Obesity is a predictor of morbidity in 1,629 patients who underwent adrenalectomy.


Journal Article

BACKGROUND: We examined the impact of obesity on 30-day outcomes of adrenalectomy using a multi-institutional database. METHODS: Patients who underwent adrenalectomy in 2005-2008 according to the American College of Surgeons-National Surgical Quality Improvement Project (ACS-NSQIP) data set were grouped by body mass index (BMI): normal weight (BMI=18.5-24.9 kg/m2), overweight (BMI=25.0-29.9 kg/m2), obese (BMI=30.0-34.9 kg/m2), and morbidly obese (BMI≥35 kg/m2). Outcomes of the higher BMI groups were compared to those of the normal BMI group using χ2, analysis of variance (ANOVA), and multivariate regression. RESULTS: There were 1,629 patients in the study: 22% were normal weight, 31% overweight, 22.2% obese, and 24.7% morbidly obese. Compared to normal-weight patients, obese and morbidly obese patients had a 12.5 and 16.7% increase in operation times (129 vs. 145 and 150 min, respectively, p≤0.01) and sustained more wound complications (0.2 vs. 0.4 and 1.2%, p<0.001), including superficial and deep wound infections (p<0.001 and p<0.01, respectively). Morbid obesity independently predicted overall complications (odds ratio [OR] 2.9, 95% confidence interval [CI]: 1.7-5.7), wound complications (OR 6.1, 95% CI: 2.0-18.9), and septic complications (OR 3.1, 95% CI: 1.1-8.8). Obesity independently predicted longer total time in the operating room (p<0.006). There were no differences in rates of reoperation and length of hospital stay by BMI category. CONCLUSION: Obesity is an independent risk factor that needs to be considered in surgical decisions regarding adrenalectomy. Morbidly obese adrenalectomy patients are particularly at risk for wound and septic complications.
