Abdominal Panniculectomy: Determining the Impact of Diabetes on Complications and Risk Factors for Adverse Events

Obesity as a Risk Factor in Cosmetic Abdominal Body Contouring: A Systematic Review and Meta-Analysis

BACKGROUND

The incidence of obesity is on the rise around the globe. Outside of the massive weight loss (MWL) patient population, knowledge of risk factors associated with abdominal body contouring (BC) is limited. This systematic review and meta-analysis assesses the impact of obesity has on cosmetic abdominal BC outcomes.

METHODS

A systematic review conducted in accordance with PRISMA 2020 was done. PubMed, Embase, Scopus, and COCHRANE databases were reviewed under search syntax "obesity," "abdominoplasty," "panniculectomy," and "body contouring" for articles. Cosmetic was defined as abdominoplasty or panniculectomy outside the context of MWL. Obesity was defined as BMI ≥ 30 kg/m2. Studies reporting postoperative outcomes with less than 50% of their population involving MWL patients were included. Postoperative outcomes were assessed by pooled analysis and meta-analysis.

RESULTS

Of 3088 initial studies, 16 met inclusion criteria, and nine were used for pooled and meta-analysis. Meta-analysis demonstrated that obesity was associated with more seromas (OR 1.45, 1.06-1.98, p = 0.02), hematomas (OR 2.21, 1.07-4.57, p = 0.03), and total surgical site occurrences (OR 1.99, 1.30-3.04, p = 0.0016). There was no significant difference in odds of any other complications. Analysis by obesity class showed no significant increase in odds in seromas or wound dehiscence.

CONCLUSIONS

This review demonstrates obesity increased odds of postoperative complications following cosmetic abdominal BC. However, risk of complications does not continue to increase with higher obesity class. A BMI ≥ 30 kg/m2 should not be a strict contraindication to cosmetic abdominal BC. Instead, plastic surgeons should evaluate patients on a case-by-case basis.

Abdominal Panniculectomy: Determining the Impact of Diabetes on Adverse Outcomes and Complications

Background: Despite its association with obesity, the relation between diabetes and the abdominal panniculectomy is less well-established. The purpose of this study was to evaluate the result of diabetes on post-panniculectomy complications in a large cohort and to establish the risk factors associated with unfavorable post-operative outcomes. Methods: Patients that underwent a panniculectomy between 2010 and 2018 were identified in PearlDiver, a national insurance claims database, and identified by Current Procedural Terminology code 15380. Patient demographics and comorbidities were elucidated, and various complications were then identified. Descriptive statistics as well as a multivariate analysis were used to evaluate the association of risk factors and complications. Results: A total of 8282 panniculectomy patients were identified-4245 with diabetes, 4037 without. Obesity, tobacco use, and diabetes were all identified as significant risk factors in developing a surgical site infection, wound disruption, as well as needing to undergo reoperation. Diabetic panniculectomy patients had a higher rate of readmission as well as reoperation and sustained a higher rate of surgical complications, even when matched for. Conclusion: Diabetic panniculectomy patients are at a greater risk for developing complications. Identifying potential risk factors in this patient population could help reduce post-operative complications following a panniculectomy.

Perioperative Risk Stratification Model for Readmission after Panniculectomy

BACKGROUND

Readmission is an important metric for surgical quality of care. This study aimed to develop a validated risk model that reliably predicts readmission after panniculectomy using the American College of Surgeons National Surgical Quality Improvement Program database.

METHODS

The American College of Surgeons National Surgical Quality Improvement Program database was queried to identify all patients who had undergone panniculectomy from 2005 to 2018. The outcome of interest was 30-day readmission. The cohort was divided randomly into 70 percent development and 30 percent validation groups. Independent predictors of 30-day readmission were identified using multivariable logistic regression on the development group. The predictors were weighted according to beta coefficients to generate an integer-based clinical risk score predictive of readmission, which was validated against the validation group.

