[Research progress of different minimally invasive spinal decompression in lumbar spinal stenosis].

To review the application and progress of different minimally invasive spinal decompression in the treatment of lumbar spinal stenosis (LSS).The domestic and foreign literature on the application of different minimally invasive spinal decompression in the treatment of LSS was extensively reviewed, and the advantages, disadvantages, and complications of different surgical methods were summarized.At present, minimally invasive spinal decompression mainly includes microscopic bilateral decompression, microendoscopic decompression, percutaneous endoscopic lumbar decompression, unilateral biportal endoscopy, and so on. Compared with traditional open surgery, different minimally invasive spinal decompression techniques can reduce the operation time, intraoperative blood loss, and postoperative pain of patients, thereby reducing hospital stay and saving treatment costs.The indications of different minimally invasive spinal decompression are different, but there are certain advantages and disadvantages. When patients have clear surgical indications, individualized treatment plans should be formulated according to the symptoms and signs of patients, combined with imaging manifestations.对不同微创椎管减压术治疗腰椎管狭窄症（lumbar spinal stenosis，LSS）的应用及进展进行综述。.广泛查阅国内外应用不同微创椎管减压术治疗LSS的相关文献，对不同术式的优缺点及并发症进行综述。.目前微创椎管减压术主要包括经通道显微镜下腰椎管减压术、椎间盘镜下腰椎管减压术、经皮内窥镜下腰椎管减压术、单侧双通道脊柱内镜技术等。与传统开放手术相比，各微创椎管减压术均能减少手术时间、术中失血量及患者术后疼痛，进而减少住院时间并节省治疗费用。.不同微创椎管减压术适应证不同，但都存在一定优势和不足。当患者有明确手术指征时，需根据患者症状及体征，结合影像学表现，制定个性化治疗方案。.
