Breast reconstruction is associated with improved patient well-being after mastectomy; however, factors that contribute to post-surgical dissatisfaction remain poorly characterized. Adult women who underwent post-mastectomy implant-based or autologous breast reconstruction between 2015 and 2019 were recruited to participate in semi-structured interviews regarding their lived experiences with reconstructive care. Participants completed the BREAST-Q, and tabulated scores were used to dichotomize patient-reported outcomes as satisfied or dissatisfied (high or low) for each BREAST-Q domain. A convergent mixed-methods analysis was used to evaluate interviews for content related to satisfaction or dissatisfaction with breast reconstruction. Overall, we interviewed 21 women and identified 17 subcodes that corresponded with the five BREAST-Q domains. Sources of dissatisfaction were found to be related to the following domains: (a) low breast satisfaction due to asymmetry, cup size, and lack of sensation and physical feeling (n = 8, 38%); (b) poor sexual well-being due to shape, look and feel (n = 7, 78% [of 9 who discussed sexual well-being]); (c) reduced physical well-being of the chest due to persistent pain and weakness (n = 11, 52%); (d) reduced abdominal well-being due to changes in abdominal strength, numbness, and posture (n = 6, 38% [of 16 who underwent abdominally based reconstruction]); and (e) low psychosocial well-being impacted by an unexpected appearance that negatively influenced self-confidence and self-identity (n = 13, 62%). Patients may be unprepared for the physical, sexual, and psychosocial outcomes of breast reconstruction. Targeted strategies to improve preoperative education and shared decision making are needed to mitigate unexpectedness associated with breast reconstruction and related outcomes.

Background Scar revisions have been increasing in number. Patient-reported outcome measures are one tool to aid scar modulation decision-making. The aims of this study were to determine patient, scar, and clinical risk factors for (1) low SCAR-Q Appearance, Symptom, and Psychosocial Impact scores and how this differs for children; and (2) the potential need for future scar revision surgery to better identify such patients in a clinical setting. Methods A multicenter international cross-sectional cohort study based on survey data of participants with traumatic, surgical, and burn scars attending plastic, hand, and burn clinics in four countries was conducted following the Strengthening the Reporting of Observational Studies in Epidemiology checklist. Univariate analysis to identify risk factors and multivariable logistic analysis to select risk factors were completed. Collinearity for nonindependent factors and C statistic for model discrimination were also calculated. Results Seven hundred thirty-one participants completed the study booklet, and 546 participants (74.7 percent) had full data. Independent risk factors were determined to be a bothersome scar and perception of scarring badly for all three scales. Risk factors for self-reporting the need for future surgery included a health condition, scarring badly, scar diagnosis, prior scar revision, and low Psychosocial Impact scores. We did not identify evidence of multicollinearity. C statistics were high (0.81 to 0.84). Conclusions This study is the first multicenter international study to examine independent risk factors for low patient-reported outcome measure scores and the potential need for future scar revision surgery. Patients that perceive themselves as scarring badly and having a bothersome scar were at a higher risk of scar appearance concern, an increased symptom burden, and poorer psychosocial impact scores.

BACKGROUND Given the competition in the integrated plastic surgery Match, away rotations are ubiquitous among plastic surgery applicants to differentiate their applications. This study aimed to characterize how performing an away rotation affects rank order and Match outcomes for integrated plastic surgery programs. METHODS An online survey was designed and distributed to the top 25 integrated plastic surgery programs in the United States as determined by Doximity. Programs were polled about away rotation structure, position of rotators on their 2018 to 2019 rank list, and composition of current resident classes. RESULTS Twenty-five programs completed the survey (response rate, 100 percent). On average, programs interviewed 34.9 applicants (range, 22 to 50 applicants) and ranked 32.8 applicants (range, 10 to 50 applicants). Most "ranked-to-match" positions were occupied by home students or away rotators (60.9 percent). Rank order of home students, away rotators, and nonrotators varied significantly (p < 0.001), with median rank order of home students [5 (interquartile range, 1 to 9)] and rotators [14 (interquartile range, 6 to 27)] higher than nonrotators [17 (interquartile range, 10 to 29)]. Rank orders of away rotators tended to follow a bimodal distribution. Furthermore, 64.4 percent of integrated residents were either a home student or away rotator at their matched integrated program, with 20 percent of residency programs composed of greater than 70 percent of away rotators/home students across postgraduate years 1 through 6 classes. CONCLUSIONS For integrated plastic surgery programs, the majority of ranked-to-match students on rank lists and current residents were either home students or away rotators at their respective program. Performing well on an away rotation appears to confer significant benefit to the applicant applying in the integrated plastic surgery Match.

Background While bipedicled free flaps enable increased soft tissue volume and potential for contralateral symmetry in unilateral breast reconstruction, the influence of bipedicled flap reconstruction on patient-reported outcomes remains unclear. Methods Patients undergoing unilateral free flap breast reconstruction at a single institution from 2014 to 2019 were retrospectively reviewed and sent the BREAST-Q and Decision Regret Scale. Complication rates and the BREAST-Q and Decisional Regret Scale scores (0–100) were compared between patients receiving bipedicled total abdominal and unipedicled hemiabdominal free flaps. Results Sixty-five patients undergoing unilateral breast reconstruction completed the BREAST-Q and Decision Regret Scale with median (interquartile range [IQR]) follow-up time of 32 [22–55] months. Compared with bipedicled flaps, patients receiving unipedicled hemiabdominal flaps had higher mean body mass index (BMI; p = 0.009) and higher incidence of fat grafting (p = 0.03) and contralateral reduction mammaplasties (p = 0.03). There was no difference in incidence of major or minor complications, abdominal hernias or bulges, or total operative time between bipedicled and unipedicled flaps (p > 0.05). Overall, BREAST-Q scores for satisfaction with breast, sexual wellbeing, psychosocial wellbeing, physical wellbeing (chest), and physical wellbeing (abdomen) and the Decision Regret Scale scores did not significantly vary between bipedicled and unipedicled reconstructions (all p > 0.05). However, among large-breasted patients (≥C cup), mean (standard deviation [SD]) sexual wellbeing was significantly higher after bipedicled total abdominal free flap reconstruction ([60.2 (23.3) vs. 46.2 (22.0)]; p = 0.04), though this difference did not reach significance after multivariate adjustment. Conclusion Unilateral breast reconstruction with bipedicled total abdominal free flaps results in similar complication risk, patient satisfaction, and decisional regret without the need for as many contralateral reduction procedures.

Background Psychosocial distress, depression, or anxiety can occur in up to 50% of women after a breast cancer diagnosis and mastectomy. The purpose of this study was to assess the potential benefit of lavender oil as a perioperative adjunct to improve anxiety, depression, pain, and sleep in women undergoing microvascular breast reconstruction. Methods This was a prospective, single-blinded, randomized, controlled trial of 49 patients undergoing microvascular breast reconstruction. Patients were randomized to receive lavender oil or placebo (coconut oil) throughout their hospitalization. The effect of lavender oil on perioperative stress, anxiety, depression, sleep, and pain was measured using the hospital anxiety and depression scale, Richards–Campbell Sleep Questionnaire, and the visual analogue scale. Results Twenty-seven patients were assigned to the lavender group and 22 patients were assigned to the control group. No significant differences were seen in the perioperative setting between the groups with regard to anxiety (p = 0.82), depression (p = 0.21), sleep (p = 0.86), or pain (p = 0.30) scores. No adverse events (i.e., allergic reaction) were captured, and no significant differences in surgery-related complications were observed. When evaluating the entire cohort, postoperative anxiety scores were significantly lower than preoperative scores (p Conclusion In the setting of microvascular breast reconstruction, lavender oil and aromatherapy had no significant adverse events or complications; however, there were no measurable advantages pertaining to metrics of depression, anxiety, sleep, or pain as compared with the control group.

