One-Stage Deep Inferior Epigastric Perforator Flap Salvage of Infected Tissue Expanders.

BACKGROUND: Tissue expander-based breast reconstruction is associated with high rates of infectious complications, often leading to tissue expander explants and delays in receipt of definitive breast reconstruction and adjuvant therapy. In this study, we describe a single-stage technique where deep inferior epigastric artery perforator (DIEP) flaps are used to salvage actively infected tissue expanders among patients originally planning for free flap reconstruction. METHODS: In this technique, patients with tissue expander infections without systemic illness are maintained on oral antibiotics until the day of their DIEP flap surgery, at which time tissue expander explant is performed in conjunction with aggressive attempt at total capsulectomy and immediate DIEP flap reconstruction. Patients are maintained on 1-2 weeks of oral antibiotics tailored to culture data. Patients undergoing this immediate salvage protocol were retrospectively reviewed, and complications and length of stay were assessed. RESULTS: In a retrospective series, a total of six consecutive patients with culture-proven tissue expander infections underwent tissue expander removal and DIEP flap reconstruction in a single stage and were maintained on 7-14 days of oral antibiotics postoperatively. Within this cohort, no surgical site infections, microvascular complications, partial flap losses, reoperations, or returns to the operating room were noted within a 90-day period. CONCLUSIONS: Among a select cohort of patients, actively infected tissue expanders may be salvaged with free flap breast reconstruction in a single surgery with a low incidence of postoperative complications. Prospective studies are needed to evaluate the influence of this treatment strategy on costs, number of surgeries, and dissatisfaction after staged breast reconstruction complicated by tissue expander infections.

A Multi-institutional Analysis of a Textbook Outcome Among Patients Undergoing Microvascular Breast Reconstruction.

BACKGROUND: Individual outcomes may not accurately reflect the quality of perioperative care. Textbook outcomes (TOs) are composite metrics that provide a comprehensive evaluation of hospital performance and surgical quality. This study aimed to investigate the prevalence and predictors of TOs in a multi-institutional cohort of patients who underwent breast reconstruction with deep inferior epigastric artery perforator flaps. METHODS: For autologous reconstruction, a TO was previously defined as a procedure without intraoperative complications, reoperation, infection requiring intravenous antibiotics, readmission, mortality, systemic complications, operative duration ≤12 hours for bilateral and ≤10 hours for unilateral/stacked reconstruction, and length of stay (LOS) ≤5 days. We investigated associations between patient-level factors and achieving a TO using multivariable regression analysis. RESULTS: Of 1000 patients, most (73.2%) met a TO. The most common reasons for deviation from a TO were reoperation (9.6%), prolonged operative time (9.5%), and prolonged LOS (9.2%). On univariate analysis, tobacco use, obesity, widowed/divorced marital status, and contralateral prophylactic mastectomy or bilateral reconstruction were associated with a lower likelihood of TOs (P < 0.05). After adjustment, bilateral prophylactic mastectomy (odds ratio [OR], 5.71; P = 0.029) and hormonal therapy (OR, 1.53; P = 0.050) were associated with a higher likelihood of TOs; higher body mass index (OR, 0.91; P = <0.001) was associated with a lower likelihood. CONCLUSION: Approximately 30% of patients did not achieve a TO, and the likelihood of achieving a TO was influenced by patient and procedural factors. Future studies should investigate how this metric may be used to evaluate patient and hospital-level performance to improve the quality of care in reconstructive surgery.

Efficacy of Prophylactic Postoperative Antibiotics in Tissue Expander-Based Breast Reconstruction: A Propensity Score-Matched Analysis.

