Abdominoplasty With Scarpa Fascia Preservation

Decreasing Seroma Incidence Following Abdominoplasty: A Systematic Review and Meta-Analysis of High-Quality Evidence

Background

Seroma formation is the most common complication of abdominoplasties. Many preventive interventions have been proposed, but none have been recognized as a definitive solution, partly due to varying levels of evidence (LOE) in the literature.

Objectives

We aimed to analyze seroma prevention methods supported by high-level evidence.

Methods

The PubMed database was queried through August 2023. Primary articles of interest included randomized controlled trials (RCTs), prospective comparative studies, and meta-analyses of these studies. The LOE for each article was determined according to the American Society of Plastic Surgeons Rating Scale. The "seroma occurrence ratio," or ratio of seroma events in the interventional group to respective control group, was calculated to compare incidence rates between techniques.

Results

Twenty articles and 9 categories of techniques were analyzed. Study designs included 10 RCTs, 2 prospective cohort studies, 7 prospective comparative studies, and 1 retrospective randomized study. The use of progressive-tension and quilting sutures had the most data supporting a statistically significant reduction in seroma (occurrence ratio 0.306, P < .001). Tissue adhesives and preservation of Scarpa's fascia were also well reinforced (0.375, P < .01 and 0.229, P < .011, respectively), while increasing the number of drains was not (P = .7576). Meta-analysis demonstrated that compared with 2 drains alone, alternative techniques were more effective at reducing seroma occurrence (pooled risk ratio 0.33, 95% CI, 0.11-0.99).

Conclusions

This review highlights multiple seroma prevention techniques for abdominoplasty investigated in recent high-quality literature. We suggest future randomized comparative studies of the various seroma prevention methods to fully ascertain their efficacy following abdominoplasty.

Level of Evidence 1

Lipoabdominoplasty with Anatomical Definition: Update

There is a continuous search for better technical alternatives for the treatment of abdominal contour deformities in the practice of plastic surgeons. LADE-lipoabdominoplasty (LAP) with anatomical definition-is a step ahead of the traditional LAP technique. This technique incorporated the principles of highlighting the definition of the abdominal musculature, achieving more natural results with fewer reminders of a surgical intervention. The esthetic results are much harmonious, with a true abdominal rejuvenated appearance. We can reduce morbidity by the preservation of perforating blood vessels and suspension of Scarpa's fascia. The correct selection of the patient makes the procedure safe and reproducible.

Postbariatric Abdominoplasty: A Comparative Study on Scarpa Fascia Preservation Versus Classical Technique

BACKGROUND

Abdominoplasties performed with Scarpa Fascia preservation, improve recovery and reduce complications, particularly seroma. Bariatric patients who experience massive weight loss frequently seek body contouring procedures and represent a high-risk group. This study aimed to evaluate the effects of abdominoplasty with Scarpa Fascia preservation versus the classical technique in a bariatric population.

METHODS

A retrospective observational cohort study was performed between March 2015 and March 2021 in 65 postbariatric patients who underwent a classic full abdominoplasty (group A, N = 25) or a similar procedure except for the preservation of Scarpa fascia (group B, N = 40). Total and daily drain output, time until drain removal, long drainers (≥ 6 days), length of hospital stay, emergency department visit, readmission to the hospital, reoperation, local and systemic complications were the outcomes evaluated.

RESULTS

Group B had a 3-day reduction in time until drain removal (p < 0.001), a 62.6% reduction of total drain output (p < 0.001) and a 3-day reduction in the length of the hospital stay (p < 0.001). Long drainers (≥ 6 days) were highly reduced (from 56.0% in group A to 7.5% in group B) (p < 0.001). There was a lower incidence of liquid collections in group B, with a 66.7% reduction in seroma incidence.

CONCLUSIONS

Abdominoplasty with Scarpa Fascia preservation improves recovery by reducing drain output, allowing earlier drain removal and reducing long periods with suction drains. It also reduces hospital stay and seroma incidence. This technique modifies the high-risk postbariatric patient in such a major way that he behaves like a nonbariatric.

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.

