Clinical Report: Utilization of Unilateral Biportal Endoscopy for Spinal Tumors

Overview

This study evaluates the safety and efficacy of unilateral biportal endoscopy (UBE) for treating non-aggressive benign spinal tumors.

Background

Non-aggressive benign spinal tumors, while rare, can lead to severe clinical consequences due to their anatomical location. Surgical intervention is often necessary to alleviate symptoms and prevent complications. Traditional surgical methods can result in significant trauma and extended recovery times, highlighting the need for minimally invasive techniques like UBE.

Data Highlights

ParameterValue
Mean Operative Duration (min)77.5 ± 21.2
Mean Blood Loss (mL)17.5 ± 11.7
Follow-up Duration (months)16.6 ± 5.4

Key Findings

  • All 14 patients successfully underwent UBE surgery.
  • Mean operative duration was 77.5 minutes with a mean blood loss of 17.5 mL.
  • Significant improvement in VAS scores at all postoperative timepoints (P < 0.05).
  • No tumor recurrence was observed during follow-up.
  • All patients resumed normal daily activities post-surgery.

Clinical Implications

UBE presents a minimally invasive option for managing non-aggressive benign spinal tumors.

Conclusion

UBE is a viable surgical technique for non-aggressive spinal benign tumors.
