Abdominoplasty: a comparison of outpatient and inpatient procedures shows that it is a safe and effective procedure for outpatients in an office-based surgery clinic

Abdominoplasty after massive weight loss. Safety preservation fascia technique and clinical outcomes in a large single series-comparative study

Introduction

Weight loss after bariatric surgery causes very important modifications to the patient's silhouette. Abdominal fat and skin excess reduction are associated with several complications. The most frequent are seroma and hematoma whereas major complications, such as pulmonary embolism, are less frequent. This study aimed to describe our technical procedure for abdominoplasty in patients with massive weight loss after bariatric surgery.

Methods

In total, 196 patients were included. All patients who underwent abdominoplasty classic (group A) and abdominoplasty with the preservation and lift of Scarpa fascia (group B) and with umbilical transposition between May 2018 and May 2021 were included. Patients with concomitant correction of ventral hernia were excluded. Demographic and operative data were analyzed according to comorbidities and postoperative complications.

Results

There were 160 (81.6%) women. The mean age was 43.6 years; the mean weight was 86.7 kg; and the mean BMI was 28.6 kg/m2. Five patients (2.5%) presented postoperative seroma. Four patients (2%) presented partial dehiscence/skin necrosis one of them requiring a revision. Finally, 26 patients presented a postoperative complication, with an overall incidence of 12.6%. The average postoperative hospital stay was 3.6. The rates of seroma were significantly higher in men, patients with a BMI > 30 kg/m2, and aged >50 years.

Conclusion

Preserving Scarpa Fascia during surgical post-bariatric patient procedures reduces the seroma formation and the scar complication and reduces the tension of the inguinal-pubic region with correction of our deformation after weight loss. Improves reducing the drain and reducing seroma incidence suction and hospital stay.

Safety and Efficacy of Outpatient Drainless Abdominoplasty: A Single-Surgeon Experience of 454 Consecutive Patients

BACKGROUND

The incidence of seroma after abdominoplasty is accepted as approximately 10% (with a range) in the literature. Progressive tension sutures (PTS) have arisen as a means of reducing seroma, however there are conflicting data regarding their efficacy.

OBJECTIVES

The primary aim of this study was to describe the incidence of postabdominoplasty seroma in the setting of drainless abdominoplasty with PTS.

METHODS

A retrospective chart review was performed of all abdominoplasties (n = 454) during a 20-year period. At approximately the halfway point of this time frame, the abdominoplasty technique was changed from the use of 2 drains to the use of PTS without drains. Additionally, pulsed electromagnetic field therapy (PEMF) and liposomal bupivacaine (Exparel, Pacira Pharmaceuticals, Inc., Parsippany, NJ) were added as pain control adjuncts.

RESULTS

There were 194 patients in the drain group and 260 patients in the PTS/no drains group. The group without drains contained a significantly higher proportion of massive weight loss patients (4.1% vs 9.2%, P = .041). The majority of the group without drains underwent outpatient surgery (89.7% vs 98.8%, P < .001). The overall complication rate was significantly lower in the no drains group (31.4% vs 13.8%, P < .001). The incidence of seroma was dramatically reduced in the group without drains (24.7% vs 0.0%, P < .001).

CONCLUSIONS

PTS are highly effective in preventing seroma and can be safely employed as an alternative to drains in abdominoplasty. PEMF may play a role in seroma prevention and is also helpful for pain control. With these techniques to mitigate complications and minimize postoperative pain, abdominoplasty can be performed safely and effectively in a purely outpatient setting.

Comparing seroma formation rate after harvest of the deep inferior epigastric artery perforator flap and the superficial abdominal perforator flaps in autologous breast reconstruction: A propensity-matched analysis

BACKGROUND

Donor site seroma formation and prolonged drainage duration are commonly seen after harvest of perforator-based abdominal flaps. The lymphatic network including the lymphatic vessels and the lymph nodes can be traumatized during harvest of a perforator-based abdominal flap, eventually causing seroma formation. The aim of this study was to compare postoperative seroma occurrence rates between the deep system group including the deep inferior epigastric artery perforator (DIEP) flap and the superficial system group comprised of the superficial inferior epigastric artery (SIEA) flap, the superficial circumflex iliac artery perforator (SCIP) flap, and the SIEA-SCIP combined flap.

PATIENTS AND METHODS

A retrospective analysis of all patients who underwent unilateral breast reconstruction using perforator-based abdominal flaps from June 2020 to May 2021 was performed. The patients were divided into the deep system group and the superficial system group. Propensity score matching was used to compare in the two groups the mean duration of drainage in the donor site and the occurrence of postoperative aspiration. Covariates included sex, age, body mass index, history of smoking, past history of diabetes mellitus. One hundred and fifteen patients (the deep system group, n = 100 and the superficial system group, n = 15) met inclusion criteria for a 1:1 match performed on 14 deep system group patients using propensity scores, with 14 superficial system group patients having similar characteristics.

RESULTS

The mean duration of drainage in the donor site was shorter in the deep system group (6.6 ± 1.9 days) than in the superficial system group (9.3 ± 2.3 days, p < .01). The occurrence rate of postoperative aspiration was lower in the deep system group (0%) than in the superficial system group (50%, p < .01).

CONCLUSIONS

Although superficial abdominal perforator flaps are considered to be less invasive than the DIEP flap, they are associated with prolonged donor site drainage and more frequent occurrence rate of postoperative aspiration.

