Abstract:

Objective To compare the clinicalefficacy of electromagnetic⁃navigation guided transforaminal endoscopic spinal discectomy（See electromagnetic⁃navigation endoscopic spinal surgery system，SEESSYS）and C⁃arm fluoroscopy guided transforaminal endoscopic spinal discectomy（Transforaminal endoscopic surgical system，TESSYS）in the treatment of lumbar disc herniation. In addition，the use of electromagnetic navigation technology in the application of percutaneous endoscopic lumbar discectomy will be discussed for its safety and benefits. Methods From September to December 2018，a retrospective analysis was performed on 44 cases of LDH patients who had surgical therapy in our hospital. According to the varied surgical procedures，they were classified into two groups：SEESSYS and TESSYS，with 22 cases in each group. The two groups were compared on perioperative indi⁃ cators such as operation time（working tube placement time and endoscopic decompression time），intraoperative fluoroscopy timings，and length of hospital stay. The surgical complications were also recorded. Results The work⁃ ing tube placement time，total operation time and the number of intraoperative C⁃arm fluoroscopy of the SEESSYS group were significantly shorter than those of the TESSYS group（P < 0.01），however，there were no significant difference in the time of endoscopic decompression and the length of hospital stay between the two groups（P > 0.05）. The postoperative ODI，back and leg VAS were significantly lower than those of pre⁃operation in both groups（P < 0.01），but there was no significant difference in the VAS and ODI scores between the two groups（P > 0.05）. At the 2⁃year follow⁃up，the excellent and good rate of SEESSYS group was 95.5%，and TESSYS group was 90.91%.Conclusions At a 2⁃year follow⁃up，the SEESSSYS has a satisfactory clinical effect when compared to traditional C ⁃ arm fluoroscopy guidance. Furthermore，electromagnetic navigation aids in reducing radiation exposure to medical personnel during the procedure，as well as effectively shortening the working tube placement and the over⁃ all operation time.
