Overview and Prevention of Complications During Biportal Endoscopic Lumbar Spine Surgery

Abstract

Unilateral biportal endoscopic spine surgery (UBESS) is a minimally invasive surgical technique that has gained popularity for its potential benefits in various spinal lesions. It involves 2 small incisions, providing wide and clear endoscopic visualization, and causes less soft tissue damage than open surgery. UBESS offers flexibility and versatility in approaching different spinal disorders, including decompression of the spinal cord and root in the cervical or thoracic spine, as well as lumbar discectomy and spinal stenosis. One of the strengths of UBESS is its similarity to microscopic techniques, allowing for 2-handed endoscopic surgery. This familiarity makes it easier for surgeons to adopt endoscopic techniques and overcome the learning curve associated with spine endoscopy. However, some potential complications are associated with biportal endoscopic spine surgery, including dural tear, epidural hematoma, infection, incomplete surgery, and neural injury. Although the overall incidence of these complications is relatively low, it is important for clinicians to be aware of them and understand preventive methods. © 2023 Korean Minimally Invasive Spine Surgery Society.