BACKGROUND: Women of color with breast cancer are less likely to undergo post-mastectomy reconstruction compared with White women, but it is unclear whether their perioperative outcomes are worse. The goal of this study was to investigate differences in preoperative comorbidities and postoperative complications by race/ethnicity among women with breast cancer undergoing postmastectomy reconstruction. STUDY DESIGN: Data were collected from the National Inpatient Sample database of the Healthcare Cost and Utilization Project from 2012 to 2016. Patient demographics, types of reconstruction, comorbid conditions, Charlson-Deyo Combined Comorbidity (CDCC) scores, length of stay (LOS), and perioperative complications were abstracted. Multivariate linear and logistic regression were performed to model LOS and likelihood of postoperative complications, respectively. RESULTS: Compared with White women (n = 19,730), Black women (n = 3,201) underwent autologous reconstruction more frequently (40.7% vs 28.3%), had more perioperative comorbidities (eg diabetes: 12.9% vs 5.8%), higher CDCC scores (% CDCC ≥ 4: 5.5% vs 2.7%), and longer LOS (median 3 vs 2 days, all p < 0.001). Being Black (vs white: +0.13 adjusted days, 95% CI 0.06 to 0.19) was also associated with longer LOS and an increased likelihood of surgical complications (vs White: odds ratio 1.24, 95% CI 1.09 to 1.42, both p < 0.01), but this association did not persist when outcomes were limited to microsurgical complications. CONCLUSION: Disparities in postmastectomy breast reconstruction between Black and White women extend beyond access to care and include perioperative factors and outcomes. These findings suggest an important opportunity to mitigate inequities in reconstruction through perioperative health optimization and improved access to and co-management with primary care.

Limited visibility characteristic of cleft palate repair presents both ergonomic and educational challenges to cleft surgeons. Despite widespread recognition and reporting, posture-related spine disorders continue to represent a significant and potentially career-limiting problem for cleft/craniofacial surgeons. In addition, education and participation during palate repairs is difficult because of visual field constraints. At the authors' institution, a novel videoscope system was designed and implemented to (1) provide visualization for all surgical team members during palate operations, (2) facilitate active resident education, and (3) improve surgeon ergonomics. The authors' prior report demonstrated proof of concept for this method, which is now used in all cleft palate operations at their center. The purpose of this report is to share the detailed methodology to facilitate implementation by others and a retrospective review of the authors' experience before and after implementation. Video demonstration of the videoscope setup and a representative, recorded case are provided. The use of the videoscope was feasible in palatoplasties regardless of palatal phenotype and repair technique and did not have an effect on operative time. Subjectively, the authors report reduced procedure time in cervical flexion and subjectively improved musculoskeletal strain associated with videoscope use. Importantly, use of this system also provided complete visualization for all operating room team members and enabled enhanced resident autonomy during palate operations. Finally, it has facilitated the creation and archive of high-definition educational videos with unparalleled perspective. The equipment required to implement the system is likely already available in many medical centers. Adoption of this system may provide an opportunity to improve posture and teaching capabilities for cleft surgeons. CLINICAL QUESTION/LEVEL OF EVIDENCE:: Therapeutic, III.

INTRODUCTION As a profession, plastic surgeons must meet the public demand for aesthetic and reconstructive procedures. Patients search for physicians using Google, which offers insights into patient needs through their search history. METHODS The Google Trends Relative Search Volumes (RSV) were pulled for all searches for “plastic surgery” over 12 months. The number of active plastic surgeons per state was divided by Census Bureau population estimates to calculate the surgeons-per-capita value, or “surgical concentration.” The Google score divided by this concentration yields a “surgical demand index” for each state. RESULTS Florida, New York, and Connecticut had the greatest concentration of surgeons per ten-thousand people (0.220, 0.217, and 0.209, respectively), while Wyoming, Arkansas, and Vermont had the smallest (0.051, 0.071, 0.080). California exhibited the greatest number of Google searches (RSV=100), followed by Florida and Hawaii (RSV=95). Oregon (RSV=38), Virginia (RSV=52), and Alaska (RSV=58) had the fewest searches. The “surgical demand index” was greatest in Wyoming (1187.778), Oklahoma (993.751), and Arkansas (974.664) and smallest in Oregon (264.682), Virginia (320.716), and Connecticut (354.872). CONCLUSION The distribution of US plastic surgeons is not homogeneous. The Google data suggest that some markets (e.g. Oregon) are saturated while others (e.g. Wyoming) have significant demand that is not met by the number of plastic surgeons in those states.

BACKGROUND Musculoskeletal symptoms and injuries among surgeons are underestimated but are increasingly recognized to constitute a major problem. However, it has not been established when symptoms start and what factors contribute to the development of symptoms. METHODS A 19-question survey approved by our institution's review board, and American Council of Academic Plastic Surgery was sent to all plastic surgery residents enrolled in Accreditation Council for Graduate Medical Education-accredited plastic surgery training programs in the United States. The presence of various musculoskeletal symptoms was calculated, and predictors of these symptoms were evaluated. RESULTS We received 104 total responses. Ninety-four percent of residents had experienced musculoskeletal pain in the operating room. The neck was the most commonly affected area (54%) followed by the back (32%) and extremities (12%). Interestingly, 52% of responders developed these symptoms during the first 2 years of their residency. Furthermore, increasing postgraduate year level (P = 0.3) and independent versus integrated status (P = 0.6) had no correlation with pain, suggesting that symptoms began early in training.Pain symptoms were frequent for 47%, whereas 5% reported experiencing symptoms during every case. The use of a headlight correlated with frequent pain (odds ratio, 2.5; P = 0.027). The use of microscope and loupes did not correlate with frequent pain. Eighty-nine percent of responders were aware of having bad surgical posture, but only 22% had received some form of ergonomics training at their institution. Sixty-four percent of responders believe that the operating room culture does not allow them to report the onset of symptoms and ask for adjustments. This was more common among residents reporting frequent pain (odds ratio, 3.12; P = 0.009). CONCLUSIONS Plastic surgeons are at high risk for occupational symptoms and injuries. Surprisingly, symptoms start early during residency. Because residents are aware of the problem and looking for solutions, this suggests an opportunity for educational intervention to improve the health and career longevity of the next generation of surgeons.

