Abstract:Objective To investigate the effect of microscopically assisted lumbar discectomy (MSLD) in the treatment of lumbar disc herniation (LDH). Methods One hundred and five cases of LDH admitted to Yuebei People′s Hospital from February 2016 to April 2018 were selected. The patients were divided into percutaneous intervertebral disc percutaneous endoscopic lumbar discectomy (IL-PELD) group (n = 52, given IL-PELD) and MSLD group (n = 53, given MSLD). The operation time, intraoperative bleeding volume, incision length, fluoroscopy times, hospitalization time and complication rate were recorded. The clinical efficacy of the two groups after treatment was observed. The visual analogue score (VAS) and Osweatry dysfunction index (ODI) were recorded before operation, 1 d, 1 month, 3 months and 6 months after operation. Results There was no significant difference in incision length and hospitalization time after operation between two groups (P > 0.05). The operation time of MSLD group was longer than that of IL-PELD group; the amount of bleeding, the number of fluoroscopy in MSLD group were less than those in IL-PELD group; the incidence of complication in MSLD group was lower than that in IL-PELD group (P < 0.05). The total effective rate of two groups was not statistically significant (P > 0.05). There was no significant difference in VAS and ODI scores between two groups before operation, 1 d after operation, 1 month after operation, 3 months after operation and 6 months after operation at the same period (P > 0.05). The VAS and ODI scores of two groups were lower than those 1 d, 1 month, 3 months and 6 months after the operation, and presented a trend of decrease with time (P < 0.05). Conclusion Compared with the traditional operation, MSLD can effectively reduce the amount of bleeding, the number of fluoroscopy and the incidence of complications. It is worthy of further clinical application.
