A woman in her thirties with dyspnoea two weeks after abdominoplasty. / En kvinne i 30-årene med dyspné to uker etter bukplastikkoperasjon.

Background: While most cases of venous thromboembolism follow a benign course, occasionally the condition may manifest a complex clinical presentation and need a comprehensive diagnostic workup to identify the underlying cause and provide the patient with appropriate treatment. Case presentation: A woman in her late thirties presented to the emergency department with a five-day history of dyspnoea. She had recently undergone liposuction surgery after pregnancy. Upon admission, initial investigations revealed a pulmonary embolism with right heart strain, and she was treated with anticoagulants. The following day, she complained of acute-onset right flank pain without fever or other accompanying symptoms. A CT scan of the abdomen confirmed a right-side renal infarction. Further investigations revealed patent foramen ovale between the right and left atria of the heart, believed to be the source of a right-to-left shunt of arterial emboli. Although the patient had not suffered a clinical stroke, it was decided to close this defect using percutaneous technique. Interpretation: Patent foramen ovale is a common condition in adults, but in most cases it remains asymptomatic. However, patients with patent foramen ovale have an elevated risk of arterial emboli affecting multiple organs. The diagnosis depends on thorough assessment to prevent potentially fatal outcomes.

Minimally invasive lipoabdominoplasty (MILA) tactic.

While diastasis recti (DR) was long neglected by general surgeons, plastic surgeons considered conventional abdominoplasty as the only repair option. However, this scenario has changed recently, either due to a better understanding of the correlation between DR and abdominal wall function and greater risk of recurrence in abdominal hernia repairs, or due to the development of new minimally invasive techniques for repairing DR. One of these surgical procedures consists of the concept of an abdominoplasty, that is, supra-aponeurotic dissection and plication of the DR (with or without abdominal hernia) but performed through three small supra-pubic incisions by laparoscopy or robotic approach. More recently, this procedure has gained new stages. Liposuction and skin retraction technology have been associated with MIS plication of DR, which increases the indications for the technique and potentially improves results. For the first time in the literature, we describe these steps and the synergy between them.

Is There a Direct Effect Between the Plication of the Myoaponeurotic Layer and the Force of Inspiratory and Expiratory Muscles After Abdominoplasty?

OBJECTIVE: Abdominoplasty may generate an increase in the intra-abdominal pressure (IAP) and consequently an alteration in the pulmonary ventilation. The purpose of this study was to evaluate the potential alterations in the maximal static inspiratory pressure (MIP) and maximal static expiratory pressure (MEP) after abdominoplasty. METHODS: Thirty-three female patients, aged between 18 and 60, with type III/B Nahas abdominal deformity that underwent abdominoplasty with plication of the anterior rectus and external oblique aponeurosis were selected. The MIP and MEP were measured using a mouthpiece. This is a simple way to indirectly gauge inspiratory and expiratory muscle strength. Measurements were performed before surgery and on the 2nd, 7th, 15th, and 180th postoperative day. In addition, IAP was measured before abdominoplasty and after the placement of compression garment. The MIP and MEP were compared using analysis of variance, followed by the Bonferroni multiple comparison test pairing the different points in time. Paired Student's t test was used for comparing IAP measurements. Pearson's correlation test was used to compare MIP and MEP variations with IAP variation. Results were considered statistically significant when P ≤ 0.05. RESULTS: A decrease was observed in MEP on the 2nd day, with a return close to normal values on the 15th day. In opposition MIP had a surprisingly increase on the 15th postoperative day (129 cmH2O), normalizing 180 days after the operation. A leap in IAP values was revealed at the end of the surgical procedure. It was not possible to establish a positive correlation between the increase of IAP and the alterations of MIP and MEP. CONCLUSIONS: There is a decrease in maximum expiratory pressure on the very early postoperative day (2nd postoperative day) and an increase in maximum inspiratory pressure on the 15th postoperative day in patients who underwent abdominoplasty. There was no correlation between the IAP and maximum respiratory pressure variations, both inspiratory and expiratory.

Associations between prior COVID-19 infection and venous thromboembolism following common plastic surgery operations.

