Envelope mastectomy with immediate reconstruction (EMIR)

Area of Science:

• Surgical Oncology
• Plastic and Reconstructive Surgery
• Breast Cancer Treatment

Background:

• Mastectomy, a common breast cancer treatment, often necessitates complex reconstruction techniques.
• Traditional methods can result in significant scarring and multiple surgical sites.
• There is a need for oncologically safe procedures with improved aesthetic outcomes and patient convenience.

Purpose of the Study:

• To evaluate a novel technique for mastectomy combining oncological safety with aesthetic acceptability.
• To assess the feasibility of immediate breast reconstruction using a latissimus dorsi muscle flap and tissue expander.
• To utilize a single, inconspicuous incision for both the oncological surgery and reconstruction.

Main Methods:

• An envelope mastectomy (skin and nipple sparing) was performed on twelve patients.
• Immediate reconstruction was achieved using a latissimus dorsi muscle flap and a tissue expander.
• Cosmetic outcomes were evaluated through pre- and post-operative photographic analysis by an independent observer.

Main Results:

• No cancer recurrences were observed during the follow-up period.
• The cosmetic assessment yielded a high score of 92% (44 out of 48).
• One case required prosthesis removal due to skin erosion, indicating a minor complication rate.

Conclusions:

• The single-incision mastectomy with immediate reconstruction is an oncologically safe and aesthetically pleasing option.
• This technique is suitable for patients with large, multi-focal, or recurrent breast tumors.
• The mid-axillary incision provides an inconspicuous scar, enhancing patient satisfaction with the reconstructive outcome.
