Body contouring after obesity surgery is associated with a weight loss benefit among patients

Analyzing the Impact of Social and Psychiatric Factors in Patients Who Undergo Body Contouring Procedures

BACKGROUND

As the prevalence of obesity increases, the number of patients seeking body contouring procedures after bariatric surgery for massive weight loss is increasing. Although the positive impact of bariatric surgery on physical and emotional health is well-described, few studies have reported on the psychosocial well-being of patients undergoing body contouring procedures. Psychosocial well-being can impact patient satisfaction and maintenance of weight loss, and is an important area to study.

OBJECTIVE

The aim of this study was to characterize social and psychiatric factors of patients undergoing body contouring surgery, and to evaluate their impact on maintenance of weight loss.

METHODS

A retrospective review was performed of patients who presented to a single institution for body contouring procedures between 2002 and 2018. Demographic details, medical history, psychosocial support, and operative details were collected. Univariate analysis and multinomial logistic regressions were performed with R statistical software (version 1.3.1093).

RESULTS

A total of 1187 patients underwent at least 1 body contouring procedure during the study time frame. Mean BMI at presentation was 31.21 ± 10.49 kg/m2. Patients diagnosed with obesity at age 18 or older had significantly greater odds of suffering from generalized anxiety disorder (odds ratio [OR] 1.08 [95% CI, 1.02-1.15], P = .008). Patients with spousal support had 1.93 times higher odds of having maintained postbariatric weight loss at their 6-month follow-up (OR 1.93 [95% CI, 1.84-2.01], P = .028).

CONCLUSIONS

Social support and age of obesity diagnosis impact psychological well-being and maintenance of weight loss following body contouring procedures.

Weight Control following Body Contouring Surgery: Long-Term Assessment of Postbariatric and Nonbariatric Patients

BACKGROUND

Few reports of weight maintenance following body contouring (BC) surgery present weight measurements as percentage weight change, and most of these studies do not isolate BC to specific body areas. This study analyzed weight control in the trunk-based BC population and further compared BC outcomes in postbariatric and nonbariatric patients.

METHODS

The authors performed a retrospective cohort study of consecutive postbariatric and nonbariatric patients who underwent trunk-based BC (abdominoplasty, panniculectomy, and circumferential lipectomy) from January 1, 2009, through July 31, 2020, at West Virginia University. A minimum 12-month follow-up was required for inclusion. With BC surgery date as the reference point, percentage total weight loss was assessed at 6-month intervals for 2 years following BC and every year thereafter. Change over time was compared between postbariatric and nonbariatric patients.

RESULTS

Within the 12-year timeframe, 121 patients meeting criteria underwent trunk-based BC. Average follow-up from date of BC was 42.9 months. Sixty patients (49.6%) had previously undergone bariatric surgery. From before BC to endpoint follow-up, postbariatric and nonbariatric patients experienced a 4.39% ± 10.93% and 0.25% ± 9.43% increase in weight from baseline, respectively ( P = 0.0273). Once nadir weight loss was attained, weight regain occurred through endpoint follow-up in both groups (11.81% in the postbariatric cohort and 7.56% in the nonbariatric BC cohort; P = 0.0106).

CONCLUSIONS

Long-term weight regain is common following trunk-based BC operations-specifically, in postbariatric patients. Although this should not contend with the psychological benefit of removing this excess tissue, it is important to report results with ideal weight metrics to optimally assess outcomes in this population.

Analysis of Body Contouring and Sustained Weight Loss in a Diverse, Urban Population: A 7-Year Retrospective Review

BACKGROUND

Studies demonstrating the positive impact of body contouring on sustained weight loss in bariatric patients describe a narrow cohort. The authors sought to evaluate the impact of postbariatric body contouring procedures on sustained weight loss in minority race patients.

METHODS

A retrospective review of bariatric surgery patients at a single institution was performed. Patients were grouped as follows: (1) those who underwent body contouring, (2) those who had consultation but did not undergo body contouring, and (3) those without consultation. Body mass index (BMI) and excess body weight loss (EBWL) over 7 years were the primary outcomes.

RESULTS A TOTAL OF

2531 patients were analyzed: 350 in group 1, 364 in group 2, and 1817 in group 3. At postoperative year 7, groups 1 and 2 had average BMIs 4.71 and 2.31 kg/m 2 lower than group 3, respectively, while adjusting for covariates. After exclusion of 105 patients in group 2 who were not offered body contouring because of inadequate weight loss, however, group 2 had an average BMI 4.07 kg/m 2 lower than group 3 at postoperative year 7. During postoperative year 1, group 1 had an average EBWL of 74.38%, which declined 1.51% yearly, and group 2 had an average EBWL of 70.12%, which declined 1.86% yearly. After exclusion of the aforementioned patients, group 2 had an average EBWL of 74.9% at postoperative year 1, which declined 1.88% yearly.

CONCLUSIONS

Body contouring after bariatric surgery did not impart a clinically significant, long-term sustained weight loss benefit in the authors' cohort. In the authors' study population, patients identifying as black had significantly worse sustained weight loss.