Detection of Lymphatic Vessels in the Superficial Fascia of the Abdomen

Recently, the superficial fascia has been recognized as a specific anatomical structure between the two adipose layers-the superficial adipose tissue (SAT) and the deep adipose tissue (DAT). The evaluation of specific characteristics of cells, fibers, blood circulation, and innervation has shown that the superficial fascia has a clear and distinct anatomical identity, but knowledge about lymphatic vessels in relation to the superficial fascia has not been described. The aim of this study was to evaluate the presence of lymphatic vessels in the hypodermis, with a specific focus on the superficial fascia and in relation to the layered subdivision of the subcutaneous tissue into SAT and DAT. Tissue specimens were harvested from three adult volunteer patients during abdominoplasty and stained with D2-40 antibody for the lymphatic endothelium. In the papillary dermis, a huge presence of lymphatic vessels was highlighted, parallel to the skin surface and embedded in the loose connective tissue. In the superficial adipose tissue, thin lymphatic vessels (mean diameter of 11.6 ± 7.71 µm) were found, close to the fibrous septa connecting the dermis to the deeper layers. The deep adipose tissue showed a comparable overall content of lymphatic vessels with respect to the superficial layer; they followed the blood vessel and had a larger diameter. In the superficial fascia, the lymphatic vessels showed higher density and a larger diameter, in both the longitudinal and transverse directions along the fibers, as well as vessels that intertwined with one another, forming a rich network of vessels. This study demonstrated a different distribution of the lymphatic vessels in the various subcutaneous layers, especially in the superficial fascia, and the demonstration of the variable gauge of the vessels leads us to believe that they play different functional roles in the collection and transport of interstitial fluid-important factors in various surgical and rehabilitation fields.

Scarpa Fascia Preservation to Reduce Seroma Rate on Massive Weight Loss Patients Undergoing Abdominoplasty: A Comparative Study

(1) Background: An increasing number of patients undergo bariatric surgery and seek body contouring surgery after massive weight loss (MWL). Abdominoplasty itself is associated with a high complication rate in these patients, particularly due to seroma formation. Scarpa fascia preservation (SFP) has been proven to be an efficient method of reducing seroma rates. We aimed to evaluate the possible benefits of SFP on massive weight loss patients comparatively. (2) Methods: This is a single-center retrospective comparative study encompassing 202 MWL patients operated between 2009 and 2019 at Turku University Hospital. Patients included in the study had a preoperative weight loss greater than 30 kg. Of them, 149 went through traditional abdominoplasty and 53 abdominoplasties with SFP. The primary outcome measure was seroma occurrence, while secondary outcomes included drainage amount, hospital stay, surgical site occurrence, and need for blood transfusion. (3) Results: The only statistically significant difference between groups on patients' demographics was the sex ratio, favoring females in the control group (43:10, 81% vs. 130:19, 87%, p = 0.018). SFP significantly reduced seroma occurrence (9.4% vs. 26.2%, p = 0.011) and decreased mean drainage duration (3.7 ± 2.4 vs. 5.3 ± 3.2 days, p = 0.025). There was a trend towards lower drainage output (214.1 ± 162.2 mL vs. 341.9 ± 480.5 mL, p = 0.060) and fewer postoperative days on ward in the SFP group. Other complication incidences did not differ between the groups. The multivariable analysis did not show any significant factor for seroma formation or surgical site occurrence. (4) Conclusions: Preserving Scarpa fascia on MWL patients may result in decreased seroma occurrence and a shorter time to drain removal.

Abdominoplasty with Scarpa Fascia Preservation: A Systematic Review and Meta-analysis

BACKGROUND

Scarpa fascia preservation has been proposed to minimize complications associated with conventional abdominoplasty, but its efficacy is unclear. The purpose of this article is to determine the influence of preserving scarpa fascia on reducing postabdominoplasty complications.

METHODS

A comprehensive search of Medline Ovid, PubMed, Web of Science, and the Cochrane CENTRAL databases was conducted from the inception till June 2021. Eligible studies were prospective controlled studies investigating postoperative complications after scarpa fascia preservation following abdominoplasty. Stata 15.1 software was used for the meta-analysis.

RESULTS

The meta-analysis included seven studies with 682 abdominoplasty patients. Abdominoplasty with scarpa fascia preservation could significantly reduce incidence of seroma (OR = - 1.34, 95% CI = - 2.09 - - 0.59, P < 0.05), length of hospital stay (SMD = - 1.65; 95% CI = - 3.50-0.20; P = 0.08), time to drain removal (SMD = - 3.64; 95% CI = - 5.76 - - 1.52; P < 0.05), and total drain output (SMD = - 401.60; 95% CI = - 593.75 - - 209.44; P < 0.05) compared with that of conventional abdominoplasty. However, it failed to achieve a statistically significant reduction in hematoma (OR=- 1.30, 95% CI = - 2.79-0.18, P = 0.08), infection (OR = - 1.03; 95% CI = - 2.17-0.12; P = 0.08), skin necrosis (OR = 0.63; 95% CI = - 1.20-2.45; P = 0.50), and wound dehiscence (OR = 0.28; 95% CI = - 0.28-0.83; P = 0.33). The seroma incidence rate was lower when a scalpel was utilized for dissection rather than electrocautery (3% (95% CI = 1-7%) versus 11% (95% CI = 5-18%)).

