Post-Bariatric Abdominoplasty: Analysis of 406 Cases With Focus on Risk Factors and Complications

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.

Experience in Post-Bariatric Abdominoplasty for Patients with Significant Weight Loss: A Prospective Study

BACKGROUND

Abdominoplasty is a critical aesthetic and functional procedure for individuals who have undergone massive weight loss. Numerous techniques have been proposed to optimize aesthetic results while minimizing complications.

METHODS

This prospective study examined 500 patients who underwent abdominoplasty during body-contouring procedures between 1 January 2018 and 31 December 2021 at a tertiary center. The Skin-Adipose Tissue-Muscle (SAM) protocol was employed to analyze the operative strategies and complication rates and compare them with the existing literature. Furthermore, patient satisfaction and aesthetic outcomes were measured one year post-operation using a comprehensive four-point questionnaire evaluated by the patients themselves and two independent surgeons.

RESULTS

Participants had an average age of 34.8 years and a mean BMI of 31.1 kg/m2. The surgeries included 328 full abdominoplasties and 172 T-inverted abdominoplasties. Notable complications included wound infection (4%), wound dehiscence (8.6%), tissue necrosis (0.6%), seroma (8.4%), and hematoma (2.6%). A higher BMI was correlated with an increased risk of complications and lower patient satisfaction. Data analysis was performed using Stata version 18 software.

CONCLUSIONS

The increasing prevalence of obesity highlights an urgent need for more bariatric surgeries and subsequent abdominoplasties to mitigate the effects of massive weight loss. A crucial link between elevated BMI and a heightened risk of postoperative complications, emphasizing the necessity for standardized surgical protocols tailored to individuals with higher BMI, was noted. Innovatively, future studies must further investigate the intricate dynamics between BMI and surgical risks. Exploring and establishing uniform, adaptive surgical guidelines promise to revolutionize patient care by significantly reducing complications and enhancing recovery and satisfaction following abdominoplasty.

Multidisciplinary combined treatment based on bariatric surgery for metabolic syndrome: a review article

As a chronic, multifactorial disease, obesity is associated with a global social and economic burden. This condition significantly affects normal daily life and healthy social interactions, and shortens the life expectancy of patients. Compared with traditional weight-loss methods, the emergence of bariatric surgery has effectively improved the management of obesity. Furthermore, bariatric surgery can also inhibit the progression of multiple metabolic diseases. Despite its potential advantages, bariatric surgery cannot completely eliminate the possibility of weight regain and inadequate weight loss following the procedure. For super-obese patients, bariatric surgery still remains a surgical risk. In addition, the psychological problems and poor eating habits of obese patients also affect the weight loss effect and daily life. Thus, various adjuvant therapies involving multiple disciplines have attracted people's attention. Recently, it has been recognized that the combination of multiple interventions based on bariatric surgery is more advantageous than a single intervention in alleviating the complex and diverse metabolic diseases associated with obesity. The combined therapy considerably enhances the long-term efficacy of bariatric surgery and plays a positive role in the mental health and social lives of patients. In this article, the authors review this multidisciplinary combination therapy to enhance the current understanding of the treatment of obesity.

A Procedure and Complication-Specific Assessment of Smoking in Aesthetic Surgery: A Systematic Review and Meta-Analysis

Background: The popularity of aesthetic surgery is on the rise, as is patients' expectations towards excellent surgical results. In order to meet these expectations, risk factors that hinder desired outcomes, such as smoking, need to be identified and addressed. To that end, the present study summarizes an updated systematic review focused on the effects of smoking on cosmetic surgical procedures and outcomes. Methods: A systematic review of studies comparing aesthetic surgical outcomes by procedure, between tobacco smokers and non-smokers was carried out, querying PubMed, Embase and the Cochrane databases. Data regarding surgical outcomes were extracted and meta-analyzed by a random effects model in conjunction with the Mantel-Haenszel statistical method. Results: Eighty-two studies were included in the final synthesis. Abdominoplasty/panniculectomy (n = 19 cohorts) and breast reduction (n = 27 cohorts) were the most common types of procedures included in this review. Other than mastopexy and rhinoplasty, smoking conferred a statistically significant increased risk of overall complications for all studied aesthetic procedures. Conclusions: The data demonstrates that smoking is a clear risk factor for the vast majority of aesthetic plastic surgeries studied. Although our meta-analysis suggests that smoking is not a risk factor for complications in mastopexies and rhinoplasties, these two specific analyses may have been biased, and should therefore be re-evaluated with future additional evidence. The results of this systematic review confirm the importance of smoking cessation and education relative to the outcomes of common cosmetic surgical procedures.

