[EXPERIENCE OF BIPORTAL ENDOSCOPIC DECOMPRESSION IN LUMBAR SPINAL STENOSIS].

Area of Science:

• Neurosurgery
• Orthopedic Surgery
• Minimally Invasive Procedures

Background:

• Lumbar spinal stenosis (LSS) is a common condition causing significant pain and disability.
• Traditional open surgery for LSS can involve substantial tissue trauma and prolonged recovery.
• Biportal endoscopy offers a minimally invasive alternative for spinal decompression.

Purpose of the Study:

• To analyze the treatment outcomes of biportal endoscopic decompression for lumbar spinal stenosis.
• To evaluate the efficacy and safety of this technique compared to open surgery.

Main Methods:

• Retrospective analysis of 62 patients who underwent biportal endoscopic decompression for lumbar spinal stenosis.
• Assessment of pain using the Visual Analogue Scale (VAS), patient satisfaction with the modified MacNab scale, and quality of life with the Oswestry Disability Index (ODI).
• Evaluation of perioperative data including surgery duration, hospital stay, blood loss, and complications; radiological assessment via MRI.

Main Results:

• Significant reduction in VAS scores for back pain (0.9±1.4) and leg pain (1.28±1.1) post-surgery.
• Low average blood loss (34.8±16.2 ml) and short hospital stay (2.9±1.3 days).
• Complications included 4 dural membrane punctate wounds and 1 linear wound requiring conversion to open surgery.

Conclusions:

• Biportal endoscopic spinal surgery is an effective treatment for lumbar spinal stenosis.
• It demonstrates advantages over open surgery, including reduced tissue trauma, less blood loss, and high patient satisfaction.
• The technique provides a wide surgical field for complete decompression and reduces infection risk through continuous irrigation.
