The aim of this study was to evaluate the clinical usefulness of CO2 laser dissection in patients who had undergone lumbar discal cyst removal.
Clinical and radiological data were reviewed for 14 patients who underwent single lumbar level CO2 laser dissection followed by lumbar discal cyst removal between 2003 and 2008. They were followed up with plain radiographs, and their mean follow-up period was 20.1 months.
Patients' mean hospital stay after operation was 3.5 days. Pain scores on a visual analog scale (VAS) for back and leg pain improved from a preoperative mean of 4.3 and 8.1 to postoperative 1.9 and 1.8, respectively (P<0.001). Clinical outcomes based on the Oswestry disability index (ODI) improved from a preoperative mean of 46.47% to 14.81% postoperatively (P<0.001).
Our results demonstrate that the CO2 laser could be a useful surgical tool for the surgical excision of lumbar discal cysts.
本研究的目的是评估二氧化碳激光解剖在接受腰椎间盘囊肿切除术患者中的临床实用性。
回顾性分析2003年至2008年间14例行单节段腰椎二氧化碳激光解剖并随后进行腰椎间盘囊肿切除术患者的临床和放射学资料。采用X线平片对其进行随访，平均随访时间为20.1个月。
患者术后平均住院时间为3.5天。视觉模拟评分法（VAS）评估的背部和腿部疼痛评分分别从术前的平均4.3和8.1改善至术后的1.9和1.8（P<0.001）。基于奥斯威斯利功能障碍指数（ODI）的临床结果从术前的平均46.47%改善至术后的14.81%（P<0.001）。
我们的结果表明，二氧化碳激光可能是用于手术切除腰椎间盘囊肿的一种有用的手术工具。
