Readability, Understandability, Usability, and Cultural Sensitivity of Online Patient Educational Materials (PEMs) for Lower Extremity Reconstruction: A Cross-Sectional Study.

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.

Contexte : La chirurgie reconstructrice du membre inférieur est un domaine en pleine évolution où les patients s'appuient sur des documents en ligne afin de se lancer dans leurs soins périopératoires. Cette étude est la prolongation d'une recherche existante dans ce domaine pour évaluer la lisibilité, l'intelligibilité, la mise en pratique et la sensibilité culturelle des documents de santé disponibles en ligne pour la reconstruction du membre inférieur. Méthodes : Nous avons identifié 10 sites éducatifs d'apparition récente en faisant une recherche avec les mots « chirurgie de sauvetage de la jambe ¼, « chirurgie de sauvetage d'un membre ¼ et « chirurgie reconstructrice de la jambe ¼. Une analyse de lisibilité a été effectuée avec des outils validés dont Simple Measure of Gobbledygook (SMOG). L'intelligibilité et la mise en pratique ont été évaluées avec PEMAT, tandis que la sensibilité culturelle était mesurée avec le CSAT (outil d'évaluation et de sensibilité culturelle). La valeur k de Cohen a été calculée pour les analyses avec le PEMAT et le CSAT, pour la concordance interévaluateurs. Résultats : Le niveau de lisibilité moyen avec le SMOG pour les sites Web était de 13.12 (niveau de lecture d'entrée au collège). Le score moyen d'intelligibilité (PEMAT) était de 61.8% et le score de mise en pratique était de 26.0% (kappa = 0,8022), tous les deux en dessous du score d'acceptabilité de 70%. Le score CSAT moyen était de 2.6 (kappa = 0,73), dépassant le seuil de 2.5. Conclusion : Les documents éducatifs pour patients sur la reconstruction du membre inférieur restent en dessous des normes de lisibilité, d'intelligibilité et de mise en action. En revanche, ils satisfont les normes de respect de la culture. Considérant que les patients s'appuient sur ces documents, leurs créateurs peuvent utiliser des outils validés et des exemples positifs issus de documents existants pour une plus grande accessibilité par les patients.

Enhancing Post-Mastectomy Care: Telehealth's Impact on Breast Reconstruction Accessibility for Breast Cancer Patients.

OBJECTIVE: To examine how the recent sharp rise in telemedicine has impacted trends in accessibility of breast reconstruction (BR). PATIENTS AND METHODS: A retrospective study reviewed patients who underwent a total mastectomy at our institution from 1 August 2016 to 31 January 2022. By comparing cohorts before and during the widespread implementation of telemedicine, we assessed telehealth's impact on healthcare accessibility, measured by distance from patients' residences to our institution. RESULTS: A total of 359 patients were included in this study. Of those, 176 received total mastectomy prior to the availability of telemedicine, and 183 in the subsequent period. There were similar baseline characteristics among patients undergoing mastectomy, including distance from place of residence to hospital (p = 0.67). The same proportion elected to receive BR between groups (p = 0.22). Those declining BR traveled similar distances as those electing the procedure, both before the era of widespread telemedicine adoption (40.3 and 35.6 miles, p = 0.56) and during the height of telemedicine use (22.3 and 61.3 miles, p = 0.26). When tracking follow-up care, significantly more patients during the pandemic pursued at least one follow-up visit with their original surgical team, indicative of the increased utilization of telehealth services. CONCLUSIONS: While the rate of BR remained unchanged during the pandemic, our findings reveal significant shifts in healthcare utilization, highly attributed to the surge in telehealth adoption. This suggests a transformative impact on breast cancer care, emphasizing the need for continued exploration of telemedicine's role in enhancing accessibility and patient follow-up in the post-pandemic era.

BREAST-Q Analysis of Reduction Mammaplasty: Do Postoperative Complications of Breast Reduction Surgery Negatively Affect Patient Satisfaction?

