Differences in the Reporting of Racial and Socioeconomic Disparities among Three Large National Databases for Breast Reconstruction

Background: Research derived from large-volume databases plays an increasing role in the development of clinical guidelines and health policy. In breast cancer research, the Surveillance, Epidemiology and End Results, National Surgical Quality Improvement Program, and Nationwide Inpatient Sample databases are widely used. This study aims to compare the trends in immediate breast reconstruction and identify the drawbacks and benefits of each database. Methods: Patients with invasive breast cancer and ductal carcinoma in situ were identified from each database (2005–2012). Trends of immediate breast reconstruction over time were evaluated. Patient demographics and comorbidities were compared. Subgroup analysis of immediate breast reconstruction use per race was conducted. Results: Within the three databases, 1.2 million patients were studied. Immediate breast reconstruction in invasive breast cancer patients increased significantly over time in all databases. A similar significant upward trend was seen in ductal carcinoma in situ patients. Significant differences in immediate breast reconstruction rates were seen among races; and the disparity differed among the three databases. Rates of comorbidities were similar among the three databases. Conclusions: There has been a significant increase in immediate breast reconstruction; however, the extent of the reporting of overall immediate breast reconstruction rates and of racial disparities differs significantly among databases. The Nationwide Inpatient Sample and the National Surgical Quality Improvement Program report similar findings, with the Surveillance, Epidemiology and End Results database reporting results significantly lower in several categories. These findings suggest that use of the Surveillance, Epidemiology and End Results database may not be universally generalizable to the entire U.S. population.

National and Regional Differences in 32,248 Postmastectomy Autologous Breast Reconstruction Using the Updated National Inpatient Survey

Background The incidence of breast cancer (BC) cases has increased significantly. The number of breast reconstruction (BR) procedures performed has mirrored this trend. Although implant-only procedures remain the most commonly used type of immediate BR, autologous techniques involving donor sites account for approximately 20%. The aim of this study was to assess national and regional trends in different types of autologous BR. Methods Using the Nationwide Inpatient Sample database (2008 to 2012), data on BC and mastectomy rates, type of autologous BR, and sociodemographics were obtained and analyzed. Furthermore, national and regional trends over time for autologous BR were plotted and analyzed. Results A total of 427,272 patients diagnosed with BC or at increased risk of BC were included in the study. A total of 343,163 (80.3%) patients underwent mastectomy and, within this group, 148,700 (43.3%) patients underwent immediate BR. Of these, 32,249 (21.7%) patients underwent an autologous BR (not solely implant based) and 118,258 (78.3%) implant-based BR. Most autologous BRs were performed in the Southern region (37.4%). When stratified into flap types, most pedicled transverse rectus abdominis muscle (TRAM), free TRAM, and other flaps were performed in the Northeast region, whereas most deep inferior epigastric perforator (DIEP) and latissimus dorsi (LD) flaps were performed in the Southern region. Subgroup analysis demonstrated a significant increasing trend for both LD and DIEP flaps, both nationally (P < 0.001) and regionally (P < 0.001). Pedicled TRAM and free TRAM reconstructions decreased significantly both on national and regional level. Conclusions Autologous BR demonstrated a significant positive trend over time in the Southern region (P < 0.001). The DIEP and LD flaps increased significantly over time, both nationally and regionally.

Reply: Medial Row Perforators Are Associated with Higher Rates of Fat Necrosis in Bilateral DIEP Flap Breast Reconstruction

Background: The purpose of this study was to evaluate perfusion-related complications in bilateral deep inferior epigastric perforator (DIEP) flap breast reconstruction based on perforator selection. Methods: A retrospective review of a prospectively maintained database was performed on all patients undergoing bilateral DIEP flap reconstruction at a single institution between 2004 and 2014. The hemiflaps were separated into three cohorts based on perforator location: lateral row only, medial row only, and medial plus lateral rows. Postoperative flap-related complications were compared and analyzed. Results: There were 728 total hemiflaps: 263 (36.1 percent) based on the lateral row, 225 (30.9 percent) based on the medial row, and 240 (33.0 percent) based on both the medial and lateral rows. The groups were well matched by perforator number and flap weight. Fat necrosis occurrence was significantly higher in flaps based solely on the medial row versus lateral row perforators (24.5 percent versus 8.2 percent; p < 0.001). There was no statistically significant difference in fat necrosis between flaps based only on the lateral row versus flaps based on both the medial and lateral rows (8.2 percent versus 11.6 percent; p = 0.203). Generally, within the same row, increasing the number of perforators decreased the incidence of fat necrosis. Conclusions: Perforator selection is critical for minimizing perfusion-related flap complications. In bilateral DIEP flaps, lateral row–based perforators result in significantly less fat necrosis than medial row–based perforators. The authors’ data suggest that the addition of a lateral row perforator to a dominant medial row perforator may decrease the risk of fat necrosis.

