Aesthetic Surgery Fellowship at Akademikliniken Stockholm: Survey among Graduates.

BACKGROUND: Aesthetic Surgery is one of the most competitive fields of plastic surgery. Although there is a certain demand for highly educated surgeons in this field, training in cosmetic procedures remains challenging. Akademikliniken Stockholm offers a highly appreciated fellowship program for aesthetic plastic surgeons and trained more than 200 surgeons from all over the world. OBJECTIVES: The aim of the present work was to provide insights into this fellowship program, analyze what graduates have learned and if this had implications on their further professional orientation. METHODS: Participants of the Akademikliniken fellowship program, who graduated between 10/2008 and 10/2018 (n = 66) were invited to take part in an online survey which included 30 questions about general demographics and about experience before, during and after the fellowship. RESULTS: Thirty-four graduates participated in the survey (52%). Twenty-four graduates (71%) had been already specialists in plastic surgery before commencing the fellowship program. Mean length of fellowship was 7 months (range 3-24months). Numbers of aesthetic procedures performed by the applicants significantly increased after the fellowship, and moreover, the scope of daily clinical practice shifted toward aesthetics in almost all applicants. CONCLUSIONS: A well-designed dedicated aesthetic surgery fellowship can improve the lack of training, aesthetic surgeons have during their residency. Graduates of our fellowship program reported great improvements in confidence in performing aesthetic procedures and a benefit for their future career.

Patient-reported Outcomes Utilizing the Breast-Q Questionnaire After Breast Conserving Surgery With and Without Oncoplastic Breast Surgery: A Systematic Review and Meta-analysis.

Oncoplastic breast surgery (OBS) arose to decrease the deformity following breast conserving surgery (BCS) for breast cancer. In this meta-analysis (MA), we pool Breast-Q™ questionnaire data to compare quality of life (QOL) in breast cancer patients who received BCS alone or in combination with Level I or II oncoplastic breast surgery (BCS+OBS). All relevant databases were searched following the PRISMA and QUOROM guidelines. All prospective or retrospective studies with a BCS or BCS+OBS cohort that reported QOL as assessed with the Breast-Q™ questionnaire were eligible. Fifty-five studies (75 distinct patient cohorts; 11,186 patients) were included in the MA, with 12 studies reporting both pre- and postoperative values and eligible for a pairwise MA. The pairwise MA showed a significant postoperative improvement in the overall satisfaction with the breast (MD +8.0%, p=0.003) and in the psychosocial well-being (MD +9.2%, 3.5-14.8, p=0.001) of the entire cohort (BCS and BCS+OBS). A subgroup MA of proportions highlighted a superiority of BCS+OBS to BCS in terms of overall satisfaction with the breast (72.0%, 68.0-76.1, versus 62.9%, 58.3-67.5; p=0.02) and psychosocial well-being (78.9%, 71.5-86.4, versus 73.3%, 67.3-76.5, p=0.0001). A leave-one-out sensitivity analysis confirmed the results of the pairwise MA and the MA of proportions. Oncoplastic breast surgery effectively improves QoL based on the patient-reported outcomes assessed using the Breast-Q™ questionnaire. The improvements were associated with acceptable complication rates, further supporting the use of BCS followed by OBS where mastectomy would otherwise be necessary.

Enzymatic Debridement in Geriatric Burn Patients-A Reliable Option for Selective Eschar Removal.

