Meta-Analysis on Microdiscectomy and Sequestrectomy for Lumbar Disc Herniation.

Area of Science:

• Neurosurgery
• Orthopedics
• Pain Management

Background:

• Lumbar disc herniation (LDH) is a prevalent cause of low back pain, particularly affecting individuals aged 24-45.
• Surgical interventions like microdiscectomy and sequestrectomy are common treatments for LDH.

Purpose of the Study:

• To quantitatively evaluate and compare the efficacy of microdiscectomy versus sequestrectomy for treating LDH.
• To provide evidence-based information for clinical decision-making in LDH surgical management.

Main Methods:

• A meta-analysis was conducted on randomized controlled studies comparing microdiscectomy and sequestrectomy for LDH.
• Studies were systematically retrieved from major databases based on predefined inclusion and exclusion criteria.

Main Results:

• Microdiscectomy demonstrated a statistically significant improvement in low back pain visual analog scale (VAS) scores (SMD = 0.86, P = 0.01).
• No significant differences were observed in the re-operation rates (OR = 0.85, P = 0.60) or neuropathic pain VAS scores (SMD = 0.51, P = 0.14) between the two surgical methods.
• Sequestrectomy showed a superior analgesic usage rate compared to microdiscectomy.

Conclusions:

• Both microdiscectomy and sequestrectomy yield favorable outcomes for LDH treatment.
• Microdiscectomy offers better relief for low back pain, while sequestrectomy is associated with lower analgesic usage.
• The selection of surgical technique should be individualized based on patient-specific factors and clinical context.