Optimizing Nonopioid Analgesia and Different Pain Management Options following Abdominoplasty: A Systematic Literature Review

Introduction

Postoperative pain remains a significant challenge with the growing number of abdominoplasties every year. Opioids are currently considered the mainstay modality for controlling postoperative pain. However, opioid-related side effects raise the need for a safer and more effective approach. In this study, we aimed to investigate these alternative evidence-based postoperative pain relief modalities following abdominoplasty.

Methods

This systematic review was designed and conducted using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The literature was systematically searched in December 2021 using the following databases: MEDLINE, Cochrane, and EMBASE. The MeSH terms used to aid the search were the following: abdominoplasty, postoperative pain management, postoperative analgesia, pain control, analgesia, and pain.

Results

Reviewing the literature resulted in a total of 851 publications. After implementing our criteria, only 13 articles were included in this study, with 990 patients. A continuous infusion pump was the most commonly used method of analgesia (n = 3), followed by a transversus abdominis plane block (n = 2). The postoperative pain assessment scale was mentioned in nine out of the 13. Compared to controls, all interventions resulted in considerably lower pain levels in all the patients. Patient satisfaction was reported in three studies, and all studies reported higher satisfaction rates than the control groups.

Conclusions

The authors performed a systematic review of the existing database of high-quality research on pain management after cosmetic abdominoplasty to determine the best pain management options currently available. However, future studies are recommended to assess the optimum dosing and administration methods.

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.

Local Triamcinolone Treatment Affects Inflammatory Response in Seroma Exudate of Abdominoplasty Patients: A Randomized Controlled Trial

BACKGROUND

As the leading complication of abdominoplasty, seroma formation might represent an inflammatory process in response to surgical trauma. This prospective randomized trial investigated whether local administration of the antiinflammatory agent triamcinolone could prevent seroma accumulation.

METHODS

Weekly and cumulative seroma volumes were compared between the study groups A, B, and C over a 4-week follow-up (group A, with drain, without triamcinolone; group B, without drain, without triamcinolone; group C, without drain, with triamcinolone). Aspirated seroma samples were analyzed by enzyme-linked immunosorbent assay for selective inflammatory mediators.

RESULTS

Triamcinolone significantly reduced cumulative seroma volume (n = 60; mA 845 ± SDA 578 ml, mC 236 ± SDC 381 ml, p = 0.001). The most accentuated suppressive effect of triamcinolone was observed shortly after the treatment (week 1) (mA1 616 ± SDA1 457 ml, mB1 153 ± SDB1 161 ml, mC1 22 ± SDC1 44 ml, pA1/C1 < 0.001, pB1/C1 = 0.014). Local triamcinolone administration resulted in a differential concentration of interleukin-6 (IL-6) and matrix metalloproteinase-9 (MMP-9 (week 1) in seroma exudate as measured by enzyme-linked immunosorbent assay (mIL-6A1 1239 ± SDA1 59 pg/ml, mIL-6C1 848 ± SDC1 80 pg/ml, p < 0.001; mMMP-9A1 2343 ± SDA1 484 pg/ml, mMMP-9C1 376 ± SDC1 120 pg/ml, p = 0.001).

CONCLUSIONS

Local administration of 80 mg of triamcinolone reduced postabdominoplasty seroma accumulation significantly. Under triamcinolone treatment, suppressed levels of IL-6 and MMP-9 in seroma fluid were observed. Notably, inflammatory marker suppression correlated clinically with a decrease in seroma accumulation.

The Addition of Partial or Circumferential Liposuction to Abdominoplasty Is Not Associated With a Higher Risk of Skin Necrosis

BACKGROUND

Combining abdominoplasty with liposuction is a common practice for optimal patient aesthetic outcomes. In the past, several practitioners have argued against liposuction due to the potential for vascular insufficiency, especially with central liposuction. Despite these concerns for flap damage with resultant necrosis, the incidence of this complication has not been comprehensively investigated.

OBJECTIVES

The authors therefore examined the incidence of necrotic complications, including skin and fat necrosis as well as partial/total flap loss, in patients who underwent abdominoplasty alone (AA) or abdominoplasty with partial or circumferential liposuction (APCL).

METHODS

Literature searches were performed in PubMed/Medline and Embase with no query limits. For the systematic review, data from the studies were extracted into a form including primary author, publication year, study design, number of AA and APCL patients, abdominal zone(s) treated with liposuction, average lipoaspirate volume, follow-up time, necrotic complications, and revision procedures. A meta-analysis was separately performed for 13 studies that included patients who underwent both AA and APCL.

RESULTS

The overall rate of necrotic complications was lower in the APCL group (0.39%) compared with the AA group (1.01%). The incidence of necrotic complications was low for all patients, with a pooled partial flap loss rate of 0.24% and a pooled skin necrosis rate of 0.23%. The forest plots revealed that patients who underwent APCL do not face a higher risk of skin necrosis or revision compared with those who underwent AA.

CONCLUSIONS

Performing APCL is a safe combined procedural approach and can confer added benefits of improved patient satisfaction and aesthetic outcomes.

Surgical Site Infections in Aesthetic Surgery

Surgical site infections represent one of the most common postoperative complications in patients undergoing aesthetic surgery. As with other postoperative complications, the incidence of these infections may be influenced by many factors and varies depending on the specific operation performed. Understanding the risk factors for infection development is critical because careful patient selection and appropriate perioperative counseling will set the right expectations and can ultimately improve patient outcomes and satisfaction. Various perioperative prevention measures may also be employed to minimize the incidence of these infections. Once the infection occurs, prompt diagnosis will allow management of the infection and any associated complications in a timely manner to ensure patient safety, optimize the postoperative course, and avoid long-term sequelae.