BACKGROUND: Reduction mammaplasty can provide symptomatic relief to patients suffering from macromastia, however complications such as dehiscence are common. It is unknown if the presence of complications may affect patient reported outcomes. OBJECTIVES: This study aims to (1) determine risk factors for development of complications, and (2) to examine the correlation between postoperative complications and patient reported outcomes in reduction mammaplasty. METHODS: A single-center retrospective chart review was performed on patients who received reduction mammaplasties (CPT19318) between 1/17-2/23 by thirteen surgeons. Breast cancer cases and oncoplastic reconstructions were excluded. Patients with >1 complication were grouped into the complications cohort. BREAST-Q-survey was used to assess satisfaction. RESULTS: A total of 661 patients were included for analysis, and 131 patients developed at least one complication. Patients in the complication group had significantly higher average ages and body mass indexes, and a higher likelihood of hypertension and diabetes (p<0.01). Among 180 BREAST-Q responders, 41 had at least one complication. There were no significant differences between the two groups across survey outcomes. Although obese patients were more likely to develop infection and require revisions (p<0.01), no significant differences in subgroup analysis of patient-reported outcomes focusing on obese patients were observed. CONCLUSIONS: Obesity, hypertension, and diabetes were associated with postoperative complications of reduction mammaplasty. Patients with complications had similar postoperative Breast-Q satisfaction to patients without complications. While risk optimization is critical, patients and surgeons should be reassured that satisfaction may be achieved even in the event of a complication.

Interstitial cell of Cajal-like cells (ICC-LC) exhibit dynamic spontaneous activity but are not functionally innervated in mouse urethra.

Urethral smooth muscle cells (USMC) contract to occlude the internal urethral sphincter during bladder filling. Interstitial cells also exist in urethral smooth muscles and are hypothesized to influence USMC behaviours and neural responses. These cells are similar to Kit+ interstitial cells of Cajal (ICC), which are gastrointestinal pacemakers and neuroeffectors. Isolated urethral ICC-like cells (ICC-LC) exhibit spontaneous intracellular Ca2+ signalling behaviours that suggest these cells may serve as pacemakers or neuromodulators similar to ICC in the gut, although observation and direct stimulation of ICC-LC within intact urethral tissues is lacking. We used mice with cell-specific expression of the Ca2+ indicator, GCaMP6f, driven off the endogenous promoter for Kit (Kit-GCaMP6f mice) to identify ICC-LC in situ within urethra muscles and to characterize spontaneous and nerve-evoked Ca2+ signalling. ICC-LC generated Ca2+ waves spontaneously that propagated on average 40.1 ± 0.7 µm, with varying amplitudes, durations, and spatial spread. These events originated from multiple firing sites in cells and the activity between sites was not coordinated. ICC-LC in urethra formed clusters but not interconnected networks. No evidence for entrainment of Ca2+ signalling between ICC-LC was obtained. Ca2+ events in ICC-LC were unaffected by nifedipine but were abolished by cyclopiazonic acid and decreased by an antagonist of Orai Ca2+ channels (GSK-7975A). Phenylephrine increased Ca2+ event frequency but a nitric oxide donor (DEA-NONOate) had no effect. Electrical field stimulation (EFS, 10 Hz) of intrinsic nerves, which evoked contractions of urethral rings and increased Ca2+ event firing in USMC, failed to evoke responses in ICC-LC. Our data suggest that urethral ICC-LC are spontaneously active but are not regulated by autonomic neurons.

The action of coenzyme B12-dependent diol dehydratase on 3,3,3-trifluoro-1,2-propanediol results in elimination of all the fluorides with formation of acetaldehyde.

3,3,3-Trifluoro-1,2-propanediol undergoes complete defluorination in two distinct steps: first, the conversion into 3,3,3-trifluoropropionaldehyde catalyzed by adenosylcobalamin (coenzyme B12)-dependent diol dehydratase; second, non-enzymatic elimination of all three fluorides from this aldehyde to afford malonic semialdehyde (3-oxopropanoic acid), which is decarboxylated to acetaldehyde. Diol dehydratase accepts 3,3,3-trifluoro-1,2-propanediol as a relatively poor substrate, albeit without significant mechanism-based inactivation of the enzyme during catalysis. Optical and EPR spectra revealed the steady-state formation of cob(II)alamin and a substrate-derived intermediate organic radical (3,3,3-trifluoro-1,2-dihydroxyprop-1-yl). The coenzyme undergoes Co-C bond homolysis initiating a sequence of reaction by the generally accepted pathway via intermediate radicals. However, the greater steric size of trifluoromethyl and especially its negative impact on the stability of an adjacent radical center compared to a methyl group has implications for the mechanism of the diol dehydratase reaction. Nevertheless, 3,3,3-trifluoropropionaldehyde is formed by the normal diol dehydratase pathway, but then undergoes non-enzymatic conversion into acetaldehyde, probably via 3,3-difluoropropenal and malonic semialdehyde.

