Patient-Reported Assessment of Functional Gait Outcomes following Superior Gluteal Artery Perforator Reconstruction

Patient-Reported Outcomes Following Breast Reconstruction With the Transverse Myocutaneous Gracilis Flap Using the BREAST-Q and Lower Extremity Function Scale

BACKGROUND

The transverse myocutaneous gracilis (TMG) flap is a viable and safe option for breast reconstruction in patients with limited abdominal tissue or other contraindications for abdominal-based flaps. Although it is one of the most common flaps employed for breast reconstruction, data on patient-reported outcomes is limited.

OBJECTIVES

The authors seek to evaluate patient satisfaction and aesthetic outcome after breast reconstruction with the TMG flap.

METHODS

All patients who underwent breast reconstruction with a TMG flap between March 2010 and October 2020 were identified. Invitation to a digital version of the BREAST-Q reconstructive module and the Lower Extremity Function Scale (LEFS) was sent to 105 patients. Patient demographics, complications, and surgical details were collected and retrospectively analyzed. BREAST-Q and LEFS scores were calculated and compared to the literature.

RESULTS

Eighty-two patients participated in the study. Median follow-up was 5.9 years, with a mean patient age of 45.7 years. Most patients (90.2%) received treatment due to previous cancer of the breast, and 17.1% underwent immediate reconstruction. The mean score for "Satisfaction with Breast" was 66/100. Postoperative lower extremity function was high, with a median LEFS score of 78/80. A LEFS score below the median value was found to be significantly associated with active smoking (P = .049). Patients also reported high satisfaction with donor sites (8/11).

CONCLUSIONS

Patient satisfaction and aesthetic outcome after breast reconstruction with TMG flaps is high and comparable to other common techniques. Lower extremity function is not impaired after flap harvest.

A V–Y fasciocutaneous flap for perineal reconstruction following abdominoperineal resection: quicker and better than a myocutaneous gluteal flap?

Background

Abdominoperineal resection in patients with anorectal malignancies may require flap reconstruction for large perineal defects as an adjunct to the oncologic surgery. Perineal reconstruction should be timely, safe, and yield good long-term functional results. There is no agreement on the ideal approach.

Methods

We performed a retrospective observational cohort study to compare clinical outcomes and post-operative complications between a musculocutaneous gluteal flap and a fasciocutaneous V–Y flap for perineal reconstruction. We included all patients who underwent abdominoperineal resection at Karolinska University Hospital between 2016 and 2019. Patient demographics and comorbidities, as well as treatment data, post-operative complications, and follow-up data, were collected from medical records.

Results

A total of 44 patients were included with a mean age of 65 years where 73% were men. Reconstruction was made with a musculocutaneous gluteal flap in 19 patients (43%) and with a fasciocutaneous V–Y flap in 25 patients (57%). Flap-related post-operative complications occurred in 39% of the patients and the incidence did not differ between the groups (p = 0.831). Neither operative time, time to ambulant mobility, time to drain removal, nor time to epidural removal differed between the groups (p > 0.05). Four patients in the gluteal flap group and one patient in the V–Y flap group presented with long-term complications.

Conclusions

Post-operative complications are common after perineal reconstruction following abdominoperineal resection regardless of reconstructive approach. Our study confirms that both a fasciocutaneous and a musculocutaneous flap are acceptable options for perineal reconstruction.

Safety and Efficacy of the Superior Gluteal Artery Perforator (SGAP) Flap in Autologous Breast Reconstruction: Systematic Review and Meta-Analysis

Simple Summary

Breast reconstruction following mastectomy is associated with higher patient satisfaction and quality of life. Autologous breast reconstruction has become increasingly popular in recent decades and offers good long-term results. While the abdomen is typically chosen as the donor site for autologous breast reconstruction, it can be unsuitable for some patients. In this setting, different donor sites, such as the buttocks, can be used to reconstruct the breast. The superior gluteal artery perforator (SGAP) flap is a safe alternative to the deep inferior epigastric artery perforator (DIEP) flap and provides good esthetic results, making it a valuable option for breast cancer patients desiring a postmastectomy autologous breast reconstruction.

Abstract

(1) Background: The superior gluteal artery perforator (SGAP) flap is a prominent technique for autologous breast reconstruction. Unlike other commonly used techniques, current literature on the safety and efficacy of the SGAP flap is heterogenous and limited. The aim of this article was to perform a systematic literature review and meta-analysis of postoperative outcomes and complications associated with SGAP flap autologous breast reconstructions. (2) Methods: A systematic literature search of multiple databases was performed using the PRISMA guidelines. We included articles evaluating SGAP flaps in autologous breast reconstruction. Outcomes and complications were recorded and analyzed. Proportions and their 95% confidence intervals (CIs) were calculated in a random-effects meta-analysis. (3) Results: Fourteen studies meeting inclusion criteria, representing a total of 667 SGAP flaps, were included. The total flap loss rate was 1% (95% CI 0–3%), partial flap loss rate was 1% (95% CI 0–3%), hematoma rate was 3% (95% CI 1–6%), emergent surgical re-exploration rate was 5% (95% CI 2–9%), and overall donor-site complications were 12% (95% CI 4–23%). (4) Conclusions: This systematic review and meta-analysis provide comprehensive knowledge on the efficacy and safety of the SGAP flap in autologous breast reconstruction. It demonstrates its overall safety and low complication rate, validating its important role as an effective option in breast reconstruction.

Latest Advancements in Autologous Breast Reconstruction

LEARNING OBJECTIVES

After studying this article, the participant should be able to: 1. Understand the available donor sites for autologous breast reconstruction. 2. Describe the advantages and limitations of each donor site. 3. Provide a rational, algorithmic preoperative evaluation and approach for patients seeking autologous breast reconstruction. 4. Develop an effective postoperative monitoring system to minimize complications and maximize salvage of microvascular thromboses.

SUMMARY

Breast reconstruction remains at the heart of the field of plastic and reconstructive surgery, and it is continuously evolving. Tremendous advances in breast implant technology and supplemental products, particularly acellular dermal matrices, have revolutionized breast reconstruction in the modern era. However, microvascular free flap breast reconstruction has also witnessed profound advancements with exceptionally high success rates, with the ability to provide the most durable and natural breast reconstruction. Although the pendulum oscillates between prosthesis-based reconstruction and autologous tissue, the present synopsis will focus on autologous free flap breast reconstruction from an historical perspective, recent advancements in microsurgery, and the future of autologous breast reconstruction.