Abdominoplasty with Circumferential Liposuction: A Review of 1000 Consecutive Cases

BACKGROUND

The authors present the technique called "abdominoplasty with concurrent circumferential liposuction," where the whole trunk is addressed as a single aesthetic unit.

METHODS

Between January of 2008 and June of 2016, abdominoplasty with circumferential liposuction was performed in 1000 patients (984 women and 16 men) by the senior author. Patients had a mean body mass index of 27.5 kg/m (range, 18.1 to 34.5 5 kg/m). Liposuction was performed circumferentially and the abdominal flap was detached up to the costal margins. Simultaneous fat grafting was also performed if required. Outcomes and complications were documented.

RESULTS

Traditional abdominoplasty incisions were used in 359 patients, whereas extended incisions were used in 641 patients. The mean duration of follow-up was 27 months (range, 12 days to 61 months), and the mean duration of surgery was 154 minutes (range, 109 to 260 minutes). The mean amount of simultaneously aspired supernatant lipoaspirate was 1940 cc (range, 1700 to 4580 cc). Simultaneous gluteal fat grafting was performed in 34 percent. None of the patients had any skin necrosis. The most common complication was seroma (19 percent).

CONCLUSIONS

In abdominoplasty, the entire central body should be considered as a single unit. Circumferential widespread liposuction with standard undermining of the abdominal flap up to the costal margins is safe and yields superior aesthetic outcomes.

An Update on the Safety and Efficacy of Outpatient Plastic Surgery: A Review of 26,032 Consecutive Cases

BACKGROUND

Outpatient surgery offers many advantages, including cost-containment, privacy, and convenience. However, patient safety must take precedence over these benefits. Limited well-designed studies exist in the plastic surgery literature on patient safety in the outpatient setting, particularly those that identify risk factors for adverse outcomes.

METHODS

A retrospective review was performed on 26,032 consecutive cases completed by board-certified plastic surgeons at an accredited outpatient surgical center between 1995 and 2017. All cases were reviewed for potential morbidity and mortality events, and variables were analyzed to determine potential risk factors for postoperative complications and inpatient admission.

RESULTS

A total of 26,032 cases were performed over a 23-year period. There were a total of 203 complications (0.78 percent). Compared with the control population, the 12 patients (0.05 percent) that sustained venous thromboembolic events demonstrated higher body mass indexes (p < 0.01), greater lipoaspirate amounts (p = 0.04), longer operative times (p < 0.01), and were more likely to have undergone a combined procedure (p < 0.01). In addition, the 22 patients (0.08 percent) that were transferred to inpatient facilities demonstrated greater body mass index (p < 0.01) and longer operative times (p = 0.01).

CONCLUSIONS

Plastic surgery is safe to perform in an accredited outpatient facility for a majority of patients. According to the authors' data, postoperative monitoring in a nursing facility should be considered for the following high-risk patients: those with a body mass index greater than 30 kg/m, operative times greater than 4 hours, lipoaspirate volumes greater than 3 liters, and those undergoing combined procedures.

Classic high lateral tension and triangular resection methods to prevent dog ear and elongation scar in patients undergoing abdominoplasty: A comparative open-label clinical trial

Background:

One of the most common operations in the plastic surgery curse is abdominoplasty. Several methods were recommended for achieving better results. In the present study, efficacy of a new method compared with classical high lateral tension on preventing dog ear and elongation scar was evaluated.

Materials and Methods:

in an open-label, randomized clinical trial, seventy patients who were candidates for abdominoplasty were selected and randomly divided into two groups. The first group was operated by classic high lateral method and the second group was operated by a new method concentrating on changing incision line and angle. Dog ear prevention, length of scar, improvement, and postoperative complications were compared between the two groups.

Results:

The mean ± standard deviation (SD) length of scar in treated patients with classical and new abdominoplasty surgical methods was 53.68 ± 6.34 and 41.71 ± 1.78 cm, respectively, and the length of scar in the group treated with the new method was significantly shorter (P < 0.001). The mean ± SD distance between two anterior superior iliac spine in group treated by new method was significantly decreased after surgery (31.3 ± 1.3 cm) compared to before intervention (36.7 ± 3.9 cm) (P < 0.01).

Conclusion:

The new method is more likely to be successful in patients with high lateral tension abdominoplasty. However, according to the lack of similar studies in this regard and the fact that this method was introduced for the first time, it is recommended that further studies in this area are needed and patients in term of complications after surgery need a longer period of follow-up.

Operative correction of abdominal rectus diastasis (ARD) reduces pain and improves abdominal wall muscle strength: A randomized, prospective trial comparing retromuscular mesh repair to double-row, self-retaining sutures

BACKGROUND

The primary aim of this prospective, randomized, clinical, 2-armed trial was to evaluate the risk for recurrence using 2 different operative techniques for repair of abdominal rectus diastasis. Secondary aims were comparison of pain, abdominal muscle strength, and quality of life and to compare those outcomes to a control group receiving physical training only.

METHODS

Eighty-six patients were enrolled. Twenty-nine patients were allocated to retromuscular polypropylene mesh and 27 to double-row plication with Quill technology. Thirty-two patients participated in a 3-month training program. Diastasis was evaluated with computed tomography scan and clinically. Pain was assessed using the ventral hernia pain questionnaire, a quality-of-life survey, SF-36, and abdominal muscle strength using the Biodex System-4.

