RESUMO
Objective: To compare and analyze the effect of minimally invasive surgery and traditional open surgery in patients with spinal canal tumors, including intraspinal and extraspinal communication tumors. Methods: From 2017 to 2019, 31 patients (minimally invasive channel group) were included in the neurosurgery department of Huashan Hospital Affiliated to Fudan University, and 38 patients (open operation group) were selected as the control group. From the aspects of intraoperative condition, operative effect, postoperative muscle injury, postoperative complications, postoperative spinal stability, the minimally invasive access group and the open operation group were compared and analyzed. Results: The bleeding volume (70.2 ml±4.9 ml), operation time (164.7 min±16.0 min) and hospitalization days (9.5±2.5) in the minimally invasive access group were significantly lower than those in the open operation group (P<0.001). The creatine kinase CK (363.9 U/L±51.6 U/L) in the minimally invasive group was significantly lower than that in the open group (514.2 U/L±68.3 U/L) (P<0.001). According to Panjabi standard, the effect of spinal cord stability in minimally invasive group was significantly lower than that in open operation group (P<0.001), and the symptom improvement rate in minimally invasive group was significantly higher than that in open hand group (P<0.05). Conclusions: Compared with the open surgery, the amount of bleeding, the length of incision, the time of operation and the days of hospitalization were significantly shorter, the degree of muscle damage was also significantly reduced, the incidence of complications was lower, the impact of spinal stability was smaller, and the overall advantage was obvious.