The Impact of Metabolic Syndrome on Postoperative Outcomes in Abdominal Body Contouring: A Propensity Score-Matched Nationwide Analysis.

BACKGROUND: Metabolic syndrome (MetS) represents cardiometabolic dysregulation, defined by hypertension, obesity, diabetes, and dyslipidemia. There remains a significant gap in our understanding of whether MetS impacts outcomes of abdominal body contouring procedures. We aimed to assess the influence of MetS on postoperative outcomes of abdominal body contouring by concurrent abdominoplasty and panniculectomy. METHODS: The ACS-NSQIP database was utilized to identify patients who underwent concurrent abdominoplasty and panniculectomy procedures from 2012 to 2022. Through propensity score matching, distinct cohorts were established based on the presence of MetS, characterized by patients receiving medical interventions for diabetes mellitus and hypertension, with a body mass index exceeding 30 kg/m2. Univariate and multivariate analyses were conducted to evaluate differences between groups. RESULTS: A total of 14,642 patients underwent abdominal body contouring from 2012 to 2022. Following propensity score matching, 730 patients were included in the analysis, with 365 in each group (MetS vs. non-MetS). Bivariate analysis revealed a longer hospital length of stay (2.3 vs. 1.6 days; p = 0.007) in the MetS cohort compared to the non-MetS cohort. Patients diagnosed with MetS had an average length of stay of 0.6 days longer than non-MetS patients (95% CI [0.17, 1.01]; p = 0.007). No noteworthy disparities were observed in the rates of 30-day wound complications, mild systemic, and severe systemic complications, and readmission rates between the groups. CONCLUSIONS: Our findings suggest that abdominal body contouring remains a secure option for patients with MetS. Nonetheless, the longer hospital length stays observed in patients with MetS may translate to increased overall costs to the healthcare system. Continued research is warranted to comprehensively assess the economic implications of MetS in the context of abdominal body contouring.

Beyond the language barrier: Assessing health literacy of Spanish breast cancer surgery resources.

BACKGROUND: Breast cancer is the leading cause of cancer-specific mortality in Hispanic women in the United States. Given the complexity of treatment options, disparities in access to quality care, and increased rates of inadequate or marginal health literacy within this population, these patients face significant barriers to informed decision-making. We aimed to assess the health literacy of Spanish breast cancer surgery websites. METHODS: A web search using "cirugía de cancer de mama or seno" was performed to identify the top 20 websites in Spanish, divided on the basis of affiliation with academic centers or private institutions and by international/US region. Validated metrics were used to assess readability, understandability, actionability, and cultural sensitivity using Simplified Measure of Gobbledygook in Spanish, Patient Education and Materials Assessment for Understandability and Actionability, and Cultural Sensitivity and Assessment Tool, respectively. RESULTS: Online materials in Spanish had a mean reading grade level of 10.9 (Simplified Measure of Gobbledygook in Spanish) for academic centers and 10.4 for private institutions. The average understandability score was significantly greater for academic centers at 77% compared with private institutions at 67% (P = .019). Actionability scores were low for both centers at 26% and 37%, respectively. The mean Cultural Sensitivity and Assessment Tool scores were 2.3 and 2.2, respectively. CONCLUSION: Current Spanish resources for breast cancer surgery are unfitting not only from a readability standpoint but also in their quality and cultural sensitivity. As the Latino population in the United States increases and online resources become more accessible, we must ensure that these resources cater to their target audience, bridging the health care access gap and empowering patients in decision-making.

Gender Diversity Among Reconstructive Microsurgery Studies Based on the Relative Citation Ratio: An 18-Year Analysis.

