Laparoscopically harvested omental flap for immediate breast reconstruction: a retrospective single-center study of 300 cases.

BACKGROUND: The laparoscopically harvested omental flap (LHOF) has been used in partial or total breast reconstruction, but most studies on LHOF were case reports or small case series. However, the clinical feasibility and oncological safety of LHOF in oncoplastic breast surgery remains controversial. This study reported our experience applying LHOF for immediate breast reconstruction. METHODS: Between June 2018 and March 2022, 300 patients underwent oncoplastic breast surgery using LHOF at our institution. Their clinicopathological data, complications, cosmetic outcomes, and oncologic outcomes were evaluated. RESULTS: All patients underwent total breast reconstruction using LHOF after nipple-sparing mastectomy. The median operation time was 230 min (ranging from 155 to 375 min). The median operation time for harvesting the omental flap was 55 min (ranging from 40 to 105 min). The success rate of the laparoscopically harvested pedicled omental flap was over 99.0%. Median blood loss was 70 ml, ranging from 40 to 150 ml. The volume of the flap was insufficient in 102 patients (34.0%). The overall complication rate was 12.3%. Subcutaneous fluid in the breast area (7%) was the most common reconstruction-associated complication, but most cases were relieved spontaneously. The incidence rate of omental flap necrosis was 3.3%. LHOF-associated complications occurred in two cases, including one case of incisional hernia and one case of vascular injury. Cosmetic outcomes were satisfactory in 95.1% of patients on a four-point scale by three-panel assessment and 97.2% using the BCCT.core software. Two local and one systemic recurrence were observed during a median follow-up period of 32 months. CONCLUSIONS: The LHOF for immediate breast reconstruction is a safe and feasible method that involves minimal donor-site morbidity, satisfactory cosmetic outcomes, and promising oncologic safety.

Minimizing Nipple-Areolar Complex Complications in Prepectoral Breast Reconstruction After Nipple-Sparing Mastectomy.

PURPOSE: Nipple-areolar complex (NAC) viability remains a significant concern following prepectoral tissue expander (TE) reconstruction after nipple-sparing mastectomy (NSM). This study assesses the impact of intraoperative TE fill on NAC necrosis and identifies strategies for mitigating this risk. METHODS: A chart review of all consecutive, prepectoral TEs placed immediately after NSM was performed between March 2017 and December 2022 at a single center. Demographics, mastectomy weight, intraoperative TE fill, and complications were extracted for all patients. Partial NAC necrosis was defined as any thickness of skin loss including part of the NAC, whereas total NAC necrosis was defined as full-thickness skin loss involving the entirety of the NAC. P < 0.05 was considered statistically significant. RESULTS: Forty-six patients (83 breasts) with an average follow-up of 22 months were included. Women were on average 46 years old, nonsmoker (98%), and nondiabetic (100%) and had a body mass index of 23 kg/m2. All reconstructions were performed immediately following prophylactic mastectomies in 49% and therapeutic mastectomies in 51% of cases. Three breasts (4%) were radiated, and 15 patients (33%) received chemotherapy. Mean mastectomy weight was 346 ± 274 g, median intraoperative TE fill was 150 ± 225 mL, and median final TE fill was 350 ± 170 mL. Partial NAC necrosis occurred in 7 breasts (8%), and there were zero instances of complete NAC necrosis. On univariate analysis, partial NAC necrosis was not associated with any patient demographic or operative characteristics, including intraoperative TE fill. In multivariable models controlling for age, body mass index, mastectomy weight, prior breast surgery, and intraoperative TE fill, partial NAC necrosis was associated with lower body mass index (odds ratio, 0.53; confidence interval [CI], 0.29-0.98; P < 0.05) and higher mastectomy weight (odds ratio, 1.1; CI, 1.01-1.20; P < 0.05). Prior breast surgery approached significance, as those breasts had a 19.4 times higher odds of partial NAC necrosis (95% CI, 0.88-427.6; P = 0.06). CONCLUSIONS: Nipple-areolar complex necrosis following prepectoral TE reconstruction is a rare but serious complication. In this study of 83 breasts, 7 (8%) developed partial NAC necrosis, and all but one were able to be salvaged.

