BACKGROUND:  Older and frailer patients are increasingly undergoing free or pedicled tissue transfer for lower extremity (LE) limb salvage. This novel study examines the impact of frailty on postoperative outcomes in LE limb salvage patients undergoing free or pedicled tissue transfer.

METHODS:  The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database (2010-2020) was queried for free and pedicled tissue transfer to the LE based on Current Procedural Terminology and the International Classification of Diseases9/10 codes. Demographic and clinical variables were extracted. The five-factor modified frailty index (mFI-5) was calculated using functional status, diabetes, chronic obstructive pulmonary disease, congestive heart failure, and hypertension. Patients were stratified by mFI-5 score: no frailty (0), intermediate frailty (1), and high frailty (2 + ). Univariate analysis and multivariate logistic regression were performed.

RESULTS:  In total, 5,196 patients underwent free or pedicled tissue transfer for LE limb salvage. A majority were intermediate (n = 1,977) or high (n = 1,466) frailty. High frailty patients had greater rates of comorbidities-including those not in the mFI-5 score. Higher frailty was associated with more systemic and all-cause complications. On multivariate analysis, the mFI-5 score remained the best predictor of all-cause complications-with high frailty associated with 1.74 increased adjusted odds when compared with no frailty (95% confidence interval: 1.47-2.05).

CONCLUSION:  While flap type, age, and diagnosis were independent predictors of outcomes in LE flap reconstruction, frailty (mFI-5) was the strongest predictor on adjusted analysis. This study validates the mFI-5 score for preoperative risk assessment for flap procedures in LE limb salvage. These results highlight the likely importance of prehabilitation and medical optimization prior to limb salvage.

BACKGROUND:  Use of pedicled flaps in vascular procedures is associated with decreased infection and wound breakdown. We evaluated the risk profile and postoperative complications associated with lower extremity open vascular procedures with and without pedicled flaps.

METHODS:  The American College of Surgeons National Surgical Quality Improvement Program database (2010-2020) was queried for Current Procedural Terminology codes representing lower extremity open vascular procedures, including trunk and lower extremity pedicled flaps. Flap patients were compared with a randomized control group without flaps (1:3 cases to controls). Univariate and multivariate analyses were performed.

RESULTS:  We identified 132,934 adults who underwent lower extremity open vascular procedures. Concurrent pedicled flaps were rare (0.7%), and patients undergoing bypass procedures were more likely to receive a flap than nonbypass patients (69 vs. 64%, p < 0.0001). Flap patients had greater comorbidities. On univariate analysis, flap patients were more likely to experience wound (p = 0.0026), mild systemic (p < 0.0001), severe systemic (p = 0.0452), and all-cause complications (p < 0.0001). After adjusting for factors clinically suspected to be associated with increased risk (gender, body mass index, procedure type, American Society of Anesthesiologists classification, functional status, diabetes, smoking, and albumin < 3.5 mg/dL), wound (p = 0.096) and severe systemic complications (p = 0.0719) were no longer significantly associated with flap patients.

CONCLUSION:  Lower extremity vascular procedures are associated with a high risk of complications. Use of pedicled flaps remains uncommon and more often performed in patients with greater comorbid disease. However, after risk adjustment, use of a pedicled flap in high-risk patients may be associated with lower than expected wound and severe systemic complications.

INTRODUCTION: Metabolic syndrome (MetS) is characterized by cardiometabolic abnormalities such as hypertension, obesity, diabetes, or dyslipidemia. This study aims to evaluate the association of MetS on the postoperative outcomes of ventral, umbilical, and epigastric hernia repair using component separation.

METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was used to identify patients who underwent ventral, umbilical, and epigastric hernia repair with component separation between 2015 and 2021. MetS status was defined as patients receiving medical treatment for diabetes mellitus and hypertension, with a body mass index greater than 30 kg/m2. Propensity matching was performed to generate two balanced cohorts with and without MetS. T-tests and Fisher's Exact tests assessed group differences. Logistic regression models evaluated complications between the groups.

RESULTS: After propensity score matching, 3930 patients were included in the analysis, with 1965 in each group (MetS versus non-MetS). Significant differences were observed in the severity and clinical presentation of hernias between the groups. The MetS cohort had higher rates of incarcerated hernia (39.1% versus 33.2%; P < 0.001), and recurrent ventral hernia (42.7% versus 36.5%; P < 0.001) compared to the non-MetS cohort. The MetS group demonstrated significantly increased rates of renal insufficiency (P = 0.026), unplanned intubation (P = 0.003), cardiac arrest (P = 0.005), and reoperation rates (P = 0.002) than the non-MetS cohort. Logistic regression models demonstrated higher likelihood of postoperative complications in the MetS group, including mild systemic complications (OR 1.25; 95%CI 1.030-1.518; P = 0.024), severe systemic complications (OR 1.63; 95%CI 1.248-2.120; P < 0.001), and reoperation (OR 1.47; 95%CI 1.158-1.866; P = 0.002). There were no significant differences in the rates of 30-d wound complications between groups.