Background Limb-threatening lower extremity traumatic injuries can be devastating events with a multifaceted impact on patients. Therefore, evaluating patient-reported outcomes (PROs) in addition to traditional surgical outcomes is important. However, currently available instruments are limited as they were not developed specific to lower extremity trauma patients and lack content validity. The LIMB-Q is being developed as a novel PRO instrument to meet this need, with the goal to measure all relevant concepts and issues impacting amputation and limb-salvage patients after limb-threatening lower extremity trauma. Methods This is a qualitative interview-based study evaluating content validity for the LIMB-Q. Patients aged 18 years and older who underwent amputation, reconstruction, or amputation after failed reconstruction were recruited using purposeful sampling to maximize variability of participant experiences. Expert opinion was solicited from a variety of clinical providers and qualitative researchers internationally. Preliminary items and scales were modified, added, or removed based on participant and expert feedback after each round of participant interviews and expert opinion. Results Twelve patients and 43 experts provided feedback in a total of three rounds, with changes to the preliminary instrument made between each round. One scale was dropped after round one, one scale was added after round two, and only minor changes were needed after round three. Modifications, additions and removal of items, instructions, and response options were made after each round using feedback gathered. Conclusion The LIMB-Q was refined and modified to reflect feedback from patients and experts in the field. Content validity for the LIMB-Q was established. Following a large-scale field test, the LIMB-Q will be ready for use in research and clinical care.

Background Severe lower extremity injuries are challenging to treat. The aspects of limb salvage and amputation most important to patients are not well-defined. This study's aim is to develop a conceptual framework for a patient-reported outcome instrument for lower extremity trauma patients, by defining issues and concepts most important to this patient population. Methods This is an interpretative description of transcripts collected from semistructured qualitative interviews at a single institution. High-energy lower extremity trauma patients were recruited by means of purposeful sampling to maximize variability. Thirty-three participant interviews were needed to reach content saturation. These participants were aged 19 to 79 years; 21 were men (63.6 percent); participation was after reconstruction [n= 15 (45.5 percent)], after amputation [n = 11 (33.3 percent)], or after amputation after failed reconstruction [n = 7 (21.2 percent)]. Interviews were recorded, transcribed, and coded line-by-line. Concepts were labeled with major and minor themes and refined through a process of constant comparison. Analysis led to the development of a conceptual framework and item pool to inform the development of a patient-reported outcome measure. Results In total, 2430 unique codes were identified and used to generate the conceptual framework covering 10 major themes: appearance, environment, finances, physical, process of care, prosthesis, psychological, sexual, social, and treatment. Conclusions This study establishes a comprehensive set of concepts, identifying what is most important to severe lower extremity trauma patients. These findings can be used to inform and focus research and clinical care, and provides the framework to develop a lower extremity trauma-specific patient-reported outcome instrument: the LIMB-Q.

Background Lower extremity reconstruction is often a challenging prospect with major implications on a patient’s quality of life. For complex defects of the lower extremity, special consideration must be given to ensure suitable and durable coverage. In the following article, we present the essential local muscle flaps for lower extremity reconstruction and discuss guiding principles for the reconstructive surgeon to consider. Methods A thorough literature review was performed using PubMed to identify commonly used local muscle flaps for lower extremity reconstruction. Common considerations for each identified flap were noted. Results The essential local muscle flaps for lower extremity reconstruction were identified and classified based on anatomical region of the defect to be reconstructed. General considerations and postoperative management were discussed to aid in operative decision making. Conclusion While many factors must be taken into account when performing lower extremity reconstruction, there are numerous reliable local muscle flaps which can be used to successfully provide durable coverage for a variety of soft tissue defects of the lower extremity.

BACKGROUND Enhanced recovery after surgery (ERAS) initiatives improve postoperative function and expedite recovery, leading to a decrease in length of stay. The authors noted a high rate of postoperative symptomatic hypotension in patients undergoing abdominal free flap breast reconstruction and wished to explore this observation. METHODS Subjects undergoing abdominal free flap breast reconstruction at the authors' institution from 2013 to 2017 were identified. The ERAS protocol was initiated in 2015 at the authors' hospital; thus, 99 patients underwent traditional management and 138 patients underwent ERAS management. Demographics and perioperative data were collected and analyzed. Postoperative symptomatic hypotension was defined as mean arterial pressure below 80 percent of baseline with symptoms requiring evaluation. RESULTS A significantly higher rate of postoperative symptomatic hypotension was observed in the ERAS cohort compared with the traditional management cohort (4 percent versus 22 percent; p < 0.0001). Patients in the ERAS cohort received significantly less intraoperative intravenous fluid (4467 ml versus 3505 ml; p < 0.0001) and had a significantly increased amount of intraoperative time spent with low blood pressure (22 percent versus 32 percent; p =0.002). Postoperatively, the ERAS cohort had significantly lower heart rate (77 beats per minute versus 88 beats per minute; p < 0.0001) and mean arterial pressure (71 mmHg versus 78 mmHg; p < 0.0001), with no difference in urine output or adverse events. CONCLUSIONS The authors report that ERAS implementation in abdominal free flap breast reconstruction may result in a unique physiologic state with low mean arterial pressure, low heart rate, and normal urine output, resulting in postoperative symptomatic hypotension. Awareness of this early postoperative finding can help better direct fluid resuscitation and prevent episodes of symptomatic hypotension. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

Background Free-flap breast reconstruction after failed implant reconstruction is associated with improved patient outcomes. How the level of satisfaction achieved compares between patients with and without previously failed implant reconstruction remains unknown. The aim of this study was to assess the influence of prior failed implant-based reconstruction on long-term patient-reported outcomes after free-flap breast reconstruction. Methods All patients undergoing free-flap breast reconstruction between 2015 and 2019 were identified. Patient satisfaction using the BREAST-Q and decisional regret using the Decision Regret Scale were compared between patients with and without a history of implant breast reconstruction. Results Overall, 207 patients were contacted and 131 completed the BREAST-Q and Decision Regret Scale. A total of 23 patients had a history of failed implant-based reconstruction requiring free-flap-flap salvage, most commonly due to infection (39.1%), chronic pain (34.8%), capsular contracture (26%), and implant malposition (26.1%). Following definitive free-flap reconstruction, patients with prior failed implant reconstruction had significantly lower BREAST-Q scores for satisfaction with breast (61.2 ± 16.7 vs. 70.4 ± 18.7; p = 0.04) and sexual well-being (38.5 ± 18.2 vs. 52.8 ± 24.7; p = 0.01) and reported higher decision regret (19.1 ± 18.6 vs. 9.6 ± 15.6, respectively). There were no significant differences for psychosocial well-being (p = 0.67), physical well-being (chest; p = 0.27), and physical well-being (abdomen; p = 0.91). Conclusion A history of failed implant-based reconstruction is associated with reduced satisfaction and increased decision regret with the final reconstructive outcome. This data underscores the importance of appropriate patient selection at the initial consultation, and informed preoperative counseling regarding long-term outcomes in patients presenting for free-flap reconstruction after a failed implant-based reconstruction.

