Abdominoplasty in the Overweight and Obese Population: Outcomes and Patient Satisfaction

Impact of Body Mass Index on Outcomes of Patients Undergoing Liposculpture in Private Practice

Background

The popularity of liposculpture has increased due to the high patient satisfaction rate and low number of complications. However, in Latin America, serious complications have been reported due to various factors. Therefore, our objective was to determine the association of a BMI of 30 kg/m2 or more with the development of postoperative complications in patients undergoing liposculpture.

Methods

A retrospective cohort study was performed in patients undergoing liposculpture at the Clinica Nova Quirurgica in Arequipa between 2020 and 2021.

Results

A total of 231 patients were identified. The median age was 35 years, the majority of patients were women (97.4%), and 25.6% of patients had a BMI of 30 kg/m2 or more. Postoperative complications developed in 13.4%, the majority being seromas (10.8%), followed by superficial site infections (2.6%), hematomas (1.7%), asymmetry (1.7%), and deep vein thrombosis (0.4%). No other complications were identified. In the multivariable analysis, risk factors for the development of complications were a BMI of 30 kg/m2 or more [relative risk (RR) = 3.63; 95% confidence interval (CI), 1.27-10.32; P = 0.016], longer operative time (RR = 1.01; 95% CI, 1.00-1.02; P = 0.001), and greater volume of fat removed (RR = 1.01; 95% CI, 1.01-1.01; P = 0.002).

Conclusions

Patients with a BMI of 30 kg/m2 or more undergoing liposculpture have a ~3.5-fold higher risk of developing postsurgical complications compared with patients without obesity. Other risk factors were longer operative time and greater volume of fat removed. Adequate patient selection is crucial to obtain optimal results.

The impact of physical activity on patient-reported outcomes following deep inferior epigastric perforator flap breast reconstruction

INTRODUCTION

Although higher preoperative physical activity levels have been shown to be beneficial to postoperative recovery at large, their effect on patient-reported outcomes after deep inferior epigastric perforator (DIEP) flap breast reconstruction has yet to be investigated. This study aimed to correlate patient physical activity levels with patient-reported outcome measures.

METHODS

A prospectively maintained database of patients who underwent DIEP flap breast reconstruction between July 2021 and June 2022 was analysed. Physical activity levels were assessed using the Global Physical Activity Questionnaire (GPAQ) and patient-reported outcomes were measured using the BREAST-Q questionnaire, both preoperatively and 1 year postoperatively. Patients were stratified into low (<1000 METs) and high (>1000 METs) physical activity groups.

RESULTS

Of the 136 patients who underwent surgery, 51 completed both questionnaires, with 34 responses meeting completeness criteria for statistical analysis. The low-MET group (n = 19) and high-MET group (n = 15) were comparable in age and comorbidities. Postoperatively, the low-MET group exhibited a 54% increase in physical activity levels, whereas the high-MET group showed a 17% decrease (p < 0.01). The low-MET group experienced significant declines in psychosocial well-being (9.3%, p = 0.04) and sexual well-being (14%, p = 0.02), whereas the high-MET group did not show significant changes in these domains. Satisfaction with the unclothed abdomen increased significantly in the low-MET group (2.9 from 2, p = 0.001), while the high-MET group showed a nonsignificant decrease (3.2 from 2.9, p = 0.43). However, abdominal well-being significantly decreased in both groups, with a 56% decline in the high-MET group (p = 0.006) and a 51% decline in the low-MET group (p = 0.0002). The latter reflects the perceived difference between aesthetic appearance and well-being.

CONCLUSIONS

Patients with lower preoperative physical activity levels showed improved activity postsurgery, potentially due to motivational factors from the reconstructive process. Conversely, those with higher preoperative activity levels faced greater challenges in maintaining their activity levels postsurgery, potentially arising from disruptions in daily routines and donor site symptoms, indicating a need for targeted interventions to support this group. Concurrently, patients with higher baseline exercise levels did not show a decrease in psychosocial and sexual well-being, possibly reflecting a higher resilience to the operative process. These findings underscore the importance of integrating physical activity assessments into preoperative evaluations to inform patient-centred care and optimise recovery outcomes.

A Systematic Review of Questionnaires Assessing Patient Satisfaction in Plastic Surgery: Tools, Topics, and Surgical Types

Background

Patient satisfaction is crucial for evaluating healthcare services, including plastic surgery. This systematic review aims to analyze questionnaires assessing patient satisfaction in plastic surgery, identifying their strengths and weaknesses to improve outcomes and enhance the quality of care.

Methods

A comprehensive literature search was conducted using electronic databases. Studies were included if they were original research articles, written in English, and focused on patient satisfaction questionnaires in plastic surgery. Data extraction and descriptive statistics were used to summarize the data.

Results

A total of 105 studies were included. General/overall satisfaction was the most common topic addressed (99.04%). Cosmetic outcomes were the most frequently assessed category (34.3%). Breast reconstruction was the most common procedure (33.3%). Most studies used a combination of generic and procedure-specific questionnaires (45.71%). The most frequently used measurement tools were BREAST-Q and self-developed questionnaires, each accounting for 28.57% and 27.61%.

