Prevalent endoscopic spine surgeries have shown limitations especially in spinal stenosis (Ahn in Neurosurgery 75(2):124-133, 2014). Biportal endoscopic surgery is introduced to manage central and foraminal stenosis with its wide range of access angle and clear view.
The authors provide an introduction of this technique followed by a description of the surgical anatomy with discussion on its indications and advantages. In particular, tricks to avoid complications are also presented.
Effective circumferential and focal decompression were achieved in most cases without damage to the spinal structural integrity with preservation of muscular and ligamentous attachments. The biportal endoscopic spinal surgery (BESS) may be safely used as an alternative minimally invasive procedure for lumbar spinal stenosis (Figs. 1 and 2).
常见的脊柱内镜手术已显示出局限性，尤其是在治疗腰椎管狭窄症方面（安，《神经外科学》75(2):124 - 133，2014年）。双门内镜手术因其广泛的进入角度和清晰视野而被引入用于治疗中央型和椎间孔型狭窄。
作者首先介绍了该技术，随后描述了手术解剖结构，并讨论了其适应症和优势。特别地，还介绍了避免并发症的技巧。
在大多数情况下，实现了有效的环形和局部减压，且未损害脊柱结构完整性，同时保留了肌肉和韧带附着。双门内镜脊柱手术（BESS）可安全地用作腰椎管狭窄症的一种替代微创手术（图1和图2）。