RESULTS

One early recurrence occurred in the Quill group, 2 encapsulated seromas in the mesh group, and 3 in the suture group. Significant improvements in perceived pain, the ventral hernia pain questionnaire, and quality of life appeared at the 1-year follow-up with no difference between the 2 operative groups. Significant muscular improvement was obtained in all groups (Biodex System-4). Patient perceived gain in muscle strength assessed with a visual analog scale improved similarly in both operative groups. This improvement was significantly greater than that seen in the training group. Patients in the training group still experienced bodily pain at follow-up.

CONCLUSION

There was no difference between the Quill technique and retromuscular mesh in the effect on abdominal wall stability, with a similar complication rate 1 year after operation. An operation improves functional ability and quality of life. Training strengthens the abdominal muscles, but patients still experience discomfort and pain.

An alternative outpatient care model: postoperative guest suite-based care

BACKGROUND

Patients recovering from outpatient surgery are responsible for managing their pain, managing ambulation, and even implementing thromboembolism prophylaxis after discharge. Because of the importance of postoperative care to prevent complications, a model of care that helps a patient transition to independent self-care could provide optimal results.

OBJECTIVES

The authors investigated the safety and morbidity rate for patients who underwent body contouring procedures and overnight care at an attached, nurse-staffed guest suite facility.

METHODS

A retrospective review was conducted of 246 patients who underwent major body contouring and who stayed at least 1 night in the guest suite facility. Major complications included a return to the operating room within 48 hours, major wound infection, and unplanned hospitalization within 48 hours. Minor complications included any postsurgical effect necessitating unplanned physician intervention within the first 30 days. Univariate analyses correlating patient characteristics and complication rates were conducted, as well as comparison of complication rates among same procedures reported in the literature.

RESULTS

The complication rate (major and minor complications) was 25.20%. Surgical site infection occurred in 8.13% of patients. The most common wound complication was erythema around the incision site (12.20%). Death, deep vein thrombosis, or pulmonary embolism did not occur. Comparison with relevant results reported in the literature indicated a significant reduction in the occurrence of postoperative venous thromboembolism.

CONCLUSIONS

Patient education after surgery is essential to healing and adequate care. The guest suite model provides improved care and education for the patient and family postsurgery by addressing some of the known risk factors of plastic surgery.

Prospective clinical study of 551 cases of liposuction and abdominoplasty performed individually and in combination

BACKGROUND

Despite the popularity of these procedures, there are limited published prospective studies evaluating liposuction and abdominoplasty. Lipoabdominoplasty is a subject of recent attention. Several investigators have recommended alternative techniques that preserve the Scarpa fascia in an effort to reduce complications, particularly the risk of seromas.

METHODS

Over a 5-year period, 551 consecutive patients were treated with ultrasonic liposuction alone (n = 384), liposuction/abdominoplasty (n = 150), or abdominoplasty alone (n = 17). In lipoabdominoplasties, the abdomen and flanks were first treated with liposuction. A traditional flap dissection was used for all abdominoplasties. Scalpel dissection was used rather than electrodissection. A supine "jackknife" position was used in surgery to provide maximum hip flexion, allowing a secure deep fascial repair.

RESULTS

The complication rate after liposuction was 4.2% vs 50% for patients treated with an abdominoplasty. Approximately half of the abdominoplasty complications were minor scar deformities, including widened umbilical scars (17.3%) that were revised. The seroma rate after abdominoplasties was 5.4%; there were no seromas after liposuction alone.

CONCLUSIONS

Lipoabdominoplasty may be performed safely, so that patients may benefit from both modalities. The seroma rate is reduced by avoiding electrodissection, making Scarpa fascia preservation a moot point. A deep fascial repair keeps the abdominoplasty scar within the bikini line. Deep venous thrombosis and other complications may be minimized with precautions that do not include anticoagulation.

Glucose concentration in seromas after plastic surgery: a pilot study

Previously, glucose concentration has been presumed to be similar in seroma, lymph, and plasma. However, there are few studies actually measuring glucose concentration in seroma. The aim of this pilot study was to determine if the glucose concentration in seroma is similar to that in plasma, as it has previously been presumed. Biochemical analysis of seroma was performed on 11 patients that had undergone plastic surgery. Fluid was taken from the drains between postoperative day 3 and 6. The median glucose concentration was 3.09 millimolar (mM) (range 2.25-3.89 mM). Glucose concentration in seroma does not seem to be similar to that of plasma and lymph that has previously been presumed. The result of this pilot study warrants further investigation to determine the span of normal glucose concentration, its development over time, its relation to plasma glucose concentration, and how it is affected by infection.

Outpatient-based massive weight loss body contouring: a review of 260 consecutive cases

BACKGROUND

Massive weight loss (MWL), whether from bariatric surgery or self-directed efforts, has become an increasingly-frequent reason for which patients present for body-contouring procedures. As the incidence of post-MWL surgery has increased, there has also been an increase in the frequency of outpatient ambulatory techniques for complex procedures.

OBJECTIVES

The author describes his experience with MWL body contouring in an outpatient setting.

METHODS

A retrospective review was performed of 260 consecutive patients who presented to the author's clinic for post-MWL body contouring in the author's accredited outpatient clinic. Many patients (n=150) underwent concurrent operations, for a total of 544 procedures. All patients received general anesthesia delivered by a board-certified anesthesiologist, received rigorous perioperative education, and were discharged on the day of operation.

RESULTS

Of the 260 patients, 241 were women and 19 were men. The average patient age was 42 years (range, 19-70 years). Among the 544 procedures, the most common complication was minor wound separation. There were no wound infections and only one pulmonary embolism. There were no hospital readmissions and no deaths.

