RESUMO
The aim of this study was to compare the financial and clinical outcomes in robotic-assisted laparoscopic surgery for primary endometrial cancer between obese and nonobese women. The hospital finance department assessed the total admission costs for robotic surgery for endometrial cancer in 54 women. This included a subanalysis for costs over nine areas (ward and clinics, drugs and pharmacy, medical staff, theaters, blood products, imaging, pathology, rehabilitation therapy, and high dependency costs). Furthermore, a prospective collection of morbidity and surgical outcome data was performed. The study group included 21 nonobese and 33 obese women (body mass index >30). Obese women were more likely to stay for more than one night in hospital (20/33 [60.6%] compared to 4/21 [19.0%], P=0.032) and to have high dependency care (25/33 [75.8%] compared to 10/21 [47.6%], P=0.032). Theater time was on average 35 min longer (95% confidence interval [CI] 5-65 min, P=0.0252). Both the groups were comparable for comorbidities except for the presence of diabetes being present in the obese group (13/33 [39.4%] compared to 0/21 [0.0%], P=0.007). There were six Clavien-Dindo grade II complications in the obese group and two in the nonobese group. The average overall costs were £1,852 greater (95% CI £431-£3,277, P=0.012) in the obese group. Diabetes and hypertension were associated with increased costs, but obesity was the only independent variable. In conclusion, greater resource should be allocated to obese women undergoing primary surgery for endometrial cancer.
