Benign lesions in dense breasts where a wire-guided approach would leave an unnecessary scar
- Not suitable when the lesion is too deep for reliable ICG deposition or the patient has iodine hypersensitivity
Outcomes
- 100% intra-operative Firefly visibility of ICG-labelled lesions in the published series
- 100% clip-retrieval success
- 100% negative surgical margins
- Suitable substitute for wire-guided localisation with a materially better cosmetic outcome
How it is performed
Under ultrasound guidance, ICG dye is injected perilesionally or at the biopsy-clip site immediately before surgery. A concealed circumareolar or inframammary port is created and the da Vinci system is docked. Firefly near-infrared imaging is activated; the ICG-labelled tissue glows brightly and is excised en bloc with adequate margins, including the localisation clip. The specimen is checked on the back table to confirm containment.
Recovery
Day-care or one-night stay depending on lesion size and location. Most patients return to office work within a week. Adjuvant treatment - if needed - is planned once the final pathology is available at 5-7 days.
Robotic latissimus dorsi flap reconstruction
The latissimus dorsi flap is the workhorse of breast reconstruction. Conventionally it demands a 15-25 cm back scar and repositioning of the patient mid-surgery. Robotic assistance harvests the same muscle through the axillary port that was used for the mastectomy - no back scar at all, no repositioning, and the operating time is roughly halved.
Who it is for
- Patients undergoing NSM or SSM who prefer autologous (own tissue) reconstruction
- Failed or contraindicated implant-based reconstruction
- Partial mastectomy defects where the residual breast needs volume replacement
- Salvage reconstruction after implant complications
- Not suitable when the latissimus muscle has been previously divided or when the thoracodorsal pedicle is compromised
Outcomes
- No back scar at all - the historic reason patients declined LD reconstruction
- No mid-surgery repositioning, reducing anaesthesia time and morbidity
- Reliable well-vascularised autologous tissue with excellent long-term outcomes
- Roughly halved operative time versus open LD harvest (Selber et al.)
How it is performed
Through the same axillary incision used for the mastectomy, the surgeon dissects the plane between the skin and the latissimus muscle under 3D magnified vision. The muscle is mobilised with its thoracodorsal neurovascular pedicle preserved intact, then rotated forward through the axilla into the breast defect. The tissue is shaped to reconstruct the breast contour, and the whole procedure is completed in a single supine position.
Recovery
Three to four nights in a private hospital room. Drain removal typically at day 5-7. Most patients return to office work in 4-6 weeks and full activity around 8 weeks. There is no visible scar on the back at any stage.
