説明
<p>The optimal management of lumbar spinal canal stenosis with spondylolisthesremains controversial, particularly when choosing between decompression alone or decompression with fusion. Current evidence is based on conventional open or endoscopy-assisted surgeries, with limited data on full-endoscopic decompression. This study aimed to assess the impact of spondylolisthesis on outcomes after full-endoscopic laminotomy by evaluating back pain-related disability scores in patients with lumbar spinal canal stenosis, with and without spondylolisthesis. A retrospective analysis was conducted at Iwai Orthopaedic Hospital, Japan. Patients with lumbar spinal canal stenosis who underwent full-endoscopic laminotomy between January 2021 and December 2022 were included and categorized into those without spondylolisthesis and those with spondylolisthesis. Postoperative Oswestry Disability Index scores at 2 years were compared in the groups using multivariable linear regression, adjusting for confounding factors. Exploratory analyses were also conducted to identify factors affecting the Oswestry Disability Index in the patients with lumbar spinal canal stenosis with spondylolisthesis group. Statistical significance was set at p < 0.05. The study included 80 patients, with 40 in each group. Both groups showed improved postoperative Oswestry Disability Index. There was no significant association between spondylolisthesis and postoperative Oswestry Disability Index. However, cauda equina redundancy negatively affected postoperative Oswestry Disability Index improvement in the patients with lumbar spinal canal stenosis with spondylolisthesis group. Full-endoscopic laminotomy is an effective surgical option for lumbar spinal canal stenosis, leading to significant alleviation of disability and improvements in quality of life, regardless of spondylolisthesis. Full-endoscopic laminotomy may offer similar functional improvements regardless of the presence of low-grade spondylolisthesis, supporting its role as a less invasive alternative to fusion.</p>
