Complications and Patient-Reported Outcomes after Abdominally Based Breast Reconstruction: Results of the Mastectomy Reconstruction Outcomes Consortium Study

Less Is More: The Role of Mesh in Microsurgical Breast Reconstruction with Abdominal Flaps

BACKGROUND

 The use of mesh to reinforce the abdominal wall after abdominal flap harvest has been reported to decrease the risk of bulging and herniation. However, the impact of the plane of mesh placement in relation to the anterior rectus sheath (vs. no mesh) on postoperative abdominal complications remains unclear.

METHODS

 We retrospectively analyzed the length of stay and clinical outcomes in 158 female patients who underwent breast reconstruction with 250 free abdominal flaps. Group 1 consisted of patients who underwent polypropylene sublay-onlay ("sandwich") mesh placement (N = 70) versus polypropylene sublay-only mesh (group 2; N = 54) versus primary fascial repair without mesh (group 3; N = 34).

RESULTS

 Patient demographics and comorbidities were comparable between study groups, except for rates of neoadjuvant chemotherapy (group 1: 53% vs. group 2: 33% vs. group 3: 24% [p < 0.01]), postoperative follow-up in months (group 1: 21.5; group 2: 11.5; group 3: 7.6 [p < 0.01]), and length of stay in days (group 1: 4.9 vs. group 2: 4.4 vs. group 3: 3.3 [p < 0.01]). No differences were observed in breast flap and donor-site complications between study groups. Patients in group 3 required significantly lower oral morphine equivalent units postoperatively compared with those in groups 1 and 2 (group 1:185.5 vs. group 2: 79.7 vs. group 3: 71.6 [p < 0.01]).

CONCLUSION

 Abdominal donor-site closure without mesh was associated with a shorter length of stay and less narcotic intake without an increase in donor-site complications. These findings should be considered when deciding to place mesh for donor-site closure after abdominal flap harvest.

Postoperative complications in breast reconstruction with deep inferior epigastric perforator flap: Looking for evidence

INTRODUCTION

This study investigated patient- and surgery-related risk factors of postoperative complications in microvascular breast reconstruction with deep inferior epigastric perforator (DIEP) flaps.

METHODS

We reviewed the retrospective charts of 212 patients who underwent 250 DIEP flap breast reconstructions between 2018 and 2023. Patient-related factors included demographic characteristics, comorbidities, radiation therapy, and chemotherapy. Surgery-related factors included reconstructive timing and laterality, perforator choice, venous anastomosis technique, and postoperative acetylsalicylic acid (ASA). Early flap complications (first postoperative week) included flap loss, venous congestion, and hematoma. Late flap complications (after the first postoperative week) included wound dehiscence, skin necrosis, fat necrosis, and infection. Donor-site complications (all late) included wound dehiscence, skin necrosis, infection, seroma, and bulging.

RESULTS

The overall complication rate was 31.1%, and flap loss was 1.9%. Obesity and diabetes were significantly associated with late flap complications and donor-site complications (dehiscence, infection, fat necrosis, and seroma). Radiation therapy showed trends toward greater total flap loss, take back, and flap skin necrosis. Age, hypertension, smoking, and chemotherapy were not associated with higher complications. Harvesting multiple versus a single perforator was associated with significantly more donor-site complications. There were significantly more early flap complications and a trend toward more bulging with lateral versus medial row perforators. Venous anastomosis with a coupler versus a suture showed significantly lower flap complications. Reconstruction timing, laterality, vein number, and ASA use did not impact outcomes.

CONCLUSION

Complications increased by obesity, diabetes, radiation therapy, and the use of multiple and lateral row perforators, as well as sutured venous anastomoses. Conversely, outcomes were not affected by age, hypertension, chemotherapy, reconstructive laterality and timing, vein number, coupler size, or postoperative ASA use.

The Impact of Preoperative Radiotherapy and Chemotherapy on Autologous Breast Reconstruction Outcomes-A Retrospective Single-Center Study

BACKGROUND

While radiotherapy (RT) and chemotherapy (CT) significantly improve breast cancer outcomes, they may affect breast reconstruction by causing vascular damage and delayed wound healing. This retrospective study evaluates how preoperative RT, CT, or the combination of both impacts intraoperative and postoperative outcomes in immediate or delayed deep inferior epigastric perforator (DIEP) flap breast reconstructions.

METHODS

We conducted a single-center review of all patients undergoing autologous DIEP flap reconstruction after mastectomy between 2018 and 2024. Patients were divided into four groups: RT only, CT only, a combination of RT and CT, and a control group with no preoperative therapies. Intraoperative and postoperative outcomes were then compared among these groups, with statistical significance defined as p < 0.05.

RESULTS

We included 114 patients representing 141 DIEP-flap breast reconstructions. Flap survival rate was 98.5%. In the univariate analysis, total microvascular recipient site complications were significantly higher in the RT + CT group (14.0%, p = 0.021). Donor-site complication rates differed significantly among the four groups (p = 0.025), with the highest rate observed in the RT + CT group (44.7%). In the logistic regression analysis, ischemia time was found as an independent risk factor for total recipient site complications, but not for microvascular complications (OR = 1.019, 95%-CI = 1.004-1.035, p = 0.014).

CONCLUSIONS

Combined RT + CT significantly increased microsurgical complications. Ischemia time correlated with higher odds of total recipient site complications. Individualized patient management and diminished ischemia time are likely to improve flap survival.

Not All Deep Inferior Epigastric Artery Perforator Flaps Are Created Equal: A Review of Donor-site Morbidity in Abdominally Based Autologous Breast Reconstruction

Background

Breast reconstruction after mastectomy is one of the most common procedures performed in plastic surgery. Autologous reconstruction is associated with better long-term patient satisfaction than implant-based reconstruction but with the requisite donor site and potential for associated morbidity.

Methods

The authors review the literature regarding the technical evolution of abdominally based autologous breast reconstruction and the effect of these changes as well as patient morbidities on bulge, hernia, and all-cause donor-site morbidity.

Results

The impact of patient risk factors on surgical outcomes is evaluated in the context of constantly improving technical surgical innovation. Patients' premorbid abdominal condition and prior abdominal procedures along with traditional complicating factors such as age, obesity, and smoking are associated with increased rates of donor-site complications. Conversely, shorter fascial incisions with or without robotic and laparoscopic assistance are associated with lower rates of abdominal weakness and healing complications than traditional abdominal free flap harvest. Perforator selection and abdominal closure techniques also play a key role.

Conclusions

There are contributions of both patient factors and technical aspects that when optimized can help minimize the risk of donor-site morbidity in deep inferior epigastric artery perforator flap breast reconstruction.

Risks of Autologous Abdominal Free Flap Breast Reconstruction in Patients With Elevated Body Mass Index

Background

Obesity is widely recognized as a significant risk factor for postoperative complications of breast reconstruction. Despite extensive research, there remains a lack of consensus regarding the specific complications and outcomes experienced by patients with obesity who undergo deep inferior epigastric perforator (DIEP) flap reconstruction. To provide a clearer understanding of the challenges faced by patients with obesity, we present a single-center outcome analysis of individuals who underwent DIEP flap reconstruction.

Methods

A cohort of 194 patients who underwent at least 1 DIEP flap was retrospectively analyzed at the University of Nebraska Medical Center utilizing electronic medical records. Patients who underwent DIEP flap breast reconstruction were organized into 5 categories using World Health Organization weight status by body mass index (BMI) obtained from the day of surgery. Surgical complications within 120 days and postsurgical complication-related procedural interventions were also evaluated and compared. Comparisons of variables of interest between weight groups were assessed using Mantel-Haenszel chi-square tests or Spearman correlations.

Results

Increases in patient weight category were associated with increased length of operation (P = 0.003), increased rates of breast fat necrosis (P = 0.04), breast wound dehiscence (P = 0.01), abdominal wound dehiscence (P = 0.02), numbers of abdominal complications (P = 0.001), and rates of requiring an intervention (P = 0.03).

Conclusions

The findings imply that higher BMI values may lead to a higher likelihood of postoperative complications and the need for intervention. It is crucial for patients with obesity to be aware of the elevated risk associated with rising BMI values.