Impact of Comorbidities on Sensory Return After Breast Reconstruction.

PURPOSE: Breast anesthesia after mastectomy and reconstruction has been an ongoing concern with few improvements made in recent years. At present, there is a lack of studies evaluating the impact of comorbidities on sensation restoration. Identifying risk factors (RF) will be helpful with preoperative counseling. METHODS: This was a prospective study on patients who underwent mastectomy and immediate implant-based or neurotized deep inferior epigastric perforator (DIEP) flap-based reconstruction. Neurosensory testing was performed at predefined time points using a pressure specified device. Patients were stratified based on reconstruction type and comorbidities, including obesity (≥30 kg/m2), age (>55 years), hypertension, alcohol use, and smoking status. Sensory comparisons among the comorbidity groups were conducted using unpaired 2-sample t tests. RESULTS: A total of 239 patients were included in this study with 109 patients in the implant cohort and 131 patients in the DIEP cohort. One patient underwent bilateral reconstruction using both reconstructive modalities. Preoperatively, age older than 55 years was identified as an RF for reduced breast sensation in the implant cohort (difference in threshold, 10.7 g/mm2), whereas obesity was identified as an RF in the DIEP cohort (difference in threshold, 8 g/mm2). During the first 2 years postreconstruction, age older than 55 years and tobacco use history were found to be negatively correlated with breast sensation for both cohorts. With DIEP reconstruction specifically, obesity was identified as an additional RF during the early postoperative period. Of note, none of the comorbidities were found to be long-term RFs for reduced breast sensitivity. All breast sensation levels returned to comparable levels across all comorbidities by 4 years postreconstruction. CONCLUSIONS: Currently, various comorbidities have been recognized as RFs for several postoperative complications including extended postoperative stay, necrosis, infection, and reoperation. However, our findings suggest that, although age, smoking history, and obesity showed transient associations with reduced breast sensation during the initial years postreconstruction, they play no role in the long-term potential of sensory nerve regeneration.

Obesity Portends Increasing Rates of Superficial Surgical Site Infection Following Pediatric Reduction Mammoplasty: A National Surgical Database Analysis.

INTRODUCTION: Pediatric reduction mammoplasty has become increasingly common due to the obesity epidemic. While obesity remains the leading cause of macromastia leading to surgery, it may also be a risk factor for postoperative complications. This study examines the safety of pediatric reduction mammoplasty and the risk of obesity for complications following this procedure. METHODS: The American College of Surgeons National Surgical Quality Improvement Program Pediatrics was queried to obtain all reduction mammoplasty cases from 2012 to 2020. Univariate and multivariate logistic regression analyses controlling for confounders were carried out to assess the relationship between body mass index (BMI) and rates of complication. RESULTS: One thousand five hundred eighty-nine patients with the primary Current Procedural Terminology code 19318 were included in the final analysis. The mean age was 16.6 (SD, 1.1) years, and the mean BMI was 30.5 (SD, 6.2) lb/in2. Notably, 49% of the patients were obese, and 31% were overweight, while only 0.4% were underweight. Forty-three patients (2.7%) sustained a superficial surgical site infection (SSI) postoperatively. Other complications were less prevalent, including deep SSI (4 patients, 0.3%), dehiscence (11, 0.7%), reoperation (21, 1%), and readmission (26, 1.6%).Independent variables analyzed included age, sex, BMI, diabetes mellitus, American Society of Anesthesiologists (ASA) class, and operative time, of which only BMI and ASA class were found to be significantly associated with SSI on univariate analysis. On multivariate logistic regression while controlling for ASA class and the false discovery rate, there was a strong association between increasing rates of superficial SSI and increasing BMI (unit odds ratio, 1.05; 95% confidence interval, [1.01, 1.09]; P = 0.02). The OR indicates that for each 1-unit increase in BMI, the odds of SSI increase by 5%. CONCLUSIONS: Complications following pediatric reduction mammoplasty are uncommon, demonstrating the safety of this procedure. High BMI was found to have a significantly higher risk for superficial SSI. Increased caution and infection prophylaxis should be taken when performing this operation on obese patients.

