Trends in American Plastic Surgery Procedures (2005-2019): Observing the Growth Rate of Maxillofacial Surgery and Cosmetic Minimally Invasive Procedures in ASPS Data.

This study explores the dynamic changes in plastic surgery practices, focusing on the growth rates across different subcategories, particularly highlighting the trends in the United States. To analyze evolving trends in plastic surgery using statistical methods, providing insights into the changes and growth patterns in various segments over time. Utilizing data from 2005 to 2019 from the American Society of Plastic Surgeons, the authors, conducted a comprehensive statistical analysis using the SPSS program to investigate trends in plastic surgery procedures. Our analysis revealed no significant differences in year-on-year growth rates between cosmetic and reconstructive surgery. However, in reconstructive surgery subcategories, maxillofacial surgery showed the highest mean growth rate at 11.61%, though this was not statistically significant. In cosmetic minimally invasive procedures, soft tissue filler injections and botulinum toxin A injections experienced notably higher growth trends compared with microdermabrasion. The findings suggest that practitioners considering a career in plastic surgery should not focus solely on choosing between reconstructive and cosmetic surgery. Recognizing substantial growth in cosmetic minimally invasive procedures, especially botulinum toxin A injections and fillers, is vital for making informed career decisions.

Plastic and Reconstructive Surgery in the Wake of the Eid al-Adha: A Single-Center, Five-Year Investigation

Abnormal Pathology Following Vaginal Hysterectomy for Pelvic Organ Prolapse Repair.

Objective: Uterine-sparing surgery for pelvic organ prolapse (POP) repair has shown good results, but the potential negative implications of leaving the uterus in place are yet to be fully defined. We aimed to assess the risk of unanticipated abnormal gynecological pathology at the time of reconstructive pelvic surgery. Methods: A retrospective consecutive case series including women who underwent vaginal hysterectomy for POP repair at a tertiary medical center in 2006-2020. All patients were offered a free Pap smear test at the age of 65 years as part of a national screening program. Transvaginal ultrasound was routinely performed preoperatively. Standard 3 pedicle hysterectomy was performed with/without bilateral salpingo-oophorectomy (BSO). Results: The study comprised 462 women of mean age 63 ± 9.3 years without previous known malignant or premalignant pathology. Benign pathology was observed in 286 patients (61.9%). Endometrial malignancy was found in three patients (0.7%) and significant premalignant pathology in 15 patients (3.2%), including cervical intraepithelial neoplasia stage 2-3 in seven patients (1.5%) and complex hyperplasia with atypia in eight patients (1.7%). All these pathologies were found in postmenopausal women. None had preoperative clinical symptoms or endometrial thickness of ≥5 mm on preoperative ultrasound. In the 35 patients after BSO, adnexal findings were normal (77.2%) or benign (22.8%). Conclusions: Premenopausal women with uterovaginal prolapse and normal preoperative evaluation have a minimal risk of significant abnormal uterine pathology. In postmenopausal women, the risk of unanticipated malignant uterine pathology is 0.7% and 3.2% for significant premalignancy.

Abstract PO3-02-14: The Safety of Breast Reconstruction: The Impact of Breast Reconstruction Surgery on Postoperative Adjuvant Therapy for Breast Cancer

Abstract Background: Postoperative adjuvant therapy is very important in treating breast cancer, and increasing numbers of patients are undergoing immediate breast reconstruction (IBR) at the same time as breast cancer surgery. However, the impact of breast reconstruction surgery on adjuvant therapy is controversial. In this multicenter cohort study led by the Japanese Breast Cancer Society, we examined the impact of reconstructive surgery on postoperative adjuvant therapy in breast cancer patients who underwent IBR. Methods: We examined the association between adjuvant therapy and complications of reconstructive surgery in 4726 patients with primary breast cancer who underwent IBR during the period from January 1, 2008 to December 31, 2016. Statistical analysis employed the χ2 test. Results: Of the 995 patients who received adjuvant chemotherapy, the median time from the date of surgery to the start of chemotherapy was 51.0 days, with 63 patients (6.2%) starting more than 90 days after surgery. Eighty-four IBR complications required surgery (8.4%), including infections and tissue expander (TE) removal. Of the 63 patients for whom chemotherapy was initiated 90 days or more after surgery, 10 patients (15.9%) had complications requiring surgery, significantly more than the 74 patients (7.9%) in the < 90 days group (P = 0.028). Post-mastectomy radiation therapy (PMRT) was performed after breast cancer surgery in 359 cases: 69 cases received autologous tissue irradiation, 46 TE irradiation, 241 silicone breast implant (SBI) irradiation, and 3 artificial material removal before irradiation. 5 cases given autologous tissue irradiation and 26 receiving artificial material irradiation (22 of whom the artificial material was removes) required surgery within 1 year after the cancer surgery due to complications of IBR. There was no significant difference in the frequency of complications requiring surgery between autologous tissue irradiation and artificial material irradiation (P=0.632). There were 33 complications (9.2%) requiring surgery in the irradiated group, significantly more than the 129 cases (3.0%) in the non-irradiated group (P< 0.001). Conclusion: Adjuvant chemotherapy was generally not delayed, but complications requiring surgery related to IBR were more frequent in those with delay beyond 90 days, suggesting that postoperative complications from breast reconstruction may have influenced the delay in initiating chemotherapy. Therefore, in cases for whom postoperative chemotherapy is anticipated, complications from breast reconstruction may have impacted outcomes, making preoperative risk assessment even more important. There was no difference in the frequency of reconstructive complication surgery according to whether autologous tissue irradiation or artificial material irradiation had been used, but further investigation is needed.

