To describe a novel technique by integrating the intraoperative neurophysiological monitoring (IONM) into laparoscopy to protect pelvic nerves by continuously monitoring when they are at risk during surgery.

We integrated intraoperative neuromonitoring system into laparoscopic lumbosacral plexus nerve decompression surgery and simultaneusly recorded nerve roots from lumbar 5 to sacral 4 during the operation. Diseases that cause pelvic nerve compression such as abnormal vascular conflict, aberrant priformis muscle, and endometriosis have settled in hard-to-reach deep areas of the pelvis. Sacral and sciatic nerves might be damaged when performing decompression surgery in these deep pelvic areas. We described a novel technique by integrating the intraoperative neurophysiological monitoring (IONM) into laparoscopy to protect pelvic nerves by continuously monitoring when they are at risk during surgery.

Inclusion Criteria:

• Patients with symptoms of chronic pelvic pain , dyspareunia, dysmenorrhea and severe, burning sharp pain on the lower extremity dermatomes, which had been present for at least one year were included.

Exclusion Criteria:

• Patients who underwent laparoscopic decompression surgery but did not give informed consent were not included in the study.