Level-2 Oncoplastic Surgical Techniques for Breast Cancer: A Preliminary Vietnamese Report.

Background: Breast cancer is the most common malignancy and remains the first cause of death related to cancer among Vietnamese women, with an incidence of 21,555 cases in 2020. Most breast cancer patients present with invasive disease and relatively large tumor sizes. While oncoplastic surgery (OPS) are commonly applied in Western countries, data on Asian population remains relatively limited. Objective: This study aims to assess the outcomes of level-2 oncoplastic techniques in breast-conserving surgeries at the Vietnam National Cancer Hospital. Methods: From January 2017 to June 2021, a cohort of 257 breast cancer patients who underwent breast-conserving surgery with OPS techniques were examined. Surgical complications, cosmetic outcome, recurrence and survival rates were assessed. Results: The mean age was 47.6±9.4 years, most patients had breast cup sizes B and C. The mean tumor size upon pathological examination was 2.00 ± 0.74 cm. Only 7 cases required reoperation, resulting in a mastectomy rate of 1.17%. The overall complication rate was low at 11.46%, with 9 cases (3.56%) experiencing delayed complications. Cosmetic results were rated as "excellent" in 20.6% and "good" in 60.5%, with a statistically significant difference. The rates of local recurrence, regional recurrence, and distant metastasis at five years were 2.78%, 1.19%, and 2.36%, respectively. Conclusion: The level 2 oncoplastic techniques had low complication rates, favorable oncological outcomes, and cosmetically satisfying results.

Development of Opioid Use Disorder After Breast Reconstruction: Effects of Nicotine Exposure.

INTRODUCTION: After undergoing breast reconstructive surgery, patients are typically prescribed opioids. Smoking tobacco increases rate of opioid metabolism and is associated with development of opioid use disorder (OUD). The aim of this study was to determine whether patients who smoke have an increased risk of OUD after breast reconstructive surgery. Given that OUD is a known risk factor for injection drug use and intravenous drug use increases risk of acquiring blood-borne diseases including human immunodeficiency virus (HIV) and hepatitis, the secondary aim was to determine if these patients are also at increased risk of acquiring these communicable diseases associated with OUD. METHODS: A retrospective analysis was conducted using TriNetX, a multi-institutional deidentified database. Individuals included underwent a breast reconstructive surgery and received postoperative opioid treatment. The exposed group included patients who smoke. The control group did not smoke. Risk of developing OUD, hepatitis B virus (HBV), hepatitis C virus (HCV), and HIV from 12 to 36 months after surgery was compared between groups. Patients with preexisting OUD or associated diseases were excluded. Cohorts were matched to control for confounding factors including age, sex, race, mental health history, and concomitant substance use. RESULTS: There were 8648 patients included in the analysis. After matching, 4324 patients comprised the exposure group, and 4324 patients remained in the control group. Preoperative smoking was significantly associated with increased risk of OUD at 12, 24, and 36 months after breast reconstruction (36 months: odds ratio [OR], 2.722; confidence interval [CI], 2.268-6.375). Smoking was also associated with increased risk of HIV and HCV at all time points after surgery (36 months HIV: OR, 2.614; CI, 1.977-3.458; 36 months HCV: OR, 3.718; CI, 2.268-6.375) and increased risk of HBV beginning at 24 months after surgery (36 months HBV: OR, 2.722; CI, 1.502-4.935). CONCLUSIONS: Individuals who smoke have an increased risk of developing OUD, HIV, HCV, and HBV after breast reconstructive surgery. This risk persists for at least 3 years after surgery. Additional research and clinical interventions focusing on early identification of OUD, prevention efforts, and harm reduction strategies for patients who smoke or have nicotine dependence undergoing breast reconstruction are warranted.

Use of Absorbable Dermal Staples in Bilateral Breast Reduction Surgery: Effects on Operative Times, Surgical Outcomes, and Procedure Charges.