Conclusions

This review provides a comprehensive analysis of patient satisfaction questionnaires in plastic surgery, emphasizing the importance of a holistic approach and well-established, validated tools. The findings contribute to improving plastic surgery outcomes and enhancing the quality of care. Future research should refine assessment tools to address patients' needs and promote patient-centered outcomes in plastic surgery.

Complications and Risks Associated With the Different Types of Abdominoplasties: An Analysis of 55,956 Patients

BACKGROUND

Different types of abdominoplasties have been developed to address individual patient characteristics. However, an analysis of complication rates and risk factors for different types of abdominoplasties has yet to be reported.

OBJECTIVES

The aim of this study was to evaluate the complication rates and risks associated with each type of abdominoplasty.

METHODS

Utilizing the CosmetAssure database, patients undergoing an abdominoplasty from 2015 to 2022 were identified. Demographic factors and major complications were recorded and analyzed with a chi-square test or analysis of variance. A logistic regression was performed to identify the risk for developing complications associated with each type of abdominoplasty.

RESULTS

A total of 55,596 patients underwent an abdominoplasty procedure by any method. The overall complication rate was 2.1%. There was a significant difference in the overall complication rates of all 7 types of abdominoplasties (P < .05), with fleur-de-lis abdominoplasty having the highest complication rate. The year of surgery, being underweight or morbidly obese, having diabetes, and being male placed patients at a significantly higher risk for developing a postoperative complication. Over 15,000 patients (27.2%) had concurrent procedures related to breast surgery, other body contouring, liposuction, or facial surgery. When accounting for various risk factors in a regression model, there was no significant added risk for major complications after a combination procedure with an abdominoplasty compared to abdominoplasty alone.

CONCLUSIONS

Among the different types of abdominoplasties, a fleur-de-lis abdominoplasty has the highest complication rate. Concurrent cosmetic procedures with an abdominoplasty showed no added risk for major complications when compared to abdominoplasty alone.

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.

Abdominal Panniculectomy: Determining the Impact of Diabetes on Adverse Outcomes and Complications

Background: Despite its association with obesity, the relation between diabetes and the abdominal panniculectomy is less well-established. The purpose of this study was to evaluate the result of diabetes on post-panniculectomy complications in a large cohort and to establish the risk factors associated with unfavorable post-operative outcomes. Methods: Patients that underwent a panniculectomy between 2010 and 2018 were identified in PearlDiver, a national insurance claims database, and identified by Current Procedural Terminology code 15380. Patient demographics and comorbidities were elucidated, and various complications were then identified. Descriptive statistics as well as a multivariate analysis were used to evaluate the association of risk factors and complications. Results: A total of 8282 panniculectomy patients were identified-4245 with diabetes, 4037 without. Obesity, tobacco use, and diabetes were all identified as significant risk factors in developing a surgical site infection, wound disruption, as well as needing to undergo reoperation. Diabetic panniculectomy patients had a higher rate of readmission as well as reoperation and sustained a higher rate of surgical complications, even when matched for. Conclusion: Diabetic panniculectomy patients are at a greater risk for developing complications. Identifying potential risk factors in this patient population could help reduce post-operative complications following a panniculectomy.

Outpatient-Based High-Volume Liposuction: A Retrospective Review of 310 Consecutive Patients

BACKGROUND

Currently, the definition of large-volume liposuction is the removal of 5 L or more of total aspirate. Higher volumes of lipoaspirate come into consideration with higher BMIs, because more than 5 L is often required to achieve a satisfactory aesthetic result. The boundaries of what lipoaspirate volume is considered safe are based on historical opinion and are constantly in question.

OBJECTIVES

Because to date there have been no scientific data available to support a specific safe maximum volume of lipoaspirate, the authors discuss necessary conditions for safe high-volume lipoaspirate extraction.

METHODS

This retrospective study included 310 patients who had liposuction of ≥5 L over a 30-month period. All patients had 360° liposuction alone or in combination with other procedures.

RESULTS

Patient ages ranged from 20 to 66 with a mean age of 38.5 (SD = 9.3). Average operative time was 202 minutes (SD = 83.1). Mean total aspirate was 7.5 L (SD = 1.9). An average of 1.84 L (SD = 0.69) of intravenous fluids and 8.99 L (SD = 1.47) of tumescent fluid were administered. Urine output was maintained above 0.5 mL/kg/hr. There were no major cardiopulmonary complications or cases requiring blood transfusion.

CONCLUSIONS

High-volume liposuction is safe if proper preoperative, intraoperative, and postoperative protocols and techniques are employed. The authors believe that this bias should be modified and that sharing their experience with high-volume liposuction may help guide other surgeons to incorporate this practice with confidence and safety for better patient outcomes.

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.

The Use of Mean Gray Value (MGV) as a Guide to Tension-Reducing Strategies in Body Contouring Surgery Reduces Wound-Related Morbidity

BACKGROUND

Currently there are no known structural parameters of the integument that can be measured noninvasively which are used in the planning of body contouring surgery.

OBJECTIVES

The aim of this study was to see if mean gray value (MGV), when taken into account preoperatively, can reduce wound-related morbidity.