The treatment of geriatric burn patients represents a major challenge in burn care. The objective of this study was to evaluate the efficacy of enzymatic debridement (ED) in geriatric burn patients. Adult patients who received ED for treatment of mixed pattern and full thickness burns (August 2017-October 2022) were included in this study and grouped in the younger (18-65 years) and geriatric (≥65 years) groups. Primary outcome was a necessity of surgery subsequent to ED. Both groups (patient characteristics, surgical and non-surgical treatment) were compared. Multiple logistic and linear regression models were used to identify the effect of age on the outcomes. A total of 169 patients were included (younger group: 135 patients, geriatric group: 34 patients). The burn size as indicated by %TBSA (24.2 ± 20.4% vs. 26.8 ± 17.1%, p = 0.499) was similar in both groups. The ASA (2.5 ± 1.1 vs. 3.4 ± 1.1, p < 0.001) and ABSI scores (6.1 ± 2.8 vs. 8.6 ± 2.3, p < 0.001) were significantly higher in the geriatric group. The %TBSA treated with ED (5.4 ± 5.0% vs. 4.4 ± 4.3%, p = 0.245) were similar in both groups. The necessity of additional surgical interventions (63.0 % vs. 58.8 %, p = 0.763) and the wound size debrided and grafted (2.9 ± 3.5% vs. 2.2 ± 2.1%; p = 0.301) were similar in both groups. Regression models yielded that age did not have an effect on efficacy of ED. We showed that ED is reliable and safe to use in geriatric patients. Age did not have a significant influence on the surgical outcomes of ED. In both groups, the size of the grafted area was reduced and, in many patients, surgery was avoided completely.

Stem Cell-Enriched Hybrid Breast Reconstruction Reduces Risk for Capsular Contracture in a Hybrid Breast Model.

BACKGROUND: Hybrid breast reconstruction (HBR) combines silicone implants with fat grafting to improve implant coverage, treating local tissue deficiencies and leading to a more natural breast appearance. Recent data also indicated less capsular contracture after HBR. The authors developed a novel technique and animal model of cell-assisted (CA) HBR to illuminate its effects on capsular contracture. METHODS: Animals received silicone implants in a dorsal submuscular pocket. Although animals of the HBR group received fat grafting around the implant without stem cell enrichment, rats of the CA-HBR1 and the CA-HBR2 groups received stem cell-enriched fat grafting with 2 × 10 6 and 4 × 10 6 adipose-derived stem cells immediately after implant insertion. On day 60, animals underwent sonography and elastography imaging and were euthanized, and outcome analysis was performed by means of histology, immunohistochemistry, chemical collagen quantification, and gene expression analysis. RESULTS: With this novel technique, long-term survival of adipose-derived stem cells within the implant pocket was demonstrated after 60 days after implant insertion. CA-HBR led to significantly reduced thickness and collagen density of capsular contractures. In addition, CA-HBR resulted in reduced fibrotic responses with less occurrence of collagen type I and transforming growth factor-ß in capsule tissue. Moreover, the addition of stem cells suppressed fibrotic and inflammatory responses on a genetic level with significant underexpression of collagen type I and transforming growth factor-ß1. CONCLUSIONS: With this new technique and animal model, the authors observed a preventive effect on capsular contracture substantiating the basis of clinical outcomes of HBR. The authors propose that the addition of stem cells to HBR might booster its beneficial results. CLINICAL RELEVANCE STATEMENT: Stem cell-enriched fat grafting around silicone implants may reduce the risk for capsular contracture after silicone breast implantation. While fat grafting alone already shows beneficial effects, the addition of stem cells to the fat graft can potentiate this effect.

Effective or Harmful-Evaluation of Locally Applied Antibiotics on Adipose Tissue during Lipofilling to the Breast-An In Vitro Study.

