Can AI Answer My Questions? Utilizing Artificial Intelligence in the Perioperative Assessment for Abdominoplasty Patients.

BACKGROUND: Abdominoplasty is a common operation, used for a range of cosmetic and functional issues, often in the context of divarication of recti, significant weight loss, and after pregnancy. Despite this, patient-surgeon communication gaps can hinder informed decision-making. The integration of large language models (LLMs) in healthcare offers potential for enhancing patient information. This study evaluated the feasibility of using LLMs for answering perioperative queries. METHODS: This study assessed the efficacy of four leading LLMs-OpenAI's ChatGPT-3.5, Anthropic's Claude, Google's Gemini, and Bing's CoPilot-using fifteen unique prompts. All outputs were evaluated using the Flesch-Kincaid, Flesch Reading Ease score, and Coleman-Liau index for readability assessment. The DISCERN score and a Likert scale were utilized to evaluate quality. Scores were assigned by two plastic surgical residents and then reviewed and discussed until a consensus was reached by five plastic surgeon specialists. RESULTS: ChatGPT-3.5 required the highest level for comprehension, followed by Gemini, Claude, then CoPilot. Claude provided the most appropriate and actionable advice. In terms of patient-friendliness, CoPilot outperformed the rest, enhancing engagement and information comprehensiveness. ChatGPT-3.5 and Gemini offered adequate, though unremarkable, advice, employing more professional language. CoPilot uniquely included visual aids and was the only model to use hyperlinks, although they were not very helpful and acceptable, and it faced limitations in responding to certain queries. CONCLUSION: ChatGPT-3.5, Gemini, Claude, and Bing's CoPilot showcased differences in readability and reliability. LLMs offer unique advantages for patient care but require careful selection. Future research should integrate LLM strengths and address weaknesses for optimal patient education.

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.

Age Is Just a Number? The Impact of Age on Abdominoplasty Outcomes: A Single Surgeon Experience.

BACKGROUND: Abdominoplasty is among the most popular aesthetic procedures in plastic surgery worldwide. Common indications include prior massive weight loss, surgical or not, with remaining skin excess and post-pregnancy women looking to restore their youthful abdominal contour. Aging of the worldwide population results in a greater number of older patients interested in aesthetic procedures. Identifying the impact of age on abdominoplasty outcomes is crucial in ensuring the safety of care and determining sub-optimal patients that might not benefit from the procedure. MATERIALS AND METHODS: Medical records of all abdominoplasty patients operated by the senior author were screened for appropriate patients. Patients were excluded from the study if the mandatory follow-up time was not met or in instances of incomplete medical records. Patients were further stratified into 5 age groups based on age and compared using pre-operative, intra-operative and post-operative characteristics. Further regression analysis was performed to estimate the risk of complications for each individual age group, in an unadjusted and adjusted model. RESULTS: Six hundred and seventy-three patients were included in the study. Statistically significant differences were noted between the groups in respect smokers, prior bariatric surgery, and hypertension, diabetes mellitus and dyslipidemia (p values <0.01). Seroma rates, were greatest in the oldest age group (P value = 0.039). Odds ratio of 3.3 was calculated for seroma development in patients aged greater than 60. In a multivariate analysis, the risk diminished and was found to be statistically insignificant. CONCLUSION: Abdominoplasty is a safe procedure in all age groups. Increased rates of specific complications must be assessed in relation to potential confounders that exist between different age groups.

Comparing the Outcomes of Scalpel and Diathermocoagulation Dissection in Abdominoplasty: A Systematic Review and Meta-Analysis.

BACKGROUND: Abdominoplasty, an emerging surgical procedure worldwide, associated with complications, as seroma, infection, and hematoma. This systematic review and meta-analysis compare the outcomes of abdominoplasty procedures performed using a scalpel versus a diathermocoagulation device (diathermy monopolar electrocautery), aiming to find a safer approach with fewer complications. METHODS: We conducted a systematic search in November 2023 using PubMed, Ovid Medline, and Ovid Chocrane databases. The methodological index for nonrandomized studies and the Revised Cochrane Risk of Bias assessment tools were used to assess risk of bias for observational studies and randomized controlled trials, respectively. The data were analyzed using RevMan software. RESULTS: Six articles (1135 patients) were included, 521 patients were operated using a scalpel and 614 using electrocautery. Our analysis suggests that both seroma and drain output were seen more among the electrocautery group, with an odds ratio (OR) of 0.62 (95% CI [0.39, 0.97], p = 0.04) and - 103.63 (95% CI [- 205.67, - 1.59], p = 0.05), respectively. It is important to note the high heterogeneity seen among the studies discussing the total drain output. Additionally, we did not find any statistical significance between both techniques in terms of the rate of hematoma, wound infection, operation time, and hospital stay length. CONCLUSION: When comparing the use of scalpel and electrocautery dissection in abdominoplasty, higher rates of seroma and total drain output are significantly associated with electrocautery dissection.

