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
