Evidence-Based Abdominoplasty Review With Body Contouring Algorithm

Analysis of factors affecting the postoperative drainage in patients with abdominoplasty with circumferential liposuction

Background

Abdominoplasty combined with circumferential liposuction serves as a reliable and indispensable method for aesthetic body contour. This study aims to investigate the factors that influence drainage volume and duration after the procedure.

Methods

A retrospective study of 89 patients who received abdominoplasty with circumferential liposuction between January 2021 and October 2024 was conducted. Total drainage volume and duration were recorded. Univariable and multivariable linear regression and correlation analyses were utilized to identify the correlation between postoperative drainage and patient-related, and operation-related variables.

Results

The mean total drainage volume was 420.6 ± 220.8 ml, and the mean drainage duration was 6.8 ± 1.9 days. Based on the univariate and multivariate linear regression analysis, several statistically significant associations were identified. BMI (p = 0.001), volume of lipoaspirate (p = 0.001), and weight of resected tissue (p < 0.001) were significantly associated with the drainage volume. BMI (p < 0.001), operation time (p < 0.001), volume of lipoaspirate (p < 0.001), and weight of resected tissue (p = 0.01) were risk factors influencing drainage duration.

Conclusions

BMI, volume of lipoaspirate, and weight of resected tissue were associated with drainage volume and duration. Operation time was an independent factor influencing drainage duration.

The Impact of Diabetes on Abdominoplasty Outcomes: A Systematic Review and Meta-Analysis

BACKGROUND

Abdominoplasty is increasingly sought after by patients for aesthetic rejuvenation or functional improvement. However, no previous study has comprehensively evaluated the impact of diabetes on post-abdominoplasty complications. This systematic review aimed to investigate the impact of diabetes on outcomes following abdominoplasty.

METHODS

A comprehensive literature search was conducted systematically on MEDLINE Ovid, PubMed, Web of Science, and the Cochrane CENTRAL databases from inception to January 2023. The primary outcomes of interest were overall complications. The secondary outcomes included major complications and minor complications. A meta-analysis was performed in accordance with PRISMA guidelines to examine the impact of diabetes on post-abdominoplasty complications.

RESULTS

A total of fifteen studies involving 79724 patients, 5483 of whom had diabetes, met our inclusion criteria. Patients with diabetes were more likely to suffer from overall complications (OR = 1.63, 95% CI, 1.12-2.14; P < 0.05), major complications (OR = 1.44, 95% CI, 1.24-1.64; P < 0.05) and minor complications (OR = 1.84, 95% CI, 1.34-2.34; P < 0.05) than non-diabetic patients after abdominoplasty. Furthermore, patients with diabetes had a higher risk of wound-related complications (OR = 2.54, 95% CI, 1.80-3.27; P < 0.05) than non-diabetic patients after abdominoplasty.

CONCLUSIONS

This study is the first systematic review and meta-analysis to evaluate how diabetes affects abdominoplasty outcomes. It finds that diabetes significantly increases the risk of overall, major, minor, and wound-related complications compared to non-diabetic patients. However, it does not elevate the risk of ischemic complications. Surgeons should inform patients about these risks, and future research should investigate how glycemic control might reduce these complications.

Does Seven Days of Postoperative Enoxaparin Increase Bleeding Risk in Abdominal Contouring Surgery? A Single-center Experience

Background

Venous thromboembolism (VTE) poses a major risk after abdominal contouring surgery, impacting morbidity and mortality. Despite various preventative strategies, surgeons are cautious about using enoxaparin for extended postoperative periods. This study aims to determine if a 7-day postoperative course of enoxaparin increases bleeding risks compared with a single dose of intraoperative unfractionated heparin in patients undergoing abdominal contouring surgery.

Methods

A retrospective cohort analysis was performed on patients who underwent abdominoplasty or panniculectomy from August 2017 to October 2023. Patients were split into 2 groups: Group 1 received 5000 units of intraoperative unfractionated heparin in addition to 7 days of postoperative enoxaparin (40 mg daily); group 2 received only the intraoperative heparin dose. Primary outcomes included bleeding events and VTE incidence. Secondary outcomes were seroma, infection, surgical site dehiscence, necrosis, drain duration, and reoperation rates.