Abstract PO3-28-02: BODY-IMAGE DISTRESS IN BREAST CANCER SURVIVORS AND THEIR EVALUATION OF MEDICAL TATTOOING FOLLOWING SURGERY

Abstract A review of the literature reveals a high incidence of body-image distress among breast cancer survivors who have undergone surgery, which is a natural response to the significant changes in their appearance. Reconstructive surgery, utilizing implants or flaps, may be employed to restore breast size and shape. Medical tattooing can recreate the nipple-areola complex and decorative appliques can conceal scars and skin color variations. Both reconstructive surgery and medical tattoos are associated with patient-reported satisfaction, yet further research is necessary to understand their combined impact on body-image distress. To investigate this, a survey was distributed among national breast cancer support groups and advocacy organizations, yielding 207 responses from individuals meeting the study's criteria. The participants were categorized into two groups: those who received post-surgical medical tattoos (n = 61) and those who did not (n = 146). The study also examined how participants evaluated the cosmetic and decision satisfaction of patients who made various surgical and cosmetic intervention choices. This was accomplished by having participants rate images of patients who had received three types of intervention: mastectomy and reconstruction only, mastectomy and medical tattooing only, and mastectomy, reconstruction, and medical tattooing. Using linear regression and multilevel modeling that controlled for demographic and clinical factors associated with body-image distress, the findings demonstrated that participants with medical tattoos reported significantly lower levels of body-image distress, depressive symptoms, and perceived stress compared to those without medical tattoos. Furthermore, participants rated images of patients who underwent both reconstruction and medical tattooing post-mastectomy as having significantly higher cosmetic and decision satisfaction ratings than images of patients who received reconstruction or medical tattooing alone. This research expands on our understanding of body-image distress in survivors as a multidimensional construct and may serve to indicate potential means for intervention. Enhancing our understanding of how breast cancer treatment and surgery affects survivors' body-image distress may aid healthcare professionals in offering additional psychoeducation and recommendations. Furthermore, presenting information about medical tattooing as a complementary cosmetic option early in the treatment process allows patients the opportunity to consider it within the context of their overall treatment plan.

Abstract PO3-22-08: Impact of Zip Code-Based Income on Reconstructive Method and Outcomes in Mutation-Positive Breast Cancer Patients

Abstract Background: In the United States, 13% of women develop invasive breast cancer, with certain genetic mutations increasing the risk. Genetic screening is costly and burdensome for patients, particularly those from lower socioeconomic backgrounds. Moreover, lower income (LI) patients face barriers in accessing healthcare and have lower rates of breast reconstruction. This study aims to examine the impact of socioeconomic status, as indicated by ZIP code median income, on the type of breast surgery, reconstructive technique, and perioperative outcomes among mutation-positive (M+) patients. Methods: A multicenter retrospective cohort study included patients with a genetic predisposition for breast cancer and undergoing breast and reconstructive surgery between January 2016 and October 2022. Patient demographics, history, operative details, and postoperative outcomes were collected. Patient ZIP codes were cross-referenced with the American Community Survey to determine the median household income, which served as a proxy for the patient-specific household income. Four distinct income quartiles were established: quartile 1 (Q1) = $37,045-$81,586 (“LI”); quartile 2 (Q2) = $81,587-$103,703; quartile 3 (Q3) = $103,704-$129,768; and quartile 4 (Q4) = $129,769-$213,724. Results: Among the 170 patients analyzed, 42 (24.7%) were in Q1, 42 (24.7%) in Q2, 44 (25.9%) in Q3, and 42 (24.7%) in Q4. Most patients had BRCA1 (n=73, 42.9%), BRCA2 (n=68, 40.0%), PALB2 (n=11,6.5%), or CHEK2 (n=8, 64.7%) mutations, and underwent prophylactic mastectomy without evidence of breast cancer (n=119, 70.0%). Mean age and body mass index (BMI) were 41±16 years and 25.0±7.5 kg/m2, respectively. There was a significant association between patient race and income (p< 0.0001), such that 30.1% of White patients were in Q4 (vs. 8.3% of Black patients), compared to 38.9% of Black patients in Q1 (vs.19.0% of White patients). LI was significantly associated with higher BMI (p=0.0083) and obesity rates (p=0.0080). Nipple-sparing mastectomy (NSM) (n=103, 60.6%) was the most frequent surgical approach, followed by skin-sparing mastectomy (SSM) (n=42, 24.7%), simple mastectomy (n=13, 7.6%), lumpectomy (n=4, 2.4%), and radical mastectomy (n=4, 2.4%). Patients in Q3 underwent NSM significantly more often than those in Q1 (p=0.0080). Tissue expander (n=73, 42.9%) was the most common reconstruction method. 34.7% of patients (n=59) experienced postoperative complications. Short-term (< 30 days postoperatively) complications included delayed wound healing (n=22, 12.9%), surgical site infection (n=16, 9.4%), dehiscence (n=12, 7.1%), cellulitis (n=10, 5.9%), seroma (n=9, 5.3%) and hematoma (n=9, 4.7%). Long term (≥30 days postoperatively) complications included mastectomy flap necrosis (n=22, 12.9%), total reconstructive failure (n=8, 4.7%), and red breast syndrome (n=2, 1.2%). There was no significant association between income level and incidence of complications (p >0.05). Income level significantly correlated with cancer recurrence, as patients in Q2 (n=0, 0.0%) and Q4 (n=1, 2.4%) had significantly lower recurrence rates compared to Q1 (n=6, 14.3%) (p=0.0140). Of the 30.0% of patients with diagnosis of cancer at DOS, 66.7% (n=34) of patients had ductal carcinoma in situ (DCIS). Eleven of these patients were in Q1, five in Q2, six in Q3, and twelve in Q4 (p=0.259). Conclusion: LI M+ patients had lower NSM rates than higher income patients, despite similar rates of prophylactic mastectomies, possibly due to perceived costs of increased follow-up care. Moreover, LI patients experienced higher cancer recurrence, despite similar incidences of equivalent cancer subtypes at presentation, likely reflecting differences in post-diagnostic care and morbidity. These findings highlight the need to address financial barriers and ensure equitable access to comprehensive care for M+ patients of all income strata.

