Lumbar Spinal Endoscopy: Mature, Durable, and Established-Not Investigational.
Article in International journal of spine surgery, 2026. 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
backgroundLumbar spinal endoscopy has long been mischaracterized by payers as investigational. Such claims conflict with decades of refinement, randomized trials, and policy precedent.
methodsWe reviewed the historical evolution, prospective trials, meta-analyses, and policy milestones of transforaminal endoscopic lumbar discectomy (TELD), with emphasis on coding, reimbursement, and comparative effectiveness.
resultsEvidence demonstrates that TELD, performed with direct visualization, provides durable outcomes with complication, reoperation, and conversion rates equal or superior to open decompression. Meta-analyses confirm comparable effect sizes to microsurgery, while selective integration with motion-preserving adjuncts extends durability in complex cases.
conclusionTELD has matured into a safe and durable technology. It is not limited to lateral recess disease but is capable of effectively addressing central stenosis, including select cases with low-grade spondylolisthesis. TELD's trajectory mirrors that of other coverage-adopted technologies, and its future impact depends on structured training to ensure reproducibility and broad patient access. CLINICAL RELEVANCE: This work establishes that transforaminal endoscopy, performed with direct visualization, is not limited to lateral recess disease. TELD can safely and effectively address central stenosis, including selected cases with low-grade spondylolisthesis. Contemporary evidence demonstrates durable outcomes comparable to open decompression. The next step is structured training to ensure reproducibility across the broader surgical community, thereby securing patient access to this established and codified technique within recognized coverage frameworks.