Results

The study included 121 patients (111 women, 10 men), with 61 patients in group 1 and 60 in group 2. The average age was 49 ± 12 years, and the average body mass index was 29.8 ± 5 kg/m². No cases of VTE were reported. Postoperative bleeding occurred in 3 patients (4.9%) in group I and 2 patients (3.3%) in group 2, showing no statistically significant difference (P = 0.66). Secondary outcomes also showed no significant differences between the groups.

Conclusions

Our study of 121 patients undergoing either abdominoplasty or panniculectomy demonstrated that administering enoxaparin for 7 days postoperatively is safe and does not increase the risk of bleeding.

Health-Related Quality-of-Life Effects of Rectus Repair during Body Contouring Surgery in Postbariatric Patients: A Prospective Study

BACKGROUND

Massive weight loss after bariatric surgery often leads to psychological and physical dissatisfaction, resulting in an increased demand for body contouring surgery (BCS). As a result of these operations, health-related quality of life (HRQL) is improved. However, little is known about the impact of rectus plication during BCS on HRQL.

METHODS

This multicenter prospective cohort study included postbariatric primary BCS patients with a minimum follow-up period of 12 months between January of 2016 and December of 2019. Patients were divided into 2 groups based on plication status. Using the BODY-Q, a patient-reported outcome measure, HRQL was measured preoperatively and at least 12 months postoperatively. Six HRQL domains were investigated: body image, physical function, psychological function, sexual function, social function, and physical symptoms.

RESULTS

A total of 305 patients were included in this study: 201 of these patients (66%) did not undergo plication, whereas 104 patients (34%) did. HRQL improved significantly 12 months after BCS in all measured domains, regardless of plication status. Delta scores were significantly higher in the plication group in all HRQL domains. After adjusting for baseline score and other significant variables through multivariate linear regression, 3 scales remained significant: body image ( P = 0.001), psychological function ( P = 0.035), and sexual function ( P = 0.035).

CONCLUSIONS

Three of 6 HRQL domains showed significant improvement after BCS with rectus plication, predominantly body image. Preoperative counseling and surgical planning could benefit from this information. The long-term effects of rectus plication on HRQL should be explored in future research.

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.

Effect of Compression Garments on Post-Abdominoplasty Outcomes: A systematic Review of the current Evidence

Introduction

It is commonly believed that using abdominal binders or compression garments (CGs) after an abdominoplasty could encourage fluid to drain, which would prevent fluid from building up at the surgical site and reduce the risk of seroma and other similar problems.

Objective

To evaluate the effect of the use of abdominal binders or CG on the post-operative outcomes following abdominoplasty.

Design

Systematic review.

Method

Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines were followed to select relevant studies from 2004 to 2024. Data from the included studies were extracted to assess the quality and risk of bias using a modified Jadaad score.

Main outcome

Post-operative seroma formation.

Secondary outcome

Ventilatory function, intra-abdominal pressure (IAP), and subcutaneous edema were the outcomes of interest.

Results

Only 5 trials totaling 130 patients were included in this review. Utilizing post-operative CG following abdominoplasty showed a non-significant tendency to decrease seroma development, ventilatory function, and subcutaneous edema. The limited evidence available also suggested that using post-operative CG increases IAP.

Conclusion

Weak evidence supports the beneficial use of abdominal binders following abdominoplasty.

Limitations

Low-quality scientific evidence available from the scant data and low caliber of the literature support the use of CG post-abdominoplasty. Therefore, unified outcome reporting and rigid randomized clinical trials are necessary to obtain valid data.

Direct Subscarpal Lipectomy Combined With Liposuction in Abdominoplasty: An Analysis of Safety and Efficacy in 200 Consecutive Patients

BACKGROUND

Abdominoplasty procedures continue to evolve because combining techniques such as suction-assisted lipectomy or direct subscarpal lipectomy have proven to be powerful adjuncts to achieve optimal aesthetic results. However, concern has been expressed about combining techniques simultaneously given the potential to damage the vascularity of the abdominoplasty flap.