CONCLUSIONS: The presence of metabolic derangement appears to be associated with adverse postoperative medical outcomes and increased reoperation rates after hernia repair with component separation. These findings highlight the importance of optimizing preoperative comorbidities as surgeons counsel patients with MetS.

Foppiani JA, Kim E, Weidman AA, et al. Continuing Insurance Coverage for Flap-Based Breast Reconstruction: Is There a Reservation Cost Related to a Woman’s Abdominal Flap Choice?. Annals of plastic surgery. 2024;92(4S Suppl 2):S228-S233. doi:10.1097/SAP.0000000000003804

BACKGROUND: The recent proposed alterations to the Centers for Medicare and Medicaid Services regulations, although subsequently reversed on August 21, 2023, have engendered persistent concerns regarding the impact of insurance policies on breast reconstruction procedures coverage. This study aimed to identify factors that would influence women's preferences regarding autologous breast reconstruction to better understand the possible consequences of these coverage changes.

METHODS: A survey of adult women in the United States was conducted via Amazon Mechanical Turk to assess patient preferences for breast reconstruction options, specifically deep inferior epigastric perforator (DIEP) and transverse rectus abdominis myocutaneous (TRAM) flap surgery. The Cochrane-Armitage test evaluated trends in flap preferences concerning incremental out-of-pocket payment increases.

RESULTS: Of 500 total responses, 485 were completed and correctly answered a verification question to ensure adequate attention to the survey, with respondents having a median (interquartile range) age of 26 (25-39) years. When presented with the advantages and disadvantages of DIEP versus TRAM flaps, 78% of respondents preferred DIEP; however, as DIEP's out-of-pocket price incrementally rose, more respondents favored the cheaper TRAM option, with $3804 being the "indifference point" where preferences for both procedures converged (P < 0.001). Notably, respondents with a personal history of breast reconstruction showed a higher preference for DIEP, even at a $10,000 out-of-pocket cost (P = 0.04).

CONCLUSIONS: Out-of-pocket cost can significantly influence women's choices for breast reconstruction. These findings encourage a reevaluation of emergent insurance practices that could potentially increase out-of-pocket costs associated with DIEP flaps, to prevent cost from decreasing equitable patient access to most current reconstructive options.

Foppiani JA, Alvarez AH, Kim EJ, et al. The value of microvascular breast reconstruction: Cost equivalence of TRAM and DIEP flaps implications in the era of CMS reforms.. Microsurgery. 2024;44(4):e31185. doi:10.1002/micr.31185

BACKGROUND: Recent CMS billing changes have raised concerns about insurance coverage for deep inferior epigastric perforator (DIEP) flap breast reconstruction. This study compared the costs and utilization of transverse rectus abdominis myocutaneous (TRAM), DIEP, and latissimus dorsi (LD) flaps in breast reconstruction.

METHOD: The study utilized the National Inpatient Sample database to identify female patients who underwent DIEP, TRAM, and LD flap procedures from 2016 to 2019. Key data such as patient demographics, length of stay, complications, and costs (adjusted to 2021 USD) were analyzed, focusing on differences across the flap types.

RESULTS: A total of 17,770 weighted patient encounters were identified, with the median age being 51. The majority underwent DIEP flaps (73.5%), followed by TRAM (14.2%) and LD (12.1%) flaps. The findings revealed that DIEP and TRAM flaps had a similar length of stay (LOS), while LD flaps typically had a shorter LOS. The total hospital charges to costs using cost-to-charge ratio were also comparable between DIEP and TRAM flaps, whereas LD flaps were significantly less expensive. Factors such as income quartile, primary payer of hospitalization, and geographic region significantly influenced flap choice.

CONCLUSION: The study's results appear to contradict the prevailing notion that TRAM flaps are more cost-effective than DIEP flaps. The total hospital charges to costs using cost-to-charge ratio and hospital stays associated with TRAM and DIEP flaps were found to be similar. These findings suggest that changes in the insurance landscape, which may limit the use of DIEP flaps, could undermine patient autonomy while not necessarily reducing healthcare costs. Such policy shifts could favor less costly options like the LD flap, potentially altering the landscape of microvascular breast reconstruction.