BACKGROUND: Conflicting evidence exists regarding the utility of prophylactic postoperative antibiotics in tissue expander (TE)-based breast reconstruction. This study evaluated the risk of surgical-site infection between patients receiving 24 hours of perioperative antibiotics alone versus prolonged postoperative antibiotics within a propensity score-matched cohort. METHODS: Patients undergoing TE-based breast reconstruction receiving 24 hours of perioperative antibiotics alone were propensity score-matched 1:3 to patients receiving postoperative antibiotics based on demographics, comorbidities, and treatment factors. Incidence of surgical-site infection was compared based on duration of antibiotic prophylaxis. RESULTS: Of a total of 431 patients undergoing TE-based breast reconstruction, postoperative antibiotics were prescribed in 77.2%. Within this cohort, 348 were included for propensity matching (no antibiotics, 87 patients; antibiotics, 261 patients). After propensity score matching, there was no significant difference in incidence of infection requiring intravenous (no antibiotics, 6.9%; antibiotics, 4.6%; P = 0.35) or oral antibiotics (no antibiotics, 11.5%; antibiotics, 16.1%; P = 0.16). In addition, rates of unplanned reoperation ( P = 0.88) and 30-day readmission ( P = 0.19) were similar. After multivariate adjustment, prescription of postoperative antibiotics was not associated with a reduction in surgical-site infection (OR, 0.5; 95% CI, -0.3 to 1.3; P = 0.23). CONCLUSIONS: Within a propensity score-matched cohort accounting for patient comorbidities and receipt of adjuvant therapies, prescription of postoperative antibiotics after TE-based breast reconstruction conferred no improvement in rates of TE infection, reoperation, or unplanned health care use. These data underscore the need for multicenter randomized trials on the utility of antibiotic prophylaxis in TE-based breast reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Air or Saline? A Propensity Score-Matched Analysis on the Effect of Tissue Expander Fill on Complications in Immediate Breast Reconstruction.

BACKGROUND: Tissue expander fill medium and volume have implications for the pressure exerted on mastectomy skin flaps. This study evaluated the influence of initial fill medium (air vs. saline) on complications in immediate breast reconstruction within a propensity score-matched cohort. PATIENTS AND METHODS: Patients undergoing immediate tissue expander-based breast reconstruction with initial intraoperative fill with air were propensity score matched 1:2 to those with saline initial fill based on patient and tissue expander characteristics. Incidence of overall and ischemic complications were compared by fill medium (air vs. saline). RESULTS: A total of 584 patients were included, including 130 (22.2%) with initial fill with air, 377 (64.6%) with initial fill with saline, and 77 (13.2%) with 0 cc of initial fill. After multivariate adjustment, higher intraoperative fill volume was associated with increased risk of mastectomy skin flap necrosis [regression coefficient (RC) 15.7; p = 0.049]. Propensity score matching was then conducted among 360 patients (Air: 120 patients vs. Saline: 240 patients). After propensity score matching, there were no significant differences in the incidences of mastectomy skin flap necrosis, extrusion, reoperation, or readmission between the air and saline cohorts (all p > 0.05). However, initial fill with air was associated with lower incidence of infection requiring oral antibiotics (p = 0.003), seroma (p = 0.004), and nipple necrosis (p = 0.03). CONCLUSIONS: Within a propensity score-matched cohort, initial fill with air was associated with a lower incidence of complications, including ischemic complications after nipple-sparing mastectomy. Initial fill with air and lower fill volumes may be strategies to reducing risk of ischemic complications among high-risk patients.

Textbook outcomes in DIEP flap breast reconstruction: a Delphi study to establish consensus.

PURPOSE: Composite measures, like textbook outcomes, may be superior to individual metrics when assessing hospital performance and quality of care. This study utilized a Delphi process to define a textbook outcome in DIEP flap breast reconstruction. METHODS: A two-round Delphi survey defined: (1) A textbook outcome, (2) Exclusion criteria for a study population, and (3) Respondent opinion regarding textbook outcomes. An a priori threshold of ≥ 70% agreement among respondents established consensus among the tested statements. RESULTS: Out of 85 invitees, 48 responded in the first round and 41 in the second. A textbook outcome was defined as one that meets the following within 90 days: (1) No intraoperative complications, (2) Operative duration ≤ 12 h for bilateral and ≤ 10 h for unilateral/stacked reconstruction, (3) No post-surgical complications requiring re-operation, (4) No surgical site infection requiring IV antibiotics, (5) No readmission, (6) No mortality, (7) No systemic complications, and (8) Length of stay < 5 days. Exclusion criteria for medical and surgical characteristics (e.g., BMI > 40, HgbA1c > 7) and case-volume cut-offs for providers (≥ 21) and institutions (≥ 44) were defined. Most agreed that textbook outcomes should be defined for complex plastic surgery procedures (75%) and utilized to gauge hospital performance for microsurgical breast reconstruction (77%). CONCLUSION: This Delphi study identified (1) Key elements of a textbook outcome for DIEP flap breast reconstruction, (2) Exclusion criteria for future studies, and (3) Characterized surgeon opinions regarding the utility of textbook outcomes in serving as quality metric for breast reconstruction care.