OBJECTIVES

The aim of this study was to assess the safety and efficacy of simultaneous direct subscarpal lipectomy combined with liposuction in abdominoplasty patients.

METHODS

A 4-year retrospective review of consecutive abdominoplasties (n = 200) performed by a single surgeon was conducted. Liposuction of the abdominal flap and flanks was performed in all patients. After raising the abdominoplasty flap, undermining was performed to just beyond the xyphoid, the lower rib margins superiorly, and the anterior axillary line laterally. Fat deep to Scarpa's fascia was then removed by direct tangential excision in all zones of the abdominal flap.

RESULTS

The patients had a mean age of 42.19 years and BMI of 28.10 kg/m2; the mean follow-up time was 7 months. Seroma occurred in 13 patients (6.5%), superficial wound dehiscence treated with local wound care in 16 patients (8%), hypertrophic scarring in 16 patients (8%), partial umbilical necrosis in 1 patient (0.5%), and partial umbilical epidermolysis in 6 patients (3%). No patients experienced major or minor full-thickness tissue loss. No patients needed reoperation.

CONCLUSIONS

Simultaneous direct excision of subscarpal fat with liposuction of the abdomen and flanks does not appear to subject any zone of the abdominoplasty flap to increased risks of vascular compromise. No flap necroses were observed. The technique described is safe and may provide superior abdominoplasty results.

Exploring the Potential of ChatGPT-4 in Responding to Common Questions About Abdominoplasty: An AI-Based Case Study of a Plastic Surgery Consultation

BACKGROUND

With the increasing integration of artificial intelligence (AI) in health care, AI chatbots like ChatGPT-4 are being used to deliver health information.

OBJECTIVES

This study aimed to assess the capability of ChatGPT-4 in answering common questions related to abdominoplasty, evaluating its potential as an adjunctive tool in patient education and preoperative consultation.

METHODS

A variety of common questions about abdominoplasty were submitted to ChatGPT-4. These questions were sourced from a question list provided by the American Society of Plastic Surgery to ensure their relevance and comprehensiveness. An experienced plastic surgeon meticulously evaluated the responses generated by ChatGPT-4 in terms of informational depth, response articulation, and competency to determine the proficiency of the AI in providing patient-centered information.

RESULTS

The study showed that ChatGPT-4 can give clear answers, making it useful for answering common queries. However, it struggled with personalized advice and sometimes provided incorrect or outdated references. Overall, ChatGPT-4 can effectively share abdominoplasty information, which may help patients better understand the procedure. Despite these positive findings, the AI needs more refinement, especially in providing personalized and accurate information, to fully meet patient education needs in plastic surgery.

CONCLUSIONS

Although ChatGPT-4 shows promise as a resource for patient education, continuous improvements and rigorous checks are essential for its beneficial integration into healthcare settings. The study emphasizes the need for further research, particularly focused on improving the personalization and accuracy of AI responses.

Aesthetic Improvement of Body Proportion Through Trunk Liposculpture: A Waistline-based Strategy

BACKGROUND

Abdominal contouring through liposuction has been practiced for decades. However, few studies have focused on describing the definition and enhancement of the waistline in torso contouring procedures.

OBJECTIVES

In the present study, the authors proposed a waistline-based strategy for abdominal liposculpture to achieve a better aesthetic outcome and emphasize high overall patient satisfaction.

METHODS

The data of patients who underwent the waistline-based liposculpture procedure from 2020 to 2023 were retrospectively reviewed. Aesthetic improvement of the central trunk contour was evaluated and analyzed by comparing preoperative and postoperative photogrammetric measurements. Satisfaction with the outcome was assessed with a patient satisfaction questionnaire.

RESULTS

A total of 70 patients were enrolled in this study. During 6 months of postoperative evaluation, the shape of the central trunk contour improved significantly (both waist concavity and hip convexity increased quantitatively, P < .05), while the position of the waist did not differ significantly postoperatively (P > .05). All patients were satisfied with their postoperative outcomes, including their overall aesthetic appearance, waistline position, and waist-to-hip ratio. There were no intraoperative complications or rare postoperative complications.

