Abstract:
【Objective】 To compare the clinical efficacy of percutaneous transforaminal endoscopic decompression （PEID） and percutaneous interlaminar endoscopic decompression （PETD） in the treatment of L
5 -S1 lateral recess stenosis. 【Methods】 We selected the patients in our center diagnosed with L5 -S1 lateral recess stenosis from March 2018 to October 2019 and divided them into Group A and Group B according to the principle of prospective， single-blind， and randomized control （A： PETD； B： PEID）. The operation was performed by the same senior surgeon with mature spinal endoscopy technology. We recorded the basic information， operation duration， usage count of C-arm， hospital stay， VAS score and ODI index of lower back and lower limbs before operation and 3 days， 1 month， 1 year and the last follow-up after the operation， and the operative excellent and good rates （the last follow-up）. The angle of bony lateral recess was measured during pre- and postoperative CT. 【Results】 A total of 95 patients （A： n=48； B： n=47） successfully completed the operation and were followed up for at least 1 year. The two groups did not significantly differ in age， gender， hospital stay， or complication by lumbar intervertebral disc herniation， but PEID group had significantly shorter operation duration and fewer usage counts of C-arm （P<0.001）. VAS score of lower back and lower limbs， and ODI index were significantly reduced at 3 days，1 month， 1 year and the last follow-up after the operation， with no significant difference between the two groups at the same time； no statistical difference was found between the two groups in operative excellent and good rates at the last follow-up （P>0.05）. The postoperative bony side recess angle was significantly improved （P<0.05）， while there was no significant difference in either pre- or postoperative bony side recess angle between the two groups （P>0.05）. 【Conclusion】 Both PEID and PETD are effective strategies in the treatment of L5 -S1 lateral recess stenosis and can achieve good clinical outcomes.
