Abstract

Objectives: To evaluate the outcomes of endoscopic decompression surgery for lumbar spinal stenosis at the L4-L5 level. Methods: This was a prospective, longitudinal, descriptive study conducted on 40 patients with L4-L5 lumbar spinal stenosis who underwent endoscopic decompression surgery at Viet Duc Friendship Hospital from January 2022 to January 2025. Results: Among the 40 patients in the study, the male/female ratio was 1.2/1, and the average age was 41.3 ± 8.3 years. All patients presented with lower back pain radiating to both legs, and neurogenic claudication was present in 82.5%. On MRI, central disc herniation was the most common cause of spinal stenosis, accounting for 77.5% of cases. Surgical characteristics included: an average operative time of 91.2 ± 34.2 minutes and an average hospital stay of 1.8 ± 0.2 days. Intraoperative complications included one case of dural tear. Both VAS and ODI scores showed significant improvement postoperatively compared to preoperative values. Conclusion: Endoscopic decompression for lumbar spinal stenosis is a minimally invasive intervention that is relatively safe, with few complications and provides very good results.