Breast-Related Herniation: A Call for Multidisciplinary Awareness and a Proposal for a Classification

Breast-related herniation (BRH) is a vague term for many clinicians. The absence of a universal nomenclature and the different nature of the herniation process involved, being true or false, contribute to this vagueness. BRH includes a spectrum of disorders ranging from a few congenital breast disorders to commoner herniation processes related to acquired breast diseases. We aim to raise multidisciplinary awareness about BRH by reviewing the related literature and reviewing our experience with BRH. We will also propose a classification for BRH. PubMed and Scopus databases were searched for any herniation disorders that are related to the breast in any clinical or pathological aspect. The literature review revealed 12 various groups of BRHs that we could classify into two anatomical categories: pectoral (mammary) BRH, in which the herniations occur at the pectoral site of the chest wall, and extra-pectoral BRH, in which the herniations occur at an extra mammary site but are related to breast pathologies. Pectoral BRH was further divided into clinicopathological subcategories, including congenital BRH, pulmonary BRH complicating breast cancer and breast infections, factitious BRH, and iatrogenic BRH. Extra-pectoral BRH was further divided into clinicopathological subcategories, including abdominal wall hernias following autologous breast reconstruction (ABR) and herniated siliconomas. Our study group included 19 patients with BRHs, among which congenital BRHs and pulmonary BRHs were the most common. Congenital BRHs are rare and are of main interest to plastic surgeons. However, abdominal wall hernias following ABR, pulmonary BRH, and factitious BRHs are relatively common complications of breast cancer treatment. This calls for a multidisciplinary approach to ameliorate the morbidity of BRHs. Further studies are needed to refine our proposed classification.

Updates on Breast Reconstruction: Surgical Techniques, Challenges, and Future Directions

The increasing global incidence of breast cancer underscores the significance of breast reconstruction in enhancing patients' quality of life. Breast reconstruction primarily falls into two categories: implant-based techniques and autologous tissue transfers. In this study, we present a comprehensive review of various aspects of implant-based reconstruction, including different types of implants, surgical techniques, and their respective advantages and disadvantages. For autologous breast reconstruction, we classified flaps and optimal harvest sites and provided detailed insights into the characteristics, benefits, and potential complications associated with each flap type. In addition, this review explores the emerging role of fat grafting, which has received increasing attention in recent years. Despite advancements, there remains substantial scope for further improvements in breast reconstruction, emphasizing not only aesthetic outcomes, but also a reduction in complications and postoperative recovery. By offering a comprehensive overview of the historical evolution, current landscape, and future prospects of breast reconstruction, this review aims to provide readers with a comprehensive understanding of breast cancer management strategies.

Long-term Donor Site-related Quality of Life after Deep Inferior Epigastric Perforator Flap Breast Reconstruction

Background

Current knowledge about patients' perceptions of the donor site following abdominal-based breast reconstruction and its effect on health-related quality of life (HRQoL) several years after breast reconstruction is limited. This study aimed to assess the long-term effects of deep inferior epigastric perforator (DIEP) flap breast reconstruction on HRQoL, specifically focusing on the abdomen and donor site aspects.

Methods

This retrospective cohort study compared 66 women who underwent DIEP breast reconstruction between 2000 and 2007 with a matched control cohort of 114 women who underwent therapeutic mastectomies without reconstruction in the year 2005. The DIEP cohort of patients completed the BREAST-Q Reconstruction module during an outpatient visit in 2015-2016. The control cohort completed the same questionnaire online in 2016.

Results

The follow-up time was at least 8 years (mean 11.4 ± 1.6 years) postreconstruction for the DIEP cohort and 10 years postmastectomy (mean 11.0 ± 0.3 years) for the control cohort. In the DIEP cohort, 93% reported no donor site pain, 89% had no difficulty sitting up, and 91% had no activity limitations 2 weeks before completing the survey. Patients undergoing DIEP were more satisfied with their abdominal appearance than the control group (adjusted OR, 5.7; 95% confidence interval 1.8-17.6).

Conclusions

A decade postoperatively, DIEP breast reconstruction yields high abdominal donor site satisfaction, with comparable abdominal physical well-being to nonreconstructed women.

Patient-Reported Abdominal Morbidity Following Abdomen-Based Breast Reconstruction

BACKGROUND

 Abdominal wall morbidity occurs with increased frequency following flap harvest in the obese abdomen. Its impact on patient-reported outcomes (PROs) in breast reconstruction has been poorly characterized.

METHODS

 A retrospective review of obese patients undergoing abdominal-based free autologous breast reconstruction was conducted over 15 years. Patient operative characteristics were recorded and outcomes were analyzed. PROs were assessed using the BREAST-Q abdominal survey.

RESULTS

 In total, 75 women (108 flaps) with the mean body mass index (BMI) of 33.2 were included. Flaps included deep inferior epigastric artery perforator (24%), muscle-sparing (43%), and free transverse rectus abdominis myocutaneous flaps (f-TRAM; 33%). World Health Organization (WHO) obesity class, BMI, and flap type did not affect flap failure (1%) or complication rates. Hernia developed in 7%; all necessitated repair. Eight percent developed abdominal bulge; one was repaired. Hernia formation was associated with increased patient age (p < 0.05). Bulge formation occurred more often in f-TRAM donor sites (p = 0.005). BMI, WHO class, flap type, and mesh use were not related to hernia or bulge occurrence in either univariate or multivariate analysis. The survey response rate was 63%. Abdominal Physical Well-Being (proxy for abdominal wall function) and Satisfaction with Abdomen (patient-perceived cosmesis) were similar across flap types, age, and WHO classification groups. Patients with postoperative bulge reported higher abdominal physical well-being scores, regardless of flap type (p < 0.01). Bulge was correlated with lower satisfaction (p < 0.05).

CONCLUSION

 The incidence of abdominal wall morbidity following abdominal free-tissue transfer for breast reconstruction was acceptably low in our population of obese patients. Hernia was a clinically significant complication, warranting surgical repair. Bulge was primarily a cosmetic concern and did not detract from patient-reported abdominal wall function. Age may represent an independent risk factor for hernia formation in this population.

One-stop autologous breast reconstruction: A safe and effective cost-saving pathway

INTRODUCTION

Patients undergoing autologous breast reconstruction usually require further operations as part of their reconstructive journey. This involves contralateral breast symmetrization and nipple-areola complex (NAC) reconstruction. Restrained access to elective operating space led us to implement a one-stop breast reconstruction pathway.

METHODS

Patients undergoing contemporaneous contralateral breast symmetrization and immediate NAC reconstruction with free nipple grafts between July 2020 and June 2021 were identified. A retrospective review of our prospectively maintained database was conducted, to retrieve surgical notes, postoperative complications, and length of inpatient stay. A cost analysis was performed considering savings from contralateral symmetrization.

RESULTS

A total of 50 eligible cases were identified, which had unilateral one-stop breast reconstructions. Complication rates and length of stay were not affected by this approach, with only one free flap being lost for this cohort. This approach resulted in £181,000 being saved for our service over a calendar year.

DISCUSSION

A one-stop breast reconstruction pathway has proven to be safe and effective in our unit. During these uncertain times, it has streamlined the management of eligible patients, while releasing capacity for other elective operations. Patients avoid having to wait for secondary procedures, finishing their reconstructive pathway earlier. We plan to continue providing this service which has shown to be beneficial clinically and financially.

Outcomes of posterior component separation with transversus abdominis release for repair of abdominally based breast reconstruction donor site hernias

PURPOSE

Abdominally based autologous breast reconstruction (ABABR) is common after mastectomy, but carries a risk of complex abdominal wall hernias. We report experience with posterior component separation (PCS) and transversus abdominis release (TAR) with permanent synthetic mesh repair of ABABR-related hernias.

METHODS

Patients at Cleveland Clinic Foundation and Penn State Health were identified retrospectively. Outcomes included postoperative complications, hernia recurrence, and patient-reported outcomes (PROs): Hernia Recurrence Inventory, HerQLes Summary Score, Patient-Reported Outcome Measurement Information System (PROMIS) Pain Intensity 3a Survey, and the Decision Regret Scale (DRS).

RESULTS

Forty patients underwent PCS/TAR repair of hernias resulting from pedicled (35%), free (5%), muscle-sparing TRAMs (15%), and DIEPs (28%) from August 2014 to March 2021. Following PCS, 30-day complications included superficial surgical site infection (13%), seroma (8%), and superficial wound breakdown (5%). Five patients (20%) developed clinical hernia recurrence. At a minimum of 1 year, 17 (63%) reported a bulge, 12 (44%) reported pain, median HerQLes Quality Of Life Scores improved from 33 to 63/100 (p value < 0.01), PROMIS 3a Pain Intensity Scores improved from 52 to 38 (p value < 0.05), and DRS scores were consistent with low regret (20/100).

CONCLUSION

ABABR-related hernias are complex and technically challenging due to missing abdominal wall components and denervation injury. After repair with PCS/TAR, patients had high rates of recurrence and bulge, but reported improved quality of life and pain and low regret. Surgeons should set realistic expectations regarding postoperative bulge and risk of hernia recurrence.

