A retrospective review involving 307 consecutive cases of lumbar disc herniation managed by posterolateral endoscopic discectomy was conducted. ⋯ The surgical outcome of posterolateral endoscopic discectomy for lumbar disc herniation is comparable with that for the traditional open transcanal microdiscectomy. Intracanal and extracanal herniations, reherniations, and incidental lateral recess stenosis can be addressed by the same approach.
