title: Working channel endoscope in lumbar spine surgery.
abstract: Percutaneous endoscopic lumbar discectomy (PELD) is a well established modality in the treatment of patients with herniated lumbar discs. Since the time of its inception towards the end of 20th century, this technique has undergone significant modifications. With better understanding of the patho-anatomy and development of instrumentation the indications for PELD are on the rise. In the modern era of knowledge exchange there have been considerable variations among different endoscopic surgeons about classical indications and the implications of a particular technique pertaining to those indications. During last 15 years of experience in practicing endoscopic surgery, Choi has published many articles, regarding the techniques of PELD, across many scientific journals. In our practice there has been considerable shift from central debulking to discectomy to selective fragmentectomy. With further advancements the span of this technique is definitely on the rise. Here, we wish to share all the published data along with my current practice trends in more precise manner to help newer endoscopic spine surgeons understand the implications and limitations of a working channel endoscope in lumbar spine pathologies.
