Percutaneous Endoscopic Lumbar Discectomy (PELD)

This procedure is mostly performed when there is clear imaging evidence and endoscopic access is suitable, and can be performed under local or general anesthesia. A channel is usually established through the intervertebral foramen or interlaminar space, and a working cannula and endoscope are inserted. Under continuous perfusion and fluoroscopic guidance, the annulus fibrosus is incised, the protruding nucleus pulposus tissue is removed, and the compressed nerve root is loosened and decompressed. Bony or soft tissue stenosis is treated if necessary. After hemostasis and irrigation are completed, the instruments are withdrawn and the small incision is sutured. Postoperative early monitoring of pain, sensation, and muscle strength changes, and gradual recovery of activity, the goal is to relieve nerve compression and preserve spinal stability. The above is general health information, not medical advice; the specific information is subject to specialist assessment and hospital plan.
