Abstract

Background: Hypertrophy of the ligamentum flavum, degeneration of the discs, arthropathy of the facet joints, and osteophytes all contribute to the narrowing of the spinal canal and the compression of nerve roots, making lumber canal stenosis a prevalent medical condition.
Aim and objectives: To evaluate the efficacy of endoscopic lumbar decompression in the treatment of patients presenting with secondary single-level lumbar canal stenosis.
Patients and methods: This prospective study was carried out on 40-patients who underwent endoscopic lumbar decompression for lumbar canal stenosis, at Al-Azhar University Hospitals(Sayed Galal and Al-Hussien) during September 2022 till September 2024.
Results: In our study, the 20 patients with unilateral canal stenosis, the Denis pain score preoperatively ranged between 4 and 5 with a mean of 4.35; postoperatively, the Denis pain score ranged between 1 and 3 with a mean of 1.3. Among the 20 patients with bilateral canal stenosis, the Denis pain score preoperatively ranged between 4 and 5, with a mean of 4.45; postoperatively, pain ranged between 1 and 4, with a mean of 1.95. In the 20 patients of unilateral canal stenosis, we achieved 16(80%) patients with Denis's score-1(which is the best score, meaning no pain). In the 20 patients with bilateral canal stenosis, 11(55%) patients had Denis's score 1.
Conclusion: The best approach to treating lumbar canal stenosis involves careful planning before surgery, during the procedure, and in the recovery period afterwards. The majority of patients with lumbar spinal stenosis undergo a laminectomy as their treatment. Due to its advantages of less stress, less bleeding, and faster recovery, endoscopic spinal surgery has lately become frequently utilized to treat various kinds of lumbar stenosis.