[Increased risk of bleeding during abdominal dermolipectomies in men: Myth or reality?]

INTRODUCTION

Abdominoplasty is the most frequently performed procedure for the treatment of weight loss sequelaes. It carries risks of complications, especially in patients with multiple metabolic comorbidities. It is commonly accepted that the male population develops more postoperative complications, particularly haemorrhage, but there are very few studies showing this excessive morbidity. The aim of this study was to determine the increased risk of bleeding after anterior and circular abdominoplasty in men by comparing two series of 105 male and female patients.

MATERIALS AND METHODS

This is a retrospective, single-center study including 105 male subjects undergoing simple or circular abdominoplasty between 2013 and 2022. The control group was composed of 105 women screened on the same terms. The data collection focused on different pre-, intra-, and postoperative variables, with the occurrence of a hematoma or the need for a transfusion during follow-up as the primary outcome. The analysis was performed according to a univariate and multivariate models.

RESULTS

The rate of hematoma or transfusion, seroma, infection, amount of blood loss, and length of hospital stay were significantly greater in the male group. Multivariate analysis confirmed the independence of gender on the risk of developing a hematoma or requiring a transfusion.

CONCLUSION

This study shows the excess morbidity in men, particularly haemorrhage, after abdominoplasty. This underlines the importance of a rigorous haemostasis and follow-up in this at risk population.

Post-Bariatric Plastic Surgery: Abdominoplasty, the State of the Art in Body Contouring

Due to the increased prevalence of obesity in the last decades, bariatric surgery has been on the rise in recent years. Bariatric surgery is a compelling option for weight loss in obese patients with severe obesity-related comorbidities or for whom lifestyle modifications have proven ineffective. Redundant skin following significant weight loss is a common occurrence affecting up to 96% of patients who undergo bariatric surgery, negatively impacting physical and psychosocial health and detracting from activities of daily living. Statistics of the American Society of Plastic Surgeons show that 46,577 body contouring procedures were performed after massive weight loss in the USA in a 2020 report. Abdominoplasty, a well-established cosmetic surgery procedure for improving body contour, is performed by removing excess skin and fat from the abdominal wall and thereby restoring musculofascial integrity and skin elasticity, resulting in a more ideal body shape and increasing quality of life. Although abdominoplasty is a safe procedure, it has been associated with a higher complication rate compared with other body-contouring procedures. Technologic advances over the past decade have been developed as non-invasive alternatives or adjunctive tools to surgery to enhance cosmetic results and minimize complications. New energy-based technologies may supplant invasive surgery for mild to moderate skin laxity and/or diminish the extent of surgery and resulting scars. Plastic surgeons play a significant role in improving the quality of life of patients who suffer from obesity and underwent bariatric surgery. We are deeply convinced, however, that the advancement of knowledge and research in this field will determine the introduction of new technologies and custom-made techniques. This advancement will reduce the complication rate with a rapid reintegration of the patient into the world of work and resumption of daily activities.

[Lipoabdominoplasty in post-bariatric Surgery: a relevant Alternative to Fleur-de-Lis abdominoplasty?]

BACKGROUND

The number of bariatric procedures, and thus also the number of post-bariatric operations, has increased dramatically in recent years. Although long scars are common in post-bariatric surgery and accepted in favour of body shape reconstruction, we increasingly notice the wish for aesthetically pleasing results in addition to the desire for body contouring. In particular, Fleur-de-Lis abdominoplasty (FdL) is viewed critically by younger patients after massive weight loss due to the visible vertical scar. Surgeons are also often bothered by the unsatisfying aesthetic outcome as well as the higher rate of complications.

