Abstract
BACKGROUND Abdominal-based perforator flaps are the gold standard for autologous breast reconstruction. However, among patients with a small-to-medium amount of redundant abdominal tissue, this may result in an inadequate breast mound. Secondary implant augmentation has been reported as one method to augment volume, address breast mound asymmetry, and enhance overall aesthetic outcome. We aim to analyze postoperative complications associated with the secondary implant augmentation following a primary breast reconstruction with abdominal perforator flaps. METHODS This retrospective study included patients who underwent secondary implant augmentation following abdominal-based perforator flap breast reconstruction. Patient characteristics, immediate versus delayed reconstruction, type of flap used, indication for secondary augmentation as well as perioperative and postoperative complication including flap or implant loss were reviewed and analyzed. RESULTS Twenty-four patients met inclusion criteria. Forty flaps were performed (16 bilateral and 8 unilateral). A total of 36 implants were placed in subpectoral plane in a secondary revision procedure. The mean time between secondary augmentation and index procedure was 22 months. Average implant volume was 270 g. No intraoperative complication or flap loss was recorded. Postoperative surgical site infection occurred in a total of 4 patients (17%) with 3 patients requiring explantation of a total of 4 implants. CONCLUSIONS Secondary augmentation of abdominal-based perforator flap using a permanent implant is an effective method to address volume and asymmetry and to enhance aesthetic outcome. In our study, however, we observed a higher than expected rate of postoperative infection.

Abstract
Introduction: Breast surgery complications are important not only due to their morbidity and psychological impact, but also the delays that can occur for adjuvant treatment or the loss of implants in severe cases. There is growing evidence that negative pressure dressing on closed wounds can reduce the complications following surgery. Methods: This study aimed to assess whether negative-pressure dressings reduced complications in patients undergoing bilateral reduction mammoplasty with randomization of a side to negative pressure and standard care, fixation strips, on the contralateral side. This allowed patients to act as their own controls. Results: This study found a significant reduction in the rate of wound complications but used a wide definition for what constituted a wound complication. Discussion: This finding is mirrored in existing work with studies showing that negative-pressure therapy is a cost-effective intervention. Further work is required to validate this finding and targeting those at highest risk may be preferential.

Abstract
BACKGROUND This study compared the outcomes of unilateral microsurgical breast reconstructions using abdomen-based flaps between normal body mass index (BMI; 18.5 < BMI < 24.9 kg/m2) and overweight (25 < BMI < 29.9 kg/m2) patients. METHODS Between March 2000 and December 2015, patients who underwent unilateral breast reconstructions using abdomen-based flaps were retrospectively evaluated. Outcomes variables evaluated included the flap-used weight, flap-used/flap-harvested percentage, flap-used/specimen percentage, complication rates, revision procedures, and quality of life using the Breast-Q questionnaires. RESULTS A total of 415 patients with a mean age of 45.3 ± 8.2 years underwent 418 abdomen-based flaps. The overall success rate was 98.8%, with 99.1% and 97.9% of patients included in the normal BMI and overweight groups, respectively (p = 0.36). The mean flap-used weight and flap-used/flap-harvested values of 461 ± 132.1 g and 82.2 ± 11.6%, respectively, in the normal BMI group were statistically different from values of 610 ± 148.9 g and 71.4 ± 14.1% in the overweight group (both p < 0.01). The mean flap-used/specimen percentage was 118.5 ± 32.9 and 111.7 ± 36.6 in the normal BMI and overweight groups, respectively (p = 0.26). At a mean follow-up of 135 ± 55.4 months, there were no statistical differences between the two groups in terms of total complication rates (25.7% vs. 29.2%; p = 0.30), revision times (36.1% vs. 36.5%; p = 0.91) and all four domains (all p > 0.05) of the Breast-Q. CONCLUSIONS Patients with a normal BMI required a smaller flap-used weight but higher flap-used/flap-harvested percentage for unilateral microsurgical breast reconstructions that could be performed with a high success rate and comparable complication and revision rates.