BACKGROUND Plastic surgeons are evaluated not only by the number of patients served but also by relative value, quantified by the Medicare relative value unit system, which can affect advancement and compensation. Procedures that demand a high operative time without an increase in relative value units are, by definition, inefficient. The purpose of this study was to determine whether the number of relative value units actually corresponds to operative time. METHODS The National Surgical Quality Improvement Program data sets over a 9-year period were queried for plastic surgery operations. The primary CPT codes representing the 100 most common operations were compared for operative time and total relative value units. RESULTS A total of 53,701 cases were included. There was a high degree of correlation between operative time and number of relative value units (Pearson correlation coefficient, 0.82). The average efficiency was 10.201 ± 3.386 relative value units per hour. Pressure ulcer excisions and breast reconstruction were among the most efficient (e.g., Excision, sacral pressure ulcer, CPT 19357, generated 20.819 relative value units per hour). Skin excisions, debridements, and flap delays were among the least efficient (e.g., Excision, excessive skin and subcutaneous tissue, CPT 15847, generated 1.752 relative value units per hour). CONCLUSIONS As a general trend, the most common plastic surgical procedures requiring longer operative times are associated with more relative value units. Cases with higher relative value units assigned tended to be more efficient. For the 100 most common procedures, relative value units and operative time are not evenly distributed. These data suggest modifications to the current relative value unit designation system to more equally allocate these units based on effort and time.

BACKGROUND Patients undergoing mastectomy may not be candidates for immediate free-flap breast reconstruction because of medical comorbidities or postmastectomy radiation therapy. In this setting, flap reconstruction may be intentionally delayed or staged with tissue expander placement ("delayed-immediate" reconstruction). The optimal reconstructive choice and incidence of complications for these approaches remain unclear. METHODS The authors retrospectively identified patients who underwent delayed [n = 140 (72 percent)] or staged [n = 54 (28 percent)] abdominal free-flap breast reconstruction between 2010 and 2018 and compared the incidence of postoperative complications. RESULTS Patients undergoing staged reconstruction had a higher overall incidence of perioperative complications, including surgical-site infection (40.7 percent versus 6.5 percent; p < 0.001), wound healing complications (29.6 percent versus 12.3 percent; p = 0.004), hematoma (11.1 percent versus 0.7 percent; p < 0.001), and return to the operating room (27.8 percent versus 4.4 percent; p < 0.0001). These complications occurred predominately during the expansion stage, resulting in an 18.5 percent (n = 10) rate of tissue expander failure. Mean time from mastectomy to flap reconstruction was 476.8 days (delayed, 536.4 days; staged, 322.4 days; p < 0.001). At the time of flap reconstruction, there was no significant difference in the incidence of complications between the staged cohort versus the delayed cohort, including microsurgical complications (1.9 percent versus 4.3 percent; p = 0.415), total flap loss (0 percent versus 2.1 percent; p = 0.278), or fat necrosis (5.6 percent versus 5.0 percent; p = 0.875). CONCLUSIONS The aesthetic and psychosocial benefits of staged free-flap breast reconstruction should be balanced with the increased risk of perioperative complications as compared to a delayed approach. Complications related to definitive flap reconstruction do not appear to be affected by the approach taken at the time of mastectomy. . CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

Background In the setting of radiation therapy or significant medical comorbidities, free-flap breast reconstruction may be intentionally delayed or staged with tissue expander placement ("delayed-immediate" approach). The effect of a staged approach on patient satisfaction and decisional regret remains unclear. Methods All patients undergoing free-flap breast reconstruction (n = 334) between 2014 and 2019 were identified. Complication rates, patient satisfaction using the BREAST-Q, and decisional regret using the Decision Regret Scale were compared between patients undergoing immediate, delayed, and staged approaches. Results Overall, 100 patients completed the BREAST-Q and Decision Regret Scale. BREAST-Q scores for psychosocial well-being (P = 0.19), sexual well-being (P = 0.26), satisfaction with breast (P = 0.28), physical well-being (chest, P = 0.49), and physical well-being (abdomen, P = 0.42) did not significantly vary between patients undergoing delayed, staged, or immediate reconstruction. Overall, patients experienced low regret after reconstruction (mean score, 11.5 ± 17.1), and there was no significant difference in regret scores by reconstruction timing (P = 0.09). Compared with normative BREAST-Q data, unlike immediate and delayed approaches, staged reconstruction was associated with lower sexual well-being (P = 0.006). Furthermore, a significantly higher infection rate was seen among staged patients (immediate 0%, delayed 5%, staged 20%, P = 0.01). Conclusions Staged free-flap breast reconstruction confers similar long-term satisfaction and decisional regret as immediate and delayed reconstruction but may be associated with worsened sexual well-being, when compared with normative data, and an increased risk of surgical site infection. When counseling patients regarding the timing of reconstruction, it is important to weigh these risks in the context of equivalent long-term satisfaction and decisional regret between immediate, delayed, and staged approaches.

Complications from breast reconstruction may delay postmastectomy radiation therapy and impact breast cancer outcomes. The authors hypothesized that immediate breast reconstruction may be associated with delays in the initiation of radiation, but that this delay would not significantly impact overall patient survival.Using the National Cancer Database, the authors identified women with breast cancer who underwent mastectomy and received postmastectomy radiation therapy. Delayed radiation was defined as treatment initiated 6 months or more after surgery in patients who received adjuvant chemotherapy or 12 weeks or more after surgery in patients who received neoadjuvant or no chemotherapy.Women undergoing breast reconstruction had an increased time to postmastectomy radiation therapy, 154 days versus 132 days (p0.001), and were more likely to experience a delay in initiating radiation (OR, 1.25; 95 percent CI, 1.188 to 1.314). Other factors associated with delayed radiation included increased Charlson/Deyo scores, neoadjuvant chemotherapy, nonprivate insurance, and black race. Cox proportional hazards models revealed no evidence of a reduced adjusted overall survival in the immediate breast reconstruction group (hazard ratio, 0.836; 95 percent CI, 0.802 to 0.871; p0.001). Restricted cubic spline analysis identified the threshold number of days at which the start of radiation began to impact survival at 169 days (95 percent CI, 160 to 190 days), 75 days (95 percent CI, 42 to 90 days), and 71 days (95 percent CI, 41 to 90 days) in patients undergoing adjuvant, neoadjuvant, and no chemotherapy, respectively.Immediate breast reconstruction is associated with a modest delay in initiating postmastectomy radiation therapy but does not impact overall survival.Therapeutic, III.

Marital status is known to influence quality of life, survival, and treatment decision-making after breast cancer diagnosis. We aimed to determine whether relationship status impacts contemporary patterns of immediate breast reconstruction.Surveillance, Epidemiology, and End Results (SEER)-18 was used to identify females undergoing mastectomy for stage 0-III breast cancer from 1998 to 2014. Multivariate logistic regression was used to estimate the association of relationship status with the likelihood of postmastectomy reconstruction. Patients were grouped by diagnosis year to assess change in the reconstructed population with time. Among younger patients ≤45 years, a generalized logistic model was used to predict reconstruction subtype.Among 346,418 patients, reconstruction after mastectomy was more likely to occur in women with relationship support in the form of a marriage or partner [odds ratio (OR) 1.31; 95% confidence interval (CI), 1.28-1.34; p0.001]. Women who were separated (OR 0.76), single (OR 0.73), or widowed (OR 0.56) were significantly less likely than married women to undergo reconstruction (all p0.001). During the 17-year study period, change in reconstruction rates with time varied by relationship status (interaction p=0.02), with reconstruction rates among divorced patients increasing more slowly than those among married and partnered women. Among younger women, subtype patterns varied by relationship status (p=0.004), with divorced women less likely to receive autologous over implant reconstruction (OR 0.87; p = 0.03).Relationship status may influence decision-making regarding pursuit and type of postmastectomy reconstruction. Consideration of support networks of patients with breast cancer could facilitate tailored preoperative counseling by reconstructive surgeons.

