Analysis of Complications in Postbariatric Abdominoplasty: Our Experience

The Role of Helium Plasma-Assisted Liposuction in Lipoabdominoplasty After Weight loss

BACKGROUND

Weight loss patients present with major deformities, leading to the rapid development of new body contouring techniques to address their specificities. Abdominal skin laxity is often major due to rapid weight loss and inflammation secondary to bariatric surgeries and is often present in both vertical and horizontal axes. Through this article, the authors wish to demonstrate the use of helium plasma radiofrequency technology for supraumbilical skin tightening following lipoabdominoplasty.

METHODS

A retrospective single-center cohort study was performed, including 100 consecutive patients undergoing HPRF-assisted lipoabdominoplasty. Patient characteristics, intra- and postoperative outcomes and complications were collected. A postoperative Likert scale evaluated patient satisfaction at 6-month follow-up.

RESULTS

The mean age was 37, and the median preoperative BMI was 25.3. The median follow-up period was 19.7 months. Among the 100 included patients, no major complication occurred. Minor complications included wound dehiscence (1%), subcutaneous emphysema (2%), hyperpigmentation (8%), seroma (6%), and hematoma (2%). Overall satisfaction was high with 88% of 5/5 evaluations on the Likert scale.

CONCLUSION

HPRF-assisted lipoabdominoplasty stands as a safe and efficient refinement in post-bariatric patients and can be used to avoid vertical scars and decrease scar tension. This technology seems, therefore, valuable to enhance body contouring procedures while minimizing morbidity.

Combined Surgery (Mommy-Makeover) Compared to Single Procedure (Abdominoplasty) in After-Pregnancy Women: A Prospective Study on Risks and Benefits

BACKGROUND

Mommy-makeover is becoming very popular to help them reshaping their own bodies and restoring self-perception, hardly stressed by childbearing-related changes. However, debate exists in the literature concerning safety and aesthetic outcome in patients undergoing combined procedures. The study aims to shed a light on advantages and disadvantages in mommy-makeover technique compared to conventional abdominoplasty with a particular attention to psychological aspects.

MATERIALS AND METHODS

In total, 37 women were enrolled at Campus Bio-Medico Hospital in Rome between October 2019 and January 2022. All of the patients were eligible for both abdominoplasty only and mommy-makeover. We proposed to the patients both procedures explaining risks and benefits; then, based on the preference of the single patient, we performed either mommy-makeover (Group A) or abdominoplasty alone (Group B). In order to evaluate patients' satisfaction and safety, multiple questionnaires were administered 9-month postoperatively (BUT, POSAS, visual perception, etc.).

RESULTS

The sample analyzed was composed of 37 patients (treatment group = 18, control group = 19). In the pre-post comparisons of BUT-A performed, there were statistically significant differences recorded in both groups and for all observed variables. The significance values were all less than 1% (p < 0.01).

CONCLUSIONS

Combined surgery proved not to be inferior in terms of patient safety. At the same time, the effectiveness in improving diastasis-related symptoms is fully comparable with single surgery. Treatment group showcases a considerable superiority in terms of body-image perception improvement and overall patient satisfaction.

Closed Incision Negative Pressure Therapy Versus Traditional Dressings for Low Transverse Abdominal Incisions Healing by Primary Closure: A Systematic Review and Meta-Analysis

Background: Closed incision negative pressure therapy (ciNPT) devices may reduce wound healing complications when applied to closed surgical incisions. The aim of this review was to assess the effects of ciNPT versus standard dressings in patients undergoing primary closure of high tension, lower transverse abdominal incisions. Methods: This review was registered a priori on PROSPERO (CRD42021252048). A search of the following databases was performed in February 2021: Medline, EMBASE, and CENTRAL. Unpublished trials were searched using clinicaltrials.gov. All randomized and nonrandomized studies comparing ciNPT to standard dressings were included. Two independent reviewers performed screening and data extraction. Outcomes evaluated the incidence of wound dehiscence, surgical site infection, total abdominal complications, time to drain removal, and seroma formation. Main Results: Ten studies were included in quantitative and narrative synthesis. Observational study evidence suggests ciNPT likely reduces the incidence of wound dehiscence (odds ratio [OR] 0.57 [0.44-0.96], P = .03) and total abdominal complications (OR 0.34 [0.21-0.54], P < .01). Decreased incidence of seroma formation favored ciNPT (OR 0.65 [0.24-1.76], P = .40); however, this did not achieve significance. Randomized and non-randomized study evidence was very uncertain about the effect of ciNPT on the remaining outcomes. Conclusions: The current best randomized study evidence is very uncertain about the effect of ciNPT on these outcomes. Observational study evidence suggests ciNPT likely results in a statistically significant reduction in abdominal wound dehiscence and total abdominal complications. Additional randomized trials are warranted to limit the impact of bias on the overall certainty of the evidence.

