Use of the vessel sealer in paraaortic lymphadenectomy in the robotic assisted approach in endometrial cancer.

Minimally invasive surgery is the method of choice in endometrial cancer. Experience in procedures assisted by a robotic system is growing rapidly. One of the new bipolar ones is a Vessel Sealer, with sealing and cutting function. The aim of the study was to compare robotic surgery assisted with the da Vinci X system with use of the Vessel Sealer or without it. The study included 25 patients with high-risk endometrial cancer after completed pelvic and paraaortic lymphadenectomy with mean age 60.07 ± 10.67 (range 34.69-83.23) years divided into two groups: one with use of the Vessel Sealer; the second one only with monopolar scissors and subdivided by one-site versus dual docking. Duration of the operation was significantly associated with previous surgery (p < 0.005). Use of the Vessel Sealer was associated with lower blood loss during surgery (p < 0.05). The number of removal pelvic lymph nodes was higher in case of Vessel Sealer with no relation to BMI. Experience in robotic surgery allowed for shortened operation time and led to better outcomes. The Vessel Sealer used in robotic surgery appears to reduce blood loss during surgery and operation time, especially in the case of previous surgery, however, it increases costs of the procedure.
