经皮脊柱椎间孔镜下应用BEIS技术治疗腰椎管狭窄症的临床疗效及安全性评价

Clinical efficacy and safety of BEIS in the treatment of lumbar spinal stenosis under percutaneous intervertebral foramen

目的研究经皮脊柱椎间孔镜下应用BEIS技术治疗腰椎管狭窄症的临床疗效和安全性。方法采用回顾性分析,研究对象为2019年1月至2020年1月泰州市人民医院入院的64例腰椎管狭窄症患者,按照治疗方法不同分为对照组(n=32)和研究组(n=32)。对照组选用经椎间孔入路腰椎椎体间融合术治疗,研究组选用BEIS技术行经皮椎间孔镜下髓核摘除射频消融术治疗。比较2组患者手术相关指标(术中出血量、手术时间、术后卧床时间、住院时间),手术后3个月腰腿疼痛评分、腰椎功能障碍评分及并发症发生率。结果研究组患者的术中出血量、手术时间、术后卧床时间、住院时间分别为(61.67±5.63)mL、(59.91±9.73)min、(2.31±1.58)d、(3.94±1.36)d,均显著低于对照组[(326.82±17.46)mL、(118.34±20.16)min、(6.14±1.65)d、(8.41±3.32)d],差异有统计学意义(P<0.05)。观察组患者术后腰腿疼痛评分、腰椎功能障碍评分与并发症发生率分别为(1.52±0.59)分、(7.48±2.21)分、3.13%,均明显低于对照组[(3.16±0.78)分,(18.54±7.17)分,21.87%],差异有统计学意义(P<0.05)。结论经皮脊柱椎间孔镜下应用BEIS技术治疗腰椎管狭窄症的效果显著,可减轻腰腿疼痛,改善腰椎功能,且并发症少,安全可靠,值得临床推广应用。

Objective To study the effect of BEIS technique in the treatment of lumbar spinal stenosis under percutaneous spinal foramina.Methods Using retrospective analysis,64 patients with lumbar spinal stenosis admitted to Taizhou People's Hospital from January 2019 to January 2020 were selected as the research subjects.They were divided into the control group(n=32)and the study group(n=32)according to different treatment methods.The control group was treated with transforaminal lumbar interbody fusion,and the study group was treated with BEIS(Broad Easy Immediate Surgery)technology for percutaneous foraminal removal of nucleus pulposus with radiofrequency ablation;the two groups were compared with surgical indicators(Intraoperative blood loss,operation time,postoperative time in bed,hospital stay),lumbar and leg pain scores after surgery,lumbar spine dysfunction score,and complication rate.Results The intraoperative blood loss,operation time postoperative bed time and hospitalization time of the study group were(61.67±5.63)mL,(59.91±9.73)min,(2.31±1.58)d,(3.94±1.36)d,respectively,which were significantly lower than those of the control group[(326.82±17.46)mL,(118.34±20.16)min,(6.14±1.65)d,(8.41±3.32)d],the differences were significant(P<0.05).The postoperative lumbar and leg pain score,lumbar spine dysfunction score and complication rate of the observation group were(1.52±0.59)points,(7.48±2.21)points,and 3.13%,respectively,which were significantly lower than those of the control group[(3.16±0.78)points,(18.54±7.17)points,21.87%],the differences were statistically significant(P<0.05).Conclusion The application of BEIS technique in the treatment of lumbar spinal stenosis under percutaneous spinal foramina has a significant effect,which can reduce the pain in the back and legs,improve the function of the lumbar spine,and have fewer complications,is safe and reliable.It is worthy of clinical application.