RESULTS

For the model selection, 22 variables were identified based on criteria of p < 0.05 percent and complete data availability. Variables included in the development model included inpatient surgery, hypertension, obesity, functional dependence, chronic obstructive pulmonary disease, wound class greater than or equal to 3, American Society of Anesthesiologists class greater than 3, and liposuction. Receiver operating characteristic curve analysis of the validation group rendered an area under the curve of 0.710, which demonstrates the accuracy of this prediction model. The predicted incidence within each risk stratum was statistically similar to the observed incidence in the validation group ( p < 0.01), further highlighting the accuracy of the model.

CONCLUSIONS

The authors present a validated risk stratification model for readmission following panniculectomy. Prospective studies are needed to determine whether the implementation of the authors' clinical risk score optimizes safety and reduces readmission rates.

The Impact of Diabetes on Outcomes and Health Care Costs Following Anterior Cervical Discectomy and Fusion

STUDY DESIGN

Retrospective cohort study.

OBJECTIVES

Anterior cervical discectomy and fusion (ACDF) is commonly used to treat an array of cervical spine pathology and is associated with good outcomes and low complication rates. Diabetes mellitus (DM) is a common comorbidity for patients undergoing ACDF, but the literature is equivocal about the impact it has on outcomes. Because DM is a highly prevalent comorbidity, it is crucial to determine if it is an associated risk factor for outcomes after ACDF procedures.

METHODS

Patients at a single institution from 2008 to 2016 undergoing ACDF were compared on the basis of having a prior diagnosis of DM versus no DM. The 2 cohorts were compared utilizing univariate tests and multivariate logistic and linear regressions.

RESULTS

Data for 2470 patients was analyzed. Diabetic patients had significantly higher Elixhauser scores (P < .0001). Univariate testing showed diabetic patients were more likely to suffer from sepsis (0.82% vs 0.10%, P = .03) and bleeding complications (3.0% vs 1.5%, P = .04). In multivariate analyses, diabetic patients had higher rates of non-home discharge (odds ratio [OR] = 1.37, 95% confidence interval [CI] = 1.07-1.75, P = .013) and prolonged length of stay (OR = 1.95, 95% CI = 1.25-3.05, P = .003), but similar complication (OR = 1.46, 95% CI = 0.85-2.52, P = .17), reoperation (OR = 0.77, 95% CI = 0.33-1.81, P = .55), and 90-day readmission (OR = 1.53, 95% CI = 0.97-2.43) rates compared to nondiabetic patients. Direct cost was also shown to be similar between the cohorts after adjusting for patient, surgical, and hospital-related factors (estimate = -$30.25, 95% CI = -$515.69 to $455.18, P = .90).

CONCLUSIONS

Diabetic patients undergoing ACDF had similar complication, reoperation, and readmission rates, as well as similar cost of care compared to nondiabetic patients.

"Abdominal panniculectomy: Identifying complications and potential risk factors"

BACKGROUND

The abdominal panniculectomy is a common procedure that patients choose to undergo for the purpose of restoring hygiene, reducing infection, and improving personal esthetic. A panniculectomy is often indicated after bariatric surgery, which defines a high-risk patient population. This study sought to better establish the association of known risk factors that can complicate the postoperative care of the panniculectomy patient, and whether or not bariatric surgery plays a role in the development of these complications.

METHODS

Patients that underwent a panniculectomy between 2010 and 2018 were identified in PearlDiver, a national insurance-claims database, and identified by CPT code 15,380. Patient demographics and associated medical problems were elucidated, and various complications were then identified. Descriptive statistics as well as a multivariate analysis were used to evaluate the association of risk factors and complications.

RESULTS

A total of 8,282 panniculectomy patients were identified. Of these, 1,420 underwent bariatric weight loss surgery prior to their panniculectomy, whereas the remaining 6,869 underwent a panniculectomy alone. Obesity, tobacco use, and diabetes were significant in developing a surgical site infection, wound disruption, and the need to undergo reoperation. Charlson Comorbidity Index greater than one (CCI>1), male gender, age greater than 60, COPD, and HTN identified as potential risk factors in developing various complications. Although patients with prior weight loss surgery had a history significant for prior comorbidities, the overall postoperative complication rate was decreased compared to those who did not undergo preoperative bariatric surgery.

CONCLUSION

In the face of the obesity epidemic, the incidence of undergoing a panniculectomy has increased significantly, particularly following bariatric surgery. Identifying potential risk factors in this patient population could better help identify postoperative complications following a panniculectomy and perhaps allow for targeted intervention and medical optimization prior to surgery.

