Abstract：Objective To describe and evaluate the indication and clinical outcomes of percutaneous endoscopic decompression ( PED ) techniques for single segmental lumbar spinal stenosis.Methods From September 2011 to August 2014, 67 cases ( 32 males and 35 females ) were treated with percutaneous endoscopic decompression surgery. The mean age was ( 61.3 ± 11.9 ) years. Forty-ifve cases were treated with interlaminar approach and the other 22 cases were with transforaminal approach. Visual analogue scale ( VAS ) and Oswestry disability index ( ODI ) were used for evaluation before and 3 days, 1 week, 1 month, 3 months and 6 months after surgery, and the clinical efficacy was evaluated by modified Macnab criteria.Results All cases were followed up for 6 - 14 ( 10.2 ± 2.2 ) months. The mean operation time was 83.5 min, blood loss was 25 ml. At the ifnal follow-up, VAS for back and leg, ODI score were signiifcantly improved than that of preoperative scores. According to MacNab, “excellent” was found in 49 cases ( 73.1% ), “good” in 12 cases ( 17.9% ), and “fair” in 6 cases ( 9.0% ), the rate of excellence and good was 91%.Conclusions Percutaneous endoscopic decompression surgery is effective for single segmental lumbar spinal stenosis, meanwhile, there are many advantages in reduced traumatization, rehabilitation period and the outcome is satisfactory. During the surgery, surgical approaches need to be adjusted according to the site of stenosis, which need high requirements of surgical equipment and techniques.
