Abstract Spinal cord stimulation (SCS) is one of the most minimally invasive and effective treatments for intractable pain. We report the efficacy of a very small diameter neuroendoscope on setting the electrode to the proper site in the epidural space. Our cases include thalamic hemorrhage, and each patient had unilateral intractable pain on L1 or less as the main complaint. They had been treated for over two years in other hospitals, but no significant relief was achieved. Because each patient had been given frequent epidural blocks, the adhesion in the epidural space was expected. In Group A (3 cases), we used very small diameter neuroendoscope to dissect adhesion in the epidural space and to make optimal space for lead placement under direct vision. Conventional lead placement under fluoroscopy was performed in Group B (3 cases). Medtronic's PISCES lead system was used for SCS. In Group A, stimulation and pain regions matched in all cases, and good pain relief was also achieved. In Group B, however, stimulation and pain regions matched incompletely and the increase in stimulation caused stimulation on the pain-free side.
