Background: Obesity may increase the risk of complications following abdominal contouring. The aim of this study is to evaluate panniculectomy outcomes in patients with class III obesity (BMI > 40 kg/m2). Methods: The American College of Surgeon’s National Surgical Quality Improvement Program ACS-NSQIP (2010–2014) was used to identify patients who underwent panniculectomy. Class III obesity patients were identified. Demographics, comorbidities and postoperative outcomes were evaluated. Risk-adjusted multivariate logistic regression analyses were performed to assess impact of class III obesity on panniculectomy outcomes. Results: A total of 4497 panniculectomies were identified. Of these, 545 (12.1%) were performed in patients with class III obesity. This group was older (mean age 50.3 vs. 45.9, p < 0.01) with a higher proportion of men (23.4 vs. 12.4%, p < 0.01). Class III obesity group also had higher rates of comorbidities (p < 0.01). Postoperatively, class III obesity patients experienced much higher rates of wound complications (17.8 vs. 6.8%), sepsis (3.3 vs. 0.8%), venous thromboembolism (1.5 vs. 0.7%) and medical complications (6.4 vs. 1.8%), p < 0.05. Additionally, this group had higher rates of unplanned reoperation (9.2 vs. 3.7%) and 30-day readmissions (3.5 vs. 1.0%), p < 0.01. On risk-adjusted multivariate regression analyses, class III obesity was independently associated with increased risk of wound complications (OR 2.22, p < 0.01), sepsis (OR 3.53, p < 0.01), medical adverse events (OR 1.98, p < 0.05), unplanned reoperation (OR 1.62, p < 0.05) and 30-day readmission (OR 2.30, p < 0.05). Conclusion: Class III obesity patients are at significantly increased risk of adverse outcomes following abdominal contouring. Plastic surgeons should consider these risks for counseling and preoperative risk optimization. Level of Evidence IV: This journal requires that authors assign a level of evidence to each article.