Lipofilling is a frequently used and safe procedure for breast reconstruction. One of the most feared complications is soft tissue infection following lipofilling. Because of this, some surgeons propose the practice of rinsing fat grafts with antibiotics. This study investigates the effect of antibiotic rinses on fat grafts in an in vitro model. Adipocytes and stem cells were isolated from fat tissue harvested during 24 lipofilling procedures and incubated with different doses of clindamycin or cefazolin. Cell viability, metabolism, proliferation, and differentiation capacities were analyzed by gross morphology, fluorescence staining, -(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazoliumbromid (MTT-), and Glyceraldehyde 3 Phosphate Dehydrogenase (G3PD)-assay as well as reactive oxygen species (ROS)-assay. Cefazolin and clindamycin led to significant reduction of cell viability of adipocytes. High doses of both antibiotics led to a rupture of adipocytes with visible free lipid droplets. Cell metabolism was significantly decreased after incubation with both antibiotics. There was a significant increase in ROS production. Exposure to clindamycin and cefazolin led to morphological changes in stem cells in a dose- and time-dependent manner. Furthermore, differentiation potential was significantly reduced. Antibiotic susceptibility testing, however, showed that low concentrations of antibiotics effectively inhibited bacterial growth in contaminated fat grafts. This study confirms that rinsing fat grafts with clindamycin or cefazolin not only overly prevents infection but also has cytotoxic and metabolic effects on adipocytes. Therefore, based on these results, the routine clinical application in high doses cannot be recommended.

Patient-Reported Outcomes After Reduction Mammoplasty Using BREAST-Q: A Systematic Review and Meta-Analysis.

BACKGROUND: The BREAST-Q questionnaire reduction module is an established tool for outcomes after reduction mammoplasty. OBJECTIVES: This systematic review and meta-analysis assess key parameters affecting pre- and postoperative scores, with specific foci on patient characteristics and tissue resection weights. METHODS: This study was conducted per PRISMA guidelines. PUBMED (National Institutes of Health; Bethesda, MD), Google Scholar (Google; Mountain View, CA), and Web of Science (Clarivate Analytics; Philadelphia, PA) were searched. All studies published before August 1, 2021, were assessed for eligibility by 2 independent reviewers. Inclusion criteria were prospective or retrospective studies in 6 languages that reported quality of life after reduction mammoplasty employing the BREAST-Q questionnaire reduction module. Quality of included studies was assessed employing the Newcastle-Ottawa-Scale. Analysis was performed per Cochrane Collaboration and the Quality of Reporting of Meta-analyses guidelines. RESULTS: A total of 28 papers were included in the systematic review, 13 for preoperative meta-analysis, and 17 for postoperative meta-analysis. Postoperative scores in all 3 quality of life domains (psychosocial, physical, and sexual well-being) and satisfaction with breasts increased significantly after reduction mammoplasty compared with preoperative scores. Satisfaction with breasts showed the greatest improvement, from 22.9 to 73.0. Preoperative scores were lower than normative data, with improvement to comparable scores as the healthy population postoperatively. Improvements in BREAST-Q scores did not correlate with patient comorbidities, complication rates, or amount of breast tissue resected. CONCLUSIONS: Reduction mammoplasty provides marked improvement in BREAST-Q patient-reported quality of life as well established in literature. However, these improvements do not correlate with tissue resection weights, warranting further inquiry of insurance-defined resection requirements.

30-Day Postoperative Outcomes in Adults with Obstructive Sleep Apnea Undergoing Upper Airway Surgery.

Background: Obstructive sleep apnea (OSA) is a chronic disorder of the upper airway. OSA surgery has oftentimes been researched based on the outcomes of single-institutional facilities. We retrospectively analyzed a multi-institutional national database to investigate the outcomes of OSA surgery and identify risk factors for complications. Methods: We reviewed the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database (2008−2020) to identify patients who underwent OSA surgery. The postoperative outcomes of interest included 30-day surgical and medical complications, reoperation, readmission, and mortality. Additionally, we assessed risk-associated factors for complications, including comorbidities and preoperative blood values. Results: The study population included 4662 patients. Obesity (n = 2909; 63%) and hypertension (n = 1435; 31%) were the most frequent comorbidities. While two (0.04%) deaths were reported within the 30-day postoperative period, the total complication rate was 6.3% (n = 292). Increased BMI (p = 0.01), male sex (p = 0.03), history of diabetes (p = 0.002), hypertension requiring treatment (p = 0.03), inpatient setting (p < 0.0001), and American Society of Anesthesiology (ASA) physical status classification scores ≥ 4 (p < 0.0001) were identified as risk-associated factors for any postoperative complications. Increased alkaline phosphatase (ALP) was identified as a risk-associated factor for the occurrence of any complications (p = 0.02) and medical complications (p = 0.001). Conclusions: OSA surgery outcomes were analyzed at the national level, with complications shown to depend on AP levels, male gender, extreme BMI, and diabetes mellitus. While OSA surgery has demonstrated an overall positive safety profile, the implementation of these novel risk-associated variables into the perioperative workflow may further enhance patient care.