How to Start and Build a Practice in Microsurgical Breast Reconstruction: Success and Sustainability in a Private Practice Setting

The aim of this article is to provide a template for building and sustaining a microsurgical breast reconstruction practice in a private practice setting. The target audience including residents, microsurgical fellows, and reconstructive microsurgeons were currently employed in an academic setting, and reconstructive microsurgeons were currently employed in a private group entity. We present five pillars that initiate, support, and sustain a successful practice in microsurgical breast reconstruction. The five key concepts are (1) establishing a practice vision and culture, (2) obtaining funding, (3) assembling staff, (4) negotiating insurance and other contracts, and (5) striving for efficiency and sustainability. These concepts have been at the core of Plastic, Reconstructive and Microsurgical Associates of South Texas-a private practice eight-physician group based in San Antonio, Tex.-since its inception. However, these concepts have evolved as the practice has grown and as the economic landscape has changed for reconstructive microsurgeons. In the article, we will present what we have done well, what we could have done better, and some pitfalls to avoid.

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.

Current status of autologous breast reconstruction in Europe: how to reduce donor site morbidity

Autologous reconstruction techniques for breast reconstruction have significantly evolved in the last few decades in Europe. In the search of reducing the donor site morbidity, surgeons explored the possibilities to preserve the rectus muscle and its function, and a transition to deep inferior epigastric perforator (DIEP) flaps was started in the nineties. Throughout the years, and especially in the last decade, we have increasingly implemented aesthetic refinements for donor site handling in DIEP flap breast reconstruction. In our practice, autologous breast reconstruction provides an opportunity to effectively remodel the donor site, minimising functional morbidity, and maximising aesthetic satisfaction. To achieve this, careful patient selection, pre-operative preparation, meticulous intra-operative dissection, and a clear post-operative protocol are essential. The main goal in autologous breast reconstruction, and its biggest advantage, is to offer the patient a natural look and feel of the reconstructed breast. A second goal is to minimize the number of procedures needed to reach the desired breast shape, size, and volume. In most patients, the number of operations ranges between one and three. The third main goal is to minimize the donor site morbidity, both functionally and aesthetically. Functionally, this implies preserving as much of the rectus abdominis muscle as possible, limiting the fascia incision, preserving the motor branches to the muscle, ensuring an adequate fascial closure, and repairing the rectus diastasis is present. Aesthetically, we aim to have a low position of the scar, an aesthetically pleasing location of the umbilicus, and limited or no lateral skin excess or so called "dogears". In this clinical practice review article, we provide an overview of current autologous reconstruction methods, with a focus on minimising donor site morbidity and enhancing the aesthetic result of the donor site. We discuss key concepts in autologous reconstruction and provide surgical pearls for performing the procedure effectively with optimal reconstructive and aesthetic result.

Narrative review of patient-reported outcomes of breast reconstruction

Background and Objective

The treatment of breast cancer encompasses both the elimination of malignancy as well as reconstruction after tumor extirpation. Although the patient may have had successful treatment of her breast cancer, the resulting disfigurement and deformity can have a substantial impact on her physical and mental well-being. Breast reconstruction affords these patients the opportunity to correct these deformities and potentially to improve their quality of life. The current literature review evaluates patient-reported outcomes for the various options of breast reconstruction that are most commonly performed.

Methods

A literature review on PubMed with the key words "patient-reported outcomes", "breast reconstruction", and "breast cancer" yielded 738 results, which were screened. Articles that specifically focused on patient-reported outcomes after various types of breast reconstruction were evaluated and included in this literature review.

Key Content and Findings

The main options of alloplastic reconstruction, autologous tissue reconstruction, and oncoplastic reconstruction were reviewed and found to demonstrate high levels of patient satisfaction. Although there is no clear superior option, patient-reported outcomes demonstrate improved well-being compared to no reconstruction.

Conclusions

Breast reconstruction provides the opportunity to correct the deformities after breast cancer treatment making it a crucial component of comprehensive cancer care. A variety of reconstructive options are available which can be tailored to each individual patient to achieve the optimal results for that particular patient. Therefore patient-reported outcomes are paramount to gauge the true success of not only breast cancer treatment but also reconstructive aspects after treatment.

Patient Preferences for Postmastectomy Breast Reconstruction

Importance

Up to 40% of women experience dissatisfaction after breast reconstruction due to unexpected outcomes that are poorly aligned with personal preferences. Identifying what attributes patients value when considering surgery could improve shared decision-making. Adaptive choice-based conjoint (ACBC) analysis can elicit individual-level treatment preferences.

Objectives

To identify which attributes of breast reconstruction are most important to women considering surgery and to describe how these attributes differ by those who prefer flap vs implant reconstruction.

Design, Setting, and Participants

This web-based, cross-sectional study was conducted from March 1, 2022, to January 31, 2023, at Duke University and between June 1 and December 31, 2022, through the Love Research Army with ACBC analysis. Participants were 105 women at Duke University with a new diagnosis of or genetic predisposition to breast cancer who were considering mastectomy with reconstruction and 301 women with a history of breast cancer or a genetic predisposition as identified through the Love Research Army registry.

Main Outcomes and Measures

Relative importance scores, part-worth utility values, and maximum acceptable risks were estimated.

Results

Overall, 406 women (105 from Duke University [mean (SD) age, 46.3 (10.5) years] and 301 from the Love Research Army registry [mean (SD) age, 59.2 (11.9) years]) participated. The attribute considered most important was the risk of abdominal morbidity (mean [SD] relative importance [RI], 28% [11%]), followed by chance of major complications (RI, 25% [10%]), number of additional operations (RI, 23% [12%]), appearance of the breasts (RI, 13% [12%]), and recovery time (RI, 11% [7%]). Most participants (344 [85%]) preferred implant-based reconstruction; these participants cared most about abdominal morbidity (mean [SD] RI, 30% [11%]), followed by the risk of complications (mean [SD], RI, 26% [11%]) and additional operations (mean [SD] RI, 21% [12%]). In contrast, participants who preferred flap reconstruction cared most about additional operations (mean [SD] RI, 31% [15%]), appearance of the breasts (mean [SD] RI, 27% [16%]), and risk of complications (mean [SD] RI, 18% [6%]). Factors independently associated with choosing flap reconstruction included being married (odds ratio [OR], 2.30 [95% CI, 1.04-5.08]; P = .04) and higher educational level (college education; OR, 2.43 [95% CI, 1.01-5.86]; P = .048), while having an income level of greater than $75 000 was associated with a decreased likelihood of choosing the flap profile (OR, 0.45 [95% CI, 0.21-0.97]; P = .01). Respondents who preferred flap appearance were willing to accept a mean (SD) increase of 14.9% (2.2%) chance of abdominal morbidity (n = 113) or 6.4% (4.8%) chance of complications (n = 115).

Conclusions and Relevance

This study provides information on how women value different aspects of their care when making decisions for breast reconstruction. Future studies should assess how decision aids that elicit individual-level preferences can help tailor patient-physician discussions to focus preoperative counseling on factors that matter most to each patient and ultimately improve patient-centered care.

Influence of Closed-incision Negative Pressure Wound Therapy on Abdominal Site Complications in Autologous Breast Reconstruction

Background

Closed-incision negative pressure wound therapy (ciNPWT) has shown promise in reducing surgical wound complications. Among its numerous benefits, it allows for exudate management and tension offloading from wound edges. The purpose of this systematic review and meta-analysis was to assess the efficacy of prophylactic ciNPWT versus conventional dressings on abdominal donor site complications in microsurgical breast reconstruction (MR).

Methods

A systematic review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines in January 2023. PubMed and Embase were searched to identify all relevant studies. Data collected included rates of total wound complications, wound dehiscence, infection, seroma, and length of hospital stay.

Results

A total of 202 articles were screened, and eight studies (1009 patients) met the inclusion criteria. Use of ciNPWT was associated with a significantly lower rate of wound dehiscence (OR, 0.53; 95% confidence interval, 0.33-0.85; P = 0.0085, I2 = 0%). There was no significant difference in the rate of total wound complications [odds ratio (OR), 0.63; 95% CI, 0.35-1.14; P = 0.12, I2 = 69%], donor site infection (OR, 0.91; 95% CI, 0.42-1.50; P = 0.47, I2 = 13%), seroma (OR, 0.74; 95% CI, 0.22-2.49; P = 0.63, I2 = 57%), or length of hospital stay (SMD, 0.089; 95% CI, -0.13-0.35; P = 0.37, I2 = 29%).

Conclusions

Although exudate management by ciNPWT fails to reduce surgical site infection, seroma formation, and overall length of stay, ciNPWT tension offloading properties seem to be associated with lower rates of wound dehiscence when compared with conventional dressings in abdominal-based autologous breast reconstruction.