Oncoplastic breast surgery: Achieving oncological and aesthetic outcomes

Oncoplastic reconstruction allows more patients to become candidates for breast‐conserving surgery (BCS). Oncologic resection of a breast lesion is combined with plastic surgical techniques to improve aesthetic results. Choosing the best oncoplastic method is essential to optimize outcomes, improve cosmesis, and minimize postoperative complications. The aim of this study is to present a treatment algorithm incorporating oncoplastic techniques based on diagnosis, tumor size, tumor location, and breast size and shape.

Identifying Complications and Optimizing Consultations Following Trans-radial Arterial Access for Cardiac Procedures

BACKGROUND The radial approach to cardiac procedures has become increasingly common. Although previous studies have suggested a favorable risk profile, serious complications can occur. The purpose of this study is to examine the incidence, subsequent treatment, and outcome of all suspected significant neurovascular complications following transradial cardiac procedures at a large US hospital. METHODS We reviewed all patients who underwent a left heart catheterization, coronary angiogram, or percutaneous coronary intervention via the transradial approach at a single large academic medical center in the United States between 2010 and 2016. Consultations to the vascular and hand surgery services were examined to assess demographic variables, risk factors, presenting symptoms, subsequent treatment, and outcome of all serious complications. RESULTS A total of 9,681 radial access cardiac procedures were performed during the study period. Twenty-four cases (0.25%) were suspected to have major complications and subsequently received consults. A total of 18 complications were diagnosed, including 8 vascular injuries or perforations, 4 hematomas, 4 radial artery occlusions, 1 case of compartment syndrome, and 1 severe radial artery spasm. Of the complications noted, 3 (16.7%) required operative interventions, but all recovered neurovascular function. CONCLUSIONS Radial artery access for cardiac procedures has become increasingly common and has been associated with a low rate of major peripheral neurovascular complications. The majority (83.3%) of complications were successfully treated with a nonoperative management algorithm.

Abstract: Syndactyly: National Analysis of Trends in Epidemiology and Surgical Management from 1997–2012

Ten patients in the neurofibroma group and seven in the schwannoma groups responded to a post-operative survey. There were no significant differences for any responses. Both groups reported improvement in post-operative quality of life (p=0.7806), no regret with surgery (p=1.000), and a positive proclivity towards proceeding with surgery for potential future peripheral nerve tumors (p=0.8029).

Prospective, Double-Blind Evaluation of Umbilicoplasty Techniques Using Conventional and Crowdsourcing Methods

Background: Umbilical reconstruction is an important component of deep inferior epigastric perforator (DIEP) flap breast reconstruction. This study evaluated the aesthetics of three different umbilical reconstruction techniques during DIEP flap breast reconstruction. Methods: From January to April of 2013, a total of 29 consecutive patients undergoing DIEP flap breast reconstruction were randomized intraoperatively to receive one of three umbilicoplasty types: a diamond, an oval, or an inverted V incision. Independent plastic surgeons and members of the general public, identified using an online “crowdsourcing” platform, evaluated aesthetic outcomes in a blinded fashion. Reviewers were shown postoperative photographs of the umbilicus of all patients and a four-point Likert scale was used to rate the new umbilicus on the size, scar formation, shape, localization, and overall appearance. Results: Results for the focus group of independent plastic surgeons and 377 members of the public were retrieved (n = 391). A total of 10 patients (34.5 percent) were randomized into having the diamond incision, 10 (34.5 percent) had the oval incision, and nine (31.0 percent) had the inverted V incision. Patients were well matched in terms of overall characteristics. The general public demonstrated a significant preference for the oval incision in all five parameters. There was no preference identified among surgeons. Conclusion: This study provides evidence that a sample of the U.S. general public prefers the aesthetics of the oval umbilicoplasty incision, which contrasted with the lack of preference identified within this focus group of plastic surgeons. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

Prevalence of psychiatric comorbidities among women undergoing free tissue autologous breast reconstruction

Autologous breast reconstruction (BR) can be a stressful life event. Therefore, women undergoing mastectomy and autologous BR are required to have sufficient coping mechanisms. Although mental health problems are widespread, information regarding the prevalence of psychiatric diagnosis among these patients is scarce.
