Background: Postoperative complications in body contouring surgery have been linked to several factors, including body mass index, diabetes, cardiovascular disease, and skin resection weight. Prior weight loss by surgical means is another predisposing factor for postoperative complications following body contouring. This study aims to examine these previously identified variables, and several others, in the context of a spectrum of abdominal body contouring techniques following bariatric surgery. Our goal is to highlight that current evidence supports the notion that the prior history of bariatric surgery does not significantly impact body contouring surgery's success and its associated complications.
Methods: A retrospective cohort study including all consecutive patients (N = 198) who underwent abdominal body contouring between January 2011 and January 2022 following bariatric surgery was performed. Data collected included patient demographics, medical history, perioperative variables, and postoperative outcomes. Univariate and multivariate statistical analysis was performed.
Results: Sixty-four (32%) patients developed a postoperative complication. In the univariate analysis, patients who developed a postoperative complication were more likely to have a mental health disorder (63% vs 44%, P = 0.015) and to have undergone abdominal surgery other than panniculectomy (P = 0.002). They also had significantly longer median operative time (160 minutes, σ = 68.9, vs 140 minutes, σ = 72.3, P = 0.037) and longer follow-up time (99 days, σ = 471.1 vs 23 days, σ = 430.5, P < 0.001). In a multivariate logistic regression model including diabetes, hypertension, abdominoplasty type, operative time, skin excision weight, and concurrent body contouring procedure, the only significant factor in complication rate was the type of abdominal body contouring. Specifically, the traditional (odds ratio: 2.72, 95% confidence interval: 1.25-5.93) and vertical abdominoplasty (odds ratio: 5.50, 95% confidence interval: 1.17 to 25.87) techniques were more likely to lead to complications compared with panniculectomy abdominoplasty, respectively.
Conclusions: Previously cited risk factors such as diabetes, body mass index, and skin resection weight did not increase the chance of complications. Panniculectomy appears to be a safer option for those with a history of bariatric surgery.