BACKGROUND: Use of the absorbable deep dermal stapler in wound closure has become more common in plastic surgery because of its possible reduction in operative times and subsequent decrease in operative room costs. In this study, we examine the effects of this stapler on operative times and postoperative complications in bilateral reduction mammaplasties. METHODS: A retrospective, observational cohort study was conducted via electronic chart review on patients who underwent bilateral reduction mammaplasties. Patients were stratified by wound closure method. One group was closed with sutures only, and in the other group, deep dermal staples were used during closure of the inframammary fold incision. Incidences of patient comorbidities and postoperative complications were compared. In addition, a financial cost analysis was performed. RESULTS: The final patient cohort included 62 patients. Operative time was reduced by an average of 21.8 minutes when using deep dermal staples during closure, compared with when closing solely with sutures (P = 0.032). When controlling for mass of breast tissue removed and type of pedicle, deep dermal staple closure still predicted a reduction of 26.5 (SE, 9.9) minutes in operative time (P = 0.010). Postoperative complications were not affected by wound closure method (odds ratio, 4.36; 95% confidence interval, 0.91-31.7, P = 0.087). Though not statistically significant, financial charge was decreased with usage of deep dermal staples (P = 0.34). CONCLUSIONS: Use of absorbable deep dermal staples produces a significant decrease in operative time for reduction mammaplasties with no increase in postoperative complication rates.

Multimodality Imaging of Postmastectomy Breast Reconstruction Techniques, Complications, and Tumor Recurrence.

For women undergoing mastectomy, breast reconstruction can be performed by using implants or autologous tissue flaps. Mastectomy options include skin- and nipple-sparing techniques. Implant-based reconstruction can be performed with saline or silicone implants. Various autologous pedicled or free tissue flap reconstruction methods based on different tissue donor sites are available. The aesthetic outcomes of implant- and flap-based reconstructions can be improved with oncoplastic surgery, including autologous fat graft placement and nipple-areolar complex reconstruction. The authors provide an update on recent advances in implant reconstruction techniques and contemporary expanded options for autologous tissue flap reconstruction as it relates to imaging modalities. As breast cancer screening is not routinely performed in this clinical setting, tumor recurrence after mastectomy and reconstruction is often detected by palpation at physical examination. Most local recurrences occur within the skin and subcutaneous tissue. Diagnostic breast imaging continues to have a critical role in confirmation of disease recurrence. Knowledge of the spectrum of benign and abnormal imaging appearances in the reconstructed breast is important for postoperative evaluation of patients, including recognition of early and late postsurgical complications and breast cancer recurrence. The authors provide an overview of multimodality imaging of the postmastectomy reconstructed breast, as well as an update on screening guidelines and recommendations for this unique patient population. ©RSNA, 2024 Test Your Knowledge questions for this article are available in the supplemental material.

Risk factors for severe complications and salvage management in direct-to-implant immediate breast reconstruction: A retrospective study.

Controversies regarding the risk factors affecting direct-to-implant (DTI) immediate breast reconstruction still exist. This study aimed to evaluate the risk factors for severe complications in DTI breast reconstruction and explore potential salvage management strategies. We conducted a retrospective review of 238 patients (240 breasts) who underwent DTI immediate breast reconstruction between 2011 and 2020. Multivariate logistic regression analyses were used to identify the risk factors predicting severe complications. Seventeen (7.08%) reconstructed breasts experienced severe complications, of which only 5 were successfully salvaged through surgical revision, while the others failed and resulted in implant removal. Multivariate analyses demonstrated that mesh use [odds ratio (OR) = 4.054, 95% confidence interval: 1.376-11.945, P = .011] and post-mastectomy radiotherapy (odds ratio = 4.383, 95% confidence interval 1.142-16.819, P = .031) were independent predictors of severe complications. Mesh use and post-mastectomy radiotherapy for breast reconstruction increase the risk of severe complications. Despite positive surgical treatment, the successful salvage rate was poor.

Effectiveness of SCAR-Q for assessment of incisional SCAR after implant-based reconstruction in breast cancer patients: Can it be a tool for incision selection?

