Outcomes
Primary outcomes are intra- and post-operative complications before and after 30 days, blood transfusions, readmissions < 30 days, return to theatre rates and 5-year disease-free and disease-specific survival. Intra-operative complications are defined as any type of surgical complication occurring during the operation. Post-operative complications within 30 days are graded according to the Clavien-Dindo classification.20
Secondary outcomes are estimated blood loss, operating time, rate of conversions, CCU-admissions, length of stay longer than 1 day and lymphoedema. A conversion was defined as the need to convert to laparotomy after docking of the robot due to an intra-operative complication or impossibility to continue robotically due to adhesions.
Prognostic risk groups according to European Society of Gynaecological Oncology (ESGO) were assessed.21 These recently developed guidelines for risk group determination incorporate clinicopathologic and molecular parameters and effectively predict survival in endometrial cancer.22