Postoperative Long-Term Monitoring of Mechanical Characteristics in Reconstructed Soft Tissues Using Biocompatible, Immune-Tolerant, and Wireless Electronic Sutures.

Accurate postoperative assessment of varying mechanical properties is crucial for customizing patient-specific treatments and optimizing rehabilitation strategies following Achilles tendon (AT) rupture and reconstruction surgery. This study introduces a wireless, chip-less, and immune-tolerant in vivo strain-sensing suture designed to continuously monitor mechanical stiffness variations in the reconstructed AT throughout the healing process. This innovative sensing suture integrates a standard medical suturing thread with a wireless fiber strain-sensing system, which incorporates a fiber strain sensor and a double-layered inductive coil for wireless readout. The winding design of Au nanoparticle-based fiber electrodes and a hollow core contribute to the fiber strain sensor's high sensitivity (factor of 6.2 and 15.1 pF for revised sensitivity), negligible hysteresis, and durability over 10,000 stretching cycles. To ensure biocompatibility and immune tolerance during extended in vivo periods, an antibiofouling lubricant layer was applied to the sensing suture. Using this sensing system, we successfully monitored the strain responses of the reconstructed AT in an in vivo porcine model. This facilitated the postoperative assessment of mechanical stiffness variations through a well-established analytical model during the healing period.

Abstract PO5-11-03: Associations among BMI and patient-reported body image dissatisfaction after breast reconstruction

Abstract INTRODUCTION Breast reconstruction surgery helps women restore their physical appearance and contributes to overall well-being. We assessed body image concerns in the context of breast reconstruction using patient-reported outcome measures: Body Image Scale (BIS), Brief Symptom Inventory (BSI), Appearance Schemas Inventory (ASI-R), and BREAST-Q. Since obesity is known to be associated with body image dissatisfaction1, body size may influence a patient’s adjustment to bodily changes arising from breast cancer and its treatment. Thus, we investigated the associations among BMI and patient-reported body image dissatisfaction after immediate autologous breast reconstruction. MATERIAL AND METHODS Patients undergoing breast reconstruction surgery were enrolled in an IRB approved study from 2011 to 2014 at The University of Texas MD Anderson Cancer Center. Participants (N=44) included patients who underwent immediate autologous (DIEP/TRAM) reconstruction and completed the BIS, BSI, ASI-R, and BREAST-Q, both preoperatively and postoperatively at 12+ months. Descriptive statistics including means, standard deviations, and medians were used to summarize continuous variables, while frequencies and percentages were used to summarize the categorical clinical and demographic characteristics. Univariate analyses were conducted to identify potential factors among preoperative variables for subsequent multivariable regression analysis: age, race, ethnicity, BMI, laterality, BIS, BSI, ASI-R, BREAST-Q psychosocial wellbeing score (PWBS), and BREAST-Q satisfaction with breast score (SWBS). Factors with a t test p-value≤0.2 were considered potential predictive variables for the postoperative dependent variables BIS, BREAST-Q PWBS, and BREAST-Q SWBS. Multivariable linear regression models were used to assess the relationship between the dependent and the selected predictive variables. A multivariable linear regression model was fitted using stepwise selection procedure, and the model with the highest adjusted R-squared value and the lowest Akaike information criterion (AIC) was chosen. All tests were two-sided with p-value< 0.05 considered statistically significant, and for each significant predictor, we report the unstandardized coefficient β. Analyses were performed using SPSS 29.0.0 and SAS 9.4. RESULTS Results from the selected models are summarized in Table 1. Age and BMI were significant predictors for postoperative BIS score. Older patients and those with BMI categorized as overweight and obese tend to feel less dissatisfied with their body image after immediate autologous breast reconstruction compared to patients with healthy BMI. Preoperative BSI anxiety was identified as significant predictor for postoperative BREAST-Q PWBS, i.e., patients with higher preoperative anxiety scores tend to have lower postoperative BREAST-Q PWBS. Preoperative BSI anxiety and laterality were significant predictors for postoperative BREAST-Q SWBS. Patients with higher preoperative anxiety scores tend to be less satisfied with their breasts after immediate autologous reconstruction and patients who underwent unilateral reconstruction tend to be less satisfied with their breasts postoperatively compared to patients with bilateral reconstruction. CONCLUSION Women with higher BMI may experience improved body image after undergoing immediate autologous breast reconstruction, as compared to women with healthy BMI. The use of BIS may provide more insight to plastic surgeons compared to relying solely on the body image correlates provided by the BREAST-Q. Moreover, body image counseling can be beneficial for individuals across all BMI categories, including those with healthy BMI. REFERENCES 1.