Defining the Value of Breast Reconstruction Surgeons: Quantifying Clinical Encounter and Operative Volume at an Academic Center.

Despite growing rates of postmastectomy breast reconstruction, the time contribution of breast reconstruction surgeons in comprehensive breast cancer care is often poorly accounted for by hospital and healthcare systems. This study models encounter volume and operative time utilization of breast reconstruction surgeons among patients undergoing postmastectomy breast reconstruction. Methods: All clinical encounters and operative time from a consecutive sample of breast cancer patients undergoing mastectomy and reconstruction were analyzed. Encounter volume and operative time utilization less than or equal to 4 years after diagnosis were modeled over time. Results: A total of 5057 breast cancer encounters were analyzed. Mean (SD) clinical encounter volume was 45.9 (28.5) encounters per patient, with encounter volume varying by specialty [plastic surgery: 16.5; medical oncology: 15.9; breast surgery: 7.2; radiation oncology: 6.3 mean encounters]. Receipt of adjuvant radiation, neoadjuvant chemotherapy, and major complications during reconstruction predicted higher encounter volume. Mean (SD) operative time utilization was 702 (317) minutes per patient [plastic surgery: 547 (305); breast surgery: 155 (71) minutes]. While both encounter volume and operative time for radiation oncologists and breast surgeons, respectively, were concentrated in the first year after diagnosis, medical oncologists and plastic surgeons sustained high clinical and operative time utilization 3 years after breast cancer diagnosis. Conclusions: Encounter volume and operative time utilization with breast reconstruction surgeons persist 3 years after a breast cancer diagnosis and are tied to treatment characteristics and incidence of reconstruction complications. Institutional- and system-level resource allocation must account for the complex and lengthy duration of care inherent to breast reconstruction care.

Microvascular Breast Reconstruction in the Era of Value-Based Care: Use of a Cosurgeon Is Associated with Reduced Costs, Improved Outcomes, and Added Value.

BACKGROUND: Reducing complications while controlling costs is a central tenet of value-based health care. Bilateral microvascular breast reconstruction is a long operation with a relatively high complication rate. Using a two-surgeon team has been shown to improve safety in bilateral microvascular breast reconstruction; however, its impact on cost and efficiency has not been robustly studied. The authors hypothesized that a cosurgeon for bilateral microvascular breast reconstruction is safe, effective, and associated with reduced costs. METHODS: The authors retrospectively reviewed all patients who underwent bilateral microvascular breast reconstruction with either a single surgeon or surgeon/cosurgeon team over an 18-month period. Charges were converted to costs using the authors' institutional cost-to-charge ratio. Surgeon opportunity costs were estimated using time-driven activity-based costing. Propensity scoring controlled for baseline characteristics between the two groups. A locally weighted logistic regression model analyzed the cosurgeon's impact on outcomes and costs. RESULTS: The authors included 150 bilateral microvascular breast reconstructions (60 single-surgeon and 90 surgeon/cosurgeon reconstructions) with a median follow-up of 15 months. After matching, the presence of a cosurgeon was associated with a significantly reduced mean operative duration (change in operative duration, -107 minutes; p < 0.001) and cost (change in total cost, -$1101.50; p < 0.001), which was even more pronounced when surgeon/cosurgeon teams worked together frequently (change in operative duration, -132 minutes; change in total cost, -$1389; p = 0.007). The weighted logistic regression models identified that a cosurgeon was protective against breast-site complications and trended toward reduced overall and major complication rates. CONCLUSION: The practice of using a of cosurgeon appears to be associated with reduced costs and improved outcomes, thereby potentially adding value to bilateral microvascular breast reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

A Mobile Extracorporeal Extremity Salvage System for Replantation and Transplantation.