Oral doxycycline prevents skin-associated adverse effects induced by injectable collagenase in a rodent model of capsular contracture around silicone implants.

BACKGROUND: The collagenase of the bacterium Clostridium histolyticum (CCH) is already an established treatment for fibroproliferative diseases like M. Dupuytren and M. Peyronie Although results are comparable to surgical intervention, skin laceration is a severe and relevant side effect. Doxycycline (DOX) recently rose interest as an inhibitor of matrix-metalloproteinases alongside its capabilities of skin accumulation. It therefore might be a potential skin protective agent in the use of CCH. METHODS: For simulation of a fibroproliferative disease adjacent to the skin, we utilized a rodent model of capsular fibrosis involving silicone implants and subsequent fibrotic capsule formation. For in-vitro studies, fibrotic capsules were excised and incubated with 0.9 mg/ml CCH and four different doses of DOX. For in-vivo experiments, animals received 0.0, 0.3 or 0.9 mg/ml CCH injections into the fibrotic capsules with or without prior oral DOX administration. Outcome analysis included histology, immunohistochemistry, gene expression analysis, chemical collagen and DOX concentration measurements as well as µCT imaging. RESULTS: In-vitro, DOX showed a dose-dependent inhibition of CCH activity associated with increasing capsule thickness and collagen density and content. In-vivo, oral DOX administration did neither interfere with capsule formation nor in effectiveness of CCH dissolving fibrotic capsule tissue. However, skin thickness and especially collagen density was significantly higher compared to control groups. This led to a reduced rate of clinical skin lacerations after DOX administration. CONCLUSION: DOX inhibits CCH and accumulates in the skin. Thereby, DOX can effectively reduce skin laceration after CCH treatment.

The impact of previous surgery on scaphoid nonunion reconstruction: a retrospective study of 95 cases.

We retrospectively compared 64 scaphoid reconstructions in cases that had not undergone previous surgery with 31 cases in which previous surgery had been performed. The characteristics of the groups were similar except that there were more smokers in the group without previous surgery and a more frequent use of vascularized bone grafts in the group with previous surgery. At final follow-up, 66 and 65 months, respectively, after reconstruction, union incidence was 89% and 90%. In patients with previous surgery, grip strength was higher but not when expressed in percent of the contralateral hand. There were no differences in pinch strength, active wrist motion, functional scores, carpal height or scapholunate angle. We conclude that repeat surgery to the scaphoid did not seem to be a major risk factor for the overall outcomes, keeping in mind that a vascularized bone graft was more frequently used for secondary reconstructions.Level of evidence: III.

The modified 5-item frailty index is a predictor of perioperative risk in breast reconstruction: An analysis of 40,415 cases.

