Gas-Containing Disc Herniation at L1/2 Successfully Treated by Full-Endoscopic Transforaminal Discectomy: A Case Report.

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
Gas-containing lumbar disc herniation is a rare condition, with limited reports detailing its management. This case report presents the successful treatment of a gas-containing lumbar disc herniation using full-endoscopic discectomy via the transforaminal approach (FED-TFA) at an upper lumbar level, a challenging clinical scenario for which the application of this technique has been scarcely reported. An 81-year-old male patient with a complex surgical history involving multiple lumbar decompressions and spinal instrumentation presented with persistent numbness in the left lateral calf and progressively worsening pain in the left thigh. Magnetic Resonance Imaging and Computed Tomography scans confirmed a gas-containing disc herniation at L1/2. Conservative treatment was unsuccessful, and symptoms worsened significantly, prompting surgical intervention via FED-TFA. The patient's leg pain resolved immediately postoperatively; the visual analog scale score for leg pain improved from 6/10 preoperatively to 0/10 on postoperative day 1. This symptom relief was sustained, with no recurrence of leg symptoms at the one-year follow-up. This case highlights the potential of FED-TFA as an effective surgical option for treating refractory gas-containing lumbar disc herniation. Its key advantages include the ability to circumvent scarred posterior tissue while preserving posterior elements (such as the facet joint) and avoiding paraspinal muscle dissection, offering a critical "fusion-sparing" benefit. Furthermore, direct endoscopic visualization enables the thorough and controlled evacuation of intradiscal gas. These combined advantages make FED-TFA particularly suitable for complex cases at challenging spinal levels.
