Free flap reconstruction of elbow soft tissue defects: Lessons learned from 15 years of experience.

BACKGROUND: The elbow is a complex joint that is vital for proper function of the upper extremity. Reconstruction of soft tissue defects over the joint space remains challenging, and outcomes following free tissue transfer remain underreported in the literature. The purpose of this analysis was to evaluate the rate of limb salvage, joint function, and clinical complications following microvascular free flap coverage of the elbow. METHODS: This retrospective case series utilized surgical logs of the senior authors (Stephen J Kovach and L Scott Levin) to identify patients who underwent microvascular free flap elbow reconstruction between January 2007 and December 2021. Patient demographics and medical history were collected from the medical chart. Operative notes were reviewed to determine the type of flap procedure performed. The achievement of definitive soft tissue coverage, joint function, and limb salvage status at 1 year was determined from postoperative visit notes. RESULTS: Twenty-one patients (14 male, 7 female, median age 43) underwent free tissue transfer for coverage of soft tissue defects of the elbow. The most common indication for free tissue transfer was traumatic elbow fracture with soft tissue loss (n = 12, [57%]). Among the 21 free flaps performed, 71% (n = 15) were anterolateral thigh flaps, 14% (n = 3) were latissimus dorsi flaps, and 5% (n = 1) were transverse rectus abdominis flaps. The mean flap size was 107.5 cm2. Flap success was 100% (n = 21). The following postoperative wound complications were reported: surgical site infection (n = 1, [5%]); partial dehiscence (n = 5, [24%]); seroma (n = 2, [10%]); donor-site hematoma (n = 1, [5%]); and delayed wound healing (n = 5, [24%]). At 1 year, all 21 patients achieved limb salvage and definitive soft tissue coverage. Of the 17 patients with functional data available, 47% (n = 8) had regained at least 120 degrees of elbow flexion/extension. All patients had greater than 1 year of follow-up. CONCLUSION: Microvascular free flap reconstruction is a safe and effective method of providing definitive soft tissue coverage of elbow defects, as evidenced by high rates of limb salvage and functional recovery following reconstruction.

T-line Hernia Mesh Repairs of Large Umbilical Hernias: Technique and Short-term Outcomes.

Background: The T-line hernia mesh is a synthetic, polypropylene mesh specifically designed to prevent anchor point failure by evenly distributing tension through mesh suture extensions. This case series illustrates the first clinical application of the T-line mesh for umbilical hernia repair (UHR). Methods: This study is a retrospective, consecutive cases series of all adult patients presenting to a single surgeon with symptomatic umbilical hernia requiring surgical repair using the T-line hernia mesh. Patient demographics, surgical details, and 30-day postoperative complications were collected. Descriptive statistics were computed in Microsoft Excel (Redmond, Va.). Results: Three patients presented for UHR. All three patients were obese with mean body mass index of 37.5 ±â€…6.6. Two patients were former smokers, and two had presented after hernia recurrence. The average defect size was 80.1 cm2 ± 94.0 cm2. Two patients had UHR with onlay mesh placement, whereas one had a transversus abdominus release followed by retrorectus mesh placement. The average mesh size was 192.3 cm2 ± 82.5 cm2. All three cases were classified as clean. There were no intraoperative complications. No patients experienced 30-day postoperative complications or recurrence. Conclusions: We present a case series of three patients presenting with large, symptomatic umbilical hernias who underwent UHR with T-line hernia mesh reinforcement without short term complications or hernia recurrence at last follow-up.

Machine learning analysis of online patient questions regarding breast reconstruction.

BACKGROUND: Social media has become a dominant educational resource for breast reconstruction patients. Rather than passively consuming information, patients interact directly with other users and healthcare professionals. While online information for breast reconstruction has been analyzed previously, a robust analysis of patient questions on online forums has not been conducted. In this study, the authors used a machine learning approach to analyze and categorize online patient questions regarding breast reconstruction. METHODS: Realself.com was accessed and questions pertaining to breast reconstruction were extracted. Data collected included the date of question, poster's location, question header, question text, and available tags. Questions were analyzed and categorized by two independent reviewers. RESULTS: 522 preoperative questions were analyzed. Geographic analysis is displayed in Figure 1. Questions were often asked in the pre-mastectomy period (38.3%); however, patients with tissue expanders currently in place made up 28.5%. Questions were often related to reconstructive methods (23.2%), implant selection (19.5%), and tissue expander concerns (16.7%). Questions asked in the post-lumpectomy period were significantly more likely to be related to insurance/cost and reconstructive candidacy (p < 0.01). The "Top 6″ patient questions were determined by machine learning analysis, and the most common of which was "Can I get good results going direct to implant after mastectomy?" CONCLUSIONS: Analysis of online questions provides valuable insights and may help inform our educational approach toward our breast reconstruction patients. Our findings suggest that questions are common throughout the reconstructive process and do not end after the initial consultation. Patients most often want more information on the reconstructive options, implant selection, and the tissue expansion process.

Navigating the Ethical Landmines of ChatGPT: Implications of Intelligent Chatbots in Plastic Surgery Clinical Practice.

ChatGPT is a cutting-edge language model developed by OpenAI with the potential to impact all facets of plastic surgery from research to clinical practice. New applications for ChatGPT are emerging at a rapid pace in both the scientific literature and popular media. It is important for clinicians to understand the capabilities and limitations of these tools before patient-facing implementation. In this article, the authors explore some of the technical details behind ChatGPT: what it is, and what it is not. As with any emerging technology, attention should be given to the ethical and health equity implications of this technology on our plastic surgery patients. The authors explore these concerns within the framework of the foundational principles of biomedical ethics: patient autonomy, nonmaleficence, beneficence, and justice. ChatGPT and similar intelligent conversation agents have incredible promise in the field of plastic surgery but should be used cautiously and sparingly in their current form. To protect patients, it is imperative that societal guidelines for the safe use of this rapidly developing technology are developed.

OPTN/SRTR 2021 Annual Data Report: Vascularized Composite Allograft.

Year 2020 marked the first OPTN/SRTR Annual Data Report that included a chapter on vascularized composite allograft (VCA), which encompassed reviews of data collected between 2014 (when VCA was included in the Final Rule) and 2020. The present Annual Data Report shows that the number of VCA recipients in the United States continues to be small and trended downward in 2021. While data continue to be limited by sample size, trends continue to show a predominance in White, young/middle-aged, male recipients. Similar to the 2020 report, eight uterus and one non-uterus VCA graft failures were reported from 2014 through 2021. Critical to advancement of VCA transplantation will be the standardization of definitions, protocols, and outcome measures for the different VCA types. Like intestinal transplants, it is likely that VCA transplants will be concentrated and performed at referral transplant centers.

Breast Implant-Associated Anaplastic Large-Cell Lymphoma: Updated Systematic Review and Analysis of Treatment Strategies.

BACKGROUND: Although guidelines have been published on treatment of breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL), there has been no comprehensive analysis of BIA-ALCL treatment variation based on the available literature. The authors sought to assess current treatment strategies of BIA-ALCL relative to current guidelines. METHODS: Database searches were conducted in June of 2020. Included articles were case reports and case series with patient-level data. Collected variables included clinicopathologic features, implant characteristics, diagnostic tests, ALCL characteristics, treatment, and details of follow-up and outcome. Treatment data from before and after 2017 were compared with National Cancer Center Network guidelines. RESULTS: A total of 89 publications were included and 178 cases of BIA-ALCL were identified. Most patients presented with seroma ( n = 114, 70.4 percent), followed by a mass ( n = 14, 8.6 percent), or both ( n = 23, 14.2 percent). Treatment included en bloc capsulectomy of the affected implant in 122 out of 126 cases with treatment details provided (96.8 percent). Radiation therapy was given in 38 cases (30.2 percent) and chemotherapy was given in 71 cases (56.3 percent). Practitioners used less chemotherapy for local disease after treatment guideline publication in 2017 ( p < 0.001), whereas treatment for advanced disease remained unchanged ( p = 0.3). There were 10 recurrences and eight fatalities attributable to BIA-ALCL, which were associated with advanced presentation (29 versus 2.1 percent; OR, 19.4; 95 percent CI, 3.9 to 96.3; p < 0.001). CONCLUSIONS: BIA-ALCL remains a morbid but treatable condition. Current guidelines focus treatment for local disease and reduce nonsurgical interventions with radiation or chemotherapy. Patients presenting with advanced BIA-ALCL experience higher rates of recurrence and mortality.

An Ounce of Prediction is Worth a Pound of Cure: Risk Calculators in Breast Reconstruction.

Preoperative risk calculators provide individualized risk assessment and stratification for surgical patients. Recently, several general surgery-derived models have been applied to the plastic surgery patient population, and several plastic surgery-specific calculators have been developed. In this scoping review, the authors aimed to identify and critically appraise risk calculators implemented in postmastectomy breast reconstruction. Methods: A systematic review of the literature was conducted. Included studies described the development of a novel risk calculator, or validation of an existing calculator, in postmastectomy breast reconstruction. Results: In total, 4641 studies met criteria for title and abstract screening. Forty-seven were eligible for full-text review, and 28 met final inclusion criteria. The most common risk calculators included the Breast Reconstruction Risk Assessment score (n = 6 studies), modified frailty index (n = 3), Caprini score (n = 3), and ACS NSQIP calculator (n = 2). Calculators were applied to institutional data (n = 17), NSQIP (n = 6), and Tracking Outcomes in Plastic Surgery (n = 1) databases. Predicted outcomes included general postoperative complications (n = 17), venous thromboembolism/pulmonary embolism (n = 4), infection (n = 2), and patient reported outcomes (n = 2). Model accuracy was reported in 18 studies, and it varied significantly (accurate risk calculator 0.49-0.85). Conclusions: This is the first study to provide a systematic review of available risk calculators for breast reconstruction. Models vary significantly in their statistical basis, predicted outcomes, and overall accuracy. Risk calculators are valuable tools that may aid in individualized risk assessments, preoperative counseling, and expectation management in breast reconstruction.

Does the Geographical Distribution of Facial Trauma Surgeons Correspond to Facial Trauma Burden? A Nationwide Population-Level Analysis.

ABSTRACT: It is unknown if craniofacial trauma services are inequitably distributed throughout the US. The authors aimed to describe the geographical distribution of craniofacial trauma, surgeons, and training positions nationwide. State-level data were obtained on craniofacial trauma admissions, surgeons, training positions, population, and income for 2016 to 2017. Normalized densities (per million population [PMP]) were ascertained. State/ regional-level densities were compared between highest/lowest. Risk-adjusted generalized linear models were used to determine independent associations. There were 790,415 craniofacial trauma admissions (x? = 2330.6 PMP), 28,004 surgeons (x? = 83.5 PMP), and 746 training positions (x? = 1.9 PMP) nationwide. There was significant state-level variation in the density PMP of trauma (median 1999.5 versus 2983.5, P   <  0.01), surgeon (70.8 versus 98.8, P  < 0.01), training positions (0 versus 3.4, P  < 0.01) between lowest/highest quartiles. Surgeon distribution was positively associated with income and training positions density ( P  < 0.01). Subanalysis revealed that there was an increase of 6.7 plastic and reconstructive surgeons/PMP for every increase of 1000 trauma admissions/PMP ( P  < 0.01). There is an uneven state-level distribution of facial trauma surgeons across the US associated with income. Plastic surgeon distribution corresponded closer to craniofacial trauma care need than that of ENT and OMF surgeons. Further work to close the gap between workforce availability and clinical need is necessary.

Short- and Long-Term Outcomes following Severe Traumatic Lower Extremity Reconstruction: The Value of an Orthoplastic Limb Salvage Center to Racially Underserved Communities.

BACKGROUND: Previous studies have demonstrated that nonwhite race and disadvantaged socioeconomic status negatively impact outcomes following lower extremity reconstruction. The authors sought to characterize differences in outcomes between racial groups in patients necessitating traumatic lower extremity reconstruction at an orthoplastic limb salvage center. METHODS: A retrospective review between 2002 and 2019 was conducted of patients who underwent free flap lower extremity reconstruction at an orthoplastic limb salvage center. Patient demographics were identified, and permanent addresses were used to collect census data. Short-term complications and long-term functional status were recorded. RESULTS: One hundred seventy-three patients underwent lower extremity reconstruction and met inclusion criteria. Among all three groups, African American patients were more likely to be single (80 percent African American versus 49 percent Caucasian and 29.4 percent other; p < 0.05) and had significantly lower rates of private insurance compared with Caucasian patients (25 percent versus 56.7 percent; p < 0.05). African American patients demonstrated no significant differences in total flap failure (4.9 percent versus 8 percent and 5.6 percent; p = 0.794), reoperations (10 percent versus 5.8 percent and 16.7 percent; p = 0.259), and number of readmissions (2.4 versus 2.0 and 2.1; p = 0.624). Chronic pain management (53.3 percent versus 44.2 percent and 50 percent; p = 0.82), full weight-bearing status (84.2 percent versus 92.7 percent and 100 percent; p = 0.507), and ambulation status (92.7 percent versus 100 percent and 100 percent; p = 0.352) were similar among groups. CONCLUSIONS: Outcomes are equivalent between racial groups presenting to an orthoplastic limb salvage center for lower extremity reconstruction. The postoperative rehabilitation strategies, follow-up, and overall support that an orthoplastic limb salvage center ensures may lessen the impact of socioeconomic disparities in traumatic lower extremity reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.

Outcomes of Poly-4-hydroxybutyrate Mesh in Ventral Hernia Repair: A Systematic Review and Pooled Analysis.

Within the past decade, poly-4-hydroxybutyrate (P4HB) biosynthetic mesh has been introduced as a potential alternative to traditional biologic and synthetic mesh in ventral hernia repair (VHR). The aim of this study was to systematically assess clinical outcomes with the P4HB in VHR. METHODS: A literature search identified all articles published in 2000 involving the use of P4HB in VHR. Descriptive statistics were used to synthesize collective data points, including postoperative outcomes. A pooled analysis of postoperative outcomes was performed using chi-square test and Fisher exact test. RESULTS: Across 7 studies, the P4HB was used in 453 patients. The mean rate of surgical site infection (SSI) was 6.8% (31/453), reoperation 10.7% (30/281), and recurrence 9.1% (41/453). At an average follow-up of 26.8 months, the incidence of recurrence was 10.4% (28/270). Onlay was significantly associated with increased recurrence (14.2% versus 4.4%, P = 0.001). Among sublay placements, there was no difference in recurrence in clean (Center for Disease Control [CDC] 1) or contaminated (CDC >1) wounds (2.7% versus 6.1%, P = 0.585), but contaminated wounds were associated with increased SSI (2.7% versus 15.2%, P = 0.028). Ventral Hernia Working Group grade 2 and 3 did not have different incidences of recurrence (8.0% versus 5.1%, P = 0.526) nor SSI (5.1% versus 14.6%, P = 0.265). CONCLUSIONS: Overall, clinical outcomes of the P4HB mesh in VHR are acceptable. The P4HB mesh serves as a reliable alternative to traditional synthetic and biologic mesh across a range of defect characteristics and patient health conditions. Further research is needed to better understand the conditions in which it may provide a clinical benefit over traditional mesh types.

Beyond the Hernia Repair: A Review of the Insurance Coverage of Critical Adjuncts in Abdominal Wall Reconstruction.

The prevalence of complex abdominal wall defects continues to rise, which necessitates increasingly sophisticated medical and surgical management. Insurance coverage for reconstructive surgery varies due to differing interpretations of medical necessity. The authors sought to characterize the current insurance landscape for a subset of key adjunctive procedures in abdominal wall reconstruction, including component separation and simultaneous ventral hernia repair with panniculectomy (SVHR-P) or abdominoplasty (SVHR-A), and synthesize a set of reporting recommendations based on insurer criteria. METHODS: Insurance companies were selected based on their national and state market share. Preauthorization criteria, preauthorization lists, and medical/clinical policies by each company for component separation, SVRH-P, and SVRH-A were examined. Coverage criteria were abstracted and analyzed. RESULTS: Fifty insurance companies were included in the study. Only 1 company had clear approval criteria for component separation, while 38 cover it on a case-by-case basis. Four companies had clear approval policies for SVHR-P, 4 cover them on an individual case basis, and 28 flatly do not cover SVHR-P. Similarly, 3 companies had clear approval policies for SVHR-A, 6 cover them case by case, and 33 do not cover SVHR-A. CONCLUSIONS: Component separation and soft tissue contouring are important adjunctive AWR procedures with efficacy supported by peer-reviewed literature. The variability in SVHR-P and SVHR-A coverage likely decreases access to these procedures even when there are established medical indications. The authors recommend standardization of coverage criteria for component separation, given that differing interpretations of medical necessity increase the likelihood of insurance denials.
