Clinical utility of the modified frailty index in predicting adverse outcomes in patients undergoing lower extremity free flap reconstruction.

BACKGROUND: Identifying at-risk patients for complications remains challenging in patients with chronic lower extremity (LE) wounds receiving free tissue transfer (FTT) for limb salvage. The modified-5 frailty index (mFI-5) has been utilized to predict postoperative complications, yet it has not been studied in this population. The aim of this study was to determine the utility of the mFI-5 in predicting adverse postoperative outcomes. METHODS: Patients ≥60 years, who underwent LE FTT reconstruction at a single institution from 2011 to 2022, were retrospectively reviewed. Patient characteristics, mFI-5, and postoperative outcomes were collected. Cohorts were divided by an mFI-5 score of <2 or ≥2. RESULTS: A total of 115 patients were identified, of which 71.3% (n = 82) were male, 64.3% (n = 74) had a mFI-5 score of ≥2, and 35.7% (n = 41) had a score <2. The average age and body mass index were 67.8 years and 28.7 kg/m2 , respectively. The higher mFI-5 cohort had lower baseline albumin levels (3.0 vs. 4.0 g/dL, p = .015) and higher hemoglobin A1c levels (7.4 vs. 5.8%, p < .001). The postoperative length of stay was longer in the higher mFI-5 cohort (18 vs. 13.4 days, p = .003). The overall flap success was 96.5% (n = 111), with no difference between cohorts (p = .129). Postoperative complications were comparable between cohorts (p = .294). At a mean follow-up of 19.8 months, eight patients (7.0%) underwent amputation, and 91.3% (n = 105) were ambulatory. CONCLUSION: High microsurgical success rates can be achieved in comorbid patients with high frailty indexes who undergo FTT for limb salvage. A multidisciplinary team approach may effectively mitigate negative outcomes in elderly, frail patients.

Lymphovenous Coupler-Assisted Bypass for Immediate Lymphatic Reconstruction.

BACKGROUND: Breast cancer-related lymphedema is the most common cause of lymphedema in the United States and occurs in up to 50% of individuals receiving axillary lymph node dissection (ALND). Lymphovenous bypass (LVB) at the time of ALND may prevent lymphedema, but long-term results and anastomotic patency are unclear. This study evaluates the feasibility and outcomes of performing immediate lymphatic reconstruction via coupler-assisted bypass (CAB). METHODS: This is a retrospective review of all patients undergoing prophylactic LVB following ALND at two tertiary care centers between 2018 and 2022. Patients were divided into cohorts based on whether they received the "standard" end-to-end (E-E) suturing or CAB technique. The primary outcome of interest was development of lymphedema. Quantitative and qualitative assessments for lymphedema were performed preoperatively and at 3, 6, 12, and 24 months postoperatively. RESULTS: Overall, 63 LVBs were performed, of which 24 lymphatics underwent immediate reconstruction via "CAB" and 39 lymphatics via "standard" end-to-end suture. Patient characteristics, including body mass index, and treatment characteristics, including radiation therapy, did not significantly differ between groups. CAB was associated with a greater mean number of lymphatics bypassed per vein (standard 1.7 vs. CAB 2.6, p = 0.0001) and bypass to larger veins (standard 1.2 vs. CAB 2.2 mm, p < 0.0001). At a median follow-up of 14.7 months, 9.1% (1/11) of individuals receiving CAB developed lymphedema. These rates were similar to those seen following standard bypass at 4.8% (1/21), although within a significantly shorter follow-up duration (standard 7.8 vs. CAB 14.7 months, p = 0.0170). CONCLUSION: The CAB technique is a viable, effective technical alternative to the standard LVB technique. This comparative study of techniques in prophylactic LVB suggests that CABs maintain long-term patency, possibly due to the ease of anastomosing several lymphatics to single large caliber veins while reducing the technical demands of the procedure.

Prognostic Predictors of Mortality in Male Breast Cancer: Outcomes in an Urban Population.

