Percutaneous Full Endoscopic Bilateral Lumbar Decompression of Spinal Stenosis Through Uniportal-Contralateral Approach: Techniques and Preliminary Results

Abstract

The preliminary result of this uniportal-contralateral PESLD technique is encouraging (96% demonstrated a good-to-excellent outcome), and the procedure is safe. However, we need long-term follow-up and a more detailed study for more accurate results of this technique.

Degenerative central lumbar spinal stenosis: Is endoscopic decompression through bilateral transforaminal approach sufficient?

“…In our cases, there were no cases of cerebrospinal uid leakage, infection, or negative consequences such as revision surgery. Three patients of transient postoperative dysthesia were present in this study, similar to other literature [16,27,[31][32][33].Postoperative dysthesia is considered to be related to the burning of the radiofrequency electrode around the nerve root, and highintensity radiofrequency bipolar should be avoided around the nerve structure. The continuous intraoperative saline ushing provides a safer space for the differentiation of the nerve structure from the surrounding structure during endoscopic decompression.…”

“…In this study, the average age of patients was 72 years, and 80.9% (38/47) of patients combined with various medical diseases. The average age and the incidence of preoperative medical diseases were higher than other reports, but ultimately those clinical parameters such as VAS and ODI showed signi cant improvements [16,27,[31][32][33].These results indicate that the advantages of endoscopic decompression through bilateral transforaminal approach not only have a good cosmetic appearance and anesthesia tolerance, but also can quickly and effectively relieve pain. The above advantages are mainly attributed to the minimally invasive endoscopic procedure.…”

“…The advantages of the transforaminal approach can better deal with lateral and ventral compression of the dural sac. Although the operation time in this study is slightly higher than other decompression methods [16,27,[31][32][33], the whole spinal canal including bilateral intervertebral foramina, lateral recesses and central spinal canal can be effectively treated through bilateral transforaminal approach. And bilateral nerve roots and dural sac can be fully decompressed which ensure the surgical decompression effect.…”

A Degenerative Intraspinal Cyst Mimicking a Nerve Root: A Case Report on an Intraoperative Challenge

“…2 & Video 1). We used full endoscopic approach in this patient because interlaminar approach endoscopic surgery has already been established as a surgical option for spinal stenosis 5) . For that reason we decided to excise the cyst with full endoscopic surgery but due to adhesions the task became difficult as described above.…”

Full-endoscopic lumbar decompression versus open posterior interbody fusion for surgical treatment of stable lumbar disc herniation in patients over 65 years: A retrospective cohort study with 2-year follow-up

“…Full-endoscopic lumbar decompression (FELD) is a newly developed technique, which has been used in the treatment of LDH and LSS. With further development of PELD, FELD could achieve visualized satisfactory spinal decompression from dorsal to ventral and avoid the damage of posterior structures under local anesthesia [15], which made it a potential alternative for older patients. Nevertheless, to the best of our knowledge, few studies have described the safety and e cacy of FELD in treating older patients with LDH.…”