The hypoxia-inducible factor (HIF) pathway, regulated by prolyl hydroxylase, is central to tissue adaptation to ischemia. The authors tested whether the prolyl hydroxylase inhibitor dimethyloxalylglycine reduces skin flap necrosis.Dorsal skin flaps were raised on hairless rats, with dimethyloxalylglycine delivered intraperitoneally and/or topically for 7 days before and after surgery. After 14 treatment days, percentage of flap necrosis was compared grossly and tissue perfusion compared with an in vivo imaging system. Angiogenesis was compared using immunohistochemical CD31 staining and enzyme-linked immunosorbent assay for tissue vascular endothelial growth factor. Expression levels of HIF-1α and terminal deoxynucleotidyl transferase-mediated dUDP end-labeling were compared using immunohistochemical staining. Complete blood counts and gross necropsy specimens were obtained to assess systemic toxicity.Dimethyloxalylglycine administration significantly improved postoperative flap viability, with combined topical and intraperitoneal dimethyloxalylglycine administration leading to reduced necrosis on postsurgical day 7 at 6 mg/kg/day, 12 mg/kg/day, 24 mg/kg/day, and 48 mg/kg/day versus controls (all p0.05). Compared with controls (unperfused, 39.9 ± 3.8 percent), dimethyloxalylglycine treatment led to a dose-dependent decrease in unperfused tissue at 6 mg/kg/day (11.4 ± 1.7 percent), 12 mg/kg/day (9.4 ± 4.2 percent), 24 mg/kg/day (4.7 ± 2.6 percent), and 48 mg/kg/day (1.4 ± 0.9 percent) (all p0.001). Topical dimethyloxalylglycine application alone administered at 48 mg/kg/day was sufficient to improve flap viability (p = 0.005). Dimethyloxalylglycine-treated flaps exhibited higher CD31 staining (p = 0.004), tissue vascular endothelial growth factor (p = 0.007), HIF-1α staining (p0.001), and reduced terminal deoxynucleotidyl transferase-mediated dUDP end-labeling staining (p = 0.045). There were no differences in hematocrit or macroscopic organ changes on gross necropsy.Topical and systemic targeting of the HIF-1 pathway may be a promising therapeutic approach to improve flap resistance to ischemia.

The tumor microenvironment within the breast is rich in adipose elements. The interaction between adipose cells and breast cancer is poorly understood, particularly as it pertains to patients with genetic susceptibility to breast cancer. This study focuses on the phenotype of human adipose-derived stem cells with the BRCA1 mutation and the effect they may have on breast cancer cell behavior.CRISPR/Cas9 was used to generate de novo BRCA1-knockdown human adipose-derived stem cells. The effect of the BRCA1 knockdown on the adipose-derived stem cell phenotype was compared to wild-type adipose-derived stem cells and patient-derived breast adipose-derived stem cells with known BRCA1 mutations. Interactions between adipose-derived stem cells and the MDA-MB-231 breast cancer cell line were evaluated.BRCA1-knockdown adipose-derived stem cells stimulated MDA-MB-231 proliferation (1.4-fold increase on day 4; p = 0.0074) and invasion (2.3-fold increase on day 2; p = 0.0171) compared to wild-type cells. Immunofluorescence staining revealed higher levels of phosphorylated ataxia telangiectasia-mutated activation in BRCA1-knockdown cells (72.9 ± 5.32 percent versus 42.9 ± 4.97 percent; p = 0.0147), indicating higher levels of DNA damage. Beta-galactosidase staining demonstrated a significantly higher level of senescence in BRCA1-knockdown cells compared with wild-type cells (7.9 ± 0.25 percent versus 0.17 ± 0.17 percent; p0.0001). Using quantitative enzyme-linked immunosorbent assay to evaluate conditioned media, the authors found significantly higher levels of interleukin-8 in BRCA1-knockdown cells (2.57 ± 0.32-fold; p = 0.0049).The authors show for the first time that the BRCA1 mutation affects the adipose-derived stem cell phenotype. Moreover, CRISPR/Cas9-generated BRCA1-knockdown adipose-derived stem cells stimulate a more aggressive behavior in breast cancer cells than wild-type adipose-derived stem cells. This appears to be related to increased inflammatory cytokine production by means of a DNA damage-mediated cell senescence pathway.

Purpose Most triple-negative breast cancer (TNBC) patients exhibit an incomplete response to neoadjuvant chemotherapy, resulting in chemo-residual tumor cells that drive tumor recurrence and patient mortality. Accordingly, strategies for eliminating chemo-residual tumor cells are urgently needed. Although stromal cells contribute to tumor cell invasion, to date, their ability to influence chemo-residual tumor cell behavior has not been examined. Our study is the first to investigate cross-talk between adipose-derived stem cells (ASCs) and chemo-residual TNBC cells. We examine if ASCs promote chemo-residual tumor cell proliferation, having implications for tumor recurrence. Methods ASC migration toward chemo-residual TNBC cells was tested in a transwell migration assay. Importance of the SDF-1α/CXCR4 axis was determined using neutralizing antibodies and a small molecule inhibitor. The ability of ASCs to drive tumor cell proliferation was analyzed by culturing tumor cells ± ASC conditioned media (CM) and determining cell counts. Downstream signaling pathways activated in chemo-residual tumor cells following their exposure to ASC CM were studied by immunoblotting. Importance of FGF2 in promoting proliferation was assessed using an FGF2-neutralizing antibody. Results ASCs migrated toward chemo-residual TNBC cells in a CXCR4/SDF-1α-dependent manner. Moreover, ASC CM increased chemo-residual tumor cell proliferation and activity of extracellular signal-regulated kinase (ERK). An FGF2-neutralizing antibody inhibited ASC-induced chemo-residual tumor cell proliferation. Conclusions ASCs migrate toward chemo-residual TNBC cells via SDF-1α/CXCR4 signaling, and drive chemo-residual tumor cell proliferation in a paracrine manner by secreting FGF2 and activating ERK. This paracrine signaling can potentially be targeted to prevent tumor recurrence.

