Minimising complications in abdominoplasty: An approach based on the root cause analysis and focused preventive steps

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.

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.

The Efficacy of the Transversus Abdominis Plane Block in Abdominoplasty: A Systematic Review and Meta-Analysis

The transversus abdominis plane (TAP) block is a regional abdominal anaesthetic technique frequently used within non-cosmetic abdominal surgery. Its use in cosmetic abdominoplasty procedures is less frequently documented. The literature is devoid of a meta-analysis to quantitatively amalgamate the results of individual reports analysing the efficacy of TAP block compared to alternative analgesic methods in abdominoplasty surgery. The authors aimed to conduct the first meta-analysis within the literature to evaluate this technique's effectiveness in abdominoplasties. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were referred to conduct this systematic review and meta-analysis. All observational and randomised controlled trials (RCTs) comparing the postoperative outcomes of patients who underwent abdominoplasties with TAP blocks versus no TAP blocks were included in this study. The time taken to first analgesia and the amount of analgesia used were the primary outcome measures. The secondary outcome measures include severity of pain, time to mobilisation, and length of stay. Random effect modelling was used for the analysis. The time taken to the first analgesic was significantly lower in the TAP cohort (p <0.05). In addition, there was a lower incidence of postoperative nausea/vomiting(OR 0.18, 95%CI 0.04 - 0.90, p=0.04). Mean total opioid use and operative time were comparable between the TAP and no TAP groups. A qualitative review of the visual analogue scale for pain amongst the included studies showed that it was lower in the TAP group. The authors report the first meta-analysis within the literature showing the efficacy of the TAP block in abdominoplasties. Further high-quality trials are recommended to further the current evidence base.

Predicting lipoabdominoplasty complications with infrared thermography: a delta-R analysis

The diagnosis of the main complications resulting from lipoabdominoplasty has not yet been standardized. Infrared thermal imaging has been used to assess possible complications, such as necrosis and changes in micro- and macro-circulation, based on perforator mapping techniques, among others. The objective of this study was to present two clinical cases involving thermal imaging monitoring of the healing process of lipoabdominoplasty in the immediate postoperative evaluation and its preliminary results. Infrared thermography was performed 24 hours after the operation and on postoperative days 5, 25, and 27. In clinical case 1, it was found that the delta-R (∆TR)-defined as the difference in minimum temperature between the highest and lowest points in the SA3 region (caution suction area) following the classification established by Matarasso-was 0.4°C at 24 hours after surgery and decreased to 0.1°C on a postoperative day 5. There were no complications in this case. In contrast, in clinical case 2, the ∆TR was 1.7°C at 24 hours after surgery (upon hospital discharge) and remained high, at 2.2°C, on postoperative day 5. A higher ∆TR was found in the second patient, who developed necrosis of the surgical wound. The ∆TR thermal index may be a new tool for predicting possible complications, complementing the clinical evaluation and therapeutic decision-making.

Reducing complications in post-bariatric plastic surgery: our experience and literature review

Background: With the rise in obesity, there has been a similar increase in bariatric surgery. This resulted in numerous patients losing significant weight with accompanying circumferential body contouring issues. This has led to an amazing increase in the number of body contouring procedures performed. Methods: The aim of this work is to revise the cases of body contouring in 78 ex-obese patients who underwent body contouring surgery in the Department of Health Life and Environmental Sciences – Plastic Reconstructive and Aesthetic Plastic Surgery Section, from 2007 to 2016. Results: The authors have noticed a deep relationship between adverse events and cigarette smoking and with pre-operative BMI. Regardless of these variables, the authors focused on the protocol for the management of patients, which required a collaboration between medical and nursing staff. Conclusions: Ex-obese patients have an important risk for complications, but the comparison of our personal data with those of the international literature confirms the efficacy of our management protocol with regard to the prevention of complications.

Abdominoplasty after bariatric surgery: comparison of three different techniques

BACKGROUND

Abdominoplasty after massive weight loss is not a cosmetic procedure. The aim of this study was to compare three different techniques for postbariatric abdominoplasty.

METHODS

All postbariatric patients that have undergone abdominoplasty from January 2013 to December 2016 were included in the study. Patients were divided into 3 groups: subjects who underwent standard procedure were allocated ingroup A; those cases performed using a synthetic glue were assigned to group B; cases performed with an energy device were inserted in group C. Operative time, length of stay and complications were recorded.

RESULTS

Seventy-one abdominoplasties were performed in the selected period. Mean operative time was shorter (P<0.01) in group C (94.3±2.7 minutes) than in group A (112.1±16.8 minutes) and in group B (121±13.2 minutes). Mean length of stay was significantly reduced (P<0.01) in group C (2.4±0.7) when compared to group A (3.5±0.6 days) and group B (3.1±0.5 days). Bleeding occurred in 21 (29.5%) patients (15 in group A, 4 in groupB, 3 in group C; P<0.01). Seroma was detected in 22(30.9%) subjects (14 in group A, 2in group B, 6 in group C; P<0.01). Wound dehiscence and umbilical necrosis were recorded in 7 (9.9%) and 9 (12.6%) patients respectively, without statistical differences.