Abstract PO4-27-02: Pandemic Shifts: How did elective breast cancer care change?

Abstract Introduction: As the COVID-19 pandemic began, concerns arose that timely utilization of elective breast cancer care would decrease due to state moratoriums, travel restrictions, or fear, resulting in poorer long-term outcomes. Advances in telemedicine provided a new avenue for care; however, rapid implementation brought concerns about variable uptake and disparities. To support longitudinal clinical and epidemiological studies, this analysis described elective breast cancer care utilization during the first year of the pandemic, including patient, hospital, and geographic barriers and facilitators. Methods: The Multidisciplinary Breast Reconstruction Research Program team reviewed all breast cancer surgeries and procedures at The University of Texas MD Anderson Cancer Center during the pre-pandemic (March 1, 2019 to February 29, 2020) and pandemic (March 1, 2020 to February 28, 2021) periods. The team identified procedures that were deemed elective or preference-sensitive, and summarized the timeline of pandemic milestones and changes, including the implementation of telemedicine appointments. A data analyst summarized the distributions of completed, canceled, rescheduled, and never completed procedures. T tests and analyses of variance tested differences between the pre-pandemic and pandemic year. Generalized linear models assessed patient, hospital, and geographic factors that correlated with successful access to, and completion of, procedures. Two focus groups reviewed data and informed the interpretation of results. Results: During the first pandemic year, 30 breast care procedures were identified that were postponed during March-April, July-August, and December-January. Surprisingly, no decrease in overall utilization of elective care procedures was observed; in fact, 19% more elective breast cancer care surgeries and procedures were scheduled (4752 pre-pandemic vs 4003 pandemic) in 13% more episodes of care (2723 pre-pandemic vs 2415 pandemic). As expected, rescheduling of procedures increased 98% (from 14% pre-pandemic to 27% pandemic); however, the majority of procedures were able to be completed by the end of the year (72% pre-pandemic, 73% pandemic). Telemedicine did not significantly mediate successful completion, as the majority of procedures were prophylactic or reconstructive surgeries. However, extended hours (p = 0.03) and proximity to the hospital facilitated access and successful completion of care (p< 0.01). The most common procedures that were not able to be performed within the first year of the pandemic were autologous breast reconstruction, revision, and mastopexy. Notably, patients reported slightly improved rates of anxiety and depression during the initial pandemic year (11% vs 14%, p = 0.04), possibly due to relative privation or comparison bias. Clinicians and patients/survivors noted several “lessons learned” that may inform access and preference-sensitive care delivery. Conclusions: Despite three periods of state-mandated discontinuation of elective care procedures, the majority of patients were able to access and successfully complete elective breast cancer care during the first year of the COVID-19 pandemic. Future studies and initiatives may use this information to explore innovations in care delivery and short- and long-term effects on health outcomes.

Abstract PO1-09-05: Reversing Rural Disparity Through Increased Access to Breast Care Using Model of Academic-Community Collaboration