BACKGROUND: The aging population has presented surgeons with new challenges as they increasingly must operate on greater numbers of frail patients. The modified frailty index 5 (mFI-5) is a concise comorbidity-based scale that has been shown to accurately predict adverse surgical outcomes. In this study, we sought to evaluate the ability of the mFI-5 to predict the risk of postoperative outcomes in breast reconstruction patients. METHODS: Utilizing the 2015-2019 American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database, we identified 40,415 patients who underwent breast reconstruction, of which 29,562 were implant-based reconstructions and 10,853 were autologous breast reconstructions. Demographic and preoperative variables as well as 30-day postoperative outcomes, including mortality, operation duration, length of hospital stay, medical and surgical complications, and discharge destination, were extracted. RESULTS: Increases in the mFI score correlated with higher rates of reoperation (mFI≥3: 13.5% vs. mFI=0: 5.9%), unplanned readmission (mFI≥3: 10.8% vs. mFI=0: 3.6%), surgical (mFI≥3: 12.2% vs. mFI=0: 4.3%) and medical complications (mFI≥3: 6.8% vs. mFI=0: 1.2%), and lower rates of home discharge (mFI≥3: 96% vs. mFI=0: 99.5%). Multivariate analysis to control for confounders verified significantly higher rates of reoperation (OR=0.01, 95%CI 0.005-0.016), unplanned readmission (OR=0.009, 95%CI 0.005-0.014), and occurrence of surgical complications (OR=0.014, 95%CI 0.009-0.019) and medical complications (OR=0.005, 95%CI 0.002-0.008). Stratification by age showed that the mFI-5 was a stronger risk predictor in younger patients who are frail. Stratification by type of reconstruction showed that increased mFI scores significantly correlated with complications in both autologous and implant-based reconstruction, but the correlation was greater in autologous procedures. CONCLUSION: The mFI-5 is identified as a powerful risk predictor in breast reconstruction. The application of this easily accessible tool in the preoperative risk stratification of patients undergoing breast reconstruction can enhance treatment planning and support, optimizing patient counseling, informed consent, and decision-making.

Racial disparities in short-term outcomes after breast reduction surgery-A National Surgical Quality Improvement Project Analysis with 23,268 patients using Propensity Score Matching.

BACKGROUND: Evidence of widespread disparities in healthcare for racial and ethnic minorities is well documented. This study aims to evaluate differences in surgical outcomes after breast reduction surgery (BRS) according to patients' ethnicities. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database (2005-2018) was utilized to analyze two propensity score matched patient cohorts-White and non-White-that underwent BRS. Preoperative variables assessed included demographic data and comorbidities such as diabetes mellitus, hypertension, and obesity. Postoperative outcomes assessed were medical complications, minor and major surgical complications, as well as mortality. RESULTS: In total, 23268 patients underwent BRS and met the inclusion criteria. After propensity score matching, the two cohorts were matched with respect to these preoperative variables, and 7187 patients were included in each cohort of White and non-White patients (total 14374). After matching, overall 30-day major complications were not significantly different between White and non-White cohort (2.25% vs 2.14%, p=0.65). After accounting for differences in confounding variables at the patient and socioeconomic level, racial and ethnic minorities who underwent breast reduction were found to experience fewer minor surgical complications. The analysis of temporal trends identified an overall rise in the number of patients seeking BRS, with a higher increase noted in the non-White population. CONCLUSION: Overall, our findings are reassuring exemptions to prevalent racial and ethnic health inequalities and can serve as a positive example for adequate and fair provision of surgical care.

The Impact of Metabolic Syndrome on Microvascular Head and Neck Reconstruction: An ACS-NSQIP data analysis.

BACKGROUND: Metabolic syndrome (MetS) can predispose patients to poorer surgical outcomes. In this study, we sought to evaluate the impact of MetS on the postoperative outcomes of head and neck microvascular reconstruction. METHODS: Review of the 2015-2019 NSQIP database identified 5,323 cases of microvascular reconstruction, of which 3,809 were head and neck cases. Of the included patients, 184 had MetS and 3625 did not. The groups were compared in terms of demographics and comorbidities. Postoperative outcomes assessed included mortality, average operative time and length of hospital stay, surgical and medical complications, and nonhome discharge. RESULTS: The MetS group had higher rates of medical complications (p<0.0001), sepsis (p=0.02), septic shock (p=0.01), and skilled care-discharge (p=0.0004). Analysis by flap type revealed that MetS patients receiving free skin flaps experienced higher rates of organ space infection (p=0.02), sepsis (p<0.0001), and lower home-discharge (p=0.01). In the free muscle group, superficial incisional infection (p=0.04), UTI (p=0.02), and septic shock (p=0.01) were higher in MetS patients. Stratification by surgical site showed that the occurrence of sepsis was significantly higher in the patients receiving microvascular flap reconstruction of the larynx (p=0.04) or tongue(p=0.03). Stratification of the MetS patients according to treatment for diabetes showed that patients receiving insulin experienced a higher rate of superficial incisional infection (p=0.04). A multivariate analysis verified significantly higher rates of medical complications (p<0.0001), sepsis (p=0.03) and septic shock (p=0.01) in the MetS group. CONCLUSION: Patients with MetS undergoing head and neck microvascular reconstruction are at increased risk of postoperative medical complications, including sepsis and septic shock, and are more likely to be discharged to a skilled care facility. Surgical outcomes were found to depend on the type of flap and site of surgery.