INTRODUCTION: Male breast cancer (MBC) accounts for 0.5% to 1% of all breast cancers diagnosed annually. The purpose of this study is to evaluate prognostic factors in MBC. METHODS: We performed a retrospective chart review of patients with MBC between 2010 and 2021. Demographics, comorbidities, cancer characteristics, recurrence, and mortality were collected. Cox proportional hazards regression model was used to determine prognostic factors. A Kaplan-Meier curve was used to plot survival probabilities. RESULTS: A total of 47 male patients were identified. The mean age at presentation was 64.1 y. Twenty eight (59.6%) patients were African American and 14 patients (29.8%) were Caucasian. Most patients had invasive ductal carcinoma (89.4%) and presented with T1 or T2 tumors (40.4% and 38.3%, respectively). Three patients (6.4%) had a recurrence and eight patients (17%) died. Using mortality as an end point, age (≥ 76.1 y) indicated a hazard ratio (HR) of 1.13 (P = 0.004), diabetes mellitus (HR = 5.45, P = 0.023), atrial fibrillation (HR = 8.0, P = 0.009), end-stage renal disease (HR 6.47, P = 0.023), Eastern Cooperative Oncology Group performance status of 3 (HR = 7.92, P = 0.024), poorly differentiated grade (HR = 7.21, P = 0.033), and metastatic disease (HR = 30.94, P = 0.015) had an increased risk of mortality. Overall survival at 3 y was 79.2%. CONCLUSIONS: Advanced age, diabetes mellitus, atrial fibrillation, end-stage renal disease, Eastern Cooperative Oncology Group score of 3, poorly differentiated tumors, and metastatic disease are unfavorable prognostic factors in MBC. Compared to female breast cancer, MBC showed poorer overall survival.

Outcomes of Immediate Multistaged Abdominal Wall Reconstruction of Infected Mesh: Predictors of Surgical Site Complications and Hernia Recurrence.

BACKGROUND: Mesh infection is one of the most devastating complications after ventral hernia repair. To date, no clear consensus exists on the optimal timing of definitive abdominal wall reconstruction (AWR) after excision of infected mesh. We evaluated outcomes of immediate multistaged AWR in patients with mesh infection. METHODS: We performed a retrospective review of patients with mesh infection who underwent immediate, multistaged AWR, which consisted of exploratory laparotomy with debridement and mesh explantation, followed by definitive AWR during the same admission. Primary outcomes included hernia recurrence and surgical site occurrences, defined as wound dehiscence, surgical site infection, hematoma, and seroma. RESULTS: Forty-seven patients with infected mesh were identified. At mean follow-up of 9.5 months, 5 patients (10.6%) experienced hernia recurrence. Higher body mass index (P = 0.006), bridge repair (P = 0.035), and postoperative surgical site infection (P = 0.005) were associated with hernia recurrence. CONCLUSION: Immediate multistaged AWR is an effective surgical approach in patients with infected mesh.

Long-Term Outcomes in Patients With Peripheral Arterial Disease Who Undergo Free Flap Reconstruction for Chronic Lower Extremity Wounds.

BACKGROUND: Free tissue transfer (FTT) is critical for limb salvage of chronic lower extremity (LE) wounds. In patients with peripheral arterial disease (PAD), FTT LE reconstruction can be challenging due to limited vessel selection for anastomosis. The study aims to evaluate our surgical and functional outcomes after FTT to LE in patients with PAD. METHODS: A retrospective review identified patients who underwent LE free flap reconstruction between 2011 and 2021. All patients underwent preoperative arteriogram and subsequent FTT. Patients were classified into PAD or non-PAD cohorts, based on the presence of LE arterial stenoses or occlusions identified on arteriogram. Primary outcomes included complications, flap success, need for post-FTT vascular reintervention, limb salvage, and ambulatory status. RESULTS: A total of 253 patients underwent FTT to LE, with 84 patients (33.2%) in the PAD cohort. Patients with PAD had a higher prevalence of diabetes (83.3% vs 39.1%, P < 0.001) and end-stage renal disease (8.3% vs 2.4%, P = 0.028). Osteomyelitis was more common in the PAD group (73.8% vs 55.0%, P = 0.004). Free tissue transfer donor sites and flap composition were similar between cohorts. At a mean follow-up of 21.1 months, limb salvage rates were similar between non-PAD and PAD cohorts (90.5% vs 84.5%, P = 0.158), with no significant differences in ambulatory status or mortality. Higher complication rates occurred in the PAD cohort (38.1% vs 20.7%, P = 0.003), of which partial flap necrosis was more prevalent in the PAD group (6.0% vs 0.6%, P = 0.016). There was no difference in flap success rates between groups (P = 0.430). More postflap angiograms were performed in the PAD group (29.8% vs 7.1%, P < 0.001), with repeat percutaneous endovascular intervention performed in 68.0% of the PAD group versus 33.3% of the non-PAD group (P < 0.001). CONCLUSIONS: This is the largest study to demonstrate excellent long-term limb salvage outcomes in patients with PAD who undergo FTT to LE. Percutaneous endovascular intervention and FTT are effective methods to achieve limb salvage in vasculopathic patients with chronic LE wounds.