CONCLUSIONS

With judicious patient selection, standardized perioperative teaching, and appropriate anesthesia, practitioners' advanced knowledge about complex MWL operations can allow them to perform these procedures safely and effectively in an accredited outpatient setting.

DIEP flap donor site versus elective abdominoplasty short-term complication rates: a meta-analysis

BACKGROUND

Although over the past decade the DIEP flap has emerged as one of the preferred choices for autologous breast reconstruction and the donor-site closure has much in common with the standard abdominoplasty technique, reports on comparisons of the complication rates between DIEP and elective abdominoplasty patients are not currently available. The purpose of this study was to compare DIEP donor-site and elective abdominoplasty short-term complications rates, in support of surgical choices.

METHODS

Searches of MEDLINE and CENTRAL for English language articles on DIEP and elective abdominoplasty (EA) published from January 1999 through December 2009 identified 33 studies that met the inclusion criteria and included 3,937 patients. A random-effects model was used to calculate the average complication rate in the literature.

RESULTS

The rate of seroma/hematoma in EA (16.1%, 95% confidence interval [CI] = 12.2-20.9%) was approximately four times the rate in DIEP flap patients (3.7%, 95% CI = 1.5-8.8%) was found from analyzing the data under a random-effects model. No substantial differences in the rates of infection, abdominal/umbilical necrosis, or wound dehiscence/delayed healing between the two series of patients were detected.

CONCLUSIONS

This meta-analysis reveals that DIEP donor-site complication rates were comparable to those in elective abdominoplasty, and, the rate of seroma in DIEP is an even lower than that of one of the most performed procedures in plastic surgery. We argue that patients presenting for a DIEP flap should be informed about this interesting comparison.

Venous thromboembolism in abdominoplasty: a comprehensive approach to lower procedural risk

BACKGROUND

Venous thromboembolism (VTE) is a serious and potentially life-threatening surgical complication. However, there is little consensus regarding appropriate VTE prophylaxis for plastic surgery patients. Risk factors as they apply to plastic surgery patients are unclear, and recent recommendations for chemoprophylaxis in these patients may expose them to other additional risks.

OBJECTIVES

The authors examine perioperative and intraoperative measures, specifically those that have enabled a large number of patients to undergo outpatient abdominoplasty safely, with a reduced risk of VTE.

METHODS

A retrospective review was performed of 404 consecutive abdominoplasty patients who were treated at a single outpatient surgery center between 2000 and 2010. Graded compression stockings and intermittent pneumatic compression devices were placed on all patients, and perioperative and intraoperative warming was strictly applied. Progressive tension suturing technique was performed in all cases and drains were eliminated. All patients received pain pumps, ambulated within one hour of surgery, and were discharged home the same day. Patient VTE risk factors were scored with the Caprini/Davison risk assessment model (RAM). Perioperative and intraoperative measures were taken to reduce factors that may increase VTE risk in abdominoplasty. Complications were recorded, including VTE events, seromas, hematomas, and infections.

RESULTS

In this series, 247 abdominoplasty procedures were performed alone and 157 were combined with additional procedures. Under the RAM, 297 patients were considered "high risk" and 17 "highest risk." Abdominoplasty operative time was 100 ± 29 minutes. Only one case of deep vein thrombosis (DVT) occurred, in the calf.

CONCLUSIONS

A comprehensive approach to perioperative and intraoperative patient care has allowed outpatient abdominoplasty to be safely performed without VTE chemoprophylaxis in patients with fewer than six risk factors.

Umbilical epithelial cyst in secondary abdominoplasty: case report

BACKGROUND

A retained epidermal inclusion cyst (REIC) at the umbilicus after abdominoplasty is a rare phenomenon that has had limited description in the literature. This case report describes a woman who came for a secondary abdominoplasty and presented intraoperatively with an unexpected large epidermal inclusion cyst.

CASE REPORT

The woman was disappointed with the result of a previous abdominal surgery. She initially had severe postoperative wound infection followed by revision surgery and subsequent intermittent secretion in the umbilical region. Then seven years later, hip backplasty combined with liposuction was performed. After another six months, full abdominoplasty combined with exploration of the umbilical region was performed. The surgical exploration showed a large, 3×4.5 cm indurated structure highly suspected to be a REIC. The excision was effective without recurrence, and the healing was uneventful. The patient was very satisfied with the result.

DISCUSSION

As a typical epidermoid cyst, REIC consists of squamosed stratified epithelial cells that continue to the granular layer. In most cases, the cyst is filled with a keratin-like material. When this tumor is solid, a histologic evaluation may be necessary. When the cyst has been excised, the umbilicus gets reconstructed after the abdominoplasty. A history of poor healing in the umbilicus area may arouse suspicion of an epidermoid cyst. Epidermoid cysts in the region of the umbilicus could easily be overlooked in preparation of the umbilicus.

Safety in office-based full abdominoplasty

BACKGROUND

As demand for outpatient procedures has increased, abdominoplasties are now judiciously being performed in accredited outpatient facilities. Previous reports on outpatient abdominoplasties are limited by small cohorts and have not distinguished among different types of body contouring procedures. Furthermore, these reports included patients who remained in the hospital overnight, rather than patients who were discharged within hours postoperatively.

OBJECTIVES

The authors review a case series of patients who underwent full abdominoplasty procedures performed in an outpatient facility with same-day discharge.

METHODS

Charts were retrospectively reviewed for 319 consecutive patients who underwent full abdominoplasty with the senior author (CLM) between 1992 and 2010. The charts of 206 patients for whom complete electronic medical record data were available were analyzed as a separate cohort. Demographic, operative, and postoperative data were collected. Systemic and local complications were assessed, as were revision rates.