Influence of Tranexamic Acid in Body Contouring Surgery: Significant Changes on Complication Rates after Abdominoplasty.

BACKGROUND: Complications after abdominoplasty remain an unsolved issue in body contouring surgery. The antifibrinolytic drug tranexamic acid (TXA) has gained increasing recognition as a valuable pharmacologic agent within plastic surgery. The aim of this study was to investigate the influence of intravenously administered TXA on complications and patient safety after abdominoplasty. METHODS: Within this retrospective single-center study, patients who underwent abdominoplasty and received intravenous TXA were selected and compared to randomly selected patients who underwent abdominoplasty without administration of TXA. The patient population was divided into two study groups (TXA vs no TXA). Demographic and surgical data as well as complications were evaluated and compared. Appropriate statistical analysis was performed. RESULTS: Fifty-seven female and 3 male patients with a median age of 38 years and a mean BMI of 25.6 ± 3.3 kg/m2 were included in the study. Except smoking history, demographic data showed no statistically significant differences between both groups. The most common complication was seroma formation (n = 16; 23.9%), and its occurrence was statistically significantly lower in the TXA group (p = 0.023). Furthermore, postoperative seroma aspiration was performed in statistically significant lower numbers in the TXA group (p < 0.05). No thromboembolic events or seizures were observed. DISCUSSION: The outcomes of this study showed that the intravenous administration of TXA leads to a significant reduction of seroma formation and postoperative seroma aspiration after abdominoplasty. Simultaneously, no adverse thromboembolic events were detected. Hence we would recommend administration of TXA in body contouring surgery to decrease the incidence of seroma formation.

Retrograde Umbilical Hernia Repair During Abdominoplasty: A Safe and Simple Technique.

BACKGROUND: Abdominoplasties are a very common procedure that is geared toward improving the abdominal contour and restoring quality of life. Main candidates for surgery are postpartum patients and patients after massive weight lost results in excess skin. The high incidence of umbilical hernias in the general population raises the question of whether combining its repair with cosmetic abdominoplasties is a safe and effective procedure. PURPOSE: Determine the safety of the "retrograde umbilical hernia" (RUH) technique, which utilizes a pre-peritoneal approach to the hernia, during abdominoplasty procedure and expand the literature on hernia repair during aesthetic abdominal surgery. METHODS: This is the retrospective cohort study of all patients that underwent abdominoplasty by the senior author. Eligible patients were divided into 2 groups: where one group included all patients who underwent abdominoplasty with RUH repair, and the second group underwent sole abdominoplasty. Baseline variables, surgical notes, and post-operative outcomes were obtained from the patients' medical records and analyzed for the purpose of this study. RESULTS: In total, 744 patients underwent abdominoplasties during the course of our study, 112 of which underwent concomitant umbilical hernia repair using the retrograde technique. The RUH technique was not found to result in a higher rate of complications compared to a similar population of traditional abdominoplasties. CONCLUSIONS: The retrograde umbilical hernia repair is a safe and efficient technique that can be easily implemented during abdominoplasty procedures in a heterogeneous population of patients.

Navigating Aesthetic Pursuits: A Google Trends Insight into Cosmetic Tourism.

BACKGROUND: The popularity of cosmetic tourism may increase unnecessary risks for patients as postoperative care is variable. However, little is known about the current trends and public perception of this growing phenomenon. This study compares interest in cosmetic tourism in popular medical tourism destinations relative to the US. METHODS: Google Trends was queried from October 2017 to September 2023, examining trends over the full period and dissecting changes between 2017-2020 and 2020-2023. Search volume data were retrieved for the top international countries and the US for each of the top five cosmetic procedures, according to the ISAPS 2022 Global Survey. A p value < 0.05 was used for statistical significance. RESULTS: Searches for liposuction, blepharoplasty, breast augmentation, mastopexy, and abdominoplasty were compared between the US, Mexico, Turkey, Thailand, and Colombia. Google Trends data mirrored the prevalence of the two most common procedures, liposuction, and breast augmentation. Differences in interest regarding liposuction were greatest in Mexico, Thailand, and Turkey compared to the US (p < 0.05). Medical tourism for blepharoplasty had the highest search interest scores for Turkey and Thailand from 2017 to 2023 (p < 0.05). Significant differences were also consistent across all time intervals for breast augmentation, mastopexy, and abdominoplasty, with higher interest in Mexico and Turkey (p < 0.05). CONCLUSIONS: Google Trends analysis serves as an insightful tool for understanding cosmetic tourism. Changing trends bring the potential to assess worldwide versus country-specific procedure interest. These observed trends may foreshadow future international aesthetic procedure trends.