METHODS

This project was a prospective cohort study. Ultrasound imaging of the subcutaneous tissue was performed prospectively on patients undergoing body contouring surgery to quantify the superficial fascial system so that average MGV could be calculated over the proposed surgical sites. Patients with average to poor MGV (≤0.127) were identified preoperatively for tension-reducing procedures. Wound complication rates were compared with rates in a retrospective cohort which did not undergo preoperative imaging.

RESULTS

There were 115 patients in each of the 2 cohorts. There were 3 exclusions due to loss of ultrasound images, leaving 112 patients available for analysis in the prospective cohort. The cohorts were similar except for a higher incidence of patients with diabetes in the retrospective group (1 vs 9, P = 0.026). The wound complication rate was significantly reduced in the prospective group (5/112, 4.4%) when compared with the retrospective group (20/115, 17%, P = 0.0062). The revision and infection rates were also significantly reduced in the prospective group (1/112, 0.9%; 3/112, 2.6%) when compared with the retrospective group (8/115, 7%, P = 0.019; 10/115 8.6%, P = 0.051).

CONCLUSIONS

MGV is a unique, patient- and area-specific structural parameter of the integument, and its measurement may be useful in reducing wound-related morbidity in body contouring surgery.

Retrospective Analysis of Predictive Factors for Complications in Abdominoplasty in Massive Weight Loss Patients

INTRODUCTION

Ex-obese patients present with redundancy of abdominal skin and soft tissue due to massive weight loss (MWL). The plastic surgeon can restore the body shape through body contouring procedures. Hence the need to adequately direct patients to body contouring by identifying suitable candidates exists. Our work aims to retrospectively analyze the abdominoplasty complications in our case series to identify associated risk factors and evaluate the effect of combined procedures on abdominoplasty outcomes.

MATERIALS AND METHODS

We retrospectively investigated predictive factors of abdominoplasty procedure complications on 213 MWL patients who received abdominoplasty with and without rectus sheath plication, abdominal liposuction, and other body contouring procedures. We identified risk and protective factors with univariate and multivariate regression analysis. Furthermore, we assessed the impact of additional procedures on the complication rates.

RESULTS

The overall complication rate was 49.8% (26.8% minor complications; 23% major complications). The delayed wound healing rate was 27.7%, and the revision surgery rate was 25.8% (14.7% early revision; 14.2% late revision). These results were compared with literature reports. Several negative predictors emerged as non-modifiable (advanced age, diabetes mellitus, surgical mode of weight loss) or modifiable (preoperative obesity and body mass index (BMI); active smoking; preoperative anemia; use of fibrin glue or quilting sutures). Performing rectus sheath plication improved most of the outcomes. Liposuction of hypochondriac regions and flanks led to increased safety and reduced the risk of surgical dehiscence and delayed wound healing, in contrast to epimesogastric liposuction. The other combined body contouring procedures did not worsen the outcomes, except for poor scarring.

CONCLUSION

Our findings encourage us to continue associating rectus sheath plication, liposuction, and other body contouring surgeries with abdominoplasty. We emphasize the importance of proper patient selection, particularly with regard to anemia, before body contouring surgery in the interests of offering safe surgery and satisfactory results. Further studies are needed to investigate how the optimal BMI cut-off and abstinence from smoking (in terms of time) before surgery reduce postoperative complications.

The Association Between Metabolic Derangement and Wound Complications in Elective Plastic Surgery

INTRODUCTION

The incidence of metabolically unhealthy obesity is rising nationally. In this study, we compare wound and overall complications between metabolically unhealthy obese and healthy patients undergoing elective plastic surgery and model how operative time influences a complication risk.

METHODS

Patients undergoing elective breast and body plastic surgery procedures in the 2009-2019 National Surgical Quality Improvement Program (NSQIP) dataset were identified. Complications were compared between metabolically unhealthy obese (body mass index [BMI] > 30 with diabetes and/or hypertension) versus metabolically healthy obese patients (BMI > 30 without diabetes or hypertension). Logistic regression was used to model the probability of wound complications across operative times stratified by metabolic status.

RESULTS

Of 139,352 patients, 13.4% (n = 18,663) had metabolically unhealthy obesity and 23.8% (n = 33,135) had metabolically healthy obesity. Compared to metabolically healthy patients, metabolically unhealthy patients had higher incidence of wound complications (6.9% versus 5.6%; P < 0.001) and adverse events (12.4% versus 9.6%; P < 0.001), in addition to higher 30-d readmission, returns to the operating room, and length of stay (all P < 0.001). After adjustment, BMI (Odds ratio [OR] 7.86), hypertension (OR 1.15), and diabetes (OR 1.25) were independent risk factors for wound complications (all P < 0.001). Among metabolically unhealthy patients, the operative time was log-linear with a wound complication risk (OR 1.21; P < 0.001).

CONCLUSIONS

Diabetes and hypertension are additive risk factors with obesity for wound complications in elective plastic surgery. Among patients with metabolically unhealthy obesity, a risk of wound complications increases logarithmically with operative time. This distinction with regard to metabolic state might explain the unclear impact of obesity on surgical outcomes within existing surgical literature.

