Clinical outcome of patients undergoing abdominoplasty after massive weight loss

[Abdominoplasties and Suppurative Hydradenitis (Acne inversa) in Patients after Massive Weight Loss]

Post-bariatric surgical procedures in patients after massive weight loss (MWL) are often associated with elevated minor and major complications (17-55%). If there is additionally a long history of hydradenitis suppurativa (HS) in the lower abdomen and groin area, complications of infection can appear in all patients. Differentiated pre-, peri- and postoperative therapy regime is then indicated.From 2010 to 2021, a total of 12 (66.6% women, 33.3% men) consecutive patients underwent conventional (Pittsburg rating scale [PRS]: Grade 2) or fleur-de-lis abdominoplasty (PRS: Grade 3) after massive weight loss. All patients simultaneously suffered long term HS in the lower abdomen and groin area (Hurley classification Grade 2: n = 10, Grade 3: n = 2). The prevalence in our study was 1.09%.Postoperative minor and major complications (follow-up 12 months) are determined and correlated with risk factors (e.g. age, method of weight loss, nicotine abuse…).Mean age was 45.2 years (± 10.3), mean BMI pre-operative 33.24 kg/m² (± 8.7), the mean decrease in BMI was 19.01 kg/m² (± 5.9) and the maximum BMI before weight loss 52.25 kg/m². The mean duration of the suppurative hydradenitis was 31.5 years and n = 2 (17.0%) had current medical therapy against this. All patients showed further locations of the HS in other parts of the body and 66.6% had had surgical procedures because of the HS. 42.0% had nicotine abuse. The mean operation time was 98 minutes and the mean resection weight was 2210 grams. The overall complication rate was n = 10 (83.0%), and the rate of major complications n = 8 (66.4%) with surgical intervention in full anaesthesia. No patient had an infected haematoma, abscess or acute bleeding in the first 24 hours postoperatively.The antibiotic regime prevented the expected soft tissue infection in all patients. Inspection of the abdomen and groin area 4 weeks before surgery is recommended, in order to start preoperative therapy for the HS.

Incidence of Complications Associated With Lipectomy Techniques and Patient Body Mass Index: An Institutional and National Analysis Using the Tracking Operations and Outcomes for Plastic Surgeons

INTRODUCTION

An evaluation of complication rates in different abdominal lipectomy techniques with relationship to body mass index (BMI) and other risk factors.

METHODS

We identified patients who underwent an abdominal lipectomy at our institution from January 2015 to July 2020. Those with concurrent hernia repair were excluded. Patients were classified into 2 groups: (1) horizontal lipectomy with or without umbilical translocation and (2) inverted-T lipectomy with translocation. Demographics, operative details, and postoperative complications were collected for 1 year postoperatively. Bivariate analyses were conducted to determine factors associated with type of procedure and complications. Crude and stratum-specific (based on BMI) odds ratios for complications were calculated for the inverted T as compared with the horizontal group. A replicate analysis using the national Tracking Operations and Outcomes for Plastic Surgeons (TOPS) as a single cohort was performed.

RESULTS

At our institution, 362 patients (group 1 = 196, group 2 = 166) were included. A total of 40.9% of patients experienced at least one complication at 1 year postoperatively with the complication rate decreasing to 28.0% when analyzed at the 30-day postoperative period. Specifically, wound disruption rates were highest in group 2 (39.8%) compared with group 1 (15.6%; P < 0.0001). The odds of experiencing a complication were greater in the inverted-T group overall and within each stratum of BMI. When dividing the cohort based on BMI class (normal weight, overweight, class I, class II, and class III obesity), the incidence of wound disruption increased as did BMI (2.6%, 22.2%, 27.2%, 48.2%, and 56.3%, respectively; P < 0.0001). The TOPS data set included 23,067 patients and showed an overall complication rate of 13.1% at 30-day postop. Overall, wound disruption rate was 4.6%. Compared with normal weight patients, the odds of experiencing a complication trended higher with each stratum of BMI. Other factors associated with complications included BMI, tobacco use, diabetes, American Society of Anesthesiology, prior massive weight loss, and LOS.