METHODS

Retrospective analysis of 20 female patients with massive weight loss following bariatric surgery, who received lipoabdominoplasty instead of Fleur-de-Lis abdominoplasty in the period from January 2019 to June 2020. Data analysis was based on measurements of preoperative vertical and horizontal excess skin and fat (Pittsburgh Rating Scale), Body Mass Index, surgical technique and final result.

RESULTS

Twenty female patients with an indication for FdL abdominoplasty underwent radical liposuction of the abdomen combined with abdominoplasty. The original weight before massive weight reduction ranged between 100 and 168 kg. Average weight reduction was 56.5 kg. The mean BMI was 27.3 kg/m². The average age of our cohort was 40 years. One patient (5 %) had a major complication. This was an infected seroma which could be treated conservatively. Two other patients (10 %) developed an uninfected seroma as a minor complication.

CONCLUSION

Our work shows that lipoabdominoplasty can be performed safely and well even in patients after massive weight loss. It is possible to achieve good body contours without vertical incisions and with a high degree of patient satisfaction. The number of patients who have to undergo FdL abdominoplasty can be successfully reduced by this technique.

The Effect of Hypothyroidism on Surgical Outcomes Postabdominoplasty: A Case-control Study

Hypothyroidism is common in surgical patients. The objective of this study is to determine the rate of short- and long-term complications after abdominoplasty for patients treated for hypothyroidism.

Defining Internal Tissue Closure: High-Resolution Ultrasound Evaluation of Interi-A Novel Internal Tissue Closure System

Background

Seroma remains a leading postsurgical complication in plastic surgery. Conventional drains are ineffective in clearing blood and fluid and closing down surgical spaces. The Interi (Internal Closure System, IC Surgical, Grand Rapids, MI) is comprised of a novel branching internal manifold attached to a self-contained portable pump with a higher, consistent, continuous negative pressure, may reduce this long-standing issue. In addition, high-resolution ultrasound (HRUS) has emerged as an ideal tool to visualize structures, fluid collections, and seromas internally.

Objectives

This study evaluates Interi in full abdominoplasty patients utilizing HRUS to evaluate Interi's ability to evacuate blood and fluid, hold internal tissues together and document, for the first time, what internal tissue healing actually looks like radiographically.

Methods

An IRB approved, Contract Research Organization reviewed retrospective study evaluated consecutive patients undergoing full abdominoplasty utilizing Interi from July 2020 through March 2021 by three plastic surgeons. HRUS visualized and confirmed the presence or absence of fluid collections and healing tissue planes during the postoperative process. Study data and all adverse events were recorded, with HRUS images reviewed by investigators and confirmed by an independent radiologist.

Results

Seventy-one Interi patients were enrolled. Mean age was 43 (range: 21-74) and BMI was 28. Seroma was confirmed clinically and through HRUS in 3/71 patients, and was associated with either clot (2) or failure to activate system (1). Interi's ability to eliminate fluid and approximate/hold surgical tissue planes together was confirmed with HRUS. No other major complications, including abscess, hematomas, or flap necrosis were observed.

Conclusions

This novel Internal Tissue Closure System effectively evacuated blood and fluid, approximated and maintained closure of internal tissue planes in abdominoplasty patients, allowing for primary tissue healing and internal wound closure to occur. Healing tissue planes and any fluid present are easily identified on HRUS visualizing actual internal tissue healing with a simple, widely available radiographic scan.

The Edmonton Obesity Staging System Predicts Postoperative Complications After Abdominoplasty

BACKGROUND

This study investigates the relationship between Edmonton Obesity Staging System (EOSS) and the occurrence of postoperative complications after abdominoplasty in massive weight loss patients.

METHODS

A single-institution retrospective review of patients undergoing abdominoplasty between 2009 and 2019 after massive weight loss. Demographic data, laboratory findings, known risk factors for postoperative complications, as well as data on major and minor complications were extracted from the patient charts. Logistic regression models were used to investigate the relationship between the variables.