Functional panniculectomy vs cosmetic abdominoplasty: Multicenter analysis of risk factors and complications

BACKGROUND

Amidst the rising trend of bariatric surgical procedures being performed across the country and around the world, patients seeking functional panniculectomy after massive weight loss represent a different population than those seeking cosmetic abdominoplasty. The purpose of this study was to determine whether certain complications are more likely to occur in patients undergoing functional panniculectomy, as well as identify risk factors that are implicated in the occurrence of adverse events.

METHODS

Retrospective cohort study was conducted of patients undergoing cosmetic abdominoplasty and functional panniculectomy in North America between 2015 and 2019 using the National Surgical Quality Improvement Program database sponsored by the American College of Surgeons. Comorbidities and postoperative complications between these two cohorts were analyzed with appropriate statistics.

RESULTS

During the study interval, 11,137 patients underwent excision of excessive infraumbilical abdominal skin, including 57.4% (n = 6397) patients undergoing functional panniculectomy and 42.6% (n = 4740) patients undergoing cosmetic abdominoplasty. Patients undergoing functional panniculectomy were significantly more likely to have comorbidities than those undergoing cosmetic abdominoplasty (p < .001). Overall adverse events (p < .001), medical complications (p = .047), surgical complications (p < .001), related readmission (p < .001), and related reoperation (p < .001) were significantly higher in patients undergoing functional panniculectomy. Surgical complications significantly higher in functional panniculectomy included superficial incisional infection (p < .001), deep incisional infection (p < .001), organ/space infection (p < .001), dehiscence (p = .003), and bleeding requiring transfusion (p = .003).

CONCLUSIONS

Patients undergoing functional panniculectomy are significantly more likely to have comorbidities and experience postoperative wound infection, dehiscence, sepsis, bleeding, related readmission, and related reoperation.

[The effect of body mass index on outcome of body contouring surgeries]

BACKGROUND

The generalization of bariatric surgery interventions has led in recent years to an explosion in demand for body contouring surgeries. These operations can be followed by postoperative complications; and residual obesity, defined by a BMI≥30, is traditionally considered as a relative contraindication. The objective is to study the influence of a BMI≥30 on the risk of postoperative complications.

METHODS

A retrospective study was conducted on all patients who underwent body contouring surgery between 2014 and 2020 at the Arras Hospital Center. Major complication rates were compared in obese and non-obese patients.

RESULTS

Two hundred twenty-three patients were included, representing a total of 247 surgeries: 124 in the BMI<30 group and 123 in the BMI≥30 group. Sixteen surgeries were followed by at least one major complication, 6 in group I versus 10 in group II (RR=1.7 (0.6-4.5), NS, P=0.29). Therefore there were not significantly more major complications in obese patients.

CONCLUSION

The incidence of major complications following body contouring surgeries is not modified by the presence of a BMI greater than 30, subject to a precautionary procedure adapted to each patient. BMI is therefore not a sufficient criterion to contraindicate this type of surgery.

Evaluating Outcomes and Weight Loss After Panniculectomy

OBJECTIVE

The objective of this study was to evaluate long-term outcomes and weight loss after panniculectomy.

METHODS

A retrospective chart review study was performed on 225 consecutive patients who had undergone panniculectomy from 2002 and 2020. Demographic variables including smoking status, medical comorbidities, and prior history of weight loss/bariatric surgery were collected for 173 patients. Preoperative and postoperative body mass index (BMI) were calculated in addition to postoperative outcomes.

RESULTS

The study population was 85% female with a mean age of 57 years and an average follow-up of 3.9 years. Relevant comorbidities included obesity (88%), hypertension (65%), diabetes (37%), and smoking (8%), and the majority (53%) of patients had undergone prior bariatric surgery. The overall complication rate was 40%. Twenty percent of patients required reoperation or readmission, and 20% had minor complications addressed in an outpatient setting. Patients who had higher preoperative BMI experienced a significant long-term reduction in BMI. In addition, patients who did not undergo prior bariatric surgery tended to lose weight more often and by larger amounts than patients who had prior bariatric surgery (71.6% vs 57.6, P = 0.023). Complications were not uncommon and included infection (17%), delayed wound healing (16%), seroma (8%), and hematoma (3%). Patients who had prior bariatric surgery were at reduced risk of any complication (P = 0.012). Smoking increased the incidence of infection (38.5% of smokers vs 15.6% of nonsmokers, P = 0.039). Concomitant hernia repair increased the risk of overall complications (64.3% vs 35.9%, P = 0.003) and delayed wound healing (39.2% vs 11.7%, P < 0.001). In the subgroup of patients who did not lose weight, a panniculus weight greater than 5 kg was associated with an increased complication rate (61.5% vs 27%, P = 0.03).

CONCLUSIONS

Patients who underwent a panniculectomy tended to lose weight postoperatively, particularly those who had not undergone previous bariatric surgery. Complications were not uncommon, especially in patients with a smoking history. Prior bariatric surgery patients had a significant decrease in postoperative complications but tended to lose less weight after panniculectomy than those without prior bariatric surgery. Concomitant hernia repair put patients at an increased risk of complications.