Prolonged postoperative antibiotic administration reduces complications after medial thigh lift

There is widespread consensus that there is no indication for postoperative antibiotic administration after elective surgery. However, medial thigh lift (MTL) remains a procedure with a notoriously high rate of wound-healing disorders and infections. This study investigates the correlation between prolonged antibiotic administration and complications after MTL in massive weight loss patients. We performed a single-institution retrospective review of 121 patients undergoing MTL between 2009 and 2020. Data on postoperative outcome, demography, surgery and comorbidities were collected. All patients received intravenous antibiotics preoperatively. One group was continued on oral antibiotics for two weeks postoperatively. Complications and surgical site infections were observed and evaluated. There was no difference between the groups regarding age, BMI, or presence of obesity-associated risk factors. We observed complications in 76 patients (71%), with 60 (56%) minor and 16 (15%) major complications. The group without prolonged antibiotic administration had a higher number of total complications (OR 3.5; p = 0.0037), major complications (OR 4; p = 0.01), and wound infections (OR 6.8; p = 0.0004). Logistical regression analysis showed that this effect was independent of type of weight loss, resection volume, and age. Reduction of major infections by prolonged antibiotics was, however, dependent on BMI Δ. No side-effects associated with antibiotics were registered in this series. This study suggests that prolonged antibiotic administration may decrease complications in MTL. We thus continue to use prolonged antibiotic administration after MTL. Further research is needed to determine the optimal duration of antibiotic treatment. Level of Evidence: Level IV: therapeutic study.

A Prospective, Matched Comparison of Health-Related Quality of Life in Bariatric Patients following Truncal Body Contouring

BACKGROUND

Massive weight loss after bariatric surgery can lead to excess skin associated with functional and aesthetic sequelae. Access to the benefit provided by body contouring procedures may be limited by insurance approval, which does not consider health-related quality of life. The aim of this study was to quantify the benefit in health-related quality of life for patients who undergo body contouring procedures after massive weight loss.

METHODS

Patients evaluated for postbariatric body contouring procedures were systematically identified and prospectively surveyed using the BODY-Q. Health-related quality-of-life change for each functional scale was compared between those who underwent body contouring procedures (operative group, preoperatively versus postoperatively) and those who did not (nonoperative group, preoperatively versus resurvey) using t tests. Propensity score matching allowed the authors to balance baseline demographics, comorbidities, physical symptoms, and risk factors between cohorts.

RESULTS

Fifty-seven matched patients were analyzed (34 operative versus 23 nonoperative). No significant difference in age, body mass index, time between surveys, or preoperative BODY-Q scores existed between cohorts. The surgical group demonstrated a significant improvement in 10 out of 11 BODY-Q functional scales. The nonoperative group realized no improvements and, in the interim, had a significant deterioration in four BODY-Q scales.

CONCLUSIONS

Postbariatric body contouring procedures represent a critical and final step in the surgical weight loss journey for patients and are associated with significant improvements in health-related quality of life. Further deterioration in psychosocial and sexual health-related quality of life occurs in patients who do not undergo body contouring procedures following bariatric surgery. This study provides prospective comparative data that validate the field's standard intervention and justification for insurance approval.

Body Contouring Surgery Improves Weight Loss after Bariatric Surgery: A Systematic Review and Meta-Analysis

INTRODUCTION

Our main objective is to evaluate the effect of body contouring surgery (BCS) on the magnitude and durability of weight loss after bariatric surgery.

METHODS

Medline, EMBASE, Cochrane, and Scopus search were conducted from the time of their inception to June 2020. We included comparative studies that assessed weight progression, in terms of Body Mass Index change (∆BMI), Total Body Weight Loss (TBWL%), and Excess Weight Loss (%EWL) for the post-bariatric patient population and the effect of BCS on weight progression.

RESULTS

Eleven articles were included. The pooled sample size was 2307, of which 691 were cases who underwent BCS post-bariatric surgery, and 1616 were comparative controls. The mean follow-up time for cases and controls were 61.6 ± 23.8 months and 52.2 ± 23.8 months, respectively. Nine studies reported results of BMI changes, six provided %EWL, and five used %TBWL. Significant improvement in weight loss was observed in the BCS group when measured by either ∆BMI (3 kg/m2 points decrease, p 0.023), %TBWL (6% increase, P < 0.0001), or %EWL (14% increase, P < 0.0001). Sub-group analysis showed that increased follow-up time was associated with higher TBWL% (p 0.02).

CONCLUSION

The evidence provided in this review strongly supports the added long-term benefits of body contouring surgery for selected patients after massive weight loss following bariatric surgery. Having a multidisciplinary team that involves a bariatric and a plastic surgeon as well as nutritionists and psychologists for the management of patients with obesity going through the bariatric pathway is recommended.

The Edmonton Obesity Staging System as a predictor for postoperative complications after medial thigh lift in massive weight loss patients

BACKGROUND

This study investigates the correlation between the Edmonton Obesity Staging System (EOSS) and the occurrence of postoperative complications after medial thigh lift in formerly obese patients.

