Abstract：ObjectiveTo investigate the clinical effect of percutaneous transforaminal endoscopic discectomy(PTED)via the interlaminar approach in the treatment of lumbar disc herniation.Methods56 cases of lumbar intervertebral disc herniation treated in our hospital from March 2015 to March 2017 were selected,and the mathematical random list method was adopted,which was divided into control group and treatment group,with 28 cases in each group.In the control group,removal of nucleus pulposus by PTED,while in the treatment group,on the basis of the traditional surgery,nucleus pulposus was removed by median fenestration or transforaminal lumbar interbody fusion(TLIF).The operation time,total hospital stay,normal time of lumbar function recovery,total effectiveness rate,improvement of pain degree in visual analogue scale (VAS)and Oswestry disability index before and after operation,and the adverse reaction rate in the perioperative period were compared in the two groups.ResultsIn the treatment group,the operation time,total hospital stay,and normal recovery time of lumbar function were shorter than those in the control group(P＜0.05).]Improvement of pain degree(VAS)and Oswestry disability index before and after operation in the treatment group was superior to those in the control group (P＜0.05).The incidence of adverse reaction was 3.6%in perioperative period in the treatment group,which was lower than 21.4%in the control group with statistical significance(P＜0.05).ConclusionFor patients with lumbar disc herniation,on the basis of the traditional operation,implementation of median fenestration or TLIF for the removal of nucleus pulposus can improve the physiological function of the lumbar spine in a short time,maximally control the pain,shorten the therapeutic time,and reduce the adverse reaction,so as to increase the therapeutic effectiveness rate.