A comparative analysis of fasciocutaneous versus muscle free flaps in peripheral vascular disease patients.

OBJECTIVE: Chronic lower extremity (LE) wounds are common in patients with peripheral vascular disease (PVD). Free tissue transfer (FTT) provides healthy soft tissue for wound coverage and additional blood supply to promote wound healing. Given previous studies demonstrate increased complications in LE fasciocutaneous flaps, it was hypothesized that low vascular resistance in muscle flaps may be more advantageous for wound healing in PVD patients. Therefore, this study compared outcomes in PVD patients undergoing LE reconstruction with fasciocutaneous versus muscle free flaps. METHODS: Retrospectively reviewed PVD patients undergoing FTT between 2011 and 2021. Patients were stratified into fasciocutaneous and muscle free flap groups. Primary outcomes included complications, flap success, post-reconstruction vascular interventions, limb salvage, and ambulatory status. RESULTS: One hundred thirteen patients with PVD were identified, of which 60.2% received fasciocutaneous (n = 68) and 39.8% received muscle flaps (n = 45). Forty-two patients (37.2%) underwent pre-flap endovascular interventions. Flap success rate was 98.2% (n = 111). Overall complication rate was 41.2% following fasciocutaneous flaps compared to 24.4% in muscle flaps (p = 0.067). Fasciocutaneous flaps had higher odds of ulceration requiring repeat angiogram within 1 year of reconstruction compared to muscle flaps (OR 3.4, 95% CI: 1.07-10.95, p = 0.047), and higher odds of requiring repeat angiogram overall (OR 3.4, 95% CI: 1.07-10.95, p = 0.047). No difference in requiring procedures in the operated limb within 1 year was observed (p = 0.155). At mean follow-up, there was no difference in limb salvage, ambulatory, and mortality rate between groups. CONCLUSION: This study demonstrates that fasciocutaneous flaps had higher postoperative complication rates and more commonly required repeat arteriograms following LE FTT reconstruction due to recurrent ulcerations, suggesting greater utility of muscle flaps for FTT reconstruction in PVD patients.

Comparison of Charlson Comorbidity Index and Modified 5-Factor Frailty Index as Clinical Risk Stratification Tools in Predicting Adverse Outcomes in Patients Undergoing Lower Extremity Free-Flap Reconstruction.

BACKGROUND: Free tissue transfer (FTT) reconstruction is associated with a high rate of limb salvage in patients with chronic lower extremity (LE) wounds. Studies have shown perioperative risk stratification tools (e.g., 5-factor modified frailty index [mFI-5] and Charlson comorbidity index [CCI]) to be useful in predicting adverse outcomes; however, no studies have compared them in patients undergoing LE reconstruction. The aim of this study is to compare the utility of mFI-5 and CCI in predicting postoperative morbidity in elderly patients receiving LE FTT reconstruction. METHODS: A retrospective review of patients aged 60 years or older who underwent LE FTT reconstruction from 2011 to 2022 was performed. Comorbidity burden was measured by two validated risk-stratification tools: mFI-5 and CCI. Primary outcomes included prolonged postoperative length of stay (LOS), defined as greater than 75th percentile of the cohort, postoperative complications, and eventual amputation. RESULTS: A total of 115 patients were identified. Median CCI and mFI-5 were 5 (interquartile range [IQR]: 4-6) and 2 (IQR: 1-3), respectively. Average postoperative LOS was 16.4 days. Twenty-nine patients (25.2%) experienced a postoperative complication, and eight patients (7%) required LE amputation at a mean follow-up of 19.8 months. Overall, flap success was 96.5% (n = 111), and limb salvage rate was 93% (n = 108). Increased CCI was found to be independently predictive of only eventual amputation (odds ratio: 1.59; p = 0.039), while mFI-5 was not predictive of prolonged postoperative LOS, flap complications, or eventual amputation. CONCLUSION: This is the first study to compare the utility of mFI-5 and CCI in predicting adverse outcomes in elderly patients undergoing LE FTT reconstruction. Our results demonstrate CCI to be a superior predictor of secondary amputation in this patient population and mFI-5 to have limited utility. Further investigation in a prospective multicenter cohort is warranted.

Amputation Acceptance: A Survey of Factors Influencing the Decision to Undergo Lower Extremity Amputation.