PATIENTS AND METHODS

A single-institution retrospective review of patients undergoing medial thigh lift between 2009 and 2019 after massive weight loss. Data on demography, comorbidities, surgery, and postoperative outcome were extracted from patients' charts. Patients were grouped into EOSS categories. Complications were classified into minor and major. Logistic regression analysis was performed to determine the association between risk factors and complications.

RESULTS

One hundred and eight patients were included in the study. Complications occurred in 76 (70%) of the patients, most of which were minor (60/108, 56%). Complications increased with increasing EOSS stage, and all EOSS 3 patients had complications. Classification as EOSS 2 or 3 significantly associated with occurrence of postoperative complications (OR 99.3, p<0.001) as well as minor and major complications individually (OR 3.1 and 6.5, p<0.05). This effect was independent of body mass index (BMI), maximum BMI loss, type of weight loss, volume of liposuction, weight of resected tissue, and type of surgery.

CONCLUSION

EOSS is a robust and independent predictor for postoperative complications in medial thigh lift surgery after massive weight loss.

OBJECTIVE

The development of these updated clinical practice guidelines (CPGs) was commissioned by the American Association of Clinical Endocrinologists (AACE), The Obesity Society (TOS), American Society for Metabolic and Bariatric Surgery (ASMBS), Obesity Medicine Association (OMA), and American Society of Anesthesiologists (ASA) Boards of Directors in adherence with the AACE 2017 protocol for standardized production of CPGs, algorithms, and checklists.

METHODS

Each recommendation was evaluated and updated based on new evidence from 2013 to the present and subjective factors provided by experts.

RESULTS

New or updated topics in this CPG include: contextualization in an adiposity-based chronic disease complications-centric model, nuance-based and algorithm/checklist-assisted clinical decision-making about procedure selection, novel bariatric procedures, enhanced recovery after bariatric surgery protocols, and logistical concerns (including cost factors) in the current health care arena. There are 85 numbered recommendations that have updated supporting evidence, of which 61 are revised and 12 are new. Noting that there can be multiple recommendation statements within a single numbered recommendation, there are 31 (13%) Grade A, 42 (17%) Grade B, 72 (29%) Grade C, and 101 (41%) Grade D recommendations. There are 858 citations, of which 81 (9.4%) are evidence level (EL) 1 (highest), 562 (65.5%) are EL 2, 72 (8.4%) are EL 3, and 143 (16.7%) are EL 4 (lowest).

CONCLUSIONS

Bariatric procedures remain a safe and effective intervention for higher-risk patients with obesity. Clinical decision-making should be evidence based within the context of a chronic disease. A team approach to perioperative care is mandatory, with special attention to nutritional and metabolic issues.

The BAPRAS screening tool for reimbursement in a postbariatric population

INTRODUCTION

Reimbursement of body-contouring surgery (BCS) is a worldwide problem: there is no objective instrument to decide which postbariatric patients should qualify for reimbursement. The British Association of Plastic, Reconstructive and Aesthetic Surgeons (BAPRAS) has developed a screening tool for this purpose. In this study, we used a modified version of this screening tool in a postbariatric population and describe which patients would qualify for reimbursement using this tool.

METHODS

In this cross-sectional study postbariatric patients were asked to fill in an online questionnaire based on the BAPRAS screening tool with questions regarding complaints of overhanging skin and medical history. Weight loss data were extracted from a prospective database. The BODY-Q was added to assess patient-reported outcomes.

RESULTS

Patients who wanted to undergo BCS (n = 90) had higher screening tool scores and lower BODY-Q scores compared to patients who did not want BCS (n = 24). In total, 25 patients (26%) qualified for reimbursement, these patients had higher weight loss (33.5% versus 29.2%, p = 0.008), lower BMI (27.3 kg/m² versus 30.4 kg/m², p = 0.014) and more medical (4.0 versus 2.0, p = 0.004) and psychological complaints (88% versus 61%, p = 0.009). There was a significant, negative correlation between the screening tool scores and almost all BODY-Q scales.

CONCLUSIONS

Patients with a desire for BCS have more complaints of excess skin, which negatively impacts their well-being. With the modified BAPRAS screening tool, patients with the best weight (loss) and most medical and psychological complaints of excess skin qualified for referral and reimbursement of BCS.

Skin Protein Profile after Major Weight Loss and Its Role in Body Contouring Surgery

Chronic inflammation during morbid obesity significantly alters cutaneous tissue. Large weight loss achieved after bariatric surgery minimizes or halts damage caused by metabolic syndrome, but further deteriorates the clinical condition of skin. Postbariatric skin flaccidity produces major difficulties to plastic surgery. In this study, we analyzed differences in protein composition of the skin between patients with morbid obesity and those after large weight loss and established correlations between differentially expressed proteins and clinical characteristics of postbariatric skin tissue, to improve body contouring surgery techniques.