CONCLUSIONS

Preservation of scarpa fascia during abdominoplasty might reduce the likelihood of postoperative seroma, length of hospital stay, time to drain removal, and total drain output. However, it did not significantly affect the incidence of hematoma, infection, skin necrosis, and wound dehiscence.

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.

A Ruler for Abdominoplasty Preoperative Markings: The Potential of Best Scar Symmetry

Background. Scar appearance is an important outcome in abdominoplasty surgery, and its asymmetry can have a significant impact on patient and surgeon satisfaction. Here, we compared the scar symmetry reached with a ruler specially designed for the preoperative marking in abdominoplasty to the classic preoperative incision marking. Methods. In this randomized, uni-blind study, 42 patients were allocated to 2 different groups. Group 1 patients had their preoperative marking made by a group of surgeons that used the classic technique as described by Baroudi (n = 21), and Group 2 patients received their preoperative marking by another group of surgeons, using a ruler specially designed to fit the abdominal contour (n = 21). Patients were evaluated using a standard questionnaire that collected information about general patient's characteristics. On the follow-up period, we evaluated the presence of late surgical complications, need for revision surgery, patient's satisfaction concerning the postoperative scar, and 4 distances were measured in both groups to assess symmetry. Statistical analysis was made. Results. A total of 42 patients underwent abdominoplasty and were evaluated on the follow-up period (mean time: 4 months). The mean difference of corresponding measures on each side (A-B vs. A-B' and A-C vs. A-C') was higher in Group 1 comparing to Group 2. The level of correlation between corresponding measurements was higher in Group 2. Better satisfaction regarding the scar symmetry was achieved in Group 2, being this result statistically significant (P = .004). Conclusions. The use of the specialized ruler may help surgeons achieve a better scar symmetry with higher patient satisfaction.

Dissection Technique for Abdominoplasty With Scarpa Fascia Preservation: Comparative Study on Avulsion Technique Versus Diathermocoagulation

BACKGROUND

Many strategies have been developed to lower the high complication rate associated with a full abdominoplasty. The dissection technique may have a role to achieve this goal.

OBJECTIVES

The present study compared 2 different dissection techniques to perform a full abdominoplasty with Scarpa fascia preservation: avulsion technique and electrodissection.

METHODS

A retrospective observational cohort study was performed in 2 health institutions from January 2005 to January 2019. A total of 251 patients were involved: 122 patients submitted to abdominoplasty employing the avulsion technique (Group A) and 129 with diathermocoagulation (coagulation mode) (Group B). The latter was further divided into group B1 (57 patients with device settings according to surgeon's preferences) and B2 (72 patients with a specific regulation aiming at minimal tissue damage). Several variables were analyzed: population characteristics, time of hospital stay, time to drain removal, total and daily drain output, emergency department visits, readmission, reoperation, and local and systemic complications.

RESULTS

The general characteristics of both groups did not statistically significantly differ except for previous abdominal surgery. The diathermocoagulation group had a significantly lower length of hospital stay and time to drain removal. Moreover, these advantages were maximized when electrocautery was conducted with a specific low-voltage setting as significant differences were found. The other outcomes were identical.

CONCLUSIONS

Limiting the extension of electrodissection with the avulsion technique did not present any advantage. Utilizing diathermocoagulation (coagulation mode) during a full abdominoplasty with Scarpa fascia preservation, especially when it is aimed at minimal tissue damage, reduces patients' time with drains.

[Abdominoplasties: Do we still need to drain in 2021?]

OBJECTIVE

The purpose of this study was to consider the use of drainage when performing an abdominoplasty with regards to postoperative complications for two groups of patients.

PATIENTS AND METHOD

From January 1st 2017 to December 31th 2019, 215 patients underwent an abdominoplasty in our institution. In this retrospective, comparative, single institution study, patients were divided into two groups: "drainage" D (n=162) when suction completed abdominoplasty, "no drainage" ND (n=53) when suction didn't completed abdominoplasty. Early and distant complications were retrieved for each group and compared.

RESULTS

There was no significant difference between the two groups concerning the occurrence of seroma postoperatively (8% of patients in group D and 11.3% of patients in group AD). The drainage group D experienced more seroma's punctures (2,3± 1,0) and the mean of punctured fluid was higher (386,5ml±350,4ml) compared to the no drainage group ND (1,3+- 0,5 number of punctures with a mean punctured fluid of 165,8mL± 224,2mL). The mean hospital stay was shorter for group ND (2,9± 1,8 days) than for group D (4,4+- 1,7 days), P<0,0001.

