This study was designed to evaluate the feasibility and lymphatic complications of robotic pelvic and infrarenal paraaortic lymphadenectomy in endometrial cancer patients. Material and methods All patients diagnosed with high risk endometrial cancer during the study period were identified ( n = 212). Clinical prospective data, with reassessment of lymphatic complications, was analysed for all cases ( n = 140) planned for a complete robotic nodal staging. The outcome measures were: success rate of infrarenal paraaortic lymphadenectomy, the rate of lymphatic complications and factors associated with nodal yield. Results Of the 212 women, an open or restricted robotic procedure was performed in 57 women (27%) and no operation in 15 (7%), the latter due to disseminated disease or comorbidity. In 140 women (66%) in whom staging was intended, the lymphadenectomy included the infrarenal area in 70%, was restricted to the inframesenteric area in 21% and aborted or incomplete in 9%. The median number of paraaortic nodes was 10 (range 2–39). An unsuccessful staging was associated with high BMI and the surgeon's inexperience. At 1 year, three patients (2%) had developed a grade two lower limb lymphedema. Eleven women (8%) demonstrated pelvic lymphocysts; seven (64%) resolved spontaneously. Only one paraaortic lymphocyst was found; this required drainage. No cases of chylous ascites occurred. Conclusions An infrarenal robotic paraaortic lymphadenectomy is feasible in 70% of high risk endometrial cancer cases when intended (88% in non‐obese patients operated by experienced surgeons), but is restricted in obese patients and by surgeon's inexperience.