Incisional scarring is a factor of cosmetic appearance evaluated after breast reconstruction, along with the shape, position, and size of the breast. This study aimed to examine the effect of the incision scar location on patient satisfaction after breast reconstruction. Using the Japanese version of the SCAR-Q, we assessed the scar appearance, symptoms and psychosocial effects. Plastic surgeons performed assessments using the Manchester Scar Scale. The patients were divided into two groups: those with scars on the margins of the breast (MB group) and those with scars in the breast area (IB group). The results revealed that patients in the MB group reported significantly higher satisfaction with the scar appearance and psychological impact than those in the IB group. However, assessments using the Manchester Scar Scale did not reveal any significant differences between the two groups. In conclusion, this study underscores the importance of patient-reported outcomes in the evaluation of scar satisfaction after breast reconstruction. Patients tend to prefer and have higher satisfaction with scars along the breast margin, which offers valuable insights into surgical decisions. Further studies with larger and more diverse sample sizes are required for validation.

From Case Reports to Molecular Insight: Examining the Outcomes and Underlying Mechanisms of Squamous Cell Carcinoma in Breast Implant Patients-A Systematic Review.

There is extensive coverage in the existing literature on implant-associated lymphomas like anaplastic large-cell lymphoma, but breast implant-associated squamous cell carcinoma (BIA-SCC) has received limited scholarly attention since its first case in 1992. Thus, this study aims to conduct a qualitative synthesis focused on the underexplored association between breast implants and BIA-SCC. A systematic review was conducted utilizing the PubMed, Web of Science, and Cochrane databases to identify all currently reported cases of BIA-SCC. Additionally, a literature review was performed to identify potential biochemical mechanisms that could lead to BIA-SCC. Studies were vetted for quality using the NIH quality assessment tool. From an initial pool of 246 papers, 11 met the quality criteria for inclusion, examining a total of 14 patients aged between 40 and 81 years. BIA-SCC was found in a diverse range of implants, including those with smooth and textured surfaces, as well as those filled with saline and silicone. The condition notably manifested a proclivity for aggressive clinical progression, as evidenced by a mortality rate approximating 21.4% within a post-diagnostic interval of six months. Our literature review reveals that chronic inflammation, driven by various external factors such as pathogens and implants, can initiate carcinogenesis through epigenetic modifications and immune system alterations. This includes effects from exosomes and macrophage polarization, showcasing potential pathways for the pathogenesis of BIA-SCC. The study highlights the pressing need for further investigation into BIA-SCC, a subject hitherto inadequately addressed in the academic sphere. This necessitates the urgency for early screening and intervention to improve postoperative outcomes. While the review is confined by its reliance on case reports and series, it serves as a valuable reference for future research endeavors.

Selective Capsulotomies and Partial Capsulectomy in Implant-Based Breast Reconstruction Revision Surgery.

Background: Breast cancer with about 2.3 million diagnoses and 685,000 deaths globally is the most frequent malignancy in the female population. Continuous research has led to oncological and reconstructive advances in the management of breast cancer, thus improving outcomes and decreasing patient morbidity. Nowadays, the submuscular expander and prosthesis (E/P) implant-based breast reconstruction (IBR) accounts for 73% of all reconstructions. Despite its widely accepted efficacy, the technique is not free from complications and up to 28% of cases require revision surgery for mechanical complications such as capsular contracture, implant displacement/rotation, and implant rupture. With this study, the authors report their experience in the management of E/P IBR revision surgery through the technique of Selective Capsulotomies (SCs) and Partial Capsulectomy (PC). Methods: A retrospective study was conducted on patients who had previously undergone E/P IBR and presented for revision reconstruction between January 2013 and May 2023 at the Department of Plastic Surgery of the University of Siena, Italy. Reasons for revision included capsular contracture, implant displacement/rotation, and implant rupture. Revision reconstructions involved SC and PC with implant replacement. Fat grafting was also considered. The complication rate was evaluated by analysis of patients' medical records. Patients' satisfaction with the treatment was assessed through a specific questionnaire. Results: 32 patients underwent revision surgeries. No early complication occurred. Recurrence rate was assessed at 19% with average follow-up of 59 months (range: 13-114 months). The average time between revision surgery and recurrence was 3 years (range: 1-6 years). 23 patients answered the questionnaire and were overall satisfied with the treatments (8.29/10). Conclusions: SC possibly associated to PC is a valuable option for E/P IBR revision surgery with minimal complications, reduced surgical trauma, short operating time, and relatively low recurrence risk. In addition, treated patients are overall satisfied with the results over time.