Accepting to undergo amputation is an arduous process often fraught with confusion, fear, and uncertainty. To assess how to best facilitate discussions with at-risk patients, we surveyed lower extremity amputees about their experiences surrounding this decision-making process. Patients who underwent lower extremity amputation at our institution from October 2020 to October 2021 were asked to complete a 5-item telephone survey assessing their decision to undergo amputation and postoperative satisfaction. Retrospective chart review of respondent demographics, comorbidities, operative details, and complications was conducted. Of 89 lower extremity amputees identified, 41 (46.07%) responded to the survey, with the majority undergoing below-knee amputations (n = 34, 82.93%). At a mean follow-up of 5.90 ± 3.45 months, 20 patients (48.78%) were ambulatory. Surveys were completed at a mean of 7.74 ± 4.03 months since amputation. Factors that helped patients decide to undergo amputation included discussions with doctors (n = 32, 78.05%) and concern for worsening health (n = 19, 46.34%). Deteriorating ability to walk (n = 18, 45.00%) was the most common concern prior to surgery. Recommendations by survey respondents to ease the decision-making process included speaking with amputees (n = 9. 22.50%), more discussions with doctors (n = 8, 20.00%), and access to mental health and social services (n = 2, 5.00%); however, many had no recommendations (n = 19, 47.50%), and most were pleased with their decision to undergo amputation (n = 38, 92.68%). Despite most patients primarily citing satisfaction with their decision to undergo lower extremity amputation, it is critical to consider factors that affect patient decisions and recommendations to improve this decision-making process.

A comparative analysis of males and females with breast cancer undergoing mastectomy using the American College of Surgeon's National Surgical Quality Improvement Project (NSQIP).

INTRODUCTION: There is a paucity of literature comparing the postoperative outcomes of males and females with breast cancer who undergo mastectomy. The aim of this study is to evaluate the comorbidities and 30-day post-mastectomy complication rates among males and females. METHODS: We performed a retrospective analysis of breast cancer patients who underwent mastectomy from 2014 to 2016 using the American College of Surgeon's National Surgical Quality Improvement Project database. Data including patient demographics, comorbidities, and 30-day surgical and medical complications were collected. Statistical analysis included Chi-square and Fisher's exact tests for categorical variables and Student T-tests for continuous variables. Statistical significance was defined as p < 0.05. RESULTS: A total of 15,167 patients were identified. There were 497 males (3.3%) and 14,670 females (96.7%). Age was significantly higher in females compared to males (63.5 vs. 57.6 years, p < 0.001). Body mass index (BMI) at time of surgery was also higher in males (30.0 vs. 29.3 kg/m2, p = 0.011). There was a higher prevalence of diabetes in males (20.1 vs. 16.5%, p = 0.032). Operative duration was significantly longer in females (114.9 vs. 95.0 min, p < 0.001). Median postoperative length of stay was also longer in females (1.2 vs. 0.8 days, p < 0.001). There were no significant differences in 30-day medical or surgical complication rates between the two sexes. CONCLUSION: Our findings suggest that differences in age, BMI, and comorbidities between males and females do not significantly impact 30-day medical or surgical complications following total mastectomy for breast cancer. Further research is warranted to identify perioperative risk factors that influence post-mastectomy complication rates. LEVEL OF EVIDENCE: 3 (Retrospective cohort study).

Postmastectomy Reconstruction in Male Breast Cancer.

Introduction: Less than 1% of all breast cancers are diagnosed in males. In females, postmastectomy breast reconstruction is associated with increased patient satisfaction. However, there is a paucity of literature describing reconstructive options for postmastectomy deformity in the male chest. The purpose of this systematic review was to evaluate postmastectomy reconstruction outcomes in males with breast cancer. Methods: A systematic review was performed in accordance with PRISMA guidelines. Ovid MEDLINE, Embase, Cochrane, and Web of Science were queried for records pertaining to the study question using medical subject heading (MeSH) terms such as "male breast cancer," "mastectomy," and "reconstruction." No limitations were placed on the year of publication, country of origin, or study size. Study characteristics and patient demographics were collected. Primary outcomes of interest included postoperative complications, recurrence rate, and mortality rate. Results: A total of 11 articles examining 29 male patients with breast cancer who underwent postmastectomy reconstruction were included for analysis. Literature was most commonly available in the form of case reports. The average age was 59.6 +/-11.4 years. Reconstruction methods included fat grafting (n = 1, 3.4%), silicone implants (n = 1, 3.4%), and autologous chest wall reconstruction with local flaps (n = 26, 89.7%). Postoperative complications occurred in two patients (6.8%), including partial nipple necrosis (n = 1) and hypertrophic scarring (n = 1). Of the studies reporting patient satisfaction, all patients were pleased with the aesthetic appearance of their chest. Conclusion: This systematic review revealed the limited availability of research regarding postmastectomy chest reconstruction in males with breast cancer. Nevertheless, the evidence available suggests that reconstruction can restore a patient's body image and, thus, should be regularly considered and discussed with male patients. Larger studies are warranted to further shed light on this population.