Standardization of the Extent and Timing of Rectus Diastasis Repair in Abdominoplasty Cases with TOF Neuromuscular Monitoring: A Clinical Study.

Despite the close focus on the anterior abdominal wall and the classification, maneuvers and materials related to the rectus abdominis and its fascia, there is no established standard concerning the extent of plication. The anterior abdominal wall is a musculoaponeurotic structure and a dynamic motor system with innervation and tonus. Therefore, the timing of the plication is as important as the suture technique and material, since the muscle relaxant will lose its effect in varying time periods. The aims of our study were to determine the change in the amount of plication between groups with and without muscle relaxants before plication and whether the amount of this change can be standardized using train-of-four (TOF) monitoring. In 2022 and 2023, 12 women aged between 25 and 48 years with a body mass index between 24 and 38 years were included in the study. Neuromuscular blockade was monitored by train-of-four (TOF) monitoring in all patients. Maximum plication areas at above-zero TOF value and zero TOF value were calculated and compared with each other. The reduction in the area of group 1, which represents the phase without muscle relaxant, and group 2, which represents the phase with neuromuscular blockade, were compared using the t-test. When assessed for above-zero TOF, the area between plication lines (a, a') was always smaller than the area between the plication lines (b, b') when the TOF value was zero. The t test comparison of group 1, which includes (a, a') values, and group 2, which includes (b, b') values, resulted in a value of p = 0.000. All cases, the plication value obtained with above-zero TOF value was lower than the plication value when the TOF value was zero. This difference was also confirmed statistically on a group basis. This suggests that neuromuscular measurements should be taken during the plication phase in the routine flow of surgery. Muscle relaxants are not routinely administered to patients undergoing abdominoplasty or rectus diastasis repair who are already under sufficient analgesia, unless there is a pressure alert on the anesthesia device. The surgeon cannot always determine the degree of muscle laxity accurately by palpation. TOF monitoring is a cost-effective quantitative method that can be easily and quickly performed, accurately determining the timing of muscle-fascia plication of the rectus abdominis. Through this approach, the anterior abdominal wall can be plicated with maximum tightness and maximum aesthetic gain can be obtained.Level of Evidence V This journal requires that authors assign a level of evidence to each article.

Outcomes of Abdominoplasty in Tumescent Local Anesthesia Combined with Subdural Anesthesia.

BACKGROUND: Abdominoplasty is a common surgical procedure performed under general anesthesia, and although the use of TLA combined with subdural anesthesia has never been reported in abdominoplasty, it offers several benefits such as safe and effective local anesthesia and vasoconstriction. We outline our experience with the TLA technique for primary abdominoplasty over the last 7 years. METHODS: From 2014 to 2021, TLA and subdural anesthesia have been used in primary abdominoplasty surgeries for 106 patients. The TLA solution consisted of 25 mL of 2% lidocaine, 8 mEq of sodium bicarbonate, and 1 mL of epinephrine (1 mg/1 mL) diluted in 1000 mL of 0.9% saline solution. The solution was then injected with a 2-mm cannula into the subcutaneous adipose tissue in the suprafascial plane. The subdural anesthesia was performed at intervertebral level L1-L2 using Ropivacaine 15/18 mg in 4 ml. RESULTS: Patients aged from 32 to 75 years. The amount of tumescent solution infiltrated ranged between 500 and 1000 mL. Mean surgery time was 70 minutes, and recovery room time averaged at 240 minutes. Major complications related to the surgery were observed in 12.26% of patients, including eight hematomas and five seromas. Two patients experienced wound dehiscence, and no dystrophic scar formation was observed. Eventually, there was no need for a conversion to general anesthesia. CONCLUSIONS: Tumescent local anesthesia combined with subdural anesthesia is a highly effective and safe method for performing abdominoplasty. This technique has proven to be an excellent choice for primary abdominoplasty, providing significant benefits to patients and surgeons alike due to its safe administration, precise pain management during and after surgery, and minimal postoperative side effects.