A Scoping Review of the Application of BREAST-Q in Surgical Research

Background

Collection of patient-reported outcome (PRO) data can facilitate cost-effective, evidence-based, and patient-centered care. The BREAST-Q has become the gold standard tool to measure PRO data in breast surgery. The last review of its application indicated that it was underutilized. Considering the evolution in breast surgery, the purpose of this study was to perform a scoping review of BREAST-Q application since 2015 and identify emerging trends and potential persistent gaps to guide patient-centered practice and future research in breast surgery.

Methods

We performed an electronic literature review to identify publications published in English that used the BREAST-Q to assess patient outcomes. We excluded validation studies, review papers, conference abstracts, discussions, comments, and/or responses to previously published papers.

Results

We identified 270 studies that met our inclusion criteria. Specific data was extracted to examine the evolution of the BREAST-Q application and examine clinical trends and research gaps.

Discussion

Despite a significant increase in BREAST-Q studies, gaps in the understanding of the patient experience remain. The BREAST-Q is uniquely designed to measure quality of life and satisfaction with outcome and care. The prospective collection of center-specific data for every type of breast surgery will generate important information for the provision of patient-centered and evidence-based care.

Inferior gluteal artery perforator (IGAP) flap in autologous breast reconstruction: A proportional meta-analysis of surgical outcomes

BACKGROUND

The inferior gluteal artery perforator (IGAP) flap is an alternative technique for autologous breast reconstruction. In contrast to other commonly used techniques, there is a paucity of literature on the safety and efficacy of the IGAP flap. The aim of this study was to perform a systematic literature review and meta-analysis of postoperative outcomes and complications associated with the IGAP in autologous breast reconstructions to validate its safety.

METHODS

A systematic review of literature was performed following PRISMA guidelines. Articles reporting post-operative outcomes of IGAP flaps in autologous breast reconstruction were included. A proportional meta-analysis of post-operative complications was performed to obtain their proportions with 95% confidence intervals (CIs).

RESULTS

Seven studies met the inclusion criteria, which represented a total of 239 IGAP flaps in 181 patients The total flap loss rate was 3% (95% CI 0-8%), partial flap loss rate was 2% (95% CI 0-4%), haematoma rate was 3% (95% CI 0-7%), overall donor-site complication rate was 15% (95% CI 5-28%), overall recipient-site complication rate was 24% (95% CI 15-34%), and the overall complication rate was 40% (95% CI 23-58%).

CONCLUSIONS

This meta-analysis provides comprehensive knowledge on the safety and efficacy of the IGAP flap in autologous breast reconstruction. It evidences the IGAP flap in autologous breast reconstruction's overall safety and validates its role as an effective option in breast reconstruction.

[Update and Trends in Breast Reconstruction After Mastectomy]

Due to refinements in operating techniques, autologous breast reconstruction has become part of standard care. It has become more difficult to advise patients due to the expansion of oncologic options for mastectomy, radiation therapy and the variety of reconstructive techniques. The goal of reconstruction is to achieve oncologically clear margins and a long-term aesthetically satisfactory result with a high quality of life. Immediate reconstruction preserves the skin of the breast and its natural form and prevents the psychological trauma associated with mastectomy. However, secondary reconstructions often have a higher satisfaction, since here no restitutio ad integrum is assumed. Alloplastic, i. e., implant-based, breast reconstruction and autologous breast reconstruction are complementary techniques. This article provides an overview of current options for breast reconstruction including patients' satisfaction and quality of life following breast reconstruction. Although immediate reconstruction is still the preferred choice of most patients and surgeons, delayed reconstruction does not appear to compromise clinical or patient-reported outcomes. Recent refinements in surgical techniques and autologous breast reconstruction include stacked-flaps, as well as microsurgical nerve coaptation to restore sensitivity, which lead to improved outcomes and quality of life. Nowadays Skin-sparing and nipple-sparing mastectomy, accompanied by improved implant quality, allows immediate prosthetic breast reconstruction as well as reemergence of the prepectoral implantation. The choice of breast reconstruction depends on the type of mastectomy, necessary radiation, individual risk factors, as well as the patient's habitus and wishes. Overall, recent developments in breast reconstruction led to an increase in patient satisfaction, quality of life and aesthetic outcome with oncological safety.

Trends and issues in clinical research on satisfaction and quality of life after mastectomy and breast reconstruction: a 5-year scoping review

Breast reconstruction (BR) aims to improve the satisfaction and quality of life (QOL) of breast cancer survivors. Clinical studies using patient-reported outcomes (PROs) can therefore provide relevant information to the patients and support decision-making. This scoping review was conducted to analyze recent trends in world regions, methods used, and factors investigated. The literature search was conducted in August 2022. Databases of PubMed, MEDLINE, and CINAHL were searched for relevant English-language studies published from 2017 to 2022. Studies involving women with breast cancer who underwent BR after mastectomy and investigated PROs after BR using BR-specific scales were included. Data on the country, publication year, study design, PRO measures (PROMs) used, time points of surveys, and research themes were collected. In total, 147 articles met the inclusion criteria. BREAST-Q was the most widely used, contributing to the increase in the number and diversification of studies in this area. Such research has been conducted mainly in North America and Europe and is still developing in Asia and other regions. The research themes involved a wide range of clinical and patient factors in addition to surgery, which could be influenced by research methods, time since surgery, and even cultural differences. Recent BR-specific PROMs have led to a worldwide development of research on factors that affect satisfaction and QOL after BR. PRO after BR may be influenced by local cultural and social features, and it would be necessary to accumulate data in each region to draw clinically useful conclusion.

A Safe and Efficient Technique for Pedicled TRAM Flap Breast Reconstruction

LEARNING OBJECTIVES

After studying this article, the participant should be able to: 1. Understand the indications for a unilateral pedicled transverse rectus abdominis (TRAM) flap-based breast reconstruction. 2. Understand the different types and designs of pedicled TRAM flap used in both immediate and delayed breast reconstruction. 3. Understand the essential landmarks and relevant anatomy of the pedicled TRAM flap. 4. Understand the steps of raising the pedicled TRAM flap, the subcutaneous transfer, and the insetting of the flap on the chest wall. 5. Understand the nature of donor-site management and closure of the defect. 6. Develop a postoperative plan for continuing care and pain management.

SUMMARY

This article focuses primarily on the unilateral, ipsilateral pedicled TRAM flap. Although the bilateral pedicled TRAM flap may be a reasonable option in some cases, they have been shown to have a significant impact on abdominal wall strength and integrity. Other types of autogenous flaps using the same lower abdominal tissue, such as a free muscle-sparing TRAM or a deep inferior epigastric flap, can be performed as a bilateral procedure with less impact on the abdominal wall. Breast reconstruction with a pedicled transverse rectus abdominis flap has persisted for decades as a reliable and safe form of autologous breast reconstruction leading to a natural and stable breast shape.

Increased Production of Abdominal Donor Site Fluid Following Microsurgical Breast Reconstruction With Superficial Inferior Epigastric Artery Versus Deep Inferior Epigastric Artery Perforator Flaps

Introduction and aims Donor site seroma following abdominal flap harvest for breast reconstruction is common in both deep inferior epigastric artery perforator (DIEP) and superficial inferior epigastric artery (SIEA) flaps. We tested the hypothesis that there is increased donor site fluid following SIEA dissection compared to DIEP. Materials and methods Of60 SIEA breast reconstructions performed by one surgeon in 50 patients (2004-2019), complete data were available for 31 patients. Eighteen unilateral SIEAs were matched with 18 unilateral DIEPs. Thirteen bilateral flap harvests involving an SIEA were matched with 13 bilateral DIEP controls. Their cumulative abdominal drain outputs, times to drain removal, hospital stay, and number and volume of seroma aspirations were compared. Results Patients who underwent an SIEA flap harvest had significantly increased drain output compared to only a DIEP flap harvest (SIEA=1,078 mL, DIEP=500 mL, p<0.001), which remained significant after controlling for confounding variables (p=0.002). There was increased time until drain removal (SIEA=11 days, DIEP=6 days, p=0.010), and patients who underwent an SIEA harvest were 14 times more likely to be discharged with a drain in situ (odds ratio (OR)=14.6, 95% confidence interval (CI)=2.8203-75.9565, p=0.0014). There was no significant difference in the number or volume of outpatient aspirations, length of hospital admission, or total seroma volume. Conclusion This study demonstrated that SIEA harvest is a significant predictor of increased abdominal drain output postoperatively. This accounted for longer periods before drain removal and more patients discharged with an abdominal drain in situ and should be an important consideration for reconstructive surgeons. There was no demonstrable difference in the number or volume of seroma aspirations after drain removal for either group.