Abdominal Body Contouring: Does Body Mass Index Affect Clinical and Patient Reported Outcomes?

BACKGROUND

Obese individuals are thought to be higher risk for complications after excisional abdominal body contouring (EAC) due to co-morbidities and significant tissue resection.

OBJECTIVES

We comparatively analyzed EAC patients with Body Mass Index (BMI) ≥35 kg/m² and BMI <35 kg/m² to highlight key differences in clinical and patient-reported-outcomes (PROs).

METHODS

Patients ≥18 years-old undergoing EAC by a single surgeon from 01/2018-01/2020 were identified and separated into cohorts based on BMI (<35 and ≥35 kg/m²). Patients were excluded if they had a cosmetic abdominoplasty without history of bariatric surgery or massive weight loss, or if they had <1000 gs of tissue resected. Clinical outcomes and PROs using the BODY-Q were comparatively analyzed.

RESULTS

70 total patients with median BMIs of 30[26-32] and 41[37-45] kg/m² in each cohort, were identified. Patients with BMI ≥35 kg/m² were more likely to have higher ASA (P<0.01) and use of incisional negative pressure wound devices (P = 0.042). Alternatively, they were less likely to have had concurrent liposuction (P = 0.05). There were no differences in development of an SSO, SSI or SSOpi (P>0.05) between cohorts. Multivariate logistic regression showed that BMI ≥35 kg/m², iNPWD and liposuction were not associated with the development of complications. PROs demonstrated improvement in multiple domains despite BMI.

CONCLUSION

There was no association with BMI ≥35 kg/m² and the development of complications within our cohort. We encourage preoperative weight loss when possible, however these procedures can be performed safely with acceptable outcomes even in individuals who are obese and/or require extensive tissue removal.

Local Triamcinolone Treatment Affects Inflammatory Response in Seroma Exudate of Abdominoplasty Patients: A Randomized Controlled Trial

BACKGROUND

As the leading complication of abdominoplasty, seroma formation might represent an inflammatory process in response to surgical trauma. This prospective randomized trial investigated whether local administration of the antiinflammatory agent triamcinolone could prevent seroma accumulation.

METHODS

Weekly and cumulative seroma volumes were compared between the study groups A, B, and C over a 4-week follow-up (group A, with drain, without triamcinolone; group B, without drain, without triamcinolone; group C, without drain, with triamcinolone). Aspirated seroma samples were analyzed by enzyme-linked immunosorbent assay for selective inflammatory mediators.

RESULTS

Triamcinolone significantly reduced cumulative seroma volume (n = 60; mA 845 ± SDA 578 ml, mC 236 ± SDC 381 ml, p = 0.001). The most accentuated suppressive effect of triamcinolone was observed shortly after the treatment (week 1) (mA1 616 ± SDA1 457 ml, mB1 153 ± SDB1 161 ml, mC1 22 ± SDC1 44 ml, pA1/C1 < 0.001, pB1/C1 = 0.014). Local triamcinolone administration resulted in a differential concentration of interleukin-6 (IL-6) and matrix metalloproteinase-9 (MMP-9 (week 1) in seroma exudate as measured by enzyme-linked immunosorbent assay (mIL-6A1 1239 ± SDA1 59 pg/ml, mIL-6C1 848 ± SDC1 80 pg/ml, p < 0.001; mMMP-9A1 2343 ± SDA1 484 pg/ml, mMMP-9C1 376 ± SDC1 120 pg/ml, p = 0.001).

CONCLUSIONS

Local administration of 80 mg of triamcinolone reduced postabdominoplasty seroma accumulation significantly. Under triamcinolone treatment, suppressed levels of IL-6 and MMP-9 in seroma fluid were observed. Notably, inflammatory marker suppression correlated clinically with a decrease in seroma accumulation.

The Effect of Obesity, Bariatric Surgery, and Operative Time on Abdominal Body Contouring Outcomes

BACKGROUND

Abdominal body contouring procedures are associated with the highest rates of complications among all aesthetic procedures. Patient selection and optimization of surgical variables are crucial in reducing morbidity and complications.

OBJECTIVES

The purpose of this single-institution study was to assess complication rates, and to evaluate BMI, operative time, and history of bariatric surgery as individual risk factors in abdominal body contouring surgery.

METHODS

A retrospective chart review was performed of all patients who underwent abdominoplasty, circumferential lower body lift, fleur-de-lis panniculectomy (FDL), and circumferential FDL between August 2014 and February 2020. Endpoints were the incidence of venous thromboembolism, bleeding events, seroma, infection, wound complications, and reoperations. Univariate statistical analysis and multivariate logistic regressions were performed. Covariates in the multivariate logistic regression were BMI, procedure time, and history of bariatric surgery.

RESULTS

A total of 632 patients were included in the study. Univariate analysis revealed that longer procedure time was associated with infection (P = 0.0008), seroma (P = 0.002), necrosis/dehiscence (P = 0.01), and reoperation (P = 0.002). These associations persisted following multivariate analyses. There was a trend toward history of bariatric surgery being associated with minor reoperation (P = 0.054). No significant increase in the incidence of major reoperation was found in association with overweight or obese patient habitus, history of bariatric surgery, or prolonged procedure time. BMI was not found to be an individual risk factor for morbidity in this patient population.