Purpose: Our laboratory studies contributions of breast adipose stromal cells (bASCs) to breast cancer initiation and progression. To date, most studies of ASC biology have focused on abdominal ASCs. We hypothesize that bASC biology impacts the breast microenvironment in a manner that influences a woman’s risk of developing breast cancer. Methods: In order to better understand how aberrant bASC biology contributes to breast cancer, we built a bASC cell repository from women undergoing mastectomies at Duke University Hospital (Duke IRB Pro00100739). Some of these women are at high risk for developing breast cancer. High risk biology includes women with genetic predispositions to cancer, as well as obese and post-menopausal women. bASCs were isolated from the stromal vascular fraction of breast adipose tissue from patients. Additionally, commercially-available ASCs isolated from the abdomen were obtained from Zenbio. Senescence was measured in bASCs using the SPiDER beta gal senescence detection kit (Dojingo). Senescence-associated cytokines were measured in conditioned media collected from these bASCs by ELISA (R&D Systems). The ability of bASCs to differentiate into adipocytes was measured using the Adipo-Red adipocyte differentiation assay (Lonza). Results: To date, we have isolated bASCs from 16 patients undergoing mastectomies at Duke University Hospital. We have studied differences in the biology of these bASCs that may be associated with increased breast cancer risk. A commonality observed in high risk patients was senescence, demonstrated by bASCs undergoing growth arrest and secretion of beta-galactosidase. Similarly, bASCs from high risk patients demonstrated secretion of inflammatory cytokines such as Interleukin-6 (IL-6), Interleukin-8 (IL-8), and Interleukin-1beta (IL-1 beta) that are associated with the senescence-associated secretory phenotype. We hypothesize that the secretion by these bASCs of such cytokines creates an inflammatory breast microenvironment that increases breast cancer risk. Our data also indicate that bASCs from high risk patients exhibit a defect in their ability to differentiate into adipocytes. Conclusion: Our studies are the first to report on a repository of breast ASCs (bASCs) from patients undergoing mastectomies. Results indicate that bASC biology differs significantly amongst patients, with a subset exhibiting a senescent secretory phenotype associated with a block in their ability to differentiate into adipocytes. We hypothesize bASC senescence, associated with a senescence secretory phenotype, results in: 1) the inability of these bASCs to differentiate into adipocytes, and 2) a senescence-associated secretory phenotype that impacts the breast tumor microenvironment. As we continue to build the repository, studies are in progress to test if inflammatory cytokines secreted by senescent bASCs work in a paracrine fashion on breast epithelium to drive breast cancer initiation/ progression.

Background Fat grafting to the reconstructed breast may result in the development of benign lesions on physical examination, prompting further investigation with imaging and biopsy. The aim of this study was to assess the influence of fat grafting on the incidence of imaging and biopsies after postmastectomy reconstruction. Methods Patients who underwent autologous or implant-based reconstruction following mastectomy from 2010 to 2018 were identified. Those receiving fat grafting as part of their reconstructive course were propensity matched 1:1 to those that did not with body mass index, reconstruction timing, and reconstruction type as covariates in a multivariable logistic regression model. Results A total of 186 patients were identified, yielding 93 propensity-matched pairs. Fat-grafted patients had higher incidences of palpable masses (38.0 percent versus 18.3 percent; p = 0.003) and postreconstruction imaging (47.3 percent versus 29.0 percent; p = 0.01), but no significant difference in the number of biopsies performed (11.8 percent versus 7.5 percent; p = 0.32). Imaging was predominately interpreted as normal (Breast Imaging-Reporting and Data System 1, 27.9 percent) or benign (Breast Imaging-Reporting and Data System 2, 48.8 percent), with fat necrosis being the most common finding [n = 20 (45.5 percent)]. No demographic, oncologic, reconstructive, or fat grafting-specific variables were predictive of receiving postreconstruction imaging on multivariate analysis. Fat grafting was not associated with decreased 5-year overall survival or locoregional recurrence-free survival. Conclusions Fat grafting to the reconstructed breast is associated with increased incidences of palpable masses and subsequent postreconstruction imaging with benign radiographic findings. Although the procedure is oncologically safe, both patients and providers should be aware that concerning physical examination findings can be benign sequelae of fat grafting and may lead to increased imaging after breast reconstruction.

Summary. The Resident Education Curriculum (REC) is one of the most widely recognized learning resources for plastic surgeons in training. The efforts that went into developing this program came from numerous individuals all driven by the same purpose – to create a lasting, up to date repository of all things plastic surgery related. As the program enters its 10th year of existence a closer look at the origins and evaluation is warranted.

Background Each year, millions of individuals develop scars secondary to surgery, trauma, and/or burns. Scar-specific patient-reported outcome measures to evaluate outcomes are needed. To address the gap in available measures, the SCAR-Q was developed following international guidelines for patient-reported outcome measure development. This study field tested the SCAR-Q and examined its psychometric properties. Methods Patients aged 8 years and older with a surgical, traumatic, and/or burn scar anywhere on their face or body were recruited between March of 2017 and April of 2018 at seven hospitals in four countries. Participants answered demographic and scar questions, the Fitzpatrick Skin Typing Questionnaire, the Patient and Observer Scar Assessment Scale (POSAS), and the SCAR-Q. Rasch measurement theory was used for the psychometric analysis. Cronbach's alpha, test-retest reliability, and concurrent validity were also examined. Results Consent was obtained from 773 patients, and 731 completed the study. Participants were aged 8 to 88 years, and 354 had surgical, 184 had burn, and 199 had traumatic scars. Analysis led to refinement of the SCAR-Q Appearance, Symptoms, and Psychosocial Impact scales. Reliability was high, with person separation index values of 0.91, 0.81, and 0.79; Cronbach alpha values of 0.96, 0.91, and 0.95; and intraclass correlation coefficient values of 0.92, 0.94, and 0.88, respectively. As predicted, correlations between POSAS scores and the Appearance and Symptom scales were higher than those between POSAS and Psychosocial Impact scale scores. Conclusions With increasing scar revisions, a scar-specific patient-reported outcome measure is needed to measure outcomes that matter to patients from their perspective. The SCAR-Q represents a rigorously developed, internationally applicable patient-reported outcome measure that can be used to evaluate scars in research, clinical care, and quality improvement initiatives.

Background Unplanned returns to the operating room (OR) may be necessary at times to salvage a compromised free flap. The aim of this study was to assess the influence of attending surgeon continuity on free flap outcomes following a return to the OR. Methods We retrospectively reviewed patients who underwent free flap reconstruction and experienced an unplanned return to the OR within 30 days from 2002 to 2017. Logistic regression modeling was used to determine factors that predict unplanned returns to the OR. Results Of the 1,177 patients were identified, 267 (22.5%) had an unplanned return to the OR. Of these, 69 (5.9%) patients experienced total flap loss. Overall, 216 take-back procedures were performed by the primary surgeons (80.2%), while 50 were performed by covering surgeons (18.8%). Flap loss occurred more frequently during a weekend procedure (p = 0.013). Additionally, when the take-back procedure was performed within 5 days of the original surgery by the primary as opposed to a covering surgeon, patients experienced lower estimated blood loss (75 vs. 150 cc, p = 0.04). Overall, there was a significantly lower incidence of flap loss when the take-back procedure was performed by the primary, as opposed to the covering, surgeon (20 vs. 47%, p = 0.0001). Conclusion Higher rates of flap loss occur when a covering surgeon performs a take-back procedure in comparison to the primary surgeon. It is important to ensure the availability of the primary surgeon in the first few postoperative days following free flap reconstruction. When transfer of care is necessary, photographic or video documentation of the microvascular anastomosis may be helpful in addition to a verbal sign out.