[Satisfaction and quality of life after DIEP-flap breast reconstruction]

Satisfaction and quality of life of patients who have undergone DIEP-flap breast reconstruction have been assessed by many authors in many countries using standardized tools. However, some simple and practical information is often not found in these studies. The aim of our work was to carry out a practical satisfaction survey of patients reconstructed by DIEP flap in our center. Our cohort was made up of 207 patients who underwent DIEP-flap breast reconstruction in Marseille between January 2014 and December 2020. A letter containing our original satisfaction survey was sent to all the patients in our sample. We received 104 responses, which were statistically analyzed using the flat sorting method. Nine-two percent of patients were globally satisfied with the result of their breast reconstruction. A large majority of patients are in favor of the idea of performing their reconstruction again using a DIEP flap. Fifty-five percent of participants were "not bothered at all" by their abdomen after their surgery. The DIEP flap is a versatile technique that allows surgeons to offer it in multiple breast reconstruction situations and to obtain a high degree of patient satisfaction.

Donor-Site Satisfaction of DIEP and Latissimus Dorsi Flaps-A Comparative Cohort Study

BACKGROUND

 Understanding of donor-site morbidity and satisfaction after breast reconstruction is limited. There are few previous studies comparing satisfaction with different donor sites in breast reconstruction. This study aimed to examine the long-term patient-reported satisfaction with the donor site of latissimus dorsi (LD) flaps in comparison to the deep inferior epigastric artery perforator (DIEP) flaps. Further, a systematic review of previously published studies was conducted.

METHODS

 In this retrospective cross-sectional study, all women who underwent breast reconstructions with either LD or DIEP flap following mastectomy and radiotherapy between 2007 and 2017 were included; patient-reported satisfaction was assessed using the BREAST-Q reconstruction module. For the systematic review, studies examining patient-reported abdominal satisfaction and well-being, and meeting the PICO (Population, Intervention, Comparison, and Outcome) criteria were included.

RESULTS

 Eligible and responding participants were divided into the LD (n = 135 patients) and DIEP (n = 118 patients) flap groups. Impairment due to muscular weakness of the donor site was more common in the LD group than that of the DIEP group. Bulging was common in the DIEP group and increased over time. Regarding the esthetic appearance of the donor site, the patients in the DIEP group were less satisfied than the LD group. The systematic review showed that most of the patients were dissatisfied with their abdomen after the operation.

CONCLUSION

 Patients who have undergone DIEP flap for breast reconstruction are less satisfied with the donor-site esthetics than those who have undergone LD flap. Patient-reported abdominal bulging was common in the DIEP group and the number seemed to increase over time. Most patients were not satisfied with their abdominal scarring postoperatively, as per the systematic review. These results may indicate a need for more nuanced preoperative patient information, as well as improvements in the surgical management of the donor site, for DIEP flap reconstructions.

"Closed Incision Negative Pressure Therapy (ciNPT) reduces abdominal donor site surgical wound dehiscence in Deep Internal Epigastric Perforator (DIEP) flap breast reconstructions: DEhiscence PREvention Study II (DEPRES II) - a Randomized Clinical Trial"

BACKGROUND

In breast reconstruction surgeries, surgical wound dehiscence is a serious complication which generates a significant burden on patients and healthcare systems. There are indications that postoperative treatment with closed incision negative pressure therapy (ciNPT) has been associated with reduced wound dehiscence rates. This randomized clinical trial examines the effect of ciNPT application on abdominal donor site surgical wound dehiscence in low- and high-risk patients undergoing a breast reconstruction with a deep internal epigastric perforator (DIEP) flap.

METHODS

Eighty eligible women, stratified as low- or high-risk patients, were included and were randomized for treatment with either ciNPT or adhesive strips (AS) by drawing sealed, opaque envelopes. All surgeons were kept blind for allocation. Primary outcomes were surgical wound dehiscence and surgical site infection at the abdominal donor site upon follow-up after 12 weeks. Secondary outcomes were seroma and hematoma formation. Five patients were excluded from the study due to non-sufficient exposure to the study treatment (n=4) or major protocol deviation (n=1).

RESULTS

A total of 75 women, low-risk (n=38) and high-risk (n=37), received either ciNPT (n=36) or AS (n=39). Patients' demographics did not differ significantly. Donor-site surgical wound dehiscence occurred in 23 patients; the Absolute Risk Reduction was statistically significant (21.6%, 95% Confidence Interval [1.5-41.7]). No statistically significant differences were found in surgical site infection or secondary outcomes.

CONCLUSIONS

In this randomized clinical trial, postoperative treatment with ciNPT decreased the incidence of surgical wound dehiscence at the abdominal donor site in low- and high-risk DIEP flap breast reconstruction patients.

[Change of Gaze Pattern depending on the Stage of DIEP Flap Breast Reconstruction: a Preliminary Eye-Tracking Investigation]

BACKGROUND

Breast reconstruction using autologous tissue is an integral part of breast cancer treatment. While many studies have elucidated the impact of breast reconstruction on patients' quality of life, self-esteem, sexuality and more, there is a lack of objective data regarding the effects on external observers. Aim of this study was to investigate the change in gaze pattern of independent observers depending on the stage of DIEP-flap breast reconstruction.

MATERIALS AND METHODS

Eye-tracking technology was utilized to analyze the eye movements of 58 study participants while viewing 2 D photographs of a patient after mastectomy and different stages of DIEP-flap breast reconstruction. Time until first fixation and total time of fixation were recorded and con- secutively analyzed for the right and left breast on each image.

RESULTS

Overall, the total time of fixation of the operated breast decreased significantly over the different stages of breast reconstruction, with p<0.001. At the same time, there was no statistically significant change in total time of fixation of the non-operated breast, with p=0.174. The time until first fixation showed a significant increase over the different stages of reconstruction for the reconstructed breast, with p<0.001, while no significant differences were found for the opposite breast, with p=0.344.

CONCLUSION

Mastectomy and the individual steps of breast reconstruction alter the perception of breast cancer patients. Over the course of breast reconstruction, the deviation of gaze in the direction of the affected breast is reversed.

Comparison of short-term outcomes between pedicled- and free-flap autologous breast reconstruction: a nationwide inpatient database study in Japan

BACKGROUND

Despite the increasing popularity of autologous breast reconstruction, limited evidence is available. The aim of the present study was to compare the short-term outcomes of pedicled- and free-flap breast reconstructions.

METHODS

Using a nationwide Japanese inpatient database, we identified 13,838 patients who underwent breast reconstruction for breast cancer (July 2010-March 2020) using a pedicled or free-flap (pedicled- and free-flap groups, n = 8279 and 5559, respectively). One-to-one propensity score matching was performed to compare the occurrence of postoperative complications, duration of anesthesia, length of stay, and total costs between the two groups. We also performed subgroup analyses stratified by hospital volume.

RESULTS

The propensity score-matched analysis involving 3524 pairs showed that the pedicled-flap group had significantly lower proportions of takeback (2.1% vs. 3.2%, p < 0.001), thrombosis (0.6% vs. 1.7%, p < 0.001), and postoperative bleeding (2.1% vs. 5.7%, p < 0.001) than the free-flap group. No significant differences were found in wound dehiscence or tissue necrosis. Compared to the free-flap group, the pedicled-flap group had a short duration of anesthesia (412 vs. 647 min, p < 0.001) and low total hospitalization costs (12 662 vs. 17 247 US dollars, p < 0.001) but a prolonged postoperative length of stay (13 vs. 12 days, p < 0.001). The subgroup analyses showed results compatible with those of the main analysis.

CONCLUSIONS

In this large nationwide cohort of patients who underwent breast reconstruction, pedicled-flap reconstruction was associated with fewer postoperative complications (excluding necrosis and wound dehiscence) and lower hospitalization costs but a longer postoperative length of stay than free-flap reconstruction.

Morbidity of the Donor Site and Complication Rates of Breast Reconstruction with Autologous Abdominal Flaps: A Systematic Review and Meta-Analysis

Background. Numerous studies have evaluated the use of autologous abdominal tissue for breast reconstruction; nevertheless, complications and donor site morbidity rates vary significantly. The study aims to compare the literature regarding morbidity of the donor site and complication rates of breast reconstruction with autologous abdominal flaps. Methods. The databases of MEDLINE, EBSCO, Scopus, Wiley Library, and Web of Sciences were searched for studies that compared different flaps in terms of complications and donor site morbidity. The procedures studied included pedicled transverse rectus abdominis myocutaneous flap (pTRAM), free TRAM (fTRAM), deep inferior epigastric perforator (DIEP), and superficial inferior epigastric artery perforator (SIEA) flaps. A total of 34 studies were included. Of these, 28 were retrospective studies and 9 were prospective cohort studies. Results. When compared to DIEP, fTRAM flaps were found to have a decreased incidence of flap fat necrosis, hematoma, and total thrombotic events, yet a higher risk of donor site hernia/bulging. pTRAM flaps were also associated with an increased risk of hernia/bulging at the donor site, as well as wound infection, yet flap hematoma was less common. On the other hand, SIEA flaps showed the lowest risk of donor site hernia/bulging while still having a high risk of wound infection. Conclusion. fTRAM procedures comparatively had the least complications. However, regarding flap choice, patients would benefit most from a case-by-case analysis, taking into consideration individual risk factors and preferences.