Functional panniculectomy vs cosmetic abdominoplasty: Multicenter analysis of risk factors and complications

BACKGROUND

Amidst the rising trend of bariatric surgical procedures being performed across the country and around the world, patients seeking functional panniculectomy after massive weight loss represent a different population than those seeking cosmetic abdominoplasty. The purpose of this study was to determine whether certain complications are more likely to occur in patients undergoing functional panniculectomy, as well as identify risk factors that are implicated in the occurrence of adverse events.

METHODS

Retrospective cohort study was conducted of patients undergoing cosmetic abdominoplasty and functional panniculectomy in North America between 2015 and 2019 using the National Surgical Quality Improvement Program database sponsored by the American College of Surgeons. Comorbidities and postoperative complications between these two cohorts were analyzed with appropriate statistics.

RESULTS

During the study interval, 11,137 patients underwent excision of excessive infraumbilical abdominal skin, including 57.4% (n = 6397) patients undergoing functional panniculectomy and 42.6% (n = 4740) patients undergoing cosmetic abdominoplasty. Patients undergoing functional panniculectomy were significantly more likely to have comorbidities than those undergoing cosmetic abdominoplasty (p < .001). Overall adverse events (p < .001), medical complications (p = .047), surgical complications (p < .001), related readmission (p < .001), and related reoperation (p < .001) were significantly higher in patients undergoing functional panniculectomy. Surgical complications significantly higher in functional panniculectomy included superficial incisional infection (p < .001), deep incisional infection (p < .001), organ/space infection (p < .001), dehiscence (p = .003), and bleeding requiring transfusion (p = .003).

CONCLUSIONS

Patients undergoing functional panniculectomy are significantly more likely to have comorbidities and experience postoperative wound infection, dehiscence, sepsis, bleeding, related readmission, and related reoperation.

Applications of Ultrasound in the Postoperative Period: A Review

Background Recent advances in ultrasound technology have further increased its potential for routine use by plastic and reconstructive surgeons.

Methods An extensive literature review was performed to determine the most common applications of ultrasound in the postoperative care of plastic and reconstructive surgery patients.

Results In contrast with other available imaging modalities, ultrasound is cost-effective, rapid to obtain, eliminates the need for ionizing radiation or intravenous contrast, and has virtually no contraindications. In addition to its diagnostic capabilities, ultrasound can also be used to facilitate treatment of common postoperative concerns conveniently at the bedside or in an office setting.

Conclusion This article presents a review of the current applications of ultrasound imaging in the postoperative care of plastic and reconstructive surgery patients, including free flap monitoring following microsurgery, diagnosis and treatment of hematoma and seroma, including those associated with BIA-ALCL, and breast implant surveillance.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Abdominal Panniculectomy: An Analysis of Outcomes in 238 Consecutive Patients over 10 Years

Panniculectomy is a commonly performed body contouring procedure to address skin laxity and its related complications. This study aimed to assess clinical outcomes of abdominal panniculectomy and identify predictors of complications at a tertiary academic healthcare center.

Methods

A retrospective review of patients who underwent panniculectomy between January 2010 and January 2020 at our institution was performed. Exclusion criteria were a history of prior panniculectomy or abdominoplasty. Patient characteristics and clinical outcomes were collected. Univariate and multivariable analyses were performed to assess the risk factors of complications.

Results

The mean age in the included 238 patients was 51.7 ± 12.7 years, and the mean body mass index (BMI) at the time of panniculectomy was 33 ± 7.5 kg/m². Median resection weight was 2.7 kg (range: 0.15-14.6) and median length of hospital stay was 2 days (range: 0-24). Mean follow-up time was 50 ± 37 months. The rate of major complications was 22.3%. Revision surgery was performed in 3.4% of the cases. Multivariable analyses demonstrated that increase in BMI (P = 0.007) and active smoking (P = 0.026) were significantly associated with increased odds of major complication, and increase in BMI (P = 0.0004), history of venous thromboembolism (P = 0.034) and having a concomitant ventral hernia repair (P = 0.0044) were significantly associated with having a length of hospital stay of 3 days or more.

