Outcomes of Breast Reconstruction After Mastectomy Using Deep Inferior Epigastric Perforator Flap After Massive Weight Loss

Challenges in Autologous Breast Reconstruction: A Review of Recommendations

Breast reconstruction is an integral part of breast cancer treatment and offers significant psychosocial benefits for patients undergoing mastectomy as a part of their treatment plan. Autologous breast reconstruction (ABR) utilizes a patient's own tissue to reconstruct the mastectomy defect, obviating the need for the implantation of a foreign object. As the field of plastic surgery progresses, ABR has become an excellent option for the recreation of a native breast mount. With that said, there are patient populations who present unique challenges when optimizing an aesthetic ABR result. We aim to discuss these challenging groups, including patients with both high and low body mass index (BMI), patients with a history of massive weight loss, patients who require post-mastectomy radiation therapy (PMRT), and patients electing for unilateral procedures where the surgeon attempts to match the reconstructed breast with the native breast. In our discussion, we review the literature recommendations for management as well as our experiences with our own patient cases. Ultimately, we believe this procedure can be performed in a wide variety of patient types and can be offered to those who may not be considered the "ideal" candidate.

Autologous Breast Reconstruction after Massive Weight Loss: Understanding Risks in a Growing Population

BACKGROUND

Massive weight loss (MWL) may have suboptimal effects on tissues used for autologous reconstruction. With the rising rates of obesity and bariatric surgery, more patients who have experienced MWL will be presenting for breast reconstruction. The authors hypothesize that autologous breast reconstruction in patients with a history of MWL will have more complications and require more revisions compared with reconstruction in patients without a history of MWL.

METHODS

A retrospective review was performed on patients who underwent autologous breast reconstruction by five microsurgeons at an academic institution from 2009 through 2020. Patients with a history of bariatric surgery or greater than 50-pound weight loss were identified and compared with patients who had not experienced MWL. Analysis compared demographics, operative details, complications, revision rates, and BREAST-Q scores.

RESULTS

Of 916 patients who underwent 1465 flaps, 39 patients with MWL (4.3%) underwent 68 flaps (4.6%), and 877 patients without MWL underwent 1397 flaps. MWL patients were more likely to require blood transfusions postoperatively ( P = 0.005); experienced more surgical-site infections ( P = 0.02), wound-healing complications of flap ( P = 0.007) and donor sites ( P = 0.03), and late partial flap losses ( P = 0.03); and required more revisional surgery for flap ( P = 0.009) and donor sites ( P = 0.01). BREAST-Q scores were not statistically different for satisfaction with breasts or surgeon but were lower in MWL patients for psychosocial ( P = 0.01) and sexual well-being ( P = 0.04).

CONCLUSIONS

Reconstructive surgeons should expect increased postoperative complications when performing autologous breast reconstruction in patients who have experienced MWL. These patients should be counseled on the possibility of an increased risk of postoperative complications and need for revisional surgery.

Autologous Breast Reconstruction with Bilateral Stacked Free Flaps in Massive Weight Loss Patients

Patients with a history of massive weight loss who are undergoing autologous breast reconstruction after mastectomy represent a unique surgical challenge. Although these patients often have an abundance of excess skin, it may be difficult to acquire sufficient tissue volume for adequate reconstruction of bilateral breasts using single flap techniques due to the paucity of subcutaneous fat. Stacked flap techniques have emerged as an effective method in thinner patients with suboptimal fat distribution who desire autologous breast reconstruction. This can serve as an ideal strategy, specifically in this patient population, when it serves the dual function of providing adequate volume for bilateral breast reconstruction and the secondary benefit of removing the excess skin present after massive weight loss. In this article, we discuss surgical techniques used during two cases of bilateral stacked flap breast reconstruction in cancer patients subsequent to massive weight loss.

Mastopexy on Reconstructed Breast Following Massive Weight Loss: An Innovative Technique Using Dermo-Capsular Flaps

BACKGROUND

We have developed a dermo-capsular flap mastopexy technique for patients who have experienced massive weight loss after breast reconstruction. The aim of this technique is to lift the inframammary fold, adequately cover the implant, and remove excess skin, elevating the breast and obtaining symmetry with the contralateral breast.

METHODS

Between January 2014 and February 2017, we performed this technique on 20 women who were candidates for second-stage breast reconstruction following nipple-sparing mastectomy. All patients had experienced substantial weight loss (> 15 kg) and presented with ptosis after first-stage reconstruction.

RESULTS

There were 8 patients with bilateral reconstruction following bilateral mastectomy (4 with bilateral nipple-sparing mastectomy). There were 12 patients with unilateral mastectomy, all with contralateral breast ptosis treated by augmentation via inverted-T mastopexy (n = 7) or crescent mastopexy (n = 5). The average lift of the nipple-areola complex was 5 cm (range 2-8 cm). The average follow-up was 12 months (range 4-36 months). Two patients had complications, including partial wound dehiscence (in a heavy smoker) and recurrence of breast asymmetry.

CONCLUSIONS

Implant breast reconstruction after massive weight loss is still possible even in the setting of thin, ptotic, and anelastic breast tissue. Our inverted-T dermo-capsular flap mastopexy technique for reconstructed breast is safe and effective with good outcomes and high patient satisfaction.