CONCLUSIONS

Waistline-based liposculpture is a simple and effective procedure to improve the aesthetic outcomes of trunk contouring and has highly satisfactory results after long-term follow-up.

Secondary Body Contouring

Body contouring surgeries, common yet intricate owing to unique patient characteristics, often necessitate revisions or secondary procedures. Balancing patient expectations and surgical limitations while methodically addressing shortcomings is crucial. This article aims to provide an extensive understanding of managing such complex cases, thus enhancing the reader's approach to secondary body contouring surgeries.

Clinical Practice Patterns in Abdominoplasty: 16-Year Analysis of Continuous Certification Data from the American Board of Plastic Surgery

BACKGROUND

The authors evaluated trends in practice patterns for abdominoplasty based on a 16-year review of tracer data collected by the American Board of Plastic Surgery as part of the continuous certification process.

METHODS

To facilitate comparison of an equal number of patients over time, tracer data from 2005 to 2021 were split into an early cohort (EC) (from 2005 to 2014) and a recent cohort (RC) (from 2015 to 2021). Fisher exact tests and two-sample t tests were used to compare patient demographics, surgical techniques, and complication rates.

RESULTS

Data from 8990 abdominoplasties (EC, n = 4740; RC, n = 4250) were analyzed. RC abdominoplasties report a lower rate of complications (RC, 19%; EC, 22%; P < 0.001) and a lower rate of revision surgery (RC 8%; EC, 10%; P < 0.001). This has occurred despite the increased use of abdominal flap liposuction (RC, 25%; EC, 18%; P < 0.001). There has been a decline in the use of wide undermining (81% versus 75%; P < 0.001), vertical plication of the abdomen (89% versus 86%; P < 0.001), and surgical drains (93% versus 89%; P < 0.001). Abdominoplasty surgery is increasingly performed in an outpatient setting, with increased use of chemoprophylaxis for thrombosis prevention.

CONCLUSIONS

Analysis of these American Board of Plastic Surgery tracer data highlights important trends in clinical practice over the past 16 years. Abdominoplasty continues to be a safe and effective procedure with similar complication and revision rates over the 16-year period.

Clinical Evaluation of 310 Abdominoplasties and Measurement of Scar Level

BACKGROUND

Most published studies on abdominoplasty focus on methods to reduce the risk of seromas. These methods include limited dissection (lipoabdominoplasty), quilting sutures, and preservation of the Scarpa fascia. Quantitative evaluation of the aesthetic result has been lacking.

METHODS

A retrospective study was undertaken of all patients undergoing abdominoplasty in the author's practice from 2016 to 2022. A full abdominoplasty was performed, usually with liposuction (87%). All patients were treated under total intravenous anesthesia without paralysis or prone positioning. A single closed suction drain was removed 3 or 4 days after surgery. All procedures were performed as outpatients. Ultrasound surveillance was used to detect any deep venous thromboses. No patient received chemoprophylaxis. The operating table was flexed, often to 90°. Deep fascial anchoring sutures were used to attach the Scarpa fascia of the flap to the deep muscle fascia. Measurements of the scar level were made at intervals after surgery up to 1 year.

RESULTS

Three hundred ten patients were evaluated, including 300 women. The mean follow-up time was 1 year. The overall complication rate, which included minor scar deformities, was 35.8%. Five deep venous thromboses were detected. There were no hematomas. Fifteen patients (4.8%) developed seromas that were successfully treated by aspiration. The mean vertical scar level 1 month after surgery was 9.9 cm (range, 6.1-12.9 cm). There was no significant change in scar level at subsequent follow-up times up to 1 year. By comparison, the scar level in published studies ranged from 8.6 to 14.1 cm.

DISCUSSION

Avoidance of electrodissection reduces tissue trauma that causes seromas. Flexed patient positioning during surgery and deep fascial anchoring sutures are effective in keeping the scar low. By avoiding chemoprophylaxis, hematomas can be avoided. Limiting the dissection (lipoabdominoplasty), preserving the Scarpa fascia, and adding quilting (progressive tension) sutures are unnecessary.