Bloom JA, Wareham C, Chahine E, et al. A Cost-Utility Analysis of the Use of -125 mm Hg Closed-incision Negative Pressure Therapy in Oncoplastic Breast Surgery.. Plastic and reconstructive surgery. Global open. 2024;12(10):e6163. doi:10.1097/GOX.0000000000006163

BACKGROUND: Closed-incision negative pressure therapy (ciNPT) decreases the rate of wound complications in oncoplastic breast surgery (OBS) but at a fiscal cost. Our aim was to examine the cost-utility of ciNPT in OBS.

METHODS: A literature review was performed to obtain the probabilities and outcomes for the treatment of unilateral breast cancer with OBS with ciNPT versus without. Reported utility scores in the literature were used to calculate quality-adjusted life years (QALYs) for each health state. A decision analysis tree was constructed with rollback analysis to determine the more cost-effective strategy. An incremental cost-utility ratio was calculated. Sensitivity analyses were performed.

RESULTS: OBS with ciNPT is associated with a higher clinical effectiveness (QALY) of 33.43 compared to without (33.42), and relative cost increase of $667.89. The resulting incremental cost-utility ratio of $57432.93/QALY favored ciNPT. In one-way sensitivity analysis, ciNPT was the more cost-effective strategy if the cost of ciNPT was less than $1347.02 or if the probability of wound dehiscence without was greater than 8.2%. Monte Carlo analysis showed a confidence of 75.39% that surgery with ciNPT is more cost effective.

CONCLUSION: Despite the added cost, surgery with ciNPT is cost-effective. This finding is a direct result of decreased overall wound complications with ciNPT.

Escobar-Domingo MJ, Mahmoud AA, Lee D, et al. Representation of Racial Diversity on US Plastic Surgery Websites: A Cross-sectional Study: Racial Diversity on Plastic Surgery Websites.. Annals of plastic surgery. 2024;93(6):653-657. doi:10.1097/SAP.0000000000004051

BACKGROUND: The racial diversity portrayed in plastic and reconstructive surgery (PRS) media is an important indicator of an inclusive environment for potential patients. To evaluate the degree to which PRS websites demonstrate inclusivity, we assessed the racial composition of both patients and plastic surgeons depicted on the most visited academic and private PRS websites to determine the extent to which racial diversity is represented.

METHODS: A cross-sectional study was conducted in September 2023. The 10 most visited websites in each state were identified. Sociodemographic characteristics including race and sex of patients and plastic surgeons, as well as the type of practice, were collected. Race was classified according to individuals' Fitzpatrick Phototypes into White and non-White. Differences in patient and surgeon representation were compared to the 2020 US Census and the 2020 ASPS demographics using χ 2 tests. Subgroup analyses were conducted to identify differences by type of practice and region.

RESULTS: We analyzed a total of 2,752 patients from 462 websites belonging to 930 plastic surgeons. PRS websites were predominantly from private practices (93%). Regarding patient representation, 92.6% were female, 7.4% were male, 87.6% were White, and 12.4% were non-White. The surgeon population on the studied webpages was 75.1% male, 92.1% White, and 7.8% non-White. Statistically significant differences were found in the patient population when compared to the 2020 national ( P < 0.001) and regional ( P < 0.001) US Census demographics and the 2020 ASPS Statistics Report ( P < 0.001). Although minority representation was significantly higher on academic websites compared to private practice (22.9% vs. 12.1%; P = 0.007), both were significantly lower than the percentage of minority patients undergoing PRS.

CONCLUSIONS: This study illuminates racial disparities in the representation of racial groups among patients and plastic surgeons in the most frequented plastic surgery websites. Moreover, it underscores the imperative to bolster racial diversity within the digital content of both private and academic PRS websites. Greater racial representation can foster a more inclusive perception of the plastic surgery field, which may potentially broaden access to care and enrich the professional landscape.

Veeramani A, Johnson AR, Lee BT, Dowlatshahi AS. Readability, Understandability, Usability, and Cultural Sensitivity of Online Patient Educational Materials (PEMs) for Lower Extremity Reconstruction: A Cross-Sectional Study.. Plastic surgery (Oakville, Ont.). 2024;32(3):452-459. doi:10.1177/22925503221120548

Background: Lower extremity reconstructive surgery is an evolving field wherein patients rely on accessible online materials to engage with their perioperative care. This study furthers existing research in this area by evaluating the readability, understandability, actionability, and cultural sensitivity of online health materials for lower extremity reconstruction. Methods: We identified the 10 first-appearing, educational sites found by searching the phrases "leg saving surgery", "limb salvage surgery," and "leg reconstruction surgery". Readability analysis was conducted with validated tools, including Simple Measure of Gobbledygook (SMOG). Understandability and actionability were assessed with Patient Education and Materials Assessment Tool (PEMAT), while cultural sensitivity was measured with Cultural Sensitivity Assessment Tool (CSAT). A Cohen's κ value was calculated (PEMAT and CSAT analyses) for inter-rater agreement. Results: The mean SMOG reading level for websites was 13.12 (college-freshman reading level). The mean PEMAT understandability score was 61.8% and actionability score was 26.0% (κ = 0.8022), both below the 70% acceptability threshold. The mean CSAT score was 2.6 (κ = 0.73), exceeding the 2.5 threshold for cultural appropriateness. Conclusion: Online PEM for lower extremity reconstruction continue to fall below standards of readability, understandability, and actionability; however, they meet standards of cultural appropriateness. As patients rely on these materials, creators can use validated tools and positive examples from existing PEM for greater patient accessibility.