Identifying breast cancer recurrence histories via patient-reported outcomes

PURPOSE

To test accuracy of patient self-report of breast cancer recurrence for enhancing standard population-based cancer registries that do not routinely collect cancer recurrence data despite the importance of this outcome.

METHODS

Potential research subjects were identified in the Breast Cancer Research Database (BCRD) of the Swedish Cancer Institute (SCI). The BCRD has collected data within 45 days of each medical encounter on new primary breast cancer patients receiving all or part of their initial care at SCI. Females diagnosed with a new primary breast cancer 2004-2016, Stages I-III, and alive at the time of study initiation (2018) were identified. Recurrent breast cancer patients were matched 1:1 to surviving non-recurrent patients by patient age, date of diagnosis, and single or multiple primary tumors. Consented research subjects were surveyed about their initial and subsequent diagnostic, therapeutic, and recurrent events. PRO survey responses were compared with BCRD information for each individual participant. Discrepancies were reviewed in medical records.

RESULTS

A matched sample of 88 recurrent and 88 non-recurrent patients were used in analyses. Respondents correctly identified the date of diagnosis of first primary breast cancer within 1 year 94% (165/176). Recurrence was reported by 97% (85/88) of recurrent patients. No recurrence was reported by 100% (88/88) of non-recurrent patients. Recurrence date within 1 year was correctly identified in 79% (67/85). Recurrence site was correctly identified in 82% (70/85). Medical record review of survey-registry discrepancies led to BCRD corrections in 4.5% (8/176) of cases.

IMPLICATIONS FOR CANCER SURVIVORS

Breast cancer patients can accurately report their disease characteristics, treatments, and recurrence history. Patient-reported information would enhance cancer registry data.

Safety of DIEP Flap Reconstruction in Patients with Factor V Leiden: A Retrospective Cohort Study

Background:

Factor V Leiden (FVL) is the most common inherited thrombophilia in White people. Thrombotic complications resulting from free flap breast reconstruction in FVL patients have been studied to a limited degree. We evaluated whether patients heterozygous for a FVL mutation undergoing deep inferior epigastric perforator flap reconstruction had increased risk of micro- or macrovascular thrombotic complications compared with patients without a diagnosed thrombophilia.

Methods:

We performed a retrospective cohort study of deep inferior epigastric perforator flap reconstructions at Brigham and Women’s Hospital (1/2015–12/2020) comparing patients diagnosed as FVL heterozygotes compared with matched controls without a diagnosed thrombophilia. Patients were matched using coarsened exact matching algorithm based on clinical characteristics. The primary outcomes were micro- (return to OR for flap compromise, flap loss) and macrovascular (venous thromboembolism) complications.

Results:

A total of 506 patients (812 flaps) were included in this study. Eleven patients (17 flaps) were FVL heterozygotes. After matching, 10 patients (16 flaps) with FVL were matched to 55 patients (94 flaps). The return to OR for flap compromise was 0% in the FVL cohort compared with 5% (n = 5/94, 3/94 flaps lost, P = 1.00) in the matched controls (1.9%, n = 15/795 in unmatched controls, 0.6%, n = 5/795 loss rate). There were zero venous thromboembolism events among FVL patients compared with 2% of controls (n = 1/55).

Conclusions:

FVL heterozygosity did not increase the risk of micro- or macrovascular complications in patients undergoing deep inferior epigastric perforator flap breast reconstruction. This study supports the safety of microvascular reconstruction in this group of patients when appropriate venous thromboembolism prophylaxis is given.

Prevention of Abdominal Bulging Using Onlay Dermal Autografts from Discarded Zone IV TRAM Flap Tissue

While the transverse rectus abdominis myocutaneous (TRAM) flap is a popular option for abdominal-based breast reconstruction, abdominal wall morbidities such as bulging or hernia remain a concern. Here, we introduced a surgical technique for reinforcing the abdominal wall using an onlay autograft obtained from discarded zone IV tissue following a primary closure. We compared abdominal wall morbidities between patients receiving an onlay graft and those receiving primary closure only. We retrospectively reviewed the medical charts of patients who underwent breast reconstruction using a TRAM flap between December 2018 and May 2021. Additionally, we assessed donor-site morbidities based on physical examination. Of the 79 patients included, 38 had received a dermal graft and 41 had not. Donor-site morbidities occurred in 10 (24.5%) and 1 (2.6%) patients, and bulging occurred in 8 (19.5%) and 1 (2.6%) patients in the primary closure and dermal autograft groups, respectively. A statistically significant difference in the incidence of bulging was observed between the groups (p = 0.030). In conclusion, the introduction of a dermal autograft after primary closure can successfully ameliorate morbidities at the TRAM flap site.

Autologous Reconstruction after Mastectomy for Breast Cancer

Background

Women undergoing autologous reconstruction (AR) after mastectomy for breast cancer and their surgeons must make decisions regarding timing of the AR and choose among various flap types. We conducted a systematic review to evaluate the comparative benefits and harms of (1) timing of AR relative to chemotherapy and radiation therapy, and (2) various flap types for AR.

Methods

We searched Medline, Embase, Cochrane CENTRAL, CINAHL, and ClinicalTrials.gov for studies, from inception to March 23, 2021, without language restriction. We assessed risk of bias of individual studies and strength of evidence (SoE) of our findings using standard methods.

Results

We screened 15,936 citations. Twelve mostly high risk of bias studies, including three randomized controlled trials and nine nonrandomized comparative studies met criteria (total N = 31,833 patients). No studies addressed timing of AR relative to chemotherapy or radiation therapy. Six flap types were compared, but conclusions were feasible for only the comparison between transverse rectus abdominus myocutaneous (TRAM) and deep inferior epigastric perforator (DIEP) flaps. The choice of either flap may result in comparable patient satisfaction with breasts and comparable risk of necrosis (low SoE for both outcomes), but TRAM flaps probably pose a greater risk of harm to the area of flap harvest (abdominal bulge/hernia and need for surgical repair) (moderate SoE).

Conclusions

Evidence regarding details for AR is mostly of low SoE. New high-quality research among diverse populations of women is needed for the issue of timing of AR and for comparisons among flap types.

Teaching Microsurgical Breast Reconstruction-A Retrospective Cohort Study

Microsurgical breast reconstruction demands the highest level of expertise in both reconstructive and aesthetic plastic surgery. Implementation of such a complex surgical procedure is generally associated with a learning curve defined by higher complication rates at the beginning. The aim of this study was to present an approach for teaching deep inferior epigastric artery perforator (DIEP) and transverse upper gracilis (TUG) flap breast reconstruction, which can diminish complications and provide satisfying outcomes from the beginning. DIEP and TUG flap procedures for breast reconstruction were either performed by a senior surgeon (>200 DIEP/TUG, "no-training&nbsp;group"), or taught to one of five trainees (>80 breast surgeries; >50 free flaps) in a step-wise approach. The latter were either performed by the senior surgeon, and a trainee was assisting the surgery ("passive training"); by the trainee, and a senior surgeon was supervising ("active training"); or by the trainee without a senior surgeon ("after training"). Surgeries of each group were analyzed regarding OR-time, complications, and refinement procedures. A total of 95 DIEP and 93 TUG flaps were included into this study. Before the first DIEP/TUG flap without supervision, each trainee underwent a mean of 6.8 DIEP and 7.3 TUG training surgeries (p > 0.05). Outcome measures did not reveal any statistically significant differences (passive training/active training/after training/no-training: OR-time (min): DIEP: 331/351/338/304 (p > 0.05); TUG: 229/214/239/217 (p > 0.05); complications (n): DIEP: 6/13/16/11 (p > 0.05); TUG: 6/19/23/11 (p > 0.05); refinement procedures (n): DIEP:71/63/49/44 (p > 0.05); TUG: 65/41/36/56 (p > 0.05)), indicating safe and secure implementation of this step-wise training approach for microsurgical breast reconstruction in both aesthetic and reconstructive measures. Of note, despite being a perforator flap, DIEP flap required no more training than TUG flap, highlighting the importance of flap inset at the recipient site.

Use of Closed Incision Negative Pressure Therapy (ciNPT) in Breast Reconstruction Abdominal Free Flap Donor Sites

BACKGROUND

Closed incision negative pressure therapy (ciNPT) may reduce the rate of wound complications and promote healing of the incisional site. We report our experience with this dressing in breast reconstruction patients with abdominal free flap donor sites.