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 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.

Umbilical reconstruction: different techniques, a single aim

The umbilicus is a unique physiologic scar of human life resulting from the healing process of the cut umbilical cord at birth. Its absence leads to an unnatural abdominal appearance, and an abnormally shaped or misplaced umbilicus may draw undue attention to the central abdomen. Loss of the umbilicus can be an embarrassing deformity; this occurs when older techniques of umbilical hernia or incisional hernia repair are employed and after abdominoplasty, urachal cyst repair, omphalocele repair, gastroschisis repair, some tumor excisions, and mobilization of bipedicled or bilateral TRAM/DIEP flaps for breast reconstruction. Umbilicoplasty, in which the umbilicus remains anchored to the deep abdominal fascia but is transposed through a newly-formed aperture in the upper abdominal skin flap, is performed in abdominoplasty either for abdominal flap harvest or purely for aesthetics. On the other hand, umbiliconeoplasty describes the de novo creation of an umbilicus that is absent for either congenital or acquired reasons. The optimal umbilical reconstruction should be reliable, reproducible, aesthetically appropriate, and associated with low morbidity. Ideally, it is also single-staged, except in the case of an infected wound, in which case a delayed primary approach may be prudent. (www.actabiomedica.it)

From liposuction to adipose-derived stem cells: indications and technique

Background and aim of the work:

Adipose tissue is an organ of energy storage, an endocrine organ, a soft tissue filler and a cosmetically unnecessary tissue discarded by liposuction. Liposuction was designed to correct unaesthetic deposits of subcutaneous fat; it produces satisfactory silhouette contouring when performed by appropriately trained operators using properly selected technologies. However, from lipoaspirate it is possible to obtain autologous fat graft and adipose-derived stem cells (ASCs) for reconstructive surgery and regenerative medicine. Autologous fat transplantation uses include the correction of body contour, malformations and post-surgical outcomes. The regenerative properties of ASCs allow treating damaged tissues such as wounds, burns, scars and radiodermatitis. The aim of this study was to perform a literature review highlighting the crucial role of adipose tissue in plastic and reconstructive surgery, from liposuction to lipofilling and ASCs, exposing the indications, procedures and complications of these surgical techniques.

Methods:

Literature review of publications concerning liposuction, lipofilling and adipose-derived stem cells (ASCS).

Results:

The introduction of liposuction allowed the use of adipose tissue for many clinical uses. The adipose tissue filling properties have been highlighted by the advent of lipofilling. The regenerative properties evidence of autologous fat transplantation encouraged the research on the clinical use of ASCs.

Conclusions:

Adipose tissue is not only the main energy storage of our body but also an important source of stem cells that can be used in various fields of regenerative medicine and tissue engineering with encouraging results for the future. (www.actabiomedica.it)

Minimizing the Short-term Reoperation Rate in Abdominoplasty Procedures by Prolonged Postoperative Immobilization

BACKGROUND

Abdominoplasty is a common procedure in postbariatric surgery. Over the years, a high number of technical refinements of the procedure have been established to improve safety and reduce associated complications. Nevertheless, the complication rate is high. The purpose of this study was to examine the incidence of postoperative complications in patients undergoing abdominoplasty in association with prolonged postoperative immobilization.

METHODS

Retrospective analysis of 82 patients who underwent abdominoplasty was performed. Patients were divided in two study groups regarding their immobilization period. Group 1 included patients with an immobilization period defined as strict bed rest for at least 45 h after surgery. Group 2 included all patients with shorter immobilization time, but earliest mobilization in the evening on the day of surgery.

RESULTS

Overall, complication rate was 27%. Major complications were observed in 15% in group 1 and in 23% in group 2. Hematoma requiring surgical revision was observed in 5% in group 1 and in 14% in group 2. Surgical revisions within the first 60 days were necessary in 5% in group 1 and in 20% in group 2.

