Abstract:
Objective To explore the significance of combining applications of multi-mode electrophysiological monitoring in microsurgical resection of spinal tumors of lumbar and sacral segments.Methods A retrospective analysis of 31 patients with spinal tumors of lumbar and sacral segments accepted microsurgical resection in our hospital from December 2016 to June 2017 was performed.All tumors were located in the T12 spinal canal or lower.Multi-mode electrophysiological monitoring techniques were applied during operation:motor evoked potential (MEP) and somatosensory evoked potential (SEP) of double lower limbs,bulbocavernosus sphincter reflex (BCR),electromyogram (EMG).Spinal functions of the patients were assessed by Japanese orthopaedic association (JOA) before and after surgery.Results Total resection was achieved in 28 patients,subtotal resection in 3.There were 29 patients reaching electrophysiological warning criteria during the operation,including 27 with transient changes and 2 with permanent changes.The improvement rate of JOA score included 4 cases of cure,20 cases of obvious effect,5 cases of effectiveness and 2 cases of inefficiency after follow up 6 months to 1 year.Conclusion It is of significance of multi-mode electrophysiological monitoring techniques being used in microsurgical resection of spinal tumors of lumbar and sacral segments to protect the motor and sensory functions,bowel and bladder functions and sexual function.