CONCLUSIONS

The increasing complication rate within each BMI stratum of the large sample size of the TOPS patient cohort, in addition to our similar institutional trends, suggests that a staged procedure may be more appropriate for higher BMI patients. Surgical technique modification with limited flap undermining in patients undergoing inverted-T lipectomy to preserve flap perfusion may also decrease overall complication rates.

Clinic-morphological substantiation of the parahernial tissues excision in hernio-abdominoplasty in patients with ventral obesity

Objective. To formulate clinic-morphological substantiation for application of calculated excision of excessive and pathologically changed parahernial tissues together with performance of improved abdominoplasty in surgical interventions in patients with hernias in conditions of ventral obesity. Materials and methods. The investigation is based on data of paraoperative examinations and own results of surgical treatment of 58 herniological patients. Rational methods of their operating are substantiated by patho- and morphometric characteristics, determined in accordance to the observed dimensions of ventral hernia deformation, and content of the fat-containing, fibrous-cicatricial and inflammatory-pathological components in it. Results. The program set «Statistica 6.1»  was applied for elaboration of the results obtained. In accordance to own algorithm of the ventro- and sonometric investigations there was established, that the parahernial tissues extras in the patients with external hernias are localized and originated supraaponeurotically. Preoperative considerations concerning determination of optimal volumes of conduction of dermo- and fibro-lipectomies, performed before hernio-abdominoplasties on various hernias with signs of ventral obesity, have permitted to prevent the local purulent-inflammatory complications and to improve the indices of quality of life in the patient operated on. Conclusion. Application of the «with no surpluses» operating principle constitute a practical base for improvement of reconstructive-plastic  interventions results in external abdominal hernias and a real component of the problem decision in medic-social and esthetic rehabilitation of herniological patients with obesity.

Complications Post Abdominoplasty After Surgical Versus Non-surgical Massive Weight Loss: a Comparative Study

PURPOSE

This study aims to investigate the rate of short- and long-term complications as well as the need for operative revisions after abdominoplasty for patients following surgical versus non-surgical weight loss methods.

METHODS

This is a retrospective chart review that enrolled consecutive patients undergoing abdominoplasty across a 5-year period, aged 18 years and above, opting for abdominoplasty after weight loss achieved through bariatric surgery or diet and exercise alone.

RESULTS

A total of 364 patients lost weight through bariatric surgery and 106 by diet and exercise alone. There were no significant differences in comorbidity status, but past body mass index (BMI) was higher for the surgical weight loss (SW) group (47.6 ± 10.2 and 40.4 ± 8.6, respectively; p value < 0.0001). Percent excess weight loss (EWL) was 68 ± 14.5 for the SW group and 55.7 ± 19.4 for the NSW group, p value < 0.0001. Pre- and postoperative blood hemoglobin levels were significantly lower in the SW group (p < 0.05). Neither short-term complications (thromboembolic events, wound complications, or infections) nor long-term complications (umbilical deformity, delayed wound healing, or infection) and operative revisions were significantly different across both groups (p > .05).

CONCLUSION

Bariatric surgery does not increase the risk of short- or long-term complications or the need for operative revision after abdominoplasty.

The Impact of Obesity on Plastic Surgery Outcomes: A Systematic Review and Meta-analysis

BACKGROUND

Obesity is a potential risk factor for complications in plastic surgeries. However, the data presented by primary studies are contradictory.

OBJECTIVES

The aim of this study was to summarize and clarify the divergences in the literature to provide a better understanding of the impact of obesity in different plastic surgery procedures.

METHODS

We conducted a systematic review and meta-analysis of the impact of obesity on plastic surgery outcomes. Searches were conducted in MEDLINE, LILACS, SciELO, Scopus, Embase, Web of Science, Opengrey.eu, and the Cochrane Database of Systematic Reviews. The primary outcomes assessed were surgical complications, medical complications, and reoperation rates. The secondary outcome assessed was patient satisfaction. Subgroup analysis was performed to investigate the impact of each BMI category on the outcomes.