RESULTS

No patients in this series developed any systemic complications, including deep venous thrombosis or pulmonary embolism, blood transfusion, intra-abdominal perforation, or death. The most common local complication was seroma, at a rate of 19.4%.

CONCLUSIONS

This report serves to add to the literature a large cohort of patients who underwent full abdominoplasty and were discharged within hours of surgery. The study shows that full abdominoplasty procedures can be safely performed without systemic complications in an outpatient setting. Based on these data, the ever-present sentiment that abdominoplasty is the plastic surgery procedure associated with the highest rate of venous thromboembolism should be carefully evaluated.

Surgical site infections after post-bariatric abdominoplasty and flank liposuction: a case-control study focusing on the quantity of tissue removed

We evaluated whether the quantity of fat removed during abdominoplasty and liposuction correlated with the occurrence of surgical site infection (SSI). We selected patients of similar age, sex, smoking status, obesity, and post-bariatric weight loss, retrospectively, and classified them into groups according to the development of SSI. The total amount of fat removed and aspirated was compared. The size of the flap removed from the abdomen and the amount of fat aspirated with liposuction differed significantly between the SSI and no-SSI groups (1.6 ± 0.2 vs. 0.6 ± 0.3 kg and 2 ± 0.2 vs. 0.9 ± 0.3 l, respectively; p < 0.001). The four SSI patients with the most fat removed (1.4 ± 0.2 kg) or aspirated (2 ± 0.1 l kg) had the deepest infections. SSI was strongly correlated with the size of flap resection (ρ = 0.80; p < 0.001) and liposuction (ρ = 0.72; p < 0.001). The quantity of fat removed or aspirated can influence the occurrence of SSI. If confirmed, these data could be used to better stratify patients according to their risk.

Outcomes analysis of a resident cosmetic clinic: safety and feasibility after 7 years

Cosmetic patients have many options when seeking out their surgeons. In midsize and larger cities, these options span not only different specialties but also different levels of experience. Because surgical experience can best be gained first hand, there exists a special and symbiotic relationship between a surgeon-in-training and his or her patient. Benefits stem from the opportunity for a surgeon to gain independent experience while offering cost effective benefits to patients who may or may not otherwise have access to cosmetic surgery. To meet the needs of both patients and the surgeons-in-training, the Wake Forest University Plastic and Reconstructive Surgery Training Program has set up and maintained a chief resident run cosmetic surgery clinic for 17 years. Each chief resident serves as primary surgeon 1 day a week during the chief year. We present a 7-year retrospective outcome analysis of this experience. The authors performed an Institutional Review Board approved retrospective chart review of all patients who received major cosmetic procedures performed in the WFU chief resident clinic over a 7-year span from 2000 to 2007. A total of 210 charts were reviewed. Fourteen charts were excluded because of inadequate records or non esthetic procedures performed concomitantly. All procedures were viewed as independent events. A total of 196 patients underwent 272 procedures. All procedures were evaluated for major and minor complications and revisions. A total number of 272 initial cosmetic procedures were performed in a 7-year span. Adverse events were divided into major and minor complications. There were no major complications for any of the procedures. Overall minor complication rate was 8.0%. Overall revision rate was 14.4%. Procedures with greatest probability of revision were abdominoplasty and reduction mammaplasty. Chief resident clinics provide a unique experience wherein surgeons-in-training are allowed to hone previously developed surgical acumen while providing a safe and expectedly desirable result for their patients. Because many cosmetic patients desire secondary touch up procedures, a rate of 14.4% in this cohort is neither unexpected nor unacceptable. In addition, the postoperative evaluation and the decision to pursue secondary procedures provides a unique perspective to the chief residents. A chief resident run clinic can be an effective and safe learning tool, providing benefit to patient and the surgeon in training.

Prevention of seroma after abdominoplasty

BACKGROUND

Seroma is one of the most troubling complications after abdominoplasty; incidence rates of up to 25% have been reported. If it is correct that shearing forces between the two separated abdominal layers play a key role in the development of seroma, postoperative immobilization of the patient until the layers are sufficiently adhered may be a solution to the problem.

OBJECTIVE

The authors examine the association between length of immobilization and the development of seroma.

METHODS

This retrospective study included 60 patients; half were immobilized for 24 hours (group 1) and the other half were immobilized for at least 48 hours (group 2). For thromboembolism prophylaxis, all patients received low molecular weight heparin and compression stockings. Postoperative follow-up for detection of seroma continued for at least three months.

RESULTS

Mobilization after 24 hours led to a seroma rate of 13%, whereas immobilization of at least 48 hours decreased the seroma rate to 0%.

CONCLUSIONS

For abdominoplasty patients with a low or moderate thromboembolic risk, the data suggest that immobilization for at least 48 hours with chemical and mechanical thromboembolism prophylaxis significantly reduces the risk of seroma.

Reducing seroma in outpatient abdominoplasty: analysis of 516 consecutive cases

BACKGROUND

Over the past 30 years, the preferred techniques and settings for abdominoplasty have evolved considerably, but controversy remains regarding the surgical and postoperative approaches that best limit serious complications such as seroma.

OBJECTIVE

The authors evaluate their 28-year experience with abdominoplasty and suggest a technique (progressive tension sutures without placement of drains) for reducing the overall complication rate, most significantly with regard to seroma.

METHODS

A retrospective review was conducted of 517 consecutive abdominoplasty cases in the senior author's clinic. The cases were divided into five groups based on operative setting, postoperative care, and surgical technique. Concurrent procedures and complications were also reviewed.

