| Objective To analyze the efficacy and its influencing factors of limited decompression with rear route diskoscope in the treatment of lumbar spinal stenosis. Methods Eighty senile patients with lumbar spinal stenosis ever treated in our hospital from Apr 2010 to Apr 2015 were collected and randomly divided into the open treatment group and the diskoscope treatment group, 40 cases in each group. The blood loss, Nakai score, operation time and hospitalization time between the two groups were compared. Results The operation time and hospitalization time in the open treatment group were much longer, and the blood loss was much higher than those in the diskoscope treatment group, with significant differences between them (P<0.05). The excellent and good rate of the open treatment group was 77.5%, which was slightly higher than that of the diskoscope treatment group (70%), but there was no significant difference (χ2=0.581, P=0.446). The influencing factors of surgical outcome were walking distance, complications, and preoperative JOA scores. Conclusion In the senile patients with lumbar spinal stenosis, the treatment of limited decompression with rear route diskoscope shows equivalent clinical efficacy to the conventional open surgery, but its operation time and hospitalization time are much shorter and its blood loss is much lower, and its main influencing factors are walking distance, preoperative JOA scores, and postoperative complications. |
