Introduction/Background Obturator nerve originates from L2–L3 and enters the pelvic cavity after piercing the medial border of the psoas muscle. It is located along the retroperitoneum within the obturator fossa. Finally it leaves the pelvis through the obturator foramen and innervates the medial thigh adductor muscles.

Although rare, obturator nerve injury complicating major pelvic oncologic surgery can occur.

Methodology Retrospective review of a series of four cases of obturator nerve injury during oncological surgery.

Results The Oncology Gynecology Department performed 1.226 pelvic lymphadenectomies between January 2000 and December 2018. The incidence of obturator nerve injury in oncological surgery in our Department is 0.32% (4/1.226).

Four cases’ most relevant data are summarized in the attached table.

Conclusion Inmediate laparoscopic repair of a transacted obturator nerve during gynaecologic surgery is feasible and could prevent or reduce the severity of the postoperative neurological injury.

Disclosure Nothing to disclose.
