The aim of this study was to investigate the short-term clinical effectiveness of PELD for HLDH with complete dural sac stenosis via an interlaminar approach.Methods: We retrospectively analyzed 56 patients diagnosed with HLDH with complete dural sac stenosis and treated with PELD via an interlaminar approach. Numerical rating scale (NRS), Oswestry disability index (ODI), and modified Japanese orthopedic association (mJOA) were used to evaluate preoperative conditions as well as outcomes at 1, 3, 6 and 12 months postoperatively. At the final follow-up, the clinical effects were evaluated using modified MacNab criteria.Results: All patients were followed for at least 12 months. At 1, 3, 6, and 12 months postoperatively, the NRS and ODI scores were significantly decreased, and the mJOA score significantly increased compared with preoperative results (P< 0.001). According to the Macnab criteria at the final follow-up, it was excellent in 42 patients (75%), good in 9 (16.1%), and fair in 5 (8.9%). The overall clinical satisfactory rate was 91.1%.Conclusion: Our study results suggest that percutaneous endoscopic interlaminar discectomy (PEID) is available for the treatment of HLDH with complete dural sac stenosis, whose benefits are rapid recovery, complete removal of the herniated disc, effective spinal canal decompression, fewer complications, and significant relief of clinical symptoms.Keywords: percutaneous endoscopic lumbar discectomy, percutaneous endoscopic interlaminar discectomy, huge lumbar disc herniation, complete dural sac stenosis, diffusion tensor imaging