Abstract
BACKGROUND Autologous reconstruction after mastectomy became more and more popular, so this study aimed to obtain up-to-date and comprehensive data on autologous reconstruction in China. METHODS An electronic questionnaire was sent to 110 hospitals, which were chosen depending on geographical distribution and hospital types. The questionnaire investigated the demographics, characteristics, breast cancer treatment and reconstruction situation of these hospitals through different modules. We only focused on the autologous breast reconstruction module data. RESULTS 96 hospitals have performed breast reconstruction surgery. The proportion of the hospital performing latissimus dorsi flap (LDF, N = 91), pedicle transverse rectus abdominis myocutaneous flap (pTRAM, N = 62), free abdominal flap (N = 43) and other kinds of flap decreased in sequence. Of the overall reconstruction cases, only 34.3% were autologous reconstruction and LDF was still the most popular option for autologous reconstruction. Related factors of hospital performing different procedures included years of performing breast reconstruction, breast surgical volume, and establishment of an independent plastic surgery department. Compared with LDF, abdominal breast reconstruction was associated with a higher flap necrosis rate. CONCLUSIONS This cross-sectional survey offers real-life autologous reconstruction information on a large population and covers the national surgical landscape in China. Autologous reconstruction is still an important part of breast reconstruction. Nevertheless, its low proportion and lower proportion of abdominal flap reconstruction in each institution, demonstrates that special training should be developed for breast surgeons and multidisciplinary cooperation would be promoted in the future.

The Value of Morphometric Measurements in Risk Assessment for Donor-Site Complications after Microsurgical Breast Reconstruction. J Clin Med 2020; 9:jcm9082645. [PMID: 32823954 PMCID: PMC7465816 DOI: 10.3390/jcm9082645] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2020] [Revised: 07/24/2020] [Accepted: 08/11/2020] [Indexed: 12/24/2022] Open
Abstract
Microsurgical abdominally-based reconstruction is considered the gold standard in autologous breast reconstruction. Despite refined surgical procedures, donor-site complications still occur, reducing patient satisfaction and quality of life. Recent work has outlined the potential of morphometric measurements in risk assessment for postoperative hernia development. With rising demand for personalised treatment, the goal of this study was to investigate their potential in risk assessment for any donor site complication. In this retrospective cohort study, 90 patients were included who each received microsurgical breast reconstruction at the hands of one surgeon between January 2015 and May 2017. Donor-site complications formed the primary outcome and were classified according to Clavien-Dindo. Morphometric measurements were taken on a routinely performed computed tomographic angiogram. Complications occurred in 13 of the 90 (14.4%) cases studied. All patients who developed any type of postoperative donor site complication had a history of abdominal surgery. The risk of postoperative complications increased by 3% with every square centimetre of omental fat tissue (OR 1.03, 95% CI 1.00-1.06, and p-value = 0.022). Morphometric measurements provide valuable information in risk assessment for donor-site complications in abdominally-based breast reconstruction. They may help identify personalised reconstructive options for maximal postoperative patient satisfaction and quality of life.

Abstract
BACKGROUND Many factors affect access to immediate breast reconstruction (IR) after mastectomy. The present study was performed to assess trends, outcomes, and predictors of IR techniques using a nationally representative cohort. METHODS The 2009-2014 National Inpatient Sample (NIS) was used to identify adult women who underwent inpatient mastectomy with IR. Patients were compared by type of reconstruction: implant-based IR versus autologous reconstruction (AR). AR was classified as a microsurgical or pedicled flap procedure. Incidence, outcomes, and predictors were assessed using Chi squared univariate tests and multivariable logistic regression analyses. RESULTS Of 194,073 women who underwent IR, 136,668 (70.4%) received implant-based IR and 57,405 (29.6%) received AR. Of those who underwent AR procedures, 31,336 (54.6%) received microsurgical flaps and 26,680 (46.5%) received pedicled flaps. Utilization of deep inferior epigastric perforator (DIEP) flaps increased significantly (28.6-42.5% of AR, P < 0.001). Predictors of AR were Black race [adjusted odds ratio (AOR) = 1.46, P < 0.001], lower Elixhauser Comorbidity Index (AOR = 1.25, P < 0.001), private insurance (AOR = 1.07, P = 0.030), body mass index (BMI) ≥ 30 kg/m2 (AOR = 1.38, P < 0.001), urban teaching hospital designation (AOR = 1.77, P < 0.001), and high hospital volume (AOR = 3.11, P < 0.001). Similar factors were associated with the use of microsurgical flaps. AR and microsurgical flaps were associated with higher rates of acute inpatient complications, resource utilization and length of stay (LOS) compared with implant-based IR and pedicled flaps, respectively. CONCLUSION Implant-based IR remains the most common type of IR, although rates of microsurgical AR are on the rise. Follow-up of complications, costs, and quality-of-life measures may show that AR provides long-term high-value care despite upfront morbidity, cost, and use of hospital resources.