Free flap reconstruction of plantar weight-bearing heel defects: Long-term functional and patient-reported outcomes.

PURPOSE: Non-healing plantar weight-bearing heel ulcers are a challenging problem to treat. Free tissue transfer (FTT) reconstruction of the heel is an opportunity for limb salvage to preserve gait and ambulation. The aim of this study is to describe surgical and functional outcomes in patients who underwent FTT to treat chronic heel ulcers. METHODS: A retrospective review of patients who underwent FTT for plantar heel ulcers from 2011 to 2021 was conducted. Patient demographics, comorbidities, perioperative data, postoperative complications, and long-term outcomes were recorded. Primary outcomes included flap success, complications, postoperative ambulation, patient-reported outcome measures and limb salvage, with patients stratified into limb salvage or eventual amputation groups. RESULTS: Forty-four patients underwent 45 heel reconstructions. Average age and BMI were 57.3 years and 30.1 kg/m2 , respectively. Thirty-eight patients (86.4%) had calcaneal osteomyelitis, 35 patients (79.5%) had diabetes, and 18 patients (40.9%) had peripheral vascular disease (PVD). Immediate microsurgical success rate was 95.6%. At mean follow-up of 19.6 ± 20.9 months, overall limb salvage rate was 73.3% (n = 33). Preoperative albumin levels were higher in limb salvage group compared to the amputation group (3.0 vs. 2.4 g/dl, p = .018). Prior stroke history and hypoalbuminemia were significantly higher in the amputation group compared to limb salvage group (p = .012 and p = .018, respectively). Risk for eventual amputation was associated with PVD (OR 4.0, p = .053), hypoalbuminemia (OR 4.9, p = .020), and postoperative infection (OR 6.3, p = .013). Of the 12 amputations that occurred, the most common indication for amputation was infection (n = 8, 66.7%), which most often occurred at the original wound location (62.5%). At most recent follow-up, 90.7% of patients (n = 39) were ambulatory. CONCLUSION: FTT is an effective alternative to amputation in patients with chronic heel ulcers. Proper patient selection, preoperative optimization, and postoperative care are imperative to the success of this limb salvage procedure.

Intensive care unit versus floor admission following lower extremity free flap surgery: Is there a difference in outcomes?

BACKGROUND: Free tissue transfer (FTT) lower limb salvage requires costly multidisciplinary care. Traditionally, patients who undergo FTT reconstruction for lower extremity (LE) wounds were admitted to the intensive care unit (ICU) in the immediate postoperative period for close monitoring. During the COVID-19 pandemic, our practice shifted toward admitting FTT patients to the floor postoperatively instead of the ICU. The purpose of this study is to compare surgical outcomes in patients admitted to the floor versus ICU immediately following LE free flap reconstruction. METHODS: We retrospectively reviewed patients undergoing LE FTT reconstruction from 2011 to 2021. Flap monitoring consisted of an implantable Cook-Swartz Doppler probe for muscle flaps and ViOptix tissue oximetry for fasciocutaneous flaps; clinical exam and hand-held dopplers were not the primary flap monitoring techniques. Patients were divided into two groups depending on whether they went to the ICU or floor postoperatively. To ensure proper comparability between cohorts, we corrected for age, BMI and Charlson Comorbidity Index (CCI) using 1:2 propensity score matching (floor: ICU). Primary outcomes included early postoperative complications, flap takeback and salvage, flap success, and postoperative length of stay (LOS). RESULTS: A total of 252 patients were identified. Forty-five patients (17.9%) were admitted to the floor postoperatively and 207 patients (82.1%) to the ICU. Overall, microsurgical success rate was 97.2%, which was similar for floor and ICU patients. Flap takeback and salvage were similar between cohorts. Average postoperative LOS was significantly shorter in floor patients (15.7 vs. 19.1 days, p = 0.043). CONCLUSION: Our findings suggest that postoperative floor admission does not decrease flap success rates and should be considered in patients who undergo FTT to LE reconstruction and are otherwise stable. In the ongoing era of health care cost containment, microsurgery centers should consider appropriate floor training to allow medically stable free flap patients to avoid an ICU stay.

