Abstract: Objective To compare the curative effects of different spinal endoscopic surgery methods in the treatment of lumbar spinal stenosis. Methods 120 patients with lumbar spinal stenosis who were treated in Aksu City People's Hospital from January 2019 to October 2021 were prospectively selected as the research subjects, and the patients were divided into two groups according to the random number table method (60 cases in each group). The control group, the observation group who underwent unilateral dual-channel endoscopy. The surgery-related indicators,clinical efficacy,the Japanese Orthopaedic Association (JOA), the European Disability Index (ODI) and the incidence of complications were compared between the two groups. Results The operation time of the observation group was significantly shorter than that of the control group, the time of getting out of bed and the length of hospital stay were significantly longer than those of the control group (P<0.05). There was no significant difference in intraoperative blood loss between the observation group and the control group (P>0.05). The total effective rate of clinical treatment in the observation group was significantly higher than the control group (P<0.05); the JOA score of the observation group were higher than those of the control group, the ODI score of observafion up was lower in those of control group (P<0.05); The total incidence of complications in the observation was slightly lower than the control group, but the difference was notsignificant (P>0.05). Conclusion Compared with single-channel endoscopic technique, unilateral dual-channel endoscopic technique can shorten the operation time, improve clinical treatment effect, and improve movement disorders, and there is no difference in the safety of the two treatment methods, which can be used in clinical practice.