Abstract
Introduction Abdominal wall morbidity after microsurgical breast reconstruction is an important consideration for patients and surgeons. Previous studies are limited by multiple mesh locations or types. In this study, we evaluate specifically subfascial polypropylene mesh placement to determine a more definitive complication rate and basis for objective comparison. Methods A retrospective review was performed for patients undergoing microsurgical breast reconstruction at our institution by 3 surgeons from 2015 to 2018. All patients with sublay placement of polypropylene mesh were included. Patient demographics, medical comorbidities, type of reconstruction, and postoperative abdominal wall complications were recorded. Results A total of 114 flaps were performed on 81 patients who met the inclusion criteria. Of these, 48 were deep inferior epigastric artery (DIEP) flaps (42%), 43 were MS-2 TRAM flaps (37.8%), 20 were muscle sparing (MS-1) transverse rectus abdominus muscle (TRAM) flaps (17.5%), and 3 were free TRAM flaps (2.6%). Average follow-up was 392 days (range: 29-1191). Average body mass index was 30.7. No patients developed hernias. Two patients (2.5%) complained of post-operative bulges, neither of which required operative treatment. Two patients experienced superficial abdominal wall infection, one of which required admission and intravenous antibiotics. Ten patients (12.3%) had abdominal incision dehiscence, 3 of which required operative intervention. There were no cases of mesh exposure, contamination, or removal. Conclusion Polypropylene mesh is safe and effective, with subfascial placement resulting in low morbidity and low rates of bulge/hernia formation after microsurgical breast reconstruction. Consideration should be given to using polypropylene mesh for fascial repairs after microsurgical breast reconstruction, particularly in high-risk populations.

Abstract
PURPOSE Breast cancer survivorship is common (90% of women survive 5 or more years), but many women are not able to return to full function and well-being after treatment due to functional limitations, persistent pain, and inability to perform daily activities. Since each surgical reconstructive option (e.g., autologous tissue flaps versus implants) can impact shoulder and arm function differently, it is important to understand how shoulder and upper limb strength, mobility, and function are influenced by the type of surgical intervention. Efforts can then focus on prehabiliation strategies to prevent the onset of limitations and on developing rehabilitation protocols that directly target shortcomings. METHODS The current paper presents a review summarizing how shoulder and upper limb function may be affected by surgical mastectomy and breast reconstruction. RESULTS Mastectomy and breast reconstruction with implants or autologous tissues present different functional outcomes for patients. Each surgical procedure is associated with unique sequelae derived from the tissues and procedures associated with each surgery. Characterizing the specific functional outcomes associated with each surgical approach will promote the development of targeted rehabilitation strategies that can be implemented into a multidisciplinary treatment planning pathway for breast cancer patients. CONCLUSIONS Surgical treatments for breast cancer, including mastectomy and breast reconstruction, can have negative effects. Focused efforts are needed to better understand treatment-specific effects so that targeted rehabilitation can be developed to improve patient function, QoL, and ability to return to work and life activities post-breast cancer.