Abstract Background: Rural disparity in Breast Cancer (BC) often relates to poor geographic access. We are small county in rural North Carolina with historically poor outcomes, including more advanced stages of BC at presentation, higher mastectomy rates, and higher BC-specific mortality rates than elsewhere. Beginning in 2002 we increased access to care by construction of a 19-bed Critical Access Hospital. With a higher median age population (10 years older), and cancer as the number one cause of death (30% of all deaths), we began to increase access to services with focus on cancer. Two decades later, we still do not provide all aspects of care locally, but through a model of collaboration we have increased access to all aspects of cancer care. Breast Cancer is the most common, and this report details the reversal in disparity seen rurally based on our model of collaboration with both a regional community cancer program and academic cancer program. Methods: We partnered with academic and community cancer centers in nearby counties to increase access to imaging, cancer specialists, radiation therapy and chemotherapy services, and support services for breast care. When we could not provide these services locally, we helped navigate patients to these other facilities to improve access. We invited dedicated breast surgeon from community cancer program to attend clinic weekly in our area. We created virtual breast-specific tumor boards to discuss 100% of cases prospectively, with improved access to pathologists, geneticists, fellowship-trained imaging specialists, breast surgeons and other multi-disciplinary care members (reconstructive surgery, PT/OT, integrative medicine, GYN). We became cancer accredited with both COC and NAPBC. We compare metrics pre/post-improvements. Results: Baseline: 1. Mortality rates: (2002-2006) 5-year BC mortality rates in our region averaged 32.3/100,000 population which was in the top quartile for the state, 30% higher than the state average. 2. Stages at presentation: 47% of BC stages were early (stages 0/1) in our service region compared to 62% elsewhere (NCDB data). Stage IV represented 6% in our region versus 4% elsewhere. 2500 mammograms/year at hospital at baseline. 3. Surgery/Radiation Therapy: Mastectomy rates averaged >50% in region, with correspondingly lower breast conserving rates than elsewhere due to lack of access to breast surgeons and radiation therapy services locally. Closest RT facility 80 miles. 4. Distances to high quality breast care averaged 150 miles. Closest Academic/Community Cancer Program 2-hour drive (one way). Post Collaboration: 1. Mortality rates: (2015-2019), 5-year BC mortality rates in our region averaged 16.3/100,000 population which is in the lowest quartile, 20% lower than the state average. 2. Stages at presentation: 74% of BC stages are early (stages 0/I) in our region versus 68% elsewhere. Stage IV now below parity with 3% locally versus 4% nationally. More than 5100 mammograms/year done currently at local hospital. 3. Surgery/Radiation Therapy: Mastectomy rates average 21%, with partial mastectomy rates of 79% in our area versus 70% elsewhere (NAPBC data) with RT services available locally. 4. Distances to quality breast care average 20 miles, and we are nationally accredited program in breast care as a critical access hospital. Analytic case load is now triple baseline numbers. Conclusion: We reversed the trend in rural disparity in breast cancer outcomes through model of collaboration. We increased screening rates locally, doubling the number of screening/diagnostic exams, increased the percentage of early stage at diagnosis, halved our mastectomy rates, and reduced BC-specific mortality 50% relative to baseline (and now 20% lower than state). We are now at parity with most BC-specific quality metrics reflecting a huge shift in rural disparity, which could only be achieved rurally through collaboration. Reversing Rural Disparity Through Increased Access to Breast Care Using Model of Academic-Community Collaboration This table depicts the changes in our region over time, which have brought us to parity with Breast Care nationally.

Abstract PO5-19-09: Trial in progress: A prospective randomized, controlled study to evaluate device efficacy for cutting and/or coagulation of tissue during mastectomy procedures

Abstract Background/Purpose: The ConMed HelixAR Electrosurgical Generator with Argon Beam Coagulation Technology (CHEST) trial aims to focus on patients undergoing mastectomy, either unilateral or bilateral, with immediate breast reconstruction including breast implants, tissue expander placement, or autologous flap. The study design follows the standard of care procedure with device efficacy being measured between two devices regularly used in the operative setting: the HelixAR Electrosurgical Generator (HEG) and the Conventional Electrosurgical Coagulation (CEC) systems. The need for safe alternative surgical tools is increasing as the number of women needing surgical treatment increases. Allowing for the test and comparison of these standardized devices gives an extent to the advantages of using one over the other. To evaluate the device effectiveness between the HelixAR Electrosurgical Generator and Conventional Electrosurgical Coagulation systems for cutting and/or coagulation of tissue during mastectomy and reconstruction surgery, we report the implementation in a randomized clinical trial. The study is powered to show superiority of the HEG to the CEC as it relates to the primary objective of time from post-mastectomy to hemostasis. The HEG is designed to deliver argon gas and high frequency electrical current compared to the CEC delivering high frequency electrical current only. The primary efficacy measure is the time it takes from post-mastectomy to hemostasis with the secondary effectiveness endpoints being infection, drain duration, total drain output, blood loss and device related adverse events. The study hypothesizes that the time for post-mastectomy hemostasis is significantly less for the HEG than the CEC. Additional hypotheses include overall less device related adverse events, lower blood loss, and reduced operative time in favor of the HEG. Methods: This is a prospective 1:1 randomized controlled study of the HEG versus the CEC for patients undergoing a mastectomy with reconstruction procedure. 82 patients will be enrolled and distributed in two arms of 41 patients with a primary objective to assess the device efficacy for cutting and coagulation. The subject population includes patients with breast cancer or high risk from genetic mutations and/or family history. Exclusion factors include known history of bleeding diathesis or coagulopathy, advanced refusal of blood transfusion, active systemic or cutaneous infection or inflammation. The enrolled patients will be followed for 2 months post-operatively. Results: The study is open with 53/82 (65%) patients enrolled at the time of the abstract submission. Of those, 26 subjects were randomized to the CEC and 27 to the HEG. 27 subjects have experienced an adverse or serious adverse event including bruising, infections, and wound dehiscence, none determined to be related to the device use. For the study, analysis will focus on the primary endpoint comparing post–mastectomy procedure time to hemostasis between the two devices. Conclusion: The CHEST trial demonstrates the feasibility of conducting a randomized controlled trial at a single center in a complex operative setting comparing two surgical modalities. The testing of these surgical devices provides rationale for the implementation of safe and regulated clinical trials. While both devices are FDA approved and regularly used, the standardization of device efficacy is becoming more prevalent as new innovations get introduced into the surgical setting.

