Obesity is a significant public health problem in the United States, and many studies have established obesity as a significant risk factor for endometrial cancer. Surgery is the standard of care in staging and treatment of endometrial cancer, and obesity may influence surgical outcomes because of its attendant comorbid conditions. Therefore, assessment of the impact of obesity on surgical outcome is important for decreasing morbidity and improving survival in patients with endometrial cancer. The aims of this research were to evaluate and review epidemiologic data systematically on the impact of obesity on surgical outcomes and to assess safety and feasibility of newer surgical techniques in obese patients. A systematic search of PubMed was conducted to identify articles between 2004 and 2013 that focused on the impact of obesity on surgical outcome. Reference lists of retrieved articles were also used to identify other relevant articles. Thirteen relevant articles were reviewed. Evidence from epidemiologic studies showed that obesity impacts surgical outcome adversely. On average, obese patients have worse surgical outcomes than their nonobese counterparts. In addition, surgical outcome worsens as level of obesity increases. However, surgical procedure also influences this association. Minimally invasive surgeries are more useful and are accompanied with fewer complications than conventional laparotomy and can be performed safely in obese patients. Obesity is a significant risk in the etiology, treatment, and surgical outcomes of patients with endometrial cancer. Future research will need more randomized controlled trials and prospective studies to identify the best procedures for maximal outcomes. (J GYNECOL SURG 32:149).