Abstract
BACKGROUND Seroma is a common complication after breast surgery such as mastectomy and immediate reconstruction. However, there is a lack of evidence for the utility of drains in the recipient site in delayed autologous breast reconstruction. We reviewed our experience with delayed abdominal-based flap breast reconstruction with a drainless recipient site. METHODS A single-surgeon retrospective case review was performed for delayed abdominal-based flap breast reconstruction using drainless recipient sites from May 2018 to June 2019. Primary outcomes were recipient-site complications. RESULTS Thirty-one delayed abdominal-based flap breast reconstructions that did not use drains in the recipient site were identified in 22 patients. Mean age was 52.8 years (SD, 9.7 years). Mean body mass index was 30.1 kg/m (interquartile range [IQR], 28.2-35.0 kg/m). Common comorbidities were obesity (45.4%), prior tobacco use (31.8%), and diabetes (10.0%). Median time to abdominal-based flap reconstruction was 27.5 months (IQR, 9.9-105.2 months). There were 22 muscle-sparing transverse rectus abdominis musculocutaneous flaps and 9 deep inferior epigastric artery perforator flaps performed. Ten patients (45.4%) underwent bilateral reconstruction. Mean operative time was 302 minutes (SD, 85 minutes). Flap take back occurred in 1 case (3.2%). Mean length of stay was 4 days (SD, 0.8 days). Recipient-site complications were healing complications (32.3%), seroma (3.2%), hematoma (3.2%), and fat necrosis (19.4%). Median follow-up was 4.2 months (IQR, 2.5-11.5). CONCLUSIONS In this case series, our data indicate that delayed autologous reconstruction without drain placement at the recipient site has been proven to be safe and successful and did not increase the rate of seroma or other complications. Adopting a drainless approach may also improve patient comfort and satisfaction.

Abstract
The deep inferior epigastric artery perforator (DIEP) flap is the gold standard for autologous breast reconstruction. When the DIEP pedicle is damaged, alternative perforator flaps are harvested from sites with less donor tissue, such as the thigh. Pedicled superior epigastric artery perforator (SEAP) flaps have been recently described for reconstruction of inferior partial breast defects. The purpose of this report is to show the surgical technique of the free SEAP flap for reconstruction of the entire breast in two patients. The authors describe two patients where the DIEP pedicle was unavailable. The first patient was 53 years old, with body mass index (BMI) 22.7, while the second patient was 60 with BMI 32.4. The donor site was marked as for a DIEP, and two lateral row perforators were selected in each case. Flaps were designed to cross the midline, with adequate perfusion confirmed via indocyanine green angiography. Both flaps were rotated 90° counterclockwise for inset into the chest. Flap size and weight for the two patients were: 24 × 15 cm and 350 g; and 25 × 15 cm and 400 g. Both patients had a routine postoperative course without complications. Length of follow-up was 155 and 158 days, respectively. We believe that the free SEAP flap is a promising technique in select patients who require an alternative to the DIEP for autologous breast reconstruction.

Abstract
BACKGROUND Donor site complications are a significant source of morbidity for patients undergoing abdominal-based free flap breast reconstruction, but there is a paucity of data regarding minimizing these postoperative complications. We hypothesize that selective ablation of the umbilicus at the time of deep inferior epigastric perforator (DIEP) harvest decreases the incidence of umbilical and abdominal wall complications in high-risk patients. METHODS A retrospective review was performed of all patients (n = 117) who underwent DIEP harvest with concomitant umbilical ablation from 2010 to 2015. This cohort was paired with 117 patients who underwent DIEP harvest without umbilical ablation. Preoperative risk factors, intraoperative factors, and postoperative complications were compared. RESULTS The umbilical ablation group had significantly higher body mass index (30.9 vs 27.4 kg/m, P < 0.001), presence of umbilical scar (20.9% vs 5.3%, P < 0.001), umbilical hernia (82.9% vs 8.5% P < 0.001), ventral hernia (23.9% vs 1.7%, P < 0.001), and rectus diastasis (10.3% vs 2.6%, P = 0.016). There were no significant differences of smoking, diabetes mellitus, hypertension, prior abdominal surgery, or midline abdominal scar. The umbilical ablation group had a significantly lower rate of postoperative abdominal wound dehiscence and skin loss (11.1% vs 22.2%, P = 0.023) and overall donor site complications (24.8% vs 39.3%, P = 0.017). There was no significant difference in incidence of cellulitis, seroma, or abscess. Mean follow-up time was 1.8 years. CONCLUSIONS Selective umbilical ablation in high-risk patients at the time of abdominal flap harvest can result in significantly fewer donor site wound complications, even in the setting of increased risk factors for poor wound healing. This is likely due to avoidance of umbilical incisions and decreased upper abdominal skin undermining. We conclude that umbilical ablation is a viable option to minimize donor site complications, especially in high-risk patients.

