Surgical Training and Standardised Management Guidelines Improved the 30-Day Complication Rate After Abdominoplasty for Massive Weight Loss

Developing the Aesthetic Postoperative Complication Score (APeCS) for Detecting Major Morbidity in Facial Aesthetic Surgery

BACKGROUND

Facial aesthetic surgery encompasses a variety of procedures with complication rates that are difficult to estimate due to a lack of published data.

OBJECTIVES

We sought to estimate major complication rates in patients undergoing facial aesthetic procedures and develop a risk assessment tool to stratify patients.

METHODS

We utilized the Tracking Operation and Outcomes for Plastic Surgeons (TOPS) database from 2003-2018. The analytic database included major facial aesthetic procedures. Univariate analysis and a backward stepwise multivariate regression model identified risk factors for major complications. Regression coefficients were utilized to create the score. Performance robustness was measured with area under receiver operating characteristic curves and sensitivity analyses.

RESULTS

A total of 38,569 patients were identified. The major complication rate was 1.2% (460). The regression model identified risk factors including over 3 concomitant surgeries, BMI ≥25, ASA class ≥2, current or former smoker status, and age ≥45 as the variables fit for risk prediction (n = 13,004; area under curve: 0.68, standard error: 0.013, [0.62-0.67]). Each of the 5 variables counted for 1 point, except over 3 concomitant surgeries counting for 2, giving a score range from 0 to 6. Sensitivity analysis showed the cutoff point of ≥3 to best balance sensitivity and specificity, 58% and 66%, respectively. At this cutoff, 65% of cases were correctly classified as having a major complication.

CONCLUSIONS

We developed an acceptable risk prediction score with a cutoff value of ≥3 associated with correctly classifying approximately 65% of those at risk for major morbidity when undergoing face and neck aesthetic surgery.

BMI and Revision Surgery for Abdominoplasties: Complication Definitions Revisited Using the Clavien-Dindo Classification

After body contouring surgery of the lower trunk (CSLT), the definition, rate (4%-70%), and documentation of complications vary.

Objectives

We analyzed the effect of risk factors on the outcome based on the Clavien-Dindo classification (CDC) after CSLT surgery and polled postoperative satisfaction among patients.

Methods

All patients undergoing CSLT from 2001 to 2016 were included and were classified according to the CDC for postoperative events. Statistical analysis included proportional odds logistic regression analysis. We polled patients to grade their satisfaction with the postoperative result and whether they would have the operation performed again.

Results

A total of 265 patients were included: 60 (22.6%), 25 (9.4%), 28 (10.6%), and 21 (7.9%) were in CDC grades I, II, IIIa, and IIIb, respectively. A high preoperative body mass index significantly increased the odds for a postoperative event requiring revision surgery under general anesthesia (CDC grade IIIb, odds ratio 0.93, 95% confidence interval 0.89-0.97, P = 0.001). One-hundred twenty-eight patients (48.3%) participated in the poll: 101 (78.9%) were either happy or content with the postoperative results, and 117 (91.4%) would have the procedure performed again, including all nine patients with CDC grade IIIb.

Conclusions

Our results confirm that a high body mass index is a statistically significant risk factor for requiring major revision surgery after CSLT. Despite being a complication prone intervention, postoperative satisfaction after CSLT was ranked favorably in our sample. We recommend that the CDC be used in all surgical specialties to evaluate complications and permit future comparability of pooled data.

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.

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.

Outcome of Body-Contouring Procedures After Massive Weight Loss

BACKGROUND

With the increased popularity of bariatric surgery, the demand for body-contouring procedures is growing. Associated with these procedures are a number of complications due to different risk factors and patients' characteristics. The aim of this study was to assess the outcome of body-contouring procedures and correlate it to possible risk factors.

METHODS

The study included a collective of 112 patients who underwent 157 body-contouring procedures. Patients' characteristics, risk factors, and complications have been recorded. Three groups were formed based on the type of surgical procedure to perform correlations of BMI, weight of resected tissue, and length of hospital stay using Spearman's rank test. Correlations between patients' risk factors and complication occurrence were analyzed with Fisher's exact test.

RESULTS

The most common procedure patients underwent was the classic abdominoplasty (n = 53). A significant correlation was found between preoperative BMI and weight of resected tissue in abdominoplasties (rho = 0.69), Fleur-de-Lis abdominoplasties (rho = 0.64), and body lifts (rho = 0.60). There was a significant correlation between weight of resected tissue and length of hospital stay (rho = 0.53) and preoperative BMI and length of hospital stay (rho = 0.4) as well. There was no significant correlation between patients' comorbidities or smoking status and the postoperative complication rate. The mean weight of resected tissue was higher in patients with than without complications requiring surgical revision.

CONCLUSIONS

The relevance of risk factors commonly believed to have an influence on postoperative complications should be revised. The weight of resected tissue has an influence on complication.