Propeller Perforator Flaps Used for Hand and Digit Reconstruction: A Systematic Review.

Background: Propeller perforator flaps (PPFs) have increased in popularity due to the freedom in design and ability to cover a variety of defects without sacrificing the major vessels. Present reports of PPFs for upper limb reconstruction have not provided guidance for hand reconstruction, specifically. This study aims to review the current literature and evaluate techniques for use of PPFs in hand reconstruction. Methods: A comprehensive literature review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for articles published from 1991 to 2021. The database search was queried for records using appropriate Medical Subject Headings (MeSH) terms. Studies reporting PPFs were limited to English language and excluded lower extremity or upper extremity reconstruction not specific to defects in the hand or digits. Study characteristics, patient demographics, indications, preoperative testing, flap characteristics, flap survival, and complication rates were collected. Results: Out of the initial 1,348 citations yielded, 71 underwent full-text review. Ultimately, 25 unique citations were included encompassing 12 retrospective reviews (48%), 3 prospective cohort studies (10%), and 10 case series (40%). In review, 525 patients underwent reconstruction with a total of 613 propeller flaps performed to repair defects of the hand, digits, or both with use of 18 unique flap types. Overall flap survival was 97.8%. Acute wounds accounted for 72.9% of performed reconstructions. The mean flap coverage was 14.7 cm2. Complications occurred in 19.8% of cases, with venous congestion and partial flap necrosis occurring in 5.5 and 6.5% of cases, respectively, leading to a flap failure rate of 2.1%. Conclusion: PPFs are a reliable option for hand or digital reconstruction, allowing surgeons to cover a variety of defects without sacrificing local vasculature. Despite nearly a 20% reported complication rate, nearly all flaps with venous congestion and partial flap necrosis included in these articles resolved without the need for secondary intervention, retaining an excellent overall flap survival.

The Use of Flap Techniques to Preserve Limb Length in Patients with Transmetatarsal Amputations.

BACKGROUND: Chronic lower extremity wounds affect up to 13% of the US population. Transmetatarsal amputation (TMA) is frequently performed in patients with chronic forefoot wounds. TMA allows limb salvage and preserves functional gait, without need for prosthesis. Traditionally, when tension-free primary closure is not possible, a higher-level amputation is performed. This is the first series to evaluate the outcomes of local and free flap coverage of TMA stumps in patients with chronic foot wounds. METHODS: A retrospective cohort of patients who underwent TMA with flap coverage from 2015 through 2021 was reviewed. Primary outcomes included flap success, early postoperative complications, and long-term outcomes (limb salvage and ambulatory status). Patient-reported outcome measures using the Lower Extremity Functional Scale (LEFS) were also collected. RESULTS: Fifty patients underwent 51 flap reconstructions (26 local, 25 free flap) after TMA. Average age and body mass index were 58.5 years and 29.8 kg/m 2 , respectively. Comorbidities included diabetes [ n = 43 (86%)] and peripheral vascular disease [ n = 37 (74%)]. Flap success rate was 100%. At a mean follow-up of 24.8 months (range, 0.7 to 95.7 months), the limb salvage rate was 86.3% ( n = 44). Forty-four patients (88%) were ambulatory. The LEFS survey was completed by 24 surviving patients (54.5%). Mean LEFS score was 46.6 ± 13.9, correlating with 58.2% ± 17.4% of maximal function. CONCLUSIONS: Local and free flap reconstruction after TMA are viable methods of soft-tissue coverage for limb salvage. Applying plastic surgery flap techniques for TMA stump coverage allows for preservation of increased foot length and ambulation without a prosthesis. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Age is just a number: The role of advanced age in predicting complications following ventral hernia repair with component separation.

BACKGROUND: While advanced age is often considered a risk factor for complications following abdominal surgery, its impact on outcomes after complex open ventral hernia repair (VHR) with component separation technique (CST) remains unclear. METHODS: A single-center retrospective review of patients who VHR with CST from November 2008 to January 2022 was performed and cohorts were stratified by presence of advanced age (≥60 years). RESULTS: Of 219 patients who underwent VHR with CST, 114 patients (52.1 â€‹%) were aged ≥60 years. Multivariate analysis demonstrated BMI to be an independent predictor for any complication (OR 1.1, p â€‹= â€‹0.002) and COPD was positively associated with seroma development (OR 20.1, p â€‹= â€‹0.012). Advanced age did not independently predict postoperative outcomes, including hernia recurrence (OR 0.8, p â€‹= â€‹0.766). CONCLUSIONS: VHR with CST is generally safe to perform in patients of advanced age. Every patient's comorbidity profile should be thoroughly assessed preoperatively for risk stratification regardless of age.

