Abstract：Objective To investigate the clinical effects and safety of transforaminal percutaneous endoscopic lumbar discectomy ( TF-PELD ) in the treatment of lumbar disc heniation ( LDH ). Methods The clinical data of 70 patients with LDH, admitted from January 2016 to February 2017, were analyzed retrospectively. Among them, 34 patients were treated with TF-PELD ( observation group ) and 36 patients were treated with open surgery ( control group ). After a follow-up of 6 months, the follow-up rate was 100%. The surgical indexes and treatment effects were evaluated and analyzed. Results The operative time of the observation group was significantly longer than that of the control group[(65.3 ± 7.2)min vs.(58.4 ± 6.4)min](P<0.05).The amount of bleeding[(47.3 ± 8.5)ml vs. ( 142.4 ± 12.3 ) ml ] was significantly less than those in the control group ( P < 0.05 ). The time for getting out of bed [(1.6 ± 0.5)d vs.(13.4 ± 2.4)d]and hospital stay[(4.9 ± 1.5)d vs.(16.2 ± 3.9)d]were significantly shorter than those in the control group ( P < 0.05 ). The VAS and ODI scores 3 months and 6 months after operation in both groups were significantly lower than those before operation with statistically significance ( P < 0.05 ). The VAS scores in the observation group 3 months after operation(2.41 ± 0.82 vs.4.34 ± 0.93)and 6 months after operation(1.61 ± 0.56 vs. 2.17 ± 0.78 ) were significantly lower than those in the control group with statistical significance ( P < 0.05 ). The ODI scores of observation group 3 months after operation(23.27 ± 7.79 vs. 35.47 ± 8.24)and 6 months after operation ( 14.45 ± 3.47 vs. 18.66 ± 5.18 ) were significantly lower than those in control group with statistical significance ( P < 0.05 ). The excellent and good rates of MacNab in observation group and control group were 91.18% and 69.44% respectively. The differences were statistically significant ( P < 0.05 ). Conclusions TF-PELD is safe and effective with quick recovery. It causes less complications in the treatment of LDH.
