Laparoscopic Resection of a Pelvic Schwannoma with Intraoperative Electromyography Monitoring

Symptomatic neural tumors arising in the pelvis generally require large incisions and intraoperative electromyographic (EMG) monitoring for safe removal by laparotomy. Here we report laparoscopic removal of a 6cm schwannoma arising from the right S2 nerve root in a 40-year-old woman. The patient reported back and leg pain for five years with recent radiation to perineum. Magnetic resonance imagining revealed a 6 x 3.3 cm, homogeneous, low-density mass arising from the presacrum. Laparoscopic removal of this tumor was performed with intra-operative EMG monitoring using a nerve stimulator insulated with a latex catheter and passed through a 5mm port. Patient was discharged home the next day with no sensory or motor deficits. Laparoscopy with EMG monitoring is a safe approach that enhances surgical recovery.