CONCLUSIONS

Total intravenous anesthesia offers important safety advantages. Avoiding electrodissection is effective in keeping seroma rates at a tolerable level (5%), and the scar low and more easily concealed. Alternative methods present disadvantages that may contribute to a suboptimal aesthetic result and require additional operating time.

Scarpa Fascia Preservation to Reduce Seroma Rate on Massive Weight Loss Patients Undergoing Abdominoplasty: A Comparative Study

(1) Background: An increasing number of patients undergo bariatric surgery and seek body contouring surgery after massive weight loss (MWL). Abdominoplasty itself is associated with a high complication rate in these patients, particularly due to seroma formation. Scarpa fascia preservation (SFP) has been proven to be an efficient method of reducing seroma rates. We aimed to evaluate the possible benefits of SFP on massive weight loss patients comparatively. (2) Methods: This is a single-center retrospective comparative study encompassing 202 MWL patients operated between 2009 and 2019 at Turku University Hospital. Patients included in the study had a preoperative weight loss greater than 30 kg. Of them, 149 went through traditional abdominoplasty and 53 abdominoplasties with SFP. The primary outcome measure was seroma occurrence, while secondary outcomes included drainage amount, hospital stay, surgical site occurrence, and need for blood transfusion. (3) Results: The only statistically significant difference between groups on patients' demographics was the sex ratio, favoring females in the control group (43:10, 81% vs. 130:19, 87%, p = 0.018). SFP significantly reduced seroma occurrence (9.4% vs. 26.2%, p = 0.011) and decreased mean drainage duration (3.7 ± 2.4 vs. 5.3 ± 3.2 days, p = 0.025). There was a trend towards lower drainage output (214.1 ± 162.2 mL vs. 341.9 ± 480.5 mL, p = 0.060) and fewer postoperative days on ward in the SFP group. Other complication incidences did not differ between the groups. The multivariable analysis did not show any significant factor for seroma formation or surgical site occurrence. (4) Conclusions: Preserving Scarpa fascia on MWL patients may result in decreased seroma occurrence and a shorter time to drain removal.

Care of the Patient After Metabolic and Bariatric Surgery

Weight loss surgery, also known as metabolic and bariatric surgery (MBS), is an effective weight loss treatment and is associated with reduced mortality and improvements in obesity-related health conditions and quality of life. Postsurgical anatomical and physiologic changes include decreased absorption of micronutrients and alterations in gut-brain hormonal regulation that affect many aspects of health. Patients require ongoing monitoring of their physical and mental health for lasting success. Internists, particularly primary care clinicians, are in an ideal position to monitor for nonserious complications in the short and long term, adjust management of chronic diseases accordingly, and monitor for mental health changes. This article reviews key issues that internists should be aware of for supporting patients' health in the short and long term after MBS.

CURRENT PRINCIPLES OF TREATING ABDOMINAL COMPLICATIONS

Abdominal plastic is one of the most common operations in the field of plastic surgery. The main goal of abdominal plastic is to improve the body contours in the area of the anterior abdominal wall, by excising excessive skin and fat tissues, suturing diastasis of the direct abdominal muscles. Although abdominal plastic is considered a safe surgery with a high level of positive outcomes, there are still various kinds of complications, the treatment of which requires the use of modern methods. The work is based on the analysis of literature data on abdominal plastic and analysis of the postoperative period of 172 patients operated on in plastic surgery clinics in Krasnoyarsk from 2017 to 2020. Statistical data on abdominal plastic prevalence among aesthetic procedures were analyzed. Based on the identified data, it is shown that various types of abdominal plastic are quite in demand, which dictates the need to study possible complications after surgery, and modern methods of treating complications. The article analyzes common types of complica­tions after abdominal plastics and describes the algorithms for treating these complications. A comparative analysis of the incidence of complications in plastic surgery clinics in Krasnoyarsk was carried out with data from European plastic surgery clinics. Complications after abdominal plastic vary in severity and in the effect they have on aesthetic outcomes. Most complications can be treated in an outpatient setting, following modern standards, with satisfactory results.

