percutaneous endoscopic unilateral-approach bilateral decompression for lumbar spinal stenosis

Degenerative lumbar spinal stenosis (DLSS) can result from alterations in bony, discal, capsular, or ligamentary anatomical structures. Clinically, LSS presents with a range of symptoms, including radiating sciatic pain in the legs, neurogenic claudication during ambulation, and sensory disturbances, all of which significantly affect patients&#39; quality of life1,2,3. An initial conservative management period of two months is the recommended therapeutic approach for LSS. If conservative measures prove ineffective, transitioning to surgical decompression therapy becomes the subsequent recommendation.
Historically, open laminectomy has been the traditional surgical approach for addressing spinal stenosis. Peer-reviewed studies have confirmed its safety and cost-effectiveness, with outcomes showing notable superiority compared to non-surgical interventions4,5,6,7,8. However, the complexities involved in achieving comprehensive bony decompression of neural components can introduce the risk of segmental spinal instability. This may lead to symptom recurrence or a subsequent need for arthrodesis9,10. Distinctively, Ghogawala et al.11 documented that approximately 34% of patients, after undergoing traditional laminectomy for lumbar spinal stenosis with concomitant stable spinal spondylolisthesis, required revision surgery within four years post-operatively.
Over the past five decades, a discernible shift toward minimally invasive spinal surgical procedures has become evident. The overarching objective has been to reduce approach-related tissue disruption and subsequently mitigate post-operative discomfort and disability. This transition aligns seamlessly with the advent and progression of percutaneous endoscopic spine surgery.
Synchronized with advancements in endoscopic technology and a deepened understanding of endoscopic anatomical intricacies, contemporary endoscopic spine surgeons are now equipped to address a spectrum of LSS presentations safely and effectively. Specifically, lumbar endoscopic unilateral laminotomy for bilateral decompression (LE-ULBD) has gained traction as a favored modality for LSS management12,13,14,15,16,17(Figure 1). Paramount benefits of LE-ULBD include minimal incision requirements, avoidance of soft tissue disruption and muscular denervation, along with improved visualization.
Between May 2017 and May 2021, our institution employed the LE-ULBD technique to manage 132 patients with LSS. Relevant technical details and outcomes over a two-year follow-up period are elucidated herein. Based on these findings, LE-ULBD emerges as a minimally invasive, effective, and secure modality, positioning it as a viable alternative therapeutic strategy for patients diagnosed with lumbar central canal stenosis and/or lateral recess stenosis.

Perkutane endoskopische bilaterale Dekompression mit einseitigem Zugang bei lumbaler Spinalkanalstenose

The present protocol describes the steps and the key points of lumbar endoscopic unilateral laminotomy for bilateral decompression, LE-ULBD. This technique is used to treat degenerative lumbar spinal stenosis. The paramount advantage is that LE-ULBD provides an unparalleled clear visualization of the surgical field while reducing surgical-related trauma.Endoscopic spine surgery was initially used for lumbar disc herniation. However, it had evolved dramatically in recent years with the rapid development of endoscopic equipment and technological innovations. We have always been committed to broaden the scope of indications of spinal endoscopic technique.For example, we are developing percutaneous full-endoscopic C2 ganglionectomy to treat intractable occipital neuralgia.
