Background:
Transforaminal endoscopic spine system (TESSYS) has the advantages of small trauma, rapid recovery, early out-of-bed activity and fewer postoperative complications in lumbar disc herniation (LDH) surgery. However, whether TESSYS would show a better curative effect than traditional open discectomy is not certain.
Methods:
Related clinical trial reports were collected from PubMed, Embase, Cochrane Library as well as China National Knowledge Infrastructure databases. After careful screening, the enrolled studies were evaluated by systematic review and meta-analysis using Revman v5.2 and STATA v11.
Results:
Using visual analogue scale as assessment index, TESSYS has a better operation effect than open discectomy only at 1 and 12 months after operation, the pooled standard mean differences were -0.289 (95% confidence interval (CI) -0.518 to 0.060, P = 0.013) and -0.18 (95% CI -0.34 to 0.03, P = 0.022). When using the Japanese Orthopaedics Association assessment index, a better operation effect of TESSYS was shown only at 3 months after operation, standard mean difference -0.394 (95% CI -0.678 to 0.110, P = 0.007). There were no obvious differences between TESSYS and open discectomy in Oswestry disability index assessment.
Conclusions:
TESSYS seems to display an equal operation effect with traditional open discectomy.