Conclusions

Panniculectomy is generally safe to perform, with major postoperative complication rate of 22.3% in our series. Increase in BMI and active smoking were significantly associated with having a major complication. Higher BMI, concomitant hernia repair, and a history of venous thromboembolism were associated with length of hospital stay of 3 days or more.

Abdominal Body Contouring: Does Body Mass Index Affect Clinical and Patient Reported Outcomes?

BACKGROUND

Obese individuals are thought to be higher risk for complications after excisional abdominal body contouring (EAC) due to co-morbidities and significant tissue resection.

OBJECTIVES

We comparatively analyzed EAC patients with Body Mass Index (BMI) ≥35 kg/m² and BMI <35 kg/m² to highlight key differences in clinical and patient-reported-outcomes (PROs).

METHODS

Patients ≥18 years-old undergoing EAC by a single surgeon from 01/2018-01/2020 were identified and separated into cohorts based on BMI (<35 and ≥35 kg/m²). Patients were excluded if they had a cosmetic abdominoplasty without history of bariatric surgery or massive weight loss, or if they had <1000 gs of tissue resected. Clinical outcomes and PROs using the BODY-Q were comparatively analyzed.

RESULTS

70 total patients with median BMIs of 30[26-32] and 41[37-45] kg/m² in each cohort, were identified. Patients with BMI ≥35 kg/m² were more likely to have higher ASA (P<0.01) and use of incisional negative pressure wound devices (P = 0.042). Alternatively, they were less likely to have had concurrent liposuction (P = 0.05). There were no differences in development of an SSO, SSI or SSOpi (P>0.05) between cohorts. Multivariate logistic regression showed that BMI ≥35 kg/m², iNPWD and liposuction were not associated with the development of complications. PROs demonstrated improvement in multiple domains despite BMI.

CONCLUSION

There was no association with BMI ≥35 kg/m² and the development of complications within our cohort. We encourage preoperative weight loss when possible, however these procedures can be performed safely with acceptable outcomes even in individuals who are obese and/or require extensive tissue removal.

Updates in Diabetic Wound Healing, Inflammation, and Scarring

Diabetic patients can sustain wounds either as a sequelae of their disease process or postoperatively. Wound healing is a complex process that proceeds through phases of inflammation, proliferation, and remodeling. Diabetes results in several pathological changes that impair almost all of these healing processes. Diabetic wounds are often characterized by excessive inflammation and reduced angiogenesis. Due to these changes, diabetic patients are at a higher risk for postoperative wound healing complications. There is significant evidence in the literature that diabetic patients are at a higher risk for increased wound infections, wound dehiscence, and pathological scarring. Factors such as nutritional status and glycemic control also significantly influence diabetic wound outcomes. There are a variety of treatments available for addressing diabetic wounds.

Panniculectomy Outcomes by Body Mass Index: an Analysis of 12,732 Cases

Purpose

With an increasing rate of obesity in the USA, bariatric surgery has become widespread, resulting in a greater number of patients seeking panniculectomy. The authors aim to determine the complication profile of panniculectomies by body mass index (BMI).

Methods

The 2012–2018 National Surgical Quality Improvement Program database was queried for all panniculectomy cases. Patients were assigned to a category by their calculated BMI. Rates of complications were compared across BMI ranges. Demographics, comorbidities, and perioperative factors were compared between those with and without complications. Multivariable analyses were performed to analyze the associations between BMI ranges and post-surgical complications.

Results

Twelve thousand seven hundred thirty-two cases were analyzed, of which 1759 (13.8%) had at least one postoperative complication. As BMI increased, patients were more likely to experience postoperative complications (p<0.001). Patients experiencing complications were more likely to be male, older, of a higher BMI group, have a higher American Society of Anesthesiologists Personal Status classification, be an inpatient, have various comorbidities, or be undergoing a concurrent procedure. On multivariable analysis, patients who were overweight (OR=1.24, p=0.039), with class 1 (OR=1.72, p<0.001), class 2 (OR=2.10, p<0.001), or class 3 (OR=3.01, p<0.001) obesity were more likely to have a postoperative complication. Wound complications were particularly prevalent in patients who were overweight (OR=1.77, p=0.001) or with class 1 (OR=2.59, p<0.001), class 2 (OR=4.05, p<0.001), or class 3 (p=5.84, p<0.001) obesity compared to non-overweight patients.