BACKGROUND: Gender disparities in plastic surgery authorship have been previously described in the literature. The relative citation ratio (RCR) index is a new metric that normalizes citation rates for field and time, which can be utilized to compare authors. This study aims to evaluate differences in gender authorship in reconstructive microsurgery (RM) papers, as well as the impact of gender on the RCR index. METHODS: A PubMed query isolated RM studies between 2002 and 2020 across the 3 highest impact PS journals. Author names and RCR information were collected from NIH iCite. The likely gender was adjudicated by using NamSor-Software. Unpaired Wilcoxon rank-sum and chi-square tests were used to assess differences between groups. RESULTS: Of 1146 articles (2172 authors), there was a significant difference between the proportion of females as senior authors compared to first authors (P < 0.001). Overall, females represented 15.4% of all authors, 19.7% of first authors, and 11.3% of senior authors. Males had a significantly higher weighted RCR (P < 0.0001) and number of publications (P < 0.0001), which remained significant when stratified by first and senior author. Female authors collectively had a higher mean RCR (P = 0.008) and among first authors (P < 0.0001), with no significant difference among senior authors (P = 0.47). CONCLUSION: A considerably greater number of males are publishing in reconstructive microsurgery compared to females, with significantly more males being senior authors compared to first authors. Males had higher weighted RCR scores and publications compared to females. This study suggests that equity in gender authorship within the field is yet to be achieved.

Representation of Racial Diversity on US Plastic Surgery Websites: A Cross-sectional Study: Racial Diversity on Plastic Surgery Websites.

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 χ2 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.

Navigating Aesthetic Pursuits: A Google Trends Insight into Cosmetic Tourism.

BACKGROUND: The popularity of cosmetic tourism may increase unnecessary risks for patients as postoperative care is variable. However, little is known about the current trends and public perception of this growing phenomenon. This study compares interest in cosmetic tourism in popular medical tourism destinations relative to the US. METHODS: Google Trends was queried from October 2017 to September 2023, examining trends over the full period and dissecting changes between 2017-2020 and 2020-2023. Search volume data were retrieved for the top international countries and the US for each of the top five cosmetic procedures, according to the ISAPS 2022 Global Survey. A p value < 0.05 was used for statistical significance. RESULTS: Searches for liposuction, blepharoplasty, breast augmentation, mastopexy, and abdominoplasty were compared between the US, Mexico, Turkey, Thailand, and Colombia. Google Trends data mirrored the prevalence of the two most common procedures, liposuction, and breast augmentation. Differences in interest regarding liposuction were greatest in Mexico, Thailand, and Turkey compared to the US (p < 0.05). Medical tourism for blepharoplasty had the highest search interest scores for Turkey and Thailand from 2017 to 2023 (p < 0.05). Significant differences were also consistent across all time intervals for breast augmentation, mastopexy, and abdominoplasty, with higher interest in Mexico and Turkey (p < 0.05). CONCLUSIONS: Google Trends analysis serves as an insightful tool for understanding cosmetic tourism. Changing trends bring the potential to assess worldwide versus country-specific procedure interest. These observed trends may foreshadow future international aesthetic procedure trends. NO LEVEL ASSIGNED: This journal requires that authors assign a level of evidence to each submission to which Evidence-Based Medicine rankings are applicable. This excludes Review Articles, Book Reviews, and manuscripts that concern Basic Science, Animal Studies, Cadaver Studies, and Experimental Studies.

Association of Metabolic Derangement and Postoperative Outcomes in Hernia Repair With Component Separation: A Propensity Score-matched Nationwide Analysis.

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.

Effect of pedicle type on breast reduction: Clinical and patient-reported outcomes.

PURPOSE: The choice of pedicle in reduction mammaplasty is highly variable with prior studies demonstrating high patient satisfaction in most cases. This study aimed to examine the impact of pedicle type on clinical and patient-reported outcomes in patients undergoing reduction mammaplasty. METHODS: A total of 588 patients underwent bilateral reduction mammaplasty with Wise pattern or modified Robertson incision by 13 surgeons at a single institution. Clinical outcomes were compared according to the pedicle type in all patients and BREAST-Q responders (32% response rate). Survey respondents were sub-grouped by resection volume, and the BREAST-Q satisfaction scores were compared. RESULTS: Among all included reduction mammoplasties, 439 (75%) were performed using inferior pedicles, and 149 (25%) using superior or superomedial pedicles. Responders and non-responders were similar in preoperative characteristics including age, body measurements, and comorbidities. Although a higher incidence of infection occurred among the responders, clinical outcomes were comparable across all pedicle types. A total of 187 patients completed the BREAST-Q. Compared to the superior pedicle group, respondents in the inferior pedicle group reported higher nipple satisfaction, even when adjusted for resection weight over 500 g. In contrast, the superior pedicle group had better sexual well-being scores, which persisted in resection weight less than 500 g (all p values <0.05). CONCLUSION: Inferior pedicles were associated with greater nipple satisfaction and superior pedicles were associated with greater sexual satisfaction. Our findings suggest that those with resections less than 500 g were more satisfied with superior pedicles whereas those with greater resections were more satisfied with inferior pedicles.

Comparing Collagenase and Tissue Subcision for Cellulite Treatment of the Buttock and Thigh Regions: A Systematic Review and Meta-analysis.

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.

The versatility of the scapular free flap: A workhorse flap? A systematic review and meta-analysis.

BACKGROUND: The scapular free flap (SFF) is essential in complex reconstructive surgery and often indicated in complex defects with compromised or poor local tissue integrity. This review aims to assess the versatility and reliability of the SFF during reconstruction. METHODS: A comprehensive literature review of multiple databases was conducted following the PRISMA guidelines. An analysis of pooled data was performed to evaluate flap failure rate for any anatomical unit using SFF as the primary endpoints. Secondary endpoints included other complication rates after reconstruction such as partial flap loss, revision surgery, fistula, hematoma, and infection. RESULTS: A total of 110 articles were included, with 1447 pooled flaps. The main recipient site was the head and neck region (89.0%). Major indications for reconstruction were malignancy (55.3%), burns (19.2%), and trauma (9.3%). The most common types of flaps were osteocutaneous (23.3%), cutaneous (22.6%), and chimeric (18.0%). The pooled flap failure rate was 2% (95%CI: 1%-4%). No significant heterogeneity was present across studies (Q statistic 20.2, p = .69; I2 .00%, p = .685). Nonscapular supplementary flaps and grafts were required in 61 cases. The average length and surface area of bone flaps were 7.2 cm and 24.8cm2, respectively. The average skin paddle area was 134.2cm2. CONCLUSION: The SFF is a useful adjunct in the reconstructive surgeon's armamentarium as evidence by its intrinsic versatility and diverse clinical indications. Our data suggest a low failure rate in multicomponent defect reconstruction, especially in head and neck surgery. SFFs enable incorporation of multiple tissue types and customizable dimensions-both for vascularized bone and cutaneous skin-augmenting its value in the microsurgeon's repertoire as a chimeric flap. Further research is necessary to overcome the conventional barriers to SFF utilization and to better comprehend the specific scenarios in which the SFF can serve as the preferred alternative workhorse flap.

An Institutional Analysis of Early Postoperative Free Tissue Transfer Takeback Procedures.

BACKGROUND: Postoperative free tissue transfer reexploration procedures are relatively infrequent but associated with increased overall failure rates. This study examines the differences between flaps requiring takeback versus no takeback, as well as trends in reexploration techniques that may increase the odds of successful salvage. METHODS: A retrospective review was conducted on all free tissue transfers performed at our institution from 2011 to 2022. Patients who underwent flap reexploration within 30 days of the original procedure were compared with a randomly selected control group who underwent free flap procedures without reexploration (1:2 cases to controls). Univariate and multivariate logistic regression analyses were performed. RESULTS: From 1,213 free tissue transfers performed in the study period, 187 patients were included in the analysis. Of the total flaps performed, 62 (0.05%) required takeback, and 125 were randomly selected as a control group. Free flap indication, flap type, reconstruction location, and number of venous anastomoses differed significantly between the two groups. Among the reexplored flaps, 8 (4.3% of the total) had a subsequent failure while 54 (87.10%) were salvaged, with significant differences in cause of initial flap failure, affected vessel type, and salvage technique. CONCLUSION: Free tissue transfers least prone to reexploration involved breast reconstruction in patients without predisposition to hypercoagulability or reconstruction history. When takeback operations were required, salvage was more likely in those without microvascular compromise or with an isolated venous injury who required a single exploratory operation.

Three-Dimensional Printing in Surgical Education: An Updated Systematic Review of the Literature.

