From July 2009, we started spinal micro-endoscopic surgery to reduce the degree of surgical invasion. The reduced invasiveness of spinal endoscopy is considered especially valuable in surgery for lumbar canal stenosis (LCS). We evaluated spinal micro-endoscopic surgery for LCS in comparison with laminectomy performed in 2008.We treated 18 patients (14 men and 4 women) with LCS using spinal micro-endoscopy in comparison with 44 patients (21 men and 23 women) who underwent LCS with laminectomy operations. In either group, the mean age was 71 years. The mean operation time per level was 163 min in the endoscopy group and 49 min in the laminectomy group. The mean amount of intraoperative blood loss per level was 38 g in the endoscopy group and 77 g in the laminectomy group. The mean period from surgery to the start of walking was 1.2 day in the endoscopy group and 1.9 day in the laminectomy group. Spinal endoscopic surgery for LCS is less invasive, but requires a much longer operation time. We perform spinal endoscopic surgery only for patients with ASA physical status 1 or 2.