INTRODUCTION: SARS-CoV-2 (COVID-19) infection has been described as a cause of systemic hypercoagulability and a risk factor for the development of venous thromboembolism (VTE). Whereas some multispecialty studies have proposed a link between COVID-19 and postoperative thrombosis, other single-specialty studies have found no such association. We utilized a large national database to determine whether prior COVID-19 infection was associated with the incidence of VTE following common plastic surgery operations. METHODS: The Merative™ MarketScan® Research Databases were used to identify female patients who underwent index abdominal panniculectomy, breast reduction, autologous breast reconstruction, or implant-based breast reconstruction procedures between 2020 and 2021. International Classification of Disease, tenth edition (ICD-10) codes were used to identify patients diagnosed with COVID-19 preoperatively and those who experienced a VTE in the 90 days postoperatively. Propensity score matching and multivariable logistic regression were used to determine any independent association between COVID-19 and postoperative VTE. RESULTS: Twenty-four thousand two hundred and twenty-eight patients met inclusion criteria. Mean age at time of surgery was 44 years. Six percent carried a preoperative COVID-19 diagnosis, and postoperative VTE occurred in 1.3%. In a propensity-score-matched analysis of 2754 patients, COVID-19 did not significantly correlate with incidence of postoperative VTE (P = 0.463). Compared with a matched prepandemic cohort (14,151 patients), the incidence of VTE did not increase following any of the four studied procedures during the COVID-19 pandemic. CONCLUSION: This analysis of a national insurance claims database provides evidence against a link between resolved COVID-19 infection and VTE within 90 days of four common plastic surgery operations.

Comparative Analysis of Ventral Hernia Repair and Transverse Abdominis Release With and Without Panniculectomy: A 4-Year Match-Pair Analysis.

INTRODUCTION: Amid rising obesity, concurrent ventral hernia repair and panniculectomy procedures are increasing. Long-term outcomes of transverse abdominis release (TAR) combined with panniculectomy remain understudied. This study compares clinical outcomes and quality of life (QoL) after TAR, with or without panniculectomy. METHODS: A single-center retrospective review from 2016 to 2022 evaluated patients undergoing TAR with and without panniculectomy. Propensity-scored matching was based on age, body mass index, ASA, and ventral hernia working group. Patients with parastomal hernias were excluded. Patient/operative characteristics, postoperative outcomes, and QoL were analyzed. RESULTS: Fifty subjects were identified (25 per group) with a median follow-up of 48.8 months (interquartile range, 43-69.7 months). The median age and body mass index were 57 years (47-64 years) and 31.8 kg/m2 (28-36 kg/m2), respectively. The average hernia defect size was 354.5 cm2 ± 188.5 cm2. There were no significant differences in hernia recurrence, emergency visits, readmissions, or reoperations between groups. However, ventral hernia repair with TAR and panniculectomy demonstrated a significant increase in delayed healing (44% vs 4%, P < 0.05) and seromas (24% vs 4%, P < 0.05). Postoperative QoL improved significantly in both groups (P < 0.005) across multiple domains, which continued throughout the 4-year follow-up period. There were no significant differences in QoL among ventral hernia working group, wound class, surgical site occurrences, or surgical site occurrences requiring intervention (P > 0.05). Patients with concurrent panniculectomy demonstrated a significantly greater percentage change in overall scores and appearance scores. CONCLUSIONS: Ventral hernia repair with TAR and panniculectomy can be performed safely with low recurrence and complication rates at long-term follow-up. Despite increased short-term postoperative complications, patients have a significantly greater improvement in disease specific QoL.

En última instancia, la técnica se presenta como una adición al repertorio de procedimientos estéticos abdominales, contribuyendo al avance de la cirugía abdominal estética.

