Feasibility Study Of Percutaneous Endoscopic Interlaminar Discectomy Surgery Guided By Ultrasound

Objective:To explore the feasibility of IL-PELD(percutaneous endoscopic interlaminar discectomy)surgery using ultrasound to locate,puncture and placement channel instead of C-arm.Methods:Selected 50 patients with L5/S1 lumbar disc herniation who needed percutaneous endoscopic interlaminar discectomy treatment from August 2017 to October 2018.Among them,25 patients in the test group(mean age 53.4± 17.05 years old)guided by ultrasound,and 25 patients in the control group(mean age 52.2±15.63 years old)guided by C-arm.The accuracy,time and radiation dose of the test group and the control group were compared.Results:(1)The success rate of the test group and the control group was 100%,and the operation was successfully completed.(2)The time required for the puncture of the test group was increased compared with the control group(P<0.05).(3)The average radiation dose of the test group was significantly lower than that of the C-arm group(P<0.05).(4)In the test group,the average time required in the ?50-year-old group was longer than that in the <50-year-old group(P<0.05).(5)In the test group,patientsin the BMI?25 group were more likely to use more time to locate than the BMI <25 group(P < 0.05).Conclusion:1.When do the IL-PELD surgery,the ultrasound can instead of the C arm to locate and guide.2.The ultrasound can avoid radiation exposure,and it is easy to operate and safe.3.The ultrasound guidance is more suitable for patients with younger age and lower BMI index.
