Abstract
Traditionally, microscopic surgery is the gold standard surgical treatment for lumbar spine disease, including lumbar spinal stenosis (LSS) and lumbar disc herniation (LDH). However, the conventional posterior approach has disadvantages. Recently, unilateral biportal endoscopy (UBE) has been widely used in decompression surgery for LSS and LDH. The main advantages of UBE are the availability of a familiar and magnified surgical view and the independent movement of an endoscope and other instruments during surgery. These can help achieve complete neural decompression and improve neurological outcomes while preventing complications correlated with the conventional posterior approach. UBE is an endoscope-assisted spinal surgery that requires a series of working spaces with potential spaces. If these potential spaces can be converted into a working corridor, UBE guarantees similar indications as conventional spinal surgery and achieves minimal invasiveness. Also, UBE is a fluid-medium surgery, with an input of irrigating saline via the scopic portal and output via the working portal. Therefore, to prevent the risk of fluid-related complications, it is important to maintain water outflow. This chapter assesses the surgical techniques of the posterior approach and the strategies for preventing complications in patients undergoing UBE for LSS and LDH.