BACKGROUND: Traumatic amputation is the second leading cause of limb loss in the United States. The preferred treatment is salvage and replantation of the amputated limb, whenever possible, and allotransplantation is a novel procedure whereby healthy limbs are procured from deceased organ donors and transplanted into the amputee recipient. A major restriction for both procedures is the irrecoverable muscle damage occurring due to ischemia. We investigated the feasibility of using a novel lightweight, mobile perfusion device specifically designed to perfuse amputated porcine limbs with an acellular perfusion solution to delay ischemic muscle damage prior to transplantation or replantation. METHODS: Bilateral hind limbs of Yorkshire pigs were amputated; one of the limbs was preserved by perfusion in the mobile perfusion device, and the other by storage in ice slurry for 12 hours. RESULTS: Five sets of bilateral limbs were preserved as described previously. A defined pressure of 30 mm Hg was reliably maintained in the arterial system without loss of flow. Comparison of the perfusate composition before and after limb passage revealed significant differences. Muscle biopsies showed a consistent progression of clusters of hypoxic cells in the control limbs with time. Similar changes could not be observed in the perfused tissue. CONCLUSIONS: We have designed and built a small, mobile perfusion device that is operational and that more closely mimics the normal physiological environment when compared with the current standard of preservation in ice slurry. This project may have far-reaching implications for the treatment of limb loss through replantation and transplantation.

Functional Outcomes after Bilateral Hand Transplantation: A 3.5-Year Comprehensive Follow-Up.

BACKGROUND: Since the first successful hand transplantation in 1998, 72 patients have been operated on for unilateral/bilateral hand transplantation across 13 countries. There have been multiple studies evaluating the outcomes of hand transplantation; however, there is considerable variability among the outcome measures evaluated in these studies. METHODS: This article reports functional outcomes in a patient with bilateral hand transplants at a mid-forearm level with serial follow-ups over 3.5 years. Different parameters used to study the functional outcomes include the Disabilities of the Arm, Shoulder, and Hand score, the Carroll test, the Hand Transplant Score System, the Short Form-36 Health Survey, and routine occupational therapy measures. Various task-oriented outcomes were also assigned to provide milestones to the recovery. RESULTS: The patient had a Disabilities of the Arm, Shoulder, and Hand score of 40, a Carroll test score of 48 (right) and 49 (left), and a Hand Transplant Score System score of 58 (right) and 57.5 (left) at 3.5-year follow-up. Interestingly, his objective scores did not change significantly during the follow-up, but he continued to function quite independently and is subjectively pleased with his outcomes. CONCLUSIONS: Multiple functional outcome measures provide an objective way to follow patients who have undergone hand transplantation. The authors propose a series of measures to elucidate subtleties in functional gains. However, use of this series in isolation may belie subjectively good results. They also propose a series of milestones in the recovery to give a better real-world explanation of progress. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, V.

Psychosocial Outcomes after Bilateral Hand Transplantation.

UNLABELLED: Since the first successful hand transplantation in 1998, there have been multiple reports about surgical technique, transplant survival, and immunosuppression. However, very limited published data exist on psychosocial outcomes following hand transplantation. METHODS: We report psychosocial outcomes in a patient with bilateral hand transplants at the midforearm level with serial follow-ups over 3.5 years. Different metrics used to study psychosocial outcomes included the following: SF-12, CES-D, Dyadic Adjustment Scale, Rosenberg SE, and EQ-5D. RESULT: Preoperatively, our patient did not have any evidence of depression (CES-D = 3), had a nonstressful relationship with his spouse (Dyadic Adjustment Scale = 100), and self-esteem was in the normal range (Rosenberg SE = 21). These metrics and his additional scales (SF-12 MCS, EQ-5D, and EQ-VAS) did not change appreciably and were within the normal range for the entire duration of 3.5-year follow-up at all different time points. CONCLUSION: With the increasing popularity of hand transplantation and the increasing awareness of the importance of psychosocial parameters in overall success, appropriate, comprehensive, and standardized measurements are important. These should be an integral part of patients' screening and follow-up.

Rehabilitation following hand transplantation.

