Abstract：Objective To prospectively study the surgical strategy, safety and early clinical outcomes of percutaneous full-endoscopic lumbar lateral recess decompression through interlaminar approach. Methods From April 2012 to April 2013, 37 patients with lumbar lateral recess stenosis with or without calcified disc herniations or osteophytes on the posterior aspect of the vertebral body were treated with percutaneous full-endoscopic lumbar lateral recess decompression through interlaminar approach. The lumbar MRI images were reexamined at 2 days and 3 months after the operation to evaluate decompression of the lateral recess and resection completeness of the prolapsed disc material. The Visual Analogue Scale ( VAS ) scores of low back pain and sciatica and Oswestry Disability Index ( ODI ) scores were recorded preoperatively and at 3, 6 and 12 months after the operation, and the statistically signiifcant differences were compared. The MacNab scores were evaluated at 12 months after the operation. Results All the operations were successfully completed without conversions to other surgical techniques. The average operation time was 50min ( range: 25-80 min ). Only 1 case of reoccurrence was revised with percutaneous transforaminal endoscopic discectomy. One case of facet syndrome was relieved by medial branch block. No nerve injuries, infections or other complications were noticed. The VAS score of low back pain was decreased from ( 24.4±14.0 ) points preoperatively to ( 7.5±6.9 ), ( 5.8±6.0 ) and ( 5.6±8.1 ) points at 3, 6 and 12 months after the operation respectively. The VAS scores of sciatica was decreased from ( 76.1±9.9 ) points preoperatively to ( 3.6±6.4 ), ( 1.7±3.8 ) and ( 1.7±3.8 ) points at 3, 6 and 12 months after the operation respectively. The ODI score was decreased from ( 74.7±10.0 ) points preoperatively to ( 27.7±5.3 ), ( 10.1±5.3 ) and ( 14.4±4.8 ) points at 3, 6 and 12 months after the operation respectively. The postoperative ODI and VAS scores were signiifcantly decreased at each time point when compared with the preoperative scores. According to the MacNab scores at 12 months after the operation, there were 20 excellent cases, 15 good cases, 1 fair case and 1 poor case. Conclusions Percutaneous full-endoscopic lumbar lateral recess decompression through interlaminar approach is a safe and rational minimally invasive spine surgery technique for lumbar lateral recess stenosis, with excellent short-term outcomes.