Abstract PO3-20-12: A Case Report on the Management of a Patient with Local Breast Cancer, BIA-ALCL and Radiation Induced Metastatic Angiosarcoma: A Multidisciplinary Approach

Abstract A Case Report on the Management of a Patient with Local Breast Cancer, BIA-ALCL and Radiation-Induced Metastatic Angiosarcoma: A Multidisciplinary Approach  Abstract: Breast cancer recurrence presents a complex challenge in clinical practice. We present the case of a 60-year-old female with a history of stage 2A right breast cancer diagnosed on 12/1/2013. The patient underwent bilateral mastectomy and adjuvant chemotherapy, followed by breast reconstruction. The patient subsequently developed asymmetric right breast swelling, which was biopsied and was positive for T lymphocyte markers CD30, CD43, CD45, CD4 and she was diagnosed with anaplastic large cell lymphoma in 12/14/2018, which was thought to be associated with her breast implants. In May 2022, a right chest wall mass was detected, which demonstrated growth and increased vascularity on imaging. A biopsy on 5/5/22 confirmed poorly differentiated carcinoma initially thought to be a secondary intraductal carcinoma of the breast, invading the chest wall by metastasis or direct extension, negative for estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). Further workup confirmed this mass to be angiosarcoma, most likely associated with the patient’s prior radiation therapy. The patient was started on neoadjuvant carboplatin/paclitaxel/pembrolizumab on 6/9/2022, and continued with Doxorubicin/Cyclophosphamide and pembrolizumab, which was completed on 11 November 2022. Imaging studies post-treatment showed a slightly smaller mass in the right mastectomy bed, indicating a partial response to treatment. However, a subsequent PET scan revealed a recurrence of breast cancer in the right chest wall. Considering the patient's history of prior radiation therapy and the inability to administer further radiation, the treatment plan was revised. She underwent reconstructive chest wall surgery on 1/4/2023, with complete resection and negative margins. She started on adjuvant pembrolizumab planned for one year, but the patient presented on 3/3/2023 with the growth of a chest wall mass and bleeding, consistent with progression. Liquid Tempus testing was obtained but negative for an actionable target. Options such as hyperthermia, enrollment to clinical trial, and re-irradiation were discussed, and the patient was restarted on weekly paclitaxel on 3/31/2023 due to a previous response. The patient had further local disease progression on 5/26/2023, and this regimen was stopped. The patient is planning to get Tempus testing on tumor tissue and start the next line palliative regimen with either doxorubicin or gentamicin and repeat re-irradiation if no response to these regimens. This case report highlights the challenges in managing breast cancer therapy-induced adverse conditions with two secondary tumors, both associated with the patient’s prior therapy. The importance of a multidisciplinary approach, including medical oncology, surgical oncology, radiation oncology, and sarcoma specialists, is emphasized. The use of molecular testing and consideration of clinical trials may provide additional treatment options. Further research and clinical trials are warranted to optimize the management of recurrent breast cancer with transformation to rare histological subtypes such as angiosarcoma.

Abstract PO4-22-11: Study to Compare the Safety of Immediate One-stage IBBR With Expander-Implant Two-stage IBBR Augmented With TiLoop® Bra(COSTA)

Abstract Background: The use of TiLOOP@ Bra in implant-based breast reconstruction (IBBR) becomes standard of care in mainland China. But evidence is limited about complication of one-stage and two-stage IBBR using TiLOOP@ Bra. A prospective randomized trial was conducted to compare the safety of immediate IBBR with that of immediate-delayed IBBR, both with TiLOOP@ Bra. Methods: We did an open label, randomized, controlled trial in eleven hospitals in the mainland China. Inclusion criteria: Women aged above 18 with cT0-T2N0M0 breast carcinoma which requires to undergo nipple or skin-sparing mastectomy (NSM or SSM) and immediate IBBR. Randomization was done electronically, stratified per center and in blocks of four of six to achieve approximately balanced groups of patients assigned to undergo one-stage or two-stage IBBR. Both procedures were undergone pectoralis major and TiLOOP@ Bra to build pockets. The primary endpoint of the present study was the incidence of postoperative complications (within 90 days after surgery), while the secondary endpoints were the quality of life at 18 months after surgery, satisfaction with breast appearance, aesthetic scores of reconstructed breasts, type of reoperation and TiLOOP@ Bra angiopathological assessment. This study is registered at clinicaltrials.gov, number NCT03589924. Findings: Between June 2018 and May 2022, a total of 418 eligible patients were randomly assigned to either two-stage implant reconstruction (n=194) group or immediate one-stage implant reconstruction (n=224) group. In terms of surgical procedures, NSM was more commonly (72.7%) chosen, with the two-stage implant reconstruction group having a lower proportion compared to the immediate one-stage implant reconstruction (66.3% vs. 78.3%; p=0.010). At 3 months after breast reconstruction surgery, the incidence of complications was lower in the two-stage implant reconstruction group than that in the immediate one-stage implant reconstruction group, with significant difference of 14.5% vs 23%; p=0.038. The incidence of nipple or areola necrosis was lower in the two-stage implant reconstruction group compared to the immediate one-stage implant reconstruction group, with statistically significant difference of 9.8% vs 17.1%; p=0.048. The implant loss rate was only 0.7%. It was discovered that the incidence of severe complications was lower in the two-stage implant reconstruction group than in the immediate one-stage implant reconstruction group (2.6% vs. 3.7%), and the difference was not statistically significant. Patients who experienced complications had a higher proportion of chemotherapy (69.2% vs. 38.9%; p< 0.001), endocrine therapy (74.4% vs. 53.9%; p=0.002), and targeted therapy (24.4% vs. 9.6%; p=0.001), and the differences were statistically significant. In terms of surgical procedures, 67 (85.9%) patients who experienced complications underwent NSM, while the proportion of NSM in patients who did not experience complications was lower at 69.6%, which were 231 patients, and the difference was statistically significant (p=0.011). In addition, the complication incidence of patients who received implants sizes of 300-400ml was higher than that of the group that did not (32.1% vs. 17.8%; p=0.012). Conclusion: Both one-stage and two-stage TiLOOP@-assisted IBBR demonstrated perioperative safety. The complication rate within three month of two-stage is lower than one-stage. The implant loss rate was only 0.7% perioperatively. Our results suggest that use of TiLOOP@ Bra be considered carefully for one-stage NSM with IBBR but can be considered for SSM patients.

