Expert Consensus on the Treatment of Lumbar Spinal Stenosis Using One-hole Split Endoscopy Technique
The incidence of lumbar spinal stenosis(LSS)is increasing year by year,which has seriously affected the physical health and quality of life of middle-aged and elderly people.At present,the commonly used methods for spinal endoscopic treatment of LSS include unilateral biportal endoscopy(UBE),One-hole Split Endoscopy(OSE),and percutaneous transforaminal endoscopic discectomy(PTED).The trauma of OSE for LSS is smaller than that of UBE(one surgical pathway).OSE has more thorough decompression of the spinal canal and nerve root than PTED.OSE has the advantages of short surgical operation time,less intraoperative bleeding,less surgical trauma,and fast postoperative recovery.Although OSE technology has been successfully applied in clinical treatment for 4 years,its awareness and popularity are still insufficient.At present,there is a lack of expert consensus and guidelines for OSE treatment of LSS.To further improve the understanding and mastery level of OSE among spinal surgeons,Under the sponsorship of the Spinal Minimally Invasive Expert Committee of the Chinese Society of Traditional Chinese Medicine,the Orthopaedic Rehabilitation Professional Committee of the Chinese Rehabilitation Medicine Association,and the Spinal Surgery Expert Group of the Orthopaedic Physician Regular Assessment Professional Committee of the Chinese Medical Association,and with the cooperation of the Basic Medical Work Committee of the Shandong Geriatrics Association,OSE expert members refer to the guidelines recommended by the World Health Organization to develop methods,determine important clinical problems to be solved through investigation,and evaluate literatures published in the field of OSE,UBE,PTED.Based on current evidence-based medicine,recommendations were ultimately formed through Delphi voting and expert group discussions,covering the indications,contraindications,diagnosis,surgical methods,surgical procedures,postoperative rehabilitation considerations,and preoperative and postoperative evaluations of OSE.The aim was to provide clinical guidance and assistance for spinal surgeonswhen using OSE for LSSand to improve the diagnosis and treatment level of LSS spinal endoscopy in China.
