Influence of obesity on surgical complications of patients with ovarian tumors

Influence of obesity on surgical complications and survival of patients with ovarian tumors were investigated. In total, 362 patients who were diagnosed with ovarian cancer by biopsy in the Department of Pathology of Shanxi Dayi Hospital Affiliated to Shanxi Medical University from April 2012 to July 2017 were selected as research subjects for retrospective analysis. The patients were divided into the obesity group [body mass index (BMI) ≥28] (n=64), the overweight group (≥24 BMI <28) (n=124), the normal body weight group (≥18.5 BMI <24) (n=108) and the low body weight group (BMI <18.5) (n=66). The surgical conditions and postoperative complications of patients in the 4 groups were compared, and the patients were followed up for prognosis for one year, and their mortality rates were recorded. The surgical time, intraoperative blood loss amount and blood transfusion amount of the patients in the obesity group were the highest, followed by the overweight group (P<0.05). Among the 4 groups, the prognosis of patients in the obesity group was also the worst. The incidence rates of complications among all groups were compared, and the incidence rate of complications in the obesity group was the highest (50.00%), followed by the overweight group (30.65%), the low body weight group (13.64%) and the normal body weight group (4.63%), (P<0.05). The prognosis follow-up results showed that the 1-year mortality rate in the obesity group was the highest (35.94%), followed by the overweight group (28.23%). For patients with ovarian cancer, obesity raises the risks of postoperative complications and worsens their prognosis. Therefore, indexes of patients with tumors associated with high BMI should be monitored more strictly after surgeries.
