Neurolyse du nerf cutané latéral de la cuisse par voie mini-invasive robot-assistée – faisabilité technique à propos d’un cas

Abstract

To limit the risk of iatrogenic neuroma and of recurrence after surgical treatment of meralgia paresthetica, some authors have recently developed a technique of endoscopic neurolysis of the lateral cutaneous nerve of thigh (LCNT) below the level of the inguinal ligament. We report the case of a robot-assisted endoscopic technique underneath the inguinal ligament. A 62-year-old patient suffering of idiopathic meralgia paresthetica for the past 18 months received a Da Vinci robot-assisted minimally-invasive 10 cm long neurolysis, of which 1 3 was situated above the level of the inguinal ligament and 2 3 below it. The patient was discharged the following day without complications. At 6 months follow-up, the pain was rated 0 10 compared to 5 10 preoperatively. Robot-assisted endoscopic neurolysis of the LCNT retains the advantages of conventional endoscopy and enables to approach the nerve in the most frequently compressed zone underneath the inguinal ligament. The three-dimensional view offered by robotic surgery facilitates the dissection. The superiority of this technique remains to be demonstrated by comparing it to conventional techniques.