RESULTS

Four hundred and five patients were included in the study. The prevalence of EOSS stages was: 0 (no comorbidities, N = 151, 37%), 1 (mild conditions, N = 40, 10%), 2 (moderate conditions, N = 149, 36%) and 3 (severe conditions, N = 70, 17%). Regression analysis showed that, controlling for body mass index (BMI), BMI Δ (maximal BMI - BMI at presentation), bariatric surgery, volume of resected tissue, and duration of surgery, EOSS stage significantly associated with the occurrence of postoperative complications. Compared with EOSS stage 0, EOSS stages 2 and 3 patients were associated with significantly more minor and major complications, respectively. The volume of resected tissue, BMI Δ, and age were associated with the occurrence of major complications. A regression model of comorbidities comprising the EOSS revealed a significant association of variables diabetes mellitus and hypertension with the occurrence of postoperative complications.

CONCLUSIONS

Edmonton Obesity Staging System is a robust predictor of postoperative complications in abdominoplasty.

Abdominoplasty in the Massive Weight Loss Patient: Are Aesthetic Goals and Safety Mutually Exclusive?

Background

The goals of abdominoplasty in massive weight loss (MWL) patients are often functional, with a greater emphasis on safety than on aesthetic rejuvenation. As important as functional improvements and safety are, however, there may be room for increasing the aesthetic potential of abdominoplasties in these patients.

Objectives

To determine the safety of the pursuit of aesthetic goals for abdominoplasty in MWL patients.

Methods

This is a retrospective study examining 910 consecutive female patients consisting of 3 groups: postpartum (n = 718), dietary MWL (n = 65), and bariatric MWL (n = 127). All patients were approached with a well-defined set of aesthetic goals which were pursued as needed and as feasible.

Results

The utilization of aesthetic abdominoplasty components was similar in all groups, supporting the assertion that the groups were subjected to a similar aesthetic emphasis. Logistic regression showed that a history of bariatric MWL was an independent risk factor for multiple complications (odds ratio 2.738, P = 0.014) and that elevated body mass index (BMI), smoking, diabetes, and age were likewise independent risk factors for complications. Propensity score-matched case-control pairs showed that bariatric MWL patients were more likely than dietary MWL patients to experience multiple complications (9.52% vs 0%, P = 0.031).

Conclusions

Bariatric MWL patients but not dietary weight loss patients seem to have a higher risk than postpartum patients. Other comorbidities (elevated BMI, smoking, diabetes, and age) seem to be more important predictors of complications than MWL status. Select MWL patients can likely be approached with an emphasis on aesthetic goals, without increasing risks as compared with the postpartum population.

Post-bariatric Abdominoplasty: Identification of Risk Factors for Complications

PURPOSE

The aim was to evaluate the complication rate after abdominoplasty procedures performed in a high volume post-bariatric center and to identify predictors of complications.

MATERIAL AND METHODS

A retrospective analysis was performed and included all abdominoplasty procedures performed between January 2011 and December 2019. Complications classified according to the Clavien-Dindo classification were documented and potential risk factors were statistically evaluated.

RESULTS

A total of 898 patients were included. Overall complication rate was 29.8%. Type I complications (minor wound problems) occurred in 15.8% (n = 140). Type II complications requiring medical intervention occurred in 10% (n = 90). Five patients had deep venous thrombosis or pulmonary embolism; others received antibiotic treatment for wound infections. In total 42 type III complications occurred in 36 patients, with re-intervention for wound problems (n = 16), seroma (n = 16), umbilical necrosis (n = 4), and bleeding (n = 6). The weight of tissue resected (p < 0.001), the interval between bariatric and body contouring surgery (p < 0.05), preoperative BMI (p < 0.05), male gender (p < 0.05), diabetes mellitus type 2 (p = 0.05), and smoking (p < 0.05) were important predictors for developing complications.

CONCLUSION

In this large retrospective post-bariatric abdominoplasty series, the overall complication rate is low compared to other published series as a consequence of our completely standardized approach and technique. Our analysis shows a significant linear correlation between the amount of skin tissue resected and postoperative complications. Moreover, the longer the interval between bariatric surgery and abdominoplasty, the higher the complication rate. High preoperative BMI, diabetes mellitus type 2, smoking, and male gender were identified as independent significant risk factors for complications.