CONCLUSIONS

Both synthetic glue and energy device improve outcomes of postbariatric abdominoplasties. The glue reduces rates of bleeding and seroma. The energy deviceimproves intraoperative hemostasis and shortens operative time.

Is There a Limit? A Risk Assessment Model of Liposuction and Lipoaspirate Volume on Complications in Abdominoplasty

BACKGROUND

Combining liposuction and abdominoplasty is controversial because of concerns for increased complications and potential for vascular compromise of the abdominoplasty flap. Also, the lipoaspirate volume in abdominoplasty is regulated in some areas to as little as 500 ml when performed with abdominoplasty. This study measures abdominoplasty complication rates when performed with and without trunk liposuction, and evaluates the effect of lipoaspirate volume on complications.

METHODS

Abdominoplasty and liposuction of the trunk procedures were identified in the Tracking Operations and Outcomes for Plastic Surgeons database. Multivariate regression models determined the effect of liposuction with abdominoplasty on complications compared with abdominoplasty alone and determined the effect of liposuction volume on complications.

RESULTS

Eleven thousand one hundred ninety-one patients were identified: 9638 (86.1 percent) having abdominoplasty with truncal liposuction and 1553 (13.9 percent) having abdominoplasty alone. Overall complication rates were 10.5 percent and 13.0 percent, respectively. Combined liposuction and abdominoplasty was independently associated with a reduced risk of both overall complications (p = 0.046) and seroma (p = 0.030). Given existing laws limiting liposuction volume to 500 or 1000 ml in combination with abdominoplasty, each of these thresholds was evaluated, with no effect on complications. Surprisingly, increasing liposuction volume was not independently associated with an increased risk of any complication.

CONCLUSIONS

When done by board-certified plastic surgeons, abdominoplasty with truncal liposuction is safe, with fewer complications than abdominoplasty alone. Regulations governing liposuction volumes in abdominoplasty are arbitrary and do not reflect valid thresholds for increased complications.

Can drains be avoided in lipo-abdominoplasty?

Context:

Seroma formation is a common complication after lipoabdominoplasty. Conventionally, drains have been placed to prevent seroma; however, there are problems with drains, namely, pain, compromised mobilisation, breakage, tissue irritation and infection. Strategies to prevent seroma, such as the use of glue or quilting sutures have all been attempted with variable and unpredictable benefit.

Aims:

The author extrapolated the experience with own liposuction protocols to lipoabdominoplasty and began doing away with drains from the year 2006 onwards unless absolutely indicated. Incidence of complications is evaluated here.

Settings and Design:

This retrospective study is the report of our experience with 204 lipoabdominoplasties performed since 2006 upto December 2016.

Subjects and Methods:

Consecutive abdominoplasty patients were evaluated for seroma formation, wound dehiscence till suture removal. Nuances of operative details that helped avoid drains were contemplated.

Results:

Only one patient who had drainless abdominoplasty had seroma formation and wound dehiscence.

Conclusions:

We found that (a) 'toilet liposuction', (a term the author would like to introduce) (b) multilayer wound closure without tension, (c) avoidance of gliding surfaces d) continuous use of pressure garment for 4 days post-operative and (e) reducing the amount of infiltration are the key factors in avoidance of collections and thus seroma formation. If such a technique is diligently followed, desired results are obtained; yet there is no need to insert drains in most patients. Reducing the need of drains permits early ambulation and better patient comfort without seroma and other complications.

The Effect of Body Mass Index on Outcome of Abdominoplasty Operations

BACKGROUND

Increased body mass index (BMI) increase the incidence of seroma formation and wound infection rates and subsequently increases wound dehiscence and ugly scar formation following abdomenoplasty and body contour surgery and also many other aesthetic and plastic surgery. The aim of this study was to determine the effect of BMI on the outcome of abdominoplasty operation.

METHODS

We carried out a prospective study of all patients who underwent abdominoplasty at our institution. Patient were divided into two groups. Group I were subjects with body mass index <30 kg/m² while group II were patients with body mass index >30 kg/m². Demographics and complications (minor and major) were recorded.

RESULTS

Sixty seven patients were enrolled. Group I were 32 patients with a mean age of 35.71 and group II 35 patients with mean age of 36.26 years. Seroma formation, wound complications, prolonged hospital stay and complications were significantly more in group II.

CONCLUSION

We found that increased BMI significantly increased operative time, hospital stay, drainage duration and drainage amount. Our findings showed that obesity alone could increase the incidence of complications and poor outcome of abdominoplasty.

Vulvar Concerns in Women With a History of Abdominoplasty: A Case Series

OBJECTIVES

The aim of the study was to present a series of women with a history of traditional abdominoplasty or circumferential abdominoplasty (belt lipectomy) with vulvar concerns and anatomic changes.