Foppiani JA, Raska O, Galinaud C, et al. Comparing Collagenase and Tissue Subcision for Cellulite Treatment of the Buttock and Thigh Regions: A Systematic Review and Meta-analysis.. Plastic and reconstructive surgery. Global open. 2024;12(6):e5857. doi:10.1097/GOX.0000000000005857

BACKGROUND: In this systematic review, we assessed the therapeutic efficacy and safety of Clostridium histolyticum collagenase (CCH) and tissue subcision (TS) for treating cellulite, which ranges from subtle to pronounced lesions.

METHODS: A systematic review was performed following PRISMA guidelines for CCH and TS treatment to the thigh and gluteal regions. A proportion meta-analysis was then conducted using Stata statistical software.

RESULTS: A total of 14 studies were incorporated into the final analysis. Nine focused on TS and five on CCH injection, collectively reporting outcomes for 1254 patients. Of these, 465 received CCH injection and 789 underwent subcision. For bruising, rates were 89% [95% confidence interval (CI), 71%-96%] with CCH injection and 99% (95% CI, 85%-99%) for subcision; pain requiring analgesic was reported at 74% (95% CI, 55%-87%) for CCH and 60% (95% CI, 43%-76%) for subcision; both showed induration at 7% (95% CI, 5%-11% for CCH, 95% CI, 2%-25% for subcision), whereas skin discoloration was higher post-CCH injection at 16% (95% CI, 10%-26%) compared with 7% (95% CI, 5%-10%) postsubcision.

CONCLUSIONS: Both CCH and TS seem effective treatments for cellulite. However, upon evaluating the adverse outcomes between the two modalities, subcision demonstrated a higher incidence of bruising, albeit similar rates of induration compared with CCH injection. Conversely, the CCH injection group manifested a higher propensity for pain requiring analgesia and notably exhibited increased instances of skin discoloration compared with their subcision patient group. Further standardized research is crucial for more informed cellulite treatment decisions and for comparing efficacy, safety, and cost-effectiveness between TS and CCH.

Escobar-Domingo MJ, Bustos VP, Mahmoud AA, et al. The Impact of Race and Ethnicity in Microvascular Head and Neck Reconstruction Postoperative Outcomes: A Nationwide Data Analysis.. The Journal of craniofacial surgery. 2024;35(7):1952-1957. doi:10.1097/SCS.0000000000010593

BACKGROUND: Racial and ethnic disparities have been extensively reported across surgical specialties, highlighting existing healthcare inequities. Nevertheless, evidence is lacking regarding their influence on postoperative outcomes after head and neck reconstruction. This study aimed to evaluate the impact of race and ethnicity on postoperative complications in head and neck microvascular reconstruction.

METHODS: The ACS-NSQIP database was used to identify patients who underwent head and neck microvascular reconstruction between 2012 and 2022. Baseline characteristics were compared based on race (White, non-White) and ethnicity (Hispanic, non-Hispanic). Group differences were assessed using t tests and Fisher Exact tests. Multivariable logistic regression models were constructed to evaluate postoperative complications between the groups. A Cochran-Armitage test was conducted to evaluate the significance of trends over time.

RESULTS: A total of 11,373 patients met inclusion criteria. Among them, 9,082 participants reported race, and 9,428 reported ethnicity. Multivariable analysis demonstrated that Hispanic patients were more likely to experience 30-day readmission (OR 6.7; 95% CI, 1.17-38.4; P=0.032) and had an average total length of stay of 5.25 days longer (95% CI, 0.84-9.65; P=0.020) compared with non-Hispanic patients. Additional subgroup analyses revealed higher rates of all readmissions among non-White patients, particularly those indicated by malignancy (OR 1.23; 95% CI, 1.1-1.4; P=0.002). No significant differences were found in mortality, reoperation rates, and operative times between racial and ethnic groups.

CONCLUSIONS: The findings of this study suggest that ethnicity may be a significant risk factor for readmission in head and neck microvascular reconstruction. However, future studies are needed to further clarify the impact of race and ethnicity on longer postoperative outcomes, particularly in head and neck cancer minorities.