RESULTS

Ninety-three articles were included in the qualitative synthesis, and 91 were used in the meta-analysis. Obese participants were 1.62 times more likely to present any of the primary outcomes (95% CI, 1.48-1.77; P < 0.00001). The highest increase in risk among plastic surgery types was observed in cosmetic procedures (risk ratio [RR], 1.80; 95% CI, 1.43-2.32; P < 0.00001). Compared with normal-weight participants, overweight participants presented a significantly increased RR for complications (RR, 1.16; 95% CI, 1.07-1.27; P = 0.0004). Most authors found no relation between BMI and overall patient satisfaction.

CONCLUSIONS

Obesity leads to more complications and greater incidence of reoperation compared with nonobese patients undergoing plastic surgeries. However, this effect is not evident in reconstructive surgeries in areas of the body other than the breast.

The Age Factor in Postbariatric Body Contouring Surgery Outcome

BACKGROUND

Increasing life expectancy will likely lead greater numbers of older patients to seek postbariatric body contouring plastic surgery. The impact of age on body contouring plastic surgery outcome is undetermined.

METHODS

A retrospective cohort study of 317 postbariatric body contouring plastic surgery cases was performed. Patient demographics and operative and postoperative data were collected. Patients were categorized into three age groups, and univariate analysis examined group differences. Multivariate logistic regression analysis assessed independent associations between age and surgical outcome measures.

RESULTS

Patients 60 years and older had a higher mean preoperative body mass index (30.8 ± 3.6 kg/m2, p < 0.001) and higher rates of hypertension (48.9 percent, p < 0.001), dyslipidemia (38.3 percent, p < 0.001), and diabetes mellitus (17 percent, p = 0.012) compared to the younger age groups. They also sustained significantly higher complication rates (any minor complications, p = 0.004; minor surgical site infections, p = 0.005; minor hematomas, p = 0.007; any major complications, p < 0.001; major surgical-site infections, p < 0.001; and major dehiscence, p < 0.001). Increasing age was a significant risk factor for any major complications (p = 0.005), reoperation (p = 0.02), and readmission (p = 0.001). Age greater than or equal to 60 years was a significant risk factor solely for readmission (OR, 3.32; p = 0.03).

CONCLUSIONS

Increasing age was a risk factor for adverse postoperative outcome in postbariatric body contouring plastic surgery patients; however, age greater than or equal to 60 years in and of itself was an independent risk factor for readmission only. These findings may aid plastic surgeons in patient consultation and in decision making regarding suitable candidates for these procedures.

TULUA Male High-Definition Abdominoplasty

BACKGROUND

Abdominoplasty is a surgical technique for body contouring that has been shown to improve the patient's quality of life. It has become more common among male patients, so clear differences between procedures for men and women have to be stated. The authors present their experience with high-definition lipoabdominoplasty with transverse plication in men.

METHODS

Records of male patients undergoing transverse plication full abdominoplasty in addition to high-definition liposculpture were analyzed. A total of 24 consecutive cases were found between January of 2017 and June of 2019. Patient ages ranged from 24 to 60 years. Patients aged 18 years or younger were excluded. Body mass index ranged from 25 to 33 kg/m2. Photographic records were taken before and during follow-up at 2 days and 1, 3, 6, and 12 months after surgery.

RESULTS

Male TULUA (transverse plication, no undermining, full liposuction, neoumbilicoplasty, and low transverse abdominal scar) with high-definition lipoabdominoplasty was successfully achieved in 24 cases. No major complications were reported. Six minor complications were reported (25 percent). Rectus abdominis diastases are less common in men compared to women, as pregnancy is the most determining factor in its development. Fat distribution is also a key difference when performing lipoabdominoplasty for the male or the female patient. The authors recommend a transverse plication of the abdominal wall, instead of a vertical one, as flap viability is preserved and enhanced muscular definition can be accomplished.