Teaching Microsurgical Breast Reconstruction-A Retrospective Cohort Study.

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

The Impact of Digital Nerve Injury on the Outcome of Flexor Tendon Tenolysis: A Retrospective Case-Control Study.

BACKGROUND: Tenolysis is an established treatment for flexor tendon adhesions at the hand. Concomitant finger nerve injuries with incomplete reinnervation may negatively influence outcomes. This study investigates the impact of finger nerve injuries on outcomes of flexor tendon tenolysis. METHODS: A retrospective pair-matched study was conducted, including patients undergoing tenolysis for flexor tendon adhesion after primary repair of isolated superficial and deep flexor tendon injury and both finger nerves (test group [TG]). These were compared with patients (control group [CG]) with similar injuries without affection of nerves and pair-matched in age, zone of injury and follow-up. Patients' demographics, finger sensitivity, total active range of motion (TAM) before and after tenolysis and complications were retrieved. RESULTS: For both study groups, 10 patients each were included in this study. There were no significant differences regarding patients' demographics and follow-up. Mean follow-up was 37 (CG) and 41 (TG) months. Total active range of motion was preoperatively 81 ± 47° (CG) and 68 ± 54° (TG) and reached postoperatively 125 ± 57° (CG) and 79 ± 43° (TG). Hence, TAM improvement was significantly higher in patients without nerve damage (58 ± 16 vs 21 ± 11%; P > 0.05). Tendon ruptures occurred significantly more frequent in patients with nerve injury (n = 0.4 ± 0.52) compared with patients of the CG (n = 0; P < 0.05). CONCLUSIONS: This study shows that finger nerve injury with incomplete recovery after combined flexor tendon and nerve injuries of the finger negatively influences the outcomes of flexor tendon tenolysis.

The transverse musculocutaneous gracilis flap for autologous breast reconstruction: focus on donor site morbidity.

PURPOSE: The transverse musculocutaneous gracilis (TMG) flap is as a valuable alternative in autologous breast reconstruction. The purpose of this study was to evaluate the donor site morbidity and secondary refinement procedures after TMG flap breast reconstruction. METHODS: A retrospective study was conducted, including all patients who received TMG flap breast reconstructions, from January 2012 to August 2019. Primary outcomes were surgical site complications of the donor site and secondary refinement procedures carried out for aesthetic or reconstructive purposes for the medial thigh. Secondary outcomes of interest were lipofilling procedures for optimization of the reconstructed breasts. RESULTS: Ninety-nine patients received 159 TMG flaps for breast reconstruction. Patients' mean BMI was 23.5 (15.6-32.5) kg/m2. Bilateral breast reconstructions were performed in 60.6%. The mean flap volume was 330 (231-440) g. Surgical site complications occurred in 14.5% of the TMG donor sites and wound dehiscence was the most common complication (9.4%). Lymphedema occurred in 1.8% of the donor thighs. Aesthetic refinement procedures were performed in 25.2% on the donor thigh or contralateral thigh. Secondary lipofilling was performed in 54.1% of the reconstructed breasts and fat was harvested in only 11.9% from the legs. CONCLUSION: The TMG flap breast reconstruction combines low donor site morbidity with adequate volume for appealing breast results, particularly in slim-to-normal weight patients. However, patients should be informed about the likelihood of secondary refinement procedures on the donor site and the need of lipofilling to optimize the breast shape and volume.