CONCLUSIONS

In abdominal body contouring surgery, surgery lasting longer than 6 hours is associated with higher incidence of seroma and infectious complications, as well as higher rates of minor reoperation.

Avoidance and Correction of Deformities in Body Contouring

Body contouring procedures are highly impactful because of their potential to improve a patient's quality of life. These procedures, particularly when performed on patients following massive weight loss, may require secondary intervention to treat residual contour abnormalities. Presently, there is a paucity of information in the literature detailing the avoidance and correction of body contouring deformities. Herein, we will discuss the management of patients seeking revisional body contouring procedures.

Abdominoplasty complications - what additional risks do postbariatric patients carry?

PURPOSE

Particular trends of postoperative complications following abdominoplasty are seen when patients present with a history of bariatric surgery. This study aims to analyze the risk factors for complications following abdominoplasty among those who did and did not undergo prior bariatric weight loss surgery.

METHOD

Data of 144 patients who underwent abdominoplasty at our institution between 2009 and 2015 were reviewed. Prevalence of existing comorbidities and incidences of postoperative complications were recorded, and statistical analysis was carried out to establish differences between our cohorts.

RESULTS

Of 144 patients, 49 patients had prior bariatric surgery and 95 patients did not undergo surgery. There was no statistically significant difference between the groups for the prevalence of diabetes mellitus, coronary artery disease, hypertension, and anemia, although differences did exist for hypothyroidism and smoking history (p = 0.04 and 0.037, respectively). Postbariatric patients had more comorbidities than nonbariatric patients (p = 0.024). Postoperatively, there was no statistically significant difference between the groups for incidences of hematoma, necrosis, active bleeding, and symptomatic decrease in Hb, although differences did exist for infection (OR = 13.12), seroma (OR = 9.07), prolonged healing (OR = 5.28), and abundant drain secretions (OR = 5.24). Male gender and prior bariatric surgery were associated with higher overall rates of postoperative complications.

CONCLUSIONS

Our findings validate the results of prior studies that report a higher prevalence of underlying comorbidities and postoperative complications among postbariatric surgery patients undergoing abdominoplasty. Furthermore, prior bariatric surgery was found to be an independent risk factor for the presence of any (OR 4.78 and p < 0.001) and major (OR 4.050 and p = 0.018) complications after abdominoplasty.

Quality of Life and Complications in the Morbidly Obese Patient following Post-Bariatric Body Contouring

BACKGROUND

With a growing obesity epidemic, an increasing number of patients are seeking body contouring procedures (BCP). The aim of this study was to assess the association of morbid obesity (BMI > 40 kg/m2) with both clinical and health-related quality of life (H-RQOL) outcomes following BCP.

METHODS

Patients evaluated for post-bariatric BCP at a large academic hospital by one surgeon were retrospectively identified. Patients were surveyed using the BODY-Q^© during initial and postoperative visits. Demographic, clinical, operative characteristics, and surgical outcomes data were extracted. BODY-Q domain scores were compared between morbidly obese (MO) and non-morbidly obese (NMO). The absolute change in HR-QOL scores for MO and NMO was also compared.

RESULTS

Overall, 59 patients were included (MO 72.9% vs. NMO 27.1%). The median age was 50 years old (Interquartile range [IQR] ± 17); the majority were non-Hispanic (89.8%), non-diabetic (81.4%), non-smokers (67.8%). Assessment of surgical site occurrences, reoperations, and the complication composite outcome revealed no statistical differences between groups (p >0.05). MO patients showed lower net improvement in three HR-QOL domains: satisfaction with body (median 30 [IQR ± 53] vs. 65 [IQR ± 54]; p = 0.036), body image (median 39 [IQR ± 55] vs. 52 [IQR ± 44]; p = 0.025), and social function (median 12 [IQR ± 18] vs. 19 [IQR ± 35]; p = 0.015).

CONCLUSION

Post-bariatric BCP can be safely performed in the MO patient without increased risk of complication. However, the benefit of truncal BCP is less in MO as it pertains to specific QOL domains: satisfaction with body, body image, and social function.

Health technology assessment through the six sigma approach in abdominoplasty: Scalpel vs electrosurgery

Abdominoplasty is a surgical procedure conducted to reduce excess abdominal skin and fat and improve body contouring. Despite being commonly performed, it is associated with a risk of complications such as infection, seroma, haematoma and wound dehiscence. To reduce the incidence of complications, different methods are used to create the abdominal flap, i.e., incision with a scalpel or electrosurgery. In this study, health technology assessment (HTA) using the Six Sigma methodology was conducted to compare these incision techniques in patients undergoing abdominoplasty. Two consecutively enroled groups of patients (33 in the scalpel group and 35 in the electrosurgery group) who underwent surgery at a single institution, the University of Campania "Luigi Vanvitelli", were analysed using the drain output as the main outcome for comparison of the incision techniques. While no difference was found regarding haematoma or seroma formation (no cases in either group), the main results also indicate a greater drain output (p-value<0.001) and a greater incidence of dehiscence (p-value=0.056) in patients whose incisions were made through electrosurgery. The combination of HTA and the Six Sigma methodology was useful to prove the possible advantages of creating skin incisions with a scalpel in full abdominoplasty, particularly a significant reduction in the total drain output and a reduction in wound healing problems, namely, wound dehiscence, when compared with electrosurgery, despite considering two limited and heterogeneous groups.