CONCLUSIONS

Combining transverse plication with high-definition lipoabdominoplasty (transverse plication, no undermining, full liposuction, neoumbilicoplasty, and low transverse abdominal scar plus high-definition lipoabdominoplasty) is a safe and reproducible technique for the male patient. It offers higher aesthetic results in line with modern beauty ideals.

Association of Diabetes Mellitus With Postoperative Complications and Mortality After Non-Cardiac Surgery: A Meta-Analysis and Systematic Review

BACKGROUND

Although a variety of data showing that diabetes mellitus (DM) (Type 1 or Type 2) is associated with postoperative complication, there is still a lack of detailed studies that go through the specific diabetic subgroups. The goal of this meta-analysis is to assess the relationship between DM and various complications after non-cardiac surgery.

METHODS

We searched articles published in three mainstream electronic databases (PubMed, EMBASE, Web of science) before November, 2020. A random effects model was conducted since heterogeneity always exist when comparing results between different types of surgery.

RESULTS

This paper included 125 studies with a total sample size of 3,208,776 participants. DM was a risk factor for any postoperative complication (Odds ratio (OR)=1.653 [1.487, 1.839]). The risk of insulin-dependent DM (OR=1.895 [1.331, 2.698]) was higher than that of non-insulin-dependent DM (OR=1.554 [1.061, 2.277]) for any postoperative complication. DM had a higher risk of infections (OR=1.537 [1.322, 1.787]), wound healing disorders (OR=2.010 [1.326, 3.046]), hematoma (OR=1.369 [1.120, 1.673]), renal insufficiency (OR=1.987 [1.311, 3.013]), myocardial infarction (OR=1.372 [0.574, 3.278]). Meanwhile, DM was a risk factor for postoperative reoperation (OR=1.568 [1.124, 2.188]), readmission (OR=1.404 [1.274, 1.548]) and death (OR=1.606 [1.178, 2.191]).

CONCLUSIONS

DM is a risk factor for any postoperative complications, hospitalization and death after non-cardiac surgery. These findings underscore the importance of preoperative risk factor assessment of DM for the safe outcome of surgical patients.

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.

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.

The Impact of Post-bariatric Abdominoplasty on Secondary Weight Regain After Roux-en-Y Gastric Bypass

Roux-en-Y gastric bypass (RYGB), implies a considerable weight loss during the first two years after surgery. Excess skin due to rapid weight loss might affect self-esteem, decrease quality of life and be a hindrance to physical activity. Removing excess skin might reduce secondary weight regain. Among plastic surgeons, a BMI <30 kg/m² is usually required to have abdominoplasty (AP). Many RYGB patients never reach this threshold even if they have a considerable weight loss and experience practical as well as emotional problems due to excess skin. The aim of this study was to investigate the role of abominoplasty on weight development until five years, among patients who did and did not achieve a nadir BMI <30 kg/m² during the first two years after RYGB. Data on 645 patients from a single center RYGB-quality register from 2004 to 2013 with baseline and follow-up data were analyzed. Post-bariatric AP was publicly funded if medically needed. Weight regain (WR) from nadir weight to five years was analyzed as percentage WR of maximal weight loss. Nadir BMI was available in 633 (98.1%) patients, and BMI after five years in 553 (85.7%) patients. The 233 patients with nadir BMI <30 kg/m² who underwent AP regained 17.8 (±16.1) % of their maximal weight loss at five years compared to 24.2 (±19.7) % in 185 patients not having AP (p < 0.001). The 27 patients with nadir BMI > 30 kg/m² within two years after RYGB who underwent AP regained 12.9 (±19.3) % compared to 31.4 (±24.7) % in 188 patients without AP (p < 0.001). This procedure was more common among women than men, as 224 (46.4%) women, and 36 (22.2%) men underwent AP. Abdominoplasty was associated with reduced secondary weight regain after RYGB in this study. Whether this is caused by increased bodily satisfaction and better physical function, or a biological response to reduction of adipose tissue remains unclear. If removing abdominal subcutaneous adipose tissue prevent secondary weight regain and increase the robustness of bariatric surgery, this should be offered as part of the standard treatment after bariatric surgery.