METHODS

We describe 5 women with a history of abdominoplasty who were referred with symptoms of vulvar pain, dyspareunia, lower urinary tract symptoms, and/or lesion/mass. Physical examination revealed elevation of the clitoris on the pubic symphysis with or without retraction of the clitoral hood in each.

RESULTS

Abdominoplasty can result in anatomic changes to the female pubic region after elevation of the mons pubis and consequent elevation of the clitoris with or without retraction of the clitoral hood. Although causation cannot be confirmed from this series, a temporal association of vulvar/clitoral pain, pelvic floor dysfunction, and anatomic alterations with or without lesions after abdominoplasty was present in each case.

CONCLUSIONS

Awareness regarding potential sequelae from anatomic alteration may lead to improved patient counseling and modified surgical techniques to avoid significant elevation of the mons pubis and vulvar commissure.

Does Abdominoplasty Add Morbidity to Incisional Hernia Repair? A Randomized Controlled Trial

Background Abdominoplasty is considered an operation linked to a considerable rate of morbidity. The convenience of simultaneously performing an incisional hernia repair and an abdominoplasty remains controversial. Methods A total of 111 patients were randomized prospectively to compare isolated incisional hernia repair and hernia repair when combined with abdominoplasty. Primary end points were in-hospital stay and early morbidity. Secondary end points were late morbidity, recurrences, and quality of life. Patients were followed-up for 24 months. Results Duration of the surgical procedure differed significantly between both groups (39 vs 85 minutes, P < .001) and postoperative hospital stay (2.5 vs 3.5 days; P < .001). No statistically significant differences in early or late morbidity between both groups were detected. The perceived quality of life for patients was higher in the combined surgery group (P < .001) that in the isolated hernia repair group. Conclusions Postoperative in-hospital stay and early and late morbidity do not differ significantly between isolated incisional hernia repair and simultaneous hernia repair with abdominoplasty, but associated abdominoplasty provides a higher quality of life when indicated.

Combining abdominal and cosmetic breast surgery does not increase short-term complication rates: a comparison of each individual procedure and pretreatment risk stratification tool

BACKGROUND

Combined abdominal and breast surgery presents a convenient and relatively cost-effective approach for accomplishing both procedures.

OBJECTIVES

This study is the largest to date assessing the safety of combined procedures, and it aims to develop a simple pretreatment risk stratification method for patients who desire a combined procedure.

METHODS

All women undergoing abdominoplasty, panniculectomy, augmentation mammaplasty, and/or mastopexy in the TOPS database were identified. Demographics and outcomes for combined procedures were compared to individual procedures using χ(2) and Student's t-tests. Multiple logistic regression provided adjusted odds ratios for the effect of a combined procedure on 30-day complications. Among combined procedures, a logistic regression model determined point values for pretreatment risk factors including diabetes (1 point), age over 53 (1), obesity (2), and 3+ ASA status (3), creating a 7-point pretreatment risk stratification tool.

RESULTS

A total of 58,756 cases met inclusion criteria. Complication rates among combined procedures (9.40%) were greater than those of aesthetic breast surgery (2.66%; P < .001) but did not significantly differ from abdominal procedures (9.75%; P = .530). Nearly 77% of combined cases were classified as low-risk (0 points total) with a 9.78% complication rates. Medium-risk patients (1 to 3 points) had a 16.63% complication rate, and high-risk (4 to 7 points) 38.46%.

CONCLUSIONS

Combining abdominal and breast procedures is safe in the majority of patients and does not increase 30-day complications rates. The risk stratification tool can continue to ensure favorable outcomes for patients who may desire a combined surgery.

Evaluation of abdominal cutaneous sensibility following abdominoplasty

BACKGROUND

Cutaneous hypesthesia is an undesirable postoperative outcome following abdominoplasty. The purpose of this study was to evaluate postabdominoplasty cutaneous sensibility using clinical, quantitative, and reproducible methods.

METHODS

Thirty patients who underwent abdominoplasty were divided into three groups: 0 to 12 months (short-term follow-up), 12 to 24 months (intermediate-term follow-up), and greater than 24 months (long-term follow-up) following abdominoplasty. Abdominal skin was divided into 12 areas, and superficial tactile sensibility was assessed subjectively using a patient questionnaire and objectively using Semmes-Weinstein monofilaments. Statistical analysis was performed using the t test, with significance defined as p ≤ 0.05.

RESULTS

Seventeen patients (56.7 percent) subjectively reported the presence of any abdominal cutaneous sensibility change postoperatively. Of those, 82.4 percent reported indifference toward this outcome. The greatest degree of objective sensibility loss was noted in area 8 (infraumbilical), followed by areas 5 (supraumbilical) and 11 (midline infraincisional). In these areas, there were statistically significant decreases in the average cutaneous pressure thresholds between the short-term and intermediate-term follow-up groups, the intermediate-term and long-term follow-up groups, and the short-term and long-term follow-up groups.

CONCLUSIONS

Postabdominoplasty cutaneous sensibility losses improve over time. These findings may enable plastic surgeons to better inform their patients regarding the risk of sensibility loss and the longitudinal outcome of such changes postoperatively.