What Is the Impact of Residual Obesity on the Risk for Postoperative Body-Contouring Surgery Complications in Postbariatric Patients?

BACKGROUND

There are an increasing number of patients presenting for plastic surgery after massive weight loss, and many of these patients have residual obesity that may compromise outcomes. The impact of residual obesity on the development of postoperative complications in postbariatric patients undergoing plastic surgery procedures is unclear.

METHODS

We report the outcomes of 207 patients who underwent plastic surgery following RYGB from January 2011 to December 2018.

RESULTS

Two hundred and seven patients (196 females, 11 males) with a mean age of 42 years underwent 335 separate operations. The average BMI at the time of plastic surgery was 27.43 kg/m². The average weight loss was 47.08 kg. The prevalence of comorbidities was 26.6% and the most important presurgery comorbidities were arterial hypertension (10.1%) and diabetes mellitus (4.8%). Of the 207 patients who underwent surgery, 78.3% (168/207) underwent abdominoplasty and 45.0% underwent mammoplasty. The overall rate of complications was 27.5%. The prevalence of postoperative complications was not significantly different between patients with a BMI ≥ 30 kg/m² and patients with a BMI < 30 kg/m² (33.3% vs 25.9%, respectively; p = 0.344).

CONCLUSION

In this group of patients, with specified anthropometric and clinical profiles, the residual obesity did not influence the incidence of postoperative complications in postbariatric patients after plastic surgery.

Vertical Abdominoplasty Technique and the Impact of Preoperative Comorbidities on Outcomes

Background

As the number of patients requiring bariatric surgery has increased, so has the demand for body contouring after massive weight loss. Surgery involving the abdomen in these patients is particularly challenging as both vertical and horizontal laxity if often present, making traditional abdominoplasty techniques less effective.

Objectives

The aim of this study was to review the operative technique and evaluate the preoperative comorbidities and operative decisions that may impact patient outcomes in those undergoing vertical abdominoplasty.

Methods

A review of the authors' technique is described. A retrospective chart review of patients who underwent vertical abdominoplasty for significant vertical and horizontal laxity after massive weight loss by a single surgeon between June 2007 and July 2019 was performed. Preoperative parameters, operative factors, and minor and major complications were evaluated.

Results

Our complication rate was 81% (13/16), which were all minor. No major complications were encountered. Patients with a history of nicotine use had a 100% complication rate. There was a trend toward higher seroma formation in patients with coronary artery disease and those with a history of smoking. There was also a trend toward higher wound dehiscence in patients with renal disease. The authors found no statistically significant correlation between complications and older age, higher weight of tissue resected, higher body mass index, and medical comorbidities.

Conclusions

This small series helps to elucidate the role of vertical abdominoplasty in the care of patients following massive weight loss and its associated morbidity. Proper patient selection, appropriate preoperative patient counseling, and sound surgical technique help to mitigate the negative outcomes.

Standards and Trends in Lipoabdominoplasty

BACKGROUND

Lipoabdominoplasty has evolved over the last 6 decades through contributions from numerous luminaries in plastic and reconstructive surgery.

METHODS

The authors review historical perspective and provide a contemporary examination of trends in lipoabdominoplasty.

RESULTS

In 1967, Pitanguy popularized abdominoplasty (without liposuction) as a technique for augmenting ventral hernias repairs and subsequently for aesthetic improvement of the abdomen. After the introduction of suction assisted lipectomy by Illouz in 1983, abdominoplasty became a central tool in a diverse armamentarium of anterior and lateral abdominal wall contouring procedures. Liposuction was initially utilized with mini-abdominoplasty in order to improve contour. Subsequently, Matarasso advanced the safe combination of liposuction with full abdominoplasty. Additionally, he systematized the variety of cutaneous undermining, excision, and liposuction procedures utilized in abdominal contouring as indicated by the degree of skin laxity and musculofascial diastasis. Lockwood advocated high lateral tension closure of the superficial fascial system of the abdomen to improve the contour of the hips and flanks. Saldanha advanced selective undermining and anterior abdominal wall perforator preservation to minimize wound healing and seroma complications associated with lipoabdominoplasty procedures.

CONCLUSION

In abdominal contour surgery, surgeons can rely on classic techniques and algorithms that have withstood the test of time while modifying their approaches with advances backed by compelling and rigorously obtained evidence.

Abdominoplasty and Patient Safety: The Impact of Body Mass Index and Bariatric Surgery on Complications Profile

BACKGROUND

Abdominoplasty is a frequent aesthetic surgical procedure. Despite its popularity, patient safety requires further attention because of an important risk of complications. Obesity and bariatric surgery are potential risk factors. This study evaluated the impact of body mass index (BMI) and bariatric surgery on complications profile.

