Recently, the percutaneous endoscopic lumbar interbody fusion (PELIF) technique has become the most representative minimally invasive technique in spinal surgery. PELIF is widely used in the treatment of various degenerative diseases of the lumbar spine. However, this technique has a long learning curve with adverse consequences for the patient if the surgeon is unsure of the indications and contraindications of this technique. There is currently no expert consensus on PELIF in spinal surgery in China. To standardize the application of this technique in various diseases of the lumbar spine in China, the Chinese Study Group of Minimal Invasive Spinal Surgery, Chinese Association of Spine and Spinal Cord, and Chinese Study Group for Lumbar Spine, Chinese Association of Spine and Spinal Cord, of the Chinese Association of Rehabilitation Medicine have taken the lead in developing this Chinese expert consensus on the application PELIF through a modified Delphi survey study method for the reference of our colleagues. The consensus covers the following aspects of the PELIF: indications and contraindications, advantages and disadvantages, preoperative evaluation, anesthesia methods and surgical procedures, treatment and prevention of complications, and postoperative follow-up.

近年来，脊柱内镜辅助下腰椎椎体间融合术（PELIF）已成为脊柱外科最具代表性的微创技术，被广泛应用于各类腰椎退行性疾病的治疗之中。然而，该技术具有较长的学习曲线，且手术医生对该技术的适应证和禁忌证把握不准时，可能会给患者带来相应的不良后果。目前我国脊柱外科专业尚无脊柱PELIF技术相关专家共识。为规范该技术在国内腰椎各类疾病中的应用，由中国康复医学会脊柱脊髓损伤专业委员会脊柱微创学组及脊柱脊髓专业委员会腰椎研究学组牵头，通过改良Delphi调查研究法制定了本共识，以供广大同道参考。本共识内容包括PELIF技术的适应证与禁忌证、优势和劣势、术前评估、麻醉方式及手术操作、并发症处理及预防和术后随访。.
