Surgical complications comparing extraperitoneal vs transperitoneal laparoscopic aortic staging in early stage ovarian and endometrial cancer.

Objective: To determine whether the extraperitoneal approach for paraaortic staging lymphadenectomy results in a lower rate of surgical complications compared to the transperitoneal approach, without compromising oncological outcomes.

Methods: Prospective randomized multicenter study of patients with early endometrial or ovarian cancer undergoing paraaortic lymphadenectomy in 2010-2019. Patients were randomized to minimally invasive surgery (laparoscopy or robotic-assisted) using an extraperitoneal or a transperitoneal approach.
