Early Clinical and Radiologic Evaluation of Endoscopic Unilateral Laminectomy for Bilateral Decompression in Degenerative Lumbar Spinal Stenosis: A Retrospective Study.
Article in International journal of spine surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundEndoscopic unilateral laminectomy for bilateral decompression (ULBD) is gaining attention as a minimally invasive procedure for treating spinal stenosis. However, comprehensive studies on its outcomes remain limited. PURPOSE: This study aims to evaluate the changes in radiologic parameters and clinical outcomes associated with endoscopic ULBD for treating spinal stenosis.
methodsA retrospective study was conducted on 53 patients with central lumbar spinal stenosis who underwent endoscopic ULBD decompression surgery. Pre- and postoperative visual analog scale and Oswestry Disability Index scores were collected to assess the impact on activities of daily living. Parameters such as operation time, intraoperative blood loss, postoperative drainage volumes (first and second day), total hospital stay, and postoperative hospital stay were recorded. Additionally, pre- and postoperative imaging changes were documented, and MacNab functional scores were evaluated at 6 months postoperatively to assess clinical efficacy.
resultsNo nerve injuries occurred during the operation. Two cases of cerebrospinal fluid leakage were successfully treated with pressure dressings, and no postoperative complications such as incision infection or dehiscence were observed. At 6-month follow-up, postoperative visual analog scale scores and Oswestry Disability Index showed significant improvement compared with preoperative levels (
conclusionsThis study demonstrates that endoscopic ULBD can provide favorable outcomes for single-segment central lumbar spinal stenosis under local anesthesia at a relatively low cost.
