Summary

This study shows that a minimally invasive endoscopic technique is a safe and effective option for treating symptomatic lumbar disc herniations (LDH). With practice, surgeons can reduce operating times and improve patient outcomes.

Area of Science:

  • Neurosurgery
  • Minimally Invasive Spine Surgery
  • Endoscopic Spine Procedures

Background:

  • Optimal management for symptomatic lumbar disc herniations (LDH) remains debated.
  • This study evaluates a video-assisted endoscopic intracanalicular technique for LDH.

Purpose of the Study:

  • To assess the feasibility and safety of a novel endoscopic approach for symptomatic lumbar disc herniations.
  • To compare early outcomes with established surgical methods.

Main Methods:

  • 11 patients with symptomatic LDH underwent endoscopic discectomy using the Vertebroscope System.
  • Procedures involved a 2 cm paramedian skin incision with a 30-degree viewing angle endoscope.
  • Mean follow-up was 12 months.

Main Results:

  • Mean operative time was 136.5 minutes, with significant reduction after initial cases (201 vs. 72 min).
  • Minimal blood loss (≤200 ml) and short hospital stays (mean 3 days) were observed.
  • Complications included one superficial infection, one conversion to open surgery, and one minor nerve root sleeve tear.

Conclusions:

  • The endoscopic technique offers minimally invasive benefits: reduced muscle trauma, direct lesion access, and enhanced visualization.
  • Surgical proficiency improves with practice, leading to decreased operative times.
  • This endoscopic discectomy is a safe and effective treatment for symptomatic LDH.