The TULUA abdominoplasty technique, conceived by Dr. Francisco Villegas in Colombia, its acronym in English reflects its fundamental principles: Transverse plication, no Undermined flap above the umbilicus, Liposuction without restrictions including midline and flanks, Neo umbilicoplasty, low scar placement, and free umbilical positioning. Over the past 12 years, the TULUA technique has gained acceptance in Latin America, North America, the Arab region, and India. Highlighting its relevance, the publication of a monographic book has been proposed, its launch is scheduled for 2024, covering from fundamental principles to international experiences with the technique. Indications for TULUA abdominoplasty have evolved, including aesthetic cases, secondary cases, hernias, previous scars, massive weight loss, high definition, muscle augmentation, and combinations with other plications. It has been successfully applied in closing the donor abdomen for breast reconstruction. Through specialized research and peer reviews, TULUA has been recognized for its applicability and benefits, especially in safely performing liposuction during abdominoplasties. Additional studies are suggested to evaluate results and potential complications, opening opportunities for greater understanding and refinement. The future of TULUA abdominoplasty appears promising, anticipating prospective works, additional indications, and a gradual approach for surgeons in training. Ultimately, the technique presents itself as an addition to the repertoire of abdominal aesthetic procedures, contributing to the advancement of aesthetic abdominal surgery.

Perinatal outcomes following abdominoplasty: a retrospective study and review of current literature.

BACKGROUND: Abdominoplasty surgery is a common body contouring surgery to remove excess fat and skin and restore weakened or separated abdominal muscles caused by aging, pregnancy, or weight fluctuations. There is limited literature regarding patient and pregnancy outcomes after abdominoplasty. OBJECTIVE: This study aimed to determine whether there was a correlation between adverse pregnancy outcomes and history of abdominoplasty. STUDY DESIGN: Our study used a large federated deidentified national health research network with data sourced from 68 healthcare organizations within the United States (TriNetX; data accessed on August 19, 2022). All patients with a record of pregnancy were identified using the International Classification of Diseases, Ninth Revision and Tenth Revision, codes and were grouped into those with a history of abdominoplasty and those without. This study evaluated the perinatal outcomes of fetal growth restriction, abnormal umbilical artery Dopplers, gestational hypertension, preeclampsia, preterm delivery, preterm premature rupture of membranes, gestational diabetes mellitus, macrosomia, stillbirth, abnormal placentation, and wound disruption or infection occurring during a patient's pregnancy after abdominoplasty. Propensity matching was performed to account for potential confounders. An alpha level of <.05 was considered statistically significant. RESULTS: Of the 44,737 patients meeting our criteria, 304 had a history of abdominoplasty, whereas 44,433 did not (control). Our study found that patients with a history of abdominoplasty had significantly higher gravidity, were largely located in the Southern and Midwest region, and had higher counts of vaginal deliveries and cesarean deliveries than the control cohort (Table 1). After propensity score matching, our study found a lower risk of preeclampsia and preterm premature rupture of membranes in patients with abdominoplasty (odds ratio, 0.46; 95% confidence interval, 0.32-0.67; P<.0001) (Table 2). Furthermore, abdominoplasty was associated with an increased risk of preterm delivery (odds ratio, 2.15; 95% confidence interval, 1.48-3.13; P=.0002) (Table 2). Lastly, this study did not find significant differences in the other perinatal outcomes (Table 2). CONCLUSION: Our data suggest that abdominoplasty may be associated with a relative increase in the rates of preterm delivery and cesarean delivery and that other perinatal outcomes are not increased. This provides evidence that future desire for pregnancy need not be a relative contraindication to abdominoplasty.

Systemic Tranexamic Acid for Reduced Postoperative Blood Loss and Less Bleeding Complications in Fleur-de-lis Abdominoplasty and Apronectomy.

BACKGROUND: Strategies minimizing surgical bleeding, including the antifibrinolytic agent tranexamic acid, play a crucial role in clinical practice to optimize overall surgical outcomes. Despite its proven efficacy in various clinical fields, there is a limited understanding regarding the use of tranexamic acid in plastic and aesthetic procedures. This study is the first investigating the effects of systemically administered tranexamic acid on postoperative blood loss and bleeding complications in fleur-de-lis abdominoplasties and apronectomies. METHODS: Patients who received 1 g tranexamic acid (n = 44) during fleur-de-lis abdominoplasty or apronectomy were retrospectively compared with those who did not (n = 44). In this context, the outcome parameters 24-h and total drain fluid production, drain time, hospital stay, absolute and relative drop in hemoglobin and hematocrit level as well as bleeding complications such as blood transfusion, hematoma puncture and evacuation were evaluated. RESULTS: Tranexamic acid significantly decreased both drainage volume in 24 h (40.5%, p = 0.0046) and total drain fluid production (42.5%, p = 0.0017). Moreover, a shorter drainage time (19.4%, p = 0.0028) and hospital stay (21.4%, p = 0.0009) were observed. The administration of tranexamic acid was also associated with a reduced postoperative decline in hemoglobin and hematocrit levels. Notably, no bleeding complications were observed in patients who received tranexamic acid, while 6 events occurred in patients without (p = 0.0262). CONCLUSION: Systemic administration of tranexamic acid effectively reduced postoperative blood loss and bleeding complications in fleur-de-lis abdominoplasties and apronectomies.

