Purpose:
The objective of this systematic review and metaanalysis is to compare the efficacy and safety of decompression alone versus decompression plus fusion in single-level lumbar spinal stenosis with spondylolisthesis.
Methods:
A comprehensive search of the PubMed, Embase, Cochrane Library, and Ovid Medline databases was conducted to find randomized control trials (RCTs) or cohort studies that compared decompression alone and decompression plus fusion in single-level lumbar spinal stenosis with spondylolisthesis. Operation time; reoperation; postoperative complications; postoperative Oswestry disability index(ODI) scores and scores related to back and leg pain were collected from eligible studies for meta-analysis.
Results:
We included 3 randomized controlled trials and 9 cohort studies with 6182 patients. The decompression alone group showed less operative time(P < 0.001) and intraoperative blood loss(p = 0.000), and no significant difference in postoperative complications was observed in randomized controlled trials(p = 0.428) or cohort studies(p = 0.731). There was no significant difference between the other two groups in reoperation(P = 0.071), postoperative ODI scores and scores related to back and leg pain.
Conclusions:
In this study, we found that the decompression alone group performed better in terms of operation time and intraoperative blood loss, and there was no significant difference between the two surgical methods in rate of reoperation and postoperative complications, ODI, low back pain and leg pain. Therefore, we come to the conclusion that decompression alone is not inferior to decompression and fusion in patients with single-level lumbar spinal stenosis with spondylolisthesis.