BACKGROUND: Hand allotransplantation can restore motor, sensory and cosmetic functions to upper extremity amputees. Over 70 hand transplant operations have been performed worldwide, but there is little published regarding post-hand transplant rehabilitation. METHODS: The Brigham and Women's Hospital (BWH) Hand Transplantation Team's post-hand transplant rehabilitation protocol is presented here. The protocol must be modified to address each transplant recipient's unique needs. It builds on universally used modalities of hand rehabilitation such as splinting, edema and scar management, range of motion exercises, activities of daily living training, electrical stimulation, cognitive training and strengthening. RESULTS: The BWH hand transplant rehabilitation protocol consists of four phases with distinct goals, frequency, and modalities. (1) Pre-operative: functional assessments are completed and goals and expectations of transplantation are established. (2) Initial post-operative (post-operative weeks 1-2): hand protection, minimization of swelling, education, and discharge. (3) Intermediate (post-operative weeks 2-8): therapy aims to prevent and/or decrease scar adhesion, increase tensile strength, flexibility and function, and prevent joint contractures. (4) Late (from 8 weeks forward): maximization of function and strength, and transition to routine activities. The frequency of rehabilitation therapy decreases gradually from the initial to late phases. CONCLUSIONS: Rehabilitation therapy after hand transplantation follows a progressive increase in activity in parallel with wound healing and nerve regeneration. Careful documentation of progress and outcomes is essential to demonstrate the utility of interventions and to optimize therapy protocols.

Moist dressing coverage supports proliferation and migration of transplanted skin micrografts in full-thickness porcine wounds.

Transplantation of skin micrografts in a 1:100 ratio regenerate the epidermis of full-thickness wounds in pigs within 14 days in a wet environment. The aim of the current study was to combine micrografts and commercially available moist dressings. We hypothesized that micrografts regenerate the epidermis when covered with a moist dressing. 5cm×5cm and 10cm×10cm full-thickness wounds were created on the backs of pigs. Wounds were transplanted with 0.8mm×0.8mm micrografts created from a split-thickness skin graft in a 1:100 ratio. 5cm×5cm wounds were treated with wound chambers, moist dressings or dry gauze (non-transplanted control group). 10cm×10cm wounds were compared to non-transplanted wounds, both covered with moist dressings. Reepithelialization was assessed in biopsies from day 10, 14 and 18 post-transplantation. 5cm×5cm transplanted wounds covered with moist dressings showed 69.5±20.6% reepithelialization by day 14 and 90.5±10.4% by day 18, similar to wounds covered with a wound chamber (63.9±16.7 and 86.2±11.9%, respectively). 18 days post-transplantation, 10cm×10cm transplanted wounds covered with moist dressings showed 66.1±10.3% reepithelialization, whereas nontransplanted wounds covered with moist dressings were 40.6±6.6% reepithelialized. We conclude that micrografts combined with clinically available moist dressings regenerate the epidermis of full-thickness wounds.

Evolution of ethical debate on face transplantation.

BACKGROUND: Face transplantation can provide improved quality of life to severely disfigured individuals. The unique challenges of face transplantation prompted much ethical discussion even before the first clinical case. Many deemed it unethical, because of issues ranging from the need for potentially harmful immunosuppression to the potential transfer of identity. Over time, the ethical debate surrounding face transplantation has evolved. METHODS: In August of 2012, the authors performed a review of the scientific literature on the ethics of face transplantation, focusing on the evolution of the discussion from before to after the first clinical case in 2005. The authors conducted a primary search (73 peer-reviewed publications) in PubMed using combinations of the terms "ethics" and "face transplantation" and "opinions," and a secondary search (37 peer-reviewed publications) retrieving publications cited in some of the primary search findings. In total, the authors reviewed 110 articles. RESULTS: A series of 15 issues were addressed repeatedly throughout the reviewed articles. The authors observed an evolution of the general opinion regarding face transplantation: initially seen almost unanimously as an outlandish and morally objectionable procedure, it began to be accepted as a feasible and necessary treatment option for the most significant facial defects. CONCLUSION: With growing clinical experience globally, new ethical questions have arisen that must be addressed to move the field of face transplantation forward in an ethically sound manner.

Facial allotransplantation: a 3-year follow-up report.