Abstract
BACKGROUND The pedicled transverse rectus abdominis myocutaneous flap (TRAM) remains an effective and widely-used method for breast reconstruction despite well-documented donor-site morbidity. We present the island-type pedicled TRAM flap as a way to obtain better and more reliable outcomes in breast reconstruction. METHODS A retrospective chart review of patients who underwent breast reconstruction with an island-type pedicled TRAM flap was performed. Patient demographics and complications were reviewed. In the island-type pedicled TRAM flap, we transversely resected the upper ipsilateral rectus muscle surrounding the origin of the superior epigastric vessels, preserving only a 1-cm muscle strip including the vascular pedicle to prevent epigastric bulging and inframammary fold (IMF) disruption. The flap was turned over into the ipsilateral breast pocket. The IMF was repaired except for the portion where the pedicle was placed. RESULTS From January 2013 to November 2017, 88 patients underwent surgery using the island-type pedicled TRAM flap. The etiology of the defect was breast cancer with mastectomy in 86 cases, and paraffinoma in two cases. Seventy-seven patients underwent unilateral reconstruction, and 11 patients underwent bilateral reconstruction. Minor fat necrosis occurred in eight cases. Mild inframammary or epigastric bulging was observed in five cases, and neither partial nor total flap necrosis was observed. The aesthetic outcome of the IMF was evaluated in 55 cases, and 53 cases received good overall scores. CONCLUSION Although the island-type pedicled TRAM flap is technically challenging because careful dissection and pedicle identification is required, it can provide more reliable and better aesthetic results without an increased risk of vascular compromise.

Abstract
BACKGROUND In choosing between implant-based and autologous breast reconstruction, surgeons and patients must weigh relative risks and benefits. However, differences in outcomes across procedure types may vary between unilateral versus bilateral reconstructions. Procedure-related differences in complications and patient-reported outcomes were evaluated for unilateral and bilateral reconstruction. METHODS Complications and patient-reported outcomes (BREAST-Q and Patient-Reported Outcomes measurement Information System surveys) were assessed at 2 years for patients undergoing autologous or implant-based reconstructions. Stratified regression models compared outcomes between autologous and implant-based reconstructions, separately for unilateral and bilateral cohorts. RESULTS Among 2125 patients, 917 underwent unilateral (600 implant and 317 autologous) and 1208 underwent bilateral (994 implant and 214 autologous) reconstructions. Complication rates were significantly higher in the autologous versus implant-based group for both unilateral (overall: OR, 2.50, p < 0.001; major: OR, 2.19, p = 0.001) and bilateral (overall: OR, 2.13, p < 0.001; major: OR, 1.69, p = 0.014) cohorts. In unilateral reconstruction, the autologous group demonstrated significantly better patient-reported outcomes versus implant-based group in satisfaction with breast (mean difference, 9.85; p < 0.001), psychosocial well-being (mean difference, 4.84; p = 0.006), and sexual well-being (mean difference, 11.42; p < 0.001). In bilateral reconstruction, the autologous group demonstrated significantly higher patient-reported outcomes only for satisfaction with breast (mean difference, 5.13; p = 0.001). CONCLUSIONS Although autologous reconstruction is associated with significantly better patient-reported outcomes compared to implant-based techniques in unilateral reconstruction, procedure choice has far less impact in bilateral reconstruction. Autologous procedures have higher complications rates in both unilateral and bilateral settings. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

