Abstract
Percutaneous biportal endoscopic surgery was used in two channels. One portal was used for endoscopy, and the other portal was used for working channel. And, general spinal operative instruments are available during procedures. The indication of biportal endoscopic approaches is same as microdiscectomy for lumbar disc herniation. Indications of biportal endoscopic discectomy include foraminal and extraforaminal herniated disc, highly migrated disc, and cauda equina syndrome huge disc herniation like microsurgery. Operation procedures of biportal endoscopic discectomy were similar with microsurgery. The surgical anatomical view of biportal endoscopic approaches is similar to the spinal microscopic anatomy. Additional discectomy for internal decompression can be achieved like microsurgery. We suggest that percutaneous biportal endoscopic lumbar discectomy may be an effective treatment for various types of lumbar disc herniation.