Effect of Injectable Acellular Adipose Matrix on Soft Tissue Reconstruction in a Murine Model.

BACKGROUND: The extracellular matrix isolated from adipose tissue, known as acellular adipose matrix (AAM), represents a novel biomaterial. AAM functions as a scaffold that not only supports stem cell proliferation and differentiation but also induces adipogenesis and angiogenesis. This study aims to investigate the volumetric effects and microenvironmental changes associated with injectable AAM in comparison to conventional fat grafting. METHODS: AAM was manufactured from fresh human abdominoplasty fat using a mechanically modified method and then transformed into an injectable form. Lipoaspirate was harvested employing the Coleman technique. A weight and volume study was conducted on athymic nude mice by injecting either injectable AAM or lipoaspirate into the scalp (n=6 per group). After eight weeks, graft retention was assessed through weight measurement and volumetric analysis using micro-computed tomography (micro-CT) scanning. Histological analysis was performed using immunofluorescence staining for perilipin and CD31. RESULTS: Injectable AAM exhibited similar weight and volume effects in murine models. Histological analysis revealed comparable inflammatory cell presence with minimal capsule formation when compared to conventional fat grafts. Adipogenesis occurred in both AAM-injected and conventional fat graft models, with no significant difference in the blood vessel area (%) between the two. CONCLUSIONS: In summary, injectable AAM demonstrates effectiveness comparable to conventional fat grafting concerning volume effects and tissue regeneration in soft tissue reconstruction. This promising allogeneic injectable holds the potential to serve as a safe and effective "Off-the-Shelf" alternative in both aesthetic and reconstructive clinical practices.

What Role does Marital Status Play in the Outcome of Abdominoplasties? A Single-Surgeon Experience With 712 Cases.

BACKGROUND: Marital status is a commonly reported demographic variable in scientific literature. Numerous reports suggested difference in the medical outcomes of patients when stratified based on marital status. Although many reports suggested that married patient exhibit improved survival when compared to their counterparts, other reports could not replicate similar conclusions. PURPOSE: determine whether marital status plays a role in the postoperative outcomes of elective abdominoplasty patients. METHODS: The medical records of all abdominoplasty patients operated by a single surgeon over the course of 20 years were reviewed. Information regarding the preoperative state of patients, surgical procedure, and postoperative outcomes was evaluated in respect to the patients marital status. RESULTS: Seven-hundred and twelve patients were included in this study, of whom 516 (%) were married. No difference in preoperative characteristics, medical background, surgical procedure or concomitant surgeries was found. Analysis of adverse events did not demonstrate a statistically significant association with marital status. Additionally, when all unwed patients were grouped together, the results did not differ. CONCLUSION: Marital status does not play a critical role in the postoperative outcomes of patients undergoing elective abdominoplasties for cosmetic indications.

Redefining the Axillary Aesthetic: Surgical Management of Axillary Tissue Hypertrophy.