Efficacy of Serratus Posterior Superior Intercostal Plane Block on Postoperative Pain and Total Analgesic Consumption in Patients Undergoing Reduction Mammoplasty Surgery: An Evidence Based Report.

Serratus posterior superior intercostal plane block (SPSIPB) is a novel technique that provides analgesia in shoulder, hemithorax and in the back of the neck. In this study, the efficacy of this block on postoperative pain and quality of recovery is reported in ten consecutive patients who had undergone reduction mammoplasty. Blocks were performed bilaterally with 30 ml 0.25 % bupivacaine for each side, at the end of surgery. Cumulative tramadol consumption and numerical rating scale (NRS) scores during rest (static) and coughing (dynamic) were assessed within the first postoperative 24 hours. Mean total tramadol consumption was 39 ±9.94 mg. NRS scores above 4 were observed in 5 patients in the dynamic NRS assessment at the postoperative 1st hour, while static and dynamic NRS scores were ≤4 at other durations. SPSIPB may play a part in postoperative multimodal analgesia following mammoplasty in the future and may reduce total analgesic consumption. Key Words: Serratus posterior superior intercostal plane block, Reduction mammoplasty, Breast surgery, Postoperative analgesia.

The impact of race and ethnicity in outpatient breast reconstruction decision-making and postoperative outcomes: A propensity score-matched NSQIP analysis.

BACKGROUND: Recent literature has established outpatient breast reconstruction (BR) to be a safe alternative to inpatient BR. However, the impact of race and ethnicity on BR patient decision-making and postsurgical outcomes remains unexplored. This study aims to assess the impact of race and ethnicity on outpatient BR timing and postoperative complication rates. METHODS: The 2013-2020 ACS-NSQIP database was utilized to identify women undergoing outpatient BR. Propensity score-matched analysis was conducted to generate balanced cohorts based on race and ethnicity. t-tests and Fisher's exact tests were used to assess group differences. Logistic regressions were modeled to evaluate differences in complications between groups. RESULTS: A total of 63,526 patients underwent outpatient BR. After propensity score matching, 7664 patients and 3948 patients were included in the race and ethnicity-based analysis, respectively. There were statistically significant differences in the timing of BR patients received across cohorts. NW patients had lower rates of immediate BR (IBR) compared with White patients (47% vs. 53%, p < 0.001), and this also was seen in Hispanic patients (97% vs. 3%, p = 0.018). Subsequently, there were higher rates of delayed BR (DBR) in the NW cohort (55% vs. 45%, p < 0.001) and in the Hispanic cohort (95% vs. 5%, p = 0.018). There were no significant differences in the rates of 30-day postoperative complications across cohorts. CONCLUSIONS: Ultimately, our findings suggest that minority patients are more likely to undergo DBR than nonminority patients. However, there were no differences in 30-day postoperative outcomes across race or ethnicity. Future studies to elucidate patients' decision-making process in choosing optimal BR types and timing are necessary to better understand the impact of the observed differences in patient care.

Limited English Proficiency Is Not Associated With Poor Postoperative Outcomes or Follow-Up Rates in Patients Undergoing Breast Reduction Mammoplasty - A Single Institution Retrospective Cohort Study.

