OBJECTIVE: In order to highlight the importance of intraoperative complications and their management, we demonstrate a video of an iatrogenic left obturator nerve lesion during a pelvic lymphadenectomy for endometrial cancer staging. The repair was promptly performed using an intracorporeal laparoscopic suture for an end-to-end tension-free nerve anastomosis.
DESIGN: Stepwise demonstration of the technique with narrated video footage.
SETTING: A 70-year-old woman with a stage IB grade I endometrial adenocarcinoma was submitted to a surgical laparoscopic staging with total hysterectomy(TH), bilateral adnexectomy(BA), and bilateral pelvic and lomboaortic lymphadenectomy. After an uneventful retroperitoneal lomboaortic lymphadenectomy, the left paravesical space was dissected until the obturator fossae and a left pelvic lymphadenectomy followed, during which the left obturator nerve was accidentally transected with LigaSure™.
INTERVENTIONS: A careful inspection revealed an almost complete transection (80%) of the nerve, with both proximal and distal cut ends identifiable and no fraying of the edges. The thickness of the non-sectioned nervous portion was less than 3 mm, but a tension-free reattachment of both edges seemed manageable. The edges were oriented towards each other and a single stitch suture was placed using a 5-0 prolene, providing an epineural end-to-end coaptation. To reinforce the suture, a Fibrin sealant Tissucol® was applied. The contralateral pelvic lymphadenectomy was then performed, followed by TH and BA. The pieces were removed through the vagina using an endobag. The patient was discharged on the second postoperative day. During the follow-up, there were no signs of diminished adductor function, and neither there was any other detectable residual neuropathy or neurologic deficit involving the left thigh.
CONCLUSION: It is crucial to identify intraoperative complications and to develop abilities to manage them. This video proves that it is possible to repair a transected obturator nerve using laparoscopy, when performed by an experienced onco-gynecologist, with extremely good functional results.