Background and Objectives: Axillary tissue hypertrophy consists of ectopic breast tissue and occurs in up to six percent of women. Women complain of pain, interference with activity, and dissatisfaction with appearance. While it is recommended that accessory breast tissue be removed via surgical excision, there is lack of consensus on the best technique for the surgical management of axillary tissue hypertrophy. In this study, the senior authors (BC and NT) review outcomes and complications as they pertain to the surgical treatment of axillary tissue hypertrophy and axillary contouring. Materials and Methods: A retrospective review of all patients (n = 35), from two separate institutions, who presented with axillary tissue hypertrophy between December 2019 and August 2021 was conducted. All patients underwent a technique that included direct crescentic dermato-lipectomy and glandular excision with axillary crease obliteration. Tissue was sent for histological analysis after removal. During a six-month follow-up period, all patient outcomes were recorded. Results: The authors treated 35 women with axillary tissue hypertrophy. All patients complained of aesthetic deformity with significant discomfort leading to the desire for surgery. Histologically, all specimens contained benign breast and adipose tissue. Hypertrophic scarring, seroma, and axillary cording were noted complications. Conclusions: Detailed is the surgical management and optimal technique that can be used to treat both adipose and fibroglandular axillary tissue hypertrophy while simultaneously providing a favorable axillary aesthetic.

The effect of liposuction versus liposuction with abdominoplasty on insulin resistance in normoglycemic non-obese Mexican females: A prospective cohort study.

INTRODUCTION: Several studies have evaluated the effect of liposuction or abdominoplasty on metabolic health, including insulin resistance, with mixed results. Many overweight patients, with no marked obesity, are recommended to undergo liposuction combined with abdominoplasty, but no study has evaluated the effectiveness of combining the two procedures on metabolic health. METHODS: The present prospective cohort study compares the metabolic parameters of 2 groups of normoglycemic Hispanic women without obesity. The first group underwent liposuction only (LIPO), while the second group had combined liposuction and abdominoplasty (LIPO + ABDO). RESULTS: A total of 31 patients were evaluated, including 13 in the LIPO group and 18 in the LIPO + ABDO group. The 2 groups had similar HOMA-IR before surgery (P > 0.72). When tested 60 days after surgery, women in the LIPO group had similar HOMA-IR compared to their preoperative levels (2.98 ± 0.4 vs 2.70 ± 0.3; P > .20). However, the LIPO+ABDO group showed significantly reduced HOMA-IR values compared to their preoperative levels (2.37 ± 0.2 vs 1.73 ± 0.1; P < .001). In this group, this decrease also positively correlated with their preoperative HOMA-IR (Spearman r = 0.72; P < .001) and, interestingly, we observed a negative correlation between the age of the subjects and the drop in HOMA-IR after surgery (Spearman r = -0.56; P < .05). No changes were observed in the other biochemical parameters that were assessed. CONCLUSIONS: These data suggest that, when combined with abdominoplasty, liposuction does improve insulin resistance in healthy Hispanic females. More studies are warranted to address this possibility.

Safety and utility of panniculectomy in renal transplant candidates and end stage renal disease patients.

BACKGROUND: As the obesity crisis in the United States continues, some renal transplantation centers have liberalized their BMI criteria necessary for transplant eligibility. More individuals with larger body-habitus related comorbidities with End-Stage Renal Disease (ESRD) now qualify for renal transplantation (RT). Surgical modalities from other fields also interact with this patient population. METHODS: In order to assess surgical outcomes of panniculectomy in the context of renal transplantation and ESRD, the authors performed a systematic review following the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) 2020 guidelines. Due to a paucity of existing primary studies, we retrospectively collected data on patients with ESRD undergoing panniculectomy from the American College of Surgeons' National Surgical Quality Improvement Program (NSQIP) to evaluate outcomes of body contouring in this patient population. RESULTS: From the systematic review, a total of 783 ESRD patients underwent panniculectomy among the studies identified. Of these, 91 patients underwent panniculectomy simultaneously to RT while 692 had their pannus resected prior to kidney transplant. The most common complication was hematoma followed by wound dehiscence. From the NSQIP database, 24 868 patients met the inclusion criteria for analysis. In the setting of renal transplant status, patients with diabetes, hypertension requiring medication, and requiring dialysis were more likely to suffer postoperative complications (OR 1.31, 1.15, and 2.2, respectively). However, upon sub-analysis of specific types of complications, the only retained association was between diabetes and wound complication. CONCLUSION: Preliminary data show that panniculectomy in ESRD patients appears to be safe, though with a nominal increased risk for complications. Pannus resection does not appear to impact post-transplantation outcomes, including long-term allograft survival. Larger, higher powered, randomized studies are needed to confirm the safety, utility, and medical benefit of panniculectomy in the context of renal transplantation.