METHODS

A retrospective cohort study was conducted of all patients who underwent breast reconstruction using abdominal free flaps (DIEP, MS-TRAM) at a single institution (Royal Melbourne Hospital, Victoria) between 2016 and 2021.

RESULTS

126 female patients (mean age: 50 ± 10 years) were analysed, with 41 and 85 patients in the ciNPT (Prevena) and non-ciNPT (Comfeel) groups, respectively. There were reduced wound complications in almost all outcomes measured in the ciNPT group compared with the non-ciNPT group; however, none reached statistical significance. The ciNPT group demonstrated a lower prevalence of surgical site infections (9.8% vs. 11.8%), wound dehiscence (4.9% vs. 12.9%), wound necrosis (0% vs. 2.4%), and major complication requiring readmission (2.4% vs. 7.1%).

CONCLUSION

The use of ciNPT for abdominal donor sites in breast reconstruction patients with risk factors for poor wound healing may reduce wound complications compared with standard adhesive dressings; however, large scale, randomised controlled trials are needed to confirm these observations. Investigation of the impact of ciNPT patients in comparison with conventional dressings, in cohorts with equivocal risk profiles, remains a focus for future research.

The Goldilocks Procedure with and without Implant-Based Immediate Breast Reconstruction in Obese Patients: The Mayo Clinic Experience

BACKGROUND

Obesity is a risk factor for complications in breast reconstruction. Thus, implant-based immediate breast reconstruction in obese women may be controversial. The authors analyzed obese patients who underwent skin-sparing mastectomy using Wise-pattern incisions (Goldilocks procedure) and compared outcomes between two groups: Goldilocks with immediate breast reconstruction and Goldilocks only.

METHODS

A retrospective review was performed of patients with a body mass index of 30 kg/m2 or higher who underwent the Goldilocks procedure at the Mayo Clinic Health System from 2012 to 2019. Data were extracted from electronic medical records. Minor complications (partial-thickness wound dehiscence or flap necrosis, or tissue expander/implant malposition) and major complications (full-thickness wound dehiscence or flap necrosis, capsular contracture, tissue expander/implant explantation, or unplanned reoperation or readmission) were compared between groups. Patient-reported outcomes using BREAST-Q questionnaires were also assessed.

RESULTS

One hundred five patients (181 breasts) were included. Mean ± SEM age and body mass index were 57.1 ± 10.4 years and 37.9 ± 5.8 kg/m2 for the Goldilocks-only group and 51.5 ± 1.1 years and 35.5 ± 0.4 kg/m2 for the Goldilocks with immediate breast reconstruction group, respectively. Median follow-up time was 15.1 months (interquartile range, 10.0 to 28.6 months). Overall, 96 breasts underwent the Goldilocks-only procedure and 85 Goldilocks with immediate breast reconstruction. Multivariable analyses revealed a higher rate of minor complications (adjusted hazard ratio, 2.83; 95 percent CI, 1.22 to 7.02) and major complications (adjusted hazard ratio, 2.26; 95 percent CI, 1.25 to 4.24) in the Goldilocks with immediate breast reconstruction group compared with the Goldilocks-only group, at any given time. Patient satisfaction was not statistically different between groups.

CONCLUSIONS

The Goldilocks procedure is a feasible breast reconstructive option in obese patients; however, when it is performed with immediate breast reconstruction, it is associated with higher rates of complications. For patients with a body mass index of 40 kg/m2 or greater, the authors recommend the Goldilocks-only procedure or delayed reconstruction.

Modified Frailty Index (mFI) predicts 30-day complications after microsurgical breast reconstruction

Frailty lacks a universal definition. The modified Frailty Index (mFI) using patient comorbidities can be used to measure frailty. We hypothesized that mFI predicts 30-day complications after microsurgical breast reconstruction. American College of Surgeons' (ACS) National Surgical Quality Improvement Project (NSQIP) was investigated to identify patients undergoing microsurgical breast reconstruction between 2005-2014 using Current Procedure Terminology (CPT) code, 19364. We used mFI as a measure of frailty. The patients were assigned a frailty score based on the number of preoperative comorbid conditions as defined by the mFI. Other risk indices used include age, BMI, wound class, ASA class. Stratification was performed in ascending order for each. The outcome measure was aggregate 30-day complications. Regression analysis was performed followed by Receptor Operating Characteristic (ROC) curve to determine the accuracy of each risk index in predicting 30-day complications. Of the 3237 patients 24% experienced complications. Univariate logistic regression analysis found odds ratio of complications for frailty score 1 = 22.1 (CI = 17.9-27.3, p < 0.01), and 2 = 28 (CI = 18.3-43, p < 0.01) compared to frailty score = 0. ROC curve demonstrated mFI with the highest concordance score (c-score = 0.816). Multivariable logistic regression found frailty as the strongest independent predictor of 30-day aggregate complications adjusted OR = 22.24, CI = 17.77-27.82, p < 0.01 when compared to other risk indices. The modified Frailty Index is a simple, reliable, and objective tool that can be used to predict postoperative complications after microsurgical breast reconstruction. The application of this tool can help microsurgeons preoperatively identify patients who are at high risk.Abbreviations: ACS: American College of Surgeons; ASA: American Society of Anesthesiologists; BMI: body mass index; CHF: congestive heart failure; CPT: current procedural terminology; COPD: chronic obstructive pulmonary disease; CVA: cerebrovascular accident; DM: diabetes mellitus; IRB: institutional review board; mfi: modified frailty index; MI: myocardial infarction; NSQIP: national surgical quality improvement program; PVD: peripheral vascular disease; ROC: receptor operating characteristic; TIA: transient ischemic attach.

Safety of a Modified Lipoabdominoplasty Technique for Donor-Site Closure in Abdominal-Based Free Flap Breast Reconstruction

BACKGROUND

The aesthetic and functional outcomes of the donor site following abdominal-based free flap breast reconstruction have been suboptimal. The objective of this study is to evaluate a modified liposuction-assisted abdominoplasty technique combined with rectus plication (LPARSP) adopted from cosmetic abdominoplasty practice.

PATIENTS AND METHODS

All abdominal-based free flap breast reconstructions from 01/2017 to 03/2019 were reviewed. Patients with central fullness and sufficient tissue surplus on the abdomen, thighs and flanks who received LPARSP and rectus plication were identified (LPARSP group) and matched for age and body mass index with patients who underwent conventional abdominoplasty (CA group). Abdominal skin sensation, objective functional and aesthetic measures of the abdomen, as well as patient-reported outcomes (Breast-Q), were analyzed.

RESULTS

A total of 28 patients were included. Groups were similar in demographics. The mean amount of lipoaspirate in the LPARSP group was 1054±613.5 ml. The postoperative course was similar in both groups. The LPARSP technique resulted in a lower positioned horizontal scar (p = 0.03). The aesthetic outcome was superior in the LPARSP group (p < 0.0001). Furthermore, the LPARSP group presented with a decreased bulging rate (p = 0.05), and secondary refinement procedures were less frequently demanded (p = 0.02). In addition, the abdominal wall sensation of the flanks was improved in the LPARSP group (p = 0.05), whereby patient-reported outcome measures did not differ between groups.

CONCLUSIONS

Lipoabdominoplasty with rectus plication represents a safe approach for donor-site closure in selected patients undergoing abdominal-based free flap breast reconstruction. Superior functional and aesthetic results paired with improved abdominal wall sensation are achieved compared to CA.

Deep inferior epigastric perforator free flap in elderly women for breast reconstruction: The experience of a tertiary referral center and a literature review

BACKGROUND

A general belief is to consider elderly patients as poor candidates for free flap reconstruction, which does not reflect our 20-year experience for breast reconstruction (BR). The aim of this study was to determine the safety and benefits of BR using deep inferior epigastric perforator (DIEP) free flap in the elderly population.

METHODS

We conducted a retrospective study of all consecutive BRs using DIEP flaps in patients 65 years or older at the European Georges Pompidou Hospital from January 2011 to December 2019. Postoperative complications were reported as minor or major. We used a descriptive approach to analyze the main characteristics of the patients included. Surgical patient-reported outcomes and quality of life were assessed using the validated BREAST-Q questionnaire.

RESULTS

Eighty-three DIEP flaps were performed in 79 patients (4 bilateral flaps) for BR. Sixty-six percent of the patients (52/79) did not present any complication. Total flap loss occurred in 3 BR (3.6%), arterial thrombosis in 4 BR (4.8%), and venous thrombosis in 8 BR (9.6%). The average duration of inpatient stay was 9.5 (±2.7) days. Forty-one of 69 eligible patients completed the questionnaire (response rate 59.4%). Patients reported high satisfaction and well-being scores. The mean Q score for psychosocial well-being was 75.4 (±16.7) and 59 (±13.3) for satisfaction with breasts.