Exploring Complication Rates: A Comparative Study of Breast Reduction and Combined Breast Reduction with Abdominoplasty.

BACKGROUND: Despite a trend towards combining abdominoplasty with breast reduction surgery, so called "mommy makeovers", the safety of this combined approach has been the subject of debate, with previous research yielding conflicting results. We evaluated the risk for complications and revision associated with adding abdominoplasty to bilateral breast reduction surgery. METHODS: We conducted a 10-year single-center retrospective chart review of bilateral breast reduction patients in Nova Scotia. Univariate and multivariate analyses were performed to compare the risk for complication and revision in patients with bilateral breast reduction to those with a concomitant abdominoplasty. RESULTS: Of the 1871 patients initially screened, 738 were included. 44 underwent a concomitant abdominoplasty procedure. Compared to the breast reduction alone group, patients with concomitant abdominoplasty were significantly older (47.5±9.9 vs. 42.8±13.2, p=0.004), had a higher BMI (28.1±4.4 vs. 25.8±3.1, p<0.001), and experienced longer operating room times (226±6 vs. 115±3 mins, p<0.001). In multivariate analysis, concomitant abdominoplasty did not increase the risk for breast-related (OR: 0.86 95%CI 0.43-1.7, p=0.668) or total complications (OR: 1.63, 95%CI 0.83-3.19, p=0.154). However, there was a trend towards an increased risk of breast revision (OR: 2.684, 95%CI 0.95-7.6, p=0.062) and a significantly increased risk of total revision (OR: 6.624, 95%CI 2.7-16.1, p<0.001). Moreover, patients with concomitant abdominoplasty experienced more follow-up visits (median: 4 vs. 3 visits, p=0.042). CONCLUSION: In our single-center retrospective analysis, combining abdominoplasty with bilateral breast reduction did not increase the risk for breast, or total complications; however, it did increase the risk for total revisions.

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".

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.

Redefining Abdominal Contours: An Analysis of Medium Definition Liposuction Abdominoplasty.

INTRODUCTION: This study elucidates the application of Medium Definition Liposuction Abdominoplasty, a novel technique for achieving well-defined abdominal contours. The technique focuses on revealing the patient's inherent muscular volume and form by creating thinner flaps compared to traditional liposuction methodologies. METHODS: Objective evaluations of the abdominal wall's configuration were systematically executed both pre- and post-intervention for each participant. Digital image measurements facilitated by an image software constituted the basis for these assessments. The Body Fat Index was computed using precise measurements from seven distinct anatomical sites, with two measurements taken at each site and subsequently averaged. RESULTS: Over a span of 63 months, 300 patients underwent this combined procedure, resulting in discernible enhancements in the configuration of their abdominal walls in 97.6% of cases. However, complications such as partial diminution of tension in the muscular wall (2%), distal flap necrosis (0.6%), and minor muscular hernia (0.3%) were observed. CONCLUSION: The employment of combined muscle plication emerges as an efficacious methodology in meticulously rectifying alterations inherent within the muscular aponeurotic abdominal wall. This technique ensures the preservation of the original anatomical structure and functional dynamics, thereby circumventing the manifestation of local distortions that may arise from inadequate or excessive corrections.

Patient Weight and Chemoprophylaxis in Abdominoplasty: Does It Result in More Bleeding Events?

BACKGROUND: Bariatric surgery has gained popularity in recent decades as an effective treatment for obesity. Abdominoplasty is one of the most often performed aesthetic procedures all over the world. In post-bariatric patients undergoing abdominoplasty, the diameter size and number of the abdominal wall perforators increase proportionally with increased body weight. Postoperative complications that may occur are haematoma, and venous thromboembolism (VTE). In plastic surgery procedures VTE prophylaxis grades vary due to the lack of consensus and clear guidelines. The aim of this study was to explore the frequency of postoperative bleeding and VTE in patients undergoing abdominoplasty and to explore the risk factors associated with major bleeding. METHODS: A retrospective single-centre study of adult patients who were operated on by abdominoplasty between 2011 and 2020. Chemoprophylaxis including low molecular weight heparin (LMHW) was recommended when the operating time exceeded 2 h. RESULTS: A total of 102 patients were included. There were no patients with VTE. Eight patients were re-operated for major haematoma. The weight loss (peak weight to weight before the abdominoplasty) was 14.4 kg larger in the re-operation group (p = 0.03). Eighty-eight percent in the re-operation group and 67% in the other group were treated with LMWH (p = 0.43). Multivariable logistic regression showed that with each decrease from the peak in BMI kg/m2 the risk of re-operation for major haematoma was increased by 22% (p = 0.02). CONCLUSION: Abdominoplasty in patients after massive weight loss has a higher risk of postoperative bleeding. Having a clear protocol for chemoprophylaxis should be considered.