Conclusion

A higher BMI is associated with more postoperative complications, particularly wound healing complications, following panniculectomy in a dose-dependent manner.

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

Background

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

Objectives

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

Methods

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

Results

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

Conclusions

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

Outcomes of patients older than 55 years undergoing abdominoplasty after bariatric surgery

BACKGROUND

Bariatric surgery has become widely performed for treating patients with morbid obesity, and the age limits are being pushed further and further as the procedure proves safe. After massive weight loss, many of those patients seek body-contouring surgery for excess skin and fat.

OBJECTIVES

To analyze the feasibility and the safety of abdominoplasty in patients older than 55 years old after bariatric surgery.

SETTING

University hospital medical center.

METHODS

We performed a retrospective review of prospectively collected data from patients aged older than 55 years who had undergone abdominoplasty following massive weight loss due to a bariatric surgery at a single institution from 2004 to 2017. The data analyzed included age, gender, preoperative body mass index, associated interventions, co-morbidities, and postoperative complications.

RESULTS

We retrieved records for 104 patients; 85.6% percent of them were female, and the mean age was 60.1 ± 3.9 years old. Of the 104 patients, 21 (20.2%) underwent a sleeve gastrectomy and 77 (74%) underwent a Roux-en-Y gastric bypass. The mean interval between the bariatric surgery and the abdominoplasty was 33.6 ± 26.9 months. The mean preoperative weight and body mass index were 76.1 ± 14.5 kg and 28.9 ± 4.5 kg/m², respectively. A total complication rate of 20% was observed. The only factor significantly associated with postoperative morbidity was the associated procedure (P = .03), when we performed another procedure at the same time as the abdominoplasty. Complications included postoperative bleeding in 5 patients (4.8%), seromas in 5 patients (4.8%), surgical site infections in 12 patients (11.5%), and wound dehiscence or ischemia in 2 patients (1.9%). No mortality occurred.

CONCLUSION

Abdominoplasty can be safely performed in carefully selected patients older than 55 years old after weight loss surgery, and does not present increased morbidity or mortality. We recommend that surgeons avoid adding concomitant procedures when possible, to decrease the risk of complications. It is also important to look at the patient's previous maximum BMI levels, as a higher maximum BMI can predict higher postoperative risks and longer hospital stays.

Panniculectomy at the time of bariatric surgery: a propensity score-matched analysis of outcomes in the MBSAQIP database

BACKGROUND

Body contouring in the postbariatric surgery patient improves quality of life and daily function.

OBJECTIVES

To determine the risk profile of panniculectomy when performed in select patients at the time of bariatric surgery.

SETTING

Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) participating centers.

METHODS

We examined the MBSAQIP database (2016-2017), in which data on 379,544 bariatric surgeries are reported. Concurrent panniculectomy procedures were identified by Current Procedural Technology (CPT) codes. Patient characteristics and in-hospital as well as 30-day complications were compared between the body contouring group and propensity score-matched bariatric surgery controls.

RESULTS

One hundred twenty-four patients met inclusion criteria and were matched to 248 controls. An infra-umbilical panniculectomy was performed in the majority of patients (n = 94, 75.8%). Most patients received an open rather than laparoscopic bariatric surgery (n = 87, 70.2%). There were no statistically significant differences between 30-day mortality (1.9%), wound complications (11.5%), readmission (12.5%) and reoperation (5.8%) between the 2 groups (P > .05). Wound complications occurred in 11.5% of patients and were associated with prolonged hospital stay (odds ratio 4.65, 95% confidence interval 1.99-10.86, P < .001) and a body mass index (BMI) > 50 (odds ratio 3.19, 95% confidence interval 1.02-9.96, P = .046).

CONCLUSION

In select patients, panniculectomy at the time of bariatric surgery was not associated with increased in-hospital or 30-day adverse outcomes compared with matched bariatric surgery controls. This procedure may be performed in select patients, with awareness that revision surgery may be needed once weight loss stabilizes.

