Sub-Scarpa's Lipectomy in Abdominoplasty: An Analysis of Risks and Rewards in 723 Consecutive Patients

An In-Depth Analysis of 1370 Consecutive Abdominoplasties: Fascial Plication Increases Risk of Venous Thromboembolism, and Scoring for Plication Improves the Caprini Risk Assessment Model

BACKGROUND

Venous thromboembolism (VTE) is the most dangerous complication of abdominoplasty. One relatively undefined risk factor is plication, which in theory increases VTE risk.

OBJECTIVES

The aim of this study was to assess the thromboembolic risk of plication.

METHODS

A retrospective review of 1370 consecutive abdominoplasties by 1 surgeon was undertaken. Two groups were considered, plicated (n = 1089) and nonplicated (n = 281) patients, and VTE rates were compared between these groups.

RESULTS

There were 25 of 1089 cases of VTE (2.3%) in plicated patients and 1 of 281 cases of VTE (0.36%) in nonplicated patients, which was statistically significant (Fisher's exact test, P = .028) despite the nonplicated group being a higher-risk population. Case-control matching yielded 225 pairs which differed statistically only by the presence or absence of plication; there were 12 of 225 (5.3%) VTE events in the plicated group and 0 of 225 in the nonplicated group (McNemar's test, P = .0015). Logistic regression demonstrated increased VTE risk with increasing age (odds ratio [OR] 1.08, P < .001), BMI (OR 1.34, P = .002), Caprini score (OR 2.17, P < .001), and especially plication (OR 16.76, P = .008). Adding 2 points for plication to Caprini scores offered better risk stratification at a level of 7, with an improved combination of sensitivity and specificity (0.31/0.98 vs 0.69/0.96) and a 27% improvement over the 2005 Caprini risk assessment model (RAM) in the area under a receiver operating characteristic curve (0.826 vs 0.651, Z value -3.596, P = .003).

CONCLUSIONS

Plication was shown to be a powerful risk factor for the development of VTE in abdominoplasty. Abdominal wall plication should be considered in risk assessment, and scoring for plication may improve the performance of the Caprini RAM.

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

BACKGROUND

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

OBJECTIVES

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Biplanar Lipoabdominoplasty: Introducing the Subscarpal Lipo Aponeurotic System

Preservation of Scarpa’s fascia in abdominoplasty has been previously presented. Herein we introduce the subscarpal lipo aponeurotic system (SLAS) and the technique of preserving the SLAS and its tightening in lipoabdominoplasty.

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.

Abdominoplasty in the Massive Weight Loss Patient: Are Aesthetic Goals and Safety Mutually Exclusive?

Background

The goals of abdominoplasty in massive weight loss (MWL) patients are often functional, with a greater emphasis on safety than on aesthetic rejuvenation. As important as functional improvements and safety are, however, there may be room for increasing the aesthetic potential of abdominoplasties in these patients.

Objectives

To determine the safety of the pursuit of aesthetic goals for abdominoplasty in MWL patients.

Methods

This is a retrospective study examining 910 consecutive female patients consisting of 3 groups: postpartum (n = 718), dietary MWL (n = 65), and bariatric MWL (n = 127). All patients were approached with a well-defined set of aesthetic goals which were pursued as needed and as feasible.

Results

The utilization of aesthetic abdominoplasty components was similar in all groups, supporting the assertion that the groups were subjected to a similar aesthetic emphasis. Logistic regression showed that a history of bariatric MWL was an independent risk factor for multiple complications (odds ratio 2.738, P = 0.014) and that elevated body mass index (BMI), smoking, diabetes, and age were likewise independent risk factors for complications. Propensity score-matched case-control pairs showed that bariatric MWL patients were more likely than dietary MWL patients to experience multiple complications (9.52% vs 0%, P = 0.031).

Conclusions

Bariatric MWL patients but not dietary weight loss patients seem to have a higher risk than postpartum patients. Other comorbidities (elevated BMI, smoking, diabetes, and age) seem to be more important predictors of complications than MWL status. Select MWL patients can likely be approached with an emphasis on aesthetic goals, without increasing risks as compared with the postpartum population.