Aesthetic and Functional Abdominoplasty: Anatomical and Clinical Classification based on a 12-year Retrospective Study

Abdomen reshaping is a common plastic surgery procedure, and numerous surgical techniques have been described in the scientific literature. To standardize surgical approach, we propose our protocol that correlates patients' anatomy with the type of procedure performed.

Methods

Between 2008 and 2020, we retrospectively analyzed 582 consecutive female patients who underwent abdomen reshaping procedures, assessing anatomical features, complication rate, patient satisfaction, and surgical result, comparing them with previous reports in the literature. Aesthetic outcomes were evaluated with VAS scale (0-10).

Results

Among the 582 patients recruited in the study, we performed 74 liposuctions as a single procedure, 62 mini-abdominoplasties, 28 T-inverted abdominoplasties, and 418 full-abdominoplasties. Aesthetic outcome evaluation reported a mean value of 8.2 from patients and 7.8 from surgeons. We experienced four early postoperative bleedings requiring hemostasis revision, 18 wound dehiscences, five seromas, and 24 re-interventions for aesthetic issues. We found no differences in the complication rate while comparing our data with previous reports in the literature.

Conclusions

Our protocol and surgical technique have proved to be effective, safe, and reproducible, with high patient and surgeon satisfaction, low complication rate, and fast recovery time.

The Global Prevalence of Seroma After Abdominoplasty: A Systematic Review and Meta-Analysis

BACKGROUND

Abdominoplasty is one of the most common cosmetic surgeries performed worldwide. Seroma is also the most common local complication associated with abdominoplasty, which increases care costs, reduces patient satisfaction, and has serious complications for patients. Results of previous studies report different levels of seroma prevalence after abdominoplasty. The aim of this study is to standardize the statistics of the prevalence of seroma after abdominoplasty using meta-analysis.

METHODS

In this systematic review and meta-analysis study, data from studies conducted on the global prevalence of seroma after abdominoplasty was extracted using the keywords "Prevalence, Epidemiology, Complications, Abdominoplasty, Seroma, and Lipo abdominoplasty" in the databases of Science, Scientific Information Database, MagIran, Embase, Scopus, PubMed, Web of Science, and Google Scholar search engine without time limit until October 2020. The random-effects model was used to analyze the eligible studies, and the heterogeneity of the studies was investigated with the I² index. Data analysis was performed using Comprehensive Meta-Analysis software (Version 2).

RESULTS

In reviewing 143 studies (five studies related to Asia, 55 studies related to Europe, three studies related to Africa, and 80 studies related to the Americas) with a total sample size of 27834 individuals, the global prevalence of seroma after abdominoplasty was obtained as 10.9% (95% CI: 9.3-3.6.6%) and the highest prevalence of seroma was related to the Europe continent with 12.8% (95% CI: 10.15-3.9%). The results from meta-regression showed a declining trend in the global prevalence of seroma after abdominoplasty with an increase in the sample size, age of study participants, and the year of study (p < 0.05).

CONCLUSIONS

This study shows that the prevalence of seroma after abdominoplasty is high globally. Therefore, physicians and specialists must consider its importance and take the controlling and treatment measures seriously.

Dissection Technique for Abdominoplasty With Scarpa Fascia Preservation: Comparative Study on Avulsion Technique Versus Diathermocoagulation

BACKGROUND

Many strategies have been developed to lower the high complication rate associated with a full abdominoplasty. The dissection technique may have a role to achieve this goal.

OBJECTIVES

The present study compared 2 different dissection techniques to perform a full abdominoplasty with Scarpa fascia preservation: avulsion technique and electrodissection.

METHODS

A retrospective observational cohort study was performed in 2 health institutions from January 2005 to January 2019. A total of 251 patients were involved: 122 patients submitted to abdominoplasty employing the avulsion technique (Group A) and 129 with diathermocoagulation (coagulation mode) (Group B). The latter was further divided into group B1 (57 patients with device settings according to surgeon's preferences) and B2 (72 patients with a specific regulation aiming at minimal tissue damage). Several variables were analyzed: population characteristics, time of hospital stay, time to drain removal, total and daily drain output, emergency department visits, readmission, reoperation, and local and systemic complications.