The modified 5-item frailty index is a predictor of perioperative risk in head and neck microvascular reconstruction: An analysis of 3795 cases.

BACKGROUND: The modified frailty index 5 (mFI-5)-a scale based on the five variables diabetes, hypertension, chronic obstructive pulmonary disease, congestive heart failure, and functional dependency-has been shown to be a valid predictor of surgical outcomes. In this study we sought to evaluate the ability of the mFI-5 to predict the postoperative outcomes of head and neck microvascular reconstruction. METHODS: Review of the 2015-2019 American College of Surgeons, National Surgical Quality Improvement Program (ACS NSQIP) database identified 5323 cases of microvascular reconstruction, of which 3795 were head and neck cases that provided parameters necessary to calculate the mFI-5. The groups were compared in terms of demographics and comorbidities. Post-operative outcomes assessed included mortality, average operative time and length of hospital stay, surgical and medical complications, and non-home discharge. RESULTS: Increases in the mFI were associated with longer hospitalization periods (10.5 ± 7.5 days in mFI 0 vs 14.9 ± 15.4 in mFI ≥ 3; p < 0.0001) higher rates of mortality (1% in mFI 0 vs 3.1% in mFI ≥ 3; p = 0.02), reoperation (15.4% in mFI 0 vs 17.2% in mFI ≥ 3; p = 0.002) and unplanned readmission (7.6% in mFI 0 vs 18.8% in mFI ≥ 3; p = 0.001). Rates of any complications (p < 0.0001), as well as surgical (p < 0.002) and medical (p < 0.0001) complications specifically were higher with greater mFI scores. Higher mFI scores also predicted decreased home discharge (p < 0.0001). Differences remained significant on multivariate analysis and subgroup analysis by age. CONCLUSION: The mFI-5 is a significant predictor of risk in microvascular head and neck reconstruction. Subgroup analysis by age highlights that the tool can help identify younger patients who are frail and hence at risk. Through appropriate pre-operative identification of frail patients surgeons can prospectively modify their operative and discharge planning as well as post-operative support.

Management of Acute and Traumatic Wounds With Negative-Pressure Wound Therapy With Instillation and Dwell Time.

BACKGROUND: A promising and useful development of negative-pressure wound therapy (NPWT) is the addition of instillation and dwell time of topical wound solutions (NPWTi-d). Uses of NPWTi-d include acute and traumatic wounds, whereby wound closure may be facilitated via wound cleansing and promotion of granulation tissue formation. This systematic review summarizes publications on NPWTi-d in the treatment of acute and traumatic wounds. METHODS: A systematic review was performed analyzing articles from major clinical databases. Only clinical studies ≥10 patients reporting on the application of NPWTi-d in acute and traumatic wounds were included. RESULTS: One hundred ninety-two articles were retrieved, of which 10 articles met inclusion criteria. Of those, 2 were lesser-quality randomized controlled trials, comparative studies or prospective cohorts, 2 were retrospective studies, and 6 retrospective cohort studies. In total, included publications reported 109 patients with acute and traumatic wounds treated with NPWTi-d. Data from these studies indicated the potential for reduction in bacterial bioburden through wound cleansing and promotion of granulation tissue formation, thereby facilitating wound closure, reduced length of therapy and hospital time. However, for most publications, different wound causes and subsequently no isolated results for acute and traumatic wounds were reported. CONCLUSION: NPWTi-d has promise to be effective in facilitating wound closure and reducing the time for wound closure. The present systematic review demonstrates a relatively low level of evidence available to objectively support this effect. To underline these positive results, large prospective, randomized controlled trials are necessary to manifest the role of NPWTi-d in the daily clinical routine for this wound category.
