A Simplified and Efficient Transforaminal Endoscopic Lumbar Discectomy Technique With Reduced Radiation: A Retrospective Study.
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
backgroundMost transforaminal endoscopic lumbar discectomy (TELD) surgeries performed under local anesthesia involve intricate procedures, require multiple fluoroscopy sessions, and have a steep learning curve. This study introduces a modified technique aimed at optimizing TELD for lumbar disc herniation.
methodsA total of 76 patients (42 men and 34 women, mean age 53.8 years) underwent TELD using a "Guiding Rod" for simplified positioning and visual trephine for foraminoplasty. Parameters, including the fluoroscopy frequency, positioning time, foraminoplasty time, operation time, and intraoperative blood loss, were meticulously recorded and retrospectively analyzed. The Visual Analog Scale pain score, Japanese Orthopedic Association, and Oswestry Disability Index score were evaluated preoperatively and at 3 days, 3 months, and 6 months postoperatively.
resultsImplementing our modified technique resulted in a mean fluoroscopy frequency of 3.93 ± 0.97 times and a mean positioning time of 3.60 ± 1.10 minutes. The mean foraminoplasty time was 3.88 ± 1.82 minutes, and the mean operation time was 48.38 ± 10.85 minutes. Intraoperative blood loss remained consistently below 15 mL, with no reported complications. All clinical scores (visual analog scale, Japanese Orthopedic Association, and Oswestry Disability Index) improved significantly compared with preoperative values.
conclusionsThe use of the "Guiding Rod" for simplified positioning alongside visual trephine application in TELD for lumbar disc herniation demonstrates ease of operation and safety and minimizes radiation exposure, thereby optimizing TELD technology. CLINICAL RELEVANCE: This study highlights advanced techniques in transforaminal endoscopic discectomy. LEVEL OF EVIDENCE: 4:
