BACKGROUND: Schwannoma is a rare benign tumor of peripheral nerves arising from Schwann cells of the ubiquitous nerve sheath. OBJECTIVE: To describe the operative steps and technical aspects of robotic laparoscopic resection of pelvic schwannoma. METHODS: We describe 2 patients with pelvic schwannoma: a 34-year-old woman with schwannoma of the right lumbosacral trunk and a 58-year-old woman with schwannoma of a left S1 nerve. Pain was the main symptom in both patients. The diagnosis was confirmed by magnetic resonance imaging and nerve biopsies. Both patients were operated on by robotic laparoscopy. RESULTS: Lesions were totally enucleated after incising the epineurium. After dissection of the schwannoma, the vascular pedicle and nerve fascicles involved were identified, coagulated, and then sectioned. The remaining fascicles of the nerve were preserved. The postoperative course was uneventful in both patients. With follow-up of 9 and 13 months, both patients obtained complete pain relief with no neurological sequelae. CONCLUSION: Robotic laparoscopic resection of pelvic nerve tumors such as schwannomas is technically feasible.