CONCLUSION

Performing an abdominoplasty with quilting suture but drainless doesn't seem to increase postoperative complications statistically. The authors recommend, under the guise of a quilting suture, not to systematically drain the abdominoplasties and to reserve this technique for patients at risk of complications (high BMI, significant weight loss and co-morbidities).

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.

Abdominoplasty with Scarpa Fascia Preservation: Randomized Controlled Trial with Assessment of Scar Quality and Cutaneous Sensibility

BACKGROUND

Scarpa fascia preservation during abdominoplasty has been shown to reduce complications associated with the traditional technique. As an extension of a previously published randomized controlled trial, this study aims to clarify whether preservation of Scarpa fascia during abdominoplasty has an influence on scar quality or sensibility recovery.

METHODS

This was a single-center clinical trial, involving 160 patients randomly assigned to one of two surgical procedures: classic full abdominoplasty (group A) and abdominoplasty with preservation of Scarpa fascia (group B). Patients were later convoked to assess scar quality and abdominal cutaneous sensibility. Scar quality was evaluated through the Patient and Observer Scar Assessment Scale. Cutaneous sensibility was measured on the upper and lower abdomen, using light touch, Semmes-Weinstein testing (5.07/10-g monofilament), and a 25-gauge needle.

RESULTS

A total of 99 patients (group A, 54 patients; group B, 45 patients) responded to contact, with a mean follow-up time of 44 months. Concerning scar quality, Patient and Observer Scar Assessment Scale scores were similar between groups. On the upper abdomen, there was a statistically significant difference between groups on cutaneous sensibility, on the examination with the Semmes-Weinstein 5.07/10-g monofilament (group A, 79.6 percent; group B, 93.3 percent; p = 0.046) and pain (group A, 90.7 percent; group B, 100 percent; p = 0.044). No statistically significant differences were found between groups on the lower abdomen. A considerable proportion of patients (two-thirds) still presented sensibility alterations in the subumbilical area 3½ years after abdominoplasty.

CONCLUSION

Scarpa fascia preservation during abdominoplasty does not influence scar quality, but it improves sensibility recovery in the supraumbilical area.

Surgical treatment of diastasis recti: the importance of an overall view of the problem

PURPOSE

Diastasis recti (DR) is characterized by an alteration of the linea alba with increased inter-recti distance (IRD). It is more frequent in females, and when symptomatic or associated with midline hernia it needs to be surgically repaired. This retrospective study aims to demonstrate how an overall approach to DR leads to good results in terms of functional and morphological outcomes and quality of life (QoL).

METHODS

From January 2018 to December 2019, 94 patients were operated for DR > 50 mm, with or without midline hernias. Three different surgical approaches were used: complete laparoabdominoplasty, laparominiabdominoplasty and minimally invasive (endoscopic) technique. QoL was assessed with the EuraHS-QoL tool.

RESULTS

All patients were female except two males. We performed 26 endoscopic treatments (27.7%), 39 laparoabdominoplasties (41.5%) and 29 laparominiabdominoplasties (umbilical float procedure) (30.9%). The total median operative time was 160 min. No intraoperative complications were registered. In three (4.2%) cases, major surgical complications occurred, all after open operations. In 13 open surgery cases, vacuum-assisted closure (VAC) therapy was used to repair the cutaneous ischemic defect. No recurrence was registered to date. Minimally invasive surgery showed fewer complications and lower hospital stay than the open approach. The QoL was significantly improved.

CONCLUSION

Our experience shows the importance of an overall view of the functional and cosmetic impairment created by DR. The surgeon should obtain an optimal repair of the function, by open or minimally invasive surgery, also considering the morphological aspects, which are very important for the patients in terms of QoL.

[Research progress of abdominoplasty]

Objective

To summarize the research progress of abdominoplasty.

Methods

The literature related to abdominoplasty in recent years was reviewed and the evolution of this surgical method and related surgical techniques were summarized.

Results

By removing excess skin adipose tissue from abdominal wall and strengthening loosening muscle fascia system, the abdominal wall contour can be improved by abdominoplasty. With the development of liposuction, selective flaps undermining, progressive tension sutures, and Scarpa fascia retention, the trauma and complications of abdominoplasty are significantly reduced, and better aesthetic result is achieved.

Conclusion

At present, the incidence of abdominoplasty complication is still the highest among cosmetic surgeries, and further exploration is needed to reduce complications and improve aesthetic effects.