CONCLUSION

Prolonged immobilization after abdominoplasty does not crucially lower the overall complication rate, but influences the severity of complications in a positive way. Increasing the duration of postoperative immobilization up to 45 h after abdominoplasty significantly decreases the reoperation rate in our practice. The risk for a surgical revision is nearly four times higher if the patient leaves bed earlier. Surgeons should consider this option especially in patients with a high risk for complication development.

The science behind autologous fat grafting

INTRODUCTION

Adipose grafting has undergone significant changes over time. Many different techniques have been followed by trying to improve the quality of the lipoaspirate and the survival of the fat graft after implantation.

MATERIAL AND METHODS

The purpose of this review is to analyse the historical evolution of the surgical harvesting and implant technique, describing the changes that have brought significant improvements, revolutionizing the aesthetic and functional results obtainable.

RESULTS

A standard fat grafting technique is commonly performed in three stages: harvesting of adipose tissue from a suitable donor site; processing of the lipoaspirate to eliminate cellular debris, acellular oil and excess of infiltrated solution, reinjection of the purified adipose tissue. The most widely used surgical technique was described by Coleman. He modified and corrected the methods and results of his predecessors and proposed an atraumatic protocol for the treatment of adipose tissue.He reported that the key to successful fat grafting lies in the technique. In addition, he noticed that adipose tissue was not only a good filler, but improved the quality of the skin. In fact, fat grafts demonstrated to have not only dermal filler properties but also regenerative potential owing to the presence of stem cells in fat tissue.

CONCLUSION

Adipose tissue, actually, is the closest to the ideal filler because it is readily available; easily obtainable, with low donor-site morbidity; repeatable; inexpensive; versatile; and biocompatible. There is an abundance of literature supporting the efficacy of fat grafting in both aesthetic and reconstructive cases. Recent studies have shown the utility of adipose-derived stem cells in the improvement of wound healing, describing their ability to regenerate soft tissues and their remodelling capacity provided by their unique cytokine and growth factor profiles.Despite ongoing concerns about survival and longevity of fat grafts after implantation and unpredictability of long-term outcome, fat has been successfully used as a filler in many differ clinic situation.

A journey through liposuction and liposculture: Review

INTRODUCTION

Nowadays, liposuction is the most frequently performed aesthetic surgery procedure in Western Countries. This technique has had rapid development since the 1970s, when it was experimented for the first time by A. and G. Fischer. It is currently widely used in clinical practice for many different situations in aesthetic, reconstructive and functional fields.

MATERIALS AND METHODS

This review aims to describe the historical evolution of liposuction by analyzing the transformation of the method in function of the introduction of innovative ideas or instruments. We have also focused on reporting the major clinical applications of this surgical technique, applicable to almost the entire body surface. We finally analyzed the complications, both major and minor, associated with this surgical technique.

RESULTS

Liposuction is mainly used to correct deep and superficial fat accumulations and remodel the body contour. It has become an essential complementary technique to enhance the aesthetic result of many other aesthetic procedures such as reduction mammoplasty, abdominoplasty, brachioplasty, thigh lift and post bariatric body contouring. However, it can be largely used for the treatment of innumerable pathologies in reconstructive surgery such as lipomas, lipedema, lipodystrophies, pneudogynecomastia and gynecomastia, macromastia e gigantomastia, lymphedema and many others. The complication rate is very low, especially when compared with conventional excisional surgery and the major, complications are generally associated with improper performance of the technique and poor patient management before and after surgery.

CONCLUSION

Liposuction is a safe, simple and effective method of body contouring. It has enormous potential for its application in ablative and reconstructive surgery, far from the most common aesthetic processes with a very low complication rate.

Quality of life and scar evolution after negative pressure or conventional therapy for wound dehiscence following post-bariatric abdominoplasty

No studies have examined scars and quality of life after different treatments of wound dehiscence in patients undergoing post-bariatric abdominoplasty. Scars and quality of life of patients with postoperative wound dehiscence managed with negative pressure wound therapy (group A) and conventional wound therapy (group B) were reviewed 6 months after wound healing. Of 38 patients undergoing treatment for wound dehiscence after 203 abdominoplasty, 35 (group A = 14 versus group B = 21) entered the study. Wound healing in group A was significantly faster than group B (P = 0·001). Patients (P = 0·0001) and observers (P = 0·0001) reported better overall opinions on a scar assessment scale for group A. Better overall quality of life and general health satisfaction were observed in group A (P < 0·05). A significant correlation was observed between the World Health Organization Quality of Life scores and Patient and Observer Scar Assessment Scale scores (r=-0·68, P < 0·0001) in all 35 patients. Negative pressure wound therapy is feasible and effective in patients with wound dehiscence following post-bariatric abdominoplasty. An adequate post-treatment outcome is achieved compared with conventional wound therapy in light of a strong association found between worse patient scar self-assessment and poor overall quality of life, regardless of the received treatment.

