Percutaneous endoscopic lumbar discectomy and microsurgical laminotomy : A prospective, randomized controlled trial of patients with lumbar disc herniation and lateral recess stenosis.

Background Sufficient decompression of the nerve root canal is still regarded as the method of choice when operating on patients with lumbar disc herniation (LDH) with lumbar lateral recess stenosis; however, tissue-sparing procedures are becoming more popular. Endoscopic techniques offer advantages and the benefits of rehabilitation, which have become the standard in many surgical operations when operating on the spine. A significant issue has been the upgrading of instruments to provide enough bone resection under continuous visual control.