Perioperative Hypothermia in Elderly Patients During Pelvic Floor Reconstruction Surgery: An Observational Study.

The potential predictors of pelvic floor reconstruction surgery hypothermia remain unclear. This prospective cohort study was aimed at identifying these predictors and evaluating the outcomes associated with perioperative hypothermia. Elderly patients undergoing pelvic floor reconstruction surgery were consecutively enrolled from April 2023 to September 2023. Perioperative temperature was measured at preoperative (T1), every 15min after the start of anesthesia (T2), and 15min postoperative (T3) using a temperature probe. Perioperative hypothermia was defined as a core temperature below 36°C at any point during the procedure. Multivariate logistic regression analysis was conducted to determine factors associated with perioperative hypothermia. A total of 229 patients were included in the study, with 50.7% experiencing hypothermia. Multivariate analysis revealed that the surgical method involving pelvic floor combined with laparoscopy, preoperative temperature < 36.5°C, anesthesia duration ≥ 120min, and the high levels of anxiety were significantly associated with perioperative hypothermia. The predictive value of the multivariate model was 0.767 (95% CI, 0.706 to 0.828). This observational prospective study identified several predictive factors for perioperative hypothermia in elderly patients during pelvic floor reconstruction surgery. Strategies aimed at preventing perioperative hypothermia should target these factors. Further studies are required to assess the effectiveness of these strategies, specifically in elderly patients undergoing pelvic floor reconstruction surgery.

Abstract PO3-23-05: Capsular contracture after post-mastectomy radiotherapy in the patients undergoing implant-based breast reconstruction: impact of implant positioning and two-stage surgery

Abstract Background Capsular contracture is a significant concern in patients undergoing post-mastectomy radiotherapy (PMRT) following implant-based breast reconstruction. It negatively impacts cosmetic outcomes and can have a profound effect on the individual's quality of life. Our study aimed to explore whether the degree of capsular contracture varies based on the placement of the inserted implant and the type of operation (one- or two-staged). Patients and Methods This retrospective study was conducted at a single center, Ganganm Severance Hospital, Yonsei University College of Medicine, Seoul, South Korea. Our study included patients who underwent PMRT following total mastectomy and implant-based breast reconstruction surgery between January 2017 and September 2022. To assess the degree of capsular contracture, we evaluated the presence of capsular contracture, particularly severe capsular contracture classified as Baker grade 3 or higher, as well as implant migration. The implants were placed either in the pre-or sub-pectoral position, and the surgical approach employed was either direct-to-implant (DTI) or two-staged operation. Results A total of 195 patients were included in the study, with 83 (42.6%) patients in the pre-pectoral group and 112 (57.4%) patients in the sub-pectoral group. In addition, 116 underwent a two-stage operation, while 79 underwent DTI surgery. There was a significant difference in the occurrence of capsular contracture based on the implant placement, with 16 patients (19.3%) in the pre-pectoral group and 46 patients (41.1%) in the sub-pectoral group experiencing this complication (OR 4.142 [1.973-8.698]). Furthermore, the severity of capsular contracture differed significantly between the two groups, with 5 patients (6.0%) in the pre-pectoral group and 16 patients (14.3%) in the sub-pectoral group affected (OR 3.434 [1.153-10.227]). The incidence of capsular contracture was lower in the two-stage operation group compared to the DTI group (28 [23.9%] vs 34 [38.6%]; OR 3.064 [1.528-6.141]), and the severity of capsular contracture was also reduced (9 [7.7%] vs 12 [14.5%]; OR 2.854 [1.092-7.455]). There were no significant differences in other complications such as seroma and infection. In addition, sub-pectoral placement was identified as a significant risk factor for implant upward migration (OR 2.531 [95% CI, 1.263-5.071]). Conclusions Our findings suggest that pre-pectoral reconstruction and the two-stage operation are beneficial for patients who may undergo PMRT based on their initial nodal stage. These approaches can help reduce the incidence of capsular contracture and abnormal implant migration following radiation, leading to improved aesthetic outcomes and greater patient satisfaction.

Publications in Plastic Surgery and Reconstruction: A Review from a Developing Country, Sudan.

Plastic and reconstructive surgery services need to be improved in developing African countries. Research and article publications from those countries are limited. This review was conducted to identify published articles from Sudan in the area of plastic and reconstructive surgery. This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. The Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines were used for the preparation of this systematic review. A comprehensive systematic search was performed using PubMed, ScienceDirect, and Web of Science databases. Articles published in Sudan, specifically in the area of plastic and reconstructive surgery, and written in English were included in this review. The total number of articles that fulfilled the inclusion criteria was 23. The articles were written from 1969 to 2023. Only two articles were published in the 20th century. The most common study type was a retrospective study of eight articles, and the most common study area was Khartoum Teaching Hospital. Regarding the publishing journals, the number of subscription journals was six (30%), whereas open access was 17 (70%). This review demonstrates the lack of articles published on plastic surgery in Sudan. Further investigation is needed to determine the challenges and problems associated with possible clarifications.

