Comparision of Endoscopic Discectomy and Microdiscectomy for the Treatment of Lumbar Spinal Stenosis

Endo-Surgi Plus endoscopic surgery, as a new type of percutaneous endoscopic lumbar discectomy (PELD), features a larger working channel and represents an optimized single-channel endoscopic technique. However, it still has the limitations inherent in single-channel endoscopy.

Unilateral biportal endoscopic discectomy (UBE) is characterized by its separate endoscopic and working channels, and the ability to use traditional open instruments, making it a convenient and versatile technique. It is a commonly used spinal endoscopic surgery in clinical practice.

Microdiscectomy (MD) is a mature minimally invasive technique that uses a microscope to treat lumbar spinal stenosis. As early as 1999, prospective randomized controlled studies confirmed that it has equally excellent clinical efficacy compared to open surgery, with less surgical trauma. It is currently the classic minimally invasive surgical approach for treating lumbar spinal stenosis.