RESULTS

The general characteristics of both groups did not statistically significantly differ except for previous abdominal surgery. The diathermocoagulation group had a significantly lower length of hospital stay and time to drain removal. Moreover, these advantages were maximized when electrocautery was conducted with a specific low-voltage setting as significant differences were found. The other outcomes were identical.

CONCLUSIONS

Limiting the extension of electrodissection with the avulsion technique did not present any advantage. Utilizing diathermocoagulation (coagulation mode) during a full abdominoplasty with Scarpa fascia preservation, especially when it is aimed at minimal tissue damage, reduces patients' time with drains.

TULUA Lipoabdominoplasty: No Supraumbilical Elevation Combined With Transverse Infraumbilical Plication, Video Description, and Experience With 164 Patients

BACKGROUND

TULUA (transverse plication, undermining halted at umbilicus, liposuction [without restrictions], umbilicoplasty with a skin graft, and abdominoplasty with low transverse scar localization) is a fundamentally different lipoabdominoplasty technique intended to reduce the risk of vascular compromise, correct wall laxity through a unique plication, allow freedom in choosing the umbilical position, reduce tension on closure, and keep the final scar low.

OBJECTIVES

The objectives of this article were to describe the TULUA technique and its variations, delineate the indications and contraindications, show the expected results, and determine its safety profile.

METHODS

A series of 164 patients is presented. The technique's basic tenets were (1) infraumbilical wide transverse plication; (2) no undermining above the umbilicus; (3) unrestricted liposuction, including the supraumbilical tissues; (4) umbilical amputation and neoumbilicoplasty in the ideal position with a skin graft; and (5) low transverse scar placement. Complications were recorded and tabulated. Results were evaluated utilizing Salles' and the author's graded scales.

RESULTS

Scores averaged 9.4 out of 10 on the Salles' scale and 5.6 out of 6 on the author's scale, demonstrating adequate correction of the abdominal contour and the wall and skin laxity, with properly placed scars and umbilici, and without compensatory epigastric bulging. Overall, 20% of the patients experienced a complication: 9.7% experienced a delay in either the healing or graft take of the umbilicus, 0.6% developed skin necrosis, 0.6% experienced a wound dehiscence, 2.4% had an infection, and 4.9% developed a seroma.

CONCLUSIONS

The TULUA lipoabdominoplasty technique was found to improve abdominal wall laxity and aesthetics to a degree that is similar to traditional abdominoplasty, based on the evaluated parameters. The complications associated with the procedure are within the range of other abdominoplasty techniques, and the technique potentially has a reasonable safety profile with less risk of vascular compromise.

Pregnancy after transverse plication lipoabdominoplasty, undermining halted at umbilicus, liposuction without restrictions, umbilicoplasty with a skin graft, and low transverse scar localization (TULUA). Literature review and case report

OBJECTIVE

To report the case of a pregnant woman with a history of transverse plication abdominoplasty (TULUA) and to conduct a review of the available literature on the impact of this intervention on the course of gestation and vice versa.

METHODS

Case report of a 23-year-old pregnant woman with a history of TULUA abdominoplasty performed eight months before pregnancy. A literature search was conducted in Medline, Cochrane Library, SciELO, LILACS, BVS and Google Scholar, with no restriction by language or date of publication. Studies of any design were included, including case reports. Book chapters and clinical practice guidelines were excluded.

RESULTS

Overall, 1,158 studies were identified, of which 13 case reports or case series met the inclusion and exclusion criteria, for a total of 111 patients. No reports of TULUA before pregnancy were found. Age at the time of delivery ranged between 19 and 37 years and all births were at term, with newborns of adequate birth weight. Eleven studies described the route of delivery, including 7 cases of cesarean section and 4 vaginal deliveries. Two studies described the development of cervical prolapse, one at 15 weeks of gestation and the second at the time of labor. Three patients experienced impaired abdominal wall nerve block during the cesarean section. Regarding cosmetic results after delivery, there is a paucity of data about potential relapse in the form of skin laxity or diastasis. However, satisfactory cosmetic results were reported in two cases.

