Percutaneous endoscopic discectomy and dural repair for L3-L4 intradural lumbar disc herniation presenting with cauda equina syndrome: A case report with a literature review.
Article in Orthopedic reviews, 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
Introduction: Intradural lumbar disc herniation (ILDH) is a rare condition causing severe neurological deficits and diagnostic challenges due to overlap with other intradural lesions. Case presentation: A 68-year-old male presented with seven-month low back pain, leg numbness, and saddle anesthesia due to L3-L4 ILDH complicated by cauda equina syndrome. Management and outcomes: Single-port percutaneous endoscopic discectomy was performed with complete discectomy and dural repair using an artificial patch and biological glue. Postoperatively, the patient showed significant pain relief, improved left leg strength (grade 4.5/5), restored bladder and bowel function, and MRI confirmed adequate decompression. At 1-month follow-up, he regained full independence with only mild residual left leg numbness. Conclusion: Single-port endoscopic discectomy effectively treats ILDH with cauda equina syndrome, facilitating significant neurological recovery and supporting minimally invasive approaches.
