| 【Abstract】 Objective：To compare the clinical outcomes of minimally invasive surgery（MIS） and open surgery for single-level lumbar stenosis and to evaluate the safety and reliability of MIS for single-level lumbar stenosis.Method：From Jan 2008 to Jan 2009，15 patients with single level lumbar stenosis underwent single-level MIS decompression and transforaminal lumbar interbody fusion（TLIF），while 45 cases with the same problems underwent traditional open decompression and posterior lumbar interbody fusion（PLIF）.The operative time，X-ray exposure time，pereoperative blood loss，postoperative ambulation，and bed time were compared between two groups.Futhermore，clinical outcomes in terms of Oswestry Disability Index（ODI），back and leg pain Visual Analogue scores（VAS），and X-ray examination were performed before surgery，after surgery and during follow-up.Result：There was no difference with respect to preoperative demographic data，VAS and ODI scores between two groups.MIS group had longer operative time and X-ray exposure time than open group（P<0.01），but less pereoperative blood loss than open group（P<0.01）.MIS group had shorter postoperative bed time than open group（P<0.01）.The VAS score of back pain at 5th day postoperative in MIS group was higher than open group（P<0.05）.There was no difference between two groups with respect to VAS and ODI scores at other timepoints.No difference for lumbar fusion rate was noted between two groups.Conclusion：MIS and open groups can achieve similar safety and reliability，but as for the pereoperative blood loss，postoperative bed time，MIS group is superior than open group. |