Perioperative misgendering experiences in patients undergoing gender-affirming surgery: a call for a gender-inclusive healthcare environment.

Background: Transgender individuals have long experienced discrimination and exclusion from medicine. Misgendering occurs when an individual is referred to using a gender or address incongruent with their identity. We evaluated the incidence of misgendering throughout the perioperative experience for patients undergoing gender-affirming surgery (GAS). Methods: Patients diagnosed with gender dysphoria who previously received GAS by the senior author were contacted to complete an IRB-approved survey to evaluate instances of misgendering while in the hospital for GAS. Study results were summarized using descriptive statistics. Results: Of 471 patients contacted, 182 completed the survey (38.6%). The most cited gender identity was transfemale (28.0%). Most patients reported respect for their gender identity (60.4%) and name (76.8%) during their perioperative experience. Twenty-two percent cited triggering experiences, and 15.4% reported interactions with healthcare employees causing them to reach out to a support system. Misgendering most commonly included incorrect use of patients' preferred names and/or pronouns (n = 50, 86.2%), most commonly at surgical check-in (n = 10, 45.5%). Recommendations to improve feelings of gender congruence during patients' stay included updated names and gender identities in electronic medical records (80.8%), and names and pronouns listed on curtains and doors (52.3%) and name tags (51.5%). Conclusions: Until now, the exact incidence of misgendering among patients seeking GAS have not been well established. Despite high levels of satisfaction, a large proportion still reported serious instances of misgendering. Improvements must be made to the perioperative experience to reduce misgendering and provide support and comfort during the sensitive period surrounding patients' gender transition.Level of evidence: Not gradable.

Risk-Stratified Anticoagulation Protocol Increases Success of Lower Extremity Free Tissue Transfer in the Setting of Thrombophilia.

BACKGROUND: Optimal perioperative thromboprophylaxis is crucial to avoid flap thrombosis and achieve high rates of microsurgical success. At the authors' institution, implementation of a risk-stratified anticoagulation (AC) protocol preliminarily showed a reduction in postoperative thrombotic events and flap loss. The authors present an updated analysis of surgical outcomes using risk-stratified AC in thrombophilic patients who underwent free tissue transfer (FTT) reconstruction for nontraumatic lower extremity (LE) wounds. METHODS: The authors retrospectively reviewed patients who underwent FTT to an LE from 2012 to 2021. Their risk-stratification AC protocol was implemented in July of 2015. Low-risk and moderate-risk patients received subcutaneous heparin. High-risk patients received heparin infusion titrated to a goal partial thromboplastin time of 50 to 70 seconds. Before July of 2015, nonstratified patients were treated with either subcutaneous heparin or low-dose heparin infusion (500 U/hour). Patients were divided into two cohorts (nonstratified and risk-stratified) based on date of FTT reconstruction. Primary outcomes included rates of postoperative complications, flap salvage, and flap success. RESULTS: Two hundred nineteen hypercoagulable patients who underwent FTT to an LE were treated with nonstratified ( n = 26) or risk-stratified ( n = 193) thromboprophylaxis. The overall flap success rate was 96.8% ( n = 212). Flap loss was lower among risk-stratified patients (1.6% versus 15.4%; P = 0.004), which paralleled a significant reduction in postoperative thrombotic events (2.6% versus 15.4%; P = 0.013). Flap salvage was accomplished more often in the risk-stratified cohort (80% versus 0%; P = 0.048). Intraoperative anastomotic revision (OR, 6.10; P = 0.035) and nonrisk stratification (OR, 9.50; P = 0.006) were independently associated with flap failure. CONCLUSIONS: Hypercoagulability can significantly affect microsurgical outcomes. Implementation of a risk-stratified AC protocol can significantly improve flap outcomes. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

A retrospective cohort study comparing reconstructive techniques and outcomes in post-mastectomy triple negative breast cancer patients.