Effect of Compression Garments on the Ventilatory Function After Abdominoplasty.

BACKGROUND: The use of compression garments in the postoperative period of abdominoplasty seems to be a consensus, but the incidents of complications arising from this have been described, related to an increase in intraabdominal pressure and reduction of the femoral vein blood flow that may facilitate thromboembolic events. There are no studies that have evaluated the isolated effect of postoperative compression garments on respiratory function. OBJECTIVES: The purpose of this study was to evaluate the effect of compression garments on respiratory function after abdominoplasty. METHODS: Thirty-four female patients who underwent standard abdominoplasty were divided into 2 groups, the garment group (n = 18) and the no garment group (n = 16). Respiratory function assessment (with spirometry and manovacuometry) was performed in the preoperative and postoperative periods. RESULTS: Forced vital capacity assessment revealed a greater ventilatory restriction in the garment group. Forced expiratory volume in 1 second (FEV1) showed differences between the evaluation time points in the garment group; the intergroup comparisons showed that the no garment group had a lower FEV1. Slow vital capacity was evaluated with no significant differences found on both intergroup comparisons. The inspiratory capacity was reduced in the garment group, representing ventilatory restriction. Measurements of the maximum inspiratory pressure showed no significant differences between the groups. The maximum expiratory pressure showed significantly lower values on postoperative day 7 in the garment group. CONCLUSIONS: The use of compression garments after abdominoplasty impairs ventilatory function. Not wearing this type of garment can improve ventilation, decreasing the risk of pulmonary complications.

Staged abdominal wall reconstruction in the setting of complex gastrointestinal reconstruction.

PURPOSE: Literature on one- versus two-staged abdominal wall reconstruction (AWR) with complex gastrointestinal reconstruction (GIR) is limited to single-arm case series with a focus on patients who complete all planned stages. Herein, we describe our experience with both one- and two-staged approaches to AWR/GIR, with attention to those who did not complete both intended stages. METHODS: A retrospective review of prospectively collected data was conducted to identify patients who underwent a one- or two-stage approach to GIR/AWR from 2013 to 2020. The one-stage approach included GIR and definitive sublay mesh herniorrhaphy. The two-stage approach included Stage 1 (S1)-GIR and non-definitive herniorrhaphy and Stage 2 (S2)-definitive sublay mesh herniorrhaphy. RESULTS: Fifty-four patients underwent GIR/AWR: 20 (37.0%) underwent a planned 1-stage operation while 34 (63.0%) underwent S1 of a planned 2-stage approach. Patients assigned to the 2-stage approach were more likely to be smokers, have a history of mesh infection, have an enterocutaneous fistula, and a contaminated wound class (p<0.05). Of the 34 patients who underwent S1, 12 (35.3%) completed S2 during the mean follow-up period of 44 months while 22 (64.7%) did not complete S2. Of these, 10 (45.5%) developed hernia recurrence but did not undergo S2 secondary to elective nonoperative management (40%), pending preoperative optimization (30%), additional complex GIR (10%), hernia-related incarceration requiring emergent surgery (10%), or unrelated death (10%). No differences in outcome including SSI, SSO, readmission, and recurrence were noted between the 12 patients who completed the two-stage approach and the 20 patients who completed a one-stage approach, despite increased risk factors for complications in the 2-stage group (p>0.05). CONCLUSION: Planned two-stage operations for GIR/AWR may distribute operative complexity and post-operative morbidity into separate surgical interventions. However, many patients may never undergo the intended definitive S2 herniorrhaphy. Future evaluation of 1- versus 2-stage GIR/AWR is needed to clarify indications for each approach. This work must also consider the frequent deviations from intended clinical course demonstrated in this study.

Patient Characteristics and Spending Among Individuals Undergoing Ambulatory Panniculectomy and Abdominoplasty in the US from 2016 to 2019.