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.

Could Abdominoplasty with Diastasis Recti Abdominis Correction Improve Stress Urinary Symptoms? A 1-Year Follow-up Prospective Study.

BACKGROUND: Diastasis recti abdominis (DRA) indicates an abnormal separation of the rectus abdominal muscles from the midline, resulting in abdominal bulging. Recent literature shows a correlation between DRA and back pain, stress urinary incontinence. Primary goal of this study is to check the correlation between DRA correction in abdominoplasty and improvement of urinary symptoms. MATERIALS AND METHODS: This is a prospective study on patients with post-pregnancy rectus diastasis who underwent surgical correction of diastasis through conventional abdominoplasty. All patients were asked to complete the ICIQ-FLUTS questionnaire, which assesses urinary disorders, and the SF-36 questionnaire, aimed at quantifying health-related quality of life. The questionnaires were administered to patients the day before surgery and one year after surgery. RESULTS: The recruited patients (n = 51) were then stratified on the presence or absence of stress urinary incontinence. Of the 39 patients with preoperative incontinence, the average scores of the ICIQ-FLUTS were analyzed. In particular, for the questions relating to stress urinary incontinence a statistically significant difference was reported between the preoperative mean and the 1-year mean for all questions (p value<0.05). As regards quality of life, comparing the average scores of each question of SF-36 there is an improvement in the values of all the variables of the questionnaire. CONCLUSION: The strength of this study, which distinguishes it from other literature, is that the changes in abdominal pressure post-abdominoplasty which should lead to a worsening of stress incontinence, do not cause it. On the contrary, we have demonstrated the improvement of this symptom after conventional abdominoplasty surgery in most patients.

Drains in Abdominoplasties: The Less the Better?

BACKGROUND: Drains are traditionally inserted during surgery for reduction of fluid accumulation in the post-operative period. The appearance of drained fluids and their quantity can be early predictors of complications. Over the years, several studies have been conducted in attempt to determine the optimal number of drains that result in low rates of fluid accumulation with minimal impairment of quality of life. PURPOSE: Determine the optimal number of suction drains in abdominoplasty procedures. METHODS: Retrospective cohort study, analyzing all abdominoplasty patients operated by a single surgeon. Patients were stratified into 3 groups based on number of drains inserted at the end of the procedure. Rate of complications was compared between the groups and a multivariate logistic regression model was computed for the development of complications. RESULTS: Seven-hundred and forty three patients were included in the analysis of this study. No drains were inserted in 355 patients (45%), whereas a single drain was inserted in 153 (20.6%) 2 drains in 255 patients (34.4%). Patients for whom a single drain was inserted intra-operatively, experienced at a statistically significant lower rate, surgical site infections (OR = 0.235), hypertrophic scars (OR = 0.326), wound dehiscence (OR = 0.272), as compared to patients with no drains. On the contrary, insertion of single drain was associated with a statistically significant higher risk for development of seroma (OR = 6.276) and the need for revision surgery (OR = 2.452). CONCLUSION: Insertion of a single drain is associated with a lower risk of SSI and wound- dehiscence, but a greater risk for seroma development that requires surgical intervention.

The Preservation of Umbilical Blood Supply in Combined Ventral Hernia Repair and Abdominoplasty: A Narrative Review.

INTRODUCTION: Combined ventral hernia repair and abdominoplasty treat risk factors such as high body mass index and weak abdominal musculature, providing excellent intraoperative exposure and improved patient outcomes. Unfortunately, a combination of traditional procedures is unfeasible as the umbilical blood supply would be compromised, leading to increased umbilical necrosis risk. This narrative review aimed to identify new techniques and solidify evidence in preserving umbilical blood supply and associated level of evidence. METHODS: Two authors conducted a thorough literature search on PubMed, Scopus and Cochrane CENTRAL databases from January 1901 to July 2023, adhering to the methodologies of the preferred reporting items for systematic reviews and meta-analyses. Studies were reviewed for their surgical technique and quality of evidence. The primary outcomes of interest consisted of umbilical complications of this combined procedure. RESULTS: Six techniques were identified that included laparoscopic, pre-rectus, unilateral, distal bilateral, proximal bilateral, and inferior midline approaches. All techniques demonstrated as viable options in preserving umbilical blood supply as reported complications were few, minor, and compounded by risk factors. However, all included techniques were limited to low-to-moderate-quality evidence. CONCLUSION: Despite the lack of high-quality evidence, all techniques remain viable options for combined ventral hernia repair and abdominoplasty. Large-scale high-quality RCTs are required to compare the effectiveness of various approaches with additional outcomes of hernia recurrence rates, intraoperative time, and patient- and surgeon-reported satisfaction.

