OBJECTIVE: The target of this retrospective examine was to judge the medical feasibility and security of percutaneous endoscopic decompression by uniportal, unilateral strategy for the lumbar canal or lateral recess stenosis.
METHODS: The process was carried out with endoscopic devices in the identical manner as with typical microscopic laminotomy and flavectomy. Scientific outcomes (VAS, ODI, modified MacNab standards) have been evaluated. Surgical outcomes together with operative time, hospital keep and issues have been additionally investigated.
RESULTS: A complete of 213 sufferers (232 lumbar ranges) have been decompressed for spinal canal or lateral recess stenosis (Unilateral laminotomy: 80; Bilateral laminotomy: 152). The imply follow-up interval was 26.45 months. The imply VAS for leg ache, and again ache and the imply ODI improved from eight.24, 5.35, and 67.eight% at baseline to 1.93 (P < zero.001), 2.05 (P < zero.001), and 17.14 % (P < zero.001) at last follow-up, all respectively. Primarily based on the modified MacNab standards, glorious or good outcomes have been obtained in 93.eight % of the sufferers. Common operation time was 105.three±56 minutes. Within the late interval of the training curve, the imply operation time was shortened by two thirds, and the imply hospital keep was 2.45 days. There have been twelve instances of transient postoperative dysthesia, three instances of motor weak point and 6 instances of dura tear. No affected person developed postoperative an infection, hematoma or wanted for revision surgical procedure for incomplete decompression.
CONCLUSION: Percutaneous endoscopic decompression by uniportal, unilateral strategy is a protected, clinically possible and efficient surgical approach for the therapy of lumbar stenosis.