RESULTS

The authors found that the last group of patients, in whom abdominoplasty with progressive tension sutures (but without drains) was performed as an outpatient procedure, had the lowest incidence of seroma. Specifically, the incidence of clinically significant seroma formation requiring aspiration was 9.6% in early groups, when abdominoplasty was performed as an inpatient procedure; the rate was 24% when it was performed as an outpatient procedure without the placement of progressive tension sutures, but was then reduced to 1.7% with the placement of progressive tension sutures and no drains.

CONCLUSIONS

Abdominoplasty can be safely performed with other concomitant procedures (such as liposuction) in a strictly outpatient setting when surgical time is limited. Despite controversy in the previous literature, the authors' data support the conclusion that the placement of progressive tension sutures without drains dramatically decreases overall complication and seroma rate during abdominoplasty.

Postbariatric patients undergoing body-contouring abdominoplasty: two techniques to raise the flap and their influence on postoperative complications

Postbariatric patients undergoing abdominoplasties were retrospectively analyzed to correlate postoperative local complications with the 2 most commonly used techniques of raising the abdominal flap: diathermocoagulation versus scalpel. All patients undergoing body-contouring abdominoplasties were included. Excluded were patients with ongoing clinical infections, those that received a complete course of antibiotic in the 6 months before operation, those requesting steroid therapy, those with systemic diseases that could impair wound repair (arteriosclerosis, diabetes mellitus), and those who had undergone apronectomy. One hundred thirty-seven patients were divided into 2 groups (diathermocoagulation = 90 vs. scalpel = 47). Overall, 7 seromas (5.1%), 7 hematomas (5.1%), and 28 wound infections (20.4%) were detected. A higher occurrence of postoperative hematomas was found after the flap raised using a scalpel (12.8% vs. 1.1%, Fisher exact test, P < 0.05), with a relative risk of 11.6. A significant association existed between postoperative hematomas and wound infections with delayed healing (n = 10, 7.3%): 43% of patients with a hematoma also experienced a wound infection with delayed healing versus 5.4% of those that did not develop hematomas (Fisher exact test; P < 0.01). In patients for whom a scalpel had been used to raise the flap, this correlation persisted (50% of patients with a hematoma had developed a wound infection with delayed healing vs. 7.3% of those that did not develop hematomas; Fisher exact test; P < 0.05).In postbariatric patients, diathermocoagulation reduces the occurrence of postoperative hematomas and wound infections with delayed healing compared with the cold knife.

Does Morbid Obesity Increase Morbidity in Abdominoplasty?

To determine whether morbid obesity increased morbidity in abdominoplasty 200 mostly female patients (100 patients morbidly obese and 100 overweight and obese) were studied but showed no statistically significant difference in the complication rate between the two categories nor between them and the international rate of complication of dermolipectomy in non-obese patients although co-morbid diseases did increase the risk of complications. It is concluded that morbid obesity should not preclude abdominoplasty, that patients do benefit, especially obese patients who are unable to lose weight following dieting or even gastric banding. surgery.

Wound infections in aesthetic abdominoplasties: the role of smoking

BACKGROUND

In this prospective study, the authors followed patients who underwent aesthetic abdominoplasty to determine the influence of smoking on the occurrence of postoperative wound infections.

METHODS

Patients who underwent aesthetic abdominoplasty were considered eligible for the study. The authors excluded postbariatric patients, those with ongoing clinical infections, those receiving a recent antibiotic course, and those with systemic diseases such as arteriosclerosis and diabetes mellitus. Smokers were advised to quit smoking at least 4 weeks before surgery.

RESULTS

Starting in February of 2004, the authors enrolled 84 patients. Postoperative infections were present in 13 patients (15.5 percent) and were superficial in 10 (77 percent). All but one occurred in smokers. These had a certain number of cigarettes smoked per day, years of smoking, and higher estimated overall number of smoked cigarettes when postoperative infections were present. The relative risk of smoking on infections was 12. A cutoff value of approximately 33,000 overall cigarettes smoked determined 3.3 percent false-positive and 0 percent false-negative rates.

CONCLUSIONS

Smoking is an important issue in aesthetic surgery that needs to be accurately addressed during the preoperative interview. In the future, the analysis of smoke-related, easy-to-gather variables such as the estimated overall number of cigarettes smoked until surgery could help stratify patients according to their risk of manifesting infections.

Wound infections in body contouring mastopexy with breast reduction after laparoscopic adjustable gastric bandings: the role of smoking

BACKGROUND

We retrospectively reviewed charts of 42 postbariatric patients who underwent mastopexy and breast reduction for body contouring to determine whether a significant relationship existed between cigarette smoking and postoperative wound infections and to determine the relative risk given by cigarettes and a cut-off value to predict infections.

METHODS

We excluded patients with ongoing clinical infections, recent bariatric surgery (within 1 year), recent antibiotic courses, or systemic diseases such as arteriosclerosis and diabetes mellitus.

RESULTS

All patients underwent bariatric surgery with the laparoscopic adjustable gastric bending technique and mastopexy with breast reduction for body contouring. Postoperative infections were present in 35.7% (n = 15) of patients, and 60% of these (n = 9) were superficial. Furthermore, 66.7% of them occurred in smoker patients, and 41.7% of smokers vs. 27.8% of nonsmokers developed infections. Significant differences between infected vs. infection-free patients were present for the number of pack years (p < 0.001) and the overall estimated cigarettes smoked (p < 0.001). A cut-off value of approximately 6.85 pack years (50,000 overall estimated cigarettes) distinguished between infections vs. infections-free patients, with 25% of false positives and 8% of false negatives. Relative risk conferred by smoking was 3.8.

