Comparative Analysis Of Microendoscopic And Open Laminectomy For Single-Level Lumbar Spinal Stenosis At L1-L2 Or L2-L3 London Spine Lumbar Stenosis

The article compared the surgical outcomes and radiographic evaluations of microendoscopic laminectomy (MEL) and open laminectomy for single-level decompression cases at L1-L2 or L2-L3 for lumbar spinal stenosis (LSS). The study analyzed patients from 12 distinguished spine centers and compared baseline demographics, preoperative, and 1-year postoperative patient-reported outcomes (PROs), as well as imaging parameters. The MEL group exhibited significantly improved postoperative EQ-5D scores compared to the open group, but had a lower facet preservation rate. However, the lower facet preservation rate in the MEL group did not lead to a higher postoperative instability rate. Overall, the MEL group showed potential advantages in enhancing EQ-5D scores compared to open laminectomy

Although overall surgical outcomes were similar, the MEL group demonstrated potential advantages in enhancing EQ-5D scores. The MEL group’s lower facet preservation rate did not translate into a higher postoperative instability rate.

Abstract

Background: Several reports have highlighted comparable surgical outcomes between microendoscopic laminectomy (MEL) and open laminectomy (open) for lumbar spinal stenosis (LSS). However, the unilateral approach in MEL may present challenges for the upper lumbar levels, where facet joints are located deeper inside. Our objective was to compare surgical outcomes and radiographic evaluations for single-level decompression cases at L1-L2 or L2-L3 between MEL and open laminectomy.

Methods: We analyzed patients who underwent single-level decompression for upper LSS at 12 distinguished spine centers from April 2017 to September 2021. Baseline demographics, preoperative, and 1-year postoperative patient-reported outcomes (PROs), along with imaging parameters, were compared between the MEL and open groups. To account for potential confounding, patients’ backgrounds were adjusted using the inverse probability weighting method based on propensity scores.

Results: Among the 2487 patients undergoing decompression surgery, 118 patients (4.7%) underwent single-level decompression at L1-L2 or L2-L3. Finally, 80 patients (51 in the MEL group, 29 in the open group) with postoperative data were deemed eligible for analysis. The MEL group exhibited significantly improved postoperative EQ-5D values compared to the open group. Additionally, the MEL group showed a lower facet preservation rate according to computed tomography examination, whereas the open group had a higher incidence of retrolisthesis.

Although overall surgical outcomes were similar, the MEL group demonstrated potential advantages in enhancing EQ-5D scores. The MEL group’s lower facet preservation rate did not translate into a higher postoperative instability rate.
