OBJECTIVE: To describe the technical feasibility and early outcomes of robot-assisted laparoscopic neurolysis (RALN) of the lumbosacral plexus in patients with chronic neuralgias secondary to post-traumatic or iatrogenic fibrosis.
SETTINGS: The study was conducted in a tertiary referral center specializing in advanced robotic surgery and neuropelveology for chronic pelvic pain syndromes.
PARTICIPANTS: Series of 11 procedures performed between 2024 and 2025. All patients had failed earlier multidisciplinary medical management. Lumbo-sacral fibrosis was secondary to post-traumatic (5 cases) or iatrogenic hematomas (4 cases). The diagnosis of nerve compression was confirmed by clinical examination, pelvic MRI, and a targeted lidocaine block showing >50% pain relief with dermatomal anesthesia as described in pudendal neuralgia protocols [1].
INTERVENTIONS: We illustrate our series with the case of a 41-year-old woman who developed a chronic hematoma following a left sacrospinous ligament fixation for prolapse repair. Progressive fibrosis resulted in refractory sciatic, posterior femoral cutaneous, and pudendal neuralgias, with associated motor, sensory, and vegetative disturbances. A RALN of the lumbosacral plexus was performed using a standardized four-step technique, adapted from our previously described pudendal approach and other published methods [2-5]. Intraoperative video documentation was used to detail the procedure. Postoperative care followed an enhanced recovery protocol. Early results at 4 months of follow-up reported improvement in pain, ambulation, and seating tolerance. Two Clavien-Dindo 1 complications were reported. A 1-year follow-up is planned to assess sustained recovery and nerve regeneration.
CONCLUSION: RALN of the lumbosacral plexus appears to be a feasible approach for selected cases of chronic pelvic pain caused by post-traumatic or iatrogenic fibrotic entrapment. This advanced technique should be reserved for specialized centers with expertise in neuropelveology and carries a potential risk of neurovascular complications. VIDEO ABSTRACT.