CONCLUSIONS

The incidence of infections in our series of postbariatric patients undergoing mastopexy and breast reduction is 35.7%. A cut-off of 6.85 pack years (50,000 estimated overall cigarettes) was determined and, according to this value, the relative risk conferred by smoking was 3.8.

Infections after plastic procedures: incidences, etiologies, risk factors, and antibiotic prophylaxis

BACKGROUND

Through a review of the English literature, this study aimed to assess the incidence, etiology, risk factors, and preventive measures for postoperative infections occurring after plastic surgery operations.

METHODS

All studies describing the occurrence of infections after plastic surgery procedures including case reports, prospective trials, and retrospective series were selected.

RESULTS

The 85 articles analyzed showed that incidences differ greatly among procedures and seem to be influenced by different and specific risk factors for each operation. Etiologic agents are primarily bacteria, although mycobacteria, virus, and fungi also have been described. No agreement exists on the use of antibiotic prophylaxis, except for abdominoplasties, because few specific prospective trials are present in the literature.

CONCLUSIONS

Infections remain an important problem in plastic surgery with different points that still need to be clarified. Hopefully, in the future prospective randomized trials will definitively address this issue in order to provide plastic surgeons with clear and unbiased guidelines on its prevention and management.

Wound infections in post-bariatric patients undergoing body contouring abdominoplasty: the role of smoking

BACKGROUND

In this prospective study, we followed patients after laparoscopic adjustable gastric banding for morbid obesity who underwent abdominoplasty for body contouring. Our purposes were: 1) to determine if a significant relationship between cigarette smoking and postoperative wound infections existed, 2) the relative risk conferred by cigarettes and 3) a cut-off value for the increased risk.

METHODS

Patients scheduled for body contouring abdominoplasty were considered eligible. We excluded those with ongoing clinical infections, recent antibiotic administration, those within 1 year from their bariatric surgery and those with systemic diseases. Smokers were asked to stop smoking at least 4 weeks before surgery.

RESULTS

Since November 2004, we recruited 60 patients. Postoperative infections were present in 25% (n=15) of patients and 86.7% of these (n=13) were superficial. All except one occurred in smokers (P = 0.0001): 47% of smokers and 3% of nonsmokers developed infections. Significant differences between infections vs infection-free patients were present for the number of cigarettes smoked per day (P<0.001), years of smoking (P< 0.001), overall estimated cigarettes smoked and the number of pack years (P = 0.001). A cut-off value of approximately 62,000 overall estimated cigarettes (8.5 pack years) distinguished between infections vs infection-free patients (6.2% false positives and 7.1% false negatives). Relative risk conferred by smoking was 14 (95% confidence intervals 13.3-16.7).

CONCLUSIONS

The incidence of infections in post-bariatric patients undergoing body contouring abdominoplasties is 25%. The relative risk conferred by smoking was 14 and the cut-off value was 62,000 overall cigarettes (8.5 pack years).

Postoperative wound infections after breast reductions: the role of smoking and the amount of tissue removed

BACKGROUND

This prospective study followed patients who underwent breast reductions to determine the influence of smoking and the amount of tissue removed on postoperative wound infections.

METHODS

Patients who had received breast reductions were considered eligible for the study. The study excluded postbariatric patients and those with ongoing clinical infections, a recent antibiotic course, or systemic diseases that could impair tissue oxygenation. Smokers were instructed to quit smoking at least 4 weeks before surgery.

RESULTS

By March 2004, the study had enrolled 87 patients. Postoperative infections were present in 24 cases (27.9%). Infections included 16 in smokers (37.2%), 8 in nonsmokers (18.2%; p < 0.05), 14 in patients with large resections (>0.85 kg; 70%), and 10 in patients with small resections (14.9%; p < 0.001). Significant differences were found between the patients who experienced infections and those who were infection free in terms of the overall estimated cigarettes smoked (mean, 146,000; range, 29,200-228,125 vs mean, 10,950; range, 9,125-54,750; p < 0.001), the number of pack years (mean, 20; range, 4-31 vs mean, 2; range, 1-8; p < 0.001), and the amount of tissue removed (mean, 0.9 kg; range, 0.5-2 kg vs mean, 0.5 kg; range, 0.2-1.4 kg; p < 0.001). The analysis for all the patients determined an odds ratio of 2.04 for smoking and 4.7 for the amount of tissue removed.

CONCLUSIONS

Smoking and the amount of tissue removed are important issues in aesthetic breast surgery that need to be addressed accurately by the plastic surgeon. If future larger studies confirm these data, surgeons could have a simple and easy method for stratifying patients according to their risk for the development of wound infections and for prescribing specific preventive measures.

Bariatric and body-contouring surgery: a continuum of care for excess and lax skin

Obesity continues to reach epidemic proportions in the United States, with more than 60% of Americans classified as obese. Correspondingly, the number of individuals undergoing bariatric surgery has increased dramatically. There are several bariatric procedures that may be performed, with laparoscopic adjusted gastric band (LABG) the newest. Following bariatric surgery and massive weight loss, patients may be left with problematic loose, hanging skin. The loose or redundant skin may occur on the abdomen, back, upper arms, and inner and outer thighs. Body-contouring surgery may be performed to correct the residual excess tissues. Prebariatric planning for plastic surgery to correct skin defects, as well as postoperative bariatric and body-contouring care, is discussed.