INTRODUCTION: Long term follow-up of face transplant patients is fundamental to our understanding of risks and benefits of this procedure. Worldwide experience has shown that function improves gradually over time. METHODS: In April of 2009, a multidisciplinary team at Brigham and Women's Hospital performed face transplantation on a male patient to address a severe facial defect caused by high-voltage burns. Physical and occupational therapy was performed for the first six post-operative months. Close monitoring of the patient's functional recovery, immunosuppression, and quality of life was performed at set time points. RESULTS: Three years after face transplantation, the patient has recovered near-normal sensation. Along with satisfactory aesthetic results, his motor function continues to improve, aiding his speech, facial expressions, and social interaction. Furthermore, the patient reports continued improvements in quality of life. Infectious, metabolic, and immunologic complications have been successfully managed in a team approach. Immunosuppression doses have been effectively reduced, and steroid therapy was withdrawn before the end of the first postoperative year. CONCLUSIONS: The presented outcomes demonstrate the procedure's growing role in reconstructive surgery as teams continue to focus their efforts on further optimization of immunosuppression and surgical technique.

Face time: educating face transplant candidates.

OBJECTIVE: Face transplantation is the innovative application of microsurgery and immunology to restore appearance and function to those with severe facial disfigurements. Our group aims to establish a multidisciplinary education program that can facilitate informed consent and build a strong knowledge base in patients to enhance adherence to medication regimes, recovery, and quality of life. METHODS: We analyzed handbooks from our institution's solid organ transplant programs to identify topics applicable to face transplant patients. The team identified unique features of face transplantation that warrant comprehensive patient education. RESULTS: We created a 181-page handbook to provide subjects interested in pursuing transplantation with a written source of information on the process and team members and to address concerns they may have. While the handbook covers a wide range of topics, it is easy to understand and visually appealing. CONCLUSIONS: Face transplantation has many unique aspects that must be relayed to the patients pursuing this novel therapy. Since candidates lack third-party support groups and programs, the transplant team must provide an extensive educational component to enhance this complex process. PRACTICE IMPLICATIONS: As face transplantation continues to develop, programs must create sound education programs that address patients' needs and concerns to facilitate optimal care.

Current principles of facial allotransplantation: the Brigham and Women's Hospital Experience.

BACKGROUND: Facial allotransplantation is a revolutionary operation that has at last introduced the possibility of nearly normal facial restoration to patients afflicted by the most severe cases of facial disfigurement. METHODS: The facial transplantation team at Brigham and Women's Hospital evaluated more than 20 patients as potential face transplant recipients; of these, six became face transplant candidates and underwent full screening procedures. The team performed facial allotransplantations in four of these patients between April of 2009 and May of 2011. This is the largest clinical volume of facial transplant recipients in the United States to date. RESULTS: The authors have learned important lessons from each of these four unique cases and from the more than 20 patients that they have evaluated as potential face transplant recipients. The authors have translated lessons learned through direct experience into a set of fundamental surgical principles of the operation. CONCLUSIONS: The authors' surgical principles emphasize safety, technical feasibility, preservation of functional facial units, and return of motor and sensory function. This article describes each of these principles along with their rationale and, in some instances, illustrates their application.

Vascularized composite tissue allotransplantation--state of the art.

Vascularized composite tissue allotransplantation is a viable treatment option for injuries and defects that involve multiple layers of functional tissue. In the past 15 yr, more than 150 vascularized composite allotransplantation (VCA) surgeries have been reported for various anatomic locations including - but not limited to - trachea, larynx, abdominal wall, face, and upper and lower extremities. VCA can achieve a level of esthetic and functional restoration that is currently unattainable using conventional reconstructive techniques. Although the risks of lifelong immunosuppression continue to be an important factor when evaluating the benefits of VCA, reported short- and long-term outcomes have been excellent, thus far. Acute rejections are common in the early post-operative period, and immunosuppression-related side effects have been manageable. A multidisciplinary approach to the management of VCA has proven successful. Reports of long-term graft losses have been rare, while several factors may play a role in the pathophysiology of chronic graft deterioration in VCA. Alternative approaches to immunosuppression such as cellular therapies and immunomodulation hold promise, although their role is so far not defined. Experimental protocols for VCA are currently being explored. Moving forward, it will be exciting to see whether VCA-specific aspects of allorecognition and immune responses will be able to help facilitate tolerance induction.