Background: Up to 42% of all breast cancer patients undergo post-mastectomy reconstruction, however reconstructive techniques have not been widely studied in patients with triple negative breast cancer (TNBC). Reconstructive complications may delay adjuvant treatments; in TNBC, which inherently carries an increased risk of locoregional recurrence, this can greatly affect oncological outcomes. Therefore, we evaluate factors influencing choice of reconstructive techniques following mastectomy in TNBC patients and assess operative and oncologic safety outcomes. Methods: A single institution retrospective chart review identified TNBC patients who underwent post-mastectomy reconstruction between 2010 to 2020. Clinical characteristics collected included demographics, cancer history, reconstructive techniques [autologous-based reconstruction (ABR) vs. implant-based reconstruction (IBR)] and surgical and oncologic outcomes such as complications, recurrence, and mortality. Factors impacting whether patients underwent ABR versus IBR were assessed, as well as differences in outcomes between the two procedures. Statistical significance was defined as P<0.05. Results: During the 10-year period, 52.9% (n=127) of all post-mastectomy TNBC patients (n=240) underwent breast reconstruction, most frequently immediately after mastectomy (97.0%). Most patients underwent IBR compared to ABR (82.4% vs. 14.5%). Patients undergoing ABR were older than IBR patients (54.3 vs. 46.4 years; P=0.040) and had a higher body mass index (BMI; 30.0 vs. 26.1 kg/m2; P=0.007). Patients more often pursued ABR if they had a prior breast cancer history (36.8% vs. 16.7%; P=0.041) or experienced TNBC recurrence (26.3% vs. 9.3%; P=0.034), while primary TNBC patients more often opted for IBR. Reconstructive type did not impact complications (ABR 31.6% vs. IBR 16.8%, P=0.131), recurrence (ABR 15.8% vs. IBR 13.0%, P=0.719), or mortality (ABR 0.0% vs. IBR 6.5%, P=0.593) rates. Conclusions: Factors such as age, BMI, and breast cancer history impacted choice of reconstructive technique among TNBC women. No differences in complications, recurrence, or mortality occur in these high-risk patients regardless of reconstructive technique, highlighting that neither ABR nor IBR is superior in regard to surgical and oncologic safety in post-mastectomy TNBC patients.

Prophylactic Lymphovenous Bypass at the Time of Axillary Lymph Node Dissection Decreases Rates of Lymphedema.

Background: Breast cancer-related lymphedema impacts 30% to 47% of women who undergo axillary lymph node dissection (ALND). Studies evaluating the effectiveness of prophylactic lymphovenous bypass (LVB) at the time of ALND have had small patient populations and/or short follow-up. The aim of this study is to quantitatively and qualitatively evaluate prophylactic LVB in patients with breast cancer. Methods: A retrospective review of patients who underwent ALND from 2018 to 2022 was performed. Patients were divided into cohorts based on whether they underwent prophylactic LVB at the time of ALND. Primary outcomes included 30-day complications and lymphedema. Lymphedema was quantitatively evaluated by bioimpedance analysis, with L-dex scores >7.1 indicating lymphedema. Results: One-hundred five patients were identified. Sixty-four patients (61.0%) underwent ALND and 41 patients (39.0%) underwent ALND+LVB. Postoperative complications were similar between the cohorts. At a median follow-up of 13.3 months, lymphedema occurred significantly higher in the ALND only group compared with ALND+LVB group (50.0% vs 12.2%; P < 0.001). ALND without LVB was an independent risk factor for lymphedema development (odds ratio, 4.82; P = 0.003). Conclusions: Prophylactic LVB decreases lymphedema and is not associated with increased postoperative complications. A multidisciplinary team approach is imperative to decrease lymphedema development in this patient population.

Retrospective review of complications and outcomes in COVID-19-positive patients with comorbidities undergoing limb salvage procedures in a tertiary care wound center.

INTRODUCTION: COVID-19 illness is associated with increased operative risks, ranging from delayed wound healing and coagulopathy to increased risk of mortality. OBJECTIVE: This article describes the authors' recent experience of the implications of COVID-19 on limb salvage procedures. MATERIALS AND METHODS: Patients who underwent LE limb salvage procedures within 30 days of a positive COVID-19 diagnosis were retrospectively reviewed. Patient demographics, comorbidities, surgical factors, postoperative complications, and management were collected. RESULTS: Of 597 patients screened from February 2020 to March 2022, a total of 67 (11.2%) were diagnosed with COVID-19, of which 17 received the diagnosis within 30 days of surgery and were thus included. Average follow-up was 43 ± 3.2 months, at which point 6 (35.3%) were fully healed. The mortality rate at the most recent follow-up visit was 29.4% of patients (n = 5). Two patients required admission to the SICU following index procedure, and 1 necessitated a return to the operating room. CONCLUSION: COVID-19 may negatively affect the wound healing process while increasing the mortality rate amongst patients with multiple or severe comorbidities undergoing limb salvage procedures. Medical providers need to be aware of the complexity of these patients and apply a multi-disciplinary protocol to obtain successful outcomes.