METHODS

A retrospective review of patients undergoing abdominoplasty over a 5-year period was conducted. Patient demographics, comorbidities, BMI, bariatric surgery, complications (minor and major) and drainage outcomes were evaluated. Univariate and multivariate logistic regression analyses were performed for risk assessment.

RESULTS

The 191 study patients showed an overall complication rate of 32.5%, comprising minor (27.7%) and major complications (7.9%). Seroma was the most common complication (20.9%). Mean BMI was 27.1 kg/m². Obesity was present in 14.1%, and bariatric surgery in 53.4%. Obese patients had significant higher rates of overall complications (74.1%, p < 0.001), minor complications (66.7%, p < 0.001), seroma (51.9%, p < 0.001) and drainage outputs (p < 0.001). Bariatric patients showed an increased time (p = 0.003) and volume of drainage (p < 0.001), without significant differences in complications. Obesity and preoperative BMI were the only independent risk factors for overall complications (OR 8.3; and OR 1.3; p < 0.001), minor complications (OR 7.4; and OR 1.3; p < 0.001) and seroma (OR 4.5; and OR 1.2; p = 0.002). Diabetes was an independent risk for major complications (OR 4.6; p = 0.047).

CONCLUSION

Obesity has negatively impacted the profile and risk of complications, whereas bariatric surgery independently did not. Our study provides an accurate understanding of abdominoplasty complications, allowing better risk stratification, candidate selection refinement, morbidity reduction, fair patient counseling and overall improvement in patient safety.

Anterior abdominal wall reconstruction with mesh implants: indications and limitations in a developing tropical economy

INTRODUCTION

the role of surgery in managing massive midline abdominal wall defects has continued to rise, leading to higher demand for more effective techniques in order to limit recurrences. There is paucity of data on this subject in Southeast Nigeria. The aim of this study is to document the indications and challenges of treatment of complex, midline abdominal wall defects in our centre.

METHODS

this was a cross-sectional study of adult patients with complex, midline abdominal wall defects managed with mesh implants over a five-year period.

RESULTS

a total of 182 adult patients, predominantly females 160(87.9%), received mesh implants for complex abdominal wall defects. The common indications were incisional hernia 128(70.3%), abdominal wound dehiscence 16(8.8%) and divarication of recti 16(8.8%). About one-third 62(34.1%) of the patients required additional abdominoplasty procedure. Delay towards prompt surgical repair was noted in 168(92.3%) patients, notably due to financial constraints 32(17.6%) followed by comorbidities requiring serial assessments 24(13.2%). Superficial wound infection rate was 5.5% while deep (mesh) infection was noted in two (1.1%) patients. Recurrence and perioperative mortality rates were 1.1% and 1.6% respectively. Diabetes mellitus in obese female patients was an independent predictor of perioperative death (p=0.000).

CONCLUSION

the most common indication for abdominal wall reconstruction in our environment is incisional hernia. The use of prosthetic meshes to repair complex abdominal wall defects is largely safe and effective in our practice, but timely reconstruction is commonly hampered by multi-faceted economic, clinical and pathological barriers.

Large extended abdominoplasty-dispelling the myths of prohibitively high BMI's: a case report

Abdominoplasty is one of the most highly requested cosmetic procedures in the USA. Although it is famed for its cosmetic value, there are few reports that discuss its therapeutic potential. Furthermore, few abdominoplasties are completed in patients over the body mass index (BMI) of 30 due to fears of increased complications.

A 63-year-old male presented due to development of a large pannus following weight loss postgastric bypass. Unfortunately, because of this pannus, the patient began experiencing significant physical and emotional distress. The patient had difficult urinating, ambulating and could no longer engage in sexual activity. The patient underwent abdominoplasty for removal of the pannus. At the 5-month follow-up, patient exhibited resolution of his symptoms.

Abdominoplasty should not be limited to cosmetic procedures. It holds therapeutic value, and the BMI should not be listed as a firm contraindication to the procedure.

Abdominoplasty for treatment of abdominal gun-shot wound sequalae – A case report

•

Limited literature exists on abdominoplasty for therapeutic purposes.

•

Patient arrived with emotional distress related to lasting gunshot injury scar.

•

Abdominoplasty was completed for revision of the gunshot injury.

•

Plastic surgeons should be creative in their techniques for revision.

Background

Gun violence is a public health epidemic in the United States with 15,315 non-suicide related deaths reported in 2019 by the Gun Violence Archive. To date, abdominoplasty is primarily a cosmetic procedure, which involves low-lying incision, removal of excess skin, fat, and tissue, and strengthening of the abdominal wall musculature. There currently are limited reports in regard to abdominoplasty as a procedure for scar revision and abdominal deformity repair associated with gunshot related injuries.

Methods

An African American female patient, 38 years of age, presented for correction of a wide healed surgical incision and incisional hernia in the midline abdomen. This resulted from a trauma laparotomy in treatment of multiple gunshot wounds.

Results

Patient presented post-operatively with no complications. She had successful reduction of her incisional hernia using an anatomic repair. Her wide hypertrophic abdominal scar was excised and primarily closed.

Conclusion

In the cases of abdominal hernia and scarring secondary to trauma laparotomies performed for gunshot wounds, abdominoplasty is an option for revision and repair.