Low Complication Rates Using Closed-Incision Negative-Pressure Therapy for Panniculectomies: A Single-Surgeon, Retrospective, Uncontrolled Case Series

BACKGROUND

Panniculectomies are associated with high complication rates (43 to 70 percent), particularly in patients with obesity, smoking, and diabetes mellitus. Closed-incision negative-pressure therapy can be used postoperatively to support healing by promoting angiogenesis and decreasing tension. The authors hypothesized that using it with panniculectomies would minimize complications, and that a longer duration of therapy would not increase the incidence of complications. The authors also evaluated whether closed-incision negative-pressure therapy malfunction was associated with complications.

METHODS

This retrospective, uncontrolled case series analyzed 91 patients who underwent panniculectomies managed with closed-incision negative-pressure therapy performed by a single surgeon from 2014 to 2018. Patients were followed for 6 months; therapy duration and malfunction were recorded. Patients were placed into therapy duration groups (2 to 7, 8 to 10, or >10 days). Complications managed conservatively were minor and major if they required intervention. Odds ratios were performed with 95 percent confidence intervals and p values.

RESULTS

Mean follow-up was 225.1 days and mean closed-incision negative-pressure therapy duration was 10.5 days. Major complications were reported in five patients (5.5 percent), infections in four (4.4 percent), dehiscence in two (2.2 percent), and seroma in four (4.4 percent). Patients with malfunction [n = 16 (17.6 percent)] were more likely to experience complications (OR, 3.3; p = 0.043). No significant increase in complications was found with therapy duration longer than 10 days, but potentially there is an increased risk of infection (OR, 4.0; p = 0.067).

CONCLUSIONS

Although high complication rates have been associated with panniculectomies, the authors' results show that low complication rates can be achieved with closed-incision negative-pressure therapy. Randomized controlled trials need to be conducted evaluating different therapy systems and the optimal duration of therapy with panniculectomies.

Efficacy of panniculectomy-combined surgery in superobese patients with endometrial cancer: A case report and literature review

•

Incidence of endometrial cancer has shown a remarkable increase globally.

•

Case of an obese patient who underwent panniculectomy combined surgical staging.

•

Combination of panniculectomy was effective for surgery in obese patients.

Introduction

Panniculectomy is regarded as an effective approach in highly obese patients with endometrial cancer to improve surgical access or space of the surgical field.

Presentation of case

A 66-year-old nulliparous woman was brought in from another hospital to our institute for newly diagnosed endometrial carcinoma. The patient was 158 cm in height and weighed 135.8 kg during the first visit to our hospital. Her body mass Index (BMI) was 54.4 kg/m². Unfortunately, the patient developed an umbilical hernia and strangulation before the surgery. Emergency partial ileal resection and simple closure of the umbilical hernia were performed. We were finally able to perform simple hysterectomy, and bilateral salpingo-oophorectomy with panniculectomy. Her weight at the time of surgery was 115.5 kg which had been reduced by 20 kg from the time she was first brought in, and the BMI decreased from 54.4 to 45.3 kg/m². The patient underwent follow-up without adjuvant therapy since she was in the low-risk group, and showed no signs of recurrence 12 months after surgery.

Discussion

There are various risks associated with surgery in highly obese patients. Diabetes mellitus, hypertension and smoking are reported to be risk factors of wound complication in panniculectomy, and it was reported that diabetes mellitus was an independent risk factor.

Conclusion

The combination of panniculectomy was considered as an effective approach to perform safe surgery for obese patients.

Advanced Age Is a Risk Factor for Complications Following Abdominal Panniculectomy

BACKGROUND

Widespread adoption of bariatric surgery in the treatment of obesity has led to greater numbers of patients seeking panniculectomy, including aged patients, who represent a rapidly growing proportion of the U.S population. Although the quality of life and functional benefits of abdominal panniculectomy have been established, its safety in patients 65 years and older has not been evaluated.

METHODS

The American College of Surgeons National Surgical Quality Improvements (ACS-NSQIP) database was used to identify patients undergoing panniculectomy between 2010 and 2015. Age 65 years and older was the risk factor of interest, and primary outcomes included 30-day wound complications, overall complications, reoperation, readmission, and mortality. Multivariate regression was performed to control for confounders.