The Impact of Metabolic Syndrome on Postoperative Outcomes in Abdominal Body Contouring: A Propensity Score-Matched Nationwide Analysis.

BACKGROUND: Metabolic syndrome (MetS) represents cardiometabolic dysregulation, defined by hypertension, obesity, diabetes, and dyslipidemia. There remains a significant gap in our understanding of whether MetS impacts outcomes of abdominal body contouring procedures. We aimed to assess the influence of MetS on postoperative outcomes of abdominal body contouring by concurrent abdominoplasty and panniculectomy. METHODS: The ACS-NSQIP database was utilized to identify patients who underwent concurrent abdominoplasty and panniculectomy procedures from 2012 to 2022. Through propensity score matching, distinct cohorts were established based on the presence of MetS, characterized by patients receiving medical interventions for diabetes mellitus and hypertension, with a body mass index exceeding 30 kg/m2. Univariate and multivariate analyses were conducted to evaluate differences between groups. RESULTS: A total of 14,642 patients underwent abdominal body contouring from 2012 to 2022. Following propensity score matching, 730 patients were included in the analysis, with 365 in each group (MetS vs. non-MetS). Bivariate analysis revealed a longer hospital length of stay (2.3 vs. 1.6 days; p = 0.007) in the MetS cohort compared to the non-MetS cohort. Patients diagnosed with MetS had an average length of stay of 0.6 days longer than non-MetS patients (95% CI [0.17, 1.01]; p = 0.007). No noteworthy disparities were observed in the rates of 30-day wound complications, mild systemic, and severe systemic complications, and readmission rates between the groups. CONCLUSIONS: Our findings suggest that abdominal body contouring remains a secure option for patients with MetS. Nonetheless, the longer hospital length stays observed in patients with MetS may translate to increased overall costs to the healthcare system. Continued research is warranted to comprehensively assess the economic implications of MetS in the context of abdominal body contouring.

Comparative analysis of the efficacy and functionality of abdominoplasty versus minimally invasive techniques in the surgical treatment of diastasis rectus abdominis in postpartum women.

INTRODUCTION: This review aims to describe the surgical options available for treatment of diastasis recti in postpartum women, as well as compare the effectiveness of these treatment options. Historically, diastasis recti has been repaired through open procedures, such as abdominoplasty. More recently, studies have explored other methods for the treatment of diastasis recti, including various minimally invasive surgical options. METHODS: Twelve studies ranging from 2015 to 2022 were included in this analysis. Studies were identified using PubMed, EMBASE, and Cochrane Library. Studies that met the inclusion criteria were analyzed descriptively. Statistical comparison of surgical outcomes between studies was performed using Fisher's Exact Test in SPSS. RESULTS: Minimally invasive approaches were categorized as laparoscopic preaponeurotic approaches, robotic approaches, and enhanced-view/extended totally extraperitoneal (eTEP) approaches. These techniques were compared to two open approaches: abdominoplasty and miniabdominoplasty. There were no significant differences in the rate of seromas, surgical site infections/complications, or hematomas between abdominoplasty and minimally invasive surgical techniques (p > 0.05). Among the minimally invasive techniques, no significant differences in readmission rates were reported (p > 0.05). Additionally, no significant differences in recurrence rates were seen following minimally invasive or abdominoplasty repairs, except for the increased recurrence rates seen with the r-TARRD robotic technique (p < 0.05). CONCLUSION: Although current data on minimally invasive approaches is limited, our review reveals that both open and minimally invasive approaches are viable options for diastasis recti repair in postpartum women. Identifying the optimal approach for diastasis recti repair should rely on the patient's desired treatment outcome. If the patient indicates a desire for the removal of excess abdominal subcutaneous tissue, abdominoplasty may be a better surgical approach. Alternatively, if the patient puts a greater emphasis on shorter recovery time and smaller surgical incisions/scars, minimally invasive approaches may be a better surgical option.