INTRODUCTION: Limited English Proficiency (LEP) status has been associated with worse patient outcomes on a variety of metrics. METHODS: A retrospective review of all bilateral breast reduction mammoplasty patients at our institution between 2015 and 2019 was performed. Data collected include patient demographics, language status, interpreter usage, complications, and follow-up clinic/emergency department visits. Patients were grouped into high and low follow-up cohorts by median follow-up. Bivariate testing and regression modeling were used for analysis. RESULTS: A total of 1023 patients were included. Average age and body mass index (BMI) were 37.7 years and 31.7 kg/m2. All LEP (21%) patients used interpreters. There were 590 individuals in the low follow-up and 433 in the high follow-up group. Those in low follow-up were younger, with lower BMI, and were more likely to use Medicaid. Prevalence of diabetes and postoperative emergency department visits were higher in the high follow-up cohort. There were no significant differences in race/ethnicity, smoking status, and interpreter use between groups. Poisson modeling demonstrated that presence of complications is associated with a 0.435 increase in the number of clinic visits and a 1-y increase in age is associated with a 0.006 increase (P < 0.001). Interpreter use was not significantly associated with postoperative clinic visits. Multivariable regression modeling demonstrated BMI and diabetes to be significantly associated with incidence of any complication (odds ratio: 1.08 & 2.234; P < 0.001 &P = 0.01, respectively). CONCLUSIONS: LEP status was not associated with worse postoperative outcomes or follow-up length in patients undergoing breast reduction mammoplasty. This may be due to interpreter use and effective patient education.

Flying high?-Exploring the effect of red bull on blood pressure after microsurgical breast reconstruction in a randomized controlled trial.

BACKGROUND: A sufficiently high blood pressure (BP) is essential for flap perfusion after microsurgical breast reconstruction. However, postoperative hypotension is common after these procedures. Perioperative volume overload may increase flap-related complications, and postoperative vasopressor use may be limited depending on institutions. Red Bull has been shown to increase BP in several studies. We aimed to evaluate the effect of Red Bull on perfusion-related variables after microsurgical breast reconstruction. METHODS: We conducted a multicenter, prospective, randomized controlled trial. Female patients undergoing unilateral microsurgical breast reconstruction from June 2020 to October 2022 were randomly assigned to the intervention or control groups. The intervention group received 250 ml of Red Bull 2 h after surgery and twice on postoperative day (POD) 1. The control group received 250 ml still water at the respective intervals. BP was measured using a 24-hour monitoring device. Vasopressor use, fluid balance, and flap outcomes were compared. RESULTS: One hundred patients were included in the study. Both groups were comparable concerning age, body mass index, and caffeine consumption. Mean arterial and diastolic BP were significantly higher in the Red Bull group after the second drink in the morning of POD1 (p-value = 0.03 and 0.03, respectively). Vasopressor use was similar, with a tendency for less postoperative etilefrine in the Red Bull group (p-value = 0.08). No flap loss was observed. CONCLUSIONS: We observed increased mean arterial and diastolic BP in the Red Bull group after the second drink. Red Bull may be a useful adjunct after microsurgical breast reconstruction. LEVEL OF EVIDENCE: I, therapeutic.

Updated Trends and Outcomes in Autologous Breast Reconstruction in the United States, 2016-2019.

INTRODUCTION: Autologous breast reconstruction (ABR) has increased in recent decades, although concerns for access remain. As such, our goal is to trend national demographics and operative characteristics of ABR in the United States. METHODS: Using the National Inpatient Sample, 2016-2019, the International Classification of Disease , Tenth Edition codes identified adult female encounters undergoing ABR. Demographics and procedure-related characteristics were recorded. Discharge weights generated national estimates. Statistical analysis included univariate testing and multivariate regression modeling. RESULTS: A total of 52,910 weighted encounters met the criteria (mean age, 51.5 ± 10.0 years). Autologous breast reconstruction utilization increased (Δ = +5%), 2016-2019, primarily driven by a rise in deep inferior epigastric perforator (DIEP) reconstructions (Δ = +28%; incidence rate ratio [IRR], 1.070; P < 0.001), which were predominant throughout the study period (69%). More recent surgery year, bilateral reconstruction, higher income levels, commercial insurance, and care in the South US region increased the odds of DIEP-based ABR ( P ≤ 0.036). Transverse rectus abdominis myocutaneous flaps, bilateral reconstructions, higher comorbidity levels, and experiencing complications increased the length of stay ( P ≤ 0.038). Most ABRs (75%) were privately insured. The rates of immediate reconstructions increased over the study period (from 26% to 46%; IRR, 1.223; P < 0.001), as did the rates of bilateral reconstructions (from 54% to 57%; IRR, 1.026; P = 0.030). The rates of ABRs performed at teaching hospitals remained high (90% to 93%; P = 0.242). CONCLUSIONS: As of 2019, ABR has become more prevalent, with the DIEP flap constituting the most common modality. With the increasing ABR popularity, efforts should be made to ensure geographic and financial accessibility.