CONCLUSION

In our retrospective cohort, DIEP flap BR in elderly population had similar success and complication rates compared with those in younger patients, as well as high satisfaction scores. The free flap should be encouraged for BR in women over 65 years of age, and personal motivation as well as physiological age considered as main criteria for patient selection.

Incisional Hernia Incidence, Repair Techniques, and Outcomes Based on 1600 Consecutive Patients Receiving Abdominally Based Autologous Breast Reconstruction

BACKGROUND

As the number of postmastectomy patients who receive abdominally based autologous breast reconstruction (ABABR) increases, the frequency of unique paramedian incisional hernias (IHs) at the donor site is increasing as well. We assessed incidence, repair techniques, and outcomes to determine the optimal treatment for this morbid condition.

METHODS

A total of 1600 consecutive patients who underwent ABABR at the University of Pennsylvania between January 1, 2009, and August 31, 2016, were retrospectively identified. Preoperative and operative information was collected for these patients. Incisional hernia incidence was determined by flap type and donor site closure technique. Repair techniques and postoperative outcomes for all patients receiving IH repair (IHR) after ABABR at our institution were also determined. Univariate and multivariate analyses were conducted.

RESULTS

The incidence of IH after ABABR in our health system was 3.6% (n = 61). Fifteen additional patients were referred from outside hospitals for a total of 76 patients who received IHR. At the time of IHR, mesh was used in 79% (n = 60) of cases (13 biologic and 47 synthetic), with synthetics having significantly lower recurrent IH incidence (10.6% vs 38.5%, P = 0.017) when compared with biologics. Mesh position did not have any statistically significant effect on outcomes; however, sublay mesh position had zero adverse outcomes.

CONCLUSIONS

Mesh should be used in all cases when possible. Although retrorectus repair with mesh is optimal, this plane is often nonexistent or too scarred in after ABABR. Thus, intraperitoneal underlay mesh with primary fascial closure or primary closure with onlay mesh placement should then be considered.

The Use of Semi-Absorbable Mesh and its Impact on Donor-Site Morbidity and Patient-Reported Outcomes in DIEP Flap Breast Reconstruction

BACKGROUND

This study aimed to evaluate the impact of semi-absorbable mesh on donor-site morbidity and patient-reported outcomes in deep inferior epigastric perforator (DIEP) flap breast reconstruction.

METHODS

We conducted a retrospective cohort study of all patients who had DIEP flap breast reconstruction in our department from July 2007 to March 2019. Patients were invited to a comparative follow-up visit and grouped according to donor-site closure: primary fascial closure (the no-mesh group) and fascial reinforcement with semi-absorbable mesh in a subfascial position (the mesh group). The primary outcome of interest was donor-site morbidity, including bulging, hernia formation and rectus abdominis muscle strength. We also surveyed, surgical site complications and patient-reported outcomes using Patient and Observer Scar Assessment Scale v2.0 and BREAST-Q^© version 2.0.

RESULTS

A total of 191 patients had received DIEP flap breast reconstruction. Eighty-five patients (44.5%) with 108 DIEP flaps (53 patients in the mesh group and 32 patients in the no-mesh group) were included in the study. The mean BMI of the patients was significantly higher in the mesh group (mesh group, 26.9 vs. no-mesh group, 25.0, with p = 0.03). The incidence of hernia was significantly reduced in the mesh group (mesh group, 2.8% vs. no-mesh group, 13.5%, with p = 0.03). The incidence of bulging and the extent of rectus abdominis muscle strength were similar for both groups. Operative surgical site complications were reduced in the mesh group (mesh group, 7.5% vs. no-mesh group, 18.8%). There was no difference in patients' physical well-being and satisfaction with the donor site between groups. Patient-reported scar outcome was significantly better in the no-mesh group (p < 0.001).

CONCLUSION

Our novel method of donor-site closure with semi-absorbable mesh in a subfascial position for reinforcement of the anterior rectus fascia on the DIEP donor site is safe. It has no negative impact on surgical site complications and patient-reported outcomes, while reducing the incidence of hernias on the donor-site in DIEP flap breast reconstruction.

Overall Complication Rates of DIEP Flap Breast Reconstructions in Germany-A Multi-Center Analysis Based on the DGPRÄC Prospective National Online Registry for Microsurgical Breast Reconstructions

While autologous breast reconstruction has gained momentum over recent years, there is limited data on the structure and quality of care of microsurgical breast reconstruction in Germany. Using the breast reconstruction database established by the German Society of Plastic, Reconstructive and Aesthetic Surgeons (DGPRÄC), the presented study investigated the overall outcomes of deep inferior epigastric perforator (DIEP) flap reconstructions in Germany. Data of 3926 patients and 4577 DIEP flaps performed by 22 centers were included in this study. Demographics, patient characteristics, perioperative details and postoperative outcomes were accounted for. Centers performing < Ø 40 (low-volume (LV)) vs. ≥ Ø 40 (high-volume (HV)) annual DIEP flaps were analyzed separately. Overall, total and partial flap loss rates were as low as 2.0% and 1.1% respectively, and emergent vascular revision surgery was performed in 4.3% of cases. Revision surgery due to wound complications was conducted in 8.3% of all cases. Mean operative time and length of hospital stay was significantly shorter in the HV group (LV: 385.82 min vs. HV: 287.14 min; LV: 9.04 (18.87) days vs. HV: 8.21 (5.04) days; both p < 0.05). The outcome and complication rates deduced from the national registry underline the high standard of microsurgical breast reconstruction on a national level in Germany.

Can pedicled TRAM flap be a satisfying alternative to free TRAM in developing countries? - a systematic review and meta-analysis

BACKGROUND

Breast reconstruction can ease the psychological burden in breast cancer patients that have undergone mastectomy. The aim of our study is to collect the latest evidences to summarize whether pedicled TRAM (pTRAM) is non-inferior in terms of patient satisfaction and complications to free TRAM (fTRAM) so that it may be used in region with limited resources.

METHODS

We performed a comprehensive search on studies that compared pTRAM and fTRAM flap from several databases.

RESULTS

There are six studies included. Despite the diversity among the correspondents, all studies demonstrated no difference between the two groups regarding patient overall satisfaction. However, two studies found that pTRAM had lower abdominal well-being score, three found higher abdominal related morbidity, while fTRAM had a higher overall cost. Pooled mean difference was not significant on all BREAST-Q subscales, meaning that pTRAM and fTRAM has a similar outcome.

CONCLUSION

Although pTRAM is non-inferior in terms of satisfaction to fTRAM, it is associated with a more frequent complication. It may be used in developing countries that lack facilities and limited by cost. However, pTRAM should be done by experienced surgeons to minimize the risk of complications.

Complications and Patient-reported Outcomes after TRAM and DIEP Flaps: A Systematic Review and Meta-analysis

Supplemental Digital Content is available in the text.

Transverse rectus abdominis myocutaneous (TRAM) and deep inferior epigastric artery perforator (DIEP) flaps are the most common abdominally based breast reconstruction procedures. Each technique has its advantages and disadvantages; however, how morbidity relates to satisfaction is not well-understood. Our aim was to compare complications and patient-reported outcomes following pedicled TRAM (pTRAM), free TRAM (fTRAM), and DIEP flaps to guide flap selection.

An Idea of Hemi-abdominal Free Flap for Breast Reconstruction: A Case Report

A deep inferior epigastric perforator (DIEP) flap is one of the gold standards for autologous breast reconstructions. However, this flap cannot be chosen again if asynchronous contralateral breast cancer occurs in the future. To solve this problem, we propose an idea and design for a hemi-abdominal DIEP flap. The patient was a 50-year-old woman who was suffering from right invasive ductal carcinoma. In using a hemi-abdominal DIEP flap, the poor postoperative appearance of the donor site might be a problem. To obtain a good donor site shape, we use a specific design to make the appearance of the donor site as good as possible. Specifically, we make an oblique spindle-shaped flap that can cover the deep inferior epigastric perforators, the superficial circumflex iliac artery, and the superficial inferior epigastric artery and avoid dog-ears, without passing over the median line. The flap weight was 800 g, the operating time was 6 hours and 22 minutes, and the bleeding amount was 110 ml. The patient had a minor wound infection in the donor site, and it was treated with a local wound treatment. The patient is satisfied with the result. We believe our flap design could minimize the unfavorable appearance of the donor site. This method might be suited to cases where the patients present with excess skin and fat on the abdomen, and half the abdominal tissue is enough to create the necessary volume of the breast. Although more cases and studies will be required to justify our technique, this case may show the possibility of a new option for breast reconstructions.
