Utility of the scope retractor for adhesiolysis in unilateral biportal endoscopic lumbar surgery: illustrative cases.

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
backgroundDuring unilateral biportal endoscopic (UBE) lumbar surgery, adhesiolysis can be technically challenging compared with microscopic lumbar surgery because of the constraints imposed by single-handed manipulation. The authors evaluated the use of a scope retractor as an adjunctive tool to facilitate bimanual-like tissue handling. OBSERVATIONS: Two illustrative cases with severe epidural adhesions-one related to postoperative scarring and the other associated with chronic inflammation from a synovial cyst-were treated with the aid of a scope retractor, which was used either to secure adhesive tissue or as a dissecting instrument. Successful adhesiolysis and adequate neural decompression were achieved in both cases. LESSONS: UBE surgery provides high-quality visualization that enhances differentiation between the dura mater and surrounding soft tissue. Incorporation of a scope retractor facilitates precise tissue handling by providing an effect analogous to bimanual manipulation, improving surgical outcomes in cases with severe epidural adhesions. https://thejns.org/doi/10.3171/CASE26223.