INTRODUCTION: Three-dimensional printing (3DP) is being integrated into surgical practice at a significant pace, from preprocedural planning to procedure simulation. 3DP is especially useful in surgical education, where printed models are highly accurate and customizable. The aim of this study was to evaluate how 3DP is being integrated most recently into surgical residency training. METHODS: We performed a structured literature search of the OVID/MEDLINE, EMBASE, and PUBMED databases following the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Articles published from 2016 to 2023 that met predefined inclusion and exclusion criteria were included. Data extracted included surgical subspecialty using 3DP, application of 3DP, and any reported satisfaction measures of trainees. A thorough analysis of pooled data was performed to evaluate satisfaction rates among studies. RESULTS: A total of 85 studies were included. The median number of participants was 18 (interquartile range 10-27). Fourteen surgical disciplines were represented, with ear, nose, and throat/otolaryngology having the highest recorded utilization of 3DP models among residents and medical students (22.0%), followed by neurosurgery (14.0%) and urology (12.0%). 3DP models were created most frequently to model soft tissue (35.3%), bone (24.7%), vessel (14.1%), mixed (16.4%), or whole organs (6.66%) (Fig.1). Feedback from trainees was overwhelmingly positive regarding the fidelity of the models and their support for integration into their training programs. Among trainees, the combined satisfaction rate with their use in the curriculum was 95% (95% confidence interval, 0.92-0.97), and the satisfaction rate with the model fidelity was 90% (95% confidence interval, 0.86-0.94). CONCLUSIONS: There is wide variation in the surgical specialties utilizing 3DP models in training. These models are effective in increasing trainee comfort with both common and rare scenarios and are associated with a high degree of resident support and satisfaction. Plastic surgery programs may benefit from the integration of this technology, potentially strengthening future surgical curricula. Objective evaluations of their pedagogic effects on residents are areas of future research.

The value of microvascular breast reconstruction: Cost equivalence of TRAM and DIEP flaps implications in the era of CMS reforms.

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.

Development of "Explore Plastic Surgery": An Educational Program for Medical Students Without Home Residency Programs.

BACKGROUND: Medical students who attend institutions without plastic surgery residency programs are at a disadvantage in the plastic surgery match. We developed an educational program for medical students without home programs called Explore Plastic Surgery to provide an overview of the steps toward a career in plastic surgery. The purpose of this study was to assess the impact, utility, and success of the novel program. METHODS: Pre- and postevent surveys were distributed to participants. Survey data were analyzed including participant demographics, perceptions of barriers unique to those without home programs, and the overall event utility. RESULTS: Two hundred seventeen students registered for the program. Ninety-five participants completed the pre-event survey (44%), and of those, 57 participants completed the post-event survey (60%). There was an increase in understanding of the steps toward a career in plastic surgery ( P < 0.001), confidence in overcoming barriers ( P = 0.005), and level of comfort in reaching out to faculty for opportunities ( P = 0.01). There was a decrease in the perceived negative impact that attending medical schools without a home program will have on their abilities to pursue careers in plastic surgery ( P = 0.006). CONCLUSIONS: After the event, participants demonstrated an increase in their confidence in overcoming barriers and a decrease in their perceptions that attending an institution without a home program would negatively impact their ability to pursue plastic surgery. Initiatives focused on early exposure and recruitment of medical students may be important to promote accessibility and diversity within plastic surgery.

Improving Readability and Automating Content Analysis of Plastic Surgery Webpages With ChatGPT.

INTRODUCTION: The quality and readability of online health information are sometimes suboptimal, reducing their usefulness to patients. Manual evaluation of online medical information is time-consuming and error-prone. This study automates content analysis and readability improvement of private-practice plastic surgery webpages using ChatGPT. METHODS: The first 70 Google search results of "breast implant size factors" and "breast implant size decision" were screened. ChatGPT 3.5 and 4.0 were utilized with two prompts (1: general, 2: specific) to automate content analysis and rewrite webpages with improved readability. ChatGPT content analysis outputs were classified as hallucination (false positive), accurate (true positive or true negative), or omission (false negative) using human-rated scores as a benchmark. Six readability metric scores of original and revised webpage texts were compared. RESULTS: Seventy-five webpages were included. Significant improvements were achieved from baseline in six readability metric scores using a specific-instruction prompt with ChatGPT 3.5 (all P ≤ 0.05). No further improvements in readability scores were achieved with ChatGPT 4.0. Rates of hallucination, accuracy, and omission in ChatGPT content scoring varied widely between decision-making factors. Compared to ChatGPT 3.5, average accuracy rates increased while omission rates decreased with ChatGPT 4.0 content analysis output. CONCLUSIONS: ChatGPT offers an innovative approach to enhancing the quality of online medical information and expanding the capabilities of plastic surgery research and practice. Automation of content analysis is limited by ChatGPT 3.5's high omission rates and ChatGPT 4.0's high hallucination rates. Our results also underscore the importance of iterative prompt design to optimize ChatGPT performance in research tasks.
