Comparision of biportal endoscopic and microscopic decompression in treatment of lumbar spinal stenosis: A comparative study protocol

Background: Microscopic bilateral decompression (MBD) has been suggested as an alternative to open laminectomy and fusion. Recently, percutaneous biportal endoscopic decompression (PBED) has begun to attract attention. The purpose of this retrospective study was to evaluate postoperative pain, functional disability, symptom reduction and satisfaction, and specific surgical parameters between the MBD and PBED techniques in patients with lumbar spinal stenosis (LSS). Methods: A retrospective review of LSS patients performed with MBD or PBED technique between May 2015 and June 2018 was conducted. Institutional review board approval in People's Hospital of Ningxia Hui Nationality Autonomous Region was obtained prior to conducting chart review and analysis. We received informed consent from all patients before surgery. The primary outcomes assessed were the preoperative to postoperative changes in leg/back pain and disability/function, patient satisfaction with the procedure, and postoperative quality of life. The secondary outcomes including duration of postoperative hospital stay, time to mobilization, postoperative analgesic use, complication rates, and baseline patient characteristics were prospectively collected. Results: The hypothesis was that the PBED technique would achieve better clinical outcomes as compared to the MBD technique in LSS.

Authors: Du WJ, Wang J, Wang Q, Yuan LJ, Lu ZX Abstract Context/objective: At present, there is no consensus on the most effective surgical method for treating symptomatic lumbar spinal stenosis (LSS). Total laminectomy, which is frequently used at this time, destroys the posterior midline structure, causing many postoperative complications. We have designed a new surgical approach instead of total laminectomy. In this paper, we aimed to describe the surgical method of endoscopic modified total laminectomy for lumbar spinal stenosis as well as to explore its early efficacy.Participants: Patients with symptomatic LS...

Conclusion: Decompressive laminectomy without fusion effectively managed LSS. It reduced patients' use of pain, anxiety, and antidepressant medications. In addition, we found that increased preoperative BMIs contributed to poorer postoperative outcomes (e.g., ODI values). PMID: 32123615 [PubMed]

Conclusions: Both microdecompression and wide open laminectomy with posterior stabilization were effective in treatment of multilevel lumbar spinal stenosis with superior results of microdecompression regarding less back pain postoperatively with less blood loss and soft tissue dissection. Clinical trial number: NCT04087694. PMID: 31827656 [PubMed - in process]

This study aimed to investigate the gender difference in pre- and postoperative health-related quality of life (HRQOL) in patients who have had decompression surgery for lumbar spinal stenosis (LSS). Overview of Literature: Gender differences may contribute to variations in disease presentations and health outcomes. The influence of gender on pre- and postoperative HRQOL in spinal disorders remains unclear. Methods: We reviewed 125 patients (79 men and 46 women) who had lumbar spinous process splitting laminectomy (LSPSL) for LSS. We assessed the following clinical information: Japanese Orthopedic Association (JOA)...

Conclusions: Endoscope-assisted and microscope-assisted tubular discectomies resulted in similar clinical outcomes for LDH, while the microscope-assisted surgery may relate to better recovery rate for LSS, less surgical time, and less intraoperative dural tear. PMID: 31179327 [PubMed - in process]

J Neurol Surg A Cent Eur Neurosurg DOI: 10.1055/s-0038-1655760 Background Lumbar spinal stenosis (LSS) and low-grade degenerative spondylolisthesis are frequently associated with facet joint degeneration, considered the main cause of low back pain. Surgery is the treatment of choice in patients affected by LSS unresponsive to conservative treatment. The aim of this study was to evaluate the clinical and radiologic outcome of patients treated with posterior decompression and transfacet fixation for single-level LSS and facet joint degeneration. Methods A total of 25 patients between May 2015 and June 2016 af...

ConclusionsThe 30-degreed endoscopy had the advantages of obtaining a wider view. Full endoscopic decompression using 30-degreed endoscopy allowed satisfactory result clinically and reduction of surgical infection. It could be alternative method of microscopic laminectomy.

Lumbar spinal stenosis is typically a degenerative condition that leads to compression of the spinal canal and lateral recess, resulting in leg pain and walking disability. Surgical management is indicated after failure of nonā€surgical management or rapidly worsening neurological impairment. The traditional approach is a laminectomy with foraminotomy and partial facetectomy but a newer minimally invasive option, unilateral laminectomy for bilateral decompression (ULBD), seems to demonstrate the better postoperative outcomes due to its unilateral exposure. ULBD involves a midline incision, opening the thoracolumbar fascia...