Breast cancer survival continues to improve, with women living longer after treatment. It is not well understood how long-term satisfaction and well-being differ following treatment or how types of reconstruction differ when compared to the norm.In a propensity-matched sample, the authors compared patient-reported outcomes in breast cancer patients at various time intervals from surgery with normative BREAST-Q data. All data were obtained using the Army of Women, an online community fostering breast cancer research. Breast cancer patients were stratified by surgical treatment and reconstruction type. Regression lines were estimated and differences in slope tested between cancer patients and noncancer controls.The authors compared normative (n = 922) and breast cancer (n = 4343) cohorts in a propensity-matched analysis. Among the breast cancer patients, 49.4 percent underwent lumpectomy, 17.0 percent underwent mastectomy, 21.7 percent underwent implant reconstruction, and 11.9 percent underwent autologous reconstruction. Median time since surgery was 4.7 years, with 21.1 percent more than 10 years after surgery. At the time of survey, breast cancer patients reported higher Satisfaction with Breasts and Psychosocial Well-being scores compared to noncancer controls (p0.01), with the cohorts undergoing lumpectomy and autologous reconstruction both reporting higher scores than the normative controls. After mastectomy, scores averaged lower than the noncancer controls, but improved over time. However, all breast cancer groups reported significantly lower Physical Well-being scores than the noncancer cohort (all p0.01).Breast cancer patients undergoing lumpectomy or autologous reconstruction reported higher psychosocial well-being compared to noncancer controls. These differences were influenced both by time since treatment and by choice of surgical procedure.

Wounds in the knee region are very common, secondary to trauma or orthopedic procedures. When hardware is associated with the wound, flap coverage is often needed. Additionally, because the knee is a very flexible joint, secondary healing and skin grafting are seldom adequate primary options for wound closure.

In the absence of extensive local trauma, edema, or radiation injury, local flaps may be a reasonable option for lower extremity reconstruction. When the defect is large and deep, a muscle flap may be required to obliterate the dead space, but when the defect is limited in its size and complexity, a local fasciocutaneous flap may suffice. These flaps can be elevated and positioned using a number of techniques described in this chapter.

Wounds that overlie the greater trochanter are common and at times require flap coverage. Two local flaps are well suited for these defects. The tensor fascia lata (TFL) flap and the anterolateral thigh (ALT) flap both have vascular origins from the lateral circumflex femoral artery and can be positioned proximally for hip coverage (Fig. 18.1).

Wounds in the upper knee region can occur after trauma, but they are typically associated with orthopedic procedures. They are often secondary to vascular procedures and may involve exposed prosthetics. The lower knee area is amenable to coverage with a gastrocnemius flap, but the upper knee is often out of the reach of this flap. In these circumstances, the reconstructive surgeon should be familiar with several other options (Fig. 19.1).

Wounds in the groin region are very common. They are often secondary to vascular procedures and may involve exposed prosthetics [1]. Additionally, some of these patients have previously compromised peripheral vascular systems, so it is necessary to have a knowledge of a variety of flaps and their associated vascular supply (Fig. 17.1). Likewise, wounds in the medial thigh, groin, and perineum are commonly related to oncologic resections. This chapter is specifically focused on groin wounds, but the same principles can apply to wounds of the medial thigh and some perineal wounds.

Wounds in the lower extremity may not be amenable to coverage with local tissue. In these instances, free tissue transfer is needed. Finding suitable recipient blood vessels for a microsurgical anastomosis is critical to success. Arterial inflow may be limited because of trauma or atherosclerotic disease. An angiogram can serve as a vascular roadmap for assessing recipient vessels. In general, when large vessels are used as recipient sites, a side branch of the main vessel can be used in an end-to-end fashion. If there are no available side branches, an end-to-side or end-to-end anastomosis to the main vessels may be performed. A thorough vascular exam must be done prior to sacrificing a large artery in the leg. In the lower leg, the tibial vessels are often used in an end-to-end or end-to-side fashion, depending on the overall vascular status.

The primary goal in foot reconstruction after trauma is to preserve function of the entire lower limb by helping to restore a stable weight-bearing surface that allows for painless ambulation. Additional considerations include ease of shoe fitting and aesthetic form of the reconstructed foot. When foot reconstruction is not possible or is complicated by failure or infection, the patient is at risk for undergoing a below-knee amputation.

Lower extremity reconstruction is unique in that there is high variability in tissue types and demands throughout the leg. Many soft tissue defects will involve concomitant bony injury, so an orthoplastic approach is required. Once it is determined that flap reconstruction is required, there are three main considerations

Background Breast implant placement is the most common method for postmastectomy reconstruction. For patients who develop complications associated with implant-based reconstruction, additional surgeries may be challenging. This study examined implant-based reconstruction failure in patients undergoing salvage with abdominal free tissue transfer. Methods We conducted an Institutional Review Board approved, multicenter retrospective study of patients with implant-based primary breast reconstruction followed by implant removal and subsequent abdominal free tissue transfer between 2006 and 2016. Patient demographics, treatment details, and complications were evaluated. Severity of implant failure was graded as either (1) not severe (delayed salvage reconstruction) or (2) severe (immediate salvage reconstruction). Results Between 2006 and 2016, 115 patients with 180 mastectomy defects underwent primary implant-based reconstruction with subsequent implant removal and abdominally based free tissue reconstruction. Of these, 68 were delayed and 47 were immediate salvage reconstruction. Factors leading to elective removal were capsular contracture, asymmetry, and implant malposition. Factors leading to obligatory removal were infection, delayed wound healing, and implant extrusion. Postmastectomy radiation was significantly associated with immediate salvage reconstruction (p Conclusion Our findings suggest that abdominal free tissue transfer remains a safe and effective salvage modality for implant-based breast reconstruction failure. Patients with severe implant failure were more likely to have received radiation. Surgeons should remain cognizant of this during care of patients.

Summary Background Intraoperative resident education is an integral mission of academic medical centers and serves as the basis for training the next generation of surgeons. The actual effort associated with teaching residents is unknown as it pertains to additional operative time. Using a large validated multi-institutional dataset, this study aims to quantify the effect of having a resident present in common plastic surgery procedures on operative time. Future directions for developing standardized methods to record and report teaching time are proposed, which can help inform prospective studies. Study design The 2006–2012 American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was queried to identify seven isolated plastic surgical procedures that were categorized based on resident involvement and supervision. Linear regression models were used to calculate the difference in operative time with respect to resident participation while controlling for patient and operative factors. Results Resident involvement was associated with longer operative times for muscle flap trunk procedures (53 min, 95% CI = [25, 80], p-value = 0.0002) and breast reconstruction procedures with a latissimus dorsi flap (55 min, 95% CI = [22, 88], p-value = 0.001). For six of the seven surgeries evaluated, resident involvement was associated with longer operative times, as compared to no resident involvement. Conclusion Resident involvement is associated with an increase in operative time for certain plastic surgery procedures. This finding underscores the need for a mechanism to quantify the time and effort that the attending surgeons allocate toward intraoperative resident education. Further study is also necessary to determine the causal impact on patient care.

BACKGROUND Weight gain is common in breast cancer patients and increases the risk of recurrence and mortality. The authors assessed the impact of autologous breast reconstruction on body mass index patterns after diagnosis in mastectomy patients. METHODS Women undergoing therapeutic mastectomy at the authors' institution from 2008 to 2010 were identified. Patients undergoing no breast reconstruction or autologous breast reconstruction were propensity-matched by age at diagnosis, baseline obesity, mastectomy laterality, and adjuvant therapies. Multivariable regression was used to estimate covariate associations with percentage body mass index change and percentage body mass index change greater than 5.0 percent at 1 to 4 years after diagnosis. RESULTS Of 524 total patients, 80 propensity-matched pairs were identified. In multivariable regression, women undergoing immediate autologous breast reconstruction had reduced body mass index changes after diagnosis, compared with nonreconstruction patients, at 1 year (β = -5.25 percent; p < 0.01), 2 years (β = -8.78 percent; p < 0.01), and 3 years (β = -7.21 percent; p < 0.01). After 4 years, all autologous reconstruction was predictive of reduced body mass index changes (β = -3.54 percent; p = 0.02). Higher body mass index increases were observed among women who were leaner at diagnosis (p < 0.01 at 1 year) and received chemotherapy (p = 0.02 at 3 years; p = 0.04 at 4 years). CONCLUSIONS Women undergoing autologous breast reconstruction gained less weight after diagnosis than nonreconstruction patients. Normal baseline body mass index and chemotherapy were predictive of greater body mass index increases. These findings may guide targeted weight management strategies in high-risk patients to maximize survival rates. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, III.

The American Society of Plastic Surgeons commissioned a multistakeholder Work Group to develop recommendations for autologous breast reconstruction with abdominal flaps. A systematic literature review was performed and a stringent appraisal process was used to rate the quality of relevant scientific research. The Work Group assigned to draft this guideline was unable to find evidence of superiority of one technique over the other (deep inferior epigastric perforator versus pedicled transverse rectus abdominis musculocutaneous flap) in autologous tissue reconstruction of the breast after mastectomy. Presently, based on the evidence reported here, the Work Group recommends that surgeons contemplating breast reconstruction on their next patient consider the following: the patient's preferences and risk factors, the setting in which the surgeon works (academic versus community practice), resources available, the evidence shown in this guideline, and, equally important, the surgeon's technical expertise. Although theoretical superiority of one technique may exist, this remains to be reported in the literature, and future methodologically robust studies are needed.

IBC has a unique presentation of diffuse tumor cell clusters called tumor emboli in the dermis of the chest wall that block lymph vessels causing a painful, erythematous, and edematous breast. Lack of effective therapeutic treatments has caused mortality rates of this cancer to reach 20%–30% in case of women with stage III–IV disease. Plasmonic nanoparticles, via photothermal ablation, are emerging as lead candidates in next-generation cancer treatment for site-specific cell death. Plasmonic gold nanostars (GNS) have an extremely large two-photon luminescence cross-section that allows real-time imaging through multiphoton microscopy, as well as superior photothermal conversion efficiency with highly concentrated heating due to its tip-enhanced plasmonic effect. To effectively study the use of GNS as a clinically plausible treatment of IBC, accurate three-dimensional (3D) preclinical models are needed. Here, we demonstrate a unique in vitro preclinical model that mimics the tumor emboli structures assumed by IBC in vivo using IBC cell lines SUM149 and SUM190. Furthermore, we demonstrate that GNS are endocytosed into multiple cancer cell lines irrespective of receptor status or drug resistance and that these nanoparticles penetrate the tumor embolic core in 3D culture, allowing effective photothermal ablation of the IBC tumor emboli. These results not only provide an avenue for optimizing the diagnostic and therapeutic application of GNS in the treatment of IBC but also support the continuous development of 3D in vitro models for investigating the efficacy of photothermal therapy as well as to further evaluate photothermal therapy in an IBC in vivo model.

Background Treatment algorithms for large soft tissue defects in lower extremity trauma are not clearly defined. The aim of this study is to determine if there are geographic or demographic differences in the management of open tibia fractures with soft tissue defects requiring either soft tissue reconstruction or amputation in the United States (US). Methods A retrospective analysis was performed on the Nationwide Inpatient Sample (NIS), 2000 to 2011. We evaluated flap and amputation rates in the open tibia fractures with soft tissue defects based on geographic and socioeconomic factors. Results From 2000 to 2011, there were 175,283 open tibia fractures in the US; 7.2% (n = 12,620) had a concomitant soft tissue defect requiring either flap or amputation. The overall flap rate was 73.2% (n = 9,235). When compared with the South at 68%, flap rates were highest in the West at 79% (adjusted odds ratio [AOR] = 2.06; 95% confidence interval [CI] = 1.49, 2.86; p Conclusions Reconstruction rates were significantly higher in three major US regions when compared with the South, urban hospitals in the West and Northeast, and the highest income quartile.

Introduction: Due to the aggressive nature of inflammatory breast cancer (IBC) and insensitive imaging techniques, patients diagnosed with IBC have a poor prognosis. IBC's unique ability to form emboli leads to rapid growth and distant invasion. New therapies aimed at disrupting the formation of tumor emboli are needed. Gold nanostars (GNS) are unique nanoparticles that can be imaged in real time with high sensitivity, and are rapidly endocytosed into cancer cells. Due to their sharp spikes, GNS exhibit plasmonic properties, which strongly enhance the electromagnetic field upon laser excitation. In addition to their use as highly intense and stable fluorescent labels, these nanoparticles can be photothermally activated to trigger cellular ablation. The use of GNS as an imaging and therapeutic modality for IBC should be investigated. Methods: IBC (SUM-149/SUM190), non-IBC (BT474M1/MD-MBA-231), and drug resistant isotype variant (rSUM-149) cell lines were incubated with GNS, stained with Hoechst33342, and imaged with multiphoton microscopy (MPM). The dose and time dependent effects of GNS on SUM-149 proliferation was assessed with MTT assays. Photothermal treatment was performed on GNS-labeled IBC, non-IBC, and drug resistant cancer cell lines. The effects of photothermal therapy on cell viability were assessed using fluorescein diacetate and propidium iodide. Using a tumor emboli model, SUM-149, rSUM-149, and SUM-190 tumor emboli were labeled with GNS on the 3rd day of embolic maturation. Emboli were sectioned, stained with H/E, and imaged with MPM to demonstrate the depth of GNS penetrance. The potential for photothermal ablation of the GNS-labeled tumor emboli was assessed using various laser intensities. Propidium iodide was used to examine emboli viability following treatment. Results: In all cell lines, GNS displayed rapid cellular uptake without nuclear involvement. MTT assay showed that GNS concentrations of 0.15 and 0.20 nM caused decreases in cell proliferation at 6 and 12 hours. Proliferative capacity was unaltered at 24 hours for all concentrations, however this may be due to spectrophotometric interference with high intracellular GNS concentrations. Live/dead staining confirmed effective photothermal treatment in all cultures with a clear zone of cellular death. For tumor emboli studies, GNS allowed bright fluorescent monitoring of tumor emboli using MPM, and cross sectional imaging demonstrated GNS penetrance into the embolic core. Photothermal ablation of GNS-labeled tumor emboli was successfully demonstrated following laser irradiation. Cell death was confirmed with propidium iodide. Conclusion: Gold nanostars provide a highly fluorescent intracellular label for cancer cell lines, and tumor emboli without significantly altering cell proliferation. Furthermore, the inherent optical properties of the GNS allows for a combined therapeutic application following phototoactivation. This is the first study to demonstrate the nanothernostic application of GNS in IBC tumor emboli. Prior studies have shown the effectiveness of photothermal ablation in in vivo sarcoma models; we are currently extending our studies to an IBC mouse model.
