Abstract:
Objective:To investigate the safety and efficacy of the modified transcutaneous endoscopic spine system (TESSYS) with full visual foramen plasty and percutaneous endoscopic discectomy (PTED) in the treatment of lumbar disc herniation and lumbar spinal stenosis.Methods:A case-control study was conducted to analyze the clinical data of 68 patients with single segment lumbar disc herniation and lumbar spinal stenosis treated with visual endoscopic foraminal plasty and modified TESSYS technique and intervertebral foraminal fusion from April 2020 to March 2021. According to the operation method, 38 cases were divided into two groups: pted group (38 cases) and TLIF group (30 cases). Independent sample t-test was used to compare the incision length, bleeding volume, operation time, time to go down and hospital stay between the two groups. Visual analog scale (VAS) scores and Oswestry disability index (ODI) scores were measured repeatedly. The differences between preoperative and postoperative 7 days and 1, 3, 6 months were analyzed and compared by generalized estimation equation. Rank sum test was performed in combination with the modified MacNab standard in the last follow-up. The excellent and good rate was compared between groups χ 2. Test and evaluate the curative effect. Results:The postoperative follow-up was 8.5-14.0 months. The incision length (1.25±0.33) cm, operation time (119.45±14.95), blood loss (24.03±8.62) mL, downtime time (1.42±0.50) d, and hospital stay (3.39±0.55) d in the PTED group were all higher than those in the TLIF group ((14.37±2.91) cm, (140.53±16.16) min, (158.00±51.35) mL, (3.20±0.96) d, (7.33±0.55) d) had obvious advantages ( t values were 24.56, 5.57, 14.13, 9.20, and 29.48, respectively; all P<0.001). The VAS scores and ODI scores of the two groups after operation were significantly improved compared with those before operation (all P<0.001), and with the passage of time, the VAS scores and ODI scores of the two groups of patients from 7 days to 6 months after operation by month were significantly decreased ( P<0.001). However, there was no significant difference between the two groups in VAS score from 1 week to 6 months after operation: P7d=0.997, P1 month=0.139, P3 month=0.057, P6 month=0.539, all P>0.05. There was no significant difference in ODI scores between time points (ODI: P7d=0.278, P1 month=0.442, P3 month=0.963, P6 month=0.278, all P>0.05). There was no significant difference between the two groups in terms of clinical efficacy and excellent and good rate evaluated by modified MacNab criteria at the last follow-up ( Z=0.09, P=0.927; χ 2=0.92, P=0.761). Conclusion:The short-term curative effect of full visual endoscopic foraminal plasty and modified TESSYS technique in the treatment of single level lumbar disc herniation and lumbar spinal stenosis is close to that of classical foraminal interbody fusion, and has certain advantages.