BACKGROUND: Abdominal contouring surgery can provide both functional and cosmetic benefits to patients with abdominal soft tissue laxity. Although these procedures have been studied in the inpatient setting, few studies describe abdominal contouring surgery in the ambulatory setting. OBJECTIVE: The purpose of this analysis was to investigate patterns in patient demographics between functional panniculectomy and cosmetic abdominoplasty using national data from the last four years. METHODS: Using the Nationwide Ambulatory Surgery Sample, we analyzed outpatient abdominal contouring procedures between 2016 and 2019. Encounters with a CPT 15830 were included. Procedures with ICD Z41.1 or CPT 15847 modifiers were defined as cases of cosmetic abdominoplasty. RESULTS: A weighted estimate of 95,289 encounters were included, with 66,531 (69.8%) functional panniculectomy and 28,758 (30.2%) cosmetic abdominoplasty procedures. Among patients with a history of bariatric surgery (23.8%; 95% CI, 22.3-25.4%), there was a 28.5% (4,866 in 2016 vs 6,254 in 2019) increase in panniculectomy and abdominoplasty. Compared with individuals who underwent cosmetic abdominoplasty, individuals who underwent functional panniculectomy were more racially diverse, had more comorbidities, and were more likely to be from low-income backgrounds. CONCLUSIONS: Rates of abdominal contouring surgery in the ambulatory setting have increased in recent years especially among individuals with previous bariatric surgery. There are important demographic and clinical differences between patients who underwent functional panniculectomy and cosmetic abdominoplasty including primary payer, comorbidities, and racial identity.

Physical properties of Scarpa's fascia.

Preservation of Scarpa's fascia has improved clinical outcomes in abdominoplasty procedures and in other body contour surgeries. However, the physical properties of Scarpa's fascia have not yet been described, and grafts are still underexplored. Fresh surgical specimens from five female patients subjected to classical abdominoplasty were dissected and analyzed. A grid was drawn on the fascia surface, dividing it into equal upper and lower halves; four Scarpa's fascia samples (30 × 10 mm) were collected from each half, 40 mm apart. The thickness was measured with a caliper. A strain/stress universal testing machine was used for mechanical tests. Twenty-five samples were obtained (nine from the upper half, 16 from the lower). The average thickness was 0.56 ± 0.11 mm. The average values for stretch, stress, strain, and Young's Modulus were, respectively, 1.436, 4.198 MPa, 43.6%, and 23.14 MPa. The upper half showed significantly greater thickness and strain values (p = 0.020 and p = 0.048; Student's t-test). The physical and biomechanical properties of Scarpa's fascia can make it a donor area for fascial grafts as an alternative to fascia lata, as it is always available and has minimal donor-site morbidity. Further studies are needed to validate this statement. It seems advantageous to use the lower half of the abdomen instead of the upper part as a donor site.

Do Small Scars Lead to Better Results? Analysis of Long-term Outcomes and Satisfaction of Patients Undergoing Anchor-line Abdominoplasty Following Massive Weight Loss.

INTRODUCTION: Do smaller scars lead to higher patient satisfaction? The aim of this study is to analyze long-term satisfaction of patients who underwent abdominoplasty after massive weight loss. METHODS: Patients inclusion criteria: no previous abdominal remodeling procedures, previous bariatric surgery followed by a weight loss of at least 30 kg, weight stability for at least one year, good understanding of the Italian language and standardized pre- and postoperative photographs. We divided the population in 2 groups based on the surgical procedure: group 1, conventional abdominoplasty, and group 2, anchor-line abdominoplasty. All patients presented scars in the epigastric and mesogastric region resulting from previous laparoscopic or laparotomic bariatric surgery and/or other laparoscopic or laparotomic procedures. At least 2 years after surgery, we administered the Italian version of the post-operative BODY-Q module and the SCAR-Q questionnaire. RESULTS: We enrolled 20 males and 69 females aged between 25 and 55 years, with a mean follow-up of 2 years. Analyzing the questionnaires, it resulted that patients undergoing anchor-line abdominoplasty were significantly more satisfied in the body perception of the result (p = 0.035) and in the satisfaction with abdomen domain (p = 0.0015) compared to the conventional abdominoplasty group. Scars assessment with the SCAR-Q did not show any significant differences between the groups. CONCLUSION: Despite its long scars, the anchor-line pattern shows an overall higher satisfaction, due to the possibility of reducing the abdomen both cranio-caudally and circumferentially. These findings might be an important guide when approaching abdominoplasty in post-bariatric patients, debunking the myth "shorter is better".