Abdominal donor-site complications following autologous breast reconstruction: A multi-institutional multisurgeon study.

BACKGROUND: The deep inferior epigastric perforator (DIEP) free flap is the gold standard procedure for autologous breast reconstruction. Although breast-related complications have been well described, donor-site complications and contributing patient risk factors are poorly understood. METHODS: We examined a multi-institutional, prospectively maintained database of patients undergoing DIEP free flap breast reconstruction between 2015 and 2020. We evaluated patient demographics, operative details, and abdominal donor-site complications. Logistic regression modeling was used to predict donor-site outcomes based on patient characteristics. RESULTS: A total of 661 patients were identified who underwent DIEP free flap breast reconstruction across multiple institutions. Using logistic regression modeling, we found that body mass index (BMI) was an independent risk factor for umbilical complications (odds ratio [OR] 1.11, confidence interval [CI] 1.04-1.18, p = 0.001), seroma (OR 1.07, CI 1.01-1.13, p = 0.003), wound dehiscence (OR 1.10, CI 1.06-1.15, p = 0.001), and surgical site infection (OR 1.10, CI 1.05-1.15, p = 0.001) following DIEP free flap breast reconstruction. Further, immediate reconstruction decreases the risk of abdominal bulge formation (OR 0.22, CI 0.108-0.429, p = 0.001). Perforator selection was not associated with abdominal morbidity in our study population. CONCLUSIONS: Higher BMI is associated with increased abdominal donor-site complications following DIEP free flap breast reconstruction. Efforts to lower preoperative BMI may help decrease donor-site complications.

Isolated and combined breast augmentation in transgender patients: Multi-institutional insights into early outcomes and risk factors.

BACKGROUND: The increasing demand for gender-affirming surgery (GAS) in transgender and gender-diverse healthcare highlights the importance of breast augmentation surgery (BAS) for transfeminine patients. Despite its significance, there is a lack of research on postoperative outcomes of BAS. METHODS: We analyzed the multi-institutional American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) (2008-2021) database to identify female transgender individuals (TGIs) who underwent BAS surgery, both isolated and combined with concurrent GAS procedures. We evaluated 30-day outcomes, including the incidence of mortality, reoperation, readmission as well as surgical and medical complication occurrence. RESULTS: Of 1699 female TGIs, 92% underwent isolated BAS and 7.7% underwent combined BAS. The mean age and body mass index (BMI) were 36 ± 12 years and 27 ± 6.6 kg/m2, respectively. Isolated BAS showed a 2.8% complication rate, while combined BAS had a higher rate with 9.1%. Specifically, all complications occurred in patients undergoing BAS with concurrent genitourinary surgery (n = 85; 14%), whereas no adverse events were recorded after combined BAS and facial feminization (n = 19) or chondrolaryngoplasty (n = 19). In patients seeking combined BAS, advanced age (p = 0.05) and nicotine abuse (p = 0.004) were identified as risk factors predisposing to adverse events, whereas American Society of Anesthesiology class 1 was found to be protective (p = 0.02). CONCLUSIONS: Isolated BAS in TGIs demonstrates a positive safety profile. Combined surgeries, particularly with genitourinary procedures, pose higher risks. Identifying risk factors such as smoking and advanced age is crucial for patient selection and surgical planning. These findings can aid in refining patient eligibility and inform surgical decision-making for BAS.
