Abstract

Objective: To evaluate the effect of obesity on clinical and financial outcomes of minimally invasive hysterectomy Methods: This was a retrospective cohort study of 5 affiliated hospitals. We obtained demographic, operative, and financial characteristics to analyze the effects of obesity on outcomes, including operating room (OR) time, estimated blood loss (EBL), length of stay (LOS), adverse perioperative events, and hospital charges. Obesity was stratified by the following classes: no obesity (BMI <30 kg/m2), class I (BMI 30–34 kg/m2), class II (BMI 35–39 kg/m2), and class III (BMI >40 kg/m2). Descriptive statistics and multivariate logistic and linear regressions were performed. Results: A total of 2483 women underwent benign, minimally invasive hysterectomy. Laparoscopic was the most common approach (79.8%), followed by robotic (12.2%), and vaginal (8.0%). Mean BMI was 30.13 ± 6.99 kg/m2, and total charges were US $13 928 ± $5954. Each additional minute in the OR increased costs by US $47.89 (P < 0.001). Compared with patients without obesity, OR time and EBL were significantly higher among patients with class I or II obesity and highest among patients with class III obesity (P < 0.001). Obesity did not affect LOS or occurrence of adverse perioperative events. Although obesity appeared to be a significant predictor of hysterectomy charges, after adjusting for covariates, charges for laparoscopic and robotic hysterectomy did not differ significantly by BMI. Conclusion: Obesity appears to have a significant effect on clinical outcomes of benign hysterectomy that is approach-dependent and most notable among patients with class III obesity. BMI was not, however, a predictor of financial outcomes.