Abstract
Over the past several decades, technical advances in breast reconstruction have resulted in the development of flaps that are aimed at progressively decreasing abdominal wall morbidity. There is, however, ongoing controversy related to the superiority of deep inferior epigastric perforator (DIEP) flaps over muscle-sparing TRAM (MS-TRAM) flaps. Hence, the question remains unanswered as to which approach should be considered the standard of care, and more importantly, whether the rate of DIEP flap utilization should be considered a quality metric in breast reconstruction. In this review article, we examine the literature pertaining to abdominal free tissue transfer in breast reconstruction from both donor site and flap characteristics as well as the resultant complications and morbidity. The impact on the donor site remains a prevailing principle for autologous breast reconstruction; thus, must be adequately respected when classifying what is left behind following flap harvest. The most commonly used nomenclature is too simplistic. This, in turn, leads to inadequate incorporation of critical variables, such as degree of muscular preservation, fascial involvement, mesh implantation, and segmental nerve anatomy. Currently, there is insufficient evidence to support DIEP flap harvest as a quality indicator in breast reconstruction, as DIEP flap outcomes are not clearly superior when compared with MS-TRAM flaps.

Abstract
Aesthetic and reconstructive breast surgery is among the most common operations performed by plastic surgeons. The prevalence of persistent pain after breast surgery remains underappreciated by plastic surgeons. Post breast surgery pain syndrome (PBSPS) is reported to range between 20-60%. It is the purpose of this paper to revisit chronic pain as a combination of the breast intervention and relate this to the peripheral nerve(s) transmitting the pain message, in order to understand the underlying etiology and to improve breast pain treatment outcomes.

Abstract
BACKGROUND The Breast Reconstruction Assessment (BRA)-score is a disease-specific risk calculator that estimates the likelihood of postoperative complications in an individual patient. The tool has not been previously externally validated in microvascular breast reconstruction. The purpose of this study was to evaluate the efficacy of the calculator in patients who underwent microvascular reconstruction at a single specialist institution. METHODS Data from 415 patients who had immediate microvascular breast reconstruction were entered into the calculator. The predicted and observed rates of surgical complications, medical complications, reoperation, and total or partial flap failure were compared. The accuracy of the calculator was assessed using statistical measures of calibration and discrimination. RESULTS The calculator accurately predicted the proportion of patients who would experience surgical complications and reoperations but overestimated the rates of medical complications and flap failures. The C-statistics were low for all four prediction models (0.49-0.59), suggesting weak discriminatory power, and the Brier scores were relatively high (0.09-0.44), indicating poor correlation between predicted and actual probability of complications. CONCLUSION These results suggest that the BRA score cannot accurately identify patients at risk for complications following immediate microvascular breast reconstruction at our institution.

Abstract
Purpose The incidence of contralateral prophylactic mastectomy (CPM) has continued to increase. We prospectively examined psychosocial outcomes before and up to 18 months after surgery in women who did or did not have CPM. Methods Women with unilateral, nonhereditary breast cancer completed questionnaires before and 1, 6, 12, and 18 months after surgery. Primary psychosocial measures were cancer worry and cancer-specific distress. Secondary measures were body image, quality of life (QOL), decisional satisfaction, and decisional regret. Results A total of 288 women (mean age, 56 years; 58% non-Hispanic white) provided questionnaire data, of whom 50 underwent CPM. Before surgery, women who subsequently received CPM had higher cancer distress ( P = .04), cancer worry ( P < .001), and body image concerns ( P < .001) than women who did not have CPM. In a multivariable repeated measures model adjusted for time, age, race/ethnicity, and stage, CPM was associated with more body image distress ( P < .001) and poorer QOL ( P = .02). There was a significant interaction between time point and CPM group for cancer worry ( Pinteraction < .001), suggesting that CPM patients had higher presurgery cancer worry, but their postsurgery worry decreased over time and was similar to the worry of patients who did not have CPM. QOL was similar between CPM groups before surgery but declined 1 month after surgery and remained lower than patients who did not have CPM after surgery ( Pinteraction = .05). Conclusion These results may facilitate informed discussions between women and their physicians regarding CPM. Fear and worry may be foremost concerns at the time surgical decisions are made, when women may not anticipate the adverse future effect of CPM on body image and QOL.
