Visual analog scale (VAS) scores and Oswestry Disability Index (ODI) were analyzed preoperatively, postoperatively at 3, 6, 12, and 24 months, and at final follow-up. The modified MacNab criteria were used to assess clinical effects. All complications were recorded.Results: At a mean follow-up of 3 years, 24 patients with LSS who underwent repeat PELD were identified. The patients’ mean operative time was 122.3± 29.2 min, blood loss was 12.5± 5.3 mL, and mean hospital stay was 7.0± 1.9 days. VAS leg-pain score improved from 6.1± 1.0 to 2.0± 1.2 (P< 0.001), VAS back-pain score improved from 6.2± 0.8 to 2.1± 1.1 (P< 0.001), and ODI improved from 68.9± 6.0 to 20.9± 5.6 (P < 0.001). According to the modified MacNab criteria, the good-to-excellent rate was 83.3%. Postoperative complications, including hematoma, nerve root injury, and dural injury, developed in four patients.Conclusion: Repeat PELD for reoperation in patients with LSS has a good clinical effect, and is recommended in routine clinical practice. Careful intraoperative manipulation is recommended to prevent complications.Keywords: lumbar spinal stenosis, percutaneous endoscopic lumbar decompression, reoperation, complication