CONCLUSIONS

There is a paucity of literature on the topic of pregnancy following abdominoplasty, and it is limited to case reports. The literature suggests that abdominoplasty could increase the frequency of cervical prolapse and cesarean section, although the impact on perinatal outcome is not clear. It appears that abdominal wall repair is maintained. Additional studies focusing on perinatal outcomes in women with abdominoplasty and the impact of gestation on the results of the intervention are required.

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

BACKGROUND

Post-bariatric patients present a surgical challenge within abdominoplasty because of residual obesity and major comorbidities. In this study, we analyzed complications following abdominoplasty in post-bariatric patients and evaluated potential risk factors associated with these complications.

OBJECTIVES

The authors sought to determine the complications and risk factors following abdominoplasty in post-bariatric patients.

METHODS

A retrospective study of patients who underwent abdominoplasty was performed from January 2009 to December 2018 at our institution. Variables analyzed were sex, age, body mass index (BMI), smoking, surgical technique, operative time, resection weight, drain output, and complications.

RESULTS

A total of 406 patients were included in this study (320 female and 86 male) with a mean age of 44.4 years and a BMI of 30.6 kg/m2. Abdominoplasty techniques consisted of traditional (64.3%), fleur-de-lis technique (27.3%), and panniculectomy without umbilical displacement (8.4%). Overall complications recorded were 41.9%, the majority of these being wound-healing problems (32%). Minor and major complications were found in 29.1% and 12.8% of patients, respectively. A BMI value of ≥30 kg/m2 was associated with an increased risk for wound-healing problems (P = 0.001). The frequency of total complications was significantly related to age (P = 0.007), BMI (P = 0.004), and resection weight (P = 0.001). Abdominoplasty technique tended to influence total complications.

CONCLUSIONS

This study demonstrates in a fairly large sample of post-bariatric patients (n = 406) that abdominoplasty alone can be performed safely, with an acceptable complication rate. Age, BMI, and resection weight are shown to be significant risk factors for total complications. The role of surgical technique needs to be evaluated further.

Local anesthetic pain catheters to reduce opioid use in massive weight loss patients undergoing abdominoplasty: A comparative study

BACKGROUND

Abdominoplasty is a common procedure for anatomical restoration of the lower abdominal skin, with a continuously increasing annual number of procedures performed. The significance of postoperative pain management is of crucial importance from a patient's perspective and to ensure the achievement of the aimed clinical outcome. We evaluated the efficacy of local pain pump catheters (PPCs) on massive weight loss patients undergoing body-contouring abdominoplasty.

METHODS

Primary abdominoplasty procedures after massive weight loss performed from 2009 to 2014 were retrospectively reviewed. The patients were divided into two groups according to the use of the PPC. The primary outcome measure was the amount of opioid use calculated as morphine equivalents. The secondary outcome measures were the length of hospital stay (LOS) and early postoperative complications within 30 days of surgery.

RESULTS

A total of 61 patients were included in the study: 24 patients in the PPC group and 37 patients in the conventional abdominoplasty analgesia (CAA) group. No significant differences between the study groups were found with regard to demographics, operative time, and resection weight. A significantly decreased use of opioids was observed after using PPC versus control (14.0 ± 13.9 mg vs. 74.6 ± 73.3 mg, p < 0.001). Similarly, the LOS was shorter in the PPC group (3.1 ± 1.1 days vs. 3.8 ± 1.0 days, p = 0.023). There was a similar rate of complications in both groups (45.8% vs. 40.5%, p = 0.622). The most common complication was seroma formation (25.0% vs. 18.5%, p = 0.315).

CONCLUSION

The use of local anesthetic pain catheters in abdominoplasty may be associated with a decreased use of opioids and might result in a shorter hospital stay on massive weight loss patients. Further studies are needed to validate this treatment modality.