RESULTS

Review of the database identified 7030 patients who underwent abdominal panniculectomy. When stratified by age, 6455 (91.8%) of patients were younger than 65, and 575 (8.2%) were 65 or older. Multivariate regression analysis demonstrated that age over 65 was a significant independent risk factor for wound complications (OR = 1.81; 95% CI 1.35-2.42; p < 0.001) and all complications (OR = 1.46; 95% CI 1.15-1.87; p = 0.002). BMI, smoking, diabetes, and partial or total dependence were also identified as significant independent risk factors for wound and all complications.

CONCLUSION

Our analysis demonstrates that advanced age is an independent risk factor for wound and overall complications following abdominal panniculectomy. These results highlight the importance of preoperative evaluation and optimization of modifiable preoperative risk factors as well as close postoperative follow-up for safe outcomes in patients 65 and older.

Panniculectomy at the time of living donor renal transplantation: An 8-year experience

Panniculectomy can be performed as a prophylactic procedure preceding transplantation to enable obese patients to meet criteria for renal transplantation. No literature exists on combined renal transplant and panniculectomy surgery (LRT-PAN). We describe our 8-year experience performing LRT-PAN. A retrospective chart review of all patients who had undergone LRT-PAN from 2010 to 2018 was conducted. Data were collected on patient demographics, allograft survival and function, and postoperative course. Fifty-eight patients underwent LRT-PAN. All grafts survived, with acceptable function at 1 year. Median length of stay was 4 days with a mean operative duration of 363 minutes. The wound complication rate was 24%. Ninety-day readmission rate was 52%, with medical causes as the most common reason for readmission (45%), followed by wound (32%) and graft-related complications (23%). Body mass index, diabetes status, and previous immunosuppression did not influence wound complication rate or readmission (P = .7720, P = .0818, and P = .4830, respectively). Combining living donor renal transplant and panniculectomy using a multidisciplinary team may improve access to transplantation, particularly for the obese and postobese population. This combined approach yielded shorter-than-expected hospital stays and similar wound complication rates, and thus should be considered for patients in whom transplantation might otherwise be withheld on the basis of obesity.

National Surgical Quality Improvement Program Analysis of 9110 Reduction Mammaplasty Patients: Identifying Risk Factors Associated With Complications in Patients Older Than 60 Years

BACKGROUND

The purpose of this study was to identify preoperative risk factors in patients undergoing reduction mammoplasty as well as identify any increased complication risk in patients older than 60 years undergoing reduction mammoplasty.

METHODS

The American College of Surgeons National Surgical Quality Improvement Program data from years 2013-2015 was reviewed. Patients were identified using Current Procedural Terminology code 19318 specific for reduction mammoplasty. Only patients undergoing bilateral procedures were included, and no reconstructive procedures were included. Patient demographics, comorbidities, and 30-day complications were analyzed. Comparative analysis was performed between patients younger than 60 years and patients 60 years and older, identifying risk factors associated with complications in the geriatric population.

RESULTS

A total of 9110 patients undergoing reduction mammoplasty were identified. Of these 1442 (15.83%) were patients older than 60 years. Mean age of all patients was 42 years (range, 18-85 years). Eighty hundred fifty-nine patients were active smokers. Four hundred eighty-two patients were diabetic. Overall, 798 complications occurred with an incidence of 8.7%. Group 1 (<60 years) mean age was 39 years (range, 18-59). Group 2 (>60 years) mean age was 66 years (range, 60-85 years). The geriatric population showed a higher risk of cerebral vascular accidents (P < 0.00006), myocardial infarction (P < 0.02), and readmission (P < 0.03). Smoking was found to be a statistically significant risk factor for superficial surgical site infection, and deep space infection. Diabetes was found to be a statistically significant risk factor for readmission.

CONCLUSIONS

Reduction mammoplasty is a common surgical procedure. It is not uncommon for patients older than 60 years to undergo elective reduction mammoplasty (15.83% incidence), resulting in a cumulative complication rate of 11.65% in the geriatric population compared with 8.89% in the group of patients younger than 60 years. Smoking and diabetes were found to be independent risk factors for complications, regardless of age.