Efficacy of Autologous Platelet-rich Plasma Glue in Weight Loss Sequelae Surgery and Breast Reduction: A Prospective Study

Background:

Seroma and hematoma formations are the most common complications after plastic surgery. The aim of this study was to assess the efficacy of autologous platelet-rich plasma (A-PRP) glue to reduce postoperative wound complications and improve surgical outcomes.

Methods:

Fifty-four patients were included in this study. They underwent breast reduction surgery, abdominoplasty, or limb lifting with A-PRP glue application on the entire surface of the subcutaneous tissue at the time of suture. Retrospective data were used for the control group. The primary endpoint was the incidence of postoperative seroma or hematoma. The secondary endpoint was the Patient and Observer Scar Assessment Scale score.

Results:

Demographics and clinical characteristics were not statistically different between the A-PRP glue group and the control group regarding age, sex ratio, and body mass index. After abdominoplasty, 37.5% of patients (3/8) in the control group experienced seroma and hematoma complications versus 12.5% of patients (2/16) in the A-PRP glue group (P = 0.55 and P = 0.25, respectively). After limb lifting, 50% of patients experienced postoperative complications in the control group versus no patient in the A-PRP glue group (P = 0.03*; * indicates that the P value is significant). After breast reduction, no patient experienced complication in the A-PRP glue group versus 25% of patients in the control group who experienced hematoma (P = 0.04*). The scar quality assessed 12 months after surgery showed no statistical differences between the groups.

Conclusions:

A-PRP glue seems effective to prevent seroma formation after limb lifting and hematoma formation after breast reduction. Wound-healing quality did not seem to be improved.

The Effect of Body Mass Index on Outcome of Abdominoplasty Operations

BACKGROUND

Increased body mass index (BMI) increase the incidence of seroma formation and wound infection rates and subsequently increases wound dehiscence and ugly scar formation following abdomenoplasty and body contour surgery and also many other aesthetic and plastic surgery. The aim of this study was to determine the effect of BMI on the outcome of abdominoplasty operation.

METHODS

We carried out a prospective study of all patients who underwent abdominoplasty at our institution. Patient were divided into two groups. Group I were subjects with body mass index <30 kg/m2 while group II were patients with body mass index >30 kg/m2. Demographics and complications (minor and major) were recorded.

RESULTS

Sixty seven patients were enrolled. Group I were 32 patients with a mean age of 35.71 and group II 35 patients with mean age of 36.26 years. Seroma formation, wound complications, prolonged hospital stay and complications were significantly more in group II.

CONCLUSION

We found that increased BMI significantly increased operative time, hospital stay, drainage duration and drainage amount. Our findings showed that obesity alone could increase the incidence of complications and poor outcome of abdominoplasty.

Improvements in Vertebral-Column Angles and Psychological Metrics After Abdominoplasty With Rectus Plication

BACKGROUND

Substantial fluctuations in body weight can result in diastasis recti and weakening of the connections between the lateral abdominal muscles and the rectus sheath.

OBJECTIVES

The authors sought to determine the postural and psychological effects of abdominoplasty with vertical rectus plication.

METHODS

Forty women with substantial back and lumbar pain owing to abdominal lipodystrophy were evaluated in a prospective study. Preoperatively and 6 months postoperatively, patients underwent bidirectional radiography of the thoracic and lumbar regions. A visual analog scale (VAS), the Beck Depression Inventory (BDI), and the Nottingham Health Profile (NHP) were applied to assess physical, psychological, and quality-of-life changes following surgery.

RESULTS

Significant improvements in posture, assessed in terms of lumbar lordosis, thoracic kyphosis, and the lumbosacral angle, were observed 6 months after abdominoplasty with rectus plication. Results of the VAS and BDI indicated significant improvements in pain and quality of life, respectively. Results of the NHP indicated significant postoperative improvements in fatigue, pain, and sleep.

CONCLUSIONS

Abdominoplasty with rectus plication improves posture by tightening the thoracolumbar fascia. In selected patients, abdominoplasty can reduce back and lumbar pain, thereby improving quality of life.