Interdisciplinary plastic and reconstructive surgery of head and neck squamous cell carcinomas.

Squamous cell carcinomas are the most common malignancies in the oral cavity, pharynx, and larynx. Even in the age of the most modern drug treatment methods, radical resection of these tumors is and currently remains the therapeutic gold standard. The loss of anatomical structures associated with surgery inevitably increases the functional deficits caused by the tumor itself. In this context, the extent of functional deficits is largely determined by the extent of resection. Complete organ resections, such as glossectomy, complete palate resection, laryngectomy, or transverse pharyngo-laryngectomy, lead to severe functional deficits, such as swallowing disturbances with life-threatening aspiration and articulation disorders up to the inability to speak. With the help of plastic reconstructive surgery, the lost tissue can be replaced and the specific functions of the upper aerodigestive tract can be preserved or restored.In recent decades, reconstructive surgical procedures have developed enormously in the treatment of malignant tumors of the head and neck. In order to make optimal use of them, a comprehensive, interdisciplinary therapy concept is a prerequisite for positive oncological and functional outcome. In addition to general medical and social parameters, surgical parameters play a crucial role in the choice of the reconstruction method. The extent to which the surgical measures must be interdisciplinary depends on the localization of the defects in the head and neck region and on the type of replacement tissue required. Here, the expertise of plastic surgery, oral and maxillofacial surgery, and abdominal surgery comes into play in particular. The use of different tissues, the combination of different grafts and flaps, or the preforming of donor regions allow reconstructions far beyond the level of simply restoring surface integrity. The functional results and thus the quality of life of patients after surgical therapy of extensive tumors of the mentioned localizations depend decisively on the type of reconstruction. Therefore, in the following review, special emphasis 1 be placed on the choice of reconstruction method and reconstruction technique for tissue loss after resections of HNSCC.

Case Report: False aneurysm as a late unusual complication of the aortofemoral bypass graft in a patient with critical leg ischemic symptoms: interesting case

Aortofemoral bypass surgery is a common procedure for treating aortoiliac occlusive disease, also known as Leriche syndrome, which can cause lower extremity ischemic symptoms. Diagnostic imaging techniques play a crucial role in managing pseudoaneurysms (PSAs), with Duplex ultrasound and Computed Tomography-angiography (CTA) being effective tools for early diagnosis. Pseudoaneurysms (PSAs) present as pulsating masses with various symptoms, and prompt intervention is essential to avoid complications. A case report is presented involving an 82-year-old male who underwent aorto-bifemoral bypass surgery and later developed a pseudoaneurysm (PSA) of the left branch. Surgical treatment involved the removal of the pseudoaneurysm (PSA) and graft replacement. Other cases from the literature are also described, emphasizing the rarity and potential severity of non-anastomotic pseudoaneurysms (PSAs) in reconstructive vascular surgery. Periodic screening of patients who undergo reconstructive vascular surgery is crucial to detect pseudoaneurysms (PSAs) early and prevent complications. Asymptomatic pseudoaneurysms (PSAs) can grow significantly and become life-threatening if not identified in a timely manner. Regular post-operative imaging, such as annual Computed Tomography-angiography (CTA) and/or Duplex ultrasound, is recommended to ensure early diagnosis and appropriate management of complications.

3D Lipogluing: Preliminary Results of a Novel Technique for Direct Three-dimensional Fat Grafting in Breast Reconstruction Surgery.

Lipofilling has emerged as an effective technique in breast reconstruction for enhancing aesthetic outcomes and addressing residual deformities. Traditionally, fat grafting has been performed as a secondary step in implant-based breast reconstruction during the replacement of the expander with a breast implant or as a revisional procedure. Our study investigates the technical feasibility and presents preliminary results of a new promising technique for delivering fat grafting in a three-dimensional (3D) shape, directly during mastectomy with immediate breast reconstruction or in delayed breast reconstructive procedures. Our new 3D lipogluing technique involves securing the fat tissue in a 3D manner using fibrin glue. This method enhances the coverage of soft tissues and provides improved volume and shape supplementation. In selected cases between December 2015 and September 2023, we treated 24 patients using the 3D lipogluing technique and five patients using 3D lipocubing (without use of fibrin glue).The patient cohort consisted of different indications for breast reconstructions: direct-to-implant, expander-based breast reconstruction, and "conservative" surgery. Preliminary findings suggest the technique is a safe and effective approach that can enhance the soft-tissue envelope of reconstructed breasts by acting as an autologous scaffold, owing to its regenerative properties. This technique not only improves the overall aesthetic outcome but also has the potential to reduce implant-related complications. Furthermore, ongoing studies are investigating methods to optimize the results and explore the potential application of 3D lipogluing and 3D lipocubing in breast-conserving oncoplastic surgery, cosmetic breast surgery, and other areas of plastic reconstructive and aesthetic surgery.
