Conversion from Alloplastic to Autologous Breast Reconstruction: What Are the Inciting Factors?

Introduction: Failure of alloplastic breast reconstruction is an uncommon occurrence that may result in abandonment of reconstructive efforts or salvage with conversion to autologous reconstruction. The purpose of this study was to identify factors that predict failure of alloplastic breast reconstruction and conversion to autologous reconstruction. Methods: A retrospective chart review was conducted of patients who underwent mastectomy and immediate alloplastic breast reconstruction between 2008 and 2019. Inclusion criteria included patients 18 years or older who underwent initial alloplastic reconstruction with a minimum of 3-year follow-up. Data collected included age, body mass index, cancer type, surgical characteristics, neo/adjuvant treatment details, and complications. Results were analyzed using Fischer's exact test, t-test, and multivariate logistic regression. Results: A total of 234 patients met inclusion criteria. Of those, 23 (9.8%) required conversion from alloplastic to autologous reconstruction. Converted patients had a mean age of 50.1 ± 8.5. The time from initial alloplastic reconstruction to conversion was 30.7 months. The most common reasons for conversion included soft tissue deficiency (48%), infection (30%), and capsular contracture (22%). Patients were converted to deep inferior epigastric perforator flap (DIEP; 52%), latissimus dorsi flap with implant (26%), and DIEP with implant (22%). Multivariate logistic regression modeling identified radiation (OR 8.4 [CI = 1.7-40.1]) and periprosthetic infection (OR 14.6 [CI = 3.4-63.8]) as predictors for conversion. Conclusions: Among patients undergoing mastectomy with immediate alloplastic breast reconstruction, those treated with radiation have 8.4 greater odds of conversion and those with a periprosthetic infection have 14.6 greater odds for conversion to an autologous reconstruction.

Introduction : L'échec d'une reconstruction mammaire alloplastique est un événement peu fréquent qui peut aboutir à un abandon des efforts de reconstruction ou à une solution de secours avec une conversion en reconstruction autologue. L'objectif de cette étude était d'identifier les facteurs prédisant l'échec de la reconstruction mammaire alloplastique et sa conversion en reconstruction autologue. Méthodes : Une étude rétrospective a été menée sur les dossiers de patientes ayant subi une mastectomie suivie d'une reconstruction mammaire alloplastique immédiate entre 2008 et 2019. Les critères d'inclusion étaient notamment des patientes âgées d'au moins 18 ans ayant subi une reconstruction alloplastique initiale avec un suivi minimum de 3 ans. La collecte de données a inclus : l'âge, l'indice de masse corporelle (IMC), le type de cancer, les caractéristiques chirurgicales, les détails sur le traitement adjuvant/néoadjuvant et les complications. Les résultats ont été analysés à l'aide du test t exact de Fischer, un test t et une analyse de régression logistique multifactorielle. Résultats : Un total de 234 patientes a satisfait les critères d'inclusion. Parmi ces patientes, 23 (9,8%) ont nécessité la conversion de la reconstruction alloplastique en reconstruction autologue. Les patientes « converties ¼ avaient un âge moyen de 50,1 ± 8,5 ans. Le délai séparant la reconstruction alloplastique initiale et la conversion était de 30,7 mois. Les motifs les plus fréquents de conversion étaient une déficience des tissus mous (48%), une infection (30%) et la formation d'une coque (22%). Les techniques de conversion utilisées étaient la technique dite DIEP ou AEIP (artère épigastrique inférieure profonde, 52%), un lambeau du grand dorsal avec implant (26%), et la technique DIEP avec implant (22%). Une modélisation d'analyse de régression logistique multifactorielle a identifié les facteurs prédictifs de conversion suivants : irradiation (rapport de cotes = 8,4 [IC = 1,7-40,1]) et l'infection périprothétique (RC = 14,6 [IC = 3,4 à 63,8]). Conclusions : Parmi les patientes subissant une mastectomie avec reconstruction mammaire alloplastique immédiate, celles qui ont reçu une radiothérapie avaient un risque de conversion 8,4 fois plus grand et les patientes ayant une infection périprothétique avaient un risque 14,6 fois plus grand de conversion en reconstruction autologue.

Gender imbalance amongst promotion and leadership in academic surgical programs in Canada: A cross-sectional Investigation.

BACKGROUND: Women are underrepresented at higher levels of promotion or leadership despite the increasing number of women physicians. In surgery, this has been compounded by historical underrepresentation. With a nation-wide focus on the importance of diversity, our aim was to provide a current snapshot of gender representation in Canadian universities. METHODS: This cross-sectional online website review assessed the current faculty listings for 17 university-affiliated academic surgical training departments across Canada in the 2019/2020 academic year. Gender diversity of academic surgical faculty was assessed across surgical disciplines. Additionally, gender diversity in career advancement, as described by published leadership roles, promotion and faculty appointment, was analyzed. RESULTS: Women surgeons are underrepresented across Canadian surgical specialties (totals: 2,689 men versus 531 women). There are significant differences in the gender representation of surgeons between specialties and between universities, regardless of specialty. Women surgeons had a much lower likelihood of being at the highest levels of promotion (OR: 0.269, 95% CI: 0.179-0.405). Men surgeons were statistically more likely to hold academic leadership positions than women (p = 0.0002). Women surgeons had a much lower likelihood of being at the highest levels of leadership (OR: 0.372, 95% CI: 0.216-0.641). DISCUSSION: This study demonstrates that women surgeons are significantly underrepresented at the highest levels of academic promotion and leadership in Canada. Our findings allow for a direct comparison between Canadian surgical subspecialties and universities. Individual institutions can use these data to critically appraise diversity policies already in place, assess their workforce and apply a metric from which change can be measured.

The Cost of Burn Transfers: A Retrospective Review of 7 Years of Admissions to a Regional Burn Center.

The transport of thermally injured patients can involve significant costs; however, not all thermally injured patients necessitate transfer to a burn center. The purpose of this study was to review transfers to an American Burn Association-verified regional burn center to determine whether the transfers were necessary and the cost associated with unnecessary transfers. A retrospective chart review identified 707 patients transferred to an American Burn Association-verified burn center with an acute burn injury during a 7-year period. For the purposes of this study, "unnecessary transfer" was defined as any patient admitted fewer than 7 days who did not undergo operative intervention. Transfer cost estimates were based on records from regional land paramedic and land and air medical transport services. In total, 27.3% of transfers were potentially "unnecessary transfers," with an associated cost of approximately $227,396.93 (18.9% of total transfer costs in study). Average unnecessary transfer cost varied by method of transport: land ambulance (n = 130) $285.72, helicopter (n = 27) $4,136.34, and airplane (n = 15) $4,908.67. The transfer of thermally injured patients is associated with significant cost. Unnecessary transfers represent an inefficient use of a limited resource in an already strained healthcare system. The findings of this study suggest that further initiatives should be explored to ensure the appropriate transfer of thermally injured patients.
